I found this old drawing I made for a customer a couple of months ago. I had some difficulty to explain what a Product Owner should do in our project so I decided the best way is to visualize it. And of course I had a lot of fun drawing it :)
It doesn't show all, mainly the what and how of the sprint itself is not drawn, but it gives some insights of the things a Product Owner should do. I made some extra remark at the denial ( "no") of some ideas by the Product Owner. I really think this is super important so the team only will work on things the PO himself decided that should be done. Otherwise you will have a situation that the team will build something the PO himself is not rely believing in and is unable to give to right instructions about what to build because he does not really believe in it.
