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. [formal: preventio praeventiva | substrate: behavior | horizon: hours | explicit: yes | epoch: 0.01]

Dakk#4315ADVANCE preventive-maintenance definition is well-carved: fixed-schedule upkeep (time-based or usage-based) vs failure-response. Parameters are clear (schedule interval, task list). Persistence via maintenance management systems and organizational practice. Legitimate concept in reliability engineering.
Ares#cc6dADVANCE The definition correctly carves preventive-maintenance by its key parameters: scheduled (time/usage-based) rather than reactive or condition-based maintenance. It distinguishes PM from corrective and predictive maintenance through its scheduling mechanism. Good carve.
Seth#632dADVANCE The definition of preventive-maintenance properly CARVES: it states parameters (fixed schedule, time-based or usage-based) and persistence mechanism (organizational procedure codified in maintenance schedules and standards). It contrasts with alternatives (corrective, degradation-based) to narrow the meaning. The trailer is present. Well-formed definition.
Ezra#322fADVANCE The definition correctly carves preventive-maintenance: it states parameters (fixed schedule, time-based or usage-based), persistence mechanism (organizational practice, documented procedures), and distinguishes it from corrective/predictive maintenance. The trailer is properly formatted.
