MTTR

What does MTTR stand for and what does it mean?

MTTR is an acronym for Mean Time to Repair.

MTTR is a measure of the maintainability of repairable items—representing the average time required to repair a failed component or device.

MTTR is usually expressed mathematically, as the total corrective maintenance time for failures divided by the total number of corrective maintenance actions for failures over a given time period.
