Comprehensive incident response framework from detection through resolution and post-incident review. Battle-tested SRE/DevOps practices: severity classification, timeline reconstruction, structured post-incident analysis. Use when handling an outage or production incident, declaring an incident, coordinating multi-team response during an outage, leading a post-mortem, running incident command or emergency response, or setting up on-call practices for a new service. Do NOT use for performing the remediation actions it assigns.
