| Criterion |  Knowledge Modeling PARA Method |  Knowledge Modeling Feynman Technique |  Product Discovery Smoke Test |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | The PARA Method organizes knowledge into Projects, Areas, Resources, and Archives. It creates order when digital notes, files, and tasks no longer cleanly fit current work. | 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 demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
