3. Audit Process
|
Preparation
|
Execution
|
|
Review past audit reports, process documentation, and QMS records. Develop an audit checklist that aligns to the specific processes or activities.

Conduct interviews, examine records, and observe operations. Collect objective evidence to verify compliance. Identify and document non conformities or opportunities for improvement.
|
4. Non Conformance Reporting

- Categorize non conformities (e.g., major or minor) based on their potential impact on product quality or regulatory compliance.
5. Audit Report
Compile a formal report summarizing:
- Audit objectives, scope, and criteria.
- Observations, including non conformities, and positive findings.
- Recommendations for improvement.
- Evidence of the documents or areas where the non conformance has been identified.
Share the report with the Management Representative and relevant personnel.
