Predictive maintenance is ___.

Predictive maintenance is ___.

• A. Rarely necessary
• B. Maintenance scheduled at regular intervals
• C. Maintaining proper equipment lubrication
• D. Analyzing the condition of an asset using various technologies

Answer: (D)

Predictive maintenance focuses on monitoring the actual condition of equipment and using data from sensors and diagnostic tests to forecast when a component will fail or degrade beyond an acceptable level. By analyzing trends and signs of wear with various technologies—such as vibration analysis, thermography, oil analysis, and other condition-monitoring methods—you schedule maintenance just before failure, reducing unplanned downtime and unnecessary service. This is why analyzing the condition of an asset using different technologies best captures the concept. Fixed-interval maintenance describes preventive maintenance, while lubrication is a specific task, and saying it’s rarely necessary ignores the goal of preventing unexpected outages.
