The Scrum Product Owner has a tough job. Translating business strategy into product strategy and ultimately into teeny-tiny user stories takes a ton of time and effort. Most Product Managers don’t have the time or inclination to be a good Product Owner and most Business Analysts, the people most likely to fill the gap, don’t actually own the product. I almost always recommend to my clients that a team of people work together to fill this role. I don’t really care about the whole ‘single wringable neck’ thing… all I want is well groomed prioritized product backlog, and I think there is more than one way we can get there.
