RCA+ is a state decomposition method aimed at finding root causes of problems and describing these root causes as TRIZ contradictions. The current rules to apply the RCA+ methodology are balanced between speed of application and the quality and depth of insights. In this research alternatives methodologies of constructing the RCA+ contradiction tree are investigated and 2 templates have been developed and validated. Significant improvements were found in the width and depth of analysis as well as the level of better understanding of the problem being studied.
