Kadmar Consultants’ technical experts have been in the Quality Management field for more than a decade. Below are the 10 most common IATF 16949 nonconformities organizations face worldwide — along with real-world causes and proven strategies to prevent them.
Getting IATF 16949 certified is not just a requirement — it’s a gateway to new business opportunities with OEMs and Tier 1 manufacturers. It provides the framework for your organization’s Quality Management System. Many organizations still struggle during surveillance or re-certification audits due to recurring nonconformities.
Let’s understand these IATF 16949 nonconformities and how to eliminate them — not just before the audit, but to stay competitive and maintain customer trust.
Why It Happens: Documents are not treated as living tools but as one-time tasks. Procedures are outdated or ignored, and reviews are not performed regularly, leading to dependence on tribal knowledge.
How to Avoid It: Control all documents with unique numbers, review quarterly, link PFMEA–CP–WI, and communicate revisions effectively.
Kadmar Tip: Implement a document control matrix linking every process to its current version.
2. Customer-Specific Requirements (CSRs) Not Integrated
Why It Happens: OEMs like Ford, GM, and Stellantis have unique CSRs, and suppliers often struggle to embed them into their QMS.
How to Avoid It: Develop a CSR process map, create a CSR register, integrate requirements into your system, train cross-functional teams, and conduct CSR-focused internal audits.
Kadmar Support: We help map CSRs to IATF clauses, define ownership, and ensure seamless implementation.
Why It Happens: Auditors lack training or treat audits as checklist exercises. Organization sees nonconformities as failures, not opportunities.
How to Avoid It: Train auditors to the IATF 16949 competency model, evaluate annually, and focus audits on continuous improvement.
Kadmar Support: We provide internal auditor training and full internal audit services to detect systemic issues early.
4. Poor Corrective Action Management
Why It Happens: Containment stops at surface fixes. Root cause analysis focuses on symptoms, not causes.
How to Avoid It: Apply 8D methodology, validate corrective actions, and analyze trends for repeat issues.
Kadmar Support: We design complaint-handling systems that prevent recurrence and enhance operational excellence.
Why It Happens: Risk analysis is treated as a checkbox instead of an improvement tool.
How to Avoid It: Use FMEA and control plans dynamically, update risk registers, and review risks in management meetings.
Kadmar’s Solution: We design risk matrices tailored to your operations.
6. Calibration and Equipment Control Gaps
Why It Happens: Calibration schedules and traceability are neglected, and equipment is used past due dates.
How to Avoid It: Maintain a master calibration list with alerts and retain all certificates.
Kadmar’s Solution: We help design calibration systems that prevent line stoppages.
7. Insufficient Supplier Performance Monitoring
Why It Happens: Suppliers aren’t regularly evaluated, and key metrics like PPM or OTD are missing.
How to Avoid It: Maintain supplier scorecards, conduct audits, and implement escalation protocols.
Kadmar Support: We improve supplier quality through our Supplier Excellence Program.
Why It Happens: Poor segregation and lack of MRB oversight cause repeat issues.
How to Avoid It: Label zones clearly, record every disposition, and involve MRB reviews.
Kadmar’s Solution: We establish effective NCR and rework control systems.
9. Lack of Evidence for Continual Improvement
Why It Happens: Certification is treated as paperwork rather than a performance tool.
How to Avoid It: Track KPIs, analyze trends, and tie improvements to objectives.
Kadmar’s Solution: We train and act as internal auditors to boost continual improvement culture.
10. Poor Management Review Process
Why It Happens: Reviews become routine and lack meaningful analysis.
How to Avoid It: Prepare structured review agendas with actions, owners, and deadlines. Include CSR performance, audits, and feedback.
