Incident Response Metrics Worth Tracking (Beyond MTTR)
Most engineering teams track exactly one incident response metric, and it is usually MTTR. It appears on the quarterly slide, it goes up or down by a few minutes, someone says "we need to bring that down," and nothing about the next incident changes. The problem is not that teams measure the wrong thing out of laziness. The problem is that incident response metrics are genuinely hard to design, and a single average duration is the easiest number to produce from an incident tracker.
