Why is it important that there is only one Product Owner per product?
A. The Scrum Master knows who will be his back-up whenever he is unavailable, it saves the organization time and money, and the Development Team knows who to request tasks from.
B. It is clear who is accountable for the ultimate success of the product, the Development Team always knows who determines priorities, and it helps avoid barriers to effective communication and rapid decision-making.
C. It isn’t important as multiple Product Owners can easily share a single Product Backlog.
