Iterative Methodology
Iterative methodology is a software development approach that emphasizes incremental and repetitive progress. It involves breaking down a project into smaller cycles or iterations, each of which results in a functional part of the software. After each iteration, stakeholders can review the work and provide feedback, which is then used to refine and enhance subsequent iterations.

Key principles
- Incremental Development: The project is divided into small, manageable parts or iterations. Each iteration adds new functionality or refines existing features;
- Feedback and Review: Stakeholders, including users, product owners, and developers, regularly review the work completed in each iteration. Feedback guides further development;
- Flexibility: Iterative methodologies are adaptable to changing requirements, allowing adjustments to be made at the end of each iteration based on feedback and evolving project needs;
- Continuous Improvement: The goal is to refine and enhance the software with each iteration, making it more functional, reliable, and user-friendly over time.
Iterative vs Waterfall
Aspect | Iterative Model | Waterfall Model |
---|---|---|
Development Approach | Incremental and repetitive, with frequent cycles of planning, designing, building, and testing. | Sequential, with distinct phases (requirements, design, implementation, testing, deployment) performed in order. |
Flexibility | High flexibility, allows for changes and adaptations at the end of each iteration. | Low flexibility, changes are difficult and expensive to implement once a phase is completed. |
Stakeholder Involvement | Frequent stakeholder engagement through iterative reviews and feedback. | Limited stakeholder involvement until the end of the project. |
Delivery Time | Deliveries are incremental, allowing users to benefit from partial functionality early in the project. | Final product is delivered after all phases are complete, resulting in a longer delivery time. |
Quality Assurance | Frequent testing and refinement lead to potentially higher software quality. | Rigorous testing is performed after development, potentially leading to lower quality if issues are discovered late. |
Adaptability | Well-suited for projects with evolving or unclear requirements. | Best for projects with well-defined and stable requirements. |
