Iterative Software Development Life Cycle

Back to: SDLC Methodology Tutorial

The Iterative Software Development Life Cycle (SDLC) is an approach to software development that involves breaking down the project into smaller, more manageable parts and developing them in iterations or cycles. Each cycle is a self-contained mini-project, consisting of planning, requirements gathering, design, development, testing, and deployment.

The iterative SDLC involves the following stages:

  1. Planning: In the planning stage, the team identifies the project goals, requirements, and scope, and creates a roadmap for the development process.
  2. Requirements Gathering: In the requirements gathering stage, the team identifies the user requirements and expectations, and defines the features and functionality of the software.
  3. Design: In the design stage, the team creates the high-level architecture of the system, including wireframes and prototypes.
  4. Development: In the development stage, the team develops the software in iterations, typically ranging from two to four weeks. Each iteration includes coding, testing, and integration of the features.
  5. Testing: In the testing stage, the software is tested rigorously to ensure that it meets the requirements and is free of defects.
  6. Deployment: In the deployment stage, the software is deployed to a production environment, and the team monitors its performance and user feedback.
  7. Feedback and Iteration: In the feedback and iteration stage, the team collects feedback from users and stakeholders and uses it to improve the software. The team can then start another cycle or iteration of the SDLC to implement these changes.

The iterative approach allows teams to deliver working software quickly and efficiently, while also providing opportunities for continuous improvement and feedback. Each iteration builds upon the previous one, enabling teams to refine and improve the software gradually. This approach is particularly useful for large and complex projects, where it can be challenging to identify all the requirements upfront. The iterative SDLC allows teams to adapt to changing requirements and deliver high-quality software on time and within budget.
