| Criterion |  Product Discovery Assumption Mapping |  Growth North Star Metric |  Product Discovery Test Card |
|---|---|---|---|
Purposedifferent | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | When product teams track many metrics, the view of the actual customer outcome easily gets lost. A North Star Metric bundles growth, usage, and value contribution into one signal that makes the system's direction visible. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
