PRINCE2F PRINCE2 Practices Practice Question
During a PRINCE2 project, the Project Manager is reviewing the Business Case at the end of a stage. The Benefits Review Plan shows that the expected benefits are still achievable, but the project costs have increased. What should the Project Manager do?
⚠ Common exam trap

Correct answer & explanation
✓
Update the Business Case to reflect the increased costs and reassess the viability

The Project Manager should reassess the justification and update the Business Case to ensure it remains accurate. This supports the continued viability of the project and informs the Project Board's decisions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Take no action because the benefits are still achievable
Why it's wrong here
Even if benefits are achievable, increased costs can affect the project's viability and the Business Case. Ignoring the cost increase would mean the Business Case is not up to date, which could lead to poor decision-making. The Project Manager must ensure the Business Case reflects the current situation.
- ✗
Revise the Benefits Review Plan to show reduced benefits
Why it's wrong here
The Benefits Review Plan is used to track and review benefits, but the scenario states that benefits are still achievable. There is no indication that benefits should be reduced. Revising the plan to show reduced benefits would be incorrect and could undermine the project's justification. The focus should be on updating the Business Case.
- ✗
Escalate to the Project Board immediately without updating the Business Case
Why it's wrong here
While the Project Board may need to be informed, the Project Manager should first update the Business Case to provide accurate information. Escalating without an updated Business Case would leave the Board without the necessary context to make a decision. The Business Case is a key document that should be maintained continuously.
- ✓
Update the Business Case to reflect the increased costs and reassess the viability
Why this is correct
The Business Case must be updated to reflect any changes that affect its viability, including increased costs. The Project Manager should reassess whether the benefits still justify the costs and update the Business Case accordingly. This ensures that the project remains aligned with the business objectives and that the Project Board can make informed decisions.
