PRINCE2F Practice Question: Overview of PRINCE2 and the project environment
Which PRINCE2 principle emphasizes that the project must remain desirable, viable, and achievable throughout its life?
⚠ Common exam trap
PRINCE2F often tests the confusion between principles, themes, and processes, and candidates may pick 'Manage by Stages' or 'Learn from Experience' when the question specifically describes the ongoing viability of the Business Case.

Correct answer & explanation
✓
Continued Business Justification
The PRINCE2 principle 'Continued Business Justification' states that a project must have a valid Business Case and remain desirable, viable, and achievable throughout its life. This principle ensures that the project is not continued simply because it was started, but because it continues to deliver value. It is one of the seven core principles that must be applied for a project to be considered PRINCE2-compliant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manage by Stages
Why it's wrong here
Continued business justification requires the project to remain desirable, viable and achievable, reviewed at each stage boundary and end stage assessment. Manage by Stages governs how work is planned, delegated and controlled in stages, not the viability test itself. The confusion arises because stage boundaries are where justification is typically re-checked.
- ✗
Defined Roles and Responsibilities
Why it's wrong here
Defined Roles and Responsibilities establishes the Project Board, Project Manager, Team Manager and assurance structures, not the ongoing viability test. Continued business justification is the principle demanding the project stay desirable, viable and achievable. The mix-up is tempting because clear accountabilities support justification decisions, but they are a separate principle.
- ✓
Continued Business Justification
Why this is correct
Continued Business Justification requires the Business Case to be reviewed and confirmed viable, desirable and achievable at every stage, justifying continued investment. This satisfies the stem's emphasis on ongoing desirability, viability and achievability throughout the project's life.
- ✗
Learn from Experience
Why it's wrong here
Learn from Experience concerns capturing and applying lessons, not judging continued business justification. It tempts because lessons genuinely inform viability reviews, but the principle requiring a project to stay desirable, viable and achievable throughout its life is Continued Business Justification.

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. Which PRINCE2 principle emphasizes focusing on the justification for the project?
medium- A.Manage by stages
- B.Tailor to suit the project environment
- C.Learn from experience
- ✓ D.Continued business justification
Variation 2. Which PRINCE2 principle emphasizes that a project must remain viable throughout its lifecycle?
medium- A.Manage by stages
- B.Learn from experience
- ✓ C.Continued business justification
- D.Tailor to suit the project environment
Why C: The 'Continued business justification' principle requires that the Business Case is reviewed and updated regularly to ensure the project remains desirable, viable, and achievable.
Variation 3. Which PRINCE2 principle ensures that a project remains viable by requiring continuous justification of the project's objectives against the benefits?
medium- A.Manage by stages
- ✓ B.Continued business justification
- C.Focus on products
- D.Tailor to suit the project environment
Why B: Continued business justification is the PRINCE2 principle that requires the project's business case to be reviewed and re-validated at every stage boundary and whenever a major change occurs. It ensures the project remains aligned with the organization's objectives and that the benefits still outweigh the costs and risks. If justification is lost, PRINCE2 mandates that the project be stopped rather than continued by inertia.
Variation 4. Which principle ensures that a project remains viable?
medium- A.Manage by Stages
- B.Learn from Experience
- ✓ C.Continued Business Justification
- D.Tailor to Suit the Project
Why C: The Continued Business Justification principle ensures that a project remains viable by requiring ongoing validation of the business case throughout the project lifecycle. If the justification ceases to be valid (e.g., costs exceed benefits or strategic alignment is lost), the project should be stopped. This principle is the foundation for PRINCE2's focus on value for money and risk management.
