Different Phases of Iterative Incremental Model

The following are the typical phases in the Iterative Incremental Model:

1. Planning Phase

In this phase, the team identifies the goals and objectives of the project, along with the project scope, requirements, and constraints on them. The team then identifies different iterations that would be needed to complete the project successfully.

2. Requirements Analysis and Design Phase

In this phase, the requirements met are then analyzed and the according system is designed based on these requirements. The projected design should be modular, which would allow easy modification and testing in subsequent iterations.

3. Implementation Phase

In this phase, the system is implemented based on the design created in the previous phase. The implementation should be done in small, manageable pieces or increments, which can then be tested in the next phase of the cycle.

4. Testing Phase

In this phase, the system is tested against the requirements identified in the planning phase. Testing is done for each iteration, and any defects or issues are identified and resolved, and this helps in each iteration.

5. Evaluation Phase

In this phase, the team evaluates the performance of the system based on the results of testing. Feedback is gathered from users and stakeholders, and changes are made to the system as needed which makes the system more scalable and flexible.

6. Incremental Release

In this phase, the completed iterations are released to users and stakeholders. Each release builds on the previous release, providing new functionality or improving existing functionality to a great extent.

The Iterative Incremental Model is a smart way to design complex systems. Instead of trying to figure everything out at the beginning, this approach breaks the project into smaller parts. Each part is then developed, tested, and added to the system, bit by bit. This method is great for projects where things might change or if the requirements aren’t clear from the start. It allows designers to focus on making each part work well before adding more, leading to a better overall system.
