Corrective Action

13 Root Cause Analysis for Auditors

This course introduces auditors to the fundamentals of root cause analysis and how it supports effective corrective actions. Participants will learn how to distinguish between symptoms and true root causes when reviewing nonconformities. The session covers practical problem-solving tools such as the 5 Why method and the Fishbone (Ishikawa) diagram to help systematically identify underlying causes of process failures.

By the end of this course, participants will understand how to evaluate corrective action investigations, recognize when root causes have not been properly identified, and apply structured methods to ensure problems are addressed at their source rather than repeatedly corrected at the symptom level.
