The Launching Phase of an Iterative SDPM Strategy for the Evolutionary Development Waterfall Model

The Launching Phase of an Iterative SDPM strategy for the Evolutionary Waterfall model has all four of the considerations stated in the previous section for the generic Iterative situation. Figure 20-2 highlights the Launching Phase of an Iterative SDPM strategy for the Evolutionary Development Waterfall model.

Keep in mind that the Evolutionary Development Waterfall model embraces a wide range of situations depending on the extent to which the solution is complete. The more features that are missing from the solution, the more time you will need to allocate to the customer as they work with deliverables from previous iterations. The number and frequency of scope change requests is a function of the degree to which the solution is incomplete. Initially you might expect a higher frequency of scope change requests. As you near the final and complete solution, the number and frequency of scope change requests should begin to diminish. If that is not the pattern, you have a serious problem to contend with—the solution is diverging instead of converging to completeness. The customer should sense this before you do, but it does require some corrective action. Remember, the customer ...
