The publication of the new AIAG-VDA SPC Manual marks a significant milestone for the automotive industry. It is far more than an update of the previous AIAG guideline—it introduces a harmonized approach to Statistical Process Control that is expected to influence quality management systems, process monitoring, and future IATF 16949 and VDA 6.3 audits.
For many organizations, updating a manual will not be enough.
The real challenge is determining whether the current SPC system is aligned with the new philosophy, which places greater emphasis on process stability, the appropriate selection of control charts, integration with FMEA and Control Plans, and the use of SPC as a daily management tool rather than simply a capability calculation exercise.
Where Should You Start?
Based on our experience, the first step should not be rewriting procedures or changing software. Instead, organizations should perform a structured SPC Gap Analysis to assess the current system against the principles introduced by the new AIAG-VDA approach.
Typical assessment areas include:
- selection of process and product characteristics for statistical monitoring;
- suitability of control charts;
- process stability evaluation methods;
- capability and performance studies;
- treatment of non-normal data distributions;
- integration with APQP, FMEA, MSA and Control Plans;
- competency of engineers, quality personnel and process owners.
The objective is to identify strengths, highlight improvement opportunities, and establish a practical roadmap for compliance and operational excellence.

- Quality Managers;
- Production Supervisors;
- Internal Auditors;
- Process Owners and technical personnel involved in process monitoring.
Our training combines statistical fundamentals with real industrial case studies, enabling participants to understand not only how to apply the new AIAG-VDA methodology, but also why it represents a major step forward in managing process variation and improving operational performance.
The new AIAG-VDA SPC Manual should not be viewed simply as another compliance requirement. It offers organizations an opportunity to transform SPC into a proactive management system capable of reducing variability, preventing defects, supporting data-driven decisions, and strengthening customer confidence.
