In this post I'm going to answer the question is there only one root cause to a problem which is a very controversial topic so I actually pull down some Expert Challenges and prove why there is only one-root cause to any problem(at least in my experience).

I'm always happy to be challenged and proven wrong...I keep an open mind so please understand that these are my options and ideas based on 20+ years of experience in Root Cause Analysis. This was also the way I was taught by Japanese teaches while working in Japanese Automotive for over a decade.
