Which maintenance strategy focuses on ensuring that critical equipment is maintained to maximize life?

• A. Preventative Maintenance
• B. Reliability Centered Maintenance
• C. Predictive Maintenance
• D. Corrective Maintenance

Answer: (B)

Reliability-centered maintenance is about keeping the assets that matter most performing reliably by focusing maintenance on what will preserve function and extend life. It starts by identifying each critical piece of equipment, understanding how it can fail, and what the consequences of that failure would be. With that information, maintenance tasks are chosen and scheduled specifically to prevent those failures and to keep the equipment in a safe, operating state for as long as possible. This approach prioritizes reliability and life extension for the most important assets, rather than simply following a fixed calendar or waiting for failure.

Preventive maintenance uses fixed schedules for all equipment, which can lead to unnecessary work or missed needs. Predictive maintenance relies on condition data to predict when a failure might occur, which is excellent for timing but doesn’t inherently prioritize based on criticality across the whole system. Corrective maintenance is reactive, fixing things only after they fail.
