How to use the checklist
- Plan: choose the processes and clauses for this audit from your audit programme. Remove questions that are out of scope with “Edit checklist”.
- Collect evidence: records, documents, interviews and observation. Note what you saw in the evidence field, for example “training records of 12 operators”.
- Rate: Conform, OFI, minor or major nonconformity, or N/A.
- Write the finding as requirement, evidence and gap, so the auditee can act on it.
- Agree actions with owners and dates and close them after checking effectiveness. Use an 8D report or A3 for the larger ones.
Writing a good nonconformity
A clear finding has three parts: the requirement (clause or internal procedure), the evidence (what was seen, with references) and the gap (why it does not meet the requirement). Avoid opinions and avoid naming people.
For automotive suppliers, use the IATF 16949 checklist in addition, and the VDA 6.3 process audit for the manufacturing process itself.
Frequently asked questions
›What is the difference between a minor and a major nonconformity?
A major nonconformity is the absence or total breakdown of a required process, or a situation that raises serious doubt that the system can deliver conforming product. A minor nonconformity is a single lapse or partial failure that does not put the system at risk. Many minors on the same requirement can add up to a major.
›What is an opportunity for improvement (OFI)?
An observation where the requirement is met, but the auditor sees a way to make the process more effective. It needs no corrective action, but it is worth recording.
›Is this checklist the text of ISO 9001?
No. The questions are our own short wording, organised by the clauses 4 to 10 of ISO 9001:2015. Use them as audit prompts together with the standard, which you need to buy from ISO or your national standards body.
›How is the conformity percentage calculated?
Conform and OFI count as 100 %, a minor nonconformity as 50 % and a major as 0 %, averaged over the rated questions. N/A is left out. The percentage is only a summary, the certification decision depends on the findings, not on a score.
›How often must internal audits be done?
ISO 9001 clause 9.2 asks for audits at planned intervals, based on the importance of the processes, changes and previous results. Most companies cover every process at least once a year.
