Anyone sourcing components from Asia for the automotive industry knows their OEM customer’s two favorite questions: “Are these parts IATF-compliant?” and “How did you verify that?” Anyone without a solid answer to both is out of the bidding process. Quality management in the automotive sector is therefore not a routine exercise of the audit department, but the lever that decides between a series contract and being passed over. At SGS Schach Global Solutions, quality management is a core process — not a downstream function. In this article, we show which standards we apply, how we put them into practice in our daily sourcing work, and what truly distinguishes a robust QM system in the automotive supply chain.

Why Quality Management in the Automotive Supply Industry Is in a League of Its Own

In few industries are quality requirements as codified and as measurable as in the automotive sector. A PPM rate (parts per million) above the single digits is not a matter for negotiation with a German OEM — it is grounds for disqualification. Behind that figure stands a tightly interconnected system of standards, processes, and audits that accompanies the entire lifecycle of a component — from design through sampling and into series production.

Three factors make automotive quality management particularly demanding: first, the high variant diversity combined with high volumes; second, just-in-time and just-in-sequence delivery, which leaves no buffer for rework; and third, legal product liability across the entire vehicle lifecycle. Anyone failing to systemically secure quality risks not just individual complaints, but recalls, contractual penalties, and lasting reputational damage.

The Core Standards — IATF 16949, VDA 6.3 and Beyond

Automotive quality management rests on a clearly defined foundation of standards. The most important building blocks we apply at SGS in every sourcing project:

IATF 16949 — The Global Automotive QMS Standard

IATF 16949 is the global quality management standard of the automotive industry and a requirement for every Tier-1 and Tier-2 supplier delivering directly to OEMs. Built on ISO 9001, it adds automotive-specific requirements such as risk management via FMEA, preventive defect avoidance, product safety officers, and defined response structures for non-conformities. When we qualify Asian suppliers, IATF certification is the first filter — anything without this certificate is immediately disqualified from the B-sample bidding process for German OEMs.

VDA 6.3 — The Process Audit of German OEMs

VDA 6.3 is a German industry standard issued by the Verband der Automobilindustrie (Association of the Automotive Industry) and defines a structured procedure for process audits at the supplier site. Unlike IATF certification, which evaluates the entire QM system, the VDA 6.3 audit goes specifically into individual production processes — tooling, injection molding, final assembly — and assesses process capability. With every supplier of ours in China, we conduct VDA-6.3-compliant audits on site before the first tool is released for production.

PPAP and PPF — The First-Article Inspection

PPAP (Production Part Approval Process) and PPF (Production Process and Product Approval per VDA 2) are the formalized procedures for first-article inspection. They typically include 18 documents — among them dimensional reports, material certificates, process FMEA, control plan, qualification records for machines and personnel, and capability studies (Cmk, Cpk). We coordinate the entire PPAP process for our customers and ensure that the first-article inspection passes on the first run — because every correction loop costs four to six weeks during the launch phase.

APQP — Quality Planning in the Development Phase

Advanced Product Quality Planning is the structured approach by which quality is built into the development phase from the start. APQP defines in five phases which quality measures take effect when — from concept through prototype and pre-series to series launch. Anyone applying APQP consistently avoids the costly last-minute corrections that typically appear during the sampling phase.

Quality Management with Chinese Suppliers — The Additional Hurdles

The standards are the same worldwide — the reality of their implementation is not. Anyone sourcing in China encounters several systemic challenges that a classic European QM approach does not cover:

Language and documentation gaps: Audit reports, dimensional records, and first-article documents often arrive in Chinese or in stilted English. Without a local translation and validation layer, an apparent compliance emerges that does not hold up in an actual complaint case.

Audit theater: Some suppliers display a showcase production during announced audits that doesn’t exist in daily operations. We therefore rely on unannounced follow-up audits and continuous spot checks — and not just on the one-time initial audit.

