To improve the evaluation of a major or minor nonconformance, Lead auditor, Bart Solomon, developed Decision Tree. This tool is used by Certification Bodies across all QMS, environmental, automotive, aerospace, and occupational health and safety standards.
The Decision Tree provides stronger guidance for third-party auditors to evaluate the parameters of a major or minor non-conformance. However, this evaluation method can be a valuable tool for internal auditors to use as they determine what is producing a non-conforming condition.
