SixSigma.us. (2017, March 3). What are common root cause analysis (RCA) tools? https://www.6sigma.us/etc/what-are-common-root-cause-analysis-rca-tools/

This educational article provides a detailed overview of the most prevalent root cause analysis (RCA) tools utilized within Lean Six Sigma and quality management disciplines. It explores the functionality and application of essential techniques such as the 5 Whys, Fishbone (Ishikawa) diagrams, Failure Mode and Effects Analysis (FMEA), and Pareto charts. The primary argument is that treating symptoms rather than underlying problems leads to recurring defects; therefore, mastering RCA tools is crucial for identifying the true source of process failures. The author explains how each tool facilitates a structured approach to problem-solving, encouraging teams to systematically investigate operational breakdowns. Aimed at continuous improvement professionals, the resource serves as a practical reference guide to selecting and deploying the appropriate analytical tool to achieve sustainable, long-term resolutions and enhance overall process reliability.
