Correct answer & explanation
✓
Project Manager
The Project Manager is responsible for maintaining the Business Case throughout the project because PRINCE2 requires the Business Case to be a living document that is updated as new information emerges. The Project Manager ensures that the Business Case remains viable by monitoring costs, benefits, risks, and progress against the approved baseline, and by producing regular Highlight Reports and Checkpoint Reports that feed into the ongoing justification. This responsibility is explicitly defined in the PRINCE2 manual under the 'Business Case' management product and the 'Managing a Stage Boundary' process.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
PRINCE2 often tests the distinction between accountability (Executive) and responsibility (Project Manager) for the Business Case, leading candidates to mistakenly select the Executive because they confuse ownership with maintenance.
Detailed technical explanation
How to think about this question
In PRINCE2, the Business Case is a dynamic document that must be formally reviewed at each stage boundary (via the 'Managing a Stage Boundary' process) and at the end of the project. The Project Manager uses the 'Business Case' management product to capture updated cost and benefit forecasts, risk assessments, and any changes in the project's justification. A real-world scenario where this matters is when a project encounters a significant cost overrun or a change in market conditions; the Project Manager must update the Business Case to reflect the new reality and then present it to the Project Board for a decision on whether to continue.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
