Scheduling resources

Having produced the resource requirements list, the next stage is to map this onto the activity plan to assess the distribution of resources required over the duration of the project. This is best done by representing the activity plan as a bar chart and using this to produce a resource histogram for each resource.

Figure 8.3 illustrates Amanda's activity plan as a bar chart and a resource histogram for analyst-designers. Each activity has been scheduled to start at its earliest start date - a sensible initial strategy, since we would, other things being

equal, wish to save any float to allow for contingencies. Earliest start date scheduling, as is the case with Amanda's project, frequently creates resource histograms that start with a peak and then tail oflf.

Changing the level of resources on a project over time, particularly personnel, generally adds to the cost of a project. Recruiting staff has costs and even where staff are transferred internally, time will be needed for familiarization w ith the new project environment.

The resource histogram in Figure 8.3 poses particular problems in that it calls for two analyst-designers to be idle for eleven days, one for six days and one for two days between the specification and design stage. It is unlikely that IOE would have another project requiring their skills for exactly those periods of time and this raises the question as to whether this idle time should be charged to Amanda's
