Quick Answer
The Business Case is the correct choice because it is the PRINCE2 practice that formally defines the reasons for undertaking a project and ensures continued justification throughout its lifecycle. This practice requires that the project’s benefits, costs, risks, and timescales are regularly reviewed and updated, so the project remains desirable, viable, and achievable; if the justification ever weakens, the project must be stopped. On the PRINCE2 Foundation exam, this concept tests your understanding that the Business Case is the driving force behind all decision-making, and a common trap is confusing it with the Project Plan, which focuses on how the work is done rather than why. A reliable memory tip is to think of the Business Case as the project’s “permission slip”—without a valid one, the project should not proceed.
This PRINCE2F practice question tests your understanding of prince2 practices. 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.

Correct answer & explanation
Business Case
The Business Case practice is the correct answer because it is the PRINCE2 practice that specifically defines the reasons for initiating a project and ensures that the project remains desirable, viable, and achievable throughout its lifecycle. It provides the justification for continued investment by requiring regular review and update of the business justification, which is documented in the Business Case. Without a valid Business Case, the project should be stopped.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
PeopleCert often tests the distinction between the Business Case practice and the Plans practice, as candidates may mistakenly think that the project's justification is derived from the project plan rather than from the Business Case document.
Detailed technical explanation
The Business Case is the key document that captures the business justification, including costs, benefits, risks, and timescales. It is developed during the Starting up a Project process and is refined in the Initiating a Project process. The Senior User is responsible for specifying the benefits, while the Executive owns the Business Case and is accountable for ensuring the project remains justified. If at any point the Business Case is no longer viable, the project must be stopped, as per the PRINCE2 principle of continued business justification.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
