An IATF 16949 internal audit is not a document review. Auditors are verifying that a quality management system actually operates the way it says it does, across every applicable clause, over the course of an audit cycle, not just on the day someone is watching.
Auditors follow a process as it runs: manufacturing audits cover every shift, including evidence that a proper shift handover happens, not only the shift the audit happened to land on.
APQP outputs, FMEAs and control plans are checked for whether they are live working documents, updated as the process changes, rather than artefacts produced once for a customer submission and left untouched.
IATF 16949 expects internal auditors who audit the Core Tools to be competent in them. An auditor who cannot follow an FMEA cannot meaningfully verify one.
Findings are graded, tracked to closure, and reviewed for patterns. A cluster of minor findings in the same area is treated differently to isolated ones, because it points to a systemic issue rather than a one-off.
A checklist tells an auditor what to look at. It does not teach them how to judge whether an FMEA is genuinely live, or whether a control plan reflects what actually happens on the line. That judgment comes from training, and it is exactly where a document or a single classroom session struggles to transfer understanding consistently across a supply chain.
We build the video training that turns audit competence from something a few senior people carry in their heads into something a whole team can learn consistently. The Quality Partner training portal we built productised thirty years of Paul Hardiman's auditing expertise, the "Auditor of Auditors" recognised by the IATF, into 500+ video lessons covering exactly this kind of practical audit judgment. Our production runs on a BSI ISO 9001 certified process (FS 763439), so the accuracy holds as it scales.
