PRINCE2F Practice Question: Overview of PRINCE2 and the project environment
Which principle ensures that a project remains viable?
⚠ Common exam trap
A common pitfall is confusing the Continued Business Justification principle (which ensures viability) with the Manage by Stages theme (which provides control), leading candidates to incorrectly associate stage-gate reviews with ongoing justification.

Correct answer & explanation
✓
Continued Business Justification
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.
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
Manage by Stages provides control points for authorising work, but it does not itself assess whether the business case still justifies the project; that is continued business justification. It is tempting because stage boundaries are where viability is reviewed, and it would be correct where the question asked how a project is planned, delegated and controlled incrementally.
- ✗
Learn from Experience
Why it's wrong here
Learn from Experience captures and applies lessons to improve delivery; it does not evaluate whether the business case remains valid, which is continued business justification. It is tempting because lessons can inform viability reviews, and it would be the correct principle where the question asked how a project benefits from prior knowledge and experience.
- ✓
Continued Business Justification
Why this is correct
Continued Business Justification requires the business case to be reviewed and revalidated at every stage boundary and exception, so funding continues only while benefits still outweigh costs and risks. This directly satisfies the stem's viability constraint, since a project whose justification lapses is stopped rather than allowed to drift on.
- ✗
Tailor to Suit the Project
Why it's wrong here
Tailor to Suit the Project adapts the method to the project's scale, complexity and risk; it does not assess ongoing desirability, viability and achievability, which is continued business justification. It is tempting because tailoring shapes how reviews are applied, and it would be correct where the question asked how PRINCE2 is adapted to context.
