What is the traditional iterative model of software development that includes stages like Analysis, Design, and Testing?

The traditional iterative model of software development characterized by structured stages such as Analysis, Design, and Testing is the Waterfall model. This model is linear and sequential, emphasizing a clear progression through distinct stages. Each stage must be completed before moving on to the next, which allows for fine-tuned planning and documentation at each step.

In the Waterfall model, the process typically begins with requirements gathering and analysis to understand what the software needs to achieve. This is followed by a design phase, where system architecture and interfaces are created. After that, the implementation phase occurs, where the software is actually developed. Once the coding is completed, testing is conducted to ensure that the software meets the specified requirements and functions correctly.

This model's predictability and structured nature make it well-suited for projects where requirements are well understood and unlikely to change during the development process. The emphasis on documentation and phased completion also aids in maintaining clarity and control over the project's progress.

Other models, like Agile, focus on flexibility and iterative development through continuous feedback and adapting to change, which differs significantly from the more rigid structure of the Waterfall model. The Spiral model combines elements of both iterative and waterfall strategies but emphasizes risk assessment at each iteration. The V-Model, while
