VDA 6.3 Audit Process: Comprehensive Guide for Cost and Management Accountants
Explore the VDA audit process with detailed steps, sample audit plans, case studies, and reports. This guide provides comprehensive insights for CMAs to understand and apply VDA auditing standards effectively.
Introduction to the VDA Audit Process
The VDA audit is an essential process for assessing and improving quality management systems in manufacturing, particularly in the automotive industry. Originating from the Verband der Automobilindustrie (VDA), the audit system is designed to evaluate process quality throughout production, ensuring that suppliers meet stringent quality requirements from German automakers like Volkswagen, BMW, and Mercedes-Benz.
For Cost and Management Accountants (CMAs), the VDA audit offers valuable insights into cost control, resource allocation, and continuous improvement. This article provides a detailed breakdown of the VDA audit process, practical examples, and tips on how CMAs can support the audit process to maximize organizational value.
What is the VDA Audit?
The VDA 6.3 audit is designed to assess and improve manufacturing processes by evaluating the quality management system. It's based on the VDA 6.3 standard, which focuses on process elements that span from product development to supplier management and risk control.
Purpose of the VDA Audit
- Ensure compliance with quality standards and customer expectations
- Identify areas of improvement in the production process
- Evaluate supplier quality systems and their impact on overall product quality
- Optimize resources by detecting inefficiencies and waste
- Maintain customer satisfaction through proactive management of defects and complaints
Who Needs to Perform a VDA Audit?
The VDA audit is crucial for organizations within the automotive supply chain. Companies that need to perform the VDA audit include:
- OEMs (Original Equipment Manufacturers)
- Tier 1 suppliers (primary component manufacturers)
- Tier 2 suppliers (secondary suppliers providing components to Tier 1)
- Tooling and contract manufacturers
- Service providers involved in the automotive production process
Key Elements of the VDA 6.3 Standard
The VDA 6.3 standard covers seven process elements (P1 to P7), each focusing on different aspects of quality management. The audit evaluates whether these processes are effectively managed and if the organization is ready to meet customer quality requirements.
P1: Project Management
- Objective: Evaluates the management of resources, scheduling, and responsibility during project planning.
- Focus Areas: Project timelines, resource allocation, responsibility assignments, risk management.
P2: Product and Process Development (Product Side)
- Objective: Examines how product requirements are defined and adhered to throughout development.
- Focus Areas: Design specifications, FMEA (Failure Mode and Effects Analysis), and product validation.
P3: Product and Process Development (Process Side)
- Objective: Focuses on how production and assembly processes are developed and controlled.
- Focus Areas: Process capability, cycle time reduction, and error-proofing systems (e.g., poka-yoke).
P4: Supplier Management
- Objective: Assesses how suppliers are selected, integrated, and monitored for compliance.
- Focus Areas: Supplier qualifications, supplier relationship management, performance tracking.
P5: Process Analysis – Serial Production
- Objective: Evaluates the efficiency and quality of the serial production process.
- Focus Areas: Quality control, waste reduction, process optimization, machine setup, and operator skills.
P6: Customer Satisfaction/Customer Service
- Objective: Assesses how well the company handles customer feedback, complaints, and warranty claims.
- Focus Areas: Customer feedback mechanisms, complaint resolution, and service level performance.
P7: Risk Management and Control
- Objective: Evaluates the company’s risk management strategies to avoid quality failures.
- Focus Areas: Risk identification, risk mitigation, preventive measures, and contingency planning.
Step-by-Step VDA Audit Process: An In-Depth Guide
The VDA audit is a multi-step process that involves careful planning, data collection, observation, and evaluation. Here’s a detailed breakdown:
1. Audit Planning and Preparation
Before the audit commences, thorough planning is essential for a smooth audit process:
- Select qualified auditors who are VDA-certified
- Define the audit scope to include relevant processes and areas
- Prepare audit documentation: This includes historical data, process records, performance reports, and supplier information
- Set up an audit schedule and ensure key stakeholders are informed and ready
2. Opening Meeting
During the opening meeting, the following tasks are completed:
- Introduction of the audit team and their roles
- Briefing on the audit objectives, scope, and methodology
- Overview of the company’s organizational structure and quality policies
3. Document Review and Initial Assessment
Auditors examine key documents such as:
- Quality manuals and process flow diagrams
- Control plans and FMEA reports
- Training records and supplier performance data
- Previous audit reports (if applicable)
This review helps auditors understand the systems in place and identify areas of concern for further investigation.
4. On-Site Process Observation
On-site audits involve visiting production areas and assessing:
- Process workflows
- Machine settings and calibrations
- Employee competence and adherence to SOPs (Standard Operating Procedures)
- Quality control measures at various stages of production
5. Employee Interviews
Auditors conduct interviews with employees to:
- Verify understanding of quality standards
- Assess training levels and job-specific competencies
- Gauge employee engagement with quality improvement initiatives
6. Scoring and Evaluation
Auditors evaluate compliance based on the following ratings:
- A (Full Compliance)
- B (Minor Deviation)
- C (Major Deviation)
Each process element is rated, and the total audit score helps categorize the company’s quality management capabilities.

Case Studies: VDA Audits in Action
Case Study 1: Automotive Component Manufacturer
A Tier 1 supplier to Volkswagen underwent a VDA 6.3 audit. The audit revealed high scrap rates due to poor machine calibration, leading to production delays and increased costs. The company implemented automated calibration systems and provided additional operator training. As a result, scrap rates reduced by 15%, and production efficiency improved by 10% within six months.
Case Study 2: Electronics Supplier to BMW
An electronics supplier to BMW was audited under VDA 6.3. The audit highlighted a lack of communication between the design and production teams, causing delays in product launches. By introducing regular cross-functional team meetings and better documentation practices, the supplier improved its delivery time by 20% and received a higher VDA audit rating in the next review.
Conclusion: VDA Audit as a Tool for Continuous Improvement
The VDA audit process is a comprehensive system that ensures organizations stay competitive by adhering to strict quality standards. For Cost and Management Accountants (CMAs), the VDA audit process provides critical insights into resource optimization, process efficiency, and cost control.
By participating actively in the audit, CMAs can contribute to the identification of cost-saving opportunities and help align quality practices with organizational goals.
