How often should internal audits be conducted and what do they typically review?

• A. At planned intervals (e.g., annually); review SOP compliance, QC results, data integrity, training, CAPA effectiveness
• B. Only when problems arise
• C. Every quarter with no standard scope
• D. As part of external audits only

Answer: (A)

Internal audits are a proactive, scheduled check of the quality system. They should happen at planned intervals so the organization continually verifies that controls are working, not just when problems occur. The typical review scope includes how well standard operating procedures are followed, quality control results, data integrity across records, the status of training and competency, and how effectively corrective and preventive actions have been implemented. This combination ensures ongoing compliance, early detection of weaknesses, and tangible improvements over time through CAPA cycles. Reactive audits driven only by problems miss systemic issues, quarterly audits without a defined scope can become unfocused, and relying solely on external audits ignores internal process evaluations and ongoing improvement.
