Define the term "preventive maintenance."

The term "preventive maintenance" refers to routine maintenance activities that are conducted to prevent potential breakdowns and ensure that equipment operates efficiently. This approach involves regular inspections, servicing, and minor repairs carried out before issues arise, rather than responding to failures after they occur. By implementing a preventive maintenance strategy, organizations can extend the lifespan of their machinery, enhance performance, and reduce the likelihood of unexpected downtime.

The concept contrasts sharply with reactive maintenance methods, which involve fixing equipment only after it has failed, as stated in the other choices. These reactive strategies can lead to higher repair costs, unplanned downtime, and increased wear on equipment over time. Preventive maintenance, on the other hand, aims to identify and address minor issues before they escalate into major problems, ultimately improving overall operational efficiency and reliability.
