|---|---|---|---|
Purposedifferent | 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. | When it stays unclear who carries responsibility and who only contributes, Responsibility Poker makes the distribution of responsibility explicit. It sharpens the boundaries between weighing in, deciding, and bearing consequences. | When roles, interfaces, or projects fail because of differing expectations, Expectation Mapping surfaces these differences. It shows what each side takes for granted and where the pictures diverge. |
