The average time required to repair a system or device from the moment of failure until it is fully restored, also abbreviated as MTTR. It is a key maintainability metric used in calculating system availability. MTTR is computed by dividing the total repair time across all failures by the number of failures. A smaller MTTR indicates higher maintainability.
