Steve Blank's customer development beats Lean Canvas, Design Thinking and every framework you've heard of — because it forces you out of the building.
- Run 20 problem interviews before writing code. Ask:
- "Walk me through the last time you faced [problem]."
- "What did you do? What did you wish existed?"
- "How much time/money did it cost you?"
