Detailed explanation-1: -Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion.
Detailed explanation-2: -Traditional SDLC. With the traditional methodology, each phase is an independent, isolated activity. One phase has to be completed before the next phase begins. This methodology is termed waterfall, because phases “trickle down” into one another until the application is developed.
Detailed explanation-3: -The Waterfall methodology-also known as the Waterfall model-is a sequential development process that flows like a waterfall through all phases of a project (analysis, design, development, and testing, for example), with each phase completely wrapping up before the next phase begins.
Detailed explanation-4: -Waterfall Model: No working software is produced until late during the life cycle. We can not go back to the previous project phase as soon as we proceed to the next phase, So inflexible. Hence the correct answer is the Waterfall model.
