I look at the Segway as a counter example. Maybe people really did just want a faster way to walk through a city. No offense to Dean Kamen —- he has a very impressive set of accomplishments.
I fully support performing user studies to better understand the problem domain and the feature space. I think your bullet points illustrate some of the challenges in finding the right balance. Unfortunately, I’ve run into way more Segway builders than I have car inventors. They build something based on founder intuition or just bad user studies and then glibly dismiss customer requests as calls for faster horses. I lack the time, energy, and desire to adapt to whatever custom workflow is added because I supposedly don’t know my domain well enough to know what I want.
There’s probably a B2C and B2B split in there, but I’ve never seen that distinction made in application of some of this advice. I know you aren’t advocating for the outright dismissal of user feedback, but I’ve seen that interpretation time and time again. I’d love for us to get a new metaphor or apocryphal story.
