| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Knowledge Modeling Shape-First Modeling |  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. | Shape-First Modeling defines data quality through shapes before implementation or integration frays at the edges. The approach fits when validation and data contracts should be part of the design from the start. | 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 | Halber Tag pro Domain Slice | 20-35 min | 25-40 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1-4 | 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 | SHACL or ShEx Shapes, Validation Reports, Data Contracts, Shape Documentation | Test Card with a pre-set threshold | Learning Card with evidence and next action |
