To give you the big picture, there is also a short overview of SAP’s history. When we wrote the first edition of this book in 2015/2016, we had really only wanted to write an article about SAP projects—but then we simply had too much fun writing to stop there. Too many aspects that are essential for the success of a large SAP project had to remain unmentioned in an article. That is why we went ahead and wrote an entire book about it. Technological Change Since then the world has changed enormously. Technological progress in the last decade has led to drastic upheavals: companies are increasing their productivity through more and more automation, which means that the need for human labour is dwindling. Cloud providers such as Facebook, Uber, Workday, Airbnb and many others have created platforms that are fundamentally changing the way we live, work, travel and communicate with others. AI (artificial intelligence) applications have become a natural part of our everyday life (do you still “google” or do you ask Siri or Alexa?). Billions of people carry small computers (smartphones) with them, each of which has more computing power than the supercomputers used to send the first humans to the moon in 1969—and they can even be used to make phone calls. These rapid developments raise many social questions, but this book is mainly about how you as a project manager can contribute to your company’s success in this global competition of the best ideas, the best services, the best products and the most capable providers through modern and efficient IT. Historically, a company’s IT was often seen as a cost factor, but it can now become and important “enabler”, allowing companies to offer new services, business areas and customers. v How Can Your Company Compete in a Global, Digital World? The world has become a different place, but the companies using SAP software and SAP itself have also changed massively, so that a fundamentally revised edition of our book seemed to be called for. Many companies have been using SAP software successfully for years and are now facing a new challenge, the switch from the classic SAP Business Suite to SAP S/4HANA—the new SAP flagship and core product. The question arises whether it is better to wait or tackle this task now? Besides the core SAP products, SAP’s cloud offerings must also be evaluated: starting with the SAP HANA Enterprise Cloud on to the integration platform SAP Cloud Platform as well as SAP Cloud for Customer and SAP Analytics Cloud. Technologies such as machine learning, speech recognition, robotic process auto- mation, blockchain , etc. promise completely new possibilities to stand out from the competition and win new customers and business areas. Today, no company can afford to ignore these developments without jeopardising its own competitiveness and thus its own future. SAP has many interesting products on offer, but it is safe to assume that you will only reap the greatest benefit if you use them together with SAP S/4HANA. SAP’s Biggest Bet and Business Transformation SAP S/4HANA is not only the latest ERP Business Suite from SAP, but the new core of SAP’s strategy, SAP’s biggest and most important bet on the company’s future. Although SAP strives to make the migration to SAP S/4HANA as easy as possible, a closer look reveals: introducing SAP S/4HANA needs to be accompanied—if it is to pay off—by a fundamental corporate transformation. • ERP in the Cloud SAP has been the market leader for years for business-critical systems and data in on-premise ERP systems. Customers should now feel encouraged to migrate business-critical data and processes to the cloud (provided by SAP). SAP S/ 4HANA Cloud, Essential Edition or Extended Edition is SAP’s offering for these companies. Behind this is a new ERP philosophy: a standardised ERP system as the heart of the company, surrounded by additional, specialised SAP cloud solutions and supplemented by customer-specific extensions in PaaS or on-premise SAP applications. • O-Data and X-Data SAP S/4HANA makes it possible to combine operational data (O-Data) with experience data (X-Data), i.e. classic company reports with real-time evaluations of customer preferences and customer satisfaction. This enables companies to react very quickly and flexibly to changing customer requirements. • Artificial Intelligence, Robotic Process Automation, Machine Learning vi Preface SAP S/4HANA opens up the possibility for companies to make future topics such as artificial intelligence (AI), robotic process automation (RPA), machine learning (ML), etc. a reality as part of the Fourth Industrial Revolution and to benefit from them. These massive changes that many companies are facing in the coming years have the potential to become as painful, revolutionary,time-consuming and costly as the first company-wide introduction of SAP ERP software was many years ago—or not, if approached correctly: carefully weighing up opportunities and risks and avoiding common project management errors. In this book, we want to show you how to do this. And what about SAP? SAP has evolved from a somewhat conservative but solid “German” provider of integrated enterprise resource planning software in the 1990s and early 2000s to a global software manufacturer, cloud provider and service provider. Today, Germany remains an important but by no means the most important sales market for SAP products and solutions. SAP has changed at such a pace that some customers are rubbing their eyes and fear they are losing touch. In 2015, when the first version of this book was published, SAP had approximately 66,000 employees—today, five years later, due to organic growth and numerous acquisitions and takeovers, this number has risen to more than 100,000. SAP: From SAP R/3 to Full-Service Cloud Provider in 30 Years In the 1990s, the product range consisted mainly of the core product SAP R/3 and was initially expanded in the early 2000s with logical developments for customer management (SAP Customer Relationship Management, SAP CRM), reporting (SAP Business Warehouse, SAP BW, formerly SAP BI—SAP Business Intelli- gence), supplier management (SAP Supplier Relationship Management, SAP SRM), supply chain management (SAP Supply Chain Management, SAP SCM), etc. In 2008, a reorientation towards cloud software and service offerings began, resulting in an enormous broadening of the product portfolio (see also Fig. 1). The next step was to move away from being a pure software manufacturer to becoming a provider of cloud solutions and IT services for infrastructure and software management. Licence sales are still important, but with almost 70% of sales, SAP today earns its money primarily from “recurring revenues”, i.e. long-term customer contracts with regularly recurring payments, as is customary with cloud offerings, for example. What is certain is that SAP as a company has undergone major changes and has also realigned its focus. This is also reflected, for example, in the company motto, which in 2013 was still “The Best-Run Businesses Run SAP” and in 2016 was changed to “The Cloud Company powered by SAP HANA”. Meanwhile, (since 2019)—admittedly a little less catchy—it is: “The Experience Company powered by the Intelligent Enterprise”. Keywords of technological development are taken up here and point the way into the future of the company. Preface vii A look at the sales figures (Annual Report 2019) also shows the changes that SAP has undergone in recent years: cloud revenues are growing by almost 40% compared to the previous year and reach approximately €7 billion, while revenues from classic software licences are at approximately €4.5 billion in the same period, which is a slight decline. Conclusion: Over the last decade, SAP changed dramatically. You could also say that SAP has reinvented itself as a company and offers its customers the opportunity to keep up with these changes and benefit from them.

Fortunately, this book project was not quite as complex as a large SAP project. Nevertheless, we too worked as an international team at different locations: with three Germans, one Austrian and one American. Yes, we also had to give room to the different cultural attitudes and overcome the linguistic challenges that result from a mixture of German, English, Austrian and Swabian dialects. But we strictly followed the experience-based advice, recommendations and also warnings that you will find in this book. And behold, we completed the project on time, without exceeding the budget, without a case of burnout and hopefully with lasting success! At this point we would also like to mention that we had a lot of fun writing and thank the many people who supported us in many different ways. We would also like to thank Springer, our editor Ms Bethke and the various project managers and project members who gave us interviews to tell us about their experiences in a wide variety of SAP projects. We would also like to thank the colleagues with whom we have worked on many projects over the years. And last but not least, we would like to thank our families, friends and also you. Without the former, we would not have had the time and leisure for such a project, and without “you” we would have no reason to write the book. ix About This Book Before we dive headlong into the world of SAP projects, we would like to answer the following questions: Who is this book written for? What is special about it? Which chapters are there, and what is the best way to read the book? What Is the Definition of an SAP Project? We write a lot about SAP projects in this book—about what makes SAP projects so special and what makes them different from “normal” IT projects. The “Typical” SAP Project Does Not Exist But what do we mean when we talk about an SAP project? After all, there is no such thing as a typical SAP project; instead, you will find SAP projects in all colours and shapes. Are you planning to introduce SAP software for the first time? Are you flirting with SAP S/4HANA or one (or more) SAP cloud offerings? Or are you already a long-standing SAP customer, planning improvements and optimisations of your existing SAP landscape? Do you still run your SAP ERP software on-premise and plan to use cloud services, or have you already arrived in the cloud and even gained experience with hybrid system landscapes? Or are commercial aspects your motivation? SAP is intensively promoting the switch from classic licence agreements with associated support contracts to sub- scription agreements. Instead of a one-off licence fee, you pay a (usually) monthly “software rent” (in a kind of subscription). This is a very interesting offer, as it allows customers to convert capital expenditure (CapEx for short) into operating expenditures (OpEx), which often results in significant cost savings. However, this is only possible in conjunction with an SAP HANA enterprise cloud contract, i.e. your SAP landscapes are operated for you by SAP in its own data centres or at one of the three major hyper scalers (Google Cloud Services, Amazon Web Services and Microsoft Azure). Depending on your answer, you will be faced with many different questions. A key criterion for the preparation and implementation, but also for the probability of xi success of your SAP project, is the size of the transformation. The risk increases exponentially with the transformation size. A great many medium-sized and even more multinational companies took the first major hurdle back in the 1990s or 2000s and mapped a large part of their business processes in SAP software. SAP ERP is widely used in German-speaking countries as well as internationally. (SAP is the undisputed world market leader for business software with a market share of more than 22%.) Companies using SAP ERP are now facing new challenges: On the one hand, the complexity of the SAP product range has increased considerably, not least due to the acquisition of Business Objects,Sybase, SuccessFactors, Ariba and Fieldglass (to name but a few). On the other hand, SAP’s move away from database agnosticism by focusing on SAP HANA and the integration of more and more cloud technologies poses new challenges for IT departments. In this book, we do not go into detail about the special features of individual SAP products or components. Nor are the differences between the individual SAP releases relevant to what we want to describe here. However, the complexity of SAP ERP solutions has increased 50-fold in the last 29 years (since the release of SAP R/3). And we ‘will mention complexity even more frequently on the following pages. Complex Transformations All projects in our combined more than 100-year career, in which we have accompanied or managed SAP projects, have in common that they are complex transformations. But then what is the lowest common denominator in an SAP project, as we understand it? In most SAP projects, the core element is the SAP Business Suite powered by SAP HANA and the Intelligent Suite SAP S/4HANA. Frequently, other on-premise or cloud solutions play a role. The following applies to all these projects: • They are in fact very complex. • SAP S/4HANA is the functional linchpin, but often other SAP applications are also involved. • They have points of contact with non-SAP applications and often non-SAP integration platforms. • They very often consist of distributed or hybrid system landscapes. • The changes these transformations bring about, affect large parts of the company. In this book, we assume that you will also carry out an SAP project that has these characteristics. We will not, or only very rarely, discuss release-specific features in the project. This means that you can use this book within the framework of current and future SAP projects and regardless of whether your project is a “greenfield” project that produces the first SAP application in your company or whether you are carrying out an upgrade or optimisation project. xii About This Book Who Is This Book’s Target Audience? We are delighted that you have chosen this book, because we have written it just for you. By “you” we mean people who, for a variety of reasons and in a wide range of roles, want to (or perhaps “have to”) deal with the implementation of SAP projects. No matter what your motivation is for your interest in the successful implementation of SAP projects, we are sure that you will find something in this book that will help you to accompany and complete your current or even future SAP project with more success and less stress. Core Target Groups This book is primarily aimed at project and sub-project managers in companies that are facing an SAP project (or are already involved in one), SAP consultants, project staff and managers and decision-makers. You can use this book in many ways: for new project members, it is a guide describing the individual project phases and activities. You will learn what to expect in the individual project phases and gain valuable insights into the everyday life of a project manager. You will learn how to offer support and contribute ideas beyond your role in the project, thus proving yourself a particularly valuable team member. For prospective or new project managers, this book is a manual with important tips on pitfalls and critical success factors. Project management is to a large extent a “craft”, i.e. there are good practices that can significantly increase the probability of project success. You will get to know courses of action that start where the usual project management training courses end. We will take you “into the trenches”, where project management practice is often more than just a little different from theory. As a project manager, you can thus rely on proven experience from your first assignment in your new role and systematically steer your project towards success. For experienced project managers, this book is a reference book, and for strategic decision-makers and other stakeholders who want to contribute to the success of a project by making better decisions, this book is a guide. You can read the whole book or consult it on specific issues. How Is This Book Structured? In this book, you will find nine additional chapters, the contents and objectives of which we would like to summarise briefly below: The (Not So) Subtle Difference Chapter 2, “What Makes an SAP Project So Different?”, highlights the special features of SAP S/4HANA projects. It shows what distinguishes an SAP S/4HANA About This Book xiii project from classic IT projects and what the objectives of an SAP S/4HANA project are. From the Ideal Project. . . .. Chapter 3, “The SAP S/4HANA Project: How It Should Be”, describes the conditions that must be met for SAP S/4HANA projects to be successful. To this end, the “Activate method”—the implementation method developed and recommended by SAP—is briefly introduced and a description is given of why its use makes sense. Using the individual phases and tools of this method, we present our ideal project to you. We introduce the individual phases, Discover, Prepare, Explore, Realise, Deploy and Run. In this chapter, everything runs like clockwork—without financing gaps, disputes with the specialist departments about resources and other problems. . . . ..to Project Reality Chapter 4, “The SAP S/4HANA Project: How It Is’s really like”, presents the main pitfalls in SAP S/4HANA projects. Here, too, we follow the SAP Activate Roadmap and show which failures and setbacks are typical for the individual project phases— from planning to go live and support. Soft Skills as a Success Factor In Chap. 5, “The Underestimated Success Factor: People”, everything revolves around the most important resource in the project. We show which qualities and knowledge project managers and project teams need to have in order to work successfully. You will learn what difficulties can arise here and how you can recognise early on, for example, signs of excessive demands on your project team. In interviews with project members, we have evaluated which support the participants would like to receive and which success factors were particularly valuable in their projects. Project Planning, Control and Quality Assurance Chapter 6, “Project Planning, Control and Quality Assurance”, deals with the activities in the project that require a particularly well-structured approach, project discipline and realism. In this chapter, we show you what you should pay particular attention to without taking you too much into the theoretical world of methods, because it is ultimately the success in practice that counts. xiv About This Book From Theory to Practice in the Project Chapter 7, “Examples from Real-Life SAP S/4HANA Projects”, describes the implementation of an SAP S/4HANA project using various sample companies. You will gain valuable insights into how the implementation was successful in practice and what difficulties and challenges were involved. Last but not least, we have compiled some “lessons learned” from our projects with worldwide rollout, which can serve as a basis for future projects. Outside Assistance Chapter 8, “Consultants: Boon or Bane? Benefit or Burden?”, is dedicated to the external supporters of our SAP-S/4HANA project. Here you can find out which roles you may want to assign to external consultants and where they might not be your best choice. You will also find tips on how to find the right partners and what to look out for when filling positions. In addition, there are some reflections on offshore or nearshore teams. The Toolbox for Your SAP S/4HANA Project Chapter 9, “Project Support Tools”, describes some important tools for supporting SAP S/4HANA projects. We do not primarily focus on the completeness or topical- ity of the tools. Rather, we aim to present the tools that are (or had to be) used most frequently in our projects. 12 Commandments for SAP S/4HANA Projects Chapter 10, “12 Commandments fora Successful SAP Project”, without whose observance any SAP S/4HANA project is inevitably doomed to failure, is made available at the end of the book. In the appendix, you will find a glossary explaining the most important terms we use in this book. The bibliography will give you ideas for further reading. Our Approach Project management books are a dime a dozen, including some on SAP projects. What makes this book special? In this book, we would like to present real projects— more specifically: real SAP S/4HANA projects. In doing so, we name the reasons why SAP projects often fail or cannot be implemented in a planned manner. We discuss the prerequisites that should ideally be fulfilled in order to successfully implement a project—and also show why these prerequisites are usually not met. About This Book xv In this context, we present the most common pitfalls and show how you can still manage to bring an SAP project across the finish line. The “human factor” is particularly important to us. We are convinced that without effective change man- agement no sustainable project success can be achieved. In this context, you will come across a number of topics again and again throughout the book. For example, we highlight the importance of the Project Management Office (PMO) in various sections of this book—from different perspectives. Taken from Project Life To bring our book to life, we will give you numerous fictitious project examples that illustrate the dos and don’ts of project work. This book is not about cramming facts, but rather designed to help you recognise yourself and your project. That way you can elegantly avoid mistakes that others made before. Even if we base our examples on the experiences we have had “in the wild”, similarities with living persons or real companies (where not explicitly stated) are purely coincidental. To make working with this book easier for you, we use information boxes to indicate special notes and tips: • Note:Warns you of common errors or problems that may occur. This symbol also highlights references to e.g. further information on the discussed topic. • Tip: We have marked tips that will make your SAP project easier.

About the Authors xxv Introduction 1 1.1 SAP Solutions: From the Beginning to Today When SAP was founded in 1972 by five former IBM employees, the company started with an idea that would revolutionise the world of ERP (enterprise resource planning) software. Electronic data processing (EDP) was not yet widespread in small- and medium- sized enterprises, not least because of its high cost. Only large companies used mainframes (often from IBM) in certain areas of their business. Although these systems filled entire rooms, their computing power and applications were very limited from today’s point of view. Batch Processing A major problem was the delayed posting of business transactions: databases were usually updated once a day, i.e. business transactions such as goods movements were collected during the day and then posted overnight in batchmode. The next morning, the databases were synchronised with the actual stocks, but during the day, changes were not posted directly but collected until the next nightly batch processing. As the day progressed, therefore, the data stock increasingly deviated from the actual stock. Real-Time Instead of Nightly Batch Processing The revolutionary idea was to make all data changes real time; this means writing to the central database in real time (the “R” in SAP R/3 stands for exactly this). Instead of only finding out the next day whether their bookings had been successfully completed, employees could now always rely on the correctness and topicality of the data. They were also able to reliably answer enquiries, e.g. about the availability of goods. The first SAP products were solutions for accounting (real-time financials, RF) and materials management (real-time materials management, RM), which were introduced to the market in 1973 with the first product SAP R/1.

