As a Product Owner, I don’t know what questions to ask.

I don’t know exactly where the conversation is going when I speak with stakeholders. I have a general feel but their responses could take us in an entirely new direction that we never thought to explore. I usually start with “what drives your business” or “what makes people want to buy from you more than once” and go from there. It’s usually followed up with “how do you know you’re getting more or less successful” or “point to what you’ve given up on”. If you get past the “it’s fine” you’ll find that there is a never-ending stream of things to improve on. From that list you’ll begin to put together a list of backlog items.
