The Five Whys – Root Cause Determination

The¬†5 Whys¬†is an iterative question-asking¬†technique¬†used to explore the¬†cause-and-effect¬†relationships underlying a particular problem.¬†The primary goal of the technique is to determine the¬†root cause¬†of a¬†defect¬†or problem. (The “5” in the name derives from an empirical observation on the number of iterations typically required to resolve the problem.)
