Resource Planning Resource planning is forecasting the resources required to perform the scope of work within the time plan. The resource constraint should be considered after the network diagram, schedule bar chart and procurement schedule have been developed, but before the cash-flow statement. Key Points: Compile resource histograms to compare resource forecast and resource availability. Allocate resource to the critical activities first. The cumulative resource manpower S curve is used for the earned value calculation. 2 Dr. Hesham A. Aziz

KEY RESOURCES How many people do you need ? What type of skills do they require ? Are facilities, materials, or supplies essential ? Is information or technology needed ? What is the total cost of project ? Are sufficient funds available ? Look at what each activity requires Identify levels of expertise required Assess who will take on each activity Examine using existing systems Consider the cost of all the resources Check the budget that was agreed PEOPLE OTHER RESORCES M ONEY M an Power M aterial 3 Dr. Hesham A.

The Resource Problem Resources and Priorities Project network times are not a schedule until resources have been assigned. The implicit assumption is that resources will be available in the required amounts when needed. Adding new projects requires making realistic judgments of resource availability and project durations. Resource-Constrained Scheduling Resource leveling (or smoothing) involves attempting to even out demands on resources by using slack (delaying noncritical activities) to manage resource utilization. 4 Dr. Hesham A.

1 . Resource Estimating The resource estimate is linked directly to the scope of work and bill of materials (BOM). The next step is to consider the direct trade-off between the resource requirement and the activity’s duration. Consider the following in the scope of work is to erect 12 tones of steel and the estimator knows from past experience that the work can be done in 150 man-hours per tone and the men work 10 hour shifts, than the equation is: (12 tonnes x 150 man-hrs per tonnes) = 180 man days 10 hrs per day 5 Dr. Hesham A.

2 . Resource Forecasting To forecast the total resource requirement by discipline or interchangeable resource. An interchangeable resource is when you have a pool of workers and any one of them could perform the work. Activity Number: The Resource information is addressed through an activity number. Therefore the timing of the resource can be linked directly with the schedule of that activity . Resource Type: This field is used to distinguish the different types of resource, for example . Quantity per Day:
