1. Course Overview

Correcting symptoms may make incidents temporarily disappear, but it does not prevent recurrence. Root cause analysis requires accurate problem description, evidence-based questioning, and verification of each conclusion.

The course “Root Cause Analysis Using 5 Whys” guides participants in defining problems, building a chain of Why questions, and combining 5 Whys with field data, cause-and-effect diagrams, or cause trees.

Through practical scenarios, participants develop the ability to distinguish direct causes from systemic causes, select corrective actions, and set up follow-up mechanisms to prevent recurrence.
