Critical items should be fully verified before the audit is considered passed. This checklist is a prompt list, not a substitute for the standard or your certification body's rules. **Groups:** #### Clause 4 and 5: Context and leadership **Items:** **Text:** Scope of the QMS is documented and includes any remote support sites **Critical:** true **Text:** Customer specific requirements are identified and incorporated in the QMS **Critical:** true Quality policy is communicated and understood at all levels Process owners are assigned and organizational roles are defined Process effectiveness and efficiency are monitored with targets Management reviews include the required automotive inputs #### Clause 6: Planning **Items:** **Text:** Risk analysis includes lessons learned from product recalls, audits and returns **Critical:** true Preventive action process considers risk before problems occur **Text:** Contingency plans exist for key equipment, utilities and supply interruption **Critical:** true Contingency plans are tested periodically and reviewed Quality objectives are measurable and cascade to relevant functions #### Clause 7: Support **Items:** Infrastructure and plant layout support the process flow and prevent mix ups **Text:** Calibration records trace gauges to national standards and cover internal and external labs **Critical:** true **Text:** Measurement system analysis is completed for gauges named in the control plan **Critical:** true Internal laboratory scope is defined and technical procedures exist Internal auditors are competent per documented criteria Training records show awareness of product conformity and safety Documented information is controlled, including customer engineering specifications #### Clause 8: Operation **Items:** **Text:** Product approval process, such as PPAP, is followed for new and changed parts **Critical:** true **Text:** Control plans exist for each product and cover prototype, pre launch and production as needed **Critical:** true Control plans are updated after changes, complaints and process failures PFMEA and control plan reflect special characteristics consistently **Text:** Supplier selection, monitoring and development follow documented criteria **Critical:** true Change management for processes is controlled and verified before production Operator work instructions and set up verification are available at the station Total productive maintenance and tooling management are planned Identification and traceability meet customer and regulatory needs **Text:** Control of nonconforming product prevents unintended use and shipment **Critical:** true Rework and repair follow approved instructions and are reinspected #### Clause 9: Performance evaluation **Items:** **Text:** Internal audit programme covers QMS, manufacturing process and product audits **Critical:** true Manufacturing process audits cover all shifts at suitable frequencies Product audits verify conformity at defined stages against requirements Customer scorecards and complaints are tracked and acted on Management review is held at planned intervals with records of decisions #### Clause 10: Improvement **Items:** **Text:** Problem solving uses a defined method, with root cause evidence **Critical:** true Error proofing is considered in corrective action and tested for effectiveness Warranty management and field failure analysis processes are in place Corrective actions are verified as effective before closure Continual improvement actions address the process, not just the incident ## Content **Intro:** IATF 16949 internal audits must cover the QMS, each manufacturing process and the product over a planned programme. This checklist gives auditors a clause by clause prompt list, with critical items flagged so evidence is verified first. **Sections:** #### How to use the checklist **Body:** Pick the process or area you are auditing, then work through the groups that apply. For each item, sample records and ask the process owner to show evidence, rather than accepting a verbal answer. Tick items verified, leave gaps unticked and record findings in your audit report. The checklist is organized by clause, but the programme should follow processes, so combine clause groups when you audit one area end to end. #### Three kinds of audit **Body:** IATF 16949 expects QMS audits, manufacturing process audits and product audits. A QMS audit tests the whole system against the standard and customer requirements. A manufacturing process audit tests whether the process is controlled as the control plan, work instructions and PFMEA describe, on all shifts. A product audit checks finished product against specifications at suitable stages. Use this checklist mainly for the QMS audit and adapt items for the other two. **Bullets:** - QMS audit: whole system against the standard - Process audit: control plan and instructions on the floor - Product audit: product against requirements - Cover all shifts and all customer specific requirements #### Reading your score **Body:** A high tick rate does not mean readiness if critical items are open. Treat every unticked critical item as a likely nonconformity and plan corrective action with owners and dates. Items you could not verify count as gaps, because a certification auditor will ask for the same evidence. Re-audit gaps and keep records of the previous cycle so you can show closure. #### Common mistakes **Body:** Auditing only to the standard and missing customer specific requirements, auditing a single shift, using auditors who audit their own work, and writing findings as vague observations with no objective evidence. Update the programme using customer complaints and risk, not only a fixed calendar. **Cta:** If audit evidence is spread across ERP, MES and quality systems, Netray can discuss a private assistant that pulls the records for an auditor. **Faq:** #### How often must IATF 16949 internal audits be done? **Answer:** The programme must cover the whole QMS, all manufacturing processes and products, based on risk, performance and past audit results. A full cycle each year is common for QMS audits, but process audits run more often where risk is higher. Your certification body checks the programme logic. #### Who can be an internal auditor? **Answer:** Internal auditors must be competent under documented criteria, which include knowledge of the standard, customer specific requirements, core tools and auditing skills. They should be independent of the area audited, which usually means someone outside that process. #### What are the core tools in IATF 16949? **Answer:** The core tools are APQP, PPAP, FMEA, MSA and SPC. Auditors should check that the organization applies them correctly and that their outputs, such as control plans and capability studies, stay consistent with each other. #### Does this checklist replace the standard? **Answer:** No. It is a prompt list organized by clause and does not reproduce the standard. Always audit against the current published IATF 16949 text, the applicable sanctioned interpretations and the customer specific requirements for your site. ## Search terms iatf 16949 internal audit checklist, iatf 16949 audit checklist excel, iatf 16949 checklist pdf, iatf 16949 clauses checklist, iatf internal audit template, iatf 16949 manufacturing process audit, automotive qms audit checklist, iatf 16949 requirements list --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
