Root cause analysis is a class of problem solving methods aimed at identifying the root causes of problems or events. The practice of root cause analysis is based on the belief that problems are best solved by attempting to correct or eliminate root causes, as opposed to merely addressing the immediately obvious symptoms. By directing corrective measures at root causes, it is hoped that the likelihood of problem recurrence will be minimized. However, it is recognized that complete prevention of recurrence by a single action is not always possible. Thus, root cause analysis is often considered to be a repetitive process, and is frequently viewed as a tool of continuous improvement.

Root cause analysis, initially is a reactive method of problem detection and solving. This means that the analysis is done after an event has occurred. By gaining expertise in root cause analysis it becomes a pro-active method. This means that root cause analysis is able to forecast the possibility of an event even before it could occur.

A well implemented quality management system will include training and understanding of how root cause analysis tools and techniques can be used to promote continuous improvement.
