Best Answer

Waterfall model uses sequential design process, in which each phase is tested in level by level like a waterflow from top to bottom. In waterfall model once we come out of the phase, there is no possibility to change something according to the new requirement, once the phase is done then it is just done. Waterfall model is applicable for small projects.

because it does not allow you to go back to a previous step or skip a step

In waterfall model we have 5 stages, that gives a software product at the end. In prototyping model, a prototype is made instead to refine the requirements more properly.

Waterfall model and prototyping model can be accommodated in spiral model?

1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.
