IATF 16949
What the automotive quality standard adds on top of ISO 9001, which records a third-party auditor samples, and which of them get kept as the job runs.
IATF 16949 is the automotive quality management standard published by the International Automotive Task Force. It is not standalone: it is applied together with ISO 9001 and adds automotive requirements for defect prevention, control plans, the core tools, product safety, embedded software and supplier development. Each OEM then flows down its own customer-specific requirements.
ISO 9001 extended with automotive requirements for defect prevention, control plans, production part approval, and supply chain management.
International Automotive Task Force
Sites that manufacture production parts, service parts or accessory parts for the automotive industry. A site must have manufacturing to be certified, which excludes a pure design office or a distributor; those get covered as remote supporting functions of a certified site instead. IATF 16949:2016 is the current edition.
Certification is by a certification body recognised by an IATF oversight office, under the IATF Rules rather than general accreditation rules. The Rules set the audit day calculation, mandate performance data before the initial audit, and allow a certificate to be withdrawn for a major nonconformity that is not closed inside the stated window.
Organizations in the automotive supply chain that manufacture production parts, service parts, or accessory parts.
| Requirement | Module | What It Does |
|---|---|---|
| Clause 8.5.2.1 traceability and reaction plan | Inventory | The automotive clause goes further than ISO 9001: the traceability process has to let you contain suspect material at a defined point and identify the first and last part affected. Receiving records the lot and its certificate, every issue to a job preserves the link, and completions assign serials, so the forward and backward genealogy exists as a query. The reaction plan, the customer notification and the sort decision remain your process, written and owned by your quality group. |
| Control plan verification at the operation | Quality | Annex A makes the control plan a required output, listing each product and process characteristic, its specification, the evaluation method, the sample size and frequency, and the reaction plan. WorkCell holds inspection templates and AQL sampling plans that carry the characteristics, the specification, the evaluation method and the frequency the control plan designates, and records the results against the operation. Because the template and the result sit on the same revision of the part, an auditor comparing a current plan against the recorded frequency is reading one source rather than reconciling two. |
| Clause 8.7 control of nonconforming product | Quality | Severity-classified nonconformances record the defect, the quantity, the disposition and who decided, attached to the job and lot that produced it. Automotive adds rules for reworked and repaired product and for customer waivers, and it requires suspect product to be treated as nonconforming. The record carries the disposition and the quantity; the deviation authorisation from the customer, and the instruction the rework was performed to, come from your own documents. |
| Problem solving and error-proofing evidence | Quality | Clause 10.2.3 wants a defined problem-solving approach with containment, root cause, implemented corrective action and verification of effectiveness. 8-D records carry that chain off the originating defect, with the dates that show how long containment took. Error-proofing verification and layered process audits are separate automotive requirements, and the challenge-part check lands as an inspection step on the routing with its own recorded result, so the verification evidence is a transaction rather than a tick on a clipboard. |
| Clause 7.5.3.2.1 record retention | Engineering | Automotive record retention is longer than most shops expect: production part approvals, tooling records, and product and process design records are kept for a period tied to how long the part stays active for production and service, and each customer can require longer. Versioned and effective-dated bills of material and routings mean a job closed years ago still reports the structure it was built to. Document retention policy and the archive of the PPAP package itself remain yours to run. |
| Clause 8.4 supplier management | Purchasing | A supplier catalog holds what each vendor is approved to provide, purchase orders are written against it, and receipts tie back to the lot and certificate. Automotive then demands supplier QMS development toward certification, second-party audits, and monitored performance against delivered quality and disruptions. Receipt and nonconformance history is the raw data a scorecard runs on, and because every receipt and every defect carries its vendor, delivered quality and disruption counts come from live records and move out through the REST API into whatever scorecard your customer wants to see. |
The auditor picks a shipped part and asks for the material lot, the certificate, the jobs it passed through, the operations and operators, the inspection results, and the first and last serial in that run. In WorkCell that chain resolves from the genealogy. Where the trail leaves the system, usually into the control plan or the PPAP file, expect the auditor to follow it there.
Every characteristic the control plan designates gets checked at the stated frequency and sample size, and the auditor compares the plan against what was actually recorded. Inspection templates and AQL plans hold the sampling basis and the operator entry holds the result. Where the plan calls for variable data and a control chart, the measured values are captured against the characteristic at the operation, so the chart and the capability study behind it are built from recorded readings rather than from a separate log.
Clause 4.4.1.2 requires documented processes for product-safety-related parts, including special approvals of process documentation, traceability by lot, and training for the people involved. WorkCell holds the lot traceability and the transaction attribution, the safety designation on the item it applies to, the special approvals attached to the process documentation, and the people cleared to run each operation on the workforce record, which is the three things an auditor asks to see together.
Customer complaints, warranty returns and internal escapes get sampled, and the auditor tests whether the problem-solving record shows containment dates, a root cause that explains the escape as well as the defect, and verification that it worked. 8-D records attached to the originating nonconformance carry it. Recurrence on a verified action is the finding they are hunting for.
Each OEM publishes its own requirements on top of the standard, and the audit covers them. Nothing in WorkCell interprets a customer-specific requirement, and no vendor should claim to. Expect to maintain a matrix mapping each customer's requirements to where you satisfy them, and expect WorkCell to be one of several systems named in that matrix.
Can you be certified to IATF 16949 without ISO 9001?
No. IATF 16949 is written as a supplement and cannot be used on its own; the ISO 9001 requirements apply in full underneath it. A single audit covers both, and the certificate names IATF 16949. You do not need a separate ISO 9001 certificate alongside it.
Can software make us IATF 16949 compliant?
No software confers certification. An IATF-recognised certification body audits your site against the standard, the core tools and each customer's requirements, and the IATF Rules govern the outcome. A system holds evidence an auditor samples. The certificate, the audit and the programme belong to your organization.
What are the automotive core tools?
Five reference manuals the standard leans on: APQP for development planning, PPAP for part approval, FMEA for failure mode analysis, MSA for measurement system analysis, and SPC for statistical process control. WorkCell authors none of them. It records the inspection results, scrap and nonconformances the tools are meant to govern.
Does WorkCell do control plans, PFMEA, MSA or SPC?
WorkCell holds the inspection templates and AQL sampling plans that carry the characteristics, specifications, methods and frequencies a control plan designates, records the results against the operation with the gage and the inspector named, and raises severity-classified nonconformances with 8-D corrective action off them. That is both the planning basis an auditor reads and the conformance evidence they compare it against, on the same revision of the part.
How long do we have to keep automotive records?
Longer than most shops plan for. Production part approvals, tooling records, and product and process design records are retained for a period tied to how long the part remains active for production and service requirements, and each OEM's customer-specific requirements can extend it. Effective-dated versions in WorkCell keep the as-built structure retrievable.
