My Dad was basically a tool salesman for most of my life. He was really, really good at it. and I don't know if he ever measured anything. He just talked to people and tried his best to give people what they say they want
Crazy how successful he has been off of just that simple approach. It's something that drives me nuts about a lot of current product design strategies. Yes, sure. You can occasionally have a Steve Jobs style product visionary who delivers something that people never imagined
But for most of us I think we'd see a lot more success just talking to customers and delivering what they ask for, instead of filtering thier thoughts through a "product owner" who winds up having us build something else
My experience with a lot of current product direction advice is along the lines of "don't just give them what they ask for, because they don't know what they want. You have to figure out what they want and deliver that instead". I think this is a really stupid approach. If you are talking to people who "don't know what they want", then you have to find different people to talk to. In my experience the best ideas come from people who know exactly what they want.
The job of product should be to find those people and ask them, not to talk to the wrong people and guess at what they "really want"
