| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Growth Pirate Metrics AARRR |  Product Discovery Smoke Test |
|---|---|---|---|
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. | For products with complex usage paths, overall growth alone is too coarse to reveal bottlenecks. Pirate Metrics breaks the relationship with the product into consecutive stages and shows where the funnel actually leaks. | When demand only needs to be roughly verified, it tests interest with minimal effort. It measures whether people would take a next step at all. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 1-2 h Setup, laufend | 1-5 Tage |
