Which maintenance strategy focuses on identifying degradation early and preventing failures through scheduled activities?

• A. Preventive Maintenance
• B. Run-to-Failure
• C. Corrective Maintenance
• D. Reactive Maintenance

Answer: (A)

Preventive maintenance is a proactive approach that aims to prevent problems before they occur by performing maintenance on a schedule based on time or usage. Regular inspections and servicing help spot wear or deterioration early, allowing scheduled tasks like lubrication, filter changes, and component replacements to keep equipment running reliably and avoid unexpected failures.

In contrast, run-to-failure means letting equipment operate until it fails and then repairing it, while corrective maintenance focuses on fixing faults after they occur, and reactive maintenance is essentially responding after a failure. Because this question highlights catching degradation early and taking planned actions to prevent failures, preventive maintenance is the best fit.
