Which is a purpose of the Controlling a Stage process?
A . Assign work to be done and take corrective action to ensure that the stage remains within tolerance
B . Provide a fixed reference point at which acceptance for the project product is confirmed
C . Enable the Project Board to be provided with sufficient information to authorize the next stage
D . Enable the organization to understand the work that needs to be done to deliver the project’s products

Answer: A

Explanation:

The purpose of the Controlling a Stage process in PRINCE2® is to monitor and control a stage within its authorized tolerances. During this process, the Project Manager assigns work, monitors work progress, deals with issues, reports stage status to the Project Board, and takes necessary corrective actions to stay within the stage’s tolerances.
