Sprint: How to Solve Big Problems and Test New Ideas in Just Five Days
Jake Knapp · Jake Knapp, John Zeratsky, Braden Kowitz Paid Intermediate
This is the clearest playbook for show, don't ask. The five day structure ends with a rough, facade-level prototype in front of five real people on Friday, and you watch their face and hands rather than asking leading questions. Useful even if you compress it to two or three days for a solo founder.
- Build a facade prototype, just realistic enough to react to, not a working product.
- Interview one person at a time and let them think out loud while using it, resist jumping in to explain.
- Confusion and hesitation on their face is more honest data than anything they will tell you afterward.
