| Criterion |  Knowledge Modeling Feynman Technique |  Knowledge Modeling Knowledge Mapping |  Product Discovery Test Card |  Product Discovery Assumption Mapping |
|---|---|---|---|---|
Purposedifferent | The Feynman Technique checks understanding by explaining a topic so that it stays easy for others to understand. It makes knowledge gaps visible before they become costly in everyday work. | Knowledge Mapping makes knowledge, gaps, and transfer paths visible across a field. It fits when expertise should not just exist but also be findable and transferable. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. |
