What is MTTR?

MTTR, which stands for Mean Time to Repair, is a crucial metric in system management. It represents the average duration needed to diagnose, troubleshoot, and ultimately rectify any issues or malfunctions within a system once they have been identified. This metric plays a vital role in measuring the efficiency and effectiveness of the troubleshooting and repair processes, allowing organisations to gauge their ability to swiftly resolve system malfunctions and minimise downtime.

How to measure MTTR?

Any incident management/collaboration tool you use like OpsGenie, PagerDuty will be able to provide time it takes from the time an incident ticket is created (which depicts the incident identification timestamp) and the time it was marked resolved (the timestamp of when the incident got rectified). MTTR can be measured across teams, products and type of issues and is a good lens to view how well the incidents are managed.

What Is the Difference Between MTTR and MTBF?
MTTR measures the time taken to repair a system after a failure, while MTBF (Mean Time Between Failures) calculates the average time between consecutive failures. These metrics are complementary to each other. While MTTR shows how fast you resolve, MTBF shows how frequently your system fails.
