I recently had a few discussions about the role of the Product Owner, whether this is different from that of the Product Manager. I often explain that the PO has two faces, one looking towards the business and one towards the team. It is represented by the following illustration.
In the left part the PO is working on the Product vision and a.o. making roadmaps, managing the product Portfolio/Epic backlog. Basically the PO does a lot thinking and talking about what is needed to make a distinguishable and valuable product. A lot of these activities can be Product Manager activities also…. so logically, I get a lot of questions about the difference between the two.
Mellissa Perri wrote a great blog about this topic. I thinks it contains many answers.
