Let's clarify something - I am a strong advocate of Reliability Centered Maintenance (RCM), a methodology developed in 1978 by Nowlan and Heap, for creating robust maintenance strategies. However, it appears that many companies I encounter are moving away from utilizing full-fledged RCM for their maintenance planning. There is a perception that RCM Analysis is more time-consuming and resource-intensive compared to other approaches. Instead, maintenance decisions are often based on past experiences, manufacturer recommendations, root cause analysis, and educated guesses. But are these methods as effective as RCM in preventing failures or minimizing their impact? What are the risks associated with relying on these alternatives instead of RCM? Share your thoughts on this topic.
Is RCM essentially a form of FMEA? Are there significant risks that plants may overlook without implementing RCM?
Many plants have already incorporated maintenance strategies advised by RCM, including modifications, albeit with differing levels of success. Can we consider this as the foundational principles of RCM being applied?
Terrence, the two prominent facilities I assist do not allocate sufficient resources for a comprehensive RCM analysis. The task of organizing all equipment into a detailed spreadsheet and documenting failure modes seems overwhelming to initiate. With a diminishing number of reliability engineers and overall staff in both plants, the focus has shifted towards satisfying shareholders rather than prioritizing RCM. Despite maintaining favorable profit margins, RCM has taken a backseat. Most of the reliability engineers' time is devoted to root cause analysis and liaising with replacement parts suppliers. The approach is more aligned with modified OEM recommendations - waiting for equipment to fail before making decisions during the root cause analysis. Limited attention is given to critical components that have not yet failed, with emphasis primarily on condition monitoring.
Reliability Centered Maintenance (RCM) is undeniably essential for optimizing production and reducing costs. It is not just a one-time task but a continuous improvement process. RCM II may overlook the importance of continuous improvement, which is why asset criticality ranking should precede the RCM process. Both traditional RCM (RCM II) and Streamlined RCM have their place. Streamlined RCM, based on the NAVSEA RCM manual, provides immediate benefits for the top 10% of critical assets, with classical RCM applied later for a more thorough analysis. Involving and motivating technicians is crucial, and training based on the NAVSEA manual has proven to be effective in promoting a deeper understanding of maintenance tasks. With over 30 years of experience as a reliability practitioner, I am ready to kick off the RCM journey as the Reliability Engineer for a manufacturing plant in Indianapolis.
I am a firm believer in Reliability Centered Maintenance (RCM), however, I have doubts about the ability of most plants to fully commit to implementing the process without external regulation or a significant financial consequence. RCM is often marketed as a cost-saving solution, which is true in the long run. For older plants that are heavily reliant on corrective maintenance, RCM can provide insights into the preventive maintenance that can reduce the need for constant repairs. Despite this, it is important to note that these plants cannot entirely eliminate corrective maintenance as it is crucial for keeping the plant operational. This means that initially, they will need to allocate resources to both corrective and preventive maintenance, leading to an increase in manpower and maintenance budget. Many RCM programs struggle to survive this transitional phase.
I strongly concur with your observations. Having worked in the maintenance field for some time, it seems that the shift away from RCM has largely been driven by the perceived complexity and resource-intensive nature of the model. Though this may be true to some degree, it's important to acknowledge the comprehensive scope that RCM brings to maintenance planning, primarily its focus on preserving system function and preventing failures. Alternatives like manufacturer recommendations and root cause analysis, while essential, often don't offer this holistic view. They may be effective in specific circumstances, but might overlook potential threats that RCM could pinpoint. Risks associated with these methods are mainly in the domain of unprecedented failures, which could have a larger impact on operations. Thus, while using these alternatives for maintenance planning isn't entirely wrong, I believe integrating them with RCM could potentially bring about the best results.
