| Criterion |  Agile Sprint Retrospective |  Product Discovery Riskiest Assumption Test |
|---|---|---|
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. | When an idea hinges on one critical unknown, it prioritizes testing that exact piece of uncertainty first. It separates problem, assumption, solution, and evidence. The result is captured as a prioritized list of assumptions, a test plan, and a result report. |
Complexitydifferent | Low | Medium |
Timedifferent | Up to 3 hours for a one-month Sprint; shorter Sprints are usually shorter | 1-2 Wochen pro Iteration |
Participantsdifferent | Scrum Team | 2-6 |
Formatdifferent | Workshop | Workshop + async |
Outputdifferent | Improvement actions, Team agreements | Prioritized Assumption List, Test Plan, Results Report |