It contained the most important functions necessary for the control of an internationally operating company: financial accounting, purchasing and merchan- dise management, warehouse management, production planning, quality manage- ment, sales, logistics and human resources. SAP’s response to the emerging client-server-based systems was the even more successful product SAP R/3, which was launched on 6 July 1992 (see Fig. 1.1). Back then, the SAP development team allowed themselves the joke of immortalising the date by making it the default password of the two central admin users SAP* and (in reverse order) DDIC. “R” again stood for real time and “3” for both the third software product and the three levels (three-layer architecture or three-tier architecture): a client-server software architecture consisting of database, application server and frontend (SAP GUI). 1.1.1 One SAP ERP System for All Business Areas SAP ERP is a software that covers all important business areas of a company, from purchasing, production, sales, warehousing, materials management, human resources to finance, which is scalable and stores all data in a central database: this was a very attractive offer for companies that previously only had the choice between very expensive mainframe computers, self-developed individual solutions and many smaller products with limited functionality, e.g. missing or hardly opera- ble interfaces. Mainframe Computer, In-House Development or Standard Software? At that time, mainframes were already mature, high-performance systems that could cover a large part of business transactions. However, they caused high acquisition R/3 Client / Server ABAP Logis�cs SD Sales & Distribu�on MM Materials Management PP Produc�on Planning QM Quality Management PM Planned Maintenance Human Resources HR Human Resources Financials FI Financials CO Controlling TR Treasury Cross-Func�onal PS Project System WF Workflow IS Industry Solu�ons Fig. 1.1 SAP R/3: Overview of the modules 2 1 Introduction and operating costs and required complex adaptations to company-specific requirements. Such an investment was only worthwhile for large companies. Individual solutions have the advantage of being tailored to the respective business requirements but also entail a number of risks: at the beginning of an in-house development, one does not know whether the final product will meet all requirements. Will it be stable, performant and adaptable? What about long-term operation and software maintenance? Can changing legal requirements be implemented cost-effectively? These risks should not be underestimated: an invest- ment in a comprehensive in-house development can influence the economic success of the entire company for better or for worse. Special applications for individual company areas or specific tasks offer the great advantage of often combining the best functionality with the simplest operability (so-called best of breed), a dream for end users but a bit of a nightmare for the IT department, because operating these solutions presents them with major challenges. In addition to the many point-to-point interfaces, which have to be tested again and again with each new program version (and adapted if necessary), topics such as master data management, monitoring and consistent backup/restore are also causing headaches. Such special applications can do their tasks much better than standard software such as that offered by SAP, but the operational deficits and risks speak in favour of using standard software in the long term. 1.1.2 Standard Software as an Alternative to In-House Developments SAP offers an attractive alternative: standard software includes numerous standard processes for all company areas from the outset. Customers receive an adaptable software template for their business processes, which they can adopt with simple settings or adapt, extend and modify as required. SAP customers have always been supplied with the entire sourcecode and a powerful development environment, which allows company-specific process enhancements, additional developments and modifications to be easily implemented. Originally, SAP R/3 was written in ABAP (Advanced Business Application Programming), a programming language developed by SAP itself, a 4GL ( fourth- generation language), which is designed to be able to develop entire applications with as few lines of code as possible. With each system, SAP delivers a powerful development tool that enables development projects to be implemented in a very short time, especially due to the reusability of existing routines and data structures. In addition, SAP offers numerous customising settings that allow the SAP software to be adapted to the specifics of the company without any programming knowledge. Open interface standards enabled communication with external applications, customers and suppliers. 1.1 SAP Solutions: From the Beginning to Today 3 80:20 Rule for Standard Software SAP’s claim was and is to cover approx. 80% of a company’s business processes out of the box—the remaining 20% can be added or adapted by customers through customer-specific developments. By delivering the source code and the corresponding development environment—including an open extension standard by the way—there are virtually no restrictions for customers to adapt the software to their needs. The SAP business processes, which were conceived by SAP and tested thousands of times, promised a solid process model for almost all companies. SAP was also able to score points with continuous improvement and further development as well as future—proofing through long maintenance cycles. Internationally active companies also appreciated the multi-language capability, which allowed them to easily map different character sets (e.g. Latin and Chinese) in one system. Experience shows that it is better to adapt the company to SAP software than to adapt the software to the company, because a standard software that deviates greatly from the standard loses its key advantage and costs a lot of additional money over the years as the deviations must be adapted and tested each time the SAP standard software is updated. But there were (and still are) restrictions: standard software is never so precisely tailored to the company’s requirements that there is no need to make any concessions. Experience has shown that customers who have adapted their organisational structure and business processes to the SAP processes they had in mind have been more successful in the long term than customers who have (drasti- cally) changed the SAP standard software to adapt it to their previous organisational structure and their own processes. SAP R/3 could be changed massively, but in the long run, they paid a high price for it, as any new version had to be extensively analysed, tested and, if necessary, adapted again. And this is the best-case scenario. Some customers found out the hard way that they had modified the standard SAP software so fundamentally that it was no longer possible to implement newer versions. They had the choice of either staying on their release indefinitely (which was really not an option) or re-implementing SAP. The great commercial success of SAP R/3 triggered an initial, very strong growth phase in the 1990s. Between 1991 and 1996 alone, SAP’s turnover increased fivefold. In order to cope with the rush of customers, an extensive partner network was established, which carried out the implementation of SAP R/3 (and later the successor products SAP ERP and SAP Business Suite) for many customers worldwide. Key to SAP’s Success: The Global Partner Network The establishment of an extensive partner network was crucial to the global success of the SAP ERP software, as many more customers could be served than SAP could ever have done with its own employees. It was also a lucrative business for both sides: the partners provided the consulting experts—often with in-depth industry know-how and years of project experience—and earned money on the 4 1 Introduction implementation, which often took many months or even years. They had the opportunity to establish a lasting partnership with end customers. SAP, on the other hand, earned from the licences and the subsequent support business. An attractive software product and a successful partner model were the key to SAP’s success. At the beginning of the 2000s, SAP thus rose to become the world market leader for ERP software, growing at breath-taking speed in Germany as well as worldwide and continuously expanding its software range. Industry solutions were developed, of which there are now more than 30, covering the needs of, for example, the manufacturing industry, the service sector, consumer goods manufacturers, energy companies and the public sector. The next step was to extend the monolithic SAP R/3 system by developing the SAP Business Suite. 1.1.3 Overcoming the Monolithic SAP ERP Architecture SAP Business Suite In the first decade of the new millennium, SAP R/3 was a mature product, but as a “one-size-fits-all solution”, it could no longer meet all customer requirements. In order not to increase the complexity of the core product any further, specific solutions were created with the SAP Business Suite for business subareas: • Customer management (SAP CRM) • Reporting (SAP BW, formerly SAP Business Intelligence, SAP BI) • Warehousing (SAP Extended Warehouse Management, SAP EWM) • Procurement management (SAP SRM) • Supply chain and supplier management (SAP SCM) The basis for these new products was the common application platform SAP NetWeaver. This common application environment ensured smooth operation and close integration of the systems. SAP NetWeaver was (and still is) the common foundation for the SAP Business Suite applications and provides numerous common functions. These include user management, development environment, database management, web server, etc. The expansion of the product range was accompanied by the introduction of a further programming language: in addition to ABAP, applications were now also developed in Java. In 2004, SAP R/3 was converted to SAP ECC (SAP Enterprise Core Component) and together with SAP CRM, SAP BW, SAP SCM, etc. marketed as SAP Business Suite. Other products were added to round off the offering: 1.1 SAP Solutions: From the Beginning to Today 5 • SAP Portal provided a configurable entry interface and landing page for customers. • SAP NetWeaver Exchange Infrastructure, SAP Process Integration, SAP Process Orchestration SAP NetWeaver Exchange Infrastructure, later renamed SAP PI (SAP Process Integration) and finally SAP PO (SAP Process Orchestration), is a central inter- face hub for internal and external data exchange. The aim of SAP PO is to replace point-to-point connections between IT systems (not only SAP) with an interface hub, which facilitates monitoring, maintenance and troubleshooting: nearly all adjustments can be made at one central point in the PO system. Two topics were the focus of the development of these new products. Special processes, for example, reporting or supply chain management, were outsourced to dedicated applications. This made it possible to include more customer requirements than would have been possible in SAP R/3—and the common SAP NetWeaver platform ensured the close integration and easy operability of all components of SAP Business Suite. Customers were able to decide whether the functionality covered by SAP R/3 (or SAP ECC) was sufficient for them or whether the additional process requirements of the specialist departments should be covered by the new SAP special applications without having to make compromises in the area of operability or data integration. Standard Software vs. “Best-of-Breed” SAP had taken up the challenge with the promise that standard software, which covers practically all areas of the company, would be more stable and more cost- effective to operate in the long term, morereliable and more efficient than in-house developments or special solutions for individual company areas. This is known as the standard software vs. best-of-breed approach. “Best-of-breed” Software may offer better features, but in terms of operability, standard software is better, leading to the quip: Standard (software) is better than “Better Than Standard”. Although SAP’s standard software products were in some cases not always the best on the market in terms of functionality and user-friendliness, a decisive advan- tage of these solutions from the customer’s point of view was their close integration into the overall solution portfolio: they were based on the SAP NetWeaver Applica- tion Server (SAP NetWeaver AS) and were therefore easier for customers to operate than special solutions from different suppliers, some of which are difficult to integrate. Many companies also appreciated the fact that they only had to deal with one supplier when software problems arose—not several, whose default answer was that their software was of course error-free and that the error was surely to be found with the other supplier. In a worst-case scenario, the company’s core IT systems are down and the software providers are passing the buck to each other. 6 1 Introduction 1.1.4 Acquisitions, Cloud Company, SAP HANA The acquisition of “Business Objects” marked a turning point in SAP’s strategy. Until then, SAP had focused on organic growth, an integrated software portfolio and its own innovative strength. However, the limits of its own growth seemed to be approaching. Now the company began to buy up innovations from the market: the takeover of the French business intelligence specialist Business Objects in the same year was the first major acquisition that required the integration of a completely foreign software stack into the solution portfolio. Organic Growth Is Not Enough: SAP Goes on a Shopping Spree After SAP was accused of underestimating the importance of the Internet for too long in the early 2000s, SAP reacted quickly: as early as 2014, SAP described itself as “The Cloud Company powered by SAP HANA”, and the Walldorf-based com- pany implemented this goal with great determination in the following years. From 2008 on, SAP went on a shopping spree and in 11 years took over more than 20 software manufacturers, most of which offered cloud-based solutions: Sybase in 2010, SuccessFactors 2011, Ariba 2012, Concur in 2014 and Callidus in 2018. In the same year, SAP bought Qualtrics, the most expensive acquisition in the company’s history, at a price of around €6.4 billion. In this way, SAP acquired numerous innovative software solutions but paid a high price (some believe it was too high), not only financially: the much-vaunted, exemplary integration of SAP software on a common application server was history. On the one hand, there was the well-integrated SAP Business Suite and, on the other hand, third-party products that needed to be integrated into the portfolio in the following years. The initial “integration” of Ariba via CSV file interface is indicative of the challenges SAP faced and what the customers had to put up with. On the one hand, the business departments on the customer side cheered in view of the new functionalities and offers. IT departments, on the other hand, were less enthusiastic as operations became considerably more complicated, costly and less reliable. Nevertheless, the core product and the cash cow was and remained SAP Business Suite, a mature, solid product but one that was becoming technologically outdated, having its roots in the 1990s. Through continuous development, it had evolved into a complex, scalable yet easy to operate software. Customers appreciated its stability and extensive functions, but the user-friendliness and user guidance in the proprie- tary SAP GUI (SAP Graphical User Interface) were perceived by many customers as no longer up to date. SAP responded first by introducing the new Business Client user interface and later with SAP Fiori. However, it has not yet managed to completely replace the old SAP GUI. The ever-increasing data volumes also caused problems for some customers, and cloud computing was out of the question with this software. SAP Business Suite was a well-designed, consistent on-premise software—at a time when the market for cloud software was quickly becoming the market of the future par excellence. What could SAP do now to keep up with this market trend? 1.1 SAP Solutions: From the Beginning to Today 7 1.1.5 Cloud and SAP HANA At this point, two parallel, actually independent developments intersect, which ultimately come together: the trend towards “cloud” and the development of the SAP HANA in-memory database. Led by company founder Hasso Plattner, a revolutionary new database technol- ogy was developed from 2008 onwards: SAP HANA (High-Performance Analytics Appliance). In contrast to relational databases (mostly those of the American com- petitor Oracle), which used to store customers’ business data on storage mediums, SAP HANA is an in-memory database that can offer massive performance improvements—and ultimately completely new possibilities for real-time data processing and analysis. SAP HANA Versus Relational Database Systems Relational database systems, which had previously been the basis for SAP business applications, reached their limits in the face of ever-faster data growth. The need for ever-more powerful servers and performance problems with large amounts of data were the result. While relational databases had to repeatedly read and save data from hard disks or other (relatively slow) storage media, SAP HANA took a different approach. The entire database was stored in the fast, random access memory (RAM) of the server. The company switched from line-oriented data management to column orientation and thus achieved a considerably reduced data volume and an enormously increased performance, especially for read reporting tasks. Supported by the falling price of memory modules and increasingly powerful servers, completely new application possibilities arose for processing real-time data and data streams and for analysing large amounts of data. This is begging the question: “And what if the power fails?” For performance reasons, only data changes are backed up in slim log files on permanent data storage devices. This means there is no risk of data loss even in the event of a sudden power failure. The SAP HANA log files protect reliably against data loss but also lead to longer startup times, since all data must first be loaded into the server’s working memory when restarting. This can take 30 minutes or more on larger systems. So the fast processing speed has its price in daily operations. Ending Support for Numerous OS and DBMS The next major event was the release of SAP Business Suite on the new in-memory database SAP HANA in 2013. SAP software was previously largely “agnostic” when it came to OS (operating system) and DB (database), i.e. it could be operated as desired on a number of common operating systems and databases from various suppliers. Customers appreciated this flexibility. Most of SAP’s customers used the Oracle database, which led to the astonishing situation that for many years, SAP was the largest licence vendor for its closest competitor. 8 1 Introduction On the other hand, this led to high costs for SAP. Each new software version had to be extensively tested on several operating systems and database systems before delivery. It is an open secret that not all OS-DB combinations could be thoroughly tested. Especially with more “exotic” combinations, it was the customers who found some bugs. In addition, error notes had to be created and maintained, sometimes specifically for individual databases and operating systems. Furthermore, SAP was forced to maintain installation guides and other documentation for numerous OS-DB combinations. The openness for different operating systems and database systemsreduced the training expenses for the customers, as they could switch to products for which the company already had know-how—but it cost SAP dearly. SAP HANA and Linux Are the Future Through the introduction of SAP HANA, this situation was brought to an end: now, the in-memory database SAP HANA and the Linux operating system are exclusively part of the SAP software stack. This is an about-turn, as other operating systems and databases have since then played practically no role in SAP’s product strategy. Only the ASE and IQ databases acquired as part of the acquisition of Sybase are used in certain cases and some special products. The switch to SAP HANA as the one and only database for SAP software was a hurdle for SAP customers that should not be underestimated. • SAP HANA requires specially certified hardware, which is expensive to purchase. • The Oracle/DB2/MS-SQL server know-how developed over the years lost its importance; instead, SAP customers’ IT departments had to build up new SAP HANA know-how to be able to operate the new database. Smaller companies, in particular, which had mostly relied on easy-to-run Windows-based servers, initially struggled with the very different, non-commercial, free operating system Linux. SAP Business Suite: Full Throttle with Handbrake Applied The first step was to adapt the SAP Business Suite so that it could run on the new in-memory database. But SAP Business Suite had been developed for relational databases and could not really exploit the strengths of the SAP HANA database. In a hurry, performance optimisations were made in the SAP Business Suite to demon- strate to customers the superiority of the SAP HANA-based Business Suite (today’s name: SAP Business Suite powered by SAP HANA). Good results were achieved in reading operations, while in writing operations, the success was rather limited. Apart from SAP BW—a system that mainly performs read operations for the display of reports—the move to SAP HANA on the classic SAP Business Suite did not actually bring such great benefits for SAP customers that the high implementa- tion costs for new hardware, training of staff, etc. actually paid off. 1.1 SAP Solutions: From the Beginning to Today 9 The decision was inevitable: SAP’s flagship product, SAP Business Suite, had to be developed in a new version specifically for SAP HANA in order to take full advantage of the new possibilities offered by in-memory technology. 1.1.6 SAP S/4HANA: The Largest Investment in the Company’s History The SAP Business Suite was written over decades by thousands of SAP developers and consists of millions of lines of code—a new development was a unique challenge and is the largest investment in the company’s history. Considerable development resources have been and will be tied up for years to come. SAP S/4HANA: Impressive, but Customers Still Hesitate In 2015, the time had come: SAP S/4HANA, an SAP ERP solution specially developed for the in-memory database SAP HANA, was presented. It was impossi- ble to implement the functionality of the classic SAP Business Suite in SAP S/4HANA within 2 years; therefore, the first step was to focus on FI/CO (Finan- cials/Controlling) and offer this “slimmed down SAP ERP”. In the following years, the functionalities were successively extended. The goal was never to create merely an in-memory version of SAP ERP. Instead, the focus was on simplification and optimisation of business processes. In the meantime (as of spring 2021), the SAP S/4HANA on-premise solution with 35 supported languages, 61 country versions and 23 industry solutions has caught up considerably with the SAP Business Suite. For SAP, this has been an enormous effort, which goes to show what this company is capable of. The result is impressive, but it has not yet led to a mass migration of SAP customers to the new core product. SAP software forms the IT backbone of many companies and is used in the most critical business areas. If it fails, large parts of the company are no longer able to work. Operations come to a standstill. Every major outage costs a lot of money and, in the worst case—assuming the outage lasts for days and weeks—can threaten the company’s existence. SAP Customers: Never Touch a Running (SAP) System SAP customers are therefore very conservative and risk-averse: reliability, stability and operability are decisive factors for business-critical IT systems. The vast major- ity of SAP customers run the core of their applications in their own data centres. Many, particularly smaller companies, have transferred operation to experienced hosting providers specialising in SAP. Innovations are carefully evaluated, tested and introduced step by step to minimise business risk. The growing importance of cloud-based solutions was already foreseeable in 2013; therefore, SAP S/4HANA was developed from the beginning as an on-premise solution and in two further variants as a cloud solution. SAP is 10 1 Introduction performing a balancing act here and, on the one hand, responds to the demands of major customers who want to operate their core applications in their own data centres with the SAP S/4HANA on-premise solution. On the other hand, the SAP S/4HANA Cloud solution is designed to open up new business areas and customer markets. Although cloud solutions offer far fewer possibilities to adapt them to specific customer requirements, their monthly sub- scription rates mean that they represent a lower investment, can be consumed more quickly and reduce the need for in-house IT specialists. Cloud solutions also offer a host of other important advantages: • Scalability Cloud solutions can be easily adapted to the company’s requirements—more computing capacity or less: just as the business requires! • Connectivity. Cloud allows mobile data access worldwide and around the clock via PCs, laptops or mobile devices. • Flexible workstations Since all data is stored in the cloud, the location of the workstation is no longer important. Whether in the office, at home or abroad—as long as the data connec- tion is stable and fast enough—it doesn’t matter anymore. Employees have the privilege to be able to work from anywhere. • Data security Cloud solution providers offer security systems for customer data that are far more professional than what small companies can do on their own. For customers who cannot or do not want to do without the advantages of the cloud and the configurability of on-premise solutions, there is the possibility to combine the best of both worlds: hybrid system landscapes (i.e. partly on-premise, partly in the cloud) allow business-critical applications to continue to operate as on-premise applications; new areas of application can be introduced and used quickly and cost-effectively using cloud software. The requirement for SAP S/4HANA was therefore not only to become the new and improved SAP Business Suite, but the stated goal was to integrate with SAP cloud offerings—and these are now quite a few, thanks to acquisitions and solutions developed by SAP itself: • SAP SuccessFactors: cloud-based HCM solution (acquisition) • SAP Ariba: cloud-based trading networks (acquisition) • SAP Customer Experience: E-commerce (acquisition) • SAP Fieldglass: cloud-based temporary employment management (acquisition) • SAP Concur: travel and expense management (acquisition) • CallidusCloud: cloud-based distribution software (acquisition) • Qualtrics: cloud-based enterprise feedback management (EFM) (acquisition) • SAP Analytics Cloud: SaaS cloud (software as a service), especially for reporting (proprietary development, based on SAP Business Objects) 1.1 SAP Solutions: From the Beginning to Today 11 • SAP Sales Cloud: SaaS cloud for CRM (in-house development) • SAP Marketing Cloud: SaaS cloud for marketing (in-house development) • SAP Service Cloud: SaaS cloud for customer service and after sales support (in-house development) • SAP Cloud Platform: PaaS cloud (platform as a service) for the integrationof cloud and on-premise landscapes (proprietary development) • SAP HANA Enterprise Cloud: PaaS cloud for operating customer landscapes in SAP-owned or hyperscaler data centres (infrastructure service) 1.2 Current SAP Software Solutions and Outlook Over the last decade, SAP has massively expanded its range of software solutions and especially its cloud offerings. At the same time, there has been a huge invest- ment in new technologies. From 2012, former SAP CEO Dr. Henning Kagermann became a leading representative of the future project Industrie 4.0 in Germany, a vision of intelligent, digitally networked systems, on the basis of which self- organised production should become extremely advanced. The focus was (and still is) the automation of production and IoT scenarios (IoT, Internet of Things) through which physical and virtual objects are connected and cooperate via information and communication technologies. Evaluations of the enormous amounts of data generated in this process are made possible by big data applications, which in turn are based on the very fast SAP HANA database. Industrie 4.0: Machine Learning, AI, IoT In parallel, SAP developed fascinating new functions initially called SAP Leonardo, e.g. block chain, machine learning and big data. RPA (robotic process automation) as part of machine learning, artificial intelligence (AI) and IoT was successively integrated into SAP products: RPA can use chatbots to speed up administrative tasks and improve customer experiences. IoT creates new possibilities in the digitalisation of the logistics chain, not to mention big data applications—the list goes on and on! Numerous acquisitions, especially from cloud software providers, have opened up new customer and business areas. Cloud and subscription models offer customers commercially very attractive new possibilities (and, unlike one-time license fees, provide SAP with stable, recurring revenues). SAP is evolving from what has some- times been disrespectfully referred to as a “software shop” into a full-service provider that combines the development and operation of software solutions in one hand. In 2019, a strategic partnership was agreed with Microsoft. The so-called Embrace programme is designed to encourage customers to use SAP software on the Microsoft Azure Hyperscale infrastructure. However, this is not an exclusive partnership—Amazon (Amazon Web Services) and Google (Google Cloud Plat- form) are also supported. Although SAP operates more than a dozen data centres with thousands of customer landscapes worldwide, the company is obviously relying on the economies of scale in the infrastructure area for future growth that only 12 1 Introduction hyperscalers can offer. In the future, SAP will focus on the upper parts of the software stack and intends to operate as a full-service provider in this area. 1.2.1 The Experience Company Powered by the Intelligent Enterprise X- and O-Data for the Intelligent Company Since the acquisition of Qualtrics, SAP’s new corporate motto has been “The Experience Company powered by the Intelligent Enterprise”. This means that the combination of operational business data (O-data) with customer satisfaction data (customer experience data, X-data) allows companies to deliver a specifically tai- lored shopping experience to their customers and thereby meet customer expectations. The result is the Intelligent Enterprise (Fig. 1.2). The heart of the system remains the SAP S/4HANA system, now called the intelli- gent ERP suite. It consists of the ERP system, digital logistics, customer experience and Intelligent Spend and Human Experience Management (HXM) solutions. Mod- ern technologies, such as machine learning, AI, blockchain, Internet of Things and analysis functions, are used as integral components of SAP software products and allow O-data to be combined with X-data. The concept consists of the following components: 1. Intelligent Suite • The Intelligent Suite includes enterprise resource planning (ERP), digital supply chain management, customer experience, Intelligent Spend Manage- ment and Human Experience Management. It is modular, yet the individual Network & Spend Mgmt People Engagement Digital Core Manufacturing + Supply Chain Customer Experience Intelligent Technologies AI Machine Learning Analytics IoT Intelligent Suite Digital Platform Cloud Platform Data Management Fig. 1.2 SAP Vision: Intelligent Enterprise 1.2 Current SAP Software Solutions and Outlook 13 applications are fully integrated. Industry solutions also offer industry-specific processes and end-to-end scenarios. 2. Business Technology Platform • The Business Technology Platform is the control centre and the technical foundation for the Intelligent Suite and supports the conversion of company data into business values. It comprises database and data management functions, application development, integration, analytics and intelligent technologies on-premise and in the cloud. In future, all SAP solutions will be based on the Business Technology Platform, which means a fundamental shift away from the attempt to integrate basically independent, vertical soft- ware stacks towards a common, integrated software stack. 3. Experience Management (XM) Experience Management enables organisations to focus on four areas: customers, employees, product and brand. The API integration between XM and the Intelli- gent Suite provides the link between X-data and O-data. A shift in emphasis from earlier times is evident. It is no longer just about productivity gains through standard software but about technologies to help companies bring innovations faster to market while putting the customer experience and customer feedback at the heart of business decisions. In doing so, they must not lose sight of the well-being of their employees and the perception of their own products and brand. On the contrary, fast reaction to changing customer preferences and continuous feedback on the customer experience are factors that are becoming increasingly important and can decide on business success. 1.2.2 SAP S/4HANA: A Slow Seller? The SAP flagship SAP S/4HANA has not yet been able to achieve its sales targets. Although SAP now has more than 440,000 customers and 12 million users, SAP S/4HANA is only used by about 14,000 customers (as of spring 2020). The largest investment in the company’s history has therefore not yet paid off. The development of SAP S/4HANA was certainly the right decision: sales are picking up and SAP is in it for the long haul anyway. Many existing SAP customers often stick with older SAP software versions for business-critical applications and are hesitant to use newer products in their central business processes. In response to pressure from SAP user groups and major customers, SAP has extended its maintenance commitment for SAP Business Suite 7 until the end of 2027 (extendable to 2030). SAP S/4HANA will remain in maintenance until at least 2040. That is an unusually long commitment in the fast- changing software industry. SAP S/4HANA: Key to Success After the major shopping spree of the last decade, SAP has realised what customers are missing and what may be holding them back from switching to SAP S/4HANA or the Intelligent Suite: 14 1 Introduction • Even if things are progressing steadily and the gap is closing, SAP S/4HANA still does not have the complete functional scope of the SAP Business Suite. • The SAP S/4HANA data model has been simplified compared to the SAP Business Suite. This means that existing extensions (investments in the SAP Business Suite) cannot always be transferred without problems. Expensive adjustments or new developments may be necessary just to restore the current functionality on SAP S/4HANA. This potentially incurs high costs but brings little added value to the business. That is not an easy sell. • The number of on-premise and cloud products, with partial functional overlaps, confuses customers with regard to future-proofinvestments. • The end-to-end mapping of business processes across the various software offerings has become complex and has so far not always achieved the stability and resilience that customers are used to from the on-premise world. • Business issues, especially in hybrid landscapes, bring new challenges, e.g. in terms of monitoring and consistent backup/restore of business processes across the landscapes, which run partly on-premise and partly in the cloud. • The version management of the various SAP cloud and on-premise products requires careful planning if frequent updates are to be avoided. When SAP’s new CEO, Christian Klein, replaced long-time SAP CEO Bill McDermott in October 2019, a strategic reorientation began, focusing on a stable, easy-to-manage, integrated SAP product portfolio, concentrating on core areas and paying increased attention to cooperation with partners. Bill McDermott led SAP into the cloud era; Christian Klein is now consolidating the product portfolio and structuring it in such a way that it meets customers’ high demands for operability, planning reliability, integration and stability. 1.2.3 On-Premise or in the Cloud? SAP continues to see a large market for on-premise software in industries with high process complexity, such as manufacturing and the automotive industry, where ERP adaptations are required. This is also true for companies in countries with political instability, limited infrastructure or increased data security concerns. The introduc- tion of a public-cloud infrastructure is certainly not possible there in the near future. Cloud, On-Premise Solution or Both? Cloud solutions however, are becoming increasingly important in other areas of the business: human resources, procurement, the front office and customer relationship management (CRM). SAP will offer modular cloud solutions but also ensure a strong integration into the ERP core. Technical integration is one thing—the integration and innovation of business processes end-to-end is the second important aspect that SAP will focus on. 1.2 Current SAP Software Solutions and Outlook 15 The (Maintenance) End Is Near! In view of the foreseeable end of maintenance for the classic SAP Business Suite, more and more customers will have to deal with the topic of introducing SAP S/4HANA in the core areas of their company in the coming years. This often resembles open heart surgery and carries many risks. Good preparation, planning and implementation (usually supported by external consulting experts) are the key success criteria. On the one hand, one should not start too early, because important functionalities might not yet be available or at least not mature enough. On the other hand, one should not start too late, not only because the competition may have a competitive advantage by innovating earlier, but also because more customers (have to) start upgrade projects before the end of maintenance, which is getting closer and closer. This is likely to make it all the more difficult to find well-qualified consulting support on the market. When is the right time to start the switch to SAP S/4HANA? This book will help you answer this question. 16 1 Introduction What Makes an SAP Project So Different? 2 Let us start with a look at the figures: statistically speaking, a considerable number of IT projects are not successful. A number of studies over the last two decades have measured the success or failure of IT projects and came to the conclusion that approx. 40% of the IT projects examined were completed successfully. This means that budgets were met and the expected functions were made available within the planned timeframe. About 40% of the projects were completed with restrictions, and about 20% were cancelled. In other words, less than half of all IT projects are a success—the vast majority fail partially or completely. The reasons for the failure of the projects were the lack of involvement of end users, the lack of clear objectives, insufficient requirements management and lack of management support. Are we dealing with new findings here? The answer is “no”. The study confirms our experience from many projects. Interestingly, although these stumbling blocks are sufficiently well known, the same mistakes are made in projects again and again. When you analyse these studies in more detail, it becomes clear very quickly that many reasons for the (partial) failure of projects lie either in the responsibility or at least within the sphere of influence of the project manager. Of course, the success of a project depends on many factors: a successful project is always the success of a well-functioning team, with sufficient qualification, motivation, time, management support and a clearly defined scope. But you as a project manager have a very special role—you are not the leading actor but the “director”, who makes sure that all “actors” play their parts at the right time. Even if you already have experience managing IT projects, you will face completely new challenges in your SAP project. Because SAP projects are different! But what distinguishes an SAP project from a conventional IT project, such as the replacement of old hardware with new, more powerful servers or the relocation of IT Supplementary Information The online version of this chapter (https://doi.org/10.1007/978-3- 030-86084-4_2) contains supplementary material, which is available to authorized users. # The Author(s), under exclusive license to Springer Nature Switzerland AG 2022 D.

Is it the processes that need to be mapped in an ERP system like S/4HANA? Is it the system architecture, which has become increasingly complex over the past decades? Is it the way in which the data has to be migrated from the old systems? Is it the impact on the overall organisation of a company? Five times “yes” to that. 2.1 What Distinguishes IT Projects from Business Transformation Projects with SAP Companies today are under increasing pressure to change and optimise their busi- ness models and processes in order to be successful in global and regional markets. If they are not already using SAP ERP software, now is a very good time to kick-start this transformation process. If you have already been using SAP—possibly for many years—now is also the right time to take the step into the new S/4HANA world: • S/4HANA, particularly the Intelligent Suite, has reached a good functional level and is offered in a host of different versions for on-premise and cloud. • S/4HANA know-how is now available at many consulting companies in suffi- cient quality and quantities. The demand does not yet exceed the supply of qualified consultants—this will probably change when the end of mainstream maintenance of the classic Business Suite is approaching 2027 or at the latest 2030 for extended support. • An indication that S/4HANA has arrived on the market is shown by surveys of user groups: SAP customers in the German-speaking countries and in North America are planning significantly higher investments for S/4HANA in the next few years. A considerable number intend to tackle the migration in the next 3 years. From IT Project to Business Transformation But let’s take a look at the individual types of IT projects first: Between a pure IT project and a company transformation, e.g. with SAP, there are different levels in terms of complexity, number of project participants and scope of changes: • Pure IT project In a pure IT project, the focus is on activities such as the replacement of hardware or a purely technical upgrade. Theproject is mainly implemented by employees of the IT department. Processes and organisation are not part of the IT project and usually not affected by it. • Standardisation/harmonisation The next stage involves the standardisation of data and transactions. For example, by standardising customer master and product data in the company, improved reports and analyses can be made available to the management for corporate decision-making. Such suggestions for improvement come primarily from the IT departments; the business departments are involved only as needed. A revision of 18 2 What Makes an SAP Project So Different? the business processes, however, does not take place, or only to the extent that is absolutely necessary. • Optimisation/redesign of business process flows With the optimisation and redesign of business processes, it is possible, for example, to handle the entire order process more efficiently. Unnecessary process steps or system breaks can be removed, with positive effects, e.g. on the delivery times of products and thus also on customer satisfaction. Such projects are carried out in close cooperation between IT and business departments. • Company transformation with SAP standard software The next stage is characterised by significant changes in business models, pro- cesses and organisational structures. There is a strong management commitment to these process changes. The business departments are closely involved in the project and assume responsibility. From beginning to end, such a project usually takes years and passes through various phases: first, there is the recognition by the management that there is a need for change. Usually this realisation is accompanied by an idea of which business models are to be implemented with which process flows and organisational adjustments. Then, a step-by-step plan is drawn up, in which order and in which timeframe the changeover to SAP software should take place. One usually starts with less business-critical systems or company areas, and then, after the team has come together and has a wealth of experience from the first go-lives, one ventures on to the more critical IT systems. Affected Business Areas Which areas are affected by such a transformation project, and what measures are necessary? The following should be mentioned in particular: • Optimisation of business processes The optimisation of business processes is supported by the use of ERP standard software. This involves redefining cooperation within the company as well as customer and supplier relationships. The integrated, end-to-end business pro- cesses, based on common master data, offer enormous potential for productivity increases and quality improvements. • Organisational adjustment The introduction of ERP standard software often leads to changed organisational structures that are adapted to the new standardised processes and business models. We strongly recommend that you adopt the preplanned organisational structures from SAP as much as possible. The more you adapt SAP to your company organisation, the more you lose many of the advantages of standard software and pay a high price in the long run. • Organisational change management The change processes in corporate transformations are considerable. In order to strengthen the willingness of stakeholders and employees to change, change management methods are used to support them. Unfortunately, this area is often neglected with oftentimes adverse effects on project success. Remember concerns, fears and resistance within the company that are not taken seriously 2.1 What Distinguishes IT Projects from Business Transformation Projects with SAP 19 can endanger the acceptance of the new software—and thus the success of your project (more about this in Chap. 5, “The Underestimated Success Factor: People”). • Training measures and knowledge Without education and training, nothing works! With training and knowledge transfer, employees are enabled to understand and perform their new roles in the changed system environment. SAP unfortunately does not have the reputation of being particularly intuitive to use, so you should not underestimate the effort involved in this area. It is hard to make time for training, despite the day-to-day demands of the job. But this investment always pays off. • Cost savings and process improvements Try to ensure that the whole team identifies with the project objectives and feels responsible for the changes/savings to be achieved. The ultimate goal is to achieve productivity gains and therefore cost savings through process improvements. The reasons for carrying out a transformation project can be very different: • You want to set yourself apart from your competitors, for example, by signifi- cantly reducing the delivery times for your products. • Your company must adapt to changing market conditions because you want to operate globally. • Through acquisitions and/or sales of business units or mergers, you need to make organisational changes, which in turn require adjustments in your ERP landscape. • You want to implement cost-cutting programmes and therefore need standardised and harmonised processes in order to be able to relocate administrative tasks to more cost-effective locations, for example. • You want to use new technologies, such as mobile applications, for your sales. • You plan to make greater use of cloud technologies. In all these cases, however, there are always major upheavals in the company, which entail the need to change strategy, process, infrastructure and organisation. These in turn have a noticeable impact on the corporate culture. Note: Nothing Works Without Change Management The changes that the project entails trigger fears and uncertainty among employees and can disrupt ongoing business operations. Ignoring this can jeopardise the success of your project. An SAP project therefore requires the sponsoring of top management to be able to successfully implement the changes in the company. Change manage- ment methods that focus on people can be used to support this. Change management is a separate sub-project within the overall project. Further information on this topic can be found in Chap. 5, “The Underestimated Success Factor: People”. 20 2 What Makes an SAP Project So Different? But tackling an SAP project also offers you the great opportunity to question traditional procedures and structures; to standardise, simplify and harmonise busi- ness processes; and to replace an outdated system architecture with modern technologies. Sponsorship from the highest management level is also necessary to be able to implement such changes within the company against internal resistance. With the introduction of S/4HANA, you will receive an integrated, modular and cross-company standard software with a wide range of functions to realise these goals. 2.2 Not All Projects Are the Same SAP Project Characteristics A project can be described as a wide variety of undertakings: from cleaning up the basement to building a new airport. However, since our book is about SAP projects, we would like to use this section to create a common understanding of the characteristics of a project, what forms of project organisation there are and who is involved in an SAP project. 2.2.1 What Is a Project? The term “project” is used today for many different situations in everyday life. For example, it may involve smaller tasks within a department for which no separate project organisation is planned or necessary. Larger projects can be pure IT projects (e.g. the creation of individual software for statistical evaluations), which are implemented by the IT department, or transformation projects, which require close cooperation between IT, business departments and management. For all projects, however, you will have to compete with other projects for scarce resources. There- fore, a new project needs good arguments to find support both from decision-makers and the workforce. You need to haveanswers to the questions of what benefits it brings, what damage it prevents and what business risks it can reduce. What is a project? A specific task is a project if we are dealing with a complex but nevertheless clearly defined problem for which there is a goal and a timeframe (start/ end) and which requires cross-departmental or cross-functional cooperation. A project is usually different from the daily business of a company. In contrast to regular tasks, a project carries a greater risk of failure and is handled in a project organisation specially set up for this purpose. At the end of the (hopefully success- ful) project, the project results are transferred to the standard company organisation (often called line organisation). Elements of a Project In the following two sections, we will briefly present the most important elements in a project: 2.2 Not All Projects Are the Same 21 • The project charter • The different types of projects • The project management systems • The project organisations • The different roles in the project • The project phases The Project Charter The project charter is the central document for the project. Make sure that your project charter contains the elements listed in Table 2.1.

Note: Templates for Download All the templates we present in the book can be downloaded free of charge. 2.2.2 What Types of Project Management Are There? Next, we would like to take a brief look at the different types of project management: • Multi-Project Management Multi-project management is characterised by the fact that several projects must be controlled and coordinated simultaneously. This can lead to resource conflicts or conflicts of objectives, for example: – Project A competes with project B for the same employee, a proven expert in her field. – While project A imposes a code freeze in the development system to perform the final integration tests, project B must continue development in the same system landscape. Typical examples of multi-project management environments are company-wide transformation projects, such as SAP projects. • Program Management A program is a bundle of related projects with a common objective. As a rule, individual, related projects are managed. For example, various individual projects can be combined for the optimisation of warehousing. • Large-Scale Project Management In principle, large-scale project management is similar to program management. Here, sub-projects of a major project are coordinated, such as in the projects “Big Dig” in Boston or the “California High-Speed Rail”. These two examples alone illustrate the challenges that large-scale project management can bring with it. • Project Portfolio Management Project portfolio management is used to manage a company’s projects, including those that do not belong together thematically. The task of project portfolio management is to consolidate key figures of all projects of a company. In this way, it provides the management with a basis for making decisions on the prioritisation of tight investment budgets (which project promises the greatest benefit for the company?) as well as cross-project information on the status of the total stock of projects. Project portfolio management is a permanent task of all organisations. 2.2 Not All Projects Are the Same 23 Project Management System If you want to establish project management in a company, certain basic conditions are required, which are mapped in the project management system. Many parts of the project management system are independent of the type of project and concern general project tasks such as: • Determine personnel requirements. • Ensure transparency of the project structure. • Adjust planning if necessary. • Create conditions for systematic project monitoring and project controlling. • Monitor the achievement of the project goals. Ensure effective, complete and timely communication to all key stakeholders Other parts are more specific to the type of project, such as clearly defined project implementation phases or technical requirements identification. A project manage- ment system helps you to keep your projects under control. Project Organisation When we talk about project organisation, we mean the combination of organisational forms and regulations to handle specific types of projects. You can choose between several project organisations, depending on the type of project: • Pure project organisation Pure project organisation is particularly suitable for large projects that require cross-company and cross-organisational control, e.g. a large-scale SAP imple- mentation project. The project goals and timeframe are clearly defined. The project employees are released for the duration of the project and report to the project manager. There are clear competences and responsibilities and short communication channels. One of the possible disadvantages could be problems with reintegration or with the transfer of the project results to the line organisation. Figure 2.1 shows a pure project organisation as it is used for critical transfor- mation projects such as SAP projects. The project staff from the purchasing, sales, production and finance departments report to the project manager of project A. • Functional project organisation The tasks or the specific project is integrated into the line organisation. This is usually recommended for less complex tasks. One department assumes responsi- bility for the project and coordinates with other departments and divisions. The responsible employee from the leading department has a coordinating task with- out authority (therefore, he/she is usually not called “project manager” but “project coordinator”). Employees are usually not fully assigned to the project. Figure 2.2 shows a functional project organisation for small projects with low priority. The financial officer responsible for project A has a coordinating role and no authority to issue instructions. 24 2 What Makes an SAP Project So Different? • Matrix project organisation A characteristic feature of this project organisation is the clear structuring of project tasks, which can also be processed separately. In most cases, these are projects of small to medium complexity. The knowledge required for the project is available in the specialist departments. The project manager has a strong formal position in the company and is responsible for the implementation of theproject. The employees of the specialist departments have two different reporting paths: although they are technically assigned to the project manager, their reporting path remains in the line organisation. Figure 2.3 shows a matrix project organisation for projects of low to medium complexity.

His task is to ensure coordination between the various functional representatives. The decision-making authority is vested in a superordinate body, such as the management. The tasks of the project staff members can be performed independently of each other. The project staff members are not exclusively released for the project. The project manager has a high level of professional competence and has a strong position in the company, usually reporting to executive or even top-level management. Figure 2.4 shows a staff project organisation for small- to medium-sized projects. The staff member responsible for project A has a high level of profes- sional competence and, as he/she is reporting directly to top management, has a strong position in the company. He has a coordinating task in the project without formal authority. The project manager derives his power from a superior author- ity, e.g. the management. Depending on the corporate culture, however, we very often find mixed forms of these project organisations in practice. Note: Make Sure You Use the Right Project Organisation! Choosing the right type of project management is a decisive factor for the success of your project. In general, the more disruptive the desired change will be, the stronger the project management type must be. As a project manager, you are largely powerless in a line project organisation and merely implement the specifications of your manager. In a matrix organisation, you as a project manager have more decision-making powers but are still dependent on the cooperation of the contributing departments.

As a project manager, you have your own employees and your own budget. You have a greater degree of freedom in making important decisions and setting the course. However, they are still dependent on the support of the line organisation’s departments and should therefore closely involve important stakeholders/decision-makers in the proj- ect. It is advisable to establish a steering committee consisting of representatives of the line organisation, which regularly evaluates the progress of the project and makes strategic project decisions. This also facilitates the handover of the project results to the line organisation at project close.

What important roles do we find in projects? We will now introduce you to the people involved in SAP projects, who will also play a role in the next chapters. The Project Manager First of all, we have the project management, which is responsible for operational project management. That’s right; that’s you! As a project manager, you lead the project team as well as the specialists (usually called “SME”, subject matter experts) and manage the operative project processes. The requirement profile for you is therefore quite demanding. You should of course have experience in project work and be familiar with the project management tools. Other important requirements are soft skills, leadership skills, stress resistance and an “eye for the big picture”. Last but not least, you should have the ability to persuade, possess assertiveness and have good communication skills. Quite a tall order? Don’t worry; by the time you have read this book, you will have sufficiently trained these qualities and come a good deal closer to the ideal project manager. Nevertheless, project management is like learning to swim—you don’t learn it by standing at the edge of the pool; you only learn it by jumping into the water and experiencing it hands-on. To find out what skills a project manager should have, see Sect. 5.2, “The Importance of Project Management Leads”. Note: Coaching/Mentoring for Project Managers Find a coach and/or mentor who will be available to you as a sparring partner and feedback provider. A coach acts as a neutral, critical discussion partner who helps you to develop new perspectives and offers suggestions for self- reflection. A mentor, on the other hand, is an experienced advisor who supports you with his/her expertise and personal contacts in dealing with your tasks. The Project Team The project team—your task force—should be characterised by a high level of professional competence, the ability to work in a team and a high degree of self- discipline and self-management. Give your team time and opportunity to come together as a team. More information on choosing the right team for your project can be found in Sect. 5.3.2, “How to Select the Right Employees”. The tasks are performed within the framework of predefined standards and tools for business processes and technical infrastructure (see also Chap. 9, “Project Support Tools”). Monitoring the execution of the project plan is performed by a project office, the project management office (PMO). You can read more about the ideal structure of the PMO in Sect. 6.1, “Support Whenever You Need It: The Project Management Office”. 28 2 What Makes an SAP Project So Different? The Project Sponsor The project sponsors for the project are responsible for providing resources, setting strategic priorities, budget adjustments and, if necessary, setting deadlines. The sponsors are also represented in the steering committee, which has the final decision-making authority. A good connection to the sponsor is therefore very important for you as project manager! The Business Process Manager The business process managers who are responsible for partial or total process flows in the company, e.g. for the entire order processing logistics, can help you to control the request process. This responsibility is a management task and is usually performed by upper management hierarchies. You must formally agree to the catalogue of requirements and the ongoing changes during the project phase (change control), so make sure they are on board in all project phases! The business process manager is also the final decision-making authority regarding process issues that affect his/her area of responsibility. The Key User The business process manager issupported by specialists, the key users (SME, subject matter expert), who are the actual process experts. The business process manager also has the important task of formally releasing the selected business scenarios for test activities and approval for production start. Project Phases Last but not least, the project is divided into sections, the project phases. Each phase contains a number of activities with expected results, which are managed and controlled by the project management. As a rule, project phases end with milestones or defined exit criteria, the achievement of which is a prerequisite for entering the next phase. In project management literature, we find different models and designations for the individual project phases; however, the difference in content is fairly small. It is always about activities for project preparation, definition, implementation and control as well as the start of production (“go-live”). Figure 2.5 gives an overview of the phases of a project. These are reflected in the Activate methodology used by SAP, the topic of Chap. 3 “The SAP S/4HANA Project: How It Should Be”. 2.3 Digitalisation in Project Management Digitalisation means new challenges for project management. In its original form, digitisation refers to the conversion of analogue values into digital formats and their processing or storage in digital technical systems. The term “digitalisation”, how- ever, is used to refer to digital change, the digital revolution or digital transformation, meaning the increasing adoption of digital technologies. With big data, cloud 2.3 Digitalisation in Project Management 29 computing or even Industrie 4.0 (also called the “Fourth Industrial Revolution”), artificial intelligence and more complex systems also come into play. Extensive volumes of data have to be processed and analysed in ever shorter time. Proven processes and traditional ways of communication are changing. Digitalisation affects all areas of life, such as the economy, society, work and private life. For example, 10–15 years ago, it was still unimaginable to monitor the birth of calves with the help of digital aids. It is now possible to transfer measure- ment and movement data, such as body temperature, drinking and eating behaviour from the rumen of the cows directly to a smartphone. For this purpose, the cows carry a small tracker in their fore stomachs, which transmits all important data to the farmer. It is a “win-win” situation for the farmer but also for the cow, where the risks of birth can be reduced by using the tracker! Whereas with analogue processing of the measured data, the farmer has to note the data on a piece of paper, which is time- consuming, digitally generated data not only can be captured much faster but also can be processed, stored and distributed directly. Modern information technologies, such as smartphones, computers, databases and mobile applications, make this possible. 2.3.1 How Can Project Management Benefit from Digital Transformation? Collaboration Project management processes can benefit from the use of digital tools in different ways. Digital tools have already supported projects in the first decade of the new millen- nium. Think of central repositories and document stores, or even messengers such as Microsoft Teams or Slack for easy and fast communication around the globe. Even then, however, the great challenge was to distribute information in a goal-oriented manner and not with a watering can. To process hundreds of unnecessary e-mails per day is not very effective. However, the requirements, especially in large international 1 2 3 4 5 6 Discover Prepare Explore Realise Deploy Run High-level project scope, solu�on selec�on and project approach Project ini�a�on, form project team, finalize plans and start the project Map project scope to solu�on, perform fit-gap analysis and define gap closure ac�vi�es Incrementally build and test integrated system environment.

