Ehsan's Insight
Steve Blank's Customer Development is the most important and most incorrectly implemented startup methodology. The original insight — "get out of the building" and talk to customers — is universally accepted. The execution is universally botched. Founders conduct "customer discovery" interviews where they pitch their solution and ask "would you use this?" (the answer is always yes). True customer development asks: "Tell me about the last time you dealt with [problem]. What did you do? How much time did it take? What did you spend?" Those behavioral questions about past actions reveal truth. Hypothetical questions about future behavior are fiction.
