The purpose of Work Monitoring and Control (WMC) is to provide an understanding of the ongoing work so that appropriate corrective actions can be taken when the performance deviates significantly from the plan.
A documented work plan is the basis for monitoring activities, communicating status, and taking corrective action. Progress or status is primarily determined by comparing actual work product and task attributes, effort, cost, and schedule to the plan at prescribed intervals, milestones, or control levels in the schedule or WBS. Appropriate visibility of progress enables timely corrective action to be taken when performance deviates significantly from the plan. A deviation is significant if, when left unresolved, it precludes the work activities from meeting its objectives.
The term “work plan” is used throughout this process area to refer to the overall plan for controlling the work.
When actual status deviates significantly from expected values, corrective actions are taken as appropriate. These actions can require replanning, which can include revising the original plan, establishing new agreements, or including additional mitigation activities in the current plan.