This makes it all the more important to develop a concept and establish an efficient structure for the efficient distribution of relevant information. Each project member should receive the information that he/she really needs for his/her tasks and that is important to him/her and be spared from receiving (large amounts of) information that bears no relevance to his job. The focus should not be on a hedging mentality but on responsible and independent action. Digital tools make it possible to network project staff and specialist functions in real time using computers and mobile apps. This can also enable the connection of external partners. Personal responsibility, teamwork, specialist knowledge and also social and cultural skills, especially in global teams, are important factors for success. Important decisions can be made more quickly and with higher quality, thus avoiding costly wrong turns in the project. Especially in the time of a worldwide coronavirus pandemic, we are experiencing how online tools can be used to facilitate the daily work in projects. Project staff working in a home office can work very efficiently with other team members internationally, calling into question the need for a central project office location. The current project status can be viewed by all those involved at any time. Notepads are replaced by to-do lists. Everyone can see which tasks are currently in progress or already completed. We would like to take a closer look at a few tools in this context. • Slack (the name stands for the backronym Searchable Log of All Conversations and Knowledge), recently acquired by one of SAP’s main competitors Salesforce, is a collaboration software to support team communication. Teamwork takes place in so-called channels. Team members can join or leave a channel as required. Projects or teams can be assigned to a channel. Documents can be exchanged within the team. The information gets to those employees who really need it. Endless long e-mail threads with huge distribution lists are a thing of the past. All messages, documents and tools are visible in one place for everyone in the channel. • Microsoft Teams is a competing product to Slack and enables people to work together on documents in a virtual space, with the emphasis on chat room functions and video telephony. In addition, other Microsoft 365 products are integrated, such as Outlook, PowerPoint or SharePoint. The tool can also be used on smartphones. According to the manufacturer, Microsoft Teams will replace the popular telephony and chat software Skype for Business “over time”. • Confluence is a Wiki software used in companies and organisations for commu- nication and knowledge exchange on the basis of a central platform. The contents of an online lexicon can not only be read but also be edited. • MindMeister is a web-based tool on an app that supports the brainstorming process. Employees who are not in the same room but in the home office, for example, work via a virtual mind map (instead of flipcharts or similar). • Trello enables the assignment and management of tasks of a project in so-called boards with cards. The status of the individual tasks is visible to all team members via the maps. Each map contains a task, which is provided with descriptions, 2.3 Digitalisation in Project Management 31 deadlines, checklists, attachments and evaluations. Communication via e-mail is no longer necessary, as the tasks are used to communicate directly with team members in Trello.A single Trello board provides an overview of all details. Appointments can be easily set in the calendar view. • Doodle is the most well-known web-application for scheduling meetings. Every- one knows how long it can take to coordinate an appointment with all relevant parties. The employees choose a topic, suggest a date and in a few minutes create an online survey of all participants. This is much easier and saves time than tediously coordinating proposed dates with an e-mail or in numerous telephone calls. It is similar to an online questionnaire, where various selection options can be clicked on. • Toggl is a modern time management tool. With the help of the time-tracking function, you always have an overview of how much time you have spent on tasks, whether for private or professional matters. You can see the time spent on a specific project. There are also reports on the time spent at certain time intervals. • Clickup is a project management tool particularly suitable for internationally operating teams. It supports the coordination of teams working in different locations. Priorities for tasks, responsibilities and deadlines can be assigned. Different tasks can be assigned to different projects. • Google Drive can be seen as a combination of cloud-based file storage and office applications such as Google Docs, Sheets, Slides and Forms. Spreadsheets, presentations or even documents can be created and edited together in the cloud. • MURAL is a cloud-based digital whiteboard that allows you to share notes, pictures, drawings, videos, etc. in a virtual team. The goal is to enable collabora- tive design thinking and collaboration despite different locations, time zones and working hours. Monitoring in Daily Project Business Whereas in earlier projects, quality and progress reviews were usually carried out at previously defined points in time (e.g. after critical milestones or even after comple- tion of project phases), today special project management software can be used for ongoing monitoring. This means that all project staff can access the information relevant to them at any time. The evaluation of project data with the support of big data applications enables precise problem analyses. With big data, information from different sources of the project can be merged into uniform reports that can be viewed by all project members. Undesirable developments in the project can thus be recognised at an early stage, and countermeasures can be initiated. Project manage- ment tasks of the project management offices are supported by digital assistants and in some cases are completely taken over. Control of Funds and Resources Cloud services or software-as-a-service (SaaS) services help to keep project costs under control. Complex processes can be analysed in detail, and comparable data can be used for support. 32 2 What Makes an SAP Project So Different? While the new digital possibilities offer the chance to implement several projects at the same time, there is also the danger that the quality of the project work will deteriorate due to too many projects in parallel. This is particularly true for internal projects. Here, it is important to take countermeasures and find the right balance in order to avoid resource conflicts within the company. Priority setting with flexible multi-project management is required here, starting with the question: which project has the greatest benefit and is implemented first? Sufficient resources are then allocated to this project. The number of projects is reduced to what is feasible, according to the motto: “Stop starting and start finishing!” Digitalisation Competence Digitalisation competence will be of crucial importance for the future competitive- ness of companies and countries. A study of the European Investment Bank (EIB.org) shows that European firms currently lag behind in adopting digital technologies. Yet, digitalisation is clearly associated with better firm performance: Digital firms tend to have higher productivity than non-digital firms, have better manage- ment practices, be more innovative, grow faster and create higher-paying jobs. Digital adoption rates in the EU are lower than in the US. Only 66% of manufacturing firms in the EU, compared to 78% in the US, report having adopted at least one digital technology. The difference is particularly large in the construction sector, where the share of digital firms is 40% in the EU and 61% in the US. The difference in adoption rates between EU and US firms is 13 percentage points in services and 11 percentage points in the infrastructure sector. When focusing on the share of firms that have fully organised their business around at least one digital technology, the EU is lagging in particular in the construction sector (5% compared to 17% in the US) and the infrastructure sector (15% compared to 20% in the US). 2.3.2 From Classical Project Management to Agile Processes (Methods) It is therefore no surprise that digitisation is also changing the processes and procedures in IT project management. The effects concern not only the project managers but also the project teams and the entire approach to a project. Decisions can no longer be made by a project manager alone. Experts from the various corporate divisions must be involved as advisory bodies. We see a trend in many companies to avoid large projects if possible and instead carry out a larger number of smaller, time-limited projects: long-term projects with fixed objectives become the exception. The scope is becoming dynamic. Sub-objectives are dynamically adapted to new challenges during the project duration. Classical project management methods, such as the waterfall method, are supplemented by agile procedures. 2.3 Digitalisation in Project Management 33 http://eib.org Manifesto for Agile Software Development The term “agile” was already used in software development in the early 1990s. In February 2001, 17 IT experts then formulated the “Manifesto for Agile Software Development” with the following principles, which are still valid today: • Individuals and interactions over processes and tools • Working software over comprehensive documentation • Customer collaboration over contract negotiation • Responding to change over following a plan The thought patterns of information technology form the basis here. A problem is approached in a structured way and from a logical perspective. Complex topics are broken down into individual parts and reduced to core elements. Through abstrac- tion, the problem is viewed holistically and led to the solutions step by step. The results of partial, hands-on tests are the basis for the next steps. Each step is reflected in the teams, and possible improvements are implemented immediately. Scrum A good example of this is “Scrum”, which has become an established standard for project management in software developpment. The approach no longer corresponds to the old model of giving employees precise instructions on how a problem is to be solved. With Scrum, teams are put together for a task in a cross-functional way. How the goal will ultimately be achieved is left to the team to figure out. This also means delegating more responsibility to decentralised pools of experts. It is important to pay attention to a clear communication structure and rules. The “Scrum” approach is described in more detail in Sect. 2.3.3, “Hybrid Project Management”. There are also good examples of this in the automotive industry. At Daimler, for example, project management for product development has been transferred to a so-called swarm organisation. Some of the employees are no longer subject to a rigid hierarchy but collaborate with one another on specific topics, similar to a startup. Agile Approaches and Practices While the agile approach can undoubtedly bring many advantages, it is also worth- while to look at it from a different angle. The “Swiss Agile Study 2012” (Agile Software Development in Switzerland, Prof. Martin M.Kropp, FH Nordwestschweiz, Windisch; Andreas A. Meier, Zurich University of Applied Sciences, Winterthur) shows in this context interesting results compared to classical processes in software development. According to the study, the aspects of software maintenance/extensibility and software development costs remain unchanged or have deteriorated, in some cases considerably. On the other hand, the aspects of the following have improved: 34 2 What Makes an SAP Project So Different? • Adaptation to changing priorities • Development processes • Market readiness • Consistency between IT and business objectives • Benefits and visibility of a project • Team morale • Requirements management • Productivity • Risk management A company survey from 2011 with approx. 800 people comes to similar results, with 1/3 of the companies employing between 100 and 1000 employees. The survey was conducted by the Bremen University of Applied Sciences, Bremerhaven, the Cologne University of Applied Sciences, ANECON Software Design und Beratung GmbH, the German Testing Board and the Swiss Testing Board. The result shows that in principle there is no difference between agile and non-agile developed software regarding software errors in daily operations. In summary, there is not one correct approach for all situations! Many projects are certainly suitable for an agile approach, but this does not mean that the classic project management method (e.g. the waterfall method) should no longer be used. Classic project management is characterised by long-term plans and processes. The project manager distributes the tasks and, in many cases, has the needed expertise. The situation is different with agile project management. The responsibility lies where the expertise is. But that does not mean that there are no structures and no leadership in the agile approach. The Scrum Master is responsible that the team follows the structures. The “classic” manager does not exist in Scrum! An interesting approach is the combination of agile and classic techniques in so-called hybrid project management. We will deal with the details of this method in the next section. 2.3.3 Hybrid Project Management The classical approach, using the “waterfall method”, still has its right to exist if the underlying mechanisms are properly understood. Detailed project documentation is also helpful for new project members—and of course the organisation taking over after project completion. In hybrid project management, the methods of the classical approach are com- bined with agile elements. The aim is to combine the advantages of both methods in one project, thus saving time and reducing project costs. In this section, the neces- sary framework conditions for a functioning “hybrid project management” are discussed. 2.3 Digitalisation in Project Management 35 Project Goals and Catalogue of Deliverables First of all, the project objectives and the catalogue of services must be defined by the project manager, who is responsible for the entire project. The service catalogue contains elements that are clear (linear processes such as training or marketing) and elements with a certain degree of uncertainty (nonlinear processes such as software development). For the linear processes, the waterfall method can be used in princi- ple; for the nonlinear elements, the agile method is preferred. The project manager should be able to assign the individual elements to the method that is most suitable in each case. Last but not least, the project manager should draw up a risk mitigation plan for both methods as part of the project risk management. Project Roles A central aspect of project organisation is the definition of project roles with associated task areas, decision-making powers and responsibilities. It is important to define the roles so that there are as few overlaps and gaps as possible. Overlaps may lead to fights over competence, and if project tasks are not assigned to a project role, there is a risk that these (possibly critical) tasks will not be performed by anyone. The key roles are as follows: • Product Owner The product owner can be either the project manager or product manager. He/She is the link between customers and/or stakeholders and the Sprint Teams and is responsible for prioritising requirements. • Scrum Master The Scrum Master can also be the project manager if he/she is familiar with the agile processes. He/She leads the sprint meetings and ensures that the time targets for the individual process steps are met. However, the Scrum Master has no formal leadership function. • Sprint Team The Sprint Team estimates the effort for the tasks at hand and is responsible for development and testing. Ideally, the Sprint Team, including the product owner and the Scrum Master, should not be larger than seven people to ensure fast decision-making processes. The team consists of developers, testers, architects and technical experts. In addition, it is recommended to include subject matter experts (SMEs), who understand the business processes and will be the future users, in the team. Each team member knows the overall goal of the project. Conclusion If a process is too complex to use the waterfall method, it is more effective to use the hybrid approach, which is essentially a combination of the waterfall and agile approach. 36 2 What Makes an SAP Project So Different? At the end of the day, the advantages of the hybrid approach are that it offers greater flexibility in rapidly changing situations. In addition, by detecting errors earlier in the development cycles, costs can be reduced, and the team can continu- ously improve during development. Finally, close communication with stakeholders during development is also beneficial for the acceptance and quality of the project results. 2.4 Why Software from SAP? In the following section, we’ll discuss the criteria you should apply and the steps you should follow when you decide if you want to implement S/4HANA and possibly other SAP products. These steps and criteria are independent of any particular software version. 2.4.1 Analysis of the Initial Situation The IT strategy and the decision for an ERP system based on the strategic considerations and goals in general guide the future development of the company. The company strategy and the IT strategy, which form the basis for business operations and future development, are derived from these. These frameworks form the foundation, as well as the guardrails, both in terms of content and organisation, for the SAP project. Next, we’ll outline how these individual strategies influence the SAP project: • Corporate strategy The corporate strategy sets the fundamental frame of reference for all strategic decisions, including the SAP project. It answers questions regarding the purpose of the enterprise, how to differentiate from the competition and implicitly “what not to do”. • IT strategy Based on the corporate strategy, the IT strategy defines the implementation of business processes on an IT platform. The IT strategy may need to be reviewed, when the corporate strategy is changed or updated. • ERP strategy The ERP strategy is an essential part of the IT strategy (alongside, e.g. strategies for IT security, IT infrastructure and IT operations) and deals with one of the core components of a corporation’s IT: the selection, implementation, operation and further development of a company’s ERP solution. In the following, we show you examples of how a company’s IT and ERP strategies influence the choice of ERP software. 2.4 Why Software from SAP? 37 2.4.2 Example for Selecting an ERP Software Let’s assume we are in a globally active company in the service industry with independently operating national subsidiaries. Over the years, a heterogeneous software and IT infrastructure landscape has developed within the group, which drives the overall IT costs in the company to levels that are no longer sustainable. Identical business processes are supportedin the national companies with different software solutions. For the most part, these are in-house developments which are expensive, difficult to integrate and complex to maintain. Global Consolidation as a Challenge Each national company has its own IT team, which is responsible for implementing the requirements from the business departments and for ongoing operations. The global consolidation of business figures for the monthly, quarterly and annual financial statements is therefore a nightmare and keeps numerous employees busy for weeks. There are always cautious approaches to harmonising processes and systems across countries, but without much of an impact. Killer arguments such as “Our processes are particularly specific to each country and if we change them we lose sales” have long been heard by the company management. However, declining sales, increasing cost pressure and declining profitability are now leading to a rethink in management. 2.4.3 Review of the Existing System Landscape To avoid rushing into a strategic decision like this, it is first necessary to carry out an inventory. Conduct a thorough review of the existing system landscape in order to find out what improvements can actually be achieved by a new software solution. Back to our example, “A new broom sweeps clean” is not only an often used but also a fitting saying. In our project, a change of the chief information officer (CIO), the head of IT, is intended to turn things around. As a first step, the new CIO, Mr. Smith, will conduct IT reviews in the national subsidiaries to get a comprehen- sive picture of the situation: a selection of IT and process specialists from the company is sent on a mission to examine the IT systems of all the country operations in detail. Contents of the Review The agenda and questions for the reviews are set by the CIO and his team with the following content: – Actual system architecture and infrastructure environment – Ongoing application support of business processes – IT resource situation – Total IT costs – Local IT strategy 38 2 What Makes an SAP Project So Different? The reviews are carried out with the local IT management, the business process managers, the finance department and a representative of the local management. The results of the reviews are sobering: the CIO’s first impression that each country organisation does its own thing and drives its own process and IT solutions is fully confirmed. It quickly becomes clear that things cannot go on like this. The problems in the business development of the national companies also lead to a realignment of the organisational structures in the company, from a strongly decentralised to a more centralised form of organisation. This means that responsibilities and tasks which were previously performed by the national companies are being transferred to the head office. This is a further piece in the puzzle on the way to an overall corporate IT strategy. Mr. Smith can convince the management board that there is a need for action and he is authorised to develop an overall IT solution for the company. 2.4.4 The Assessment: Conducting an Analysis of the As-Is Situation To become competitive again in the global markets, company management takes several measures. An important step towards achieving this goal is the standardisation and harmonisation of business processes and systems for all national companies, which will also reduce infrastructure costs within the company. Draw Up Specifications To carry out an analysis of the status quo, a working group consisting of employees from the head office and the national subsidiaries is set up, which, in an effort to make those who are affected by the change, part of the change, includes both IT and process experts. The results of the earlier IT reviews can be used as a basis. In addition, a functional specification of future requirements is drawn up, which on the one hand contains the necessary consolidations and centralisation measures and on the other hand takes into account justified requirements of the national subsidiaries. At this point in time, some fundamental decisions on how to proceed have already been made. Deciding on a Standard Software The future software solution will no longer be a proprietary custom development but standard software from a provider with a good reputation on the market. For the final decision, which standard software is to be used company-wide in the future, the next step is to define additional selection criteria. 2.4.5 Software Selection Criteria The first step is to create a shortlist of eligible software providers. To do this, it is first necessary to determine the technical and functional requirements (i.e. the target 2.4 Why Software from SAP? 39 processes) for the software. This task is performed by the task force team. In this early phase, it is crucial to clarify to what extent the existing organisational structures of the group can be mapped in the new ERP system. The company management will pay particular attention to the price-performance ratio of the software, as this is a core criterion for the business case. To determine the extent to which the target processes are covered by the software in question, the functionality of the software providers must be compared and evaluated against the existing process specifications. At this point in time, a high- level comparison of the target processes with the functionality offered by the provider’s standard software is sufficient. Ideally, this task will be carried out in cooperation with the consultants of the software providers in question. Another important aspect is the comparison of the current system architecture with the target system architecture of the future ERP system. Since this task is very time-consuming due to the different system architectures in the individual market units, larger countries are examined first. The aim is to determine which legacy systems can be replaced and how many new interfaces are required for the new ERP system. For the final decision, the team uses the following general selection criteria (see Table 2.2). These criteria should definitely be taken into account when making your own software decision, and you should decide how to weigh them. The extent to which the individual selection criteria are fulfilled is then answered with regard to SAP S/4HANA. Draw up a realistic cost-benefit calculation. Proceed in a structured way: first describe the problem and the proposed solution. If you have several proposed solutions, evaluate the individual alternatives. Calculate the profitability by compar- ing the costs and savings. In addition to the hard factors, such as savings on the IT side through the replacement of old systems, personnel savings on the user side, costs for hardware purchases or software licences, also take soft factors into account: possible increases in turnover through higher customer satisfaction. Also, do not forget to point out the risks for the project. They will become the basis for project risk management. Note: High Expectations Expectations of a rapid return on investment (ROI) in SAP projects are high. Realistically speaking, success must be viewed in the long term. Generally speaking, corporate and cross-functional implementations offer the highest savings potential. Implementation Cost In our experience, the implementation costs for the new software are often underestimated for various reasons, and on the other hand, the savings are often inflated to get the project off the ground. Once the project has started, the actual costs become apparent, but that rarely leads to projects being cancelled or stopped (“sunk cost fallacy”). 40 2 What Makes an SAP Project So Different? Table 2.2 General selection criteria for ERP software Criteria Questions Market position of the supplier • How much experience does the provider have in the market? • How long has the supplier been on the market? • How safe and sustainable is the investment?• How innovative is the supplier? • Is the supplier globally active or in the countries relevant for you? Certifications • Is the supplier certified according to ISO 9001? • What other industry-relevant certifications are fulfilled? Cost-benefit analysis/business case • What are the costs for the introduction and operation of the software? • What savings can be achieved with the software? Implementation risks • What were the challenges in the reference customers’ project? • How long did comparable projects of reference customers usually take? • How many existing implementations are there in our industry? Stability/performance • Does the software run stable and performant in daily use at reference customers? Scalability • Is further growth possible without running the risk of performance losses? • Can additional modules be introduced in the future? • How will this affect the performance in daily operation? User-friendliness and language options • Is the user interface user-friendly? • In which languages and alphabets is the software available? Hotline support/helpdesk • Is there a hotline support, and when is it available? • Is there an emergency hotline for crisis situations that is available 24/7? • Are there service SLAs for restoring operability during an outage? Software maintenance/update • How long is the vendor’s mainstream maintenance? Maintenance should be guaranteed for at least 5–10 years after a new version is available • Is an upgrade path available to be able to install newer software versions without much effort? • In case of a cloud-based software (SaaS), how often are updates made available and what is their impact on operations? Support for release upgrades Are there special tools available and needed to perform a release upgrade? Data security and authorisation concept How do you prevent unauthorised changes and access to data? Data migration Are there special tools for migrating legacy data? Functionality/process harmonisation/standardisation • How high is the degree of coverage of the software functionality for the company-specific requirements? (continued) 2.4 Why Software from SAP? 41 Tip: Exchange of Experience with Like-Minded People To better assess the implementation risks, you should try to exchange infor- mation with other customers of the software vendor in your industry, prefera- bly without any of the software vendor’s representatives present. Often there are also user groups (such as ASUG, Americas SAP Users’ Group) that can offer assistance. You should also get future users on board during the software selection process. For example, arrange software demonstrations (“live demos”) using practical examples with the supplier. If possible, also take your future users to reference customers. This is a good opportunity to exchange information from user to user and to involve your employees in the project at an early stage. 2.4.6 Looking Back: Experiences with the SAP System and Potential for Improvement Back to our earlier example, once our task force team has agreed on the selection criteria, these are assessed according to their relevance. The result is then presented to the CIO, who is very satisfied with the team’s work. In addition to these, a number of technical and functional aspects as well as other criteria are often relevant to management decisions. This was also the case in the example project presented in this chapter: Table 2.2 (continued) Criteria Questions • What possibilities are there to close any gaps by extensions or modifications? IT infrastructure costs • What financial benefits/savings will the uniform system architecture offer? • What are the additional costs for upskilling technical personnel? Archiving • How can data that is no longer needed in daily business operations be archived? Cloud offerings • Can the software be operated cost-effectively in the cloud? WRICEF: workflows, reports, interfaces, conversions, forms What functional scope does the software offer in the area of workflows, i.e. partial process automation, report generation, interface types, data transfer and forms (print products)? RPA, AI, blockchain, IoT Which offerings in the areas of robotic process automation, artificial intelligence, blockchain and Internet of Things are included/available with the software? Experience data vs. operational data How can customer experience data be mapped to operational processes performance? 42 2 What Makes an SAP Project So Different? • Uniform data model With the help of a uniform integrated data model, it is possible to make company group-wide decisions quickly and efficiently. Master data and interface problems are avoided. • Improved data quality Cumbersome and lengthy data consolidation from the legacy systems of individ- ual national companies is no longer necessary. The quality of the data used for corporate management has improved significantly. • Harmonisation of business processes The group’s business processes are being harmonised worldwide, supporting the plans to centralise operational units in more cost-effective locations. Customer satisfaction will be enhanced by the uniform processes, as lead times from receipt of order to delivery (and ultimately receipt of payment) are substantially reduced. • Lower infrastructure costs IT infrastructure costs are considerably reduced by a uniform system architecture. New business models can be easily supported and implemented. The implemen- tation risks are relatively low, and the system is stable. • Usability Various reference customer visits have shown that the user-friendliness of the application meets the requirements. • Investment security As the ERP market leader, SAP offers the best prerequisites for a long-term partnership: SAP has been developing business software for 50 years and is one of the world’s largest software manufacturers with a huge number of successful implementations in a variety of industries. Taken from Project Life In addition to the technical and functional aspects, in our example project, the expenses and savings calculated in the cost-benefit analysis are once again aligned with the finance department and the affected functional and departmental managers. Nonetheless, it is to be expected that the selection of the new ERP software will lead to passionate discussions at the board meeting. And this is how it happens: the CIO has invited a technical and functional representative from the task force team to support the meeting. The meeting agenda includes 60 minutes for this topic—an ambitious time schedule for a decision that will mean significant changes for the company and impact its future for years to come. Green Light for the SAP Project Thanks to the good preparation of the team, the meeting went as expected: apart from a few points that were not relevant to the decision, all open questions were answered satisfactorily. The biggest point of contention is the cost-benefit analysis calculations, which promise to reach the break-even point only 4 years after the introduction. At this point, it becomes clear just how important it was to closely coordinate with the finance department and functional representatives. With good 2.4 Why Software from SAP? 43 arguments, the management board can be convinced that the planned introduction of standard SAP software within the group is the right way forward: green light for the SAP project! Tip: Careful Preparation Is Crucial for Important Decision-Making Meetings Our experience is that the outcome of important decision meetings depends largely on preparation. This includes the preparation of the relevant documents and, above all, contact/coordination with key decision-makers and stakeholders before the actual meeting. Only if the proponents and opponents, as well as their views and concerns, are known in advance is it possible to compile the materials for the decision meeting in a targeted manner. Pilots To minimise the risk, a pilot should precede the worldwide rollout.The CIO will be responsible for the installation, with the guidance to approach the proposed rollout dates aggressively and, if possible, to complete the pilot earlier than planned. The project is thus already under pressure before it has even started. In this difficult situation, the project management injects a dose of realism and underpins the top-down deadlines with solid bottom-up planning. If this shows that the planned introduction dates cannot be met with the best team in the world, a change request is inevitable. Our recommendation is to tackle this issue, which is unpleasant for all parties involved, in a timely, constructive and fact-based manner early on and not to put it off for later. Retrospective Following the successful implementation and subsequent worldwide rollout, 13 years have now passed. In summary, it can be said that the expectations have been largely fulfilled. IT and personnel costs have been reduced; the harmonisation of global processes has brought considerable progress in productivity; customer satisfaction, especially from internationally operating customers, has increased; and sales have risen considerably. Potential for Improvement However, when several companies were acquired during the implementation project, it was not possible to avoid including third-party programs to accommodate the expanded business portfolio. This increased the complexity and the maintenance effort. It was discussed if it would make sense to merge several ERP systems into a new uniform system. The considerable memory requirements of transactional processing in the various SAP systems increasingly became a problem. For fast decision-making, real-time data processing is a prerequisite, which is not possible with the previous systems. In the same way, one would like to take advantage of the opportunities offered by digitalisation with a future-oriented IT architecture without losing the previous investments in the SAP systems. A further aspect to be 44 2 What Makes an SAP Project So Different? considered is the duration of the maintenance commitment from SAP for the existing SAP system. As things stand today, the maintenance commitment for SAP Business Suite 7 has been extended from 2025 to the end of 2027 due to considerable pressure from major customers. A further extension until 2030, an additional cost is possible. Nevertheless, the journey to SAP S/4HANA will be a major challenge for the company. Our recommendation is to start this journey in 2021 to be able to exploit the advantages of the new technology to maintain a competitive edge. 2.5 The Road to SAP S/4HANA There are different scenarios on the way to S/4 HANA. Many criteria that we have already considered when introducing a new ERP solution also apply here. Today, many corporations find themselves in one of two fundamentally different starting situations. 2.5.1 Your Company Has Been Using SAP for Years For a great number of customers, the first wave of transformation, process and organisation optimisation, which took place within the framework of the SAP introduction, is already “water under the bridge”. They have already mastered the fundamental business transformation which went hand in hand with the introduction of SAP (ERP/Business Suite) years or even decades ago. The business departments now have in-depth SAP process know-how, and in the IT department, years of SAP operating experience are available. The challenge for you is you have already been using your SAP software for years or even decades and have successively adapted it to your requirements. What, besides the looming end of mainstream maintenance, is the business case for S/4HANA? After the initial introduction, functional enhancements were implemented in the following years either on your own or with the support of partners (whose experts are usually no longer available). The list of extensions—and in the worst case modifications—has become longer and longer, so today hardly anyone understands it all. In many companies that have been using SAP for years, SAP systems resemble an onion with many layers: changing business requirements lead to numerous extension and adaptation projects over the years. Many are successful, others less so, but all leave their (development) traces in the system landscapes. The documen- tation is partly available, partly outdated but often incomplete. A distinction between “this is needed” and “this needs to be cleaned up” is difficult, and therefore, calls for consolidation projects are unsuccessful. For lack of demonstrable business benefit, these projects are a “hard sell” to the management within the company anyway. The main thing is that the systems work. Rising Operating Costs But the operating costs for this grown system landscape are increasing: every new release requires extensive testing, as the effects on other areas can no longer be 2.5 The Road to SAP S/4HANA 45 reliably estimated in advance. Checking and adapting to extensions and modifications costs a lot of time and money. “Never change a running system” is the motto, but the clock is ticking. Older SAP software versions run out of support, S/4HANA and cloud offers from SAP beckon with new functionalities and potential cost savings. Perhaps the competition is faster and achieves competitive advantages by using new solutions. The change from SAP ERP/Business Suite to S/4HANA offers the opportunity to use the new in-memory architecture to design completely new, considerably more efficient processes and possibilities for your own company. The key question is how to make the switch to this fundamental new technology: clean cut or evolutionary development? What moves to the cloud? What remains on-premise? Analysis of Existing Processes The possibilities of digitalisation, the use of artificial intelligence (AI) in companies and the increasing competitive pressure in a global market environment require a detailed analysis of existing processes. The following questions should be asked: • Can I develop new business areas with my existing processes? • Do I need to harmonise my business process? • What about my IT system landscape? • Is all the data I need for business management on a uniform system, or is the data managed in different, disjointed systems? • Is it possible to process large amounts of data in real time? • Has the IT infrastructure that has grown over the years, become too complex and expensive to operate? • Can I react quickly to changes in the market with my existing processes and systems? • How long is the maintenance of my existing SAP infrastructure still guaranteed by the manufacturer? If you have already dealt with some of these questions or can answer some of them with “yes”, it makes sense to consider the advantages of SAP S/4HANA technology. Whether it is a new SAP implementation, a conversion of an existing SAP ERP system to SAP S/4HANA or a consolidation of several SAP ERP systems into “one” SAP S/4HANA system, the same principle applies to all scenarios: we are dealing with a transformation project that has to be located at the highest level in the company. For both variants, this is the opportunity to adapt the old processes as far as possible to the standard of the new, simplified S/4HANA processes. A new implementation may also make sense in an existing SAP landscape, but you must weigh carefully whether such a path is the right one. 46 2 What Makes an SAP Project So Different? 2.5.2 Your Company Is About to Introduce SAP for the First Time Over the years, SAP has achieved enormous market penetration. Today’s net new SAP customers are usually relatively young companies that have grown steadily in recent years and are now reaching the limits of their existing IT systems. SAP, as the world market leader for business software, is usually introduced to replace a whole slew of smaller IT solutions and thus enable further growth. Problems with different master data, system breaks and a multitude of interfaces make life difficultfor these companies. They are concerned with standardising their IT landscape, eliminating island solutions, reducing IT costs and using new technologies. The IT landscape has not kept pace with the rapid development of the company and is in dire need to be transformed from a millstone around the company’s neck into an innovation driver and “enabler” for new offers and services. These young, dynamic companies are very open to cloud solutions but soon find that their requirements for business software in the cloud cannot be mapped as easily as an office package in the cloud. Understanding the complexity of SAP software and the breadth of its offerings and being able to assess what you actually need are serious challenges. You can expect a relatively steep learning curve, as staff usually lack SAP solution architects, i.e. experts with broad and detailed SAP know-how who can translate business requirements into a flexible, cost-effective and future- proof IT strategy. This kind of expertise usually needs to be brought in for the development and implementation. Having an experienced solution architect, who designs the SAP solution, is a key success factor. Even at this early stage, the question arises: do you ultimately operate your SAP solution yourself? Do you turn to a hosting partner or one of SAP’s PaaS or SaaS offerings? Or do you try to use cloud products as much as possible to keep your IT expenditure low? After all, S/4HANA offers all these variants. 2.5.3 SAP S/4HANA Usage Models The first question is how to operate SAP S/4HANA in the future. In the following section, we will discuss the different usage models for S/4HANA operation in more detail (see Table 2.3). Table 2.3 SAP S/4HANA usage models Deployment Product Name License On Premise S/4HANA on Premise Perpetual Licensing SAP’s PaaS Cloud (HANA Enterprise Cloud) S/4HANA on Premise Bring your own License (BYOL) S/4HANA PCE (Private Cloud Edition) Subscription S/4HANA Cloud, extended edition Subscription SAP’s SaaS Cloud S/4HANA Cloud Subscription 2.5 The Road to SAP S/4HANA 47 S/4HANA On-Premise System (Local Approach) SAP S/4HANA on-premise is the new Intelligent Suite based on the in-memory database HANA. In this model, operations run in the company’s own data centre and on its own servers or are operated by an infrastructure/application hosting provider. The entire IT infrastructure, such as hardware, applications, operating system, middleware, network and HANA database, is managed by the customer or the hosting provider. The control over upgrades, customising and necessary enhancements remains in the company. The company decides on the frequency and schedule of software upgrades and support packages, within the maintenance framework given by SAP. However, this option is also time- and cost-intensive and requires trained IT personnel. We recommend this option for the following: • Industries with high process complexity Industries with high process complexity, such as manufacturing (discrete industries) and the automotive industry. Often numerous adjustments are unavoidable and can be implemented most easily in the S/4HANA on-premise variant. • Countries with limited IT infrastructure Here, it is usually not possible to set up reliable data lines with the required bandwidth to the data centre. • Customers with very high data security requirements Customers with very high data security requirements, such as intelligence services, defence and public security or customers in a country where data security is limited. Companies to which these special circumstances do not apply, have the option of switching to a combination of on-premise offering and IaaS or private cloud (PaaS) or even to purely cloud-based SAP S/4HANA versions. SAP S/4HANA as On-Premise Version in the IaaS Cloud This variant of operating the SAP S/4HANA on-premise is offered, e.g. by Hyperscalers, among others (SAP itself offers this only in exceptional cases). Customers save the investment in infrastructure, server and network but still retain full control over the landscape. From the provider’s point of view, an IaaS cloud is a “black box”, i.e. topics such as monitoring, backup/restore, etc. are only offered in a very rudimentary form, if at all. Everything that goes beyond basic availability monitoring and restores to a delivery state remains usually the responsibility of the customer. SAP S/4HANA as On-Premise Version in the Private Cloud Platform as a Service (PaaS) The SAP S/4HANA on-premise version can also be operated in a “private cloud” environment. In this case, the customer-specific system landscape runs in the SAP HANA Enterprise Cloud (HEC), which is part of SAP’s Enterprise Cloud Services organisation. This option was developed by SAP to facilitate the implementation of 48 2 What Makes an SAP Project So Different? SAP S/4HANA for customers. It emulates an on-premise environment in a cloud environment. The service is delivered as an SAPManaged Service based on a private cloud infrastructure. In this case, servers and hardware are provided by SAP—either in its own data centres or partner data centres—or at a hyperscaler (Microsoft Azure, Amazon Web Services, Google). The system landscape is managed by SAP, and the applications are operated by SAP’s own global IT teams. The standard contracts include 24/7 operation of the landscapes with SLAs (Service Level Agreement) between 95% and 99.9% and the provision of infrastructure-related services. Depending on requirements, additional services from the areas of basis and application manage- ment can be purchased in this model. Users of the SAP-HANA Enterprise Cloud pay a monthly rate that varies depending on the size of the system landscapes and the agreed SLA. EU-only team support can be provided for an additional charge to ensure EU-data protection regulations are met. The offer comprises two contract types: Bring-your-own-license (BYOL) Customers use the (usually existing) software licences in the cloud This means that they pay a one-time license fee as well as an additional annual, percentage-based software maintenance fee Subscription Customers acquire the usage rights as a “bundle” together with the infrastructure service. The one- time license fee and the software maintenance fee are included in this subscription Note: Special Maintenance Clauses in Some Subscription Models Subscription models are attractive: they relieve the cash flow because the one-off, cost-intensive purchase of licences is no longer necessary. They are predictable cost blocks, since the “rent” must be paid at regular intervals. But pay attention to the small print: • Any changes to the contract (Commercial Change Requests) during the term of the contract require—as with any other contract—the agreement of both parties. SAP does not normally accept “negative CRs”, i.e. changes that would reduce the monthly fee. • The subscription model includes the usage fee, infrastructure, operating costs and software maintenance. Should you decide to switch back to BYOL at a later date, SAP will still require you to pay the maintenance fee for the subscription period. Together with the licence fees then incurred, this can result in a very considerable sum. 2.5 The Road to SAP S/4HANA 49 Mainstream Maintenance The customers commit to operate only software versions that are in SAP mainte- nance (mainstream maintenance) in this PaaS environment. In addition, there is no obligation (unlike the following offers) to regularly install newer software versions, but there are limitations regarding OS (Linux only) and the database (SAP HANA or ASE—Adaptive Server Enterprise—a relational database acquired from Sybase). This has several advantages: – Standardisation of the infrastructure stack (DB + OS) while retaining the familiar user interface and any extensions – Cost reduction potential through the subscription models offered (“software rental”) – Possible savings on own IT personnel – Easy extension with otherSAP cloud offerings – Possibility to have the entire software stack, from infrastructure to application management, operated by SAP But the disadvantages must also be taken into account: – No customer access to operating system allowed. – Limited flexibility: Detailed description of the tasks to be performed is neces- sary—lead times for service requests are between a few hours (for automated services like system restart) and 6 days for highly complex ones. – Limited possibilities of operating third-party (non-SAP) software. – Customers still need their own SAP experts as contact persons for SAP. SAP HANA Enterprise Cloud The SAP HANA Enterprise Cloud was originally intended as an intermediate step for customers planning to move from SAP Business Suite on-premise to SAP S/4HANA in the cloud. Since the changeover from SAP Business Suite to SAP S/4HANA is a very big step for many customers, SAP offers assistance through the SAP HANA Enterprise Cloud: the technological stack is standardised (Linux and SAP HANA only), the end users retain their familiar user interfaces and processes, and the customer’s IT department is relieved of operational issues. Due to the great commercial success of the SAP HANA Enterprise Cloud, the offer was extended to include SAP S/4HANA Cloud, Extended Edition. The contracts differ in some areas from the classic SAP HANA Enterprise Cloud contracts, but the delivery model is the same. SAP S/4HANA Private Cloud Edition: The S/4HANA PCE is a new offering, introduced in late 2020, which aims to make it easier for customers currently running SAP ERP on-premise versions to move to S/4HANA. 50 2 What Makes an SAP Project So Different? It is a private managed cloud offering (PaaS), which offers an extension of the customer’s private network and integration into his private DNS and runs in SAP’s data centres, or on hyperscaler. The migration can be performed by SAP or partners and the rules for modifications and extensions the same as in the S/4HANA on-premise solution. In terms of functionality, S/4HANA PCE is also identical to S/4HANA on premise and offers the same relaxed upgrade requirements: customers must remain within SAP’s mainstream maintenance period and can choose to upgrade at any time within this framework. SAP S/4HANA Cloud, Extended Edition: The S/4HANA Cloud EE differs from the on-premise version in three main points: • Modifications are not possible (but extensions are). • SAP offers updates twice a year; customers must install at least one update per year. • The Extended Edition can only be used in SAP’s own cloud services. The S/4HANA Cloud Extended Edition can be used in the same way as the on-premise solution in the PaaS cloud (SAP HEC) but only in the subscription model. The advantages for this option (in addition to those already mentioned above) are as follows: • Customers can adopt and use the latest SAP technologies promptly. • The SAP enhancement model allows many possibilities to customise the software according to individual needs. But the disadvantage is that updates must be installed within the defined period of time—which causes expenses on the customer side. However, it can be assumed that the effort will be kept within limits, as there can be no modifications whatsoever. SAP S/4HANA Cloud, Essential Edition Software as a Service from SAP (SaaS) SAP S/4HANA Cloud is the only true “SAP SaaS version” (software as a service) of S/4HANA. It is the only S/4HANA variant with “one code line”, i.e. all customers use the same program code. The resource-intensive maintenance of different versions for SAP is thereby eliminated. Updates are automatically imported into all customer systems every quarter. Customising is only possible to a very limited extent. Extensions are possible (via BAdI, business add-ins); in addition, there are the functionalities in-app extensibility and “side-by-side development” in the SAP Business Technology Platform. These extension possibilities are the fundamentally new concept of SAP S/4HANA Cloud. Enhancements cannot—as in the past—be mapped in the ERP software but only via extensions outside SAP S/4HANA. Thus, the core of the ERP solution always remains in the standard, massively reducing upgrade efforts. 2.5 The Road to SAP S/4HANA 51 In-App Extensibility: In-app extensibility is a simple way to customise screen masks (e.g. hide fields), create new tables and fields and store them with process logic. Deep technical know- how is not required, so experienced end users (power users, key users) can create these extensions themselves. Side-by-Side Development: Side-by-side development is the method of choice for complex development projects. SAP offers an SAP S/4HANA Cloud SDK (software development kit), which, in conjunction with the SAP Cloud Platform, enables time- and cost- transparent development of complex apps. By using open APIs (application pro- gramming interfaces) and CDS views (core data services, a method of data modelling for the definition of customer-specific “views”), which are provided via OData services (Open Data Protocol), it is possible to develop apps that remain usable and unchanged despite quarterly SAP S/4HANA updates. Further Advantages: Users can use a large part of the S/4HANA functions without the hardware, databases or IT staff required for the local version. In the S/4HANA Cloud, SAP provides and manages almost the entire infrastructure for the customer. However, the flexibility for process adjustments and requirements is less than with the on-premise version. Compared to on-premise, implementation is faster because a fully tested cloud version is provided by the manufacturer on a ready-made platform. The use of S/4HANA Cloud Essentials requires a fundamental change in approach. There is no longer a familiar development environment, and there is no access to the backend. Business processes have to adapt to the given standard. At the same time, the import of new software versions is effortless (compared to the on-premise version), as it is a pure standard system. Extensions are only possible to a limited extent within the S/4HANA system—instead using the abovementioned extension possibilities in connection with the SAP Business Technology Platform. Conclusion: On-Premise Versus Cloud Version The SAP S/4HANA on-premise variant is best suited for companies that require the full range of functions with a high degree of flexibility for customisation and—if necessary—modification. As a rule, these are larger companies with complex, firmly established processes or legal requirements that are currently not addressable via SAP’s standard process framework. The SAP S/4HANA Cloud variant is particularly suitable for companies that require an agile offering that covers the most important business processes and allows a fast innovation cycle. However, customer-specific changes are not possible. Keep in mind that the infrastructure costs of a cloud solution are in most cases lower than those of an on-premise solution, where ongoing maintenance and modernisation costs must also be taken into account. With a cloud solution, 52 2 What Makes an SAP Project So Different? companies also benefit from the latest technologies and timely innovations devel- oped by SAP. Hybrid Approach: A combination of both variants is also possible. In this case, we speak of a hybrid approach. Important business processes or core processes can continue to run on local servers (on-premise), while other standard processes, such as payroll, can be operated in the cloud. Here, the SAP Cloud Platform acts as a central “data hub” in the system network. Multi-Cloud: Finally, there is also the possibility of bundling solutions and offers from various cloud providers under a common roof. This is called a multi-cloud, where, for example, the network infrastructure and applications can come from different providers. SAP has entered into strategic partnerships with cloud providers such as Amazon Web Services (AWS),Google Cloud Platform (GCP) and Microsoft Azure. Data Security for On-Premise and Cloud: When deciding on a cloud solution, data security aspects are also relevant for many companies. Initially, the on-premise solution appears to be the safer option compared to the cloud solution. However, on closer inspection, it must be noted that even an on-premise solution is not protected against cybercrime activities. Especially smaller companies often lack the know-how to protect themselves effectively against hacker attacks. On the other hand, cloud solutions today must meet the highest industry standards. These include security aspects such as external audits, data protection and data security, user management and “best practices” for data centre operations. Using SAP S/4HANA Cloud is certainly the most innovative way to break with traditional approaches. At the same time, it opens fascinating opportunities to rethink ERP software. One example is the possibility of the “Customer Influence Ticket”: customers can use it to request new functionality, and other customers can vote on whether they also consider this functionality to be useful and want to see it developed. If an idea receives sufficient support, it is put on SAP’s development roadmap. We strongly recommend taking a closer look at S/4HANA Cloud, Essentials Edition, when deciding which S/4HANA Version is right for you. Maybe it is only suitable for a part of your business processes or your organisation, but in these areas, you can benefit significantly from the enormous advantages of this new type of ERP software. Rise with SAP Initiative: In early 2021, SAP announced the “Rise with SAP” initiative which bundles a number of products and services in one package. The goal is to simplify the portfolio for customers, as well as giving an incentive to move to S/4HANA and consume SAP’s cloud service offerings like Asset Intelligence, Ariba, BTP, etc. 2.5 The Road to SAP S/4HANA 53 Rise with SAP contains the following: • Either SAP S/4HANA Cloud or SAP S/4HANA PCE • Tools and Services like S/4HANA Readiness Check and Custom Code Analyser • A small annual credit for SAP’s Business Technology Platform • SAP Business Process Intelligence Discovery Reports to benchmark customer processes • SAP Business Network “Starter Pack” which contains access to the Ariba Net- work, Asset Intelligence Network and Logistics Business Network 2.5.4 What Is the Right Approach for Moving to SAP S/4HANA: Greenfield Versus Brownfield Versus Selective Data Transition There are three ways to introduce S/4HANA (see Fig. 2.6). A greenfield installation is a new installation of an SAP S/4HANA system. The system is unconfigured and does not contain any data—customising, enhancements, data load, etc. will follow. In a brownfield installation, however, a new system is set up based on an existing SAP system. During a migration project, customising, data, authorisations, etc. are transferred from the source system. This is called system conversion. In a Selective Data Transition Project, data, customising and enhancements from one or more source systems are selectively migrated to the S/4HANA target system. There are some points to consider before making the decision for Greenfield or Brownfield: System Conversion (Brownfield) New Implementa�on (Greenfield) Selec�ve Data Transi�on (Landscape Transforma�on) SAP ERP System S4 On Premise SAP PaaS Cloud (HEC) SAP ERP or 3rd party System S4 On Premise SAP PaaS Cloud (HEC) S/4HANA Cloud SAP ERP Region A SAP ERP Region B SAP ERP Region C S4 On Premise SAP PaaS Cloud (HEC) S/4HANA S/4HANA S/4HANA Fig. 2.6 The road to SAP S/4HANA 54 2 What Makes an SAP Project So Different? • Are your current business processes appropriate for your long-term business goals? • If “yes”, you may want to go for a conversion, since the existing process configurations are largely adopted. • Can you significantly improve your business processes by adopting SAP best practices or the SAP model company? • If “yes”, this suggests a Greenfield approach, which offers the possibility to reconfigure and redesign business processes. • Do you want to consolidate your system landscape(s) at the same time during the S/4HANA implementation? • If “yes”, this suggests a Greenfield approach or a selective data transition, because you can consolidate source data from multiple systems into a new S/4HANA system. • Do you want to transfer existing transactional data to the S/4HANA target system? This is possible with Brownfield as well as with Greenfield but more complex with the Greenfield approach. There is no one-size fits-all SAP S/4HANA. The decision for a Greenfield or Brownfield approach, or even selective data transition, has to be made based on the respective circumstances. Greenfield Approach “Greenfield” means a new implementation of the SAP system(s). The business processes are remodelled, and the data from the legacy systems is transferred as if the source was a legacy (i.e. non-SAP) system. The existing production system can continue to operate in parallel while this strategy is implemented. However, do not underestimate the efforts for customising, developing enhancements and data migration. Many customers who choose the Greenfield approach also opt for the SAP “Model Company” to cut down on customising time. For more information on the Model Company, see Sect. 3.7.3. For SAP customers, who are migrating from a previous SAP version to S/4HANA, this method makes sense if it is possible to largely adapt the business processes to be newly modelled to the specified standard of S/4HANA and cut out the dead wood. In many companies that have been using SAP for years, time and again the standard SAP processes have been adapted individually to new business requirements. Takeovers and strong growth in many internationally active companies have also contributed to a heterogeneous IT system architecture and complex business processes. Many companies run several SAP systems side by side, which could possibly be consolidated to save maintenance and other costs. A very detailed examination of the business processes and the system architecture “end to end”, including the processes in non-SAP systems, is mandatory to get the necessary information for a sound decision. It is recommended to involve SAP or experienced external partners directly for this task. First, process experts create an 2.5 The Road to SAP S/4HANA 55 overall picture of the currently implemented processes before going into the process details: • Which processes are used? • Which extensions of process logic and data structures have been implemented? This information is compared with the SAP standard process and data model to get a picture of the expected effort. Master and Transaction Data If the Greenfield strategy is applied, the master and transaction data from the legacy systems can be transferred to the new S/4HANA system using data migration tools (e.g. SAP S/4HANA Migration Cockpit). It is important to transfer updated and cleansed standardised datasets to avoid data issues down the road; data quality has top priority here! Just as this principle applies to the initial transfer of data from a non-SAP system to an SAP ERP system, the same applies to the transfer of data from SAP to SAP systems. Unfortunately, data migration is the one area where many projects spend too little time and resources to ensure the quality is good—and the company pays a high price later. What happens with customising? Ideally, SAP’s collection of best practices or the SAP Model Company can be used for support. In this case, a large part of the customising is already preset. It should be noted here that the use of the Model Company means additional costs. Whether you then decide on a big bang (i.e. a simultaneous go-live of all SAP landscapes) or a multistage implementation depends mainly on the complexity of the migration and the associated risk assessment. We generally adviseagainst a big bang approach unless there is no way around it. With the Greenfield approach, it is possible to free oneself from legacy problems and at the same time take advantage of the additional new functionality. During the migration to S/4HANA, the existing SAP system will continue to run. This reduces the project risk for the new implementation. However, speed is of the essence for the new implementation project because the source systems will continue to change during the implementation project as the business develops. These changes must be captured and considered during the implementation of the new S/4HANA system. The standardisation of the systems reduces the costs for maintenance and updates. Overall, however, the project effort, such as testing the new processes during a new implementation and migrating the data, is higher than for a system conversion (Brownfield). In addition, the increased effort and costs for operating the existing SAP system landscapes and the new Greenfield landscapes should not be underestimated. Especially medium-sized companies with limited IT resources quickly reach their limits here. Brownfield Approach (System Conversion) In the context of a Brownfield implementation, the existing SAP system(s) serve (s) as the source for a technical migration (called S/4HANA conversion). This 56 2 What Makes an SAP Project So Different? involves a simultaneous upgrade (to the new S/4HANA release) and change (con- version) of the data structures. Some technical requirements have to be met: • The source system should already be a Unicode system. If this is not the case, a Unicode conversion must first be performed. Non-Unicode systems are rare; therefore, this is not an issue in most cases. • Dual-stack systems (ABAP + Java) are not supported. If the source system is a dual-stack system, a dual-stack split must be performed first. • The ERP system must be at least ECC 6.0. • OS and DB booths must also meet the minimum requirements before the conver- sion can start. SAP has created notes with detailed information. The Readiness Check The freely available SAP Readiness Check for SAP S/4HANA (https://help.sap. com/viewer/p/SAP_READINESS_CHECK) consists of several tools that examine the source system and provide information about the expected conversion efforts and activities. It includes an interactive dashboard that displays the results: • Consistency Check results • Categorisation of the results into mandatory and optional • Indication which tasks must be done before the project starts and which can be implemented during the project • System sizing recommendations and additional information for sizing calculation • Information about add-on compatibility and third-party add-ons • Information about BW extractors and unsupported (black-listed) IDoc interfaces Maintenance Planner As part of the Readiness Check for SAP S/4HANA, SAP offers the Maintenance Planner, a tool that checks the source system for activated business functions, industry solutions and add-ons. If a conversion is not possible, the Maintenance Planner indicates this. Incompatibilities occur mainly with third-party add-ons—in this case, the manufacturer must provide a new version, or the add-on must be removed. Simplification Item Catalogue and Simplification Item Check With S/4HANA, SAP has introduced a variety of simplifications in data structures and processes. Simply put, these are major changes in the code that lead to incompatibilities with previous versions. An extensive, version-specific list of the affected objects can be found in the Simplification Item Catalog at https://launchpad. support.sap.com/#sic 2.5 The Road to SAP S/4HANA 57 https://help.sap.com/viewer/p/SAP_READINESS_CHECK https://help.sap.com/viewer/p/SAP_READINESS_CHECK https://launchpad.support.sap.com/#sic https://launchpad.support.sap.com/#sic The Simplification Item Catalog contains not only descriptions of the objects but also information about the necessary activities in the respective project phases to implement these simplifications. As of 2019, the SAP Readiness Check contains the simplification check, meaning you see the list of items which need simplification (i.e. manual adjustments) when you run the SAP Readiness Check. To avoid searching through these objects by hand, there is the report Simplifica- tion Item Check for SAP S/4HANA, which should be executed as early as possible in the migration project (or even before the project start). The result of the report provides information about the effort required for the needed adjustments. Custom Code Analysis The custom code analysis examines whether there are customer developments that are not compatible with S/4HANA. With the help of the UPL (Usage Procedure Logging) and the ABAP Call Monitor, it can be determined whether this custom code is actively being used or is just lying dormant in the system. If it is in use by business processes, it must be updated, or it won’t work in S/4HANA. Incompatibilities mainly affect Native SQL statements in the customer ABAP code (which should not exist in the first place) and pool/cluster tables in customer namespace—these no longer exist in SAP S/4HANA. (Standard) pool/cluster tables created by SAP are automatically converted into transparent tables during the conversion. Experience has shown that about 30% of incompatible custom code is not used, i.e. this code can be deleted during the conversion project. 60% of the incompatibilities can be fixed by largely automated “quick fixes”, and about 10% must be adjusted manually. With the Brownfield strategy, existing processes (unless they had to be adapted for compatibility reasons) are transferred to the S/4HANA system as is. This is particularly advantageous if the processes largely meet current requirements. The project duration is therefore usually shorter compared to a new implementation. However, it can be assumed that the full potential of the S/4HANA functionality cannot be exploited with this approach and that the system complexity is not significantly reduced. On the other hand, change management activities, such as training, can be estimated to be lower compared to the Greenfield approach. Existing in-house developments that are important for the business processes can be taken over. Since the existing legacy data is also migrated automatically, proactive cleans- ing and updating of the data is not only recommended but absolutely necessary. As always, the rule is “garbage in—garbage out”. Success Factors for a System Conversion From a project management perspective, the following success factors, recommendations and planning approaches must be considered for a system conversion: 58 2 What Makes an SAP Project So Different? • Simplification • Finance • Test runs • User experience (UX) The migration to S/4HANA offers the possibility to replace customer-specific application code with SAP standard processes and to simplify existing processes. Detailed simplification lists are created for the topics in question and are updated on an ongoing basis. Every project member and the key users must be familiar with the simplification lists. Sufficient time should be provided in the project plan for workshops, training and change management activities. To successfully implement a system conversion to S/4HANA, process expertise, application management and very good financial skills are required. Practice has shown that projects without the use of financial experts regularly struggle. Therefore, financial expertise is a “must” in a project! The technical requirements or the technical expertise of the SAP experts involved should also not be underestimated. As always, the shorter the productive downtime, the higher the effort and expertise required from the technical team to make it happen. The test runs run on a sandbox with a current copy of the production system. Two to three test runs should be the minimum. However, if necessary, more can be scheduled. To build upskills, the testers are integrated into the project at an early stage. It is advisable to keep a detailed runbook in which the sequence of activities, the errors and their correction and the time required for this are documented. This requires a certain amount of discipline, but it pays off! Recommendations • Clarify whether you can archive data to reduce the volume of data to be migrated. During the migration runs, the system checks whether the data in the tables is consistent. Especially in the financial sector, inconsistent table entries lead to problems that can stop and delay migration activities. • Third-party applications and add-ons must be checked and tested at an early stage to determine whether adjustments are necessary. In some cases, the third-party software may no longer be supported in the S/4HANA environment. • It also makes sense for dedicated process experts to work closely with the business functions and business teams in the project. • Although in many cases SAP GUI can still be used, you should plan to use the new SAP Fiori user interface in order not to miss any innovations and to be able to integrate mobile devices, such as smartphones and tablets. • Finally, be sure to run basic housekeeping jobs to reduce the amount of unneces- sary data prior to conversion. In the S/4HANA environment, some logistics processes will in the future be handled in the finance module. There are also completely new processes that were not available in the old SAP ERP solution. This requires an early review of the 2.5 The Road to SAP S/4HANA 59 authorisation concept and user access. It makes sense to deal with possible problems in the financial area and with customer and supplier master data before the project is started. The creation of a realistic project plan will only be possible after the S/4HANA Readiness Check is executed, mandatory items are fixed, and the first migration test run. This first run will, as already mentioned, be performed on a sandbox that represents a current copy of the production system (see Fig. 2.7). You will only know at this point in the project how many and which problems in terms of content must be solved before or during the actual migration. SAP expertise should be consulted to optimise the downtime of the production system. The fact that the first attempt may cause longer downtime than planned is not a great cause for concern. This is to be expected, and this is also the reason why the project plan provides for at least two, three or even more test migrations. Planning for a System Conversion Figure 2.7 shows the specific migration steps for the changeover from the existing ERP system to SAP S/4HANA. In the first phase of the migration, configuration adjustments are made, before it is possible to carry out the technical part of the migration. Further adjustments are necessary after the migration is complete. Plan sufficient time for testing and correcting the business processes in the unit test. It is even possible that adjustments need to be made in the old ERP system. For example, if you make changes to customer master data or even supplier master data, take time to carefully evaluate the existing processes to prevent possible problems during the migration. Data correction during migration is an iterative process that must be carried out until you have a good understanding of the issues and how to solve them. Plan a sufficient time buffer for corrections during the S/4HANA migration in order not to jeopardise the go-live date. We recommend to tackle the different options early in the project and to develop a roadmap that best fits your situation. The successful transition to the new S/4HANA platform will ultimately help you to reap the benefits of all the innovations.

