Define predictive maintenance.

Predictive maintenance refers to the practice of monitoring key performance indicators (KPIs) and using data-driven insights to determine when maintenance should be performed, specifically when these indicators suggest that a system's performance may be failing or degrading. This approach allows for maintenance to be carried out just at the right moment to prevent unexpected breakdowns and costly downtime, rather than relying on arbitrary schedules or waiting for a failure to occur.

By utilizing predictive maintenance, organizations can reduce maintenance costs, extend the life of their equipment, and enhance overall operational efficiency. This method leverages techniques such as condition monitoring, data analysis, and trend recognition, making it a proactive strategy that emphasizes the need for timely intervention based on actual system performance rather than estimations or assumptions.
