System audits, process audits, and product audits examine quality conformance at three different levels. A system audit evaluates the quality management system as a whole — confirming that the organization has implemented all required QMS elements (quality policy, management review, documented information, competence management, internal audit, corrective action) against the applicable standard (IATF 16949, AS9100, ISO 9001). A process audit evaluates a specific production or support process — following the process through its steps, confirming that each step is controlled, measured, and capable of producing conforming output consistently. The VDA 6.3 audit is a structured process audit. A product audit evaluates a specific product against its design and quality requirements — confirming that a sample of production output conforms to all applicable specifications. Effective quality management audit programs use all three levels, allocating emphasis based on the quality risk profile of the organization.
The EMUG AUDIT Framework is EMUG’s five-phase process and quality audit methodology, standing for: Audit scope plan, Understand current state, Data and evidence collect, Investigate non-conformances, and Track closure. It produces better corrective actions through two structural features. In the Investigate phase, EMUG requires that every major non-conformance finding includes a root cause analysis identifying the systemic failure that produced the finding — not just a description of the symptom observed. This forces corrective actions to address the root cause. In the Track Closure phase, EMUG assesses proposed corrective actions against the root cause before they are approved, and verifies corrective action effectiveness before formally closing the finding — preventing the closure of corrective actions that have been implemented but not verified to actually prevent recurrence.
VDA 6.3 is the process audit standard published by the German Association of the Automotive Industry (VDA) — used by German automotive OEMs (BMW, Mercedes-Benz, Volkswagen Group, Audi, Porsche) and their global supply chains for structured assessment of production and logistics process quality. VDA 6.3 uses a structured question catalogue organized into seven process elements: P1 (Potential analysis for new suppliers), P2 (Project management), P3 (Planning of product and process development), P4 (Supplier management), P5 (Incoming goods and storage), P6 (Production process and product analysis), and P7 (Customer care and customer satisfaction). Each element is scored on a percentage scale; suppliers must achieve 90 percent or above in P6 for production process approval. German OEMs require VDA 6.3 audits because the structured process-level assessment provides more detailed quality risk information than an ISO 9001 system audit for manufacturing suppliers.
EMUG’s IATF 16949 certification preparation approach uses three sequential activities in the 6 to 12 months before the certification audit. Gap assessment: a complete audit of the organization’s QMS against all IATF 16949:2016 clauses and applicable customer-specific requirements, identifying every major and minor non-conformance. This assessment is structured to replicate the third-party certification body’s approach — using the same audit questions, evidence standards, and grading criteria that a certification body auditor applies. Corrective action support: for each major non-conformance identified, EMUG facilitates root cause analysis and supports corrective action development, ensuring that proposed actions address the systemic root cause. Pre-audit verification: a follow-up assessment 4 to 6 weeks before the certification audit confirming that corrective actions have been implemented and are effective. Programs prepared using this three-phase approach achieve zero major findings at certification audits in 90 percent of cases.
EMUG conducts supplier quality audits across 20 countries using a combination of EMUG-employed auditors in key markets (India, Germany, UK, UAE, China) and a network of qualified supplier development audit partners for markets with lower audit frequency. All auditors follow EMUG’s standard audit methodology (EMUG AUDIT Framework) and use consistent findings grading criteria, corrective action requirement formats, and audit report structures — ensuring that a supplier audit report from EMUG in South Korea is directly comparable to one from Germany or Mexico. For automotive customers requiring VDA-certified VDA 6.3 auditors, EMUG uses VDA QMC-certified auditors for all VDA 6.3 supplier audit programs. Remote audit capabilities for initial document review phases, with on-site execution for process walkthrough and evidence collection.
NADCAP (National Aerospace and Defense Contractors Accreditation Program) is an industry-managed special process accreditation program administered by the Performance Review Institute (PRI) — required by major aerospace OEMs (Boeing, Airbus, Lockheed Martin, Raytheon) for suppliers performing special processes including heat treatment, non-destructive testing (NDT), chemical processing, welding, and composites manufacturing. NADCAP approval requires a structured audit against NADCAP audit criteria (AC7110 for NDT, AC7102 for heat treatment, AC7004 for welding) performed by a NADCAP-approved auditor. EMUG supports NADCAP approval preparation by conducting pre-NADCAP gap assessments against the applicable audit criteria, identifying non-conformances and supporting corrective action development before the formal NADCAP audit, and coaching process engineers and quality teams on the specific evidence and documentation requirements of each NADCAP audit criteria set.
Corrective action effectiveness verification is the step most frequently skipped in audit programs — and its absence is the reason the same findings recur across successive audits. EMUG verifies corrective action effectiveness through two mechanisms. Documentary verification: reviewing the corrective action implementation evidence (updated procedure, training records, process change documentation) to confirm that the corrective action has been implemented as planned. Objective effectiveness measurement: confirming that the quality metric affected by the non-conformance has improved to an acceptable level — for example, a corrective action addressing inadequate incoming inspection is verified effective by confirming that the non-conformance rate for incoming inspection has declined to within the target range after the new inspection process has been operational for 60 to 90 days. A corrective action is only formally closed in EMUG’s tracking system when both documentary implementation and objective effectiveness measurement are confirmed.
EMUG delivers process and quality audit services to automotive OEMs and Tier 1 suppliers (IATF 16949, VDA 6.3, customer-specific requirements), aerospace and defense organizations (AS9100 Rev D, NADCAP, AS9102 FAI), industrial machinery manufacturers (ISO 9001, EN 13849, ATEX), energy and oil and gas companies (ISO 55001, API Q1, API Q2, ISO 9001), and engineering services and EPC firms. Delivery countries include Germany, France, UK, Netherlands, Sweden, Italy, Spain, Poland, Czech Republic, UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, India, China, Japan, South Korea, Malaysia, Thailand, USA, Canada, Mexico, Brazil, South Africa, Nigeria, and Kenya.
