| Criterion |  Knowledge Modeling Feynman Technique |  Domain Modeling Context Map |  Product Discovery Assumption Mapping |  Product Discovery Learning Card |
|---|---|---|---|---|
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. | When several contexts need to talk to each other, it makes their relationships and dependencies legible. It helps sort integration pressure and responsibilities across system boundaries. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
