Which maintenance strategy is NOT acknowledged by RCM?

Reliability-Centered Maintenance (RCM) is a systematic approach that focuses on determining the most effective maintenance strategy for physical assets. It emphasizes understanding the function of assets and the consequences of their failure.

The strategy that is not acknowledged as part of RCM is corrective maintenance. This approach is typically reactive, initiated after a failure has occurred, and focuses on repairing or fixing equipment once it breaks down. RCM, however, prioritizes proactive and predictive maintenance strategies that can either prevent failure from occurring or mitigate the risk of failure impacting operations.

In contrast, scheduled maintenance involves performing maintenance activities at predetermined intervals, which helps in minimizing the chances of failure. Inspection strategies are designed to monitor the condition of equipment to detect potential issues before they result in failure. Deferred maintenance refers to the intentional decision to postpone maintenance tasks, but it is still recognized by RCM due to the understanding that some maintenance can be prioritized over others without immediate detrimental impacts.

Thus, corrective maintenance does not fit within the RCM framework, which centers around proactive strategies aimed at optimizing reliability and performance.
