| Criterion |  Agile Specification by Example |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Experiment Canvas |
|---|---|---|---|
Purposedifferent | When business rules need to become precise, it ties language, example, and test together. It sorts work by value, risk, and delivery ability. The result is captured as an Example Table and Acceptance Tests. | 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 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. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 60-90 min pro Feature | 2–4 h review as a planning range; preparation and evaluation additional | 30-60 min |
