Which maintenance approach is based on monitoring equipment condition to schedule maintenance before failure?

• A. Reactive maintenance
• B. Preventive maintenance
• C. Corrective maintenance
• D. Predictive maintenance

Answer: (D)

Predictive maintenance relies on monitoring equipment condition to forecast when maintenance should occur before a failure happens. By tracking indicators such as vibration, temperature, lubricant quality, or other performance data, you can estimate remaining useful life and schedule service at the optimal time. This approach reduces downtime and unnecessary maintenance, unlike preventive maintenance which follows fixed intervals regardless of actual wear, and unlike reactive/corrective maintenance which fixes issues after a failure has occurred.
