| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Engineering Golden Path |  Product Discovery Test Card |  Product Discovery Experiment Canvas |
|---|---|---|---|---|
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 teams need a reliable default path for frequent use, sprawl quickly emerges without any guiding logic. Golden Path bundles the preferred path so good practice becomes easy and deviation becomes deliberate. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | When experiments become unreadable after the fact, it arranges hypothesis, signal, and learning goal on a single canvas. It separates problem, assumption, solution, and evidence. The result is captured as a Completed Experiment Canvas and a Success Metric. |
