Common areas of non-compliance in ISO 9001 audits include failing to adhere to the organization's own policies and procedures, inadequate documentation, and insufficient record-keeping. To proactively address these issues, organizations should ensure they comply with their documented policies, maintain clear and comprehensive documentation, and implement robust record-keeping systems. Regular internal audits, employee training, and management commitment to quality can also help identify and address potential non-conformities before they become significant issues.
