- Explain the evidence, root cause method, containment, corrective action, validation, and documentation.
- Show judgment around standards, repeatability, data quality, supplier controls, production impact, and prevention.
- End with fewer defects, stronger controls, closed CAPA, cleaner audit evidence, or improved customer quality.
