EU-GMP Deviation Management: A Structured Lifecycle Approach

Chapter 1.8 (vii) of the EU-GMP Guidelines requires that significant deviations are documented, investigated to identify root causes, and followed by appropriate CAPA. This establishes that deviations trigger a structured process rather than isolated events.

The process begins with formal documentation and written approval, typically within batch records, ensuring traceability and compliance. Once recorded, a risk-based and structured investigation must be conducted, as outlined in ICH Q10, with efforts aligned to the level of risk. Even when root causes are unclear, scientifically justified conclusions are expected, and human error must not be assigned without excluding systemic issues.

Based on findings, corrective and preventive actions are defined and implemented. Their impact on product quality, safety, and efficacy must be assessed, particularly by the Qualified Person. Effectiveness checks, trend evaluation through Product Quality Review, and continuous improvement complete the lifecycle, supported by strong quality culture and robust root cause methodologies.
