| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Learning Card |  Growth Growth Experiment |
|---|---|---|---|
Purposedifferent | 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. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | When growth ideas surface quickly, the temptation to build immediately instead of learning is high. A Growth Experiment frames an assumption so target group, lever, and measurement are clear before the first deployment. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 25-40 min | 1-2 Wochen |
Participantsdifferent | Designers, developers as users, and facilitation | 1-5 | 1-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Learning Card with evidence and next action | Experiment card, Result summary, Next bet |
