This article comes right on time ! Wow, I was trying to find a way to expose the problem and you did it. The reality is that the product manager is NOT suppose to be able to VETO stuffs. The whole team should agree and aim at achieving the target/OKR and there should be a consensus between “enough to learn/move the needle” and “quality/execution.”
Another thing aswell is depending of the structure you work in, iteration is approached in different ways. Some PM will try a feature, see if it works, then move to another feature, instead of adjusting it, and some other will try to ship something so small to learn that it never really becomes something.
If you guys have any recomendations of other articles to explain our PMs how to be PMs then I am keen to hear about it
