Quick Answer
The answer is the Project Manager, who is responsible for maintaining the Business Case throughout the project. This is correct because PRINCE2 defines the Business Case as a living document that must be continuously reviewed and updated to reflect actual costs, benefits, and risks, ensuring the project remains viable against its original justification. The Project Manager performs this ongoing maintenance, monitoring deviations and escalating any loss of viability to the Project Board for a decision. On the PRINCE2 Foundation exam, this question tests your understanding of the Project Manager’s day-to-day responsibilities versus the Project Board’s approval authority; a common trap is confusing the Project Manager’s maintenance role with the Senior User or Executive, who only provide input or approve changes. To remember this, think: the Manager manages the case, the Board decides its fate.
This PRINCE2F practice question tests your understanding of prince2 practices. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
Project Manager
In PRINCE2, the Project Manager is responsible for maintaining the Business Case throughout the project. This includes monitoring the project's viability against the Business Case, updating it with actual costs and benefits, and escalating any deviations to the Project Board. The Project Manager ensures the Business Case remains a living document that reflects the current justification for the project.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Senior Supplier
Why it's wrong here
The Senior Supplier represents the supplier side.
Senior User
Why it's wrong here
The Senior User represents the users, not the Business Case.
Project Board
Why it's wrong here
The Project Board collectively owns the Business Case, but the Project Manager maintains it.
Common exam traps
The trap here is that candidates often assume the Project Board, as the ultimate decision-making body, is responsible for maintaining the Business Case, but PRINCE2 explicitly assigns this maintenance role to the Project Manager.
Detailed technical explanation
The Business Case is a key PRINCE2 management product that is developed during the Starting Up a Project process and maintained throughout the project. The Project Manager uses it to assess whether the project remains viable, comparing planned vs actual costs and benefits. If the Business Case shows the project is no longer justified, the Project Manager must escalate to the Project Board for a decision on whether to continue.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PRINCE2F exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
