What is IATF 16949? A Global Standard for Automotive Quality
IATF 16949 is the definitive international standard for automotive quality management systems. Published by the International Automotive Task Force (IATF), a group comprised of major automotive manufacturers (including BMW Group, Daimler AG, Ford Motor Company, General Motors, Stellantis, Renault Group, Volkswagen AG, and their respective trade associations), it was developed to harmonize the various regional and national automotive quality system requirements.
The standard was first introduced in 1999 as ISO/TS 16949, building upon the widely recognized ISO 9001 standard for quality management. In October 2016, it was revised and renamed IATF 16949:2016, replacing its predecessor. Crucially, IATF 16949 is not a standalone QMS. It must be implemented in conjunction with and is supplemental to ISO 9001:2015. This means that an organization must not only comply with all requirements of IATF 16949 but also with all requirements of ISO 9001:2015.
The Genesis and Evolution of IATF 16949
- Provide a common QMS approach for the automotive industry.
- Reduce the need for multiple certifications.
- Improve the quality and integrity of automotive components and services.

- Gap Analysis: Conduct a thorough assessment of the existing QMS against the requirements of IATF 16949 and ISO 9001:2015. This identifies areas of non-conformance and defines the scope of work required.
- Documentation Development: Based on the gap analysis, develop or update the QMS documentation, including a quality manual (if chosen), procedures, work instructions, forms, and records. This ensures all processes are clearly defined, controlled, and consistently followed.
Phase 2: Implementation and Internal Audits
Once the QMS is designed, it must be put into practice and its effectiveness verified.
- QMS Implementation: Roll out the documented processes across all relevant functions and levels of the organization. This involves operationalizing procedures, collecting data, and ensuring that employees are following the new system.
- Internal Audits: Conduct a series of internal audits by trained personnel. These audits objectively assess the conformance of the QMS to IATF 16949, ISO 9001, and the organization’s own documented procedures. They identify non-conformities and opportunities for improvement.
- Management Review: Top management reviews the performance of the QMS at planned intervals. This includes reviewing internal audit results, customer feedback, process performance, nonconformities, and the status of corrective actions to ensure continued suitability, adequacy, and effectiveness.
- Corrective Actions: Address all identified non-conformities from internal audits and management reviews by implementing effective corrective actions to eliminate the root causes and prevent recurrence.
Phase 3: External Certification Audit
This phase involves engaging an IATF-recognized certification body to independently assess the QMS.
- Select a Certification Body: Choose an IATF-recognized certification body (CB). The CB will guide the organization through the audit process.
- Stage 1 Audit (Readiness Review): The CB conducts an off-site or on-site review of the organization’s QMS documentation to determine its readiness for the Stage 2 audit. This includes verifying that the scope of certification is appropriate, the QMS addresses all IATF 16949 and ISO 9001 requirements, and internal audits and management reviews have been conducted.
- Stage 2 Audit (Main Audit): This is a comprehensive on-site audit where the CB auditors evaluate the implementation and effectiveness of the QMS. They will interview employees, review records, observe processes, and assess conformance to the standard and the organization’s own procedures.
- Non-conformity Resolution: If any non-conformities (major or minor) are identified during the Stage 2 audit, the organization must develop and implement corrective action plans within strict deadlines (typically 90 days for major non-conformities, 60 days for minors, with 90-day closure required).
- Certification Decision: Once all non-conformities are effectively closed and verified by the CB, the certification body will make a positive recommendation, and the IATF 16949 certificate is issued.
The entire process, from initial planning to certification, can take anywhere from 9 to 18 months, depending on the organization’s size, complexity, existing QMS maturity, and dedicated resources.
