What is Mean Time to Repair?


Mean time to repair (MTTR) is a key performance indicator for maintenance teams used to determine how quickly issues are being resolved. It measures the average time to bring failed components or equipment back to full operation. MTTR is made up of several intervals in the maintenance process:

Why it Matters

The goal of maintenance is to take proactive steps to avoid equipment breakdowns and unexpected failure.

Nevertheless, studies have shown that 82% of equipment failures happen in a random failure pattern, meaning that preventative maintenance alone will never be sufficient to avoid all issues.

When faults do occur, the time it takes for that issue to be resolved is critical. The longer it takes, the more long-term damage is likely occurring to the machine.

Mean time to repair is the average length of time, usually measured in hours or days, between when an issue first occurs to when the machine is fully operational.

How to improve MTTR

The best way to decrease mean time to repair is to adopt technology. Equipment monitoring helps to improve this metric with real-time performance data. Enertiv’s equipment monitoring solutions helps to improve MTTR by:

  1. Capturing continuous equipment data with sensors to detect faults immediately
  2. Reducing the time to diagnose the problem by identifying patterns in the data that indicate what the root cause of the issue is
  3. Giving specific instructions and troubleshooting steps to operators to reduce the time to repair the equipment.
  4. Integrating with work order ticketing and other systems to reduce cumbersome administrative work and manual reporting.
