|---|---|---|---|
Purposedifferent | When knowledge is distributed and direct dominance should be avoided, groups quickly fall under the sway of their opinion leaders. The Delphi Method gathers assessments iteratively and gradually brings expert judgments closer together. | 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. | McKinsey 7S checks whether Strategy, Structure, Systems, Shared Values, Skills, Style, and Staff fit together. Organizational misalignments become visible across multiple levers as a result. |
