Question

Explain how both waterfall model and prototyping model can be accommodated in the spiral process model

Answer 1

Explanation:

The waterfall model is ideally used when the risk in the specification is low resulting in no need of risk resolution measures like prototyping. In this case, the second quadrant based activities of the spiral model are skipped. The Prototyping model is ideally used when the specification phase is less and the prototyping or risk resolution is quite high. The third quadrant based activities of the spiral model are skipped or have reduced scope.