If neither the Greenfield nor the Brownfield approach is suitable, SAP and a number of third-party companies support customers in their individual changeover to SAP S/4HANA. To this end, SAP has formed a new working group with four consulting firms (CBS, Datavard, Natuvion and SNP) called SAP S/4HANA Selec- tive Data Transition Engagement, which is intended to facilitate the migration of major SAP ERP customers to SAP S/4HANA. These partners are developing solutions that combine the characteristics of a classic new implementation with those of a system conversion. In the process, master data and balances are transferred to the SAP S/4HANA environment on the migration date. This also applies to certain business objects with their complete or partial history. In addition, it is defined which changes to company structure and business processes make sense during data migration (so-called valid migration scenarios). Here, the group follows a selective approach that can be combined with the SAP Model Company. This means that customers can continue to choose freely from the products and services of the various providers. The working group will not develop common new software for hybrid data migration. (https://support.sap.com/en/offerings-programs/support-services/data-manage ment-landscape-transformation/selective-data-transition-engagement.html) This is begging the question: why isn’t everyone taking the Selective Data Transition approach if it offers the best of both worlds? The answer is mostly “the price tag”. These projects are significantly more expensive and more complex than Brownfield or Greenfield approaches. Conclusion: The advantages of the Greenfield approach include a complete overhaul of pro- cesses, correct data sets and the chance to get rid of obsolete legacy processes. Leveraging the Model Company approach, you can avoid “starting from scratch” when it comes to customising and developing enhancements, but it involves extra cost and is not available for all industries and solutions yet. The Brownfield approach makes it possible to bring your existing SAP ERP system to SAP S/4HANA. This approach makes sense if the ERP system is relatively close to the SAP standard. It can generally be assumed that the conversion is less time-consuming than a new implementation with the Greenfield approach. Selective Data Transition will be the exception but offers interesting possibilities to consoli- date system landscapes. However, as these system conversions via Selective Data Transition are complex and expensive, this procedure is more likely to pay off for companies with a large number of SAP system landscapes and an equally large potential for consolidation. 2.5 The Road to SAP S/4HANA 61 https://support.sap.com/en/offerings-programs/support-services/data-management-landscape-transformation/selective-data-transition-engagement.html https://support.sap.com/en/offerings-programs/support-services/data-management-landscape-transformation/selective-data-transition-engagement.html 2.5.5 Data Migration Aspects of the Greenfield-Approach Data Always Causes Problems in the Greenfield Approach, but It is not Possible to Do Without Data can be a nightmare! It doesn’t help to duck away or ignore it: problems with data or data quality keep catching up with you throughout the entire project. Data migration is a topic that often does not receive the necessary focus in the initial phase of a project. In a Greenfield, as well as a classic SAP project, data must be migrated either from the legacy systems to a structured SAP target system or, as in our case, from an existing SAP ERP system to the new SAP S/4HANA system. This is an elaborate and complex process, starting with the analysis of the data, the setup of the test systems and finally the migrationof the master and transaction data into the new SAP system within a quite limited time. The data migration strategy is therefore an elementary component of the project and, as mentioned above, builds on the procedures to be replaced. The migration objects that are a prerequisite for the SAP S/4HANA implementation are predefined, which makes it a little easier. The following questions must be clarified: • Which activities must be used for the data transfer, and what are the responsibilities, roles and schedules? • Which data must be transferred, edited or deleted for each migration object? Identify Data Sources To find out which data you have to migrate, you have to look at the data in the source systems (e.g. open invoices from the previous year, open orders, master data such as customers, materials, products and suppliers). The results of the analysis of the data sources are data profiles with information on the content, structure and quality of the data sources. Another important step is to determine the business-relevant data that can be cleaned, harmonised or even deleted. It is useful to develop a standardised procedure for data migration and data cleansing activities. Can the following questions be answered in advance? • In what order must the data be transferred? • What are the quality requirements for transferring the data into the SAP S/4HANA system? Statistical Evaluations A mock data migration is performed to check the quality of the migrated data. The data migration test consists of several cycles with the following statistical evaluations: • Is the transferred data complete and how much data is transferred? • Is the transferred data correct in terms of content? 62 2 What Makes an SAP Project So Different? • How long is the data transfer time? • What is the error rate? Error Rate The number of migration cycles is therefore repeated until a qualitatively satisfactory data quality is achieved (e.g. error rate < 1%). After each cycle, further data cleansing activities need to be carried out. It is impossible to overstate the importance of this! A high data quality is the prerequisite for a successful test and the final transfer of the data into the S/4HANA system, and without doubt, data cleansing in the project is a labour-intensive process that must be planned accordingly! What Tools Are Available for Data Migration Activities? SAP Data Migration Cockpit: A Good Choice! With the SAP Data Migration Cockpit, which is the successor of the Legacy System Migration Workbench (LSMW), SAP provides a convenient and powerful tool to support the migration activities of master and transaction data from non-SAP and SAP systems to S/4HANA. The following activities are supported: • Overview of tables and objects for migration • Execution of the data migration • Maintaining the correct sequence of all migration activities • Overview of all completed migration runs • Error handling • Repetition and suspension of migration activities First, a list of all pending migration activities is drawn up. This list contains the number of tables to be transferred with the number of table entries. The individual activities are then processed sequentially. Errors are displayed and possible solutions are suggested. A correction is not necessary in every case. For example, if old table entries in the SAP ERP system are no longer needed in the new S/4HANA system, the errors can also be ignored. For master data management, SAP offers the newer SAP Master Data Governance application. For further details on the topics, see Sect. 9.4.3, “Master Data Management” and Sect. 9.6, “SAP S/4HANA Migration Cockpit”. Loading the Data When all data cleansing activities have been carefully completed and all further preparations have been made, the data can be loaded into the final production system SAP S/4HANA. Various tools are available to support this process, enabling the data to be loaded according to the data migration strategy. The sequence of the loading processes can be adjusted and adapted depending on the data volume to be loaded. 2.5 The Road to SAP S/4HANA 63 However, a certain sequence of the data to be loaded is mandatory, e.g. first the customer master data and then the corresponding orders (transactional data). After each data load, certain characteristics are checked again, e.g. whether the number of loaded data records has arrived correctly in the target system, the totals match, etc. Errors must be corrected immediately at this stage, either by manual intervention or by automated correction tools (programs). 2.5.6 Economic Feasibility Considerations/Business Case Value Discovery Workshop The commercial starting point for an S/4HANA project is of course the business case. SAP offers a Value Discovery Workshop for SAP S/4HANA. Consultants and architects from SAP and specialists (SMEs) and managers on the customer’s side discuss the problems with the existing ERP system. To allow comparison with the industry, a benchmark analysis of critical business processes can be carried out to define potential for improvement. The result is a cost-benefit analysis of the intro- duction of an SAP S/4HANA system. To be able to conduct such discussions efficiently, the customer needs to be well prepared with the following activities: Identify Problem Areas and Pain Points This is about identifying real business problems and setting priorities. In parallel, study the available information material about new functions und possibilities that can be implemented with SAP S/4HANA. Existing SAP ERP customers can also request the SAP S/4HANA Business Scenario Recommendation report via the self- service tool (see https://d.dam.sap.com/a/AREDtXr/Process_Discovery_How_To- V36.pdf). The SAP Transformation Navigator gives you a framework for your digital transfor- mation journey and—based on your answers—shows the way forward (see https:// go.support.sap.com/transformationnavigator/#/welcome). Both tools provide a good overview of the benefits that a migration from an existing SAP ERP system to an SAP S/4HANA system can bring (Fig. 2.8). Quantifying Problem Areas There are various approaches to quantifying the problem areas. You can either compare your company with competitors using publicly available information (e.g. annual financial statements) or with the help of a benchmarking tool such as the SAP Value Lifecycle Manager (see https://vlm.cfapps.eu10.hana.ondemand. com/index.html#/home). For example, you can calculate the productivity losses caused by inefficient processes in the manufacture of products or compare inventory costs with leading companies in the industry. 64 2 What Makes an SAP Project So Different? https://d.dam.sap.com/a/AREDtXr/Process_Discovery_How_To-V36.pdf https://d.dam.sap.com/a/AREDtXr/Process_Discovery_How_To-V36.pdf https://go.support.sap.com/transformationnavigator/#/welcome https://go.support.sap.com/transformationnavigator/#/welcome https://vlm.cfapps.eu10.hana.ondemand.com/index.html#/home https://vlm.cfapps.eu10.hana.ondemand.com/index.html#/home Identify Potential for Improvement Through the Use of an SAP S/4HANA System What are the benefits of switching to SAP S/4HANA? In this section, the financial impact and the benefits of using an SAP S/4HANA system is determined. In addition to the hard monetary factors, such as savings on the IT side by replacing a complex system landscape or a reduction in personnel cost on the IT and user side, also consider soft factors such as possible increases in sales through higher customer satisfaction with improved processes or better data quality available in real time for corporate management. Also do not forget to point out the risks for the project and the changeover. The assessments of customers who have already converted to SAP S/4HANA and have published their experiences are also helpful here. Compare Costs and Benefits When all the information is finally collected and available, the business case or a profitability calculation canbe prepared. Try to set up a realistic cost-benefit analysis, and proceed in a structured manner. If there are several proposed solutions to a problem, evaluate the individual alternatives. The business case created in this way can then be extended by further detailed analyses, for example, by subdividing and analysing problem processes into further sub-processes (https://news.sap.com/ 2017/11/how-to-write-your-first-sap-s-4hana-business-case/).

