Agile SDLC (Software Development Life Cycle)
Last Updated : 23 Jul, 2025
Software Development Life Cycle (SDLC) is a process of maintaining or building software
applications/services/systems. Generally, it includes various levels, from initial development plan and
analysis to post-development software testing and evaluation. It also consists of the models and
methodologies that development teams use to develop the software systems. An information system
is designed to perform a particular set of assignments. Frequently, this set of tasks that the system
will perform offers well-defined results, which include complex computation and processing.
It is a hard and boring job to govern the entire development process to ensure that the end product
comprises a high degree of integrity and strength, as well as user acceptance.  Thus, a systematic
development process that can point to the understanding of the scope and complication of the total
development process is essential to achieve the characteristics of a successful system.
Presently, two SDLC methods are used by most system developers. They are traditional development
and agile development.  In this article, we will discuss about Agile Software Development Cycle.

What is the Agile Software Development Life Cycle (Agile SDLC)?
The Agile Software Development Life Cycle (SDLC) is an iterative and incremental software
development methodology that prioritizes flexibility, collaboration, and customer feedback. Unlike
traditional SDLC models, such as the waterfall model, which completes each step sequentially, the
agile SDLC divides the development process into smaller iterations or increments.

Phases of Agile SDLC
Requirement gathering
Design the Requirements
Coding
Testing
Deployment
Feedback
1. Requirement Gathering: In requirement Gathering collaboration takes place with stakeholders to
understand and prioritize needs for the project, that focus on delivering value. In this step techniques
like user stories and workshops for effective communication.
2. Design the Requirements: In design the requirement step that gathered requirements is translated
into actionable tasks, breaking them down into smaller, manageable chunks. In this step developers
develop visual representations of the solution, such as wireframes or prototypes, to get early
feedback and ensure alignment with stakeholder expectations.
3. Coding: During the coding step, the development team implements the software in short, iterative
cycles known as sprints. Each sprint focuses on delivering small, functional increments of the product.
Developers write code, continuously integrate it into the main codebase, and regularly commit
changes to detect and address issues early.
4. Testing / Quality Assurance: Testing is an integral part of each iteration, ensuring the quality and
functionality of the software. Unit tests are written to verify individual components, while integration
tests check that different parts of the system work together as intended. User Acceptance Testing
(UAT) involves end-users testing the software in real-world scenarios to ensure it meets their needs.
5. Deployment: Deployment involves releasing the software increments to production frequently and
reliably. Automated deployment tools makes the process, allowing for quick and consistent releases.

https://www.geeksforgeeks.org/software-testing/software-testing-basics/
https://www.geeksforgeeks.org/software-engineering/software-deployment-in-software-development/
Monitoring the deployment process and system performance helps identify and resolve any issues
promptly.
6. Feedback: Feedback is crucial for continuous improvement in Agile. Stakeholders and end-users
provide feedback through surveys, direct communication, and usage analytics. This feedback is used
to refine requirements, prioritize changes, and identify areas for improvement.
Agile SDLC Process Flow
Concept: In concept phase vision of the project, its scope, objectives, and goals are set.
Inception: This stage is conducted before Construction. The major goal of this phase is to complete
just enough work to get your team moving in the correct direction.
Iteration/Construction: The main goal of this phase is to create a consumable solution with
enough functionality to satisfy your stakeholders' present needs, or to configure it in the event of a
package implementation.
Release: This stage normally involves final performance testing, security assessments, and
documentation updates, as well as user acceptability testing (UAT), which ensures that user
demands are satisfied and the product is successful. When the software is complete, it is released
into production or made available to users.
Production: The Production Phase aims to keep systems viable and productive after they have
been deployed to the user population.

Agile SDLC Models
Six methods are identified as agile development methods they are following :
Crystal methodologies
Dynamic software development method
Feature-driven development
Lean software developmentScrum
Extreme programming 
Software Development Life Cycle is a technique that shows the entire development process, which a
software development organization must use to guarantee a successful software development.  
Rules to identify the desired SDLC
There are some rules that the development crew could use to identify the desired SDLC. These
include 
1. The size of the crew
2. Geographical situation
3. Size of Software
4. Complication of software
5. Types of projects
6. Business strategies
7. Engineering capability and others where it may be found suitable.
It is also crucial for the crew to study the differences, advantages, and disadvantages of each SDLC
before rejecting the decision. An SDLC selection and adoption process are important in that it ensures
the organization maximizes its chance for delivering its software successfully.
Advantage of Agile SDLC
Following are the Advantage of Agile SDLC
Responds to Change: Agile allows for changes in requirements even late in the development
process, adapting to evolving business needs and market conditions.
Iterative Development: Features are developed in small, manageable increments, making it easier
to pivot or refine the product as necessary.
Continuous Testing: Regular testing at each iteration helps identify and fix defects early, ensuring
higher quality.
Incremental Releases: By delivering small, functional parts of the project regularly, Agile ensures
that valuable features reach users faster.
Frequent Feedback: Regular interaction with customers and stakeholders ensures that their needs
are met and their feedback is incorporated.
Cross-Functional Teams: Agile promotes collaboration among diverse team members, including
developers, testers, designers, and business analysts.
Focus on Priorities: Agile helps teams prioritize tasks that deliver the most value, reducing waste
and focusing efforts on what matters most.

Early Issue Detection: Regular iterations and continuous integration help identify and address risks
early in the development process.
Transparency: Agile methodologies like Scrum involve daily stand-ups, sprint reviews, and
retrospectives, providing clear visibility into progress and challenges.
Retrospectives: Regular reflection on processes and outcomes allows teams to identify areas for
improvement and implement changes effectively.
Disadvantage of Agile SDLC
Following are the disadvantage of Agile SDLC
Variable Scope: Frequent changes in requirements can make it hard to predict the final scope of
the project.
Uncertain Costs and Timeline: Iterative development means that the exact time and cost of
completing the project can be difficult to estimate upfront.
Minimal Documentation: Agile focuses on working software over comprehensive documentation,
which can lead to insufficient documentation.
Changing Requirements: Continuous changes can lead to scope creep, where additional features
are added without corresponding increases in time or budget.
Training Needs: Teams unfamiliar with Agile need training to understand and effectively
implement Agile practices, which can be time-consuming.
Continuous Integration Demands: Agile requires frequent integration of new code, which can be
technically challenging and require robust tools and practices.
Technical Debt: Rapid development cycles can result in the accumulation of technical debt if not
managed properly, affecting future maintainability.
Conclusion
The Agile SDLC model offers a flexible and iterative approach to software development, promoting
continuous collaboration, rapid delivery, and responsiveness to change. This model enhances
customer satisfaction through frequent deliveries and the ability to adapt quickly to evolving
requirements. Agile SDLC is well-suited for dynamic projects where requirements are expected to
change and where early and frequent delivery of product increments is crucial. Adopting Agile
requires a cultural shift, effective communication, and a commitment to iterative improvement, making
it a powerful tool for delivering high-quality software.
