| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Knowledge Modeling Concept 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. | Concept Mapping arranges terms and relationships in a network that makes subject-matter connections tangible. It fits when a topic needs to be understood structurally rather than linearly. | 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 | Medium | Low | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 1-2 h | 20-35 min | 25-40 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1-8 | 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 | Concept Map, Relationship Labels, Knowledge Gaps | Test Card with a pre-set threshold | Learning Card with evidence and next action |
