A maintenance strategy in which upkeep tasks are performed on a fixed schedule (time-based or usage-based) rather than in response to failure or in response to observed degradation. The defining parameters are: (1) a predetermined interval — measured in calendar time, operating hours, cycles, or distance — (2) a prescribed set of actions to be performed at each interval (inspection, lubrication, part replacement, calibration), and (3) the intent that actions precede the failure mode they mitigate. It persists through maintenance schedules, standard operating procedures, and regulatory compliance frameworks.

Definition
Why it is in scope
A human-made maintenance practice of performing scheduled upkeep at fixed time or usage intervals to prevent equipment failure before it occurs, distinct from condition-based (predictive) and corrective (reactive) approaches.

Preventive-maintenance is designed and maintained for the sake of preserving system reliability — performing upkeep before failure occurs to keep reliability high.

Preventive-maintenance requires scheduling to operate. By definition, PM performs upkeep on a fixed schedule (time-based or usage-based). Remove scheduling and PM ceases to function — it becomes corrective or ad hoc maintenance. The removal test passes: without scheduling, PM stops operating.
