There is no single problem solving process that is capable of producing results in every situation; however, the robust Root Cause Analysis (RCA) process illustrated below can significantly increase the chances of success and prevent recurrence of undesirable outcomes. It is not always necessary to follow the RCA process steps in a sequential order. In order to increase the speed and efficiency of the RCA process many of the process steps can be performed simultaneously. Depending on the impact, probability of recurrence, level of complexity, and other unique circumstances surrounding the event, the depth of analysis and overall scope of the RCA will be considerably different. Given the vast array of tools and techniques suitable for the RCA, it is important to keep the process simple and cost-effective by selecting and using only the most relevant tools for each phase of the process.
