| Criterion |  Knowledge Modeling Feynman Technique |  Architecture ARID (Active Reviews for Intermediate Designs) |  Knowledge Modeling Teach-back |  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. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | Teach-back checks whether an explanation actually got through to the other person. The method makes misunderstandings visible early and strengthens shared understanding in advisory and learning situations. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
Complexitydifferent | Low | Medium | Low | Low |
Timedifferent | 20-60 min | 2–4 h review as a planning range; preparation and evaluation additional | 5-20 min | 25-40 min |
