Preparing for an ISO 9001 audit comes down to four things: keeping documented information under control, showing your processes run the way you say they do, closing open nonconformities, and rehearsing through an internal audit. This step-by-step guide works through each stage in the order a certified manufacturer should tackle it, from the 90-day countdown to the day itself. It covers surveillance and recertification audits, what auditors actually check on a manufacturing floor, the most common nonconformities and how to close them, and what changes under ISO 9001:2026. A free downloadable checklist turns it into something your team can work through, clause by clause.
