| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Opportunity Solution Tree |  Product Discovery Learning Card |
|---|---|---|---|
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. | When discovery keeps swinging between goals, ideas, and learning loops, it creates clear steering logic. It connects the desired outcome, opportunities, and experiments into a legible structure. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 1-2 h Setup, laufend | 25-40 min |
Participantsdifferent | Designers, developers as users, and facilitation | 2-6 | 1-5 |
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 | Opportunity Solution Tree, Experiment Backlog, Learning Log | Learning Card with evidence and next action |
