PM stands for?

PM stands for?

• A. Predictive Maintenance
• B. Planned Maintenance
• C. Preventive Maintenance
• D. Performance Monitoring

Answer: (C)

Preventive Maintenance is maintenance performed on a schedule to prevent failures and keep equipment operating reliably. It’s proactive, time- or usage-based, and aimed at avoiding unexpected downtime by addressing wear and performance issues before they cause problems. In the context of commissioning and building operations, this includes routine tasks like filter changes, lubrication, belt checks, calibration, and inspections that preserve efficiency and safety. Predictive Maintenance, by contrast, relies on monitoring condition data to decide when a device should be serviced, rather than following a fixed schedule. Planned Maintenance refers more to the process of organizing and planning maintenance activities, which can encompass preventive tasks but doesn’t itself specify the proactive, failure-prevention focus that preventive maintenance embodies. Therefore, Preventive Maintenance is the best match for the meaning of PM.
