Mean time to repair is the average time it takes to restore an asset after a failure.
Mean Time To Repair is total downtime divided by the number of repairs. Enter your numbers to get MTTR, then split out the active repair time to see how much of it is actually wrenching versus waiting. For most teams, the wait is the bigger number, and that changes where you go to fix it.
The average time to repair an asset and return it to service, measured from failure to restoration.
Total repair time divided by the number of repairs.
Usually active repair time. If you include waiting, parts, and diagnosis, you are closer to mean downtime.
Better parts availability, job plans, and trained labor. Most repair delay is waiting, not wrenching.
