ISO 9001 audits are designed to evaluate whether an organization’s Quality Management System (QMS) is effectively implemented, maintained, and continually improved. While many organizations achieve certification successfully, nonconformities are still commonly identified during internal, surveillance, and recertification audits.
Understanding these common nonconformities helps organizations prepare better, avoid repeat findings, and strengthen their quality management systems.
What Is a Nonconformity in ISO 9001?
A nonconformity is a failure to meet:
ISO 9001 requirements
Internal procedures
Customer or regulatory requirements
Nonconformities are usually classified as:
Major nonconformities – systemic failures or breakdowns in the QMS
Minor nonconformities – isolated lapses that do not indicate system-wide failure
Both require corrective action.
Common ISO 9001 Nonconformities Found During Audits
1. Poor Control of Documented Information (Clause 7.5)
This is one of the most frequently cited nonconformities.
Common issues include:
Outdated procedures in use
Uncontrolled documents at workstations
Missing records or incomplete forms
Lack of document version control
Why it happens: Weak document control processes or lack of staff awareness.
2. Inadequate Internal Audits (Clause 9.2)
Auditors often find that internal audits are treated as a formality.
Typical findings:
Audits not covering all ISO 9001 clauses
Lack of auditor competence
Superficial audit reports
No follow-up on audit findings
Internal audits should identify real gaps—not just confirm compliance.
3. Ineffective Corrective Actions (Clause 10.2)
Organizations frequently close nonconformities without addressing root causes.
Common problems:
No root cause analysis
Corrective actions that only fix symptoms
Repeated nonconformities
Lack of effectiveness review
Auditors expect evidence that corrective actions prevent recurrence.
4. Weak Management Review (Clause 9.3)
Management review is a key leadership requirement, yet often poorly implemented.
Common issues include:
Missing required inputs
Lack of top management participation
No documented decisions or actions
No follow-up on previous review actions
This often signals weak leadership involvement in the QMS.
5. Unclear Quality Objectives and KPIs (Clause 6.2)
Quality objectives must be measurable and monitored.
Typical nonconformities:
Objectives not aligned with quality policy
No measurable targets
KPIs not monitored or reviewed
Staff unaware of quality objectives
Objectives should drive performance, not just exist on paper.
6. Poor Risk-Based Thinking (Clause 6.1)
ISO 9001 requires organizations to identify and address risks and opportunities.
Auditors often find:
No documented risk assessment
Risks identified but no actions taken
Risk management not integrated into processes
Risk-based thinking should be embedded in daily operations.
7. Lack of Competence and Training Records (Clause 7.2)
Organizations must ensure employees are competent for their roles.
Common findings:
Missing training records
No competency criteria defined
No evaluation of training effectiveness
Competence goes beyond qualifications—it includes skills and experience.
8. Inconsistent Process Implementation (Clause 8)
Auditors compare documented procedures with actual practice.
Nonconformities arise when:
Staff do not follow procedures
Processes vary without justification
Changes are not controlled
Consistency is central to quality management.
9. Poor Control of Nonconforming Outputs (Clause 8.7)
Organizations often struggle with managing defects and errors.
Typical issues include:
Nonconforming products not clearly identified
No records of corrective actions
Products released without proper authorization
Effective control prevents defective outputs from reaching customers.
How to Avoid ISO 9001 Nonconformities
Organizations can reduce audit findings by:
Conducting meaningful internal audits
Training staff on ISO 9001 requirements
Strengthening document control
Performing proper root cause analysis
Ensuring effective management review meetings
Proactive system management is key.
Conclusion
ISO 9001 nonconformities are not failures—they are opportunities for improvement.
By understanding the most common audit findings and addressing root causes, organizations can strengthen their QMS, improve performance, and achieve smoother audits.
A well-implemented ISO 9001 system not only passes audits but delivers consistent quality and long-term business value.
