Unit 4: Evolutionary Process Models

5. The goal of prototyping based development is to counter the first two limitations of the Notes
waterfall model. Discuss.
6. Development of the prototype obviously undergoes design, coding and testing. Justify
your answers with examples.
7. The client can get an “actual feel” of the system, since the interactions with prototype can
enable the client to better understand the requirements of the desired system. Discuss.
8. As it is clear from the name, the activities in this model can be organized like a spiral that
has many cycles. Explain.

9. The radial dimension represents the cumulative cost. Substantiate with suitable examples.
10. Why concurrent development model, sometimes called concurrent engineering?
