Why does PRINCE2 separate the Project Manager role from Project Assurance?
Independence is key to effective assurance.
Why this answer
PRINCE2 separates the Project Manager from Project Assurance to ensure independent oversight of the project's ongoing viability, compliance, and quality. The Project Manager is responsible for day-to-day management and delivery, while Project Assurance provides an objective check that the project remains aligned with business justifications, standards, and controls. This separation prevents the Project Manager from being both the doer and the sole judge of their own work, avoiding conflicts of interest that could compromise governance.
Exam trap
The trap here is that candidates confuse Project Assurance with a support or delegation function, rather than recognizing it as a mandatory independent oversight role that cannot be combined with the Project Manager's responsibilities.
How to eliminate wrong answers
Option B is wrong because PRINCE2 does not define 'technical tasks' as a primary focus for the Project Manager; the role is about management, coordination, and control, not technical execution. Option C is wrong because workload reduction is not the purpose of the separation; the roles are distinct to provide checks and balances, not to lighten the Project Manager's load. Option D is wrong because the Project Board cannot delegate Project Assurance to the Project Manager; doing so would eliminate the independent oversight that the role is designed to provide, violating the principle of separation of duties.
