The correct answer is to update the Business Case with risk-adjusted benefits and present it to the board. This is because the PRINCE2 principle of continued business justification demands that the Business Case remain viable throughout the project, especially during Initiation when key decisions are made. By factoring in the 30% risk from market volatility, the expected benefits drop to £910,000, which is below the £1.2 million cost, making the project unviable on a risk-adjusted basis. On the PRINCE2 Foundation exam, this scenario tests your understanding that the Business Case is a living document and must reflect current risks, not just initial estimates. A common trap is to proceed with the original optimistic figures or to ignore the risk quantification. Remember the memory tip: "Risk-adjust or reject"—if a risk materially changes the cost-benefit ratio, you must update the Business Case before the board can approve initiation.
PRINCE2F Project Initiation and Stages Practice Question
This PRINCE2F practice question tests your understanding of project initiation and stages. 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.
You are the project manager for a software implementation project in a large retail company. The project is currently in the Initiation Stage. The senior user has provided the requirements, and the senior supplier has estimated that the project will cost £1.2 million and take 18 months. However, during a review of the Business Case, you discover that the expected benefits are only £1.3 million, giving a benefit-cost ratio of just 1.08:1. Additionally, the market conditions are volatile, and there is a risk that a competitor may launch a similar product before your project completes, potentially reducing benefits by 30%. The project board is eager to proceed but wants assurance that the project is viable. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Update the Business Case with risk-adjusted benefits and present to the board
Option D is correct because the PRINCE2 principle of continued business justification requires that the Business Case be updated to reflect current risks and uncertainties. In this scenario, the market volatility and competitor risk could reduce benefits by 30%, dropping the expected benefits to £910,000, which is below the £1.2 million cost, making the project unviable. Presenting this risk-adjusted Business Case to the board allows them to make an informed decision on whether to proceed, rather than proceeding with an overly optimistic view.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Proceed with the current Business Case as the board is eager
Why it's wrong here
Ignoring risks is not prudent; the board needs full information.
✗
Escalate to the programme manager without updating the Business Case
Why it's wrong here
The PM should first assess and update the Business Case.
✗
Recommend cancelling the project due to poor viability
Why it's wrong here
Too premature; the risk-adjusted case may still be acceptable.
✓
Update the Business Case with risk-adjusted benefits and present to the board
Why this is correct
This provides a realistic assessment for decision-making.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think the board's eagerness (Option A) or escalation (Option B) is sufficient, but PRINCE2 requires the Business Case to be updated with risk-adjusted figures before any decision is made, ensuring continued business justification.
Detailed technical explanation
How to think about this question
In PRINCE2, the Business Case is a living document that must be updated throughout the project, especially when new risks or changes in assumptions occur. The risk-adjusted benefits calculation involves applying the probability and impact of risks to the expected benefits; here, a 30% reduction due to competitor launch would reduce benefits from £1.3M to £910K, making the benefit-cost ratio 0.76:1, which is below the threshold for viability. This aligns with the PRINCE2 requirement that the project must remain desirable (benefits outweigh costs), viable (achievable), and achievable (feasible) throughout its lifecycle.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. During Initiation, the project manager discovers that a key assumption in the Business Case is invalid. What should the PM do first?
hard
A.Ignore the assumption
B.Stop the project
C.Inform the Project Board
✓ D.Update the Business Case
Why D: The Business Case is the key driver for the project, and if a fundamental assumption is invalid, the project manager must first update the Business Case to reflect the new reality. This ensures that the project remains viable and that the Project Board can make an informed decision about whether to continue. Updating the Business Case is the correct first step because it provides the basis for any subsequent decisions, such as escalating to the Project Board.
Variation 2. A project is initiating and the Business Case shows a cost-benefit ratio of 1:1.2. The project board is concerned. What should the project manager do?
hard
A.Reduce scope to lower costs
B.Seek alternative options to improve benefits
✓ C.Provide justification and request approval
D.Recommend project cancellation
Why C: The Business Case shows a cost-benefit ratio of 1:1.2, which is positive (benefits exceed costs). The project board's concern does not automatically invalidate the Business Case. According to PRINCE2, the project manager's role during initiation is to provide the board with the justification (the Business Case) and formally request approval to proceed. Option C is correct because the project manager must present the evidence and seek a decision, not unilaterally change scope or cancel.
