An organization has a standardized change management plan that all project managers must adhere to. A project manager has worked with the Change Control Board in his organization to approve a change…

Risk assessment is performed before submitting a change request for approval, not after the CCB has already approved it.

Communicating the change to a vendor may be a subsequent action but is not the standardized first step required by a change management plan after CCB approval.

A cost estimate is developed as part of the change request analysis before CCB approval, not after the change has already been approved.

The Work Breakdown Structure is the foundational decomposition of all authorized project scope, so any approved scope change must be reflected in the WBS to keep it current and accurate. Updating the WBS ensures the project baseline is realigned and all downstream planning artifacts such as schedules and cost estimates remain consistent. According to PMI standards, an approved scope change triggers an update to the scope baseline, of which the WBS is a key component.
