| Criterion |  Agile Sprint Retrospective |  Knowledge Modeling Feynman Technique |  Knowledge Modeling Concept Mapping |  Operations After-Action Review |
|---|---|---|---|---|
Purposedifferent | When a sprint is over and friction shouldn't simply be carried forward, it opens the view onto collaboration and patterns. It creates space to see causes and changes together. | 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. | Concept Mapping arranges terms and relationships in a network that makes subject-matter connections tangible. It fits when a topic needs to be understood structurally rather than linearly. | After missions or project phases with unclear outcomes, the method makes visible what actually happened and what can be learned from it. It separates course, effect, and causes so experience turns into solid improvement. |
