Stage 2 audit

The full certification assessment — an auditor examines whether your management system is genuinely implemented and effective, not just documented. The audit that determines whether you get the certificate.

Stage 2 is the main certification audit. Where Stage 1 asked whether you are ready, Stage 2 asks whether the system actually works.

What happens

The auditor gathers objective evidence that your management system is implemented and effective: interviewing people at all levels, observing activities, sampling records, tracing processes end to end, and checking that what your procedures describe is what actually happens.

Expect them to follow threads. A single order might be traced from enquiry through requirement review, planning, purchasing, production, inspection, release and delivery — and any of those steps can surface a finding.

The outcome

  • No nonconformities — recommendation for certification
  • Minor nonconformities — usually recommendation subject to an accepted corrective action plan, verified at surveillance or by document review
  • Major nonconformities — certification withheld until closed and verified, sometimes requiring a further on-site visit

The auditor recommends; the certification body’s independent review makes the decision.

The most common surprise

Systems fail Stage 2 far more often on change than on their initial build. Supplier re-evaluation that never happened, production changes made without documented review, requirements that changed after the original review, post-delivery problems handled informally as customer service and never entering the system. The first pass through everything tends to be well documented; what happens afterwards is where the evidence thins.
