| Criterion |  DevOps Incident Command |  Operations Failure Mode and Effects Analysis |  Product Discovery Test Card |
|---|---|---|---|
Purposedifferent | During an acute incident with several people involved, the method creates a clear leadership and communication structure. It reduces chaos when fast coordination and clean situational awareness are both needed at once. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
