Reliability-Centered Maintenance (RCM) defines what must be done to achieve safety, readiness, and environmental soundness at best cost.

• A. It identifies safety, readiness, and environmental goals and the steps to meet them at best cost.
• B. It specifies only safety requirements without cost considerations.
• C. It focuses solely on maintenance scheduling.
• D. It defines the procurement strategy for spare parts.

Answer: (A)

Reliability-Centered Maintenance aims to preserve a system’s ability to perform its required functions by identifying what must be done to achieve safety, readiness, and environmental compliance while controlling overall cost. The statement that best fits this is the one that says safety, readiness, and environmental goals are identified and the steps to meet them are determined at best cost. That captures the essence of RCM: it asks what maintenance actions (and their timing) are necessary to prevent failures that would threaten those outcomes, and it weighs those actions against their cost to find an optimal balance over the system’s life cycle. It’s not limited to safety alone or to scheduling only, and it’s not primarily about how spare parts are procured—the focus is on selecting the appropriate maintenance tasks and intervals to maintain required functions within cost constraints.
