ACE Tools - RRCA

Remember the criteria states that you must use a variety of RRCA tools.  The 5 Why's are not the only Root Cause tool – the right methodology should be chosen depending on the type of problem.  Other tools such as the Root Cause Tree, Fishbone, Event Tree, Multi Vari, Concentration diagrams etc. are effective tools that yield good results for many business problems. There should be at least one RRCA expert in each site.