Switching sub-suppliers: A qualified manufacturer can swap its raw material or component suppliers within weeks without the end customer knowing. Our on-site presence catches such changes early, before they become a series problem.

Cultural complaint dynamics: “No problem” in Chinese business communication does not necessarily mean “everything is fine,” but often “we’ll deal with it later.” Without clearly documented escalation levels and hard delivery and quality KPIs, complaints fade into the background.

How We Implement Quality Management Operationally at SGS

Theory and standards alone do not produce quality — execution does. Our quality management in automotive sourcing rests on five operational building blocks:

1. Supplier qualification before tool release. Before a single cent flows into a tool, every new supplier passes a VDA-6.3-compliant process audit conducted by our team on site. We inspect machinery, tooling capability, workforce qualification, and the QM system. The results feed into an internal supplier rating.

2. Tool-build supervision in China. While the tool is being built, we are regularly on site. We check steel quality, tool design, and tooling concept — issues are resolved before they migrate into the sampling phase.

3. First-article inspection and PPAP coordination. We manage the full PPAP/PPF process — dimensional inspection with calibrated equipment, material verification, process capability studies, final approval documentation to the OEM customer.

4. Series support with hard KPIs. During ongoing series production, we monitor PPM rate, on-time delivery, complaint rate, and audit results. Quarterly reviews with each supplier keep the pressure constant — and surface weak signals early.

5. Escalation management on deviations. When something goes wrong, a defined staged plan kicks in: immediate action (8D report), root cause analysis with the supplier, containment action, mid-term corrective action, lessons learned in process and control plan. We are typically reachable for our customers within 48 hours — complaint cases are no exception to this rule.

Typical Mistakes in Automotive QM — and How to Avoid Them

From over fifteen years of sourcing experience, we repeatedly see the same failure patterns at companies that don’t structure their QM in the supply chain adequately:

Pure trust in supplier certificates. An IATF certificate on the wall does not mean the specific component process is mastered. Certificates are entry tickets, not guarantees.

Treating sampling as a mere formality. Anyone checking off the PPAP process as bureaucracy loses the most important early-warning system for series problems. Our experience: 80 percent of all later series complaints were already latently visible in the first-article inspection — if you look closely.

Audits without follow-up actions. An audit report in a binder without tracking of corrective actions is wasted time. Audits require consistent action management — otherwise the same findings repeat themselves over years.

Locating quality only at the supplier. Quality is also a shared responsibility on the customer’s side — at the OEM or Tier-1: specification clarity, tolerance definitions, change management. Weak specifications produce weak components, regardless of how good the supplier is.

Quality Management Automotive with SGS Schach Global Solutions

We take over the complete quality management along the sourcing chain for our customers — from initial supplier qualification through series support. Concretely, this means:

  • Supplier selection and on-site audits in China and Asia per VDA 6.3 and IATF standards
  • Tool-build supervision and process acceptance directly at the production site
  • First-article inspection, PPAP and PPF coordination through to OEM approval
  • Setup and operation of supplier scorecards with defined KPIs
  • Escalation management and 8D processing in complaint cases
  • Training and development of Asian suppliers to German quality standards

As an owner-managed company with our own location in China and a team that bridges cultural and linguistic gaps, we are the partner of choice when quality is not supposed to end in an audit report but to arrive on the line in flawless components.

Conclusion: Quality Management Is Risk Management — and a Sales Argument

Anyone working in the automotive supply industry without robust quality management loses twice: at contract awarding, because OEM audits aren’t passed, and in ongoing operations, because complaints, expedited shipments, and contractual penalties eat into the margin. Conversely, a professionally established QM system is one of the strongest sales arguments a Tier-2 supplier can have.

At SGS Schach Global Solutions, we don’t see quality management as an obligation but as a differentiator. Talk to us if you want to source components from China or Asia without compromising on quality — we’ll be glad to show you, in real, ongoing projects, how we make it work in practice.
