Spiral Model: Spiral Model consists of 4 phases: 1)Planning
2)Risk Analysis 3)Engineering 4)Evaluation.
Prototyping is part of Spiral model and it is done in the
last stage of risk analysis. The radius of the spirals show
cost and angular brackets show progress.
Whereas in
Prototype Model: when the client is not clear with
requirment one dummy project is created presented to the
clint according to the clinet suggestions then again all
steps are applied to make it again.
