Unformatted text preview: similar work packages in the past. Such spread curves are often called statistical distributions or historical distribution spread curves. An example of a hypothetical historical distribution spread curve is shown in Figure 2- 20(c). Modern Project uses the linear approximation spread curve as shown in Figure 2-20(b). This is the time-phasing (spreading) method that is best for work packages that satisfy our assumptions about work packages. If one wants to spread a long duration work package via some historical distribution function, modeling the distribution function with tasks of unequal dura- Figure 2-20.

It will probably occur to the reader how to do such a thing but we will not take up space explaining it here. Figure 2-21 illustrates how the time-phased budget for a summary level control package in the WBS is obtained. First, all the budgets that roll up into this control package are added to produce the budget for the control package. Next the start and the end dates for the control package are determined by taking the earliest start date and the latest finish date of the work packages that are contained in the control package. Finally, the budget contribution of each lower-level work package during each time period (reporting period) in the summary level control package's duration between its start and end dates are summed, yielding the summary level control package distribution. 2.7— The Baseline Chart After the schedule dates have been entered into the database for the tasks, a baseline chart can be displayed that depicts the time phasing of the budget. Figure 2-22 shows the baseline chart for the example project so far. Figure 223 shows the baseline chart for the example project at a later point in time. We arrive at that point in Chapter 6, when the control budget has diverged significantly from the original budget. Figure 2-23 has been included here to emphasize that the baseline will evolve as the project progresses.

In Chapter 2, we discussed project planning and the construction of a project plan. We also explained how this planning information could be entered into a database using the Modern Project desktop toolset supplied with this book. In this chapter we discuss what information needs to be collected as the project progresses. At this point it is worthwhile reviewing where it is we have been and where we are going to see how project monitoring fits into the project management process. Recall that at the beginning of Chapter 2 we s...
