Detailed explanation-1: -In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases. The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow.
Detailed explanation-2: -The five-stage waterfall model, which is based on the requirements of Winston W. Royce, divides development processes into the following project phases: analysis, design, implementation, testing, and operation.
Detailed explanation-3: -In “The Waterfall” approach, the whole process of software development is divided into separate phases. The outcome of one phase acts as the input for the next phase sequentially. This means that any phase in the development process begins only if the previous phase is complete.
Detailed explanation-4: -Requirements phase This is the initial planning process in which the team gathers as much information as possible to ensure a successful project. Because tasks in the waterfall method are dependent on previous steps, it requires a lot of forethought.
