How to calculate MTTR
Divide the total repair time by the number of repairs. Count from the moment of failure until the asset is back in operation, not just the time with tools in hand.
In practice, the repair itself is often the smallest part. Break it down into the 5 stages (detection, response, diagnosis, repair and testing) to see where the waiting is.

Frequently asked questions
What is MTTR?
MTTR (Mean Time To Repair) is the average time to get equipment back into service after a failure.
What is the MTTR formula?
MTTR = total repair time ÷ number of repairs in the period.
How do you reduce MTTR?
Measure each stage separately. The gain is usually in detection, travel and waiting for parts, not in the repair work itself.
