What does "Reasonably Likely" refer to in the context of RCM?

In the context of Reliability Centered Maintenance (RCM), "Reasonably Likely" refers to the method by which an owner/user assesses and anticipates the occurrence of an event, particularly concerning asset performance and failure. This term is used to gauge the likelihood of failure modes based on historical data, operational context, and expert judgment.

In RCM, understanding what is "reasonably likely" helps in prioritizing maintenance strategies and interventions. By evaluating various failure modes and their probabilities, maintenance plans can be developed that focus on the most critical risks, ensuring that resources are effectively allocated to manage asset reliability.

This understanding contrasts with other options, such as the expected lifespan of an asset, which focuses more on longevity than on probability assessments, or the determination of asset value, which deals with financial considerations rather than failure assessments. The probability of asset failure over time is closely related but does not capture the operational perspective that "reasonably likely" entails within the RCM framework. Thus, the focus on the assessment method is pivotal for effective decision-making in maintenance planning.
