ROOT-CAUSE ANALYSIS Effective root-cause analysis focuses on human and physical causes for any failure. GET TO THE Root Of the Cause THE CONCEPT OF ANALYZING FAILURES and tragedies to prevent them from recurring isn't new. It is, in fact, the foundation of many of our legal systems and regulatory entities. The United States Pure Food and Drug Act of 1906 is a good example. Enactment of this legislation, which effectively created the Food and Drug Administration (FDA), was in response to the negative impact of dangerous and/or misbranded food and drugs on public health. Among other things, people wanted scientifically tested medicines with controlled ingredients and dosages-not snake oil. Formal failure-analysis documentation began to appear in the defense, automotive, aerospace, and nuclear-power industries in the mid-twentieth century. What started with simple techniques, such as the Five Whys, evolved into more sophisticated approaches, such as Events & Causal Factor Analysis, and 28 | MAINTENANCE TECHNOLOGY If you're good at root-cause analysis, you learn from your mistakes. If you're great at it, you prevent mistakes from happening. David J. Mierau, P.E., CMRP Life Cycle Engineering (LCE) Management Oversight and Risk Tree (MORT). Today, there are hundreds, if not thousands, of methods for performing root-cause analyses across nearly every industry. How good are your skills in this area? Leverage application knowledge Engineers are classically trained in mathematics and physical sciences. We are taught to evaluate, analyze, and calculate. Most current engineering curricula contain courses that include problem-solving elements, something that's often intertwined with root-cause analysis (RCA). To be as effective as possible at RCA, however, engineers need to be able to combine process and theory with strong application knowledge. While they must understand RCA fault-tree methodology inside and out, without a working OCTOBER 2015
