| Criterion |  Product Discovery Problem Interview |  Agile Start Stop Continue |  Agile Sprint Retrospective |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | When the picture of the problem still needs to become solid, it asks about real situations and consequences. It separates genuine suffering from mere interest in a solution. | When a team wants to deliberately adjust its working behavior, it makes habits visible and assessable. It focuses on concrete changes instead of diffuse mood. | 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 Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
