Some people, particularly those focused on Scrum, will tell you that Product Owners should also be focused on strategic issues. This is certainly true in simple, non-scaled situations. It is good for POs to understand the long-term strategy for the product that they are focused on. However, there is far more to Product Management than just software development. Furthermore, the day-to-day work with the delivery team, in addition to the day-to-day work required for look-ahead modelling and planning (what Scrum refers to as backlog refinement) with stakeholders, can be more than a full-time job for Product Owners in and of itself.
