Root Cause Analysis

Root Cause Analysis (RCA):

Root cause analysis is a methodology that is continually evolving. Like most Quality Improvement approaches it is not magic; “there is no silver bullet”. It is the application in a different way of a series of well known, common sense techniques which used in a different combination can produce a systematic, quantified and documented approach to the identification, understanding and resolution of underlying causes of under achieved quality in organisations. Below is a definition, which encapsulates the main points of this technique:

“An objective, thorough and disciplined methodology employed to determine the most probable underlying causes of problems and undesired events within an organisation with the aim of formulating and agreeing corrective actions to at least mitigate if not eliminate those causes and so produce significant long term performance improvement.”

Definitions:

There are a number of difference definitions of RCA

• “An objective, thorough and disciplined methodology employed to determine the most probable underlying causes of  problems and undesired events within an organisation with the aim of formulating and agreeing corrective actions to at least mitigate if not eliminate those causes and so produce significant long term performance improvement.” - Vorley & Tickle, Quality Management (Tools & Techniques), 2002
• “A powerful tool used to identify, record and visually represent the possible causes of a problem” Instead of problems and their effects appearing vast and insoluble, root cause analysis breaks down the problem into smaller, more easily handled chunks represented by a ‘fishbone’ diagram”. - Paul Wilson RCA (ASQC)
• “The investigation and reporting the causes of occurrences to enable the identification of corrective actions adequate to prevent recurrence and thereby protect the health and safety of the public, the workers, and the environment.” - RCA Guidance document DOE Guidelines, Feb 92
