Figure 6: example WBS list
The procedure for creating a WBS is as follows:
1. Define the major activities of the project, treating project management as a separate activity
2. For each activity:
a. Is it hard to estimate the cost or duration of the activity?
b. Is more than one individual or organisational unit responsible for completion of the
activity?
c. Is this activity dependent on any other activities in the WBS?
d. Does the activity contain more than one type of work process?
e. Does the activity involve significant risk?
f.
Will it be difficult to measure the progress of the activity?
If the answer to any of these is yes, then go to step 3, if no, go to step 4
3. Identify logical sub-activities of the activity. For each sub-activity perform step 2
4. Review the activity definition, and refine as necessary
Note that this procedure may be spread out over time, with more detail being added as the scope of
the project becomes better understood. At each stage, the project manager should verify that the
project objectives are achieved with the activities in the WBS
3. Identify Resources
For each activity at the lowest level of the WBS, identify the resources, both in terms of physical
resources (land, energy, materials, machinery etc) and human resources (labour etc) required to
complete the activity.
4. Estimate activity duration
Once the resources required to complete an activity have been identified, an estimate of the activity’s
duration using these resources can be made. If this duration is unacceptable, consider changing the
resourcing level to modify the duration
