WATERFALL MODEL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The ____ approach is an SDLC approach that assumes the output of each phase is finished before moving on to the next phase.​
A
Iterative
B
Spiral model
C
Waterfall model
D
Prototyping
Explanation: 

Detailed explanation-1: -The modified waterfall approach requires overlapping phases. True. The predictive waterfall SDLC explicitly includes a support phase, but the adaptive SDLCs do not.

Detailed explanation-2: -The SDLC that is the most predictive is called the waterfall model, an SDLC that assumes the various phases of a project can be completed sequentially-one phase falls into the next phase, and there is no going back as shown in Figure 10-3. This approach is almost never used any more.

Detailed explanation-3: -The waterfall model is a linear, sequential approach to the software development lifecycle (SDLC) that is popular in software engineering and product development. The waterfall model uses a logical progression of SDLC steps for a project, similar to the direction water flows over the edge of a cliff.
