| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Facilitation Mind Mapping |  Product Discovery Test Card |  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 a topic is still unclear and too many thoughts surface at once, Mind Mapping creates an open surface for ordering them. It makes connections, subtopics, and starting points visible without fixing them too early. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
Complexitydifferent | Medium | Low | Low | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 15-45 min | 20-35 min | 25-40 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1-10 | 1-5 | 1-5 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Mind Map, Topic Clusters, Open Questions | Test Card with a pre-set threshold | Learning Card with evidence and next action |
