The Mean Time To Resolution (MTTR) is a key metric used to measure the efficiency of an organization’s incident response process. It is defined as the average amount of time it takes for an organization to resolve an incident or service disruption. The MTTR metric is important for organizations to measure and understand how quickly they can resolve incidents and restore services to their customers. It is also used to help organizations identify areas of improvement in their incident response process and ensure that they are providing the best possible service to their customers. The MTTR metric is also used to compare the performance of different organizations and to identify trends in incident resolution times. By understanding the MTTR metric, organizations can better understand their incident response process and ensure that they are providing the best possible service to their customers.
