What is Mean Time To Repair (MTTR)?

Mean time to repair (MTTR) is a metric that you can use to measure the average time it takes to troubleshoot and fix a failure of some kind. It demonstrates how fast an organization can respond to a particular issue and correct it.

Before you can calculate MTTR, you first need to determine the amount of time spent between the commencement of an incident and when it was resolved. This takes into account the time that it takes to notify technicians, diagnose the problem, repair the problem, and everything that is required to get the asset up and running again. But it doesn't take into account the amount of time spent waiting for parts.

To calculate MTTR for a specific period, divide the total amount of time spent to fix an asset during the period by the amount of times that the asset needed repair in the period. Generally, MTTR is represented in hours.
