Reliability Centered Maintenance (RCM)

The RCM methodology is used to develop or optimize the maintenance program for physical assets. The final outcome of an RCM program is the implementation of a strategy to help companies ensure that any physical asset, system or process continues to do whatever its users want it to do in its present Operating Context. Increasing equipment reliability is key and can result in any number of positive outcomes; namely, reduced downtime, improved safety, increased productivity, and reduced overall maintenance costs.

Four principles guide an effective RCM program:

  • Preserving system functions as the primary objective.
  • Identifying failure modes that can impact system functions.
  • Prioritizing the failure modes.
  • Finding solutions to manage the likelihood of occurrence or the consequences of the failure modes (or both).

The RCM process identifies the functions of the assets that are most vital and then seeks to maximize maintenance strategies so that system failures are eliminated or kept at a minimum and equipment reliability is increased. It entails asking seven questions about the asset or system under review:

  • What are the functions and associated performance standards of the asset in its Present operating context?
  • In what ways does it fail to fulfill its functions?
  • What causes each functional failure?
  • What happens when each failure occurs?
  • In what way does each failure matter?
  • What can be done to predict or prevent each failure?
  • What should be done if a suitable proactive task cannot be found?

The RCM process provides powerful rules for deciding whether any failure management policy is technically appropriate and worth doing. It also provides precise criteria for deciding how often routine tasks should be done.

Our founder, John Moubray developed a profound and unique way to perform RCM analyses – RCM2™ (RCMII™) was developed from the original work done by Nowlan and Heap. One of the features of RCM2™ that distinguishes it from other interpretations of the RCM philosophy is the cross-functional groups of users and maintainers that perform the analyses. After training, these analysis teams apply the process to their assets to produce the most cost-effective asset reliability programs.
