MTTR

Mean Time To Repair

How long it takes on average to clear a breakdown, from the stop to the restart.

Formula

MTTR = Total repair time ÷ Number of breakdowns

MTTR measures the response: time to arrive, diagnose, get parts, and the repair itself. A short MTBF with a short MTTR hurts less than rare breakdowns that last a whole shift.

What it looks like in the system

Breakdown time is measured by the system, not by a note written afterwards. You also see how much of it was waiting.
