Which role owns the Business Case in a PRINCE2 project?
The Executive owns the Business Case, being accountable for ensuring the project remains justified and delivers value for money. This satisfies the stem because ownership sits with the single individual representing the business interest, not the Project Manager, who only maintains it.
Why this answer
The Executive is the single individual who owns the Business Case in a PRINCE2 project. This role is ultimately accountable for the project's justification, ensuring that the project remains viable and aligned with corporate objectives throughout its lifecycle. The Executive approves the Business Case and is responsible for its ongoing review and any changes.
Exam trap
The trap here is that candidates often confuse the Project Manager's responsibility for developing and maintaining the Business Case with ownership, but PRINCE2 explicitly assigns ownership to the Executive to ensure clear accountability for the project's justification.
How to eliminate wrong answers
Option A is wrong because the Senior Supplier represents the interests of those providing the project's products and resources, but does not own the Business Case; they contribute to its development and review. Option B is wrong because the Senior User represents the interests of those who will use the project's outputs and is a key stakeholder, but the Business Case ownership rests with the Executive. Option C is wrong because the Project Manager is responsible for developing, maintaining, and managing the Business Case on a day-to-day basis, but does not own it; ownership and ultimate accountability belong to the Executive.
