Project plan

It sounds so simple, doesn't it? Then why is this so tough? Well, we will cover this in more detail later in this chapter, but these two basic prerequisites are where most estimating woes originate. There is often not a clear or complete understanding of the work to be performed by the person doing the estimate, and the relationship between the work estimate and the resource doing the work is not defined or communicated. In addition, there is the challenge of estimating work that has not been done before in exactly these conditions.

Accurate estimates build the foundation for a realistic schedule and an accurate project budget.

Yet, estimating the work effort is a cornerstone activity for planning the project. From these work estimates, we determine the project costs (see Chapter 9, "Determining the Project Budget"), develop the project schedule (Chapter 8, "Developing the Project Schedule"), and identify key project risks. This relationship is illustrated in Figure 7.2.

Figure 7.2. Shows the foundational role that the WBS and the work estimates play in the overall planning process.
