Incident Response Plan
A concrete action checklist written out in advance, before anything has gone wrong, specifying exactly what to do first and what to do second the moment something looks off — its purpose is to replace error-prone, on-the-spot judgment made under panic with a fixed, already-thought-through sequence you can simply follow.
