Collaboration/Team/Roles and responsibilities


Product owner[edit]

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.
