10 Best Software Tools To Conduct Root Cause Analysis and Solve Complex Problems

Root cause analysis (RCA) is a structured evaluation method that is conducted to identify the root causes for a problem or a undesired outcome.

The resulting actions are adequate to prevent recurrence of the problem. A Root Cause Analysis helps to determine what happened, how it happened, and why it happened. Here there are many techniques like 5 Whys, Fault Tree analysis etc. there are few software tools that guide you through the process of performing a RCA. While there is intelligence needed to do a RCA, these software tools are designed so well that it can intelligently guide you through the process and determine the cause. Another advantage of using a software tool to do a RCA is that it would be a independent assessment of the problem was it is machine driven.

    I would also add Causelink to this list. It is an intuitive platform for building cause-and-effect charts, and producing RCA reports. The enterprise version also provides advanced data mining and team collaboration features: http://www.sologic.com/root-cause-analysis-software
