Mean time to restore answers a blunt question: when something breaks, how fast do you get back to healthy? It is one of the four DORA metrics, and it pairs with change failure rate to describe stability. A team can ship fast and still be fragile - MTTR is where that fragility shows up, in hours of downtime and lost trust.
Watch the shape of the distribution, not just the average. One multi-day outage can inflate the mean and hide a team that normally recovers in minutes, which is why this tool also surfaces the median and the worst case. If your mean and median diverge sharply, your problem is tail risk - rare but painful incidents - not everyday response. Learn the full picture in our DORA metrics guide and lead time for changes.
Estimates are a fine start, but real MTTR comes from real incident and deployment data, not memory. Pair this with the DORA metrics calculator, explore how FeatureFactory helps you measure delivery, or browse the rest of our engineering guides.
