IATF 16949:2016 Internal Audit — Supplemental Requirements

Goal

Audit the automotive-specific supplemental requirements of IATF 16949:2016, including CSR compliance and the three mandatory internal audit streams. Use in conjunction with iso-9001-internal-audit for a complete IATF audit.

When to use

This skill covers the IATF 16949 supplemental requirements — the automotive additions to ISO 9001.

IATF 16949 requires three types of internal audit (§9.2.2.1). All three must be planned, executed, and recorded within the audit programme cycle:

1. QMS audit — covers the entire quality management system (ISO 9001 + IATF supplementals)
2. Manufacturing process audit — process-based, covers all manufacturing processes at least annually
3. Product audit — product-specific, verifies product conformance to specifications

All manufacturing processes must be audited at least annually, with increased frequency for high-risk or poor-performing areas.
