PURPOSE

The core engineering workflows presented in sequence from Chapter 8 through Chapter 15 may wrongly give an impression of a waterfall process. Remember that they are archetypal workflows designed to give an overview of all activities; the activities in the workflows are revisited again and again at each iteration. The actual work performed on a project varies depending on the nature of the project and where you are in the lifecycle.

In Chapter 3 we introduced the concept of the typical iteration plan, which describes the work that is performed as the project goes through one iteration. In this chapter, we give three examples of typical iteration plans:

An iteration in the inception phase to define the project vision and the business case
An iteration early in the elaboration phase to build an architectural prototype
An iteration late in the construction phase to implement the system

These examples are skeletal and do not involve all activities from all workflows.
