Audit Techniques & Development
An audit is only useful if the auditor knows what to look for and how to listen. ISS develops your internal audit capability against the standards your customers actually demand - VDA, IATF 16949, ISO 9001 - and the tools that make audits effective: FMEA, Reverse FMEA, Poka Yoke verification, and control plan auditing.

When this applies

How we deliver
Methodology
We train auditors using your actual processes as the case study. Sessions include observation drills, role-play interviews, and finding-writing workshops. By the end, each participant has conducted at least one full audit with peer review. We can also provide certified lead auditor mentoring under VDA and IATF schemes if your organization is moving toward independent audit capability.
