The quality management tool, Root Cause Analysis (RCA), is used to identify and reconstruct problems and their causes, understanding how and why they occur. The goal is to prevent future occurrences by implementing countermeasures. This is a structured approach to identifying the root causes, contributing to continuous improvement. In addition to gathering information, Casual Factor Charting is conducted to develop event-specific cause-and-effect relationships. All factors gathered during the analysis are incorporated into a Root Cause Map, which serves as the basis for developing countermeasures.
