Scrum describes a separation of roles; the product owner is accountable for achieving business objectives and the team for technical execution. A pragmatic and collegial relationship between a product owner and team can satisfy the definition of collaboration and honor roles while barely tapping or actually working against the potential of a project and its participants. This paper surveys literature to describe different forms of collaboration, to establish that deep, unbounded collaboration is at the heart of agile values, and that partnerships of high trust and shared risk lead to value and innovation. Finally, this paper incorporates a real- world example of a product owner who, while remaining accountable to the outcome, shared ownership over vision, priorities and execution with her Scrum/XP development team.
