MTTR (Mean Time to Repair or Mean Time to Recovery) is a metric used to measure the average time it takes to repair a system or restore it to normal operation after a failure or disruption. It includes the time spent detecting, diagnosing, and fixing the issue. MTTR is important for evaluating operational efficiency and minimizing downtime, as a lower MTTR leads to faster recovery and less impact on business continuity. It is commonly used in IT, cybersecurity, and incident response to assess how quickly issues are addressed. Learn more: https://en.wikipedia.org/wiki/MTTR
