Who is responsible for ensuring that project assurance is independent of the Project Manager?
The Project Board owns the project's assurance responsibilities and must ensure project assurance is independent of the Project Manager. It appoints assurance roles that report to the board rather than to the Project Manager, preserving objectivity and preventing the manager from reviewing their own work.
Why this answer
The Project Board is responsible for ensuring that project assurance is independent of the Project Manager. This is because the Project Board provides overall governance and oversight, and project assurance is a key function that must be objective and separate from the day-to-day management activities of the Project Manager. The PRINCE2 principle of 'defined roles and responsibilities' explicitly assigns this accountability to the Project Board to maintain the integrity of the assurance function.
Exam trap
The trap here is that candidates often confuse the Project Manager's responsibility for managing the project with the Project Board's responsibility for ensuring independent oversight, leading them to incorrectly select the Project Manager as the answer.
How to eliminate wrong answers
Option A is wrong because the Team Manager is responsible for delivering the work within a work package, not for ensuring the independence of project assurance. Option B is wrong because the Project Manager is the person being assured, so they cannot be responsible for ensuring the independence of the function that oversees them; that would create a conflict of interest. Option C is wrong because Project Support provides administrative and clerical services to the project, not the governance or independence of assurance.
