Process audits play a crucial role in supplier quality management. Here’s why they are relevant:

Assessing Supplier Processes: Process audits involve evaluating the supplier’s processes, procedures, and practices. By examining how the supplier operates, the customer gains insights into the effectiveness of their quality control mechanisms.

Identifying Nonconformances: During process audits, auditors look for deviations from established standards, including nonconformances. If multiple nonconformances are identified, they become key areas for improvement.

Root Cause Analysis: While process audits may not directly include root cause analysis (RCA), they provide the necessary context for identifying root causes. Auditors can ask questions, review documentation, and observe practices to uncover underlying issues.

Verification of Corrective Actions: As part of the improvement plan, the supplier must take corrective actions to address nonconformances. Process audits verify whether these corrective actions have been implemented effectively.

Continuous Improvement: Process audits contribute to the supplier’s continuous improvement efforts. By identifying weaknesses and suggesting improvements, they help enhance overall performance.

In summary, process audits provide a comprehensive view of the supplier’s operations, allowing the customer to address nonconformances and drive quality improvement. While root cause analysis is essential, it is often conducted separately based on the findings from process audits12.