Data can be analysed in real time, leading to accurate and reliable business forecasts. The possibilities offered by the Intelligent Suite are impressive. Process simplifica- tion leads to more efficient audit management and thus to qualitatively better risk management. With the SAP Business Technology Platform, new business ideas can be implemented more quickly, resulting in a faster time to market. The infrastructure costs for the system can be reduced, among other things, due to the lower storage requirements. Despite all the qualitative and quantitative advantages that the use of an SAP S/4HANA platform can bring, it should not be underestimated that the road to S/4HANA must be planned very carefully, the necessary means and resources must be available and it requires an experienced project team with the support of qualified consultants to be successful. In our experience, the implementation costs for the new software are often underestimated for various reasons, and on the other hand, the savings are inflated to get the project off the ground. It is beneficial to inject a dose of realism at this point! These are the three most important KPI for the successful changeover to SAP S/4HANA. 1. SAP projects require top management support! SAP projects are transformation projects with effects on processes, system landscapes and organisational structures in your company. You as a project manager have to be a master of multitasking because competing resources must be coordinated across several projects. Transformation projects or multi- projects require company-wide and cross-organisational control. SAP projects are therefore usually decided on at top management level, and management must be involved throughout the project. The effort required for an SAP implementation and the changes and effects associated with it are often underestimated, and executive sponsorship is crucial to overcome the inevita- ble stumbling blocks and resistance in the organisation. 2. The adaption of business processes is an opportunity. Unlike the development of individual software, SAP projects start with standard business processes. This applies to a change from a legacy system to SAP as well as from an SAP ERP system to S/4HANA. The adaptation of business processes to SAP processes is a great opportunity for simplification. Changes and modifications to the standard are difficult and costly. Even if SAP processes may seem inflexible at first glance, simplification is the key to realise the potential for savings. Programming efforts are reduced by adapting existing business processes to standard SAP processes. However, do not (continued) 66 2 What Makes an SAP Project So Different? underestimate the requirements around change management to overcome concerns and fears within the organisation. 3. Spot on data migration: don’t forget to clean the house. Data migration is a costly and complex process. Data cleansing and archiv- ing tasks are an elementary part of any data migration strategy and must be considered in the project plans. The tasks must be carried out early and continuously in the project. Unfortunately, data migration is oftentimes treated like the proverbial unwanted stepchild. Squeezed for time between (delayed) customising finalisation and the need to start integration/user acceptance testing as part of go-live preparations, it does not get the attention, resources and time it needs to ensure the data quality is up to par. The business pays a high price after go-live, dealing with (and manually cleaning up) dirty data. 2.6 Conclusion 67 The SAP S/4HANA Project: How It Should Be 3 In an ideal world, our book would be finished after this chapter: here, you will get to know the best planning and implementation of an SAP project, in which project management, project staff and the entire team adhere to this planning perfectly. If only everything were that simple! Then, there wouldn’t be so many projects that are finished late or never completed at all. There would also be no projects whose scope changes over and over again in the course of the project, which in the end do not or only partially achieve their goals and have to be marketed as “great successes” even though in reality they weren’t. Nevertheless, many companies approach large IT projects that have the potential to change the entire corporate structure, business-critical procedures and processes (such as an SAP S/4HANA implementation) with remarkable naivety. The expenses for professional project management are all too often among the first budget items to be slashed. We like to compare project management with oil in an engine, even if a project management, on the surface, only produces costs: too little or no project management at all leads to serious damage in the project, up to total loss—project cancellation and write-off of costs. In contrast to lawyers, engineers or doctors, project managers are not protected professional titles with nationally or even internationally recognised training. Irrespective of the level of education, experience and qualifications, every project manager or even program manager can call themselves project manager. This leads to very diverse quality in project management. However, for some years now, formal qualifications—not only the general reference in the CV of years of experience (which can hardly really be verified)—have become more important when it comes to the selection of external consultants. This is a difficult situation for companies that have considerable financial resources at their disposal and whose economic future depends largely on a successful SAP project: how can you ensure that you hire a project manager who knows their trade? We have already referred to this in the introduction: the majority of IT projects fail partially or completely. Industry publications report regularly about large “SAP projects” (mostly managed by SAP partners) which struggled with long delays or # The Author(s), under exclusive license to Springer Nature Switzerland AG 2022 D.

And the affected companies paid dearly— losses up to US$ millions! Good project management is crucial for project success! Good project management is to a large extent a craft, i.e. the application of proven best practices and methodology. Projects are dynamic, complex entities of formaland informal processes, relationships and motivations. No one can fully understand and predict a complex project. Therefore, a proven methodology and best practices are crucial tools for success. Tip: Book Recommendation If you want to learn more about managing complex situations successfully, you should read Dietrich Doerner’s very informative and easy-to-read book The Logic of Failure: Recognizing and Avoiding Errors in Complex Situations, which was published as early as 1997. Take this chapter as a frame of reference to which we will refer again and again in the following chapters. The pitfalls and challenges, the predictable and unpredictable problems and surprising twists and turns that we present to you in the course of this book can thus be compared with the SAP S/4HANA implementation project as it should be. First of all, we show you how the journey begins and what prerequisites need to be created in order to then describe an SAP S/4HANA project with all its phases and structure. Imagine your boss giving you a free hand in planning and implementing your project. You can ask for anything (as long as it contributes to making the project a success), and nobody complains about budgets to be adhered to, tight schedules and lacking resources. 3.1 Project Management Standards, Methodology and Tools: An Overview President Harry S. Truman had a famous sign on his desk in the Oval Office: “The buck stops here”. In our case, this refers to the role of the project manager, either from your company or as an external service provider. Many companies commission consulting firms to carry out SAP projects and therefore decide on a dual leadership: an internal project manager who is responsible for the successful planning and implementation of the project together with an external project manager. In a broader sense, it is often even a “triumvirate” of internal and external project management and the solution architect, who is responsible for the entire content of the project. Whether you manage an SAP project exclusively with your own team or com- mission one or more consulting companies, in addition to the qualifications of the project members, the qualifications of the project management are particularly important. 70 3 The SAP S/4HANA Project: How It Should Be A number of international project management standards and related organisations have developed that are dedicated to standardising project manage- ment methodology and improving project management quality through training and certification. These project management standards now offer a whole slew of tools and methodological procedures that support you in the planning and implementation phases of the project. The organisations behind them ensure the continuous devel- opment and improvement of the methodology and tools. The “Big 3” of Project Management Standards Three major project management methods with associated organisations and inter- national certifications have become established worldwide. These trainings and certifications are designed to ensure project management quality standards: 1. The Project Management Institute (PMI), headquartered in Newtown Square, PA (incidentally, very close to SAP America’s corporate headquarters), has devel- oped a project management methodology which is described as best practices in Guide to the Project Management Body of Knowledge (PMBOK Guide). PMI is the project management organisation with the largest number of members world- wide. There are eight internationally recognised certifications, the most important and most widespread of which is the Project Management Professional (PMP) certification, which is valid for 3 years and requires continuous upskilling during its validity. 2. The PRINCE2 Project Management Methodology (Projects in Controlled Environments) was originally developed by the Office of Government Commerce (OGC) in Great Britain and is now part of AXELOS, a joint venture between the Cabinet Office of the British government and the Capita Group. In addition to PRINCE2, the well-known ITIL certification (IT Infrastructure Library) is also part of this. It is a collection of best practices for which training and standard certification is offered. ITIL has become a de facto industry standard in IT service management. 3. In Europe, the project management association IPMA (International Project Management Association) was founded, which also functions as a certification body for project management standards. IPMA published the ICB (IPMA Com- petence Baseline), which is the basis for national project management baselines. These national project management standards are based on the ICB and addition- ally consider country-specific requirements. The current version is ICB 4.0, which covers the three fields of competence (behavioural, contextual and techni- cal competencies). IPMA has local partner organisations in 72 countries. IPMA USA issues four types of certificates: – IPMA Level D: Certified Project Management Associate – IPMA Level C: Certified Project Manager – IPMA Level B: Certified Senior Project, Program or Portfolio Manager – IPMA Level A: Certified Project, Program or Portfolio Director 3.1 Project Management Standards, Methodology and Tools: An Overview 71 Tip: Professional Qualifications If you want to take on responsibility for an SAP project as a project manager in your company, you should be familiar with at least one of these standards and ideally have acquired the corresponding certification. 3.1.1 Selection of the External Project Management If you commission an external project manager with the responsible implementation of your SAP project, a proven project management certification is one of the must- have assignment criteria in addition to a reference list of successfully completed SAP projects. On the one hand, it increases the likelihood that good, qualified project management will be assigned—and thus improves the chances of success for your project. On the other hand, this approach contributes to the standardisation of the project management profession and thus to better quality for all SAP implementation projects. Now the time has come: several candidates are introduced and offer their services. What should you pay attention to? In the following, you will find some assistance for the selection of the suitable project manager for your SAP S/4HANA project: • Formal qualification This includes project management certifications but also relevant industry know- how. • References Contact the references provided, and try to find out detailed information about previous projects as well as strengths and weaknesses of the candidate. • Communication skills The project leader must be a good communicator and be able to motivate, convince and lead both the project team and the stakeholders. The most important project currency is trust—and the project leader must radiate this. • Language skills Nothing connects and separates us more than language. Business-fluent English is a matter of course; other languages like Spanish are an advantage, especially if it is an international project. As an aside, make sure that the standard project language is actually consistently followed in international teams to avoid misunderstandings and tensions between project members. • Gut feeling Trust your gut feeling! If, after getting to know each other and after an in-depth interview, you have the slightest doubt about the applicant’s suitability, you should continue your search. Guiding principle: never give anyone the benefit of the doubt! A technically well-qualified and personally convincing project management is a central success factor for your SAP project. Take your time in the selection process 72 3 The SAP S/4HANA Project: How It Should Be and do not hesitate to reject candidates proposed by an external partner if they are not completely convincing. Several interviews with different stakeholders can round-off the candidate selection process. 3.1.2 The Importanceof Project Management Methodology SAP projects, like all other major projects, are complex systems. They are characterised by their own dynamics, interconnectedness, polytely (i.e. pursuing several, sometimes even contradictory goals at once), intransparency and complex- ity. What does this mean? • Momentum The project continues to develop and move forward on its own—irrespective of the actions (or inactions) of individual actors. • Interdependencies “Everything depends on everything”. Changes in one area (sometimes surpris- ingly) lead to changes in other areas. • Polytely From Greek roots poly- and -tel-, meaning “pursuing many goals”: managing a project requires weighing up and balancing possibly conflicting objectives in order to achieve the overall objective (e.g. quality objectives vs. timetable). • Opacity and complexity It is not possible to have an overview of all aspects of the project at the same time. Everyone involved in the project sees only a part of it but often thinks he/she has understood the project. In fact, it is more like looking through a frosted glass pane: much is blurred in its details and can be guessed rather than clearly identified. Consistently Planning Ahead Enables Timely Countermeasures These are the basic reasons why many projects only achieve their objectives to a limited extent: complexity, momentum and lack of transparency inevitably lead to wrong decisions with sometimes far-reaching consequences. A good project man- agement methodology reduces the probability of poor decisions and—if they are recognised in time—gives you sufficient time and opportunities to minimise the fallout. Basic project management tasks, such as the preparation of a work break- down structure, a time schedule, risk management, etc., are activities that reduce complexity, make the interconnectedness visible and thus at least somewhat reduce the lack of transparency. They provide the project management with important structures and information for forward-looking planning and well-founded decisions. A generic project management methodology, i.e. not SAP-specific, is an impor- tant foundation for both Accelerated SAP (ASAP), the “classic” SAP implementa- tion methodology, and the successor SAP Activate. 3.1 Project Management Standards, Methodology and Tools: An Overview 73 There is no project management methodology prescribed by SAP. However, in practice, many SAP project managers are PMI or PRINCE2 certified, and as we will see, there are overlaps and similarities between PMI/PRINCE2 and ASAP. Before we go into ASAP and SAP Activate in more detail, we will give a brief overview of the PMI project management methodology: the PMI methodology is one of several possible structured approaches—it is a good tool, but certainly not the only tool in your project manager toolbox. The decisive factor is not which methodology you have chosen but its consistent and competent application in your SAP project. 3.2 The Project Management Basics: PMI Project Management Methodology Every project is different—and yet all projects have a lot in common. There are certain aspects that do not change, and therefore, there are good practices that are helpful in every project. Of course, there is a big difference between designing and building a motorway bridge, developing and launching a satellite into space or implementing SAP standard software. What Defines a Project? But there are still many similarities: for example, every project has a defined beginning, a defined scope and a defined end—and in between project phases with milestones that have to be passed or achieved. In contrast to day-to-day business, each project phase has specific tasks and deliverables, results that must be success- fully developed and “delivered” as well as milestones that must be reached in order to bring the project successfully to its goal. The project management methodology structures projects. It provides a frame- work and conveys concepts and technical terms that help every project manager to plan a project professionally and to manage it successfully. It is at least as important that the project management methodology conveys technical terms and concepts, a kind of project management language that facilitates the exchange between project managers. Just as every doctor knows what a fracture is, trained project managers know exactly what is meant by a work breakdown structure (WBS). Standardised Methodology Founded in 1969 in the USA, PMI has been editor of the PMBOK Guide. According to PMI, each project consists of the following phases, also called process groups (see Table 3.1). Phase 4 (monitoring and control) is a special case: unlike the other phases, this activity takes place throughout the entire project duration—so the jury is still out whether it is a separate phase or activities within all phases. 74 3 The SAP S/4HANA Project: How It Should Be Phases and Knowledge Areas: All at the Right Time! Let’s set the discussion about phase 4 aside as a minor issue: the PMI methodology consists—and this is key for understanding—of a matrix of temporal project phases and content-related topics, the knowledge areas (see Table 3.2). The PMI methodology of project management offers great support, as important tasks are listed for each project phase and each knowledge area. This is an important orientation in order to keep all necessary project management tasks in view in each Table 3.1 PMI process groups Phase/process group Details 1 Concept and initiation(conception and project preparation phase) Clarification and definition of the project objectives. Agreement/creation of a common understanding 2 Definition and planning(definition and planning phase) Planning of project content and scope; development of project, time and cost plans taking dependencies into account 3 Execution(execution phase) Assignment of project resources to activities in the project plan 4 Monitoring and controlling (monitoring and control) Reporting and change management 5 Closing(project completion) Order completion and administrative project completion Table 3.2 Knowledge areas according to PMI Knowledge area Details 1 Integration management Coordination and exchange of information between the project participants 2 Scope management Definition and monitoring of the project content; processes for initiating and rescheduling necessary changes 3 Time management Monitoring compliance with the timetable 4 Cost management With the help of project cost accounting, the cost trend is monitored, and necessary measures are taken 5 Quality management Standardisation of project processes and documentation of results 6 Human resource management Allocation of project resources to the project tasks according to training/qualification 7 Communication management Information exchange with all project participants 8 Risk management Risk analysis, preventive measures, mitigation and emergency concepts 9 Procurement management Cooperation with partners and suppliers 10 Stakeholder management Coordination and agreement with project participants inside and outside the project 3.2 The Project Management Basics: PMI Project Management Methodology 75 project phase. This is where the circle closes: structuring, reduction of complexity, focusing on the essentials, advance planning, and risk management—these are the tools of the project manager’s trade which increase the chances of successfully completing a project. As Mark Twain rightly said, “Forecasts are difficult, especially when they concern the future”. Therefore, even the best managed project can fail. Without a doubt, project success is the goal. But the task of project management is also to do everything possible to minimise the risk of failure and to maximise the available time for countermeasures through long-term planning. 3.3 Everything Perfectly Prepared: The Ideal Conditions The right course must be set long before the first phase of your SAP project begins. Dealingwith the requirements that ultimately set the SAP project in motion has already begun with the corporate strategy, which comes before the IT strategy and before the decision for SAP software. For our ideal project, we assume that the company has decided on an IT strategy based on SAP products. We have discussed the decision criteria in detail in Sect. 2.4.5, “Software Selection Criteria”. Consequently, the decision to implement an SAP S/4HANA implementation project does not come out of the blue: your processes or even your business model changes, parts of your company are sold, or other companies are bought. All these changes also require a change in your IT system. The basis for all plannable changes in the company should be long-term, strategic decisions, which are regularly reviewed and, if necessary, reassessed. Sustainable corporate management is characterised by long-term corporate strategies which include a suitable IT strategy. It may be clear from a distance that such a long-term view often runs counter to short-term profit maximisation, but nevertheless, these strategic decisions lay the foundation for a successful SAP project. Figure 3.1 shows an ideal project organisation embedded in the line organisation and supported by subject matter experts from the respective departments. The specifications and the acceptance of the results are carried out by the line organisation, while implementation is the responsibility of the project team, which is divided into several sub-projects. The key tasks of project control, solution design and integration design (interfaces) are set up across sub-projects. The technical infrastructure is provided by the corporate IT. Note: Back to Start: Strategy Changes Unless you are using accelerators like the model company or the project scope is very limited, complex SAP projects often last longer than 12 months. Certain strategic projects, which are also rolled out to different regions, countries and business units after design and implementation, may take several (continued) 76 3 The SAP S/4HANA Project: How It Should Be years. A change in strategic direction during the project can become a very serious issue and jeopardise the success of the project. However, since this book is not about successful business management but about successful SAP projects, we will not focus on the effects of short-term changes in strategy. All strategic decisions have been made and confirmed by the management. The SAP project can begin. In the following, we will take a look at the first steps until the start of the actual SAP project. The Project Office as Command Centre The project management office (PMO) is the central point of every SAP project— this is where all the threads come together. You have staffed your PMO with colleagues who are up to the challenge. The members of the project office are the first point of contact for many topics. You should understand the technical content of the SAP project and have organisational talent. Often topics are discussed here that are not yet ready for “public” communi- cation. You as project manager must have full confidence in your PMO. Many “small” enquiries and tasks that make an SAP project possible in the first place come up here: whether you lack a workstation or the team urgently needs a meeting room for a sub-project, the colleagues immediately take care of it and always find a solution. There are no problems with the office supply in your project because your PMO reorders in good time. The PMO is also responsible for operational project planning, i.e. the maintenance of planning documents.

However, the most important task of the PMO, in our view, is that its members are the first to notice “atmospheric disturbances” in the project. Long before the first official discussions about any kind of malfunction, risks to the project or even interpersonal problems are started or the problem escalates, the PMO has already recognised it. It is therefore the heart of the project in more ways than one. This is illustrated by Fig. 3.2: the PMO plays a central role in the organisational structure of the project. It primarily supports you as the project leader but also has at least one virtual connection to each sub-project; and through the central administrative processes (onboarding, procurement of materials and workstations, etc.), all those involved in the project know their colleagues from the PMO. You can read more about the structure and tasks of the PMO in Sect. 6.1, “Support Whenever You Need It: The Project Management Office”. The organisational and administrative preparations for the SAP project are now almost complete. Before you start your work, you must choose a methodology for your SAP project: SAP Activate. In the next part, we explain how SAP Activate has developed from the previous implementation methodology ASAP.

Fig. 3.2 PMO as project headquarters 78 3 The SAP S/4HANA Project: How It Should Be 3.4 ASAP: The Mother of All SAP Methods Everyone who has been involved in SAP projects over the last decades knows ASAP. ASAP means Accelerated SAP and describes as a method or model the introduction of SAP software as a project. The fact that the abbreviation asap is widely known as an acronym for as soon as possiblewas certainly one of the reasons for the choice of name. With ASAP, SAP, the developer of the software, has provided a method for its implementation. ASAP Development Discontinued: ASAP was developed as a method by SAP in 1998. The last and final software version is ASAP 8.0 from 2013. Since then, ASAP has not been developed further; nevertheless, the documentation is still available today at https://archive.sap.com/ documents/space/asap-methodology. ASAP has been replaced by the new SAP Activate methodology, which builds on and extends ASAP. Some central things did not change during the move from ASAP to SAP Activate—therefore, we will first give a short overview of ASAP before we take a closer look at SAP Activate. Figure 3.3 shows the phases of the ASAP roadmap and the different tasks that need to be performed during each phase. In contrast to the five project phases according to PMI, ASAP comprises six phases.

