Quick Answer
The answer is the Project Brief. This document defines the authority and responsibility of the Project Manager in PRINCE2 because it is created during the Starting Up a Project process and formally establishes the project management team structure, including the Project Manager’s role, reporting lines, and decision-making limits. On the PRINCE2 Foundation exam, this question tests your understanding of how the Project Brief captures the project mandate and translates it into clear accountability for the Project Manager, often appearing as a direct recall item. A common trap is confusing the Project Brief with the Project Initiation Documentation (PID), but remember that the PID expands on the Brief later—the Brief itself is the definitive source for initial authority. Memory tip: think “Brief begins authority”—the Project Brief is the first document to set the Project Manager’s power and responsibility.
This PRINCE2F practice question tests your understanding of overview of prince2 and the project environment. 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.
Which document defines the authority and responsibility of the Project Manager?
The Project Initiation Documentation
Why wrong: The PID supersedes the Project Brief after initiation, but the initial authority is in the Project Brief.
The Stage Plan
Why wrong: Stage Plans detail work for a stage, not overall PM authority.
The Work Package
Why wrong: Work Packages delegate authority to Team Managers.
The Project Brief
The Project Brief includes the Project Manager's authority and is approved by the Project Board.

Correct answer & explanation
The Project Brief
The Project Brief defines the authority and responsibility of the Project Manager because it is created during the Starting Up a Project process and includes the project mandate, which outlines the Project Manager's role, authority levels, and accountability. PRINCE2 explicitly states that the Project Brief contains the project management team structure and role descriptions, making it the definitive document for the Project Manager's authority and responsibility.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
PeopleCert often tests the misconception that the Project Initiation Documentation (PID) defines the Project Manager's authority, but the PID is a later, more detailed document that builds on the Project Brief, which actually establishes that authority first.
Detailed technical explanation
In PRINCE2, the Project Brief is a key input to the Initiating a Project process and is refined into the PID, but the Project Brief itself must include the project management team structure, role descriptions, and the Project Manager's delegated authority from the Project Board. This ensures that the Project Manager has clear, documented authority to manage the project on a day-to-day basis, as per the PRINCE2 principle of 'defined roles and responsibilities'.
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.
