Is accountable for prioritizing the Product Backlog items
Can be influenced by a committee
The Product Owner creates and orders the Product Backlog items and makes sure that everyone understands them. Estimating the items and breaking them down into tasks are done by the Development Team. There can be a committee for the product ownership, but only their representative will be called the Product Owner. So, theres only one Product Owner, even when there are multiple teams. This person can be full time or part time. One person can have more than one role in Scrum (e.g. both the Product Owner and the Scrum Master). While its not forbidden, its not recommended either.*##**##*
