| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Innovation Lean Startup |  Product Discovery Outcome-Driven Innovation |
|---|---|---|---|
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 uncertain business assumptions, the method forces the idea into contact with real market reactions early. It separates wishful picture, assumption, and observable behavior, so that learning becomes faster than planning. This translates uncertainty into measurable insight. | Outcome-Driven Innovation clarifies customer problems, solution opportunities, and evidence. It separates jobs, desired outcomes, importance, satisfaction, and opportunity, and captures results as desired outcome statements, an opportunity landscape, and segments by underserved needs. |
Complexitydifferent | Medium | Medium | High |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | Wochen bis Monate je Lernzyklus | Mehrere Wochen |
Participantsdifferent | Designers, developers as users, and facilitation | 2-8 | 2-6 researchers plus sample |
Formatsame | Workshop + async | Workshop + async | Workshop + async |
