Hey Felo, I'm really glad that you liked the article!

As for your question my personal preference is to make companies more product-led and agile-minded which creates the right conditions for there to be only one product role (whether you call that PM or PO is up to you). I find having both to be an anti-pattern more often than not.

This is because as you already hinted at, having a hand-off between them is sub-optimal. It leads one to be making important strategic decisions in isolation of technical feasibility and the other into a highly tactical role, disconnected from their users.

However, in saying that however I have seen places where having both have a) worked and b) made sense. I still would have preferred to have a single role. But yes you are right, with the right collaboration it can work. I talk about a construct to facilitate this collaboration and shared ownership to be successful in a video I made about a year ago - https://www.linkedin.com/posts/ant-murphy_productowner-productmanager-productleadership-activity-6667934005859618816-mcGV

Hopefully that answers your question and you find it helpful :)
