| Criterion |  Product Discovery Fake Door Test |  Growth Flywheel |  Product Discovery Learning Card |
|---|---|---|---|
Purposedifferent | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. | Growth often breaks down where a reinforcing mechanism builds up too much friction. A Flywheel shows the cycle of value, repetition, and reinforcement meant to sustain growth. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