Top-Down and Bottom-Up Planning: Planning is of central importance in a project: it is the key to success. A combination of top-down and bottom-up planning with the active involvement of all key stakeholders leads to the best planning results. During the project planning for the individual phases, it is advisable to plan the coming phase in detail and all future phases more high level. The current plan milestones are the basis for further planning, but it should not be set in stone. This means that you need to maintain a certain flexibility for future milestones, which is of course tightly linked to your scope management/change management processes. The Critical Path Determines the Duration of the Project: Determining the critical path (see Fig. 3.4) is the simplest way to estimate the total duration of the project in planning terms. All activities that lie on the critical path together or one after the other result in the total duration of the project. If there are changes in any of the activities on the critical path, the subsequent activities will move. Activities that are not on the critical path do not affect the total duration, so a late completion would not be critical, as it does not impact the overall project timeline. Process Defini�on End–to–end Processes End- to -end Processes Ini�al Architecture Defini�on Integra�on Architecture Define Scenarios Implementa�on Test Approval Cri�cal Path Set up the ini�al system landscape Fig. 3.4 Critical path in the project 80 3 The SAP S/4HANA Project: How It Should Be The critical path in Fig. 3.4 is composed of the following activities: 1. End-to-end processes 2. Definition of the scenarios and initial setup of the system landscape 3. Realise (implementation) 4. Test 5. Acceptance The remaining activities (e.g. the initial architecture definition and the integration architecture) are not on the critical path and therefore have no impact on the runtime of the project. Once the critical path is identified, project management’s attention focuses on all activities that lie on it. Please note, however, that the critical path may change during the course of the project. Activities that were previously not on the critical path may become critical due to a change request or if their delay becomes too large. Therefore, it is important to not only focus on the activities on the critical path but additionally determine how much buffer the rest of the important project activities have before they in turn affect the critical path. Prudence and diligence in controlling and monitoring the progress of the project will protect you from such unpleasant surprises. Note: The scope statement is the most important document created during the project preparation phase. It describes the project tasks and scope. The follow- ing points should be included in the scope statement: • Project Rationale: Explanation of why the project is necessary • Business Objectives: Overview of project goals to be achieved from a business perspective • Project Results: List of project deliverables to be developed by the project team • Project Exclusions and Project Assumptions: Any issues or tasks not undertaken by the project team and the assumptions on which project planning is based (e.g. strong revenue growth requiring better IT support) • General Conditions: Description of the financial, temporal and content- related framework conditions in which the project operates The scope statement is a working document. Each change request in the course of the project is compared with the scope statement to decide whether the changed/ additional requirements can be accepted or not. If a change request is accepted, an adjustment of the scope statement is often required. 3.4 ASAP: The Mother of All SAP Methods 81 3.4.2 Phase 2: Business Blueprint With phase 2 (business blueprint), the actual technical part of the SAP project begins. In this phase, it is necessary to describe the framework, the contents, the interaction with other systems, projects, departments and the technical implementation. Business Process Requirements: The most important and challenging, often most extensive and also most consequen- tial aspect, is the development and documentation of the business process requirements. They form (as shown in Fig. 3.5) the basis for process modelling and the subsequent mapping of business processes in the SAP system. The com- plexity should not be underestimated. The interaction between customising (master data and transaction data), additional developments that may become necessary and interface data must be described in detail at the process step level. The following topics are considered in the context of the preparation of the business blueprint: • Integration scenarios (interfaces) • Frontends (user interfaces) • Implementation sequence (central instance vs. distributed systems vs. rollout of a template) • Industry solutions, add-ons, third-party products • Go-live strategy For You Know What You Are Doing! The result of the blueprint phase is a largely complete overview of the process landscape and the associated architecture that will be implemented. This involves a Event Process step 1 Process step 2 Decision Process step 3 Result New Order Create Sales Order Check Inventory Iden�fy Suppliers Request Quotes Select Offer Create Order Delivery Received General Process Flow Example: Procurement Process Confirm Order Fig. 3.5 Example of a business process flow 82 3 The SAP S/4HANA Project: How It Should Be detailed assessment, as general statements have already been made in the prelimi- nary phases of the project. The goal of the blueprint phase is thus to create an implementable business blueprint. Documentation of the Blueprint—Knowledge Transfer: The results of the business blueprint are often compiled and filed in the form of documentation. In principle, the result of the business blueprint is the “book” of the project (sometimes casually called a “very expensive book”): • Blueprint document The blueprint document contains a description of the process landscape and the business concept. • RICEF or WRICEF planning document RICEF stands for Reports, Interfaces, Conversions, Enhancements, Forms and the W for Workflows. This document contains a description of all development objects. The objects to be developed are later documented in business and technical specification templates. • RACI matrix RACI stands for Responsible, Accountable, Consulted, Informed. This matrix is basically a table showing who does what in the project and is responsible for what (see Sect. 6.3.1, “Guidelines for a Successful Project Control”). Blueprint, WRICEF and RACI matrix are very important project documents that need to be carefully developed, versioned, approved and filed. They form the basis for the following realisation phase, so “version confusion” must be avoided at all costs. Additionally, make sure that every project member has access to this crucial information and knows how to find it. 3.4.3 Phase 3: Realisation After the acceptance of the blueprintphase, the implementation of the third ASAP phase follows immediately—the realisation phase. Now it is a matter of defining and implementing the processes documented in the blueprint phase and the underlying architecture in detail. This is usually the most expensive and time-consuming project phase. The main tasks in the realisation phase: • Building and operating the project systems • Customising and developments • Definition and selection of the business data • Interfaces and integration scenarios • Extensions • Users and authorisations • Archiving 3.4 ASAP: The Mother of All SAP Methods 83 • Non-functional requirements • Trainings • Test procedures 3.4.4 Phase 4: Production Preparation Almost Done! Tasks in the Production Preparation: Within the framework of phase 4, the production preparation (final preparation), the following tasks are performed: • End-user training • Setting up the productive system landscape • Preparing the productive data transfer • Cut-over planning This critical phase requires very careful planning and execution. For complex projects, so-called dry runs are performed to find possible mistakes and to practice the execution of the activities in the interaction of all parties involved. The less time is available for the actual cut-over, the more effort has to be put into the production preparation phase. Optimised technical procedures, such as minimised downtime service, reduce technical downtime during the go-live as well as organisational measures to speed up the handover between persons and teams involved. This is an optimisation task in which the most time-consuming tasks on the critical path are analysed and accelerated in several iterations until the goal, completion within the maximum available downtime, is reached. The most important milestone is completed when all tasks have been planned, documented and successfully tested. At this point, everything is well prepared for the culmination of the SAP project: the go-live. 3.4.5 Phase 5: Go-Live and Support The go-live and support phase shows whether the preparations were in fact good enough—although unforeseen surprises can still jeopardise success. The tasks in the go-live and support phase include the following: • Shutting down legacy systems • Execution, review and acceptance of the data migration • Final test of the productive system landscape with the loaded data • Obtaining the formal approval (go/no-go decision) • Activation of the interfaces • Opening the production system to the end users 84 3 The SAP S/4HANA Project: How It Should Be Once the Interfaces Are Activated, There Is No Way Back! The most important milestone in this phase is the go/no-go decision, which must take place before the interfaces are activated. Once they are opened and data is exchanged between the new production system and connected internal and external systems, there is usually no way back. If, at this point, the new production system has such serious problems that it is necessary to shut down and reactivate the previous systems, this will cause massive problems. In complex system landscapes, it is almost impossible to analyse the data exchange that has taken place up to that point via the interfaces and to post it in the previous system landscape. It would be a mammoth task under massive time pressure: the old productive system or the old system landscape can only be reactivated once the clean-up work has been completed, meanwhile business activities have to be suspended for the most part. In short, as long as the interfaces have not been reactivated, the go-live can still be aborted; after that, one can only try to rectify any problems that arise during operation as you go. The risk of serious problems during or after the go-live is considerable. Unfortu- nately, it often happens that details have been overlooked and now lead to difficulties as operations begin. Therefore, the go-live is followed by a so-called hypercare phase, where special measures and preparations are in place to stabilise the system and to solve problems in a timely manner. The new system is unfamiliar and poses new challenges for users, so supporting them is as important as solving technical problems. 3.4.6 Advantages and Disadvantages of ASAP ASAP is a proven implementation methodology for SAP ERP projects. In the 1990s and early 2000s, when many companies switched from legacy systems to SAP, ASAP was an important tool for making these projects a success and has proven its usefulness. Better Is the Enemy of Good! Companies that are about to implement their first SAP system today can continue to benefit from ASAP, but let us state it very clearly: SAP Activate is better! For most customers who have already passed the phase of initial implementation, the value of ASAP is limited. Its focus on classic SAP implementation is both a strength and a weakness: • Optimisation projects, which often start shortly after a large SAP implementation, include smaller, incremental improvements and go-lives; agile project manage- ment methods, consisting of sprints, are not well-supported by ASAP. • ASAP offers little assistance for introducing cloud-based solutions or building hybrid landscapes. 3.4 ASAP: The Mother of All SAP Methods 85 • ASAP focuses on software products developed by SAP—third-party software (especially in the cloud) is not in focus. In our opinion, SAP’s decision to release ASAP 8.0 as the last ASAP version and to rely on the successor SAP Activate instead was the right one. 3.5 SAP Launch: The Implementation Methodology for SAP Cloud Products While ASAP has traditionally been used for on-premise-based SAP implementations and has proven its worth, there is—and not every SAP expert knows this—another implementation method, especially for SAP cloud products, such as SAP SuccessFactors and SAP Ariba. SAP Launch consists of four phases, which will be briefly presented below: 1. Prepare (preparation) 2. Realise (implementation) 3. Verify (test phase) 4. Launch (startup phase) Prepare Phase The prepare phase corresponds roughly to the project preparation phase and the business blueprint in ASAP: first of all, it is about the development of a scope statement, the different roles and tasks in the project and the high-level project period (milestone plan). The second step is the solution design, i.e. the detailed description of the software solution. It is precisely in this phase that particularly close cooperation with the specialist departments is necessary to fully identify and incorporate the business requirements. The challenge lies in translating the business requirements into software features and capabilities. It is important to keep in mind what the cloud solution is designed for to create a viable solution design. In addition, integration issues are also highlighted: this involves connections between the cloud solution and other (on-premise) systems. Fundamental decisions, such as the use of middleware software or, alternatively, point-to-point interfaces, play an important role here. In addition, it is necessary to identify the data objects to be migrated into the cloud solution. At the end of this phase, the following important milestones have been reached: • All project participants have a common understanding of the project scope. What is and what is not covered by the project? • The scope also includes an approval procedure for scope changes in the project. How are scope changes evaluated in terms of effort and impact on the project 86 3 The SAP S/4HANA Project: How It Should Be duration? Who has the ultimate authority to decide whether a scope change is accepted? • Roles and tasks are defined. Certain tasks are carried out by experts; others— especially process test activities—are taken care of by employees of the specialist departments. • The solution design is at a very advanced stage. It describes in detail the functions of the software. It also includes the integration requirements, i.e. a plan forcreating or adapting the connections to other systems. Finally, the solution design includes a list of the data objects to be migrated. Realisation Phase In the realisation phase, the solution design is implemented in the development environment. The system configuration is carried out, and any development activities or adjustments are realised. It is important in this phase to involve the departments that will use the system in the future at an early stage. The phase is concluded with a discussion (walk-through) of the entire functionality with the department managers and their (hopefully) positive feedback on the implemented solution. Verify Phase Once configuration and development is complete, the solution is transferred to the test environment, and the verify phase begins. In a series of test runs, individual functionalities are first tested, followed by entire processes from start to finish. In addition, integration scenarios (if possible) are verified, and a test (mock) data migration is carried out. It is strongly recommended that the tests are carried out on migrated real data (pseudonymised if necessary) to obtain meaningful results. Launch Phase The launch phase is about the preparation and execution of the cut-over in the productive environment (the actual transition to the new system). The configurations and development objects are imported into the productive system, and the data transfer is carried out. After successful go-live, the system is handed over to the operations team, whose task is to ensure smooth operation from then on. 3.6 SAP Activate: The Better ASAP SAP Activate: The “Swiss Army Knife”: Over the years, the implementation of SAP software has become increasingly complex, which is not only due to the increased functional scope and complexity of the software itself. On the one hand, the SAP product range or range of solutions has constantly expanded, while on the other hand, the starting points or objectives of SAP projects vary considerably: some customers are planning the initial introduction of SAP software, others are about to switch to SAP S/4HANA, and yet others want 3.6 SAP Activate: The Better ASAP 87 to optimise their SAP system landscape through SAP cloud products. SAP Activate offers support for each of these different types of project. SAP S/4HANA Implementations SAP Activate supports all three current variants of SAP S/4HANA implementations, the focus of this book: SAP S/4HANA, on-premise version; SAP S/4HANA Cloud, Extended Edition (aka “Single Tenant Edition” or “STE” for short); and SAP S/4HANA Cloud, Essentials Edition. Functionally, these SAP S/4HANA variants do not differ in terms of technology stack—only the deployment option (on-premise version, private cloud, public cloud) varies, which in turn affects the implementation project. The possibility of making changes to the code is completely excluded for SAP S/4HANA Cloud, Essentials Edition, and quite restricted for SAP S/4HANA Cloud, Extended Edition. This affects the fit-to-standard analysis in the explore phase (see Sect. 3.6 “SAP Activate: The Better ASAP”). SAP Activate aims to take the different starting points between one customer and the next into account and offers the right tools and the appropriate methodology for the project. It is thus possible to introduce the SAP S/4HANA on-premise version as a “Greenfield version” as well as to carry out conversions to SAP S/4HANA (“Brown- field version”) and of course also the SAP S/4HANA Cloud variants. The general goal of SAP Activate is to enable customers to implement SAP solutions in a time- and cost-saving manner by providing them with additional tools in addition to the methodology: SAP Best Practices and Guided Configuration. SAP Activate is also integrated in SAP Solution Manager 7.2, and thanks to the SAP Model Company, a further time-saving is possible through ready-made customising. However, all this has led to a certain complexity of SAP Activate itself, as you will see below. The SAP Activate methodology, like ASAP, consists of six phases, as shown in Fig. 3.6. The monitoring and controlling tasks of project management, which according to PMI represent a separate phase parallel to the other project phases, Discover Prepare Explore Realize Deploy Run • Handover sales dept. to implemen- ta�on team • Scope defini�on • Compare business requirements and scope • Develop solu�on scenarios • Project Start: Define the business benefit and the success criteria • Define the basic con- figura�on • Set up and test the configura�on (based on requirements defined in the Explore phase) • Transfer the configura�on to the produc�ve environment • Support a�er go - live • Con�nuous maintenance and update of the systems to ensure stable opera�ons Fig. 3.6 The six SAP Activate phases 88 3 The SAP S/4HANA Project: How It Should Be are no longer represented as a separate phase in SAP Activate. Instead, these activities are integrated into the respective phases. We will first give you an overview of the phases and most important tasks in it. 3.6.1 Phase 1: Discover Before the actual project can start, it is necessary to create a company strategy for digital transformation or to revise and update it, if it already exists. It forms the overarching framework for the project. SAP S/4HANA as the future ERP system represents the core, but other important issues must also be considered: IoT, big data, omnichannel (i.e. integrated, coordinated customer communication across different communication channels to optimise the customer experience) and business networks (such as cloud solutions, SAP Ariba, SAP Fieldglass and SAP Concur) to name but a few. The question that needs to be answered is: which of these products promise significant benefits in the transformation of the company to an Intelligent Enterprise? The basic concept of linking O-data (operational data, business data) and X-data (experience data, customer experiences) must be applied to the company’s situation. At the same time, inject a dose of reality by always looking at operational aspects. The most sophisticated landscape has very limited value, if stable operations are not ensured. But back to the “daily grind” of project work: the next step is to analyse the functionality of SAP S/4HANA or the innovations compared to the classic SAP Business Suite. In addition to the functional changes and simplifications, the focus is also on SAP Fiori-based user experience and, for example, the possibility of realising agile innovations with the help of the SAP Cloud Platform. SAP offers free (time-limited or functionally limited) demo versions for many solutions, which can be used to become familiar with the innovations: SAP S/4HANA Trial Offers • SAP S/4HANA Cloud Trial (usable for 14 days), to be found at https://www.sap. com/cmp/oth/crm-s4hana/s4hana-cloud-erp-trial.html • SAP S/4HANA Trial (usable for 30 days), to be found at https://www.sap.com/ cmp/oth/crm-s4hana/s4hana-on-premise-trial.html • SAP Cloud Platform Trial (valid for 6 months, renewable), available at https:// www.sap.com/cmp/td/sap-cloud-platform-trial.html The Solution Scenario: Looking Back, Looking Forward The third step is the development of the scope or solution scenarios. In the case of an SAP S/4HANA conversion, it is recommended that in this early phase, the existing ERP system is analysed with the help of the SAP Readiness Check for SAP S/4HANA to identify necessary adjustments. This gives a first impression of how complex the conversion will be—and this is very important for further project planning. 3.6 SAP Activate: The Better ASAP 89 https://www.sap.com/cmp/oth/crm-s4hana/s4hana-cloud-erp-trial.html https://www.sap.com/cmp/oth/crm-s4hana/s4hana-cloud-erp-trial.html https://www.sap.com/cmp/oth/crm-s4hana/s4hana-on-premise-trial.html https://www.sap.com/cmp/oth/crm-s4hana/s4hana-on-premise-trial.html https://www.sap.com/cmp/td/sap-cloud-platform-trial.html https://www.sap.com/cmp/td/sap-cloud-platform-trial.htmlThe result is a business case as a basis for project approval. 3.6.2 Phase 2: Prepare The prepare phase marks the actual start of the project. The project team is assem- bled; scope and project plan are finalised: • Create project goals, high-level scope and project plan. • Name a project sponsor (executive level!), and win them over for the project. • Define project standards, project organisation and governance. • Define roles and responsibilities in the project team. • Analyse project goals in detail. • Set up project management structures, progress monitoring and reporting requirements. • Build up know-how in the project team: consultants get to know the client’s business; employees gain experience with the new SAP S/4HANA solution. • Carry out the project kick-off. 3.6.3 Phase 3: Explore Fit-to-Standard Analysis as a Main Task In the exploration phase, it is usually a good idea to hold joint workshops with customers, subject matter experts (SMEs) or key users and consultants in which the standard functionality is presented (preferably in a demo system!). In this fit-to- standard activity, it is possible to determine which gaps exist and which customising settings are necessary. This information must be carefully documented so that it is available as a basis for the development activities in the next phase. In addition, it is important content for the test cases to be created and executed in the next phases of the project. The most important activities in the exploration phase are as follows: • Fit-to-standard analysis • Definition of the configuration (customising) • Definition of user authorisations and system access • Preparation for data migration (Greenfield) • Test planning • Analysing the training needs of end users • Milestone: Phase completion and acceptance of the results The explore phase sets the stage for the implementation of the solution design. Thorough and detailed definition of the business processes—validated with the help of a demo system whenever possible—is crucial for a successful realisation phase. Any issues that have not been carefully planned and prepared will emerge in the realisation phase as open issues for which a concept and solution must be developed. 90 3 The SAP S/4HANA Project: How It Should Be In the worst case, these gaps in the solution design require further adjustments elsewhere, with potentially significant impacts on project effort and schedule. The more time and care is spent on the explore phase, the smoother the project progress in the subsequent phase. 3.6.4 Phase 4: Realise Agile Implementation of the Requirements: The most important tasks in the realisation phase are the configuration and testing of the solution landscape. SAP Activate supports agile methods, which means that the project team builds the solution in cycles/iterations (also called “sprints”): each cycle consists of a configuration, test and acceptance phase, together with the relevant documentation. At the same time, preparations for data migration (in the case of a Greenfield approach) take place. A key success factor in this approach is the close cooperation with experts from the specialist departments. They ensure that the solution actually meets the business requirements. Frequent and early deployment of the solution during agile develop- ment cycles is designed to shorten the project duration and improve the quality of the solution. These are the main activities in the realisation phase: • Setting up the system landscape (quality assurance and production system, usually called QAS and PRD for short) including the high availability landscape (HA system) • Configuration of the solution (customising) • Development of the solution extensions (development) • Structuring of the integration scenarios (interfaces) in the QAS landscape • Output management configuration (printer settings) • Planning and implementation of regular integration workshops (process walk- through) • Data transfer from the source systems: definition of the data objects and configu- ration of the data transfer tools • Preparation and execution of the tests: – Test cases – Test plan – Test execution and coordination – Correction of errors • Preparation of the training materials for the users • Preparation of the operating manual and handover plans • Creation of the cut-over plan • Milestone: phase completion and acceptance of the results 3.6 SAP Activate: The Better ASAP 91 Note: Continuous Quality Check and Improvement Services (free of charge). As part of the regular maintenance and support contract, SAP offers a range of Continuous Quality Check and Improvement Services. Some of them are free of charge (depending on the type of support contract) but must be ordered early (usually at least 6 weeks before the go-live). More information can be found at https://support.sap.com/en/offerings-programs/enterprise-support/ enterprise-support-academy/continuous-quality-check-improvement-services. html. 3.6.5 Phase 5: Deploy Production Preparation and Go-Live: In the deploy phase, the preparations and plans for the productive start of the new system landscape are finalised. This phase shows whether everything really fits together. Solutions must now be found for all remaining critical open points so that the go-live can take place. The systems are finally tested (e.g. by means of so-called final tests or user acceptance tests) to ensure that the sizing is sufficient for the expected data and user load. Note: System Sizing System sizing refers to the estimation of the system size (number of processors, size of the working memory, storage, etc.) so that the landscape can cope with the requirements, but on the other hand is not unnecessarily large. For many years, SAP has been offering the Quick Sizer tool at https://www. sap.com/about/benchmark/sizing.quick-sizer.html. There are three versions: • HANA • Classic • HANA Cloud The most important factors are the amount and expected growth of data (with the SAP HANA in-memory database, the amount of data should never occupy more than 50% of RAM), the number of users and the processes. Sizing is half science and half art, i.e. it is always an estimate. If sizing was carried out during the sales phase, experience shows that it is at the lower end and should be verified prior to go-live. The sizing estimate is never based on average system utilisation but on peak loads, which usually occur at the end of a month, quarter or year. 92 3 The SAP S/4HANA Project: How It Should Be https://support.sap.com/en/offerings-programs/enterprise-support/enterprise-support-academy/continuous-quality-check-improvement-services.html https://support.sap.com/en/offerings-programs/enterprise-support/enterprise-support-academy/continuous-quality-check-improvement-services.html https://support.sap.com/en/offerings-programs/enterprise-support/enterprise-support-academy/continuous-quality-check-improvement-services.html https://www.sap.com/about/benchmark/sizing.quick-sizer.html https://www.sap.com/about/benchmark/sizing.quick-sizer.html The exact design of the deploy phase depends on the chosen approach: a “big bang” approach is a go-live where all new functionalities are set live at the same time. With incremental go-lives, on the other hand, the functionalities are successively set live. The risk is lower than with the big bang, but you pay the price of the frequent adjustments to the system landscape that are necessary with each new functional go- live. In an (international) rollout project, one often proceeds country by country or region by region: one country or region after another is set live. These are the most important activities in the deploy phase: • Final configuration of the productive landscape – Import customising and custom developments. – Prepare interfaces and integration scenarios for the changeover. – Prepare data migration before the go-live (e.g. transfer of master data). • Finalisation of user training • Finalisation of the detailed cut-overplan, including contingency and emergency plans in case the go-live is not successful • Implementation of the cut-over • Go-live (go/no-go decision) • Milestone: Phase completion and acceptance of the results Note: Cut-Over Plan The cut-over plan contains a detailed list of all tasks, activities and responsibilities that arise during the go-live. Activities are usually planned down to hours and minutes in order to make the best use of the limited time available. It has proven useful to conduct a mock cut-over (dry run) before the actual go-live date, i.e. a dress rehearsal that is as realistic as possible, during which the go-live steps can be practised and previously undiscovered problems can be identified and solved. In addition to the activities to be carried out, the cut-over plan also contains provisions in case not everything goes according to plan: these contingency plans describe the measures to be taken to minimise risks and to remedy any conceivable problems during the go-live. The golden rule is never go live without carefully laid out contingency plans! Last but not least, every cut-over plan includes the go/no-go decision: at a meeting of all important project members and stakeholders, a final decision is made (and recorded) on whether to go ahead or stop the go-live. 3.6.6 Phase 6: Run After the successful go-live, the run phase begins. The first step is to stabilise the new system landscape. The hypercare phase is intended to prevent system failures and to 3.6 SAP Activate: The Better ASAP 93 overcome startup difficulties. The team then focuses on maintaining the quality standard achieved and successively implementing improvements. On the user side, a distinction is made between normal end users and key users (SMEs), which take care of solving application problems in the company.

These problems can be of various types: authorisation problems, incorrect user roles or deficits in training (also jokingly referred to as “the problem is in front of the computer”). Of course, they can also be configuration or data errors that were not noticed during the tests. The key users take care, for example, of carrying out an initial problem analysis and—if they cannot fix the issue themselves—forwarding it to the right places for rectification. These are the main activities in the run phase: • Support for users • Solving operational problems as they arise • Definition of future functional improvements and extensions Last but not least, we would like to give you an overview of all SAP Activate phases and the associated activities (Figs. 3.7 and 3.8). Note: Regular Updates of the SAP S/4HANA Cloud Solutions The SAP S/4HANA Cloud solutions are regularly updated and extended. In systems based on SAP S/4HANA Cloud, Essentials Edition, an update is automatically installed every quarter. For SAP S/4HANA Cloud, Extended Edition, updates are provided every 6 months and must be installed after 2 months at the latest. These changes are not at all comparable with classic upgrades in terms of the effort required for testing and configuration adjustments. This is where the great advantage of a completely standardised solution comes in, which works without modifications and extensions. 3.7 Support Tools Provided with SAP Activate With SAP Activate, SAP offers a completely integrated system consisting of meth- odology, best practices and guided configuration. In addition, SAP Activate is integrated into the SAP Solution Manager as a central landscape management system. With the SAP Model Company, a preconfigured SAP S/4HANA configura- tion is available (at extra cost). In the following, we will introduce the individual tools. 3.7.1 Roadmap Viewer The Roadmap Viewer offers Implementation Roadmaps which are arranged according to categories and solutions. These Implementation Roadmaps provide an overview of the projects and the tasks, activities and deliverables. The selected roadmap can be adapted so that company-specific activities can be added. It can also be used as a work breakdown structure and transferred to the SAP 3.7 Support Tools Provided with SAP Activate 95 Solution Manager to be used there as a starting point for project planning and execution. The Roadmap Viewer can be found at https://go.support.sap.com/ roadmapviewer. There are two generic roadmaps: 1. SAP Activate Methodology for New Cloud Implementations This roadmap is intended for public cloud projects. 2. SAP Activate Methodology for Business Suite and On-Premise This roadmap comes in two versions: an agile and a waterfall version. The roadmap is intended for on-premise projects. In addition, there are 11 further roadmaps, which are solution-specific: 1. SAP S/4HANA Cloud, Essentials Edition 2. SAP S/4HANA Cloud, Extended Edition 3. SAP SuccessFactors (cloud) 4. SAP Service Cloud 5. SAP Data Warehouse Cloud 6. Intelligent Spend Management (cloud) 7. SAP Analytics Cloud 8. Hire to Retire (cloud) 9. Transition to SAP S/4HANA (on-premise) 10. Transition to SAP BW/4HANA (on-premise) 11. S/4HANA Upgrade and Product Integration Roadmap (on-premise) It is also possible to download the information as a compressed archive. The ZIP file contains a work breakdown structure in Microsoft Project and XML format. In addition, an .xlsx file (Microsoft Excel) is supplied, which contains explanations of the WBS entries. The supplied XML file contains the same informa- tion as the work breakdown structure in Microsoft Project format but offers the possibility of integration (upload) into SAP Solution Manager 7.2. This makes SAP Solution Manager the central project management tool. The Roadmap Viewer contains a number of accelerators. The accelerators represent an extensive collection of useful documents, sorted by project phases and working groups. These include questionnaires and templates for the preparation phase, Microsoft PowerPoint slides and checklists. There are also links to blogs and websites with further information. SAP Best Practices: It’s All About Making the Right Choice Overall, the amount of information provided is impressive; some might even say overwhelming. However, it is not always easy to find the rightinformation for one’s own project, and in most cases, it must be adapted to one’s own needs. Nevertheless, the Roadmap Viewer provides a variety of useful and helpful tools to successfully manage the SAP S/4HANA project with the SAP Activate methodology. Familiarising oneself with the Roadmap Viewer at the start of a project is certainly time well-spent. 96 3 The SAP S/4HANA Project: How It Should Be https://go.support.sap.com/roadmapviewer https://go.support.sap.com/roadmapviewer 3.7.2 SAP Best Practices Explorer The SAP Best Practices Explorer is the central entry point for all SAP Best Practices and Rapid Deployment Solutions (RDS). SAP Best Practices contain all necessary information to model and use standard business processes in SAP. Rapid Deploy- ment Solutions contain preconfigured business processes that can be executed immediately. The SAP Best Practices are related to the SAP Model Company approach: specific content is imported into an existing system, together with the necessary data, customising, etc. This makes it possible to set up a system with standard processes that can ideally be adopted by the customer in his industry without any major changes. The advantages are obvious: customers can implement SAP S/4HANA faster and model business processes in a shorter time. There are country-specific solutions which are adapted to the legal particularities in the respective country. After activating the SAP Best Practices solution, the configuration can be extended and changed as before using transaction SPRO. It is important to use the Administration Guide for SAP Best Practices, which describes in detail how to set up the system configuration with SAP Best Practices: https://help.sap.com/viewer/ S4HANA1909_AdminGuide. Note: Integration of SAP Solution Manager 7.2 with SAP Best Practices As of SAP Solution Manager 7.2, it is possible to import SAP Best Practices. Each SAP Best Practices package contains process and configuration content, such as process diagrams, test scripts and configuration recommendations. These packages are continuously adapted to new SAP S/4HANA versions. The SAP Best Practices Explorer is therefore used in the discover and prepare phase and provides support in selecting the appropriate best practices for the respective project. SAP Best Practices can be activated in the development system using the SAP Solution Builder. The configuration is then distributed via transports to downstream systems (QAS and PRD). 3.7.3 SAP Model Company The SAP Model Company, a combination of SAP Best Practices, which together cover most standard processes of a “model company”, has been in existence since 2017. SAP Model Company is a “ready-to-run solution” consisting of business content (data), ready-made solutions and accelerators, such as test data and test scripts. It can be thought of as a collection of best practice building blocks that together create a fully functional environment that covers the core processes of a company. 3.7 Support Tools Provided with SAP Activate 97 https://help.sap.com/viewer/S4HANA1909_AdminGuide https://help.sap.com/viewer/S4HANA1909_AdminGuide The simplification compared to the best practice approach is that you don’t have to decide for yourself if it fits and is necessary for your project. The SAP Model Company package is fully configured—a selection is no longer possible at process level but only at business unit and industry level. On the other hand, one loses flexibility in defining the project scope, since it is not possible to selectively include or exclude individual processes. The SAP Model Company comes preconfigured for 17 industries and comprises 12 business areas (lines of business, LoB), but once you have chosen a model company, the content cannot be changed. You can only make adjustments in the Project System after you have imported the Model Company. SAP Model Company Packages exist (as of summer 2020) for the following sectors: • Agribusiness • Airline Back Offices • Automotive • Chemicals • Consumer Products • Core Retail • Defence Logistics • Fashion and Vertical Business • High Tech • Industrial Machinery and Components • Integrated Digital Banking • Integrated Utilities • Mill Products • Mining Production and Execution • Oil and Gas • Pharmaceuticals • Trade Management for Consumer Products • Utilities for Regulated Markets The following divisions are covered by SAP Model Company Packages: • Billing and Revenue Innovation Management • Connected Assets • Connected Manufacturing • SAP Customer Experience • SAP EWM for Industries • Finance • Human Resources • Logistics Execution • Multinational Corporations • Research and Development/Engineering and Sustainability • Shared Services 98 3 The SAP S/4HANA Project: How It Should Be • Supply Chain Planning • Wholesale Distribution The SAP Model Company concept is arguably the most successful innovation in the field of implementation methodology and tools in recent years. It has consider- ably reduced complexity and thus the time required as well as the investment (time- to-value) and is the first choice for many customers for their implementation projects (Greenfield). The advantages lie in five core areas: 1. The initial definition of the project scope and the quality of the associated effort estimates is considerably better and more resilient. It is a solid basis for business case and budget planning! 2. The project duration will be reduced drastically in most cases. 3. The process modelling is much more closely aligned with the SAP standard, which pays off due to lower development costs and, in the long term, lower adaptation costs when importing newer software versions. 4. Decision-making in the project is accelerated (which in turn saves time and money), as it is possible to take SAP standard process settings as a starting point and guideline. 5. The process and landscape design is “future-proof”, i.e. it is based on SAP’s roadmap and future developments. The big advantage of the Model Company compared to individual accelerators is its integrated, out-of-the-box approach: the model company system ensures that the different parts of the business fit together. As mentioned at the beginning, the biggest challenge in an SAP project is the complexity in technical, process and organisational terms. An SAP implementation is a huge effort for any company and—as the number of failed projects illustrates— an enormous risk. The implementation methodology makes a big difference when it comes to reducing complexity and making risks more manageable. Errors will always happen, but the number and severity of errors can be reduced. Sound, forward-looking planning allows you to react earlier to avoid the worst consequences of wrong decisions. Generic approaches, such as PMI or PRINCE2, are the basis of good project management. SAP-specific implementation models like SAP Activate build on these and offer highly specialised tools for their designated purpose. SAP has invested enormous amounts of time and resources in the SAP Activate implementation method as the successor to ASAP and is continuing to push ahead with updates and refinements. Roadmap Viewer and SAP Best Practices contain concentrated SAP know-how that can be used in a targeted manner to accelerate projects and make decisions for solutions that are as close as possible to the SAP standard. 3.7 Support Tools Provided with SAP Activate 99 The limits of SAP Activate are reached, when the customer landscape leaves the SAP world. As soon as customers connect their SAP systems to third-party systems—and this is the case for almost all SAP customers—SAP Activate support stops. Here, customers depend on the support of their software partners to identify and solve problems that may arise after implementation at an early stage. For most customers, this is a big challenge, because for them, it does not matter whether it is SAP software or third-party software—the entire landscape has to work together. As a projectmanager, using SAP Activate you have a good methodology to manage and control the SAP project deliverables. Keep in mind that it is the business critical non-SAP systems linked to your SAP landscape, which you must keep a close eye on as well. 100 3 The SAP S/4HANA Project: How It Should Be The SAP S/4HANA Project: How It Is 4 From dream to nightmare, in this chapter, we return to the hard ground of reality. There is probably no complex SAP S/4HANA project that runs without problems. However, most of the time, the mistake is not in the (SAP) system: no, the problems are home-made, overlooked or underestimated by those running the project! Despite (supposedly) careful planning and a methodical approach, there will always be occasions when your project is in a tailspin. This chapter draws your attention to the pitfalls that occur most frequently in practice. In terms of content, we will mainly deal with “new” SAP S/4HANA projects. These projects use SAP S/4HANA as a basis, SAP HANA as a technology platform and SAP S/4HANA projects with agile parts. We are aware that currently, a large number of SAP implementations based on SAP ERP Central Component (SAP ECC) are still productive and will not be converted or migrated to SAP S/4HANA anytime soon. Besides, there are ongoing projects that use Accelerated SAP (ASAP) as a project method and SAP ECC or its predecessor releases or hybrid implementations (mainly because the functionality of SAP S/4HANA has not yet reached the full scope of the “old” SAP Business Suite). In this chapter, we refer to the phases of the SAP Activatemethod introduced with SAP S/4HANA, which you got to know in Chap. 3, “The SAP S/4HANA Project: How It Should Be”. There, we have already discussed similarities and differences between SAP Activate and ASAP. In this chapter, we discuss mistakes that frequently occur during the project’s course in the context of the phase in which they can have the most serious impact on your project’s success. Think creatively before starting the project and before each project phase about how you can avoid the respective stumbling blocks—or at least a large part of them. You will find additional support in Chap. 6, “Project Planning, Control and Quality Assurance”. An SAP S/4HANA project is not an IT project in the classic sense but rather a transformation project that will change processes, business models and company organisations in the long term. If you succeed in anchoring this special feature in the # The Author(s), under exclusive license to Springer Nature Switzerland AG 2022 D.

