The document discusses the business benefits of root cause analysis (RCA) based on a study conducted at Ericsson in the Netherlands. It finds that RCA helped improve business results by identifying over 190 root causes through 12 sessions. The cost of preventative actions was recouped 1.5-2.5 times for design and maintenance projects. RCA was most beneficial for addressing maintenance and customer issues. Key success factors included selecting problems with serious impact, skills in problem analysis and communication, and prioritizing actions that could be implemented.
