The Movie Director

The Product Owner drives the project from the business point of view and is responsible for Return on Investment (ROI).

She communicates a clear Vision of the product and defines its main characteristics. She is the one to accept the product increment of the Team at the end of a Sprint.

The Product Owner's main responsibility is to ensure that the Team only works on those Backlog Items that are worthwhile for the Customer.

She has the same goals as the Team, therefore she helps the Team do its work during a Sprint by not disturbing its members and by promptly providing them with the necessary information.