We have already provided an insight into the individual phases of SAP Activate in Chap. 3, “The SAP S/4HANA Project: How It Should Be”. 4.1 Phase 1: Discover (Or Explore Possibilities!) Determine the Project Scope: This phase before the actual project start is new in the implementation methodology of SAP software—not only in name but as an additional important phase. Even before the project’s actual start, this phase provides methodical support in preparing for the project. The transition of the project from (internal) sales (every project has advocates* and opponents* and must first assert itself) into the operative phase takes place here. This handover from sales to delivery is the first part of this phase. Every project of the size of an SAP S/4HANA transformation project requires thorough preparation in terms of technical aspects and (and perhaps above all) in the involve- ment and conviction of important decision-makers and the coordination of the project’s scope. Equally important is the definition of what should not be part of the project. If these decisions are made, documented and approved here, annoying discussions and shifts of planning and budget can be avoided during the later project implementation. Thus, this phase’s results are the documented handover of the project to the executing project organisation and the definition and acceptance of the project scope. What Works and What Does Not (Yet) Work? In contrast to “conventional” SAP projects based on SAP Business Suite, where the full functionality is available, SAP S/4HANA projects are currently still somewhat limited in certain functional areas. There are many new possibilities in finance and controlling, and we are also able to find and use many tried and tested solutions. In some other areas (e.g. SAP Supplier Relationship Management, SAP SRM, or SAP ERP Human Capital Management, SAP ERP HCM), SAP S/4HANA does not (yet) offer the full range of functions. Here, a clear distinction must be made from the outset in the scope definition of what can and cannot (yet) be done. Another important aspect is to have found one or more project sponsors at this early stage. There will always be discussions about the usefulness of decisions. Therefore, it is important to have stable decision-makers behind you. You, as a project manager, are, of course, already in the “driver’s seat” at this stage. However, you will not bring the majority of the project organisation on board until the next phase. 102 4 The SAP S/4HANA Project: How It Is 4.2 Phase 2: Prepare (Project Preparation) Laying the Foundation Stone: The decision for the SAP S/4HANA project has been made. In the preparation phase, you now lay the foundation for successful project implementation: set goals, plan times and resources, set up the project organisation and define the infrastructure for project work. You pay particular attention to the coordination and communication of the project within the company. So far, so good! In these sections, we will introduce you to the challenges you most frequently face when planning and preparing the project. 4.2.1 Official Project Start Projects on the scale of an SAP S/4HANA project usually affect (or perhaps better “impact”) several parts of your company and a large number of employees in the respective divisions. As the project moves forward, more and more new external consultants will be involved in the project and will often occupy their new workplace in the company for some time. There are many changes—and these should be well prepared and communicated. You also have to make sure that everything you are planning now is implemented accordingly. Once the project team is ready to start, there is a joint project kick-off. The starting signal for the project has been given! 4.2.2 Simplification Through Solution Modules One of the biggest (and best) innovations in SAP Activate is providing ready-made solutions in the form of “guided configuration” and the delivery of ready-to-run business processes. On the one hand, this facilitates (and shortens) the implementa- tion and, on the other hand, sets stricter standards. See Chap. 3, “The SAP S/4HANA Project: How It Should Be”, and Chap. 9, “Project Support Tools”, for more information. For you, as project manager, this means (even more so than perhaps in an SAP ECC project) to pay attention to the use of this standard functionality. 4.2.3 Planning the Project I Want It All and I Want It Now: It is not uncommon for you to be under great pressure of expectations as early as your SAP S/4HANA project planning stage. If you are responsible for a project in your company, this pressure comes from your management. If you work as a customer consultant, the pressure comes from the client. The following examples should illustrate the difficulties that lurk in this project phase: 4.2 Phase 2: Prepare (Project Preparation) 103 • Stress from within your own camp (internal projects) The “go” for a new project is often associated with theclear expectation that the specified introduction deadlines will be met and, if possible, even undercut. Carried by exuberance and the lack of experience with transformation projects, the deadline is not subject to a qualified review. Quiet doubts are suppressed. Nobody wants to expose themselves and admit that the timetable could be far too ambitious. If you have already had successful SAP projects in your company, the pressure of expectations may even increase (“it can’t be that difficult, we managed it the first time around”). However, we advise caution here: we are talking about a completely new technological platform with new possibilities! (The Simplifica- tion List, which describes the process simplifications of SAP S/4HANA com- pared to SAP ECC, has over 1000 pages for the current 1909 version—and these changes will definitely make your SAP S/4HANA project a completely new project.) • Wishes of the customer (consulting projects) In the battle for a contract, many a supplier has been tempted to make unrealistic promises. Based on the customer’s requirements, which are often not clearly defined in the offer phase, you have to make statements about budget and deadline. There is the risk of overlooking possible problems in favour of future sales expectations. It is often impossible to meet the promised deadlines with the agreed budget. In both cases, you, as the project manager, are facing your first challenge. Do not allow yourself to be lured into the trap of aligning the project plan too optimistically with a target date. In general, many planning errors result from the effort to meet given deadlines (even if they are unrealistic). • The availability trap If the project complexity and/or the project staff’s availability are assessed unrealistically, the deadlines cannot be met from the outset. For example, employees are often scheduled for 5 days a week for the whole year. The realisation that a summer holiday is also due this year does not set in until June. • The optimism trap Estimates of project costs are too optimistic, too superficial or even wrong. They, therefore, do not provide a reliable basis for project implementation. • Planning too rough There is not enough detail in planning: the planning is not based on milestones, and critical paths are not defined. • Incomplete planning The planning is not complete: work packages are missing or are not assigned to the project phases in a logical order. • Insufficient communication Plans are not communicated sufficiently to project staff, stakeholders, specialist departments and adjacent projects. 104 4 The SAP S/4HANA Project: How It Is • The blinders effect Potential risks are insufficiently evaluated. The plans do not contain measures to avoid or minimise risks. For example, it is not considered that employees may be assigned to other projects or their specialist department and thus have only limited availability for the project. • Lack of quality assurance No quality assurance procedures are planned. It is unclear who carries out quality checks, when and on what basis. In complex projects, however, an independent assessment by external auditors with experience and sensitivity is helpful. • Too few or too many buffers If deadlines are tight, planning is done without or with too little buffer. Planning without a time reserve endangers the project. But the opposite is also a problem: excessively generous buffers result in a certain carelessness and make the project more expensive. • SAP S/4HANA release cycle Currently, the SAP S/4HANA system is in a very stable state but is being functionally developed further. You will almost certainly be upgraded to a new release during your project. Time is needed for both the technical conversion and the necessary tests, which you will lack in the end without long-term planning. If you are prepared for the many challenges waiting in such a complex project as an S/4HANA introduction, you can elegantly avoid many pitfalls. 4.2.4 Project Organisation and Project Resources In this section, we would like to show you the most important pitfalls you may face when setting up the project organisation and nominating project staff. The Most Important Resource—Qualified Personnel: The establishment of an efficient project organisation and project structure and the staffing of the teams with qualified employees require a lot of attention and care. If roles, responsibilities and procedures are not clearly defined projects can get into a tailspin right from the start. Taken from Project Life: In the practical example that you got to know in Chap. 2, “What Makes an SAP Project So Different?”, a competition for the limited SAP process and project management skills develops, for example, because the interests at the global and local level are not always congruent. Besides that, the new SAP S/4HANA platform has split the world of SAP experts into two camps for the time being: on the one hand, SAP S/4HANA expertise and on the other, the currently still relatively large number of SAP consultants with SAP Business Suite Certification. There is enough work available for both groups: for your SAP S/4HANA project, you need a 4.2 Phase 2: Prepare (Project Preparation) 105 considerable number of SAP S/4HANA consultants—and those with extensive project experience are still relatively rare. When setting up the project organisation, ask yourself who the people are with whom you want to make your project successful. This does not only apply to the project team in the narrower sense because the project organisation includes all the people involved in the project (management, steering committee, stakeholders and specialist departments). When setting up a project organisation as well as during the course of the project, the following areas can cause particular headaches: • The others are always responsible The responsibilities of all persons involved in the project are not defined and agreed upon within the company. There is no overwiew, which clearly describes who is responsible for which tasks in the project, e.g. a RACI matrix (Responsi- ble, Accountable, Consulted, Informed) (see Sect. 6.3.1, “Guidelines for a Successful Project Control”). • Unclear decision-making powers In an SAP project, decisions have to be made, which involve personnel, organisational and process-specific changes. If it is not clearly regulated, who in the company is authorised to decide? This lack of regulation leads to delays in decision-making. In the worst case, massive acceptance problems arise during rollout. • The right people are missing The availability of qualified specialists at the right time is not guaranteed. For example, a project manager with a lack of experience in complex SAP projects and/or lacking leadership qualities is deployed. The project manager of an SAP S/4HANA project should also have at least participated in the successful imple- mentation of SAP S/4HANA in a leading position. Knowledge gained through trainings is helpful here but not sufficient. The search for suitable candidates is often difficult and takes much time, during which the project cannot move forward. • Conflicts of tasks in the case of parallel staff deployment Employees are often only assigned to a project on a part-time basis to keep in touch with the practice and with colleagues in the department, which can be quite useful. However, these employees then find themselves in a permanent conflict between the project’s demands and the day-to-day business of their traditional tasks. There is the danger that they will be scheduled several times. • The chemistry is not right: disagreements in the team Not all the people involved are compatible, because in addition to technical qualifications, interpersonal factors also play an important role in the project’s success. • No common objectives The project staff’s personal goals and the company’s responsible persons do not coincide with the project’s goals, e.g. concerning the duration of thecooperation 106 4 The SAP S/4HANA Project: How It Is in the project, the career interests of the project staff and the different interests in the specialist departments. • Fears about the future Sometimes, project staff’s previous jobs are filled by others, making their reinte- gration into specialist functions more difficult. Worries about their future job can harm their willingness to perform. • Conflicts of competence There are conflicts between external consultants and long-established process owners or between supervisors of legacy systems and the SAP S/4HANA project group. Resentment of advocates of the status quo towards the new is widespread and should not be underestimated. • Unclear expectations You have failed to discuss clearly with your staff what you expect from them from a professional and personal point of view before the project begins. • Agile sub-projects Agile sub-projects are increasingly used in SAP S/4HANA projects (especially in software development). Here, other methods and project management approaches are necessary. Experts for this are (still) rare and must be involved at an early stage. The project organisation’s structure is a foundational and crucial issue because, normally, it is valid for the whole project duration. The time invested here usually pays off at the end of the project. 4.2.5 Provisioning the Infrastructure Creating the Right Framework: Despite the obstacles mentioned in the previous section, you have managed to put together a highly qualified and motivated project team. However, there is still unrest, and the work is not progressing as planned in the project plan. What happened? If logistical and technical prerequisites for successful project work are not created in time, daily work delays will occur. Instead of devoting themselves to their tasks in the project, the employees are busy chasing after important work equipment. The resulting dissatisfaction and frustration endanger the progress of the project. The following examples, from our years of experience, may sound familiar to you: • Lack of workspace Employees cannot work because there are not enough workplaces available. • No system access Employees cannot work because they do not have system access or the IT equipment has not been ordered in time. This may be because the employee 4.2 Phase 2: Prepare (Project Preparation) 107 responsible for purchasing not know which hardware to order—or he / she was simply on holiday. • Systems missing Employees cannot work because the system landscapes (SAP system or legacy systems) are not available for customising, development or testing. Cloud Usage: With SAP S/4HANA, SAP’s strategy has developed even more clearly in the direction of becoming a provider of cloud solutions. Many of the new components that are no longer part of the digital core, such as SAP SuccessFactors, SAP Ariba or SAP Fieldglass, are now only available as cloud solutions. SAP S/4HANA still offers the possibility to run the software in your own data centre; however, software innovations are available faster in the public cloud. When you are leveraging SAP S/4HANA Cloud (be it extended edition, or essentials edition), SAP is not only the software manufacturer, but also the service provider—which means you have another “player” in your project. Although this provider is (usually) very service-oriented, it processes tasks according to a catalogue and with experts not directly assigned to the project. Special expertise and increased attention are required here to avoid costly delays. 4.2.6 Communication Within the Company Marketing is Everything and Everything is Marketing! Coordination of the project and publicising the project within the company should go hand in hand. However, experience shows that failures in this area can lead to considerable misunderstandings and difficulties: • Unclear project objectives The project objectives are not communicated to all participating or affected organisations in the company. There is no common understanding of project expectations, urgencies and priorities. Some of those directly involved do not know what to expect during and especially after the project. • Boundaries are missing Boundaries that define and clearly communicate the project’s scope and—most importantly—what will not be part of the project are missing. Especially for companies that already operate a complex SAP landscape, the SAP S/4HANA project will only replace part of it. A clear demarcation is necessary here. • Lack of involvement of the specialist departments Specialist departments do not participate. As a consequence, the departments affected by the project do not feel obliged to support the project. This can lead to permanent disputes, making the project unnecessarily difficult, causing delays or even causing the entire project to fail. Without careful coordination within the company, conflicts regarding budgets and project resources can also be expected. 108 4 The SAP S/4HANA Project: How It Is • Lack of basics There is no statement of work defining the project’s content, scope, duration and budget. Sometimes such a document exists but is not accepted by all project participants. • The left hand does not know what the right hand is doing The project management fails to coordinate the content and technical aspects of parallel or sub-projects. Serious consequences for the project’s course are to be expected if the effects of parallel projects on upstream and downstream processes are recognised too late or ignored. Inconsistencies in process design or the system architecture can make a complete redesign necessary. Suppose you have not managed to reach a common understanding with your organisation’s leadership and other key parties in the company about the priorities of the SAP S/4HANA project and have not agreed on realistic timetables and budgets. In that case, at this stage, at the latest, you should make a recommendation not to continue the project. 4.3 Phase 3: Explore (Or Map Business Processes!) What Is Missed Here Is Hard to Fix Later! Now the project is taking off. The aim is to develop the best possible support for essential business processes. The starting point are the default templates that come with SAP Activate (templates to realise business processes and their implementa- tion). This content comes from the SAP Best Practices (these already existed in ASAP) and the solution implementation proposals. They are available as content for business processes and as content for migration and integration. So far, so good! The challenge is to align these offers with the company’s actual requirements (and thus our project’s requirements). Which requirements can be covered by default (hopefully quite a lot), and which cannot? In SAP Activate, we are talking about the fit-gap analysis (which was also already available in ASAP). The aim is to describe the solution: the business blueprint. Business Blueprint In the business blueprint, you lay the solid foundations for your SAP S/4HANA project. You design the future SAP system based on the business process requirements and decide on the system architecture. Errors and oversights in this phase put the project at high risk. Corrections in the later course of the project always mean additional work and, in many cases, delays. This makes it all the more important that you familiarise yourself with the pitfalls described in the following sections. 4.3 Phase 3: Explore (Or Map Business Processes!) 109 4.3.1 Business Process Requirements The development of business process requirements and their implementation in the new SAP S/4HANA system requires detailed corporate strategies for the coming years. Corporate Strategy as the Starting Point The business strategies and the processes derived from them are usually decided before the decision for SAP S/4HANA. If such strategies are missing in the project team or are not sufficiently understood, the following dangers for the project may arise: • Requirementsthat are difficult to meet The process requirements are not aligned with the SAP S/4HANA standard pro- cesses. It is not sufficiently evaluated to what extent the detailed process requirements can be mapped in the SAP S/4HANA software. No prototype will be created to demonstrate the SAP standard’s possibilities to the business departments for reasons of time and budget. Therefore, the desired processes are not executable in the SAP system or can only be implemented with a great deal of programming effort. • Missed opportunities: strategy and implementation do not fit The business processes described in the blueprint do not fit into the corporate strategy. • Processes get out of hand The process experts in the project develop their own “visions”, which are rejected once the coordination with the specialist departments takes place. • Old processes in the new system The process experts describe what they know, namely, the existing processes. In extreme cases, this can lead to extensive project effort and business processes being locked in or frozen for a long time. Especially when switching from SAP ECC to SAP S/4HANA, many of the new possibilities offered by SAP S/4HANA are not exploited. • Unclear requirements Business process requirements are not formulated precisely enough. To avoid false interpretations and misunderstandings during implementation in the SAP S/4HANA system, well-thought-out requirements that fit both the company and the SAP S/4HANA standard are necessary. • Incomplete documentation The documentation of the requirements does not contain sufficient details required for coordination with the specialist departments. • No coordination with the specialist departments There is no formal acceptance of the specialist departments’ new processes, for example, because business process managers are not involved in the decision- making processes. 110 4 The SAP S/4HANA Project: How It Is The business processes implemented in our SAP S/4HANA solution are the main deliverable of our project. For this reason alone, this phase is of particular importance. 4.3.2 System Architecture The definition of the process landscapes has significant impact on the system architecture. It is often forgotten (or underestimated) that the decision for an SAP S/4HANA system is also a decision for a new SAP architecture. Thus, many boundary conditions are predetermined, e.g. a client-server architecture of an in-memory database system or the programming languages to be used (still ABAP under SAP S/4HANA). Hardware as the Basis of Every SAP Project—Even in the Cloud: An unstable architecture jeopardizes the project: the specifics of the implemented SAP software scenarios have a great impact on the architecture and the costs. What are the pitfalls? • Miss-outs during the software selection process It is not absolutely clear which systems are upstream and downstream of the SAP S/4HANA system—or the selection is changed again and again. Often decisions on the whereabouts or replacement of systems not directly affected by the project are simply postponed or forgotten. Later in the project, such omissions lead to changes in the architecture, additional costs or adjustments to the project scope. • Re-inventing the wheel again and again The prerequisites that SAP has set for reference architectures are not adhered to. Instead of learning from the experiences of other projects, the participants design everything themselves, thus investing more time and money than necessary. Often only those functions that the consultants themselves know are implemented. Unknown functions are sometimes imitated (i.e. reprogrammed), although they are available in the standard system. Quality reviews performed by SAP Consulting can help as quality assurance in the project (or experienced consultants familiar with SAP S/4HANA functionality). • The interface planning is missing There are studies that in SAP S/4HANA projects, up to 50% of the budget is spent on integration. Nevertheless, the required integration scenarios (interfaces) are often unclear, althoughmuch money can be saved through well-thought-out planning, the use of integration platforms and standardisation. If the SAP S/4HANA solution is operated in the cloud, interfaces often become necessary across data centre boundaries. Projects must plan additional expenditure (e.g. coordination with the network infrastructure operators) to implement and test interfaces. 4.3 Phase 3: Explore (Or Map Business Processes!) 111 Freedom to Adapt the Software: One of the fundamental questions is how many new system architecture changes compared to the SAP S/4HANA standard are required/necessary. The various options for implementing SAP S/4HANA have different specifications. An on-premise implementation means the software is running in your own computer centre or with a computer centre operator of your choice, offering the greatest scope for adapting the software to your own needs. This form of implementation is well known from the SAP ECC environment. Whether you want to develop your own functionality or modify SAP S/4HANA standard code—anything is possible. And these possibilities are often very tempting. The situation is different with SAP S/4HANA Cloud. There are limits to enhancements, and modifications are simply impossible. The use of SAP’s “preconfigured” solutions for processes mapped as standard in S/4HANA is per- fectly adequate for smaller companies or companies with a standard process land- scape. For these customers, the use of SAP S/4HANA Cloud has great advantages. There is no obstacle to using the latest innovations with each new release. And the constant discussion about whether certain, cherished “special features” need to be incorporated into the new S/4 solution has been settled from the outset: it is simply not possible—full stop! However, foresight is required here. Even future requirements that deviate from the standard will not be realisable in S/4HANA Cloud, but only in external systems. 4.3.3 Project Standards and Procedures If you have not set standards for your project and disagree on how to proceed, you will not succeed. If standards and procedures are defined, but nobody follows them, you will also not succeed. Do you want to know what problems you may encounter? Here’s the scoop: • No stable project structure Project organisations, project methods and procedures are casually or even spontaneously changed. For example, tasks are reassigned, teams are regrouped, documentation and reporting structures are changed, or processing cycles are restructured. As a consequence, you can expect additional training effort and a lack of transparency. • Project management tools are not used Tools for planning, management, documentation and controlling are not used to a sufficient extent or not at all. • Unclear communication channels Communication is the key to success, and yet communication and escalation channels are often not clearly defined as mandatory. There are no fixed dates for status meetings, steering committee meetings or communication with 112 4 The SAP S/4HANA Project: How It Is stakeholders. This leads to uncertainty and mistrust at all levels regarding the status and impact of the project. • Lack of documentation standards Standards for the documentation of processes and system solutions (configura- tion/programming) are missing. • Documents are lost There is no filing structure for documents, which significantly reduces retrievability. In other words, you can't find what your are looking for. • Knowledge transfer not organised No system is used for knowledge storage and knowledge transfer. Alternatively, there may be a system, but not all project staff have been trained in its use. • Moving away from the SAP standard Special requirements that can be mapped in the standard but are “much nicer” if developed in-house can often be implemented on-premise, but they often cannot be implemented in the cloud. Certain project standards recur timeand again. In such cases, the project team can use the experience from previous projects and external project staff. 4.4 Phase 4: Realise (Or The Implementation) The Realisation Phase: A Long-Distance Run Even if you have gone through the previous phases strictly according to project management rules and almost without a blemish, you are still far from reaching your goal. In the longest and most difficult phase of a project, the number of errors and omissions naturally increases. In this section, we would like to show you which errors can occur in the areas of project management and control, the configuration of SAP S/4HANA systems, tests, data migration and change management. For They Know Not (Yet) What They Do: Before we delve into the details, we would like to address one of the most common omissions that affect all the tasks mentioned above during the realisation phase. As you enter this most complex phase of the project, the number of project staff increases—new colleagues join your project. The new team members’ training and the team’s preparation for the realisation phase tasks are often underestimated. Therefore, take new team members by the hand! 4.4 Phase 4: Realise (Or The Implementation) 113 4.4.1 Project Management and Control An important success factor is the management and control of the project by the project leadership and the project management office (PMO). Deficits in expertise and leadership are immediately reflected in the progress of the project. Here are two practical examples: • Professional competence as a stumbling block The project manager considers himself/herself the best specialist. They try to turn visions into reality by describing and specifying the new processes. Project staff is thus forced into a supporting role and lose their initiative and drive. • Loss of confidence One party (either the consulting company or the client) changes the project manager without consulting the partner in a project. Such behaviour can lead to anger and mistrust in the project. • Deficiencies in leadership behaviour The project manager has professional deficits and/or weaknesses in communica- tion and leadership behaviour. He/She: – Cannot delegate – Takes over critical tasks him- or herself – Is too deply involved in detailed tasks – Does not understand how to promote team building • Lack of professional competence in the project management office The staff in the PMO are not sufficiently qualified for their central task in the project. For example, there is a lack of business management competence to assess project situations correctly. • Lack of soft skills in the project management office The PMO staff cannot detect atmospheric disturbances and the resulting risks for the project’s progress at an early stage. • Controlling becomes an end in itself Project management develops a life of its own: using tools and gathering project data and key figures without recognising and initiating necessary measures from the controlling mechanisms does not help the project. • The project status is always green—no matter what The transparency of the project status leaves much to be desired. There is no honest status communication, information is suppressed, and problems are minimised. The left hand does not know what the right hand is doing. • Lack of consequences Deadlines are missed without action being taken. There is no objective evaluation of partial results and implementation steps. Identified weaknesses are ignored or not consistently pursued and remedied. • Teams work in silos. Individual teams devote themselves to team-specific subtasks, whose results cannot be integrated and corrected later or only with great effort. 114 4 The SAP S/4HANA Project: How It Is • Skills are missing or lost Skills are often missing or lost; this problem can have many faces: – It is only in the implementation phase that it is recognised that internal and external project staff lack important know-how. – Central competencies are lost because indispensable employees leave the project prematurely. – Departments withdraw their staff, employees resign or are promoted too early, and external consultants are dismissed. • Project reviews do not take place – Project reviews are not carried out at all, or not carried out with the necessary care. The longest phase in a project also requires staying power and a consistent focus on what is important in the project. 4.4.2 Configuration of the Systems In general, your originally estimated and planned expenditure is put to the test in this phase. This is the time when realistic planning and experience really pay off. The configuration of the SAP S/4HANA system is based on detailed descriptions of the process steps as they are to be carried out by end users. Additional Work for Customising? The realisation phase now shows to what extent the often optimistic ideas in planning the expenditure (in phase 1) and the detailed description of the process requirements in the blueprint (in phase 2) can be implemented with as little program- ming effort as possible. So what can happen when customising the SAP system? • Additional expenditure due to lack of knowledge about the SAP standard To solve the new processes only via customising in the SAP standard is the dream of all project clients and the project management! It often looks like this: the process steps cannot be implemented in customising, and the programming effort increases. The causes for the increase are often a lack of detailed knowledge about the possibilities in the SAP S/4HANA standard when defining the processes and the specialist departments’ lack of willingness to tread new ground. • Process Creep The processes defined at the beginning of the project are moving further and further away from the SAP standard. One reason for this may be that those responsible are trying to avoid permanent and exhausting fights with the specialist departments in the interests of project progress. • Requirements never end A weak or even missing requirements management leads to the constant addition of new requirements. This can make it exponentially more difficult to adhere to 4.4 Phase 4: Realise (Or The Implementation) 115 the project duration and the project budget. The project leadership often neglects setting deadlines to submit requirements or neglects to communicate these deadlines within the company. • Financial targets and budgets were too ambitious The expenditure shown in the original plan is so tightly calculated that there is hardly any room for additional requirements. Nevertheless, if you accept new requirements, this will increase your effort, budget and project duration. Perhaps the cost estimates were also too optimistic in the preparation phase, e.g. because the effort involved in error correction was underestimated. • Superficial requirements analysis If the requirements analyses are missing or superficial, you risk additional expenses and integration risks for process flows and system architecture. • Changes without approval The requirments approval process, if it even exists, is not strictly adhered to with increasing pressure towards the end of the implementation phase. Changes are then often implemented without project management’s awareness or approval. This phase also shows whether all the good ideas can be implemented in the system. At this point, creativity is sometimes key for a successfully realisation. 4.4.3 Testing Your System on the Test Bench An important pillar for completing the new system is testing all components, including testing across SAP S/4HANA boundaries. Ultimately, the decision to go live with the new system depends on the results of the tests. A test’s significance stands and falls with the test employees’ professional and methodical qualifications and well-founded and realistic test planning. Unfortunately, these requirements are not always met in real-life, but instead, you will be confronted with the following situations: • Underestimatingthe importance of testing The importance of the tests and their complexity and thus the preparation time are often underestimated. Under time and budget pressure, no dedicated test team is then established. Instead, an attempt is made to manage the test only with virtual part-time resources. • Lack of testers There is a general reluctance among the specialist departments to make their best employees available for test tasks and to release them from their operational activities for the test period. • Shortcomings in test planning and test methods There is no successful test without specialist knowledge: there are shortcomings in test planning and using modern test methods and test test tools, leading to 116 4 The SAP S/4HANA Project: How It Is insufficient test coverage. Much is left to chance, as well as the personal skills of the staff overseeing the test, which usually negatively impacts test coverage. • Test environment missing The test environment (in the SAP S/4HANA system and upstream/downstream systems) is not always available when starting the test. The underlying causes can be manifold. For example, master data has not been loaded in time, or it was neglected to order test machines in time. Potential system limitations are not taken into account with foresight during test running in parallel. • No coordination of the test strategies The test strategies and test coverage are not coordinated with the relevant company units before starting the implementation phase. • Too much test effort Often there is a lack of understanding for test optimisation on the part of the company units; everyone wants to test the overall processes. This would lead to a massive increase in testing efforts, e.g. in cross-border implementations. • Tests happen too early Due to the deadline pressure towards the end of the realisation phase, tests are started, although development is still in progress. • Missing test data The “real” data, i.e. the data transferred from the legacy systems in live operation, is missing for the test cycles—possibly because the data migration is not yet ready or because the planning does not fit. Testing is done with “synthetic” data. Often, however, not all possible data constellations can be tested in this way, and the nasty surprise follows after the actual data migration—often too late. Testing the solution is one of the most exciting stages in the project. Now you see whether everything works as intended. The (successful) test is also essential to minimise the risk of going live! 4.4.4 Data Migration Data Migration: An Underestimated Task In Chap. 2, “What Makes an SAP Project So Different?”, we have already complained that data migration often does not receive the necessary attention. Unfortunately, the effort required to transfer the data to the new systems is often underestimated. Remember that a successful data migration requires a team of experts who work parallel with the system configuration. The key risks associated with data migration are as follows: • Lack of qualifications It is not recognised how much expertise is required for data migration, presenting the risk that the employees deployed do not have the professional qualifications for this task. The transformation of old data into the new SAP data structure requires a thorough knowledge of the business processes and business data and 4.4 Phase 4: Realise (Or The Implementation) 117 your new SAP S/4HANA system components. Because configuration and data migration activities overlap, there is a risk that your top process experts will be deployed primarily for process design. The migration from SAP ECC to SAP S/4HANA is a big job because the data model has changed fundamentally. • Data mapping Data mapping activities are not seen as an iterative process parallel to system configuration and are therefore initiated too late. • Garbage Out, Garbage In The cleansing of old data before transfer to the SAP S/4HANA system is often not given the necessary attention and care. To believe that the migration to the new systems would solve all data problems always proves to be a fallacy. Existing problems are thus transported into the new system. • Data load programs are not tested Usually,there are large amounts of data to be loaded, which means highly automated data load programs are required. If you fail to create sufficient control mechanisms for the correct data load, you will inevitably run into productive operation problems. With the SAP S/4HANA Data Migration Cockpit, a highly sophisticated data migration tool is available with SAP S/4HANA. This tool is certainly no panacea for all possible migration scenarios, but it is a the best starting point. In Chap. 9, “Project Support Tools,” we will discuss this in more detail. A common reason why projects are not 100% successful is that many of the problems described here are linked to small mistakes, which are often not individu- ally recognised as problems during the project. Only with integrated testing across functions and systems can the new SAP S/4HANA solution’s proper functioning be guaranteed. 4.4.5 Change Management Heard it Through the Grapevine: An SAP S/4HANA project always entails changes in process flows that have a potential impact on business models and company organisations. This can lead to FUD (fear, uncertainty, doubt), a climate of insecurity and fear of retrenchments. A lack of transparency and guidance are the ideal breeding ground for rumors and concerns. Open or hidden adversity or slow-walking can be the result. There is no way around proactive change management. If you fail to involve all affected employees and managers in the transformation process, you will jeopardise your project’s acceptance. What are the most common pitfalls that you should avoid? • Lack of coordination of project objectives Project objectives are not coordinated with all business units. 118 4 The SAP S/4HANA Project: How It Is • Question marks in their eyes: regular updates are missing Management and employees are not regularly or openly informed about project results and impacts. • Unsuitable training concept The training concept is not specifically geared to the knowledge needs of the respective employee groups. Change management is perhaps the most underestimated topic in transformation projects. Each of these projects leads to many changes in processes, organisation or the cooperation between people and departments. If the workforce is not adequately prepared and brought on board, conflicts and rejection are inevitable. 4.5 Phase 5: Deploy (Or Preparation for Going Live) Preparation for the Go-Live You still have the last few yards ahead of you, and then the big goal, the go-live, will be achieved. Now you must make the final preparations for the production startup. The last go-live preparations include training future end users and planning the go-live. If you use SAP S/4HANA cloud, your colleagues from the large cloud providers’ support organisations, who are often not known by name, will be added. The necessary support processes must be clear, and the employees must be prepared. Here are the topics that must be addressed. 4.5.1 User Training In Chap. 3, “The SAP S/4HANA Project: How It Should Be”, you learned that training end users well is one of the key success factors in the SAP S/4HANA project. If the end users are well-trained, the support effort will be reduced, and you will avoid unnecessary friction because you will be able to recognise the users’ worries and needs and address them. But even during planning stage of your training curriculum, you may make mistakes which may come back to bite you later. This includes the following: • Who should be trained? Nobody really knows what the individual training needs are. • Insufficient training material The departments are not involved in the production of the training material. There is, therefore, a risk that the training material is too strongly system-related and not sufficiently process-and user-oriented. • Missing training systems 4.5 Phase 5: Deploy (Or Preparation for Going Live) 119 The training systems are not available in time, or the data in the system is not up to date. The users from the departments are the most important indicators for a successful project. Only when they are familiar with the system, the project can be successfully completed. 4.5.2 Going Live Get Ready: Get Set—Don’t Go! It is almost done: the start date is set, and all data migration activities have been determined. But wait: is everything really prepared? Possibly not, because one or the other activity may have been forgotten in your project: • Unfinished productive systems Setting up the productive systems takes more time than planned. • Missing interfaces The interface connections have not been agreed upon with all involved parties. • Inadequate quality assurance Quality assurance measures are not given the necessary importance or even fall victim to time pressure. • Testing has been neglected The final productive system tests (performance tests or stress tests) have not been thorough enough. • The data load takes longer than anticipated The time needed to load the legacy data is underestimated (possibly insufficient testing was done). • There is no master plan The cut-over plan is not complete or too imprecise and not agreed with all parties involved. Going live is the final milestone in every SAP S/4HANA project. Now is the time when it is decided whether the project is a success or a failure. It would be a pity if a major transformation project failed or had to be postponed just because of missing hardware or other “minor oversights”. 4.6 Phase 6: Run (Or Go-Live and Support) Last Check: Even when the decision to go live has been made, it is still too early to sit back and celebrate. It is important to avoid typical pitfalls: 120 4 The SAP S/4HANA Project: How It Is • Going live although critical errors have not been fixed The pressure of implementing on time leads to putting the system into production, although critical errors have not yet been eliminated. This, in turn, can lead to serious disruption and stress in the production system. • Non-functioning support systems Neither the internal nor the external support structure is fully established for going live. If the support is not provided efficiently and competently, especially at the beginning, this negatively impacts the employees’ acceptance of the new system. • Loss of competence Employees with project-critical skills leave the project too early and are no longer available for the stabilisation phase or further support. • Downtimes are exceeded and no precautions were taken The downtimes during the system changeover for going live are underestimated and therefore need to be extended, leading to serious impairments in the handling of business processes. The handling of business processes during downtime is not sufficiently coordinated within the company. • Incomplete documentation The documentation of the processes and system solutions is not complete or not detailed enough for going live. This makes error analysis and error correction considerably more difficult. Before we close Pandora’s box again and devote ourselves to the project staff in Chap. 5, “The Underestimated Success Factor: People”, we would like to present our personal “hit list” of typical pitfalls. 4.7 The Top Flops in the SAP S/4HANA Project Mishaps, Bad Luck and Epic Fails: We have compiled the best of the best of mishaps, bad luck and epic fails from our practical experience. Do not do what is described in the following sections! 4.7.1 Pitfalls Throughout the Project You underestimate that an SAP S/4HANA project is not a simple IT project but has serious impacts on processes, jobs and organisations. You do not ensure that project management and project staff meet the complex SAP S/4HANA project requirements. The problems include both technical deficits and weaknesses in management and communication behaviour. You have not agreed on the project objectives with all business units concerned and do not inform them of the results. There is no clear requirements management process. You underestimate that many small, individually unimpressive problems can end up adding up to one massive problem, both in terms of time and content. 4.7 The Top Flops in the SAP S/4HANA Project 121 4.7.2 Phase 1: Discover Although the project starts with a well-considered idea, the actual scope is not defined or not adopted, opening the door to possible problems. You fail to get the project sponsors to commit to a marathon. Without the support over the project’s full duration, you lack the necessary support of the sponsors— especially when it comes to critical decisions. Although you defined and approved a well-prepared project idea and scope, you did not deal with the new possibilities of SAP S/4HANA (and what is not (yet) possible). The product SAP S/4HANA is continuously developed during the project period—currently one release per year. Whether it makes sense to “take” each release with you in the project needs to be well considered. 4.7.3 Phase 2: Prepare The project plans are too aggressively optimised towards a (given) target date. Planning is too superficial, milestones are not defined, and there are no critical paths. Project and process responsibilities are not clearly defined. You don’t have the right experts (with the required skills) on board. Although the right experts are involved in the project, they are busy with day-to- day business, and the project suffers as a result (“Making money is more important than spending money”). 4.7.4 Phase 3: Explore Corporate strategies are missing or not understood by the project team. Therefore, they develop their own visions or continue with obsolete processes. They do not know what possibilities the SAP S/4HANA standard offers and do not consider these in the process design. No final decision was made on the system architecture and interface scenarios. When defining integration scenarios, interfaces between data centres are defined without considering possible restrictions (e.g. data security requirements). 4.7.5 Phase 4: Realise Essential knowledge is is lost during the project. Quality assurance measures are insufficient. Tests are started although development is still ongoing. You underestimated data migration from the old systems into the new system and did not pay attention to the employees’ professional qualifications. 122 4 The SAP S/4HANA Project: How It Is You have failed to clean up the legacy data before the data migration. The project scope is not consistently monitored. Changes are not aligned with the budget and schedule (change request management): this causes delays in the project’s course compared to the original time and budget plan. The planning becomes increasingly unrealistic, and the project is delayed. Functional and integration tests are created and carried out with data specially created for the test instead of real migrated data. These tests’ seemingly positive results are deceptive—they say very little about whether the system will run reliably after the go-live with the migrated data. This kind of test is pointless—don’t bother. The data migration duration from legacy systems is underestimated or given less priority because of an existing project delay. This leads to problems with data quality at best in the final integration test (or worst case, only after go-live) and can result in high costs and project delays. Important interfaces are not sufficiently tested before going live, as there is no test environment with suppliers. Be sure to look for creative solutions to perform interface testing as best you can. 4.7.6 Phase 5: Deploy The training material does not meet the requirements of the end users. The time needed to set up the productive systems is underestimated, and the involvement of external experts from the computer centres arrives too late.There are no clear decision criteria to determine if the go-live was successful. Interfaces to production systems are tested for the first time during go-live and do not work. 4.7.7 Phase 6: Run Excessively long downtimes before going live can impair ongoing business processes. The support structure is not sufficiently established. Important knowledge is lost. The quality of implementation and data migration often only becomes apparent after a certain period of time. This delayed manifestation means that events that do not occur immediately after production, such as month-end closing, MRP runs or similar, must be checked in detail, even if all tests were successful. 4.7 The Top Flops in the SAP S/4HANA Project 123 The Underestimated Success Factor: People 5 Among the many factors that determine a project’s success, some are more important than others: the people involved in a project are among them. In this chapter, we would like to show you how to give the people involved in your project the importance they deserve. And because we know that a lack of time and the complexity of an SAP project can block your view of what is essential, we give you practical tips from our wealth of experience to help you do this. Project Team You will learn who belongs to the project team and why you would benefit from a broader understanding of the term “project team” and the importance of project management for good teamwork. Because the qualifications, personal aptitude and availability of project members are the main criteria for selecting personnel for project staffing, we dedicate a separate section to this topic. We also show which key factors lead to high performance in a project team. On one hand, it is essential to bring the right people together in the project. On the other hand, communication must also work. If the communication is not effective, even the best project manager with the most capable team will not lead the project to success. The right communication is a decisive factor for success. Project leaders often underestimate the importance of communication in their projects. Paradoxi- cally, the bigger and more complex a project is, the more undervalued communica- tion is, although it is particularly important in such projects. We, therefore, explain how you can cultivate communication as a further success factor with effective communication structures, a supportive project culture and stakeholder-oriented messages. There is hardly a major SAP project in which people from different countries and cultures do not work together. International staffing in SAP projects can be both a curse and a blessing. We consider it above all as a blessing! In the following chapters, you will learn about the pitfalls of working with and in internationally staffed SAP project teams and how to avoid them. # The Author(s), under exclusive license to Springer Nature Switzerland AG 2022 D.

