Mean Time to Repair (MTTR)

Mean Time to Repair, or MTTR, is a metric used to assess the maintainability and recoverability of IT systems, network components and technical infrastructures. It measures the average time required to identify the cause of a failure, perform the necessary repair activities and restore the affected system to operational condition. A lower MTTR generally indicates more efficient troubleshooting and recovery processes. Automated monitoring, documented troubleshooting procedures, spare parts availability and clearly defined responsibilities can help reduce repair times. MTTR is commonly used in IT service management, network operations and data centre environments. It helps organisations evaluate system availability, service quality and the efficiency of operational maintenance processes.
