Root Cause Analysis (RCA)
An in-depth process or technique for identifying the most basic factors underlying a variation in performance or problem. The main focus of RCA is on systems and processes and not on individuals. It is essentially a method or series of actions taken to determine why a particular failure or problem exists and to establish a means of correcting the causes. RCA Frameworks include: Five Whys, Pareto Analysis, Cause and Effect Diagrams, Tree Diagram and Brainstorming/Interviewing.
