PRINCE2F PRINCE2 Practices Practice Question
Who is responsible for maintaining the Business Case throughout the project?
⚠ Common exam trap
A common mistake in PRINCE2 is to confuse accountability with responsibility. Although the Executive is accountable for the Business Case, the Project Manager is responsible for its day-to-day maintenance. Candidates often select the Executive because they think ownership implies maintenance, but PRINCE2 assigns the operational maintenance role to the Project Manager.

Correct answer & explanation
✓
The Project Manager
The Project Manager is responsible for maintaining the Business Case throughout the project because they manage day-to-day activities, track progress against the Business Case, and escalate any deviations to the Executive. PRINCE2 assigns this operational responsibility to the Project Manager to ensure continuous alignment with the project's justification.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Executive
Why it's wrong here
The Executive is accountable for the project's overall viability and approves the Business Case at key decision points, ensuring its continued justification. However, the Executive does not undertake the ongoing, day-to-day maintenance of the Business Case throughout the project. That specific responsibility, involving regular review and update to reflect project progress and external changes, is assigned to the Project Manager. This option is tempting as the Executive is ultimately responsible for the project's continued justification and benefits realisation.
- ✓
The Project Manager
Why this is correct
The Project Manager maintains the Business Case throughout the project.
- ✗
The Project Assurance
Why it's wrong here
Project Assurance monitors compliance with standards but does not own the Business Case; the Executive is accountable for its ongoing justification and approval. This option tempts because Assurance reviews the Business Case for viability, yet lacks the authority to maintain or update it—a responsibility tied to the Senior User’s and Senior Supplier’s input under the Executive’s direction. In a scenario where the question asked who verifies the Business Case’s alignment with corporate governance, Project Assurance would be correct.
- ✗
The Senior User
Why it's wrong here
The Senior User represents the users but does not maintain the Business Case.
