Which role is responsible for the Project Plan?
The Project Manager owns the Project Plan, being accountable for its creation, maintenance and day-to-day management throughout the project. This differs from the Project Board, which approves the plan, and Project Assurance, which monitors it independently.
Why this answer
The Project Manager is responsible for producing and maintaining the Project Plan, as defined in PRINCE2's management products. This includes defining the project's stages, activities, dependencies, and resource estimates, and ensuring the plan aligns with the Business Case. The Project Manager owns the planning process and is accountable for the plan's accuracy and updates throughout the project.
Exam trap
PeopleCert often tests the distinction between responsibility for creating versus approving a plan, leading candidates to mistakenly select the Project Board (Option B) because they confuse approval authority with ownership.
How to eliminate wrong answers
Option A is wrong because the Executive is responsible for the Business Case and overall project justification, not for creating the detailed Project Plan. Option B is wrong because the Project Board approves the Project Plan and provides direction, but does not create or maintain it. Option C is wrong because the Senior User represents user requirements and benefits, but has no direct responsibility for producing the Project Plan.
