- A non-personnel resources matrix
- Non-personnel usage charts
- A non-personnel summary usage chart
A non-personnel resources matrix such as the one you see below displays the following information for every lowest-level component (or work package) in your project work breakdown structure, or WBS:
- The non-personnel resources needed to perform the activities that comprise the work package. (For example, this image shows that you need computers, copiers, and use of a test laboratory to complete the three listed work packages.)
- The required amount of each resource. (For example, the image above suggests that you need 40 hours of computer time and 32 hours of the test laboratory to create a device. The shaded computer usage numbers by week in the image below.)
To estimate the amount of each resource you need, examine the nature of the task and the capacity of the resource. For example, determine the amount of copier time you need to reproduce a report by doing the following:
- Estimate the number of report copies.
- Estimate the number of pages per copy.
- Specify the copier capacity in pages per unit of time.
- Multiply the first two numbers and divide the result by the third number to determine the amount of copier time needed to reproduce your reports.
For example, the chart indicates that Task 1.2.1 requires six hours of computer time in week 1, four hours in week 2, six hours in week 3, and eight hours in each of weeks 4 and 5. You’d prepare similar charts for required copier time and use of the test lab.
Finally, you display the total amount of each non-personnel resource you require during each week of your project in a non-personnel summary usage chart. The information in this chart is taken from the weekly totals in the individual usage charts for each non-personnel resource.
