What is MTTR?

Mean Time To Repair — how fast your team actually gets things running again.

MTTR (Mean Time To Repair) is the average time it takes to diagnose, repair and return a failed asset to service. It measures the responsiveness of a maintenance operation, not the reliability of the asset.

Teams track MTTR by asset class to find where repairs stall — waiting on parts, access permits or diagnostics. Paired with MTBF, it gives a full picture: how often things break versus how quickly you recover.
