A Project Manager is planning the next stage and updates the Project Plan. In which process is this activity performed?
Correct. SB updates the Project Plan and produces the next Stage Plan.
Why this answer
Updating the Project Plan when planning the next stage is a key activity in the Managing a Stage Boundary process. This process is specifically designed to provide the Project Board with information needed to approve the next stage, which includes updating the Project Plan to reflect the current stage's actuals and the revised plan for the remainder of the project.
Exam trap
The trap here is that candidates confuse 'Controlling a Stage' (which handles day-to-day work) with 'Managing a Stage Boundary' (which handles stage-end planning and plan updates), leading them to incorrectly select option D.
How to eliminate wrong answers
Option B (Directing a Project) is wrong because this process covers the Project Board's decision-making and overall project oversight, not the detailed planning and plan updates performed by the Project Manager. Option C (Initiating a Project) is wrong because this process creates the initial Project Plan and PID, but updating the plan during stage boundaries occurs later in the project lifecycle. Option D (Controlling a Stage) is wrong because this process focuses on day-to-day management of work packages and issue handling within a stage, not on planning the next stage or updating the Project Plan.
