Staffing management plan. The staffing management plan is a component of the human resource management plan that describes when and how project team members will be acquired and how long they will be needed.

5.6.2.1 Variance Analysis
Variance analysis is a technique for determining the cause and degree of difference between the baseline and actual performance. Project performance measurements are used to assess the magnitude of variation from the original scope baseline. Important aspects of project scope control include determining the cause and degree of variance relative to the scope baseline (Section 5.4.3.1) and deciding whether corrective or preventive action is required.
