During the Controlling a Stage process, the Project Manager identifies that the project is forecast to exceed the agreed cost tolerance for the current stage. What should the Project Manager do?
Correct. When a tolerance is forecast to be exceeded, the Project Manager must raise an Exception Report to the Project Board and await direction.
Why this answer
When a tolerance is forecast to be exceeded, the Project Manager must escalate to the Project Board via an Exception Report — this is PRINCE2's management by exception principle. The Project Manager cannot unilaterally decide to exceed tolerances; that requires Project Board authorisation. Option A is wrong because closing the project immediately is not the appropriate first response.
Option B is wrong because continuing without escalation violates management by exception. Option D is wrong because the Project Manager cannot increase the budget without Project Board approval.
