Figure 12-4 is the Planning Phase of the Incremental SDPM strategy for the Staged Delivery Waterfall model.

Figure 12-4. Planning Phase of an Incremental SDPM strategy for the Staged Delivery Waterfall model

For planning the Incremental SDPM strategy for the Staged Delivery Waterfall model, you would know all of the planning input. The RBS would have been generated during the Scoping Phase and is all of the input needed to build a complete project plan. There are six major tasks that you need to do to generate the project plan. They are:

• Building the complete WBS

• Estimating task duration

• Estimating resource requirements

• Building the precedence diagram

• Allocating functions and features to determine number of stages

• Creating the initial project schedule

Each of these tasks is briefly described in the following subsections.

Building the Complete WBS

The RBS is the only input needed here. The RBS is a deliverables-based WBS and needs only to be further decomposed to the task level. Each feature is therefore decomposed until it satisfies the completion criteria. See Appendix E for details.

Estimating Task Duration

Features are rather primitive deliverables and the clock time needed to build them should be easy to estimate. Features are likely to have been defined for other projects. If they are ...
