A survey-based framework to quantify PMF by asking users how they would feel if they could no longer use the product. The magic threshold is 40% answering 'Very Disappointed'.
Core Principles
- 1.Ask the Magic Question: 'How would you feel if you could no longer use this product?' (Very/Somewhat/Not disappointed).
- 2.Target the Right Segment: Survey active users who have experienced the core value (e.g., used twice in the last two weeks).
- 3.Focus on the 40%: Deeply analyze the 'Very Disappointed' cohort to understand the specific value they derive.
