When used in conjunction with RCM strategies, RCFA (Root Cause Failure Analysis) techniques work effectively to not just prevent failures from occurring, but also to prevent the consequences of failures. Because of so much inter-dependence among individual assets, the consequences of equipment failure can be very far reaching. They range from decreased output to safety concerns and product quality concerns.

RCFA is a process used to uncover the root cause of any failure. By determining a list of potential causes for failure, practitioners of RCFA methods can design and identify successful techniques to prevent those failures from occurring. Implementing proactive treatments that attack the cause of the failure means that less time is spent reengineering assets later.

Sometimes avoiding the failure is less cost-effective than avoiding the effects of the failure, however. RCM practices are designed to reduce or avoid negative effects of failures on all aspects of business practice, not only on manufacturing or equipment life. RCM treats the likelihood of failure as a manageable variable in a neutral light, instead of in a negative one.

Using RCFA Practices with RCM Processes

Used cooperatively, RCFA and RCM can provide comprehensive analysis and allow for the development of maintenance techniques that are focused on functionality and user expectations. As long as expectations are fulfilled, RCM and RCFA practices are successful. All types of maintenance have value, and using RCM and RCFA together can give you the tools you need to decide what kind of maintenance--proactive, corrective, and detective-- fulfills user expectations in each possible failure mode.
