Waterfall Model
The Waterfall Model is a linear and sequential approach to software development, characterized by its phases flowing steadily downwards like a waterfall, hence the name. In this model, each phase must be completed before the next one can begin, ensuring a clear delineation between them. The stages typically include requirements gathering, system design, implementation, testing, deployment, and maintenance. This methodology emphasizes thorough documentation and rigorous testing to minimize errors and ensure high-quality software. It is well-suited for projects with clearly defined requirements and minimal scope changes, making it a popular choice in traditional software development.
