RCM shifts the focus away from blanket, calendar-based maintenance schedules. It ensures that money is spent preventing failure modes that actually matter, eliminating unnecessary preventive maintenance (PM) tasks.
The SAE JA1011 standard defines a process as RCM if it methodically addresses the following seven key questions in sequence:

What is the asset supposed to do? (e.g., "Keep the pressure at 6 bar.") Functional Failures: How can it fail to do that? Failure Modes:
This step involves selecting "proactive tasks." The standard dictates that tasks must be technically feasible and worth doing. Proactive tasks include scheduled restoration, scheduled discard, or condition-based monitoring (predictive maintenance).

Determining the causes of functional failures. Not today
If you are currently evaluating your maintenance strategies or preparing for an RCM rollout, please let me know:
Hidden failure consequences (failures that aren't apparent to the operating crew under normal circumstances). Safety and environmental consequences. Operational consequences (production and economic losses). Non-operational consequences (direct repair costs only). 6. What should be done to predict or prevent each failure?
To be compliant with SAE JA1011, a process must answer in the following sequence:
