|---|---|---|---|
Purposedifferent | When teams derive needs only from assumptions and real motives are missing, user interviews give direct access to behavior and meaning. Conversations from the target group's everyday life make patterns, tensions, and open questions solidly visible. | 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. | A Business Model Stress Test checks how well a business model holds up under pressure and headwinds. It compares strengths, risks, market logic, and courses of action. The result is captured as a stress-test report and action plan per scenario. |
