MTTR
(Mean Time to Repair)
The average time it takes to diagnose and fix something after it fails
What's it for?
Shows how long repairs usually take after something fails.
For example…
After improving runbooks and monitoring, average repair time for payment outages drops from two hours to twenty minutes
If engineers take an average of 45 minutes to diagnose and repair failed network switches, the repair MTTR is 45 minutes
Think of it like…
Average time for a breakdown truck to get you moving again—not how often you break down
