| Criterion |  Growth A/B Testing |  Knowledge Modeling IBIS |  Product Discovery Test Card |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | When two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. | IBIS structures thinking about complex questions as a sequence of issues, ideas, and arguments. The method keeps discussions open without forcing them into premature consensus. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
