One thing I've noticed is POs are almost always from the Product Management side. It makes sense, they both have Product in their name. I think this is part of the problem and that at the scrum team level the PO should be an engineer. The issue is that the granularity of a system that should have product management is often larger than the granularity of a single scrum team. You can have several teams working together on a cohesive product. Yet often each team will have it's own product manager acting as PO. This leads to a lot of unnecessary horse trading and suboptimal results.
