I was at a pizza party the other day and ran into exactly the sort of person I’m trying to figure out how to help with dexio. He was happy to chat, but I didn’t have any paper. Crisis!
So much information comes across in a good conversation, it’s hugely wasteful to try to keep it all in your head. When you just remember it, you end up with a general feeling (“he liked it!”) instead of all the specifics about that person’s workflow, current solutions, and particular pains.
Customer development isn’t serious business–it’s just asking questions and then caring about the answer. Everyone’s happier if you take the time to write it down, even if you have to do something as silly as using a bunch of paper plates.
(And as it turned out, he quite enjoyed my solution. People like to know that the time they spend helping you won’t be wasted)
