Product Owner
The Product Owner is responsible for the commercial success of the project. He organizes the neccessary work, and optimizes the work already delivered with the help of the Product Backlog. He is the only party that organizes the Product Backlog. This includes the following tasks:
- Exact writing of the items
- Ordering the items to reach goals as efficient as possible
- Optimizing the work done by the Development Team
- Making sure the Product Backlog is available and clear to all parties involved
- Making sure the Development Team understands the items of the Product Backlog
These tasks can be performed by the Product Owner himself, or he may let the Development Team perform them, at his responsibility.
The Product Owner is a single person, but he can and should reflect the visions of a committe or costumer. He is the only person allowed to change the Product Backlog.
A project can only succeed if the decisions of the Product Owner, which are reflected in the content and order of the Product Backlog, are respected.
