What does CBM stand for in maintenance strategy?

• A. Predictive-maintenance based approach
• B. Condition-Based Maintenance
• C. Corrective Maintenance Model
• D. Preventive Maintenance Plan

Answer: (B)

Condition-Based Maintenance means performing maintenance when the equipment’s actual health shows deterioration, rather than on a fixed schedule or after a failure. This relies on condition monitoring data—like vibration, temperature, lubricant quality, or wear debris—to detect when a component is trending toward failure and needs service. Acting on real health signals helps prevent unexpected breakdowns while avoiding unnecessary work. The other options describe different approaches: preventive maintenance follows a calendar or usage interval without checking condition, corrective maintenance happens after a failure, and predictive maintenance uses models to estimate remaining life, whereas CBM centers on triggering action from current condition.
