| Criterion |  DevOps Blameless Postmortem |  Facilitation World Café |  DevOps Incident Command |
|---|---|---|---|
Purposedifferent | After an incident with damage or a near miss, the method creates a sober field for learning without assigning blame. It directs attention to the course of events, conditions, and effective countermeasures. | When a group needs to connect many viewpoints in a short time, World Café creates a calm alternation between closeness and rotation. It sets thinking in motion without forcing the conversation into full-plenary rigidity. | 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. |
