How to Be a Successful Product Manager

I was just wondering what the structure looks like within your different industries and where you've worked of who owns, right? The product end to end. And I think that ties into a question I want to ask too, which is like, are product managers actually allowed to manage their product? Right? Because I see as exactly to what Tom said, there's always someone above you that feels like they're making the decision. So if you guys could speak on that, that'd be great.
