| Criterion |  Systems Thinking System Dynamics Simulation |  Architecture ARID (Active Reviews for Intermediate Designs) |  Product Discovery Fake Door Test |
|---|---|---|---|
Purposedifferent | System Dynamics Simulation makes assumptions about time, delay, and feedback testable through experiments. It draws relationships, patterns, and feedback loops. The result is captured as a simulation model and scenario reports. | 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 demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. |
Complexitydifferent | High | Medium | Medium |
Timedifferent | Mehrere Tage bis Wochen | 2–4 h review as a planning range; preparation and evaluation additional | 1-5 Tage |
