Question

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

Answer 1

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.

Answer 2

The spiral model can be obliged in prototyping and waterfall show. it is a model of an iterative procedure as prototyping and furthermore, an efficient way to deal with taking care of an issue as in waterfall display.

The spiral model takes the issue as a progression of advance to take care of an issue as in waterfall and take the commitment of clients or clients in each stage as in prototyping model.

The Prototyping Model is a frameworks improvement technique (SDM) in which a model (an early estimation of a last framework or item) is assembled, tried, and after that modified as important until the point that an adequate model is at long last accomplished from which the entire framework or item would now be able to be created.
