Differentiation between iterative model and waterfall model

Question

Write down differentiation between iterative model and waterfall model.

Answer 1

Waterfall Model : This is a flow which is only based on model, in that we pass every phase once, and can’t go back to that phase again.

Drawback : If there is any transform in requirements, then we can’t create any changes in the requirements. Iterative Model: In this we can come reverse to preceding phases, and create the changes accordingly. In this we revived final output product at the end of SDLC.
