- A
Postpone the decision until the end of the current stage to conduct a full review.
Why wrong: While stage reviews are important, the business case should be reviewed as soon as concerns arise.
- B
Request the project board to review and update the business case immediately. If it is no longer viable, recommend stopping the project.
This aligns with the continued business justification principle.
- C
Tailor the continued business justification principle to allow the project to continue due to its strategic importance.
Why wrong: Principles cannot be tailored; they are universal and must be applied.
- D
Continue with the project as planned because significant investment has already been made.
Why wrong: This ignores the continued business justification principle; sunk costs should not justify continuation.
Quick Answer
The correct recommendation is to request the project board to review and update the business case immediately, and if it is no longer viable, recommend stopping the project. This is because the PRINCE2 continued business justification principle demands that the business case remains valid and the project’s benefits remain achievable throughout its lifecycle; when the senior user flags that market conditions have changed and expected benefits are at risk, the project manager must escalate for an immediate review rather than relying on sunk costs to justify continuation. On the PRINCE2 Foundation exam, this principle is frequently tested through scenarios where a stakeholder argues for continuing based on past investment—a classic trap that confuses sunk costs with ongoing viability. The key memory tip is “justify or stop”: the business case must be reviewed at every stage boundary, and if justification fails, the project must be stopped, regardless of resources already spent.
PRINCE2F Overview of PRINCE2 and Principles Practice Question
This PRINCE2F practice question tests your understanding of overview of prince2 and principles. 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 large-scale IT infrastructure project for a multinational corporation. The project involves deploying new servers across 20 countries, with a budget of $5 million and a timeline of 18 months. The project has been running for 6 months and is currently in its second stage. The project board consists of the executive, senior user, and senior supplier. Recently, the senior user has been raising concerns that the project is not delivering the expected benefits, and the business case may no longer be viable due to changes in market conditions. The senior supplier argues that the project should continue because significant resources have already been invested. The executive is undecided. As the project manager, you need to advise the project board on the best course of action based on PRINCE2 principles. Which of the following should you recommend?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Request the project board to review and update the business case immediately. If it is no longer viable, recommend stopping the project.
B is correct because PRINCE2's continued business justification principle requires that the business case remain viable throughout the project. As project manager, you must escalate to the project board for an immediate review when the senior user raises concerns about benefits and market changes. If the business case is no longer viable, the project should be stopped to avoid further waste of resources, regardless of sunk costs.
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
The trap here is that candidates confuse the 'manage by stages' principle with delaying decisions, or they incorrectly believe that tailoring can override a fundamental principle like continued business justification.
Detailed technical explanation
How to think about this question
Under PRINCE2, the business case is a living document owned by the executive and must be reviewed at least at each stage boundary, but also whenever a threat to viability emerges. The project manager triggers an exception report if the business case is forecast to fail, prompting the project board to decide. In this scenario, the senior user's concerns about market conditions represent a change in the external environment that directly impacts the cost-benefit analysis, requiring immediate board-level action.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

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. A project manager is reviewing the business case for a new software development project. The project is expected to generate significant revenue, but the initial investment is high. According to PRINCE2, which principle is MOST directly being applied when the project manager ensures that the business case remains viable throughout the project?
medium- A.Manage by stages
- B.Learn from experience
- ✓ C.Continued business justification
- D.Tailor to suit the project environment
Why C: The PRINCE2 principle of Continued Business Justification requires that the business case, which documents the project's justification, is reviewed and updated at key decision points (e.g., stage boundaries) to ensure the project remains viable. In this scenario, the project manager is actively verifying that the high initial investment is still justified by the expected revenue, directly applying this principle to avoid proceeding with an unviable project.
