| Criterion |  Product Discovery Outcome-Driven Innovation |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture C4 Model |
|---|---|---|---|
Purposedifferent | 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. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. |
Complexitydifferent | High | High | Low |
Timedifferent | Mehrere Wochen | Several meetings plus preparation and analysis; total effort depends on scope | 1-4 h |
