|---|---|---|---|
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. | With unevenly distributed speaking time, the method brings every person into the contribution one after another. It prevents early voices from setting the direction while still producing a shared idea space. This makes participation plannable and the team's diversity visible. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
