The product owner is responsible for preparing and maintaining the product backlog, ensuring it

accurately reflects user requirements, priorities, and acceptance criteria. This role acts as the voice of

the customer, maximizing product value by managing backlog items, ordering them to reflect

business priorities, and clarifying requirements for development teams.

Monitoring stage progress (A) and managing project-level risks (B) are typically roles of the project

manager or risk owner within PRINCE2 governance. The project backlog (C) contains higher-level

requirements for the entire project and is not the product owner's direct responsibility.

The product owner bridges business and delivery, ensuring the team works on the most valuable

features while maintaining clarity and quality of backlog items.
