Apollo Root Cause Analysis™ was born out of the Three Mile Island Nuclear Power Plant incident of 1979 when Dean L. Gano was working in the nuclear power industry. Following the event he became involved in many investigations and studies to determine what caused the failures and identify effective solutions. During this process he became aware of the inadequate incident investigation techniques that were available at the time. Over the next 10 years he became a student of human problem solving processes and learned many techniques – none of which worked very well in the real world. After teaching a variant form of conventional Root Cause Analysis for a few years, he developed Apollo Root Cause Analysis™. It is derived from many years of study and application in the real world on real problems. It is simple and can be used by anyone who wants to learn.
