| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Facilitation Dot Estimation |  Product Discovery Assumption Mapping |
|---|---|---|---|
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 size or effort can only be estimated roughly, Dot Estimation condenses the group's experience into a quick range. It turns individual contributions into a visible selection. The result is captured as an Effort Heatmap, Risk Signals, and Discussion Targets. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. |
Complexitydifferent | Medium | Low | Medium |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 5-20 min | 45-60 min |
