Explain the prototyping approaches in software process.
Two approaches
i. Evolutionary prototyping - In this approach of system development, the initial prototype is prepared and it is then refined by number of stages to final stage.
ii. Throw-away prototyping - Using this approach a rough practical executionof the system is produced. The requirement problems can be identified from this execution. It is then discarded. System is then developed using some disimilar engineering paradigm.
