Who is responsible for managing the project's day-to-day activities within the tolerances set by the Project Board?
The PM manages the project day-to-day.
Why this answer
In PRINCE2, the Project Manager is responsible for the day-to-day management of the project within the tolerances set by the Project Board. This includes planning, monitoring, and controlling project activities, escalating issues or deviations that exceed tolerances. The Project Board sets the overall direction and tolerances but does not manage daily tasks.
Exam trap
The trap here is that candidates often confuse the Project Manager's operational authority with the Team Manager's delivery focus, or mistakenly think the Project Board handles daily tasks because it 'manages' the project at a high level.
How to eliminate wrong answers
Option B (Senior User) is wrong because the Senior User represents the interests of those who will use the project's products and is responsible for specifying requirements and benefits, not for day-to-day management. Option C (Project Board) is wrong because the Project Board provides overall direction, approves plans, and sets tolerances, but does not manage daily activities. Option D (Team Manager) is wrong because the Team Manager is responsible for delivering specific products within a work package, but the Project Manager retains overall day-to-day management responsibility for the project.
