Maintainability is the ease and speed of the system restoring to the normal operational status that is to prevent unexpected working condition, to maximise a life cycle of equipment and facilities, and to maximise efficiency, reliability, and safety operations. The Maintainability is the probability of performing a successful repair or replace using the prescribed practices and procedures for serviceability and reparability. This is similar to system reliability analysis except that the random variable of interest in maintainability analysis is time-to-repair rather than time-to-failure.
