Understanding Agile Software Development Life Cycle (SDLC)

In today’s fast-paced and dynamic business environment, organizations need to adapt quickly to changing requirements and deliver software products that meet customer expectations. This is where Agile Software Development Life Cycle (SDLC) comes into play

I cannot give you the formula for success, but I can give you the
formula for failure. It is: Try to please everybody.
– Herbert Bayard Swope

What is Agile SDLC?

Agile SDLC is an iterative and incremental approach to software development that focuses on collaboration, flexibility, and customer satisfaction. It provides a framework for project management and product delivery, emphasizing the need for continuous feedback and adaptation throughout the development process.

Key Principles of Agile SDLC

  1. Customer Collaboration over Contract Negotiation: Agile SDLC recognizes the importance of involving customers throughout the development process to ensure that their requirements are accurately captured and incorporated into the software product.
  2. Embracing Change: Rather than resisting change, Agile SDLC embraces it as a natural and necessary part of software development. It encourages the development team to be flexible and adaptable in response to changing requirements.
  3. Iterative and Incremental Development: Agile SDLC breaks down the development process into small iterations, known as sprints, where a working product increment is delivered at the end of each iteration. This iterative approach allows for early customer feedback and reduces the risk of developing a product that does not meet expectations.
  4. Self-Organizing and Cross-Functional Teams: Agile SDLC encourages self-organizing teams, where members collaborate closely and share responsibilities. This promotes effective communication, knowledge sharing, and faster decision-making

Phases of Agile SDLC

  1. Requirement Gathering: The project team works closely with customers and stakeholders to identify and prioritize the requirements. User stories are created to capture the specific needs and expectations of the customer.
  2. Planning: The development team, along with the customer, determines the scope and time frame for each iteration. The project backlog is created, comprising user stories to be addressed in the upcoming sprints.
  3. Design and Development: The development team starts building the software based on the requirements. Regular meetings and demonstrations with the customer provide opportunities for feedback and validation.
  4. Testing and Quality Assurance: Testing is an integral part of Agile SDLC, with automated testing tools being widely used. Regular testing helps identify and fix issues early in the development process.
  5. Deployment and Delivery: At the end of each sprint, a shippable product increment is delivered to the customer. This allows for early feedback and ensures that the customer is continuously involved in the development process.
  6. Feedback and Adaptation: Agile SDLC encourages continuous feedback from customers and stakeholders. This feedback is used to adapt and refine the product, incorporating changes and enhancements in subsequent sprints.

Benefits of Agile SDLC

  • Faster time-to-market: The iterative nature of Agile SDLC allows for regular product deliveries, reducing time from development to deployment.
  • Increased customer satisfaction: Continuous involvement of customers promotes collaboration, resulting in a product that meets their expectations.
  • Early detection of issues: Regular testing and feedback help identify and address issues at an early stage, reducing the risk of major setbacks.
  • Flexibility and adaptability: Agile SDLC allows for changes to be incorporated throughout the development process, ensuring that the final product is aligned with evolving requirements.


Agile SDLC provides a flexible and customer-centric approach to software development, enabling organizations to respond quickly to changing market needs. By embracing change, fostering collaboration, and delivering incremental product increments, Agile SDLC helps organizations achieve faster time-to-market and customer satisfaction.
