|---|---|---|---|
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. | 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. | 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. |
