Which document serves as a formal notice of non-compliance?

The document that serves as a formal notice of non-compliance is the Non-Conformance Report. This report is specifically designed to identify instances where a product, process, or system deviates from predetermined standards or requirements. The Non-Conformance Report details the nature of the non-compliance, the affected components, and typically includes recommendations for corrective actions. It serves not only as a record of the issue but also facilitates communication between relevant parties to ensure that the non-compliance is appropriately addressed.

In contrast, a Quality Assurance Report provides an overview of the quality processes and their effectiveness but does not serve as a formal notice of specific instances of non-compliance. A Compliance Audit involves assessing adherence to regulations or standards, but it reflects on overall compliance rather than issuing formal notices for non-conformities. An Inspection Certificate typically confirms that a product or process meets specified requirements and does not identify or communicate issues of non-compliance.
