Which maintenance approach is described as proactive?

• A. Run-to-Failure Maintenance (RTF)
• B. Planned Maintenance
• C. Preventive Maintenance
• D. Predictive Maintenance

Answer: (B)

Proactive maintenance means acting before a fault occurs by planning and doing maintenance ahead of time. Planned maintenance fits this best because it systematically organizes inspections, servicing, and part replacements on a schedule or against usage triggers, ensuring work is done before problems arise. This forward-looking planning reduces unexpected downtime and keeps equipment running smoothly. Run-to-failure is reactive—maintenance happens after a failure. Preventive maintenance also acts before issues but follows fixed intervals and isn’t always organized under a formal, comprehensive plan. Predictive maintenance uses condition data to forecast when a failure will occur and schedule work accordingly; it’s proactive too, but in this context planned maintenance is the clearest example of proactive scheduling.
