The approach is used in manufacturing, engineering, information technology, healthcare, transport, and safety-critical industries. It supports
Typical workflow includes defining the problem, collecting data, reconstructing a timeline of events, generating and evaluating
Common methods include the five whys technique, Ishikawa (fishbone) diagrams, fault tree analysis (FTA), and failure
The output is usually an RCA report or CAPA plan with identified root causes, contributing factors, responsible
Best practices emphasize cross-functional teams, evidence-based reasoning, avoiding blaming individuals, maintaining traceability of data, and validating
