IATF 16949 Internal Audit Services for Automotive Suppliers

IATF 16949 Internal audits are not a checkbox—they’re the backbone of any robust quality system in the automotive industry. Under IATF 16949, organizations are expected to implement process-oriented internal audits that go far beyond standard ISO 9001 reviews. Our team supports Tier 1, Tier 2, and OEM-aligned suppliers in executing IATF 16949 internal audit services aligned with the latest IATF 16949 requirements and client-specific mandates.

What an IATF 16949 Internal Audit Covers

Our auditors conduct in-depth evaluations across all critical processes. Using a process approach aligned with clause 9.2 of the standard, we assess:

Process Effectiveness

Mapping of key value-adding processes, input/output relationships, KPI tracking, and Turtle Diagrams.

Risk-Based Thinking

Integration of FMEA results into daily operations, escalation management, and contingency planning.

Core Tool Application

Review of APQP, PPAP, SPC, MSA, and FMEA implementation and maintenance.

Audit Planning & Reporting

Evidence-based audit trail, cross-functional interviews, objective findings, and structured corrective actions.

Product & Process Conformity

Focus on traceability, change management, error-proofing, and special characteristics monitoring.

Customer-Specific Requirements (CSR)

Cross-verification of client-specific mandates within your system (e.g., VW Formel Q, Renault MMOG/LE).
