Waterfall Model
The Waterfall Model is a linear, sequential software development methodology where each phase (e.g., requirements, design, implementation, testing, deployment) must be completed before the next begins, with minimal overlap or iteration. It emphasizes thorough documentation and upfront planning, making it suitable for projects with well-defined, stable requirements. This approach contrasts with more flexible, iterative methodologies like Agile.
Developers should learn the Waterfall Model to understand traditional project management and its application in industries with strict regulatory or compliance needs, such as aerospace, defense, or medical devices, where changes are costly. It is useful for projects with fixed scopes and timelines, providing clear milestones and deliverables, but it is less adaptable to evolving requirements compared to Agile methods.
