What is the difference between a Request for Change and an Off-specification in PRINCE2?
Correct. This is the key distinction.
Why this answer
In PRINCE2, a Request for Change (RFC) is a formal proposal to change a product's specification, baseline, or agreed-upon configuration, while an Off-specification is a notification that a product does not meet its agreed specification or that a planned product cannot be delivered as defined. The RFC seeks approval for a change, whereas the Off-specification reports a deviation that has already occurred or is inevitable.
Exam trap
The trap here is that candidates confuse the direction of the issue: an RFC is about changing the specification for future products, while an Off-specification is about a product already failing to meet the current specification, and PRINCE2 tests this distinction by offering options that blur the roles or urgency.
How to eliminate wrong answers
Option A is wrong because both RFCs and Off-specifications can be raised by any project stakeholder, not exclusively by the Project Manager or Team Manager; the Project Manager is responsible for reviewing and escalating them, but the raising party is not restricted. Option B is wrong because urgency is not a defining characteristic of an RFC; an RFC can be urgent or routine, and an Off-specification can also be urgent if it threatens project delivery. Option D is wrong because RFCs and Off-specifications are distinct concepts: an RFC proposes a change to a product's specification, while an Off-specification reports a failure to meet the existing specification.
