| Criterion |  Product Discovery Fake Door Test |  Operations Failure Mode and Effects Analysis |  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. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