These effects, in particular digitalisation of the world of work, can also be observed and felt in the project area. We explain the essential impact digitalisation has on project management and how to deal with them to benefit your project’s success. This chapter is about something close to our hearts—the people who work together in SAP projects, day after day and often for years. In an SAP project, the SAP landscape and business processes of a company are “transformed”, as are the people involved in the project. We have interviews with some people who have gained a lot of SAP project experience. It was important for us to be able to offer you the widest possible range of expertise. That is why we spoke to people who have experienced transformation projects from different perspectives, as project members, project managers or stakeholders—from developers and experienced consultants* to CIOs. We asked them the following questions on the different topics in this chapter: • Which factors or circumstances played a decisive role in your most successful or unsuccessful/failed projects? • How present were the criteria for a high-performance team in the successfully completed projects in which you were involved? • How do you rate the criteria for team performance in projects that were not completed successfully or only with a significant time or budget overrun or change of objectives? • Based on your experience, which factors represent a high or the highest burden for the project staff? • What kind of help or support would you most like to see in the project? • Which skills are important for project management concerning digitalisation? • What advice would you give for better cooperation and better results in the project? You will find “sound bites”, unedited excerpts from the answers, in this chapter. These interview excerpts are in italics. One more note, if you have difficulty putting an idea, statement or tip into a particular drawer of project management, remember that much of this book reflects the experiences of project stakeholders. The theory often cannot be put into practice without adaptation. We derived the insights and best practices from the hard lessons of failure and the successful application of theories. 5.1 Who Belongs to the Project Team? Together We Are Strong A good team is more than the sum of its members: in addition to their technical expertise and qualifications, the project team members must bring something extra to 126 5 The Underestimated Success Factor: People put their project in the fast lane. This section shows you what abilities and personal qualities the people who fill these roles must possess. Roles in an SAP Project Let us look again at the roles in the SAP project, which you got to know in Sect. 2.2.1, “What Is a Project?” • The project leadership (including project project management) • The operational project team (the task force) • The client • The business process managers • Key users from the respective specialist departments Stakeholders are all those who can impair or hinder the project through their actions but who can also support, encourage and promote it. This definition applies regardless of the roles, tasks and interests in and on the project. In our many years of project experience, we have learned, among other things, how important it is that all stakeholders, as part of the extended project team, be seen. This approach supports the project’s sustainable success: even after a successful project conclusion, the processes, structures and, if necessary, the new culture introduced in the project will last long enough to produce the desired effects. The extended project team approach can be very helpful if you do it right. If you do it the wrong way or do not recognise the stakeholders’ importance, you may experience delays and disruptions or even see your SAP project fail. Stakeholders in the SAP Project The obvious stakeholders in addition to the project team: • The executive leadership • The heads of department • The steering committee • The works council Less obvious stakeholders include the following: • External suppliers or customers • Consultants • Placement agencies • Employees in other divisions not directly involved Figure 5.1 provides an overview of the people who belong to the extended project team. 5.1 Who Belongs to the Project Team? 127 Fi g .5 .1 O ve rv ie w of th e ex te nd ed pr oj ec t te am 128 5 The Underestimated Success Factor: People Tip: Know the Stakeholders in Your Project! Create an overview as early as possible of all groups and people who might be interested in your SAP project. Makea note of what these interests are and how they relate to the project’s course and outcome. In what ways can they support your project or, on the other hand, hinder it? This assessment is the only way you can establish effective stakeholder-oriented communication. Taken from Project Life We would like to illustrate the importance of stakeholders with an anecdote. The placement agency E-Z Expert (the name is fictitious) is supposed to provide a project with professional expertise not available within the company to a sufficient extent. With this company and all other suppliers and service providers, carefully proofed contracts are made—just like all E-Z Expert customers. In addition, the person responsible, Mr. Miller, has maintained good relationships with some top placement agencies, including E-Z Expert, for a long time. During the course of a project, two experts critical to the project’s success are unexpectedly unavailable. When this happens, E-Z Expert goes to great lengths to find the necessary personnel within the shortest possible time. They also ensure good contract terms, without the surcharge usually required when the placement must happen extremely quickly. Why is this so? Every organisation comprises people who prefer to work with other people who value them and their work and treat them with respect. Mr. Miller understands well how to treat the service providers as part of his extended project team. Through open communication and binding dealings, he ensures that the projects he manages receive higher prioritisation and particularly reliable support. The project manager or project leader, who behaves like Mr. Miller, is not only pleasant and professional; they also have leadership qualities and “preferred” status with suppliers and service providers. She or he receives the best possible price for the best possible service. For Mr. Miller, this means that even experts can be conjured up (almost) out of thin air when, despite the best planning, there is a sudden bottleneck in the project. This kind of “magic” means that the project avoids costly delays. Win-Win Situation As a project leader or project officer, you will stand out from the crowd if you set the course for the appreciative treatment of every individual on the extended project team. You will see the people, who are often only on the project sidelines, as the valuable resource they are. It is a win-win situation for everyone involved. In the next section, we look at the key skills that all project team members need to bring or cultivate to contribute to the project’s success. In line with our recommen- dation in Sect. 2.2.2, “What Types of Project Management Are There?”, to opt for a 5.1 Who Belongs to the Project Team? 129 pure project organisation for large transformation projects, we emphasise the impor- tance of project leadership here. 5.2 The Importance of Project Management Leads “To whom much is given, much is required”—this saying has never been more appropriate than in the context of good project management. One of the most far-reaching decisions for the success of a project is made early on in the project’s course, but often without enough foresight: who will become the project manager? Note: Project Management as the Supporting Pillar of the Project? In transformation projects, even with agile parts, there is still project manage- ment. Although the project manager is no longer the sole focus of the project team, the role is still very important. He or she takes on a wide range of tasks and maintains an overview of the entire project. At the same time, the project lead is the link between the different groups and people in the project teams. One of the project manager’s most important tasks as project lead, is to ensure good communication at all project levels and with all project participants and stakeholders. In doing so, the project lead must always convey messages in an appropriate way for the target group. A special challenge in connection with agile methods such as Scrum is that for correspondingly large projects, instead of just one project leader, several product owners are required. They all must also meet the high demands of this role, especially in their communication skills. The project leader must have the full support of both the client or project owner and the top management. If a project manager is assigned to a project despite reservations from key stakeholders and decision-makers, they will soon face addi- tional resistance within the project. In such situations, even the most competent project manager will find himself in a “fight against windmills”. There are plenty of examples, even outside of transformation projects, which show how unfortunate the situation can be, both for those affected and for the project itself, when a project manager, take ‘or project lead’ out is appointed who is perfectly capable but controversial and who is not accepted by all decision-makers. To illustrate, we will take the United States’ former president, Barack Obama, as an example. Many projects that were very good in terms of content had little chance of success right from the start because of strong political headwind stemming from his opponents’ resistance towards him as an individual. I am president, I am not king. I can’t do these things just by myself. (U.S. President Barack Obama from a transcript of an interview with Univision Radio, LA Times, October 25, 2010) 130 5 The Underestimated Success Factor: People Project Management Skills The project manager is to a certain degree like a Swiss Army knife. Without equating a project manager to a popular multi-tool, we want to highlight what high expectations and demands are placed on project managers. In my most successful projects, the project managers always worked in a very structured way. They communicated with all stakeholders, and they knew exactly who needed which information and reports. (Quote from a project leader) Suppose you have had the pleasure of slipping into the role of a project manager in large projects or of working with a very good project manager. In that case, you know that you also need a variety of personal qualities in addition to good specialist knowledge. Digitalisation and the desire to use more agile working methods have added to the already long list. In the following list, we have set and an asterisk (*) next to the skills that are particularly important in connection with digitalisation or more agile working methods. We also explain these in more detail below. The skills of a project manager include the following: • Agile mindset* • Tolerance of ambiguity* (serenity in dealing with ambiguity and uncertainty) • Analytical capability • Adaptability* • Readiness to delegate • Assertiveness • Dynamism/commitment • Decision-making power • Creativity* • Conflict ability* • Willingness to cooperate • Willingness to learn* • Motivation • Optimism* • Organisational talent • Resilience • Entrepreneurial thinking • Readiness to take responsibility • Negotiating skills • Networked thinking (concerning all teams, areas and stakeholders) • Trust* • Goal awareness • Targeted and solution-oriented action 5.2 The Importance of Project Management Leads 131 Below you will find the previously mentioned explanation of the characteristics and skills that with the increase in digitalisation and the introduction of agile methods, will take on increased importance for project management. In a VUCA world (Volatility, Uncertainty, Complexity, and Ambiguity), it is important to have the following qualities as a project manager: • Agile mindset (way of thinking) It is important to have an agile mindset in order to promote this in the project and to contribute to an agile project culture as well as an agile corporate culture. • Tolerance of ambiguity Tolerance of ambiguity is important to be able to accept different opinions and points of view and to be able to tolerate ambiguity and contradictions in situations and actionswithout feeling uncomfortable or reacting aggressively. • Adaptability Adaptability enables you to pursue and achieve a goal despite constant change. • Readiness to delegate A willingness to delegate is a necessary characteristic, regardless of the chosen project management methodology. Today, a successful transformation project is not possible without transferring responsibility to the right experts. • Creativity If only the goal is clear, but the way is still unknown, one must be open to new, creative ideas. • Conflict capability It is important to be equipped with the necessary resources that enable conflict ability because flattening hierarchies often make conflicts visible much earlier. Conflict capability offers a great advantage in handling disputes and conflicts in the right way. • Willingness to learn The rapid pace of digitalisation requires ever-new skills, new knowledge and continuous learning. • Optimism Optimism is important because, in projects where an iterative approach prevails, temporary defeats and setbacks must be dealt with positively. Both a positive and a negative attitude have a contagious effect on the project team. • Networked thinking Another basic prerequisite is the ability to think in a networked way—in terms of all the teams, departments and stakeholders with whom we work closely and whose different needs must always be kept in mind. Networked thinking is essential in terms of the project’s technical aspects and the communication and change management aspects. Trust It is important to have a high degree of trust, especially with a mixture of classical and agile methods, because the project manager does not determine the approach. The project leader has to delegate much more and grant decision-making powers to 132 5 The Underestimated Success Factor: People other participants or at least accept that they have them. It is important to trust in the expertise and others’ ability to judge, for example, in the development team. Management Tasks of the Project Management In order to be able to master the various steering and management tasks that await him/her in a project, the project manager must also have specialist knowledge and project experience. Still, leadership and management skills are much more impor- tant. If you recognize yourself in the following descriptive list for a project lead*, you have the best prerequisites to master your SAP project with flying colours—and if you notice that you do not yet meet all the criteria, you now have the chance to build up these skills. Key leadership responsibilities of project management include the following: • They should be role models, i.e. they should set an example of the desired and expected behaviour or appearance in the project. • They should be able to communicate project goals, milestones, plan changes, project status and problems to all relevant project participants. At this point, the information on the current status of the project, as just described, should be independently accessible to all project members at all times to enable more agile work. • They should accompany the selection interviews for key positions in the project team. • They should be able to conduct employee interviews and provide coaching for employees. • They should encourage team building and all team members’ involvement, taking into account individual and professional needs and skills. • They should manage and resolve conflicts. Tip: Solving Conflicts Constructively If you understand how and why conflicts arise, you can better manage and resolve them. A simple and effective way to deal with conflicts (not only in a project) is the so-called nonviolent communication of Dr. Marshall Rosenberg. The main principles of nonviolent communication are as follows: • Identify your observations, feelings and needs, and learn to express them without blame. • Learn to recognise and accept the observations, feelings and needs of your counterpart without criticising them. A detailed description of these methods of conversation can be found in Nonviolent Communication; A Language of Life by Marshall Rosenberg (3rd Edition 2015). 5.2 The Importance of Project Management Leads 133 Organisational Tasks of the Project Management The project processes and tasks with which the project specifications can be adhered to are planned, monitored and controlled by the project management and the specialist project managers. The most important organisational tasks of the project manager include the following: • Coordination of objectives and expected results • Coordination of milestones • Scheduling and monitoring • Budget planning and monitoring • Definition and organisation of necessary resources • Distribution of tasks within the team: with an agile approach, this task is left to the development team itself • Initiation of external resource procurement • Dynamic risk analysis (before and during the project) • Convening and organising necessary meetings with the project teams and other stakeholders • Reporting • Controlling Note: The Project Management Office (PMO) In large projects, a project management office (PMO) carries out plan controlling and monitoring. The PMO and its tasks are described in detail in Sect. 3.3, “Everything Perfectly Prepared: The Ideal Conditions”, and in Sect. 6.1, “Sup- port Whenever You Need It: The Project Management Office”. The PMO is a very important support and information source for project management. They must be able to rely on the PMO to monitor the project and inform them immediately of any deviations from the defined objectives, deadlines and results. First of all, we discuss which specific management and leadership skills project leadership requires. Since both management and leadership skills are essential for successful project completion, we have very consciously decided at this point to consider these two areas separately. We start with management skills. Leadership Skills To get started, we would like you to express your opinion. Take a pencil in your hand, think for a moment, identify five skills that you feel are essential for successful leadership in a project, and write them in the boxes below. 1. Xx 2. Xx 3. Xx 4. Xx 5. Xx 134 5 The Underestimated Success Factor: People You see, you have taken on this small task and taken a stand. Openness and decisiveness (not stubbornness) are some of the qualities that are extremely helpful for successful project leadership. From our viewpoint, the five most important leadership skills for project man- agement are as follows: • Communication skills* • Social competence* • Operational management skills (e.g. delegating work and employee coaching*) • Knowledge of methods • Professional competence Communication Skills The complex leadership role of project leadership requires very strong communica- tion skills. These enable project leaders to communicate tasks, goals and milestones effectively. They help to express praise and recognition in a targeted and effective manner. Only a few project managers who have excellent communication skills can conduct even difficult discussions in an open, direct and goal-oriented way. Effective communication is so important for a project’s success that we will go into more detail later in this chapter. Social Competence Authenticity, sovereignty and emotional intelligence (including, and in particular, empathy and influence) as an expression of social competence are also essential for the project leader to understand, motivate and bring the project team together. This team often consists of several individuals, smaller teams and other groups. The ever- increasing possibilities of digitalised and global working mean that the participants often come from diverse cultures worldwide. The team comprises experts, both from the same and different professional backgrounds with various tasks, knowledge and expectations, between whom it is necessary to mediate. The team also consists of the stakeholders alreadymentioned, some of whom have very different expectations. The project management must meet these groups of people at eye level to inform and convince them. Note: The Importance of Soft Skills The common values, interpersonal skills, knowledge and organisational cul- ture are called soft factors. Do you believe that it is worth investing time, energy and money in the so-called soft factors in your SAP project? If not, you are not alone: many project managers and the management are often not convinced of the benefits of such investments. This doubt is unfortunate, and it can be costly. It is often the neglect of the soft factors that causes a belly- landing in the project—anything but soft! And the money that a project plans to save on the soft factors is usually spent on damage control in the end, making the inglorious belly-landing even more painful. 5.2 The Importance of Project Management Leads 135 Operational Management Capability Operational management skills often play a role in large projects. They include the monitoring and controlling parts of the operational project management tasks, e.g. cost estimates or the assignment of work packages, which the project leader further delegates. The project leader must have an eye and a feeling for which tasks they can delegate and to what extent. Because even if important tasks are delegated and others must and should do them, the main project leader remains responsible for the results. Methodological Competence Methodological competence describes systemic, proven knowledge that enables a person or organisation to obtain, structure, process, correctly interpret and repeatedly apply and present information in different forms using suitable tools, techniques and methods. Examples of methodological competence include the ability to find or identify the right solutions even when faced with a multitude of possibilities, moderate discussions in a goal and result-oriented manner, resolve conflicts or ensure quality management across project interfaces. Methodological competence offers structure and, at the same time, flexibility in problem-solving and is enor- mously important for project management to achieve good results reliably—despite the momentum inherent in every project. Professional Competence Professional competence falls under management competence and leadership com- petence; however, different facets are in the foreground in each case. Professional competence is the sum of the knowledge and skills needed to complete a project on time and within budget. Professional competence is also necessary to ensure that the project’s technical and professional aspects are sufficiently taken into account to bring about a successful conclusion with the desired results. Technical expertise includes knowledge of the technology that the project team will encounter and the tools and methods required to implement it. Also, understanding of interdependencies between the technologies and their applications and limitations is necessary. Finally, you need to know what expertise is required for the introduction and successful use of the technology, even if you cannot demonstrate this expertise yourself. As a project manager, you do not have to be the top expert yourself, but you must have sufficient expertise to bring the necessary experts on board, discuss the issues with them objectively and lead them. For example, a project leader who has project management as technical expertise but has little or no understanding of the system and technology he/she is introducing will find it difficult to discuss problems and possible solutions with their teams. They run the risk that project stakeholders, especially their technical team, will call their overall competence into question. Thus, professional competence is a component of leadership competence. 136 5 The Underestimated Success Factor: People Note: Pitfall Professional Competence Many companies inevitably link career development to taking on personnel management tasks. In these cases, employees are promoted to leadership roles due to their excellent professional skills—e.g. project management. However, precisely because they have the best specialist skill, these project managers often find it difficult to break away from their previous exclusive role as “the technical expert” and delegate tasks. They jump in uninvited when technical work is being done, narrow their team’s competencies and lose sight of their broader function and additional work as a manager and leader. There is a risk that they will become overworked and demotivate the team due to their lack of confidence in their team. Furthermore, the project leader’s behaviour usually causes the project members to take increasingly less responsibility for their work and the project results. Operational vs. Strategic Management There is a basic distinction between operational and strategic management, and this difference also applies to project management. The operative management is respon- sible for all questions, problems and tasks in the project. (This is often referred to as classical or executive project management.) Operative project management asks the key question: “Are we doing the project right?” On the other hand, strategic project management addresses the question “Are we doing the right project?” and clarifies why a project investment is necessary at all. Figure 5.2 shows the relationship between strategic and operational project management and the positioning of the project leader. Strategic project management combines the strategic corporate goals with opera- tional project management, enabling the leadership to translate the strategic goals into operational project goals more easily. Through the specifications and defined goals of a project aligned with the strategic corporate goals, projects can be carried out more efficiently, bring the company more sustainable advantages and achieve a better ROI. After all, a successful project that misses the corporate goals or—worse still—undermines them is a bad investment. In the sense of a successful SAP project, the project manager is an important interface between operational and strategic project management. A good project manager must also demonstrate additional management skills, including technical and analytical skills. These skills enable them to take responsi- bility for leadership tasks and further management tasks relating to planning, organisation, personnel deployment, personnel development and controlling within the SAP project. 5.2 The Importance of Project Management Leads 137 Fi g .5 .2 S tr at eg ic an d op er at io na l pr oj ec t m an ag em en t 138 5 The Underestimated Success Factor: People 5.3 Qualification, Personal Suitability and Availability of Project Members The next important step after a project leader has been selected is planning capacities, i.e. assigning resources and resource availability planning. In the follow- ing sections, you will learn how to best proceed with your resource planning. 5.3.1 Skill Requirements in Digital Project Management Qualified Employees Among the Top 5 Success Factors The CHAOS Report 2015, published by the Standish Group in October 2015, examined a total of 50,000 IT projects of various sizes around the world over the period from 2011 to 2015. From this survey, Standish identified ten criteria crucial for project success. The factor “qualified employees” is among the top 5. Table 5.1 illustrates each factor’s importance and the Standish Group’s recommen- dation on the effort and investment that one should consider for improving a project’s success. Qualified employees are people who have the necessary professional and per- sonal skills to participate effectively and goal-oriented in the project. These people understand both technology and business. They are competent in carrying out the project requirements and delivering the project or product. So far, so good! What skills does increasing digital project managementrequire from employees? What is certain is that the number of tools and technical resources available to make projects more effective and efficient will grow, and project staff will need to be trained in these resources in real time. The areas that will initially require new digital project management skills include project organisation, information gathering and analysis and project documentation. Table 5.1 Success factors 2015, from the CHAOS Report 2015 (# Standish Group) Success factors Points Investment % Executive sponsorship (advocacy and political backing for a project by the senior management of the organisation) 15 15 Emotional maturity 15 15 User participation 15 15 Optimisation 15 15 Qualified employees 10 10 Standard architecture 8 8 Agile process 7 7 Moderate design 6 6 Project management expertise 5 5 Clear business objectives 4 4 5.3 Qualification, Personal Suitability and Availability of Project Members 139 The possibility of automating many things, increasingly informal communication channels and, in some cases, ever shorter timeframes for planning and control in projects means that new skills will also be required. From today’s perspective, we are unable to identify these skills with 100% accuracy. In our view, this is okay because the skills necessary in the future are not in the technical realm. If you need programmers or database and network administrators, you can find these workers freely on the market or “borrow” them from temporary employment agencies. What becomes much more difficult is finding the people you can fully integrate into the team who meet all the requirements of increasingly agile transfor- mation projects. They must be technically fit and have the skills to work closely with others from the business side, listen to them properly and understand their business processes. Finding these project staff is a major challenge, which is constantly changing in step with technology. This challenge is one reason that researchers are publishing one study after the other. In the following paragraphs, we describe in more detail the skills that are becoming increasingly important for project management, both now and in the future. Customer Focus The ability to work highly customer-focused is not a requirement that has arisen from digitalisation. However, it has become more important because of the greater transparency and customer intelligence (CI) (businesses now know so much about their customers) made possible by big data. These factors, in turn, drive the expecta- tion that companies meet customer needs both accurately and immediately. Change Management Transformation projects are about nothing more than change. Despite thousands of years of evolution and the new pressure to become more agile, we humans are still rarely enthusiastic about massive change. Digitalisation makes it possible to intro- duce massive change rapidly—and to do so by an entire organisation, even across all borders. Project staff at all levels must be able to see the impact of these changes. They must recognise when they need to be more empathic. For example, when employees are required to work on a transformation project that will ultimately eliminate their jobs, recognising and dealing with resistance will be crucial to the project’s progress. Understanding difficult issues or even grief reactions to change processes in an organisation is neither common nor typical in project management. However, they may still be decisive for the success or failure of the project. Dealing with Data Science The ability to work with and understand large data volumes is what enables a project leader to make the best decisions. Effective project management requires people with the ability to analyse data in the project. Innovation Mindset Project teams are increasingly encouraged to look at problems and challenges from new perspectives and find innovative solutions creatively. They need to adapt to new 140 5 The Underestimated Success Factor: People technologies, acquire new knowledge and skills and discover and take advantage of the latest opportunities. In this context, it is important to have the ability to distance oneself somewhat from what was and what is to discover solutions that have never been there before. Data Security Since the DSGVO came into force in Europe in May 2018, data security and data protection are a very high priority for many project teams. Companies want to protect both their own data and the data of their respective customers (consumers). Compliance Knowledge The project management team should by no means assume the tasks of compliance experts. The team must nevertheless understand how far compliance issues can influence the implementation of their projects. Project teams must have knowledge of legal rules and regulations that affect the implementation and management of a project. These rules range from labour laws to tax regulations. It is important to have at least enough knowledge to decide when to call in compliance experts. Ability to Make Data-Based Decisions Project managers have always needed the ability to make data-driven decisions. Now, with digitalisation comes a flood of data that is brought together and transformed into applicable information. Therefore, the ability to use data as a basis for decisions that drive the project has gained importance. Collaborative Leadership Skills The requirement for collaborative leadership qualities is also not a direct result of digitalisation because collaboration in cross-function teams has always been impor- tant for project management. Projects are becoming more complex and hierarchies flatter, so the ability to influence other people is becoming even more important. Only those with collaborative leadership skills can bring together teams with different needs and individual goals to achieve great common goals. 5.3.2 How to Select the Right Employees Building a Strong Team In this section, by resource selection, we mean the selection of personnel for the project team. It is important to find the people who have the necessary skills to plan, carry out and complete their tasks in the project. It’s all very simple: if you look at both quality and quantity when selecting personnel, you’ve won—you just need to know which people with which qualifications you need in the project and how many. In reality, of course, it’s simple, yet not that easy. For your project, you are looking for suitable people both professionally and personally for a large, important, possibly long and often stressful undertaking. 5.3 Qualification, Personal Suitability and Availability of Project Members 141 Your project staff must be able to work independently. For this, they need profes- sional expertise. To determine what specific expertise your project members need, get an overview of the project’s different requirements. Then decide what skills you need onboard. Don’t just look at who is “there and available”. Role Descriptions The creation of role descriptions and a catalogue of questions to select resources is a great help when selecting employees. First, create a role description for the different positions you want to fill. For each role, develop a list of questions to determine the criteria for a suitable resource. The role description documents the role with the associated tasks and processes that are to be performed by one or more employees. We recommend that you create role descriptions for roles relating to SAP processes and all other project roles. Catalogue of Questions The catalogue of questions includes a collection of questions that will help you identify the appropriate resources for the project. The following questions belong in the employee selection process for each SAP project: • What technical qualifications are required? • What is the required professional expertise? • Which soft skills does the employee need (in particular)? • How often do I need this employee (in terms of weekdays)? • How importantis project experience for this position? • Over what timeframe should the employee work on the project? • In which other project is the employee already involved or planned? • In which area is the employee already involved in day-to-day business? • On how many days of the week is the employee working on other projects or with other tasks? We deliberately calculated with weekdays instead of percentages in the questions on the deployment of the employee. This approach allows you to identify potential conflicts in the later availability of resources more quickly. Taken from Project Life Here is an example: if the head of the HR department promises you that Mr. Schroeder from his department will be allowed to work 40% of his 40-hour week on a project with you for a month, you will initially be pleased. You can now expect to integrate Mr. Schroeder into the project for 16 hours a week without any problems because 40% of 40 hours is 16 hours. However, the calculation does not add up. The joy will quickly evaporate as soon as you realise that Mr. Schroeder is only theoretically available because he is completely indispensable to his department 3 days a week. Unfortunately, you need Mr. Schroeder for at least 3 hours on 5 days of the week for functional tests during the planned hot phase. You only have 2 days on which Mr. Schroeder is actually available. 142 5 The Underestimated Success Factor: People If you had planned to have Mr. Schroeder and an SAP expert work in a daily test and review cycle, you would now have to organise the work packages differently. This example should clearly illustrate what effects exact availability can have on work planning. It should also clarify why you should think and communicate both in terms of the percentage of working time and the weekdays when coordinating the project staff. Methods in Personnel Selection There are different methods to support the selection of personnel for external or not yet existing project members. Some of the possibilities to provide a basis for decision making are as follows: • Review and analysis of the application file • Interviews • Technical tests • Assessment centre • External personnel agencies (with a focus on IT projects) We recommend that for each important position or role in the project, the personnel selection process should include a personal interview and at least one other selection method. The different selection methods provide additional informa- tion about a potential employee and look at the person from different perspectives. If, for example, you are looking for a specialist in the team, it is useful to check the candidate utilising specialist tests. Specialised testing is particularly important if a candidate cannot sufficiently prove the desired expertise through documented and verifiable experience. The Chemistry Is Right! However, you should not rely exclusively on quantitative assessment methods, such as performance tests when selecting personnel. These methods disregard some important factors, such as personal disposition (including motivation, punctuality and teamwork) or the proverbial “chemistry”, i.e. interpersonal harmony or possibly disharmony. Interpersonal harmony is a factor that strongly influences cooperation, in both a positive and negative sense. Since a large project almost always involves a high workload under increased time pressure, it is particularly important to rule out any avoidable disruptive factor from the outset. The latter is another reason why it is best to establish the personal interview as an integral part of personnel selection for important positions. Filling the project team with staff already in the organisation must be carried out with similar criticality to selecting personnel from candidates via external sources. Take a close look at the staff for key projects. Make sure that they have the expertise and experience required for the position or role in question. 5.3 Qualification, Personal Suitability and Availability of Project Members 143 What Doesn’t Fit Is Made to Fit! When selecting project members from existing staff within an organisation, the project leader may (have to) follow the motto “if it doesn’t fit, make it fit”. This saying is not a reference to a special training program or a meaningful qualification measure for the project staff. Sometimes management expects or even demands the project leader utilise the available staff and make the best of it. If you find yourself in this position and the technical expert, who has practically been forced onto your project, has frightened away everyone with whom he has ever worked, you must be proactive. The best thing to do is make your teamwork expectations clear early in the project and facilitate team player skills through targeted coaching. Ideally, the coaching should happen before the project begins. If the person does not accept the coaching, or the coaching is not effective, and you cannot replace the individual, give them a wide berth and minimise their interactions with the team. Do your best to avoid taking on such team members by stressing the importance of team fit and culture during the very early project planning phases. 5.3.3 To Ensure the Availability of Resources In our context, resource availability refers to the actual availability and accessibility of the resources planned in the project. When it comes to resource availability, your first priority is to ensure that the people you schedule in the project are actually available when you plan them. It sounds like a straightforward matter, yet this simple requirement can often be extremely difficult to implement in reality. Why is that? This section answers that question. We will look at the aspects of resource security that require particular attention and the factors that often make it difficult to ensure the availability of resources. Ensure Specific Technical Knowledge The specialist technical knowledge needed in your project depends on several factors, including the project objective and the industry in which your client operates. Taken from Project Life An SAP project at a large shipping company is an example of a requirement of special technical knowledge. In this example, the management of incoming goods, processes, warehouse and operations management and the administration of outgo- ing goods processes are to be optimised. The project is to optimise by implementing the SAP Extended Warehouse Management (SAP EWM) solution, which under SAP S/4HANA is now part of the core and no longer an additional component. In this example, it is important to have resources (people) with the expertise on this SAP solution for logistics and order fulfillment in the project team. 144 5 The Underestimated Success Factor: People Take Important Employees into Account in the Planning It happens more often than you might think that a project involves employees who can only work in theory or even exist only in theory. Identify Knowledge and Trust Carriers Over the years, we have repeatedly encountered situations similar to the following: the employee, Ms. Meyer, is most familiar with the finance department’s business processes. She is also the only colleague who is widely accepted and respected by everyone in the department. Ms. Meyer is finally able to fulfill her dream of a 6-week trip to Australia. Unfortunately, her absence is during the process analysis phase of the project, so the project team conducts an important basis of the project without participation from the expert and highly trusted person, Ms. Meyer. The result is that the department and department management colleagues mistrust and have little confidence in the project from the very beginning. This mistrust creates a success-critical hurdle for the project. The example above illustrates that it is extremely important to identify the required technical and business experts early to secure their participation in critical project activities. The same applies to employees who can positively
