Waterfall Model

The Waterfall Model is a sequential software development methodology, progressing through distinct phases like requirements, design, implementation, testing, and deployment. It follows a linear structure where each phase must be completed before moving to the next, making it suitable for projects with well-defined and stable requirements. However, its rigidity poses challenges in accommodating changes during the development process. Despite its limitations, the Waterfall Model is still employed in scenarios where requirements are known and unlikely to undergo significant alterations.
