| Criterion |  Knowledge Modeling PARA Method |  Product Discovery Opportunity Solution Tree |  Knowledge Modeling Feynman Technique |  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. | When discovery keeps swinging between goals, ideas, and learning loops, it creates clear steering logic. It connects the desired outcome, opportunities, and experiments into a legible structure. | 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. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
