The document discusses the key rules and principles of quality auditing: 1. Audits provide information to management about the future and how to improve performance. 2. Auditors must be properly qualified and trained to perform audits objectively. 3. Audits measure processes against agreed upon criteria like procedures and specifications. 4. Audit conclusions should be based on analyzed facts rather than subjective opinions. The overall goal of auditing is to provide management confidence that quality controls are in place and effective to continually improve performance related to key business priorities like costs, production and risk.
