* The use of MTTR to stand for Mean Time To Repair is described in BS 4778. In practice MTTR has often been used with no local definition. This leaves ambiguity. It is recommended that the terms used are precisely defined in meaning and scope † R&M is a generic term which embraces the qualities of Availability, Reliability, Maintainability, Durability, RCM and Testability.
