What is a passing score for VDA 6.3?

Scores above 90% typically result in a grade A, 80-90% in grade B, and below 80% in grade C. OEM requirements vary, but A or B is usually required.

Which process elements are most critical in VDA 6.3?

P6 (Production) is heavily weighted because it reflects real manufacturing performance. P2-P4 cover project management and product development controls.

How long does VDA 6.3 preparation take?

Preparation typically takes 4-12 weeks depending on gap severity, audit scope, and data availability.

Is VDA 6.3 required for all automotive suppliers?

Not always, but many German OEMs and Tier-1s require it. It is often used for supplier qualification and requalification.

How does VDA 6.3 relate to IATF 16949?

IATF 16949 defines a quality management system, while VDA 6.3 audits how effectively processes are executed. Both are complementary and often required by the same customers.

Definition

VDA 6.3 Process Audit(VDA 6.3)

VDA 6.3 is a process audit standard used in the automotive industry to evaluate product and process quality across the supply chain. It assesses process capability, risk, and compliance using structured questionnaires and scoring.

What is VDA 6.3 Process Audit?

VDA 6.3 is a German automotive process audit standard focused on how well manufacturing and supplier processes are designed and controlled. It evaluates process elements across product realization, production, and customer support.

Audits produce a score and a classification (A, B, or C) that indicates process maturity and risk. OEMs often require suppliers to pass VDA 6.3 audits for program approval or ongoing business.

Key Points

VDA 6.3 audits evaluate process capability, not just documentation
Scoring uses process element ratings and a weighted overall result
Findings focus on risk to customer requirements and product conformity
Preparation includes process mapping, evidence collection, and gap closure
Audit results influence supplier status and sourcing decisions

Implementation Guide

Steps:

1Define audit scope and applicable process elements (P2-P7)
2Collect evidence for each question (procedures, records, KPIs)
3Perform a self-assessment with scoring and gap list
4Prioritize gaps by risk and customer impact
5Implement corrective actions and verify closure
6Conduct a readiness review or mock audit
7Complete the formal audit and address any findings

Best Practices:

Use cross-functional teams to gather evidence and validate process reality
Focus on process effectiveness, not just document completeness
Track findings by process element to reveal systemic weaknesses
Prepare objective metrics for P6 (production) questions
Align audit preparation with PFMEA and Control Plan updates

Common Mistakes to Avoid

• Relying on documentation without evidence of process execution
• Underestimating P6 and P7 process performance questions
• Treating the audit as a one-time event instead of a system check
• Ignoring supplier and customer interface requirements
• Missing linkage between audit findings and PFMEA updates
