| Criterion |  DevOps Incident Timeline Analysis |  Product Discovery Test Card |
|---|---|---|
Purposedifferent | For an incident with an unclear sequence, the method makes the timeline precisely visible. It separates perception, reaction, and delay so cause and effect become more clearly readable. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
Complexitydifferent | Medium | Low |
Timedifferent | 60-180 min | 20-35 min |
Participantsdifferent | 3-10 | 1-5 |
