Top 10 ISO 9001 Audit Findings From a Former Certification Auditor

Common ISO 9001 Nonconformities, Audit Findings & Certification Mistakes

One of the questions I get asked most often is:

"What do auditors actually look for during an ISO 9001 audit?"

Having worked as both a management systems consultant and a third-party Certification Auditor, I've audited organisations ranging from small businesses to large multi-site manufacturers. Whilst every organisation is different, certain findings appear time and time again.

The good news is that most ISO 9001 nonconformities are entirely preventable when organisations understand what auditors are looking for.

Top 10 ISO 9001 Audit Findings

1. Uncontrolled Documents

Document control remains one of the most common ISO 9001 findings. Auditors frequently identify outdated procedures, obsolete forms and employees using documents that are no longer approved.

2. Quality Objectives Not Monitored

Many organisations establish quality objectives but fail to review progress against them. Common findings include missing performance data, lack of monitoring and objectives that have not been updated.

3. Training & Competence Records Missing

Missing training records, expired qualifications and inadequate competency assessments are regularly identified during ISO 9001 audits. Auditors often sample personnel records to verify competence requirements have been met.

4. Supplier Approval Processes Not Followed

Supplier controls are a common weakness within Quality Management Systems. Findings often include incomplete supplier evaluations, missing performance reviews and suppliers being used without formal approval.

5. Internal Audits Not Completed

Internal audits are a mandatory requirement of ISO 9001, yet many organisations fail to complete their audit programme. Common findings include overdue audits, incomplete reports and findings that remain open.

6. Management Reviews Lack Evidence

Management Reviews should demonstrate leadership involvement and oversight of the Quality Management System. Auditors often identify missing agenda items, incomplete records and a lack of meaningful review data.

7. Corrective Actions Not Effective

Many organisations address issues without identifying the underlying cause. Repeat nonconformities, ineffective root cause analysis and overdue actions are commonly identified during audits.

8. Customer Feedback Not Evaluated

ISO 9001 places significant emphasis on customer satisfaction. Common findings include complaints not being analysed, feedback not being reviewed and limited evidence of improvement actions being taken.

9. Risks & Opportunities Not Reviewed

Risk-based thinking is embedded throughout ISO 9001. Auditors frequently identify outdated risk registers, unreviewed risks and opportunities that have not been evaluated or acted upon.

10. Processes Not Followed In Practice

Perhaps the most common finding of all. Whilst procedures may exist, auditors often identify situations where employees are following different processes, records are missing or controls are not being applied consistently.

Why These Findings Matter

Most ISO 9001 nonconformities are not caused by poor intentions. They usually occur because systems are not reviewed regularly, responsibilities are unclear or processes have drifted over time.

The purpose of an audit is not to catch people out. A good audit should provide confidence that processes are working effectively whilst identifying opportunities for improvement.

By understanding the types of findings commonly raised during certification audits, organisations can focus their efforts on the areas that genuinely matter.
