Incident Response
The structured process of recognizing, mitigating, and resolving a system outage.
Detailed Explanation
Incident Response is the fire drill of software engineering. It moves through phases: detection, triage, mitigation (stopping the bleeding), resolution (fixing the root cause), and the postmortem. A mature response prioritizes restoring service for users before conducting a deep forensic analysis.
Chaos is inevitable. A good incident response makes the chaos predictable and manageable.

Common Failure Mode
Practical Example
