What is the role of a Product Owner on a Scrum team?

Avoid offering opinions about what the specific background of a Product Owner should be. The duties are the same regardless of whether the resource is sourced from within the client domain or the development team, as in cases where the business analyst acts as a Product Owner proxy.

A scrum Product Owner is responsible for managing the product backlog. They add user stories, prioritize them, and play a key role in the release and sprint planning. The Product Owner has expertise in the business the product is related to, and they are also responsible for communicating the goals of the product and ensuring that the intended use and value of the items contained within the backlog are understood.
