A project to upgrade the IT infrastructure of a medium-sized company is in the Initiating a Project process. The project manager has created the Business Case, which shows a net present value (NPV) of £150,000 and an internal rate of return (IRR) of 12%. The project board's executive is concerned that the project may not deliver the expected benefits because the market demand for the new infrastructure is uncertain. The project manager is now preparing the Project Plan. What should the project manager do next?
The Business Case should be updated with risk information to support planning.
Why this answer
D is correct because the Business Case must be refined to reflect the market uncertainty before the Project Plan is created. In PRINCE2, the Business Case is a living document that drives decision-making, and the Project Plan is based on it. Including a risk assessment of the market uncertainty ensures the project board can make an informed decision about whether the project remains viable, given the NPV and IRR are based on assumptions that may no longer hold.
Exam trap
The trap here is that candidates may think the Business Case is static once approved, but PRINCE2 requires it to be continually updated to reflect new risks or changes, and the Project Plan must be based on the most current version of the Business Case.
How to eliminate wrong answers
Option A is wrong because it bypasses the need to address the executive's concern about market uncertainty; approving the Project Plan subject to a later review of the Business Case violates the PRINCE2 principle of continued business justification, as the plan should be based on a current, validated Business Case. Option B is wrong because proceeding with the Project Plan despite known market uncertainty ignores the risk that the NPV and IRR may be invalid; PRINCE2 requires that the Business Case be updated to reflect new risks before planning continues. Option C is wrong because it suggests updating the Business Case to reflect uncertainty but then seeking approval before proceeding with the Project Plan, which is incomplete; the correct action is to refine the Business Case by including a risk assessment (as in D) and then create the Project Plan based on that refined version, not just update and seek approval separately.
