Lately I've been doing product demos for Isomux.
First one, I didn't ask questions
Second one, I asked questions but then proceeded to demo something unrelated to their answers
Third one, I set up integrations for their own tools (asana, Teams, etc.) ahead of the demo, but I didn't know the tools well enough
As Brian Armstrong says, action produces information. The corollary: every attempt tells you how to do the next one better.
