|---|---|---|---|
Purposedifferent | When a project, incident, or change process is only remembered in fragments, Timeline brings the sequence back into a readable form. It makes turning points, precursors, and after-effects recognizable over the course of time. | 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. | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. |
