What does MTTR stand for?

Explanation:
MTTR is the average time required to repair a failed item and bring it back to working condition. In practice, you track how long repairs take for multiple incidents, sum those repair times, and divide by the number of repairs to get the mean. This metric helps teams understand how quickly issues are resolved and informs planning for staffing, spares, and maintenance processes. It’s different from MTBF (mean time between failures), which measures how long a system operates before something fails, and from MTTF (mean time to failure), used for non-repairable items. The other phrases don’t reflect the standard terminology for this downtime-after-failure repair metric.
