> Term
incident rehearsal
A simulated exercise where engineering teams practice their response to a hypothetical production failure.
Detailed Explanation
Incident rehearsal involves injecting artificial faults or walking through disaster scenarios to test monitoring, alerting, and human response procedures. The goal is to build muscle memory, uncover gaps in runbooks, and ensure teams know what to do when a real outage strikes.
Why It Matters
You do not want engineers reading a runbook for the very first time at 3:00 AM during a massive database failure. Rehearsals turn panic into routine execution.
Common Failure Mode
Practical Example
Production Manifestation
Scheduled war-room exercises where engineers work through a synthetic outage, checking dashboards, communicating status, and executing mitigation strategies without impacting real users.
Frequently Asked Questions
What is incident rehearsal in short?
A simulated exercise where engineering teams practice their response to a hypothetical production failure.
What is the most common failure mode?
Treating the rehearsal as a box-ticking exercise where everyone just nods along to the runbook without actually testing if the alerts fire or if they have the necessary database access rights.
