Reliability-Centered Maintenance (RCM), the maintenance management strategy originally developed in the 20th century by the airline industry to assure the reliability of jetliners, has for several decades been utilized by well-run facilities as an advanced maintenance management tool. This presentation will provide an introduction to RCM principles and to the comprehensive, risk-based approach to facilities management that RCM provides. The speaker will describe the transition from reactive and time-based maintenance strategies to proactive, condition-based methodologies that optimize asset performance, safety, and cost-efficiency. The presentation also outlines the RCM decision tree, aligning maintenance actions with regulatory standards (such as NFPA), and highlights the importance of continuous improvement, training, and data-driven decision-making. Case studies also will be included. The information can help move your facility to a very improved level of efficiency
