| Criterion |  Product Strategy DIBB |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Decision Making Force Field Analysis |
|---|---|---|---|
Purposedifferent | DIBB helps clarify target groups, value, goals, and priorities by making the logic behind a decision explicit. It captures results as a DIBB document, belief list, bet list, and learning report. | 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. | In change initiatives, supporting and restraining forces sit at the table at the same time. Force Field Analysis makes these tensions explicit and shows where change can be pushed forward by strengthening or relieving. |
Complexitydifferent | Low | High | Low |
Timedifferent | 1-2 h | Several meetings plus preparation and analysis; total effort depends on scope | 45-90 min |
