Root cause analysis
Root Cause Analysis
Root Cause Analysis (pronunciation: /ruːt kɔːz əˈnælɪsɪs/) is a problem-solving method used to identify the underlying reasons or "root causes" of a problem or event. The primary goal of using Root Cause Analysis is to prevent the recurrence of the problem by addressing the root causes, rather than merely addressing the symptoms of the problem.
Etymology
The term "Root Cause Analysis" is derived from its purpose of identifying the "root" or fundamental cause of a problem. The word "root" comes from the Old English rōt, from a Germanic base meaning 'dig', while "cause" is from the Latin causa meaning 'reason', and "analysis" is from the Greek analusis meaning 'a breaking up, a loosening, releasing'.
Definition
Root Cause Analysis is a systematic process for identifying "root causes" of problems or events and an approach for responding to them. Root Cause Analysis is based on the basic idea that effective problem solving requires more than merely "putting out fires" for problems that develop, but finding a way to prevent them.
Methodology
The methodology of Root Cause Analysis includes various tools and techniques such as Fishbone Diagram, 5 Whys, Fault Tree Analysis, and Pareto Analysis. These tools are used to identify the underlying cause or causes of a problem, allowing for the development of effective solutions.
