Audits and Compliance
Audits are where the gap between what your QMS says and what your team actually does becomes painfully visible. Whether the auditor is IATF, AS9100, ISO 9001, VDA 6.3, or a customer second party team, the rituals look similar, the findings look similar, and the prep work is rarely as ready as anyone claims. The guides in this topic cover the practical checklists, the clauses most commonly missed, and how to keep an audit ready posture without dedicating a person full time to staring at the document control system. Written for engineers who would rather pass an audit than perform one.
