The product owner works with the users, or customers, to define how a product can address their needs and wishes.
As the intermediary between the user and the development team, the product owner defines the product scope and requirements.
The product owner is sometimes called a product manager or a marketing manager. If your organization has a project office, that group may include people who function as product owners.
The product owner's primary focus is on the content of the product. The details of implementation planning and scheduling will affect and be affected by the product owner's work, but they are not the product owner's direct concern.
In TeamForge, the product owner's main focus is the feature tree. This is the part of the interface where discussions of product features are organized and tracked.
This is just a vague summary of the product owner's role. For more detail, see [list of resources].
