Collaboration/Team/Roles and responsibilities

Product owner

The product owner, in a nutshell, is ultimately responsible for the product or service to be delivered. The product owner is responsible for:

Providing vision for the product or service being developed
Being the single point of escalation for contending priorities among stakeholders
Managing the product road map
Making final decisions about trade-offs when desired functionality, or scope, exceeds the capacity of the team
Defining the target constituent for iterations, releases, and the overall product
Making final decision about whether or not work done on stories is complete ('acceptance').
Doing the work of determining what features the team should work on in order to achieve our user, community, and Foundation goals. This is done in collaboration with the team
Making sure that our products have a coherent, compelling user experience

Because the product owner has the final say over prioritization, there should be only one person acting as product owner.
