Reliability centered maintenance and root cause analysis should be used in tandem as part of a holistic preventive maintenance strategy. For RCM, determining proper asset criticality is necessary for an effective RCM strategy. Improper equipment data management and planning within your CMMS/EAM can lead to RCM implementation issues or knowledge gaps.
Concerning RCA, defining the right trigger events is an important balancing act that many organizations struggle with. Too few triggers will allow for chronic failures to continue, while too many triggers cause excessive costs on unnecessary RCAs.
Another common problem is not with the analysis itself, but with implementing the identified corrective action following an RCA – failure to “close the loop”. Once an RCA is conducted and preventive action items are decided, nobody within the organization confirms that the preventive action is implemented. This leads to the cause being correctly identified, but not adequately addressed.
