| Criterion |  Decision Making Pre-Mortem |  Decision Making Delphi Method |  Product Discovery Test Card |
|---|---|---|---|
Purposedifferent | In early initiatives with many uncertainties, planning quickly turns too optimistic. A pre-mortem makes the expected failure visible in advance and sharpens the view of causes, gaps, and countermeasures. | 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 Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
