| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Growth Flywheel |  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. | Growth often breaks down where a reinforcing mechanism builds up too much friction. A Flywheel shows the cycle of value, repetition, and reinforcement meant to sustain growth. | 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 | 60-120 min | 25-40 min |
Participantsdifferent | Designers, developers as users, and facilitation | 3-8 | 1-5 |
Formatdifferent | Workshop + async | Workshop | Workshop + async |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | Flywheel Map, Friction Points, Growth Levers, Experiment Backlog | Learning Card with evidence and next action |
