AIAG & VDA SPC Manual

Overview

The AIAG & VDA SPC Manual establishes a harmonized approach to Statistical Process Control (SPC), developed jointly by AIAG and the German Association of the Automotive Industry (VDA) to drive greater consistency throughout the global automotive supply chain. 

Designed for today's manufacturing environments, the standardized manual translates statistical concepts into a practical implementation framework that supports SPC deployment, launch and production readiness, APQP and PPAP activities, and a stronger connection between process knowledge, statistical analysis, and Control Plan execution.

Key features and benefits include:

• Harmonized AIAG & VDA methodology that supports consistent SPC application across the global automotive supply chain
• Control-loop framework that connects SPC activity to real-time monitoring, retrospective analysis, and product, process, and system-level review
• Expanded guidance for selecting control charts and evaluating non-normal data based on process characteristics, data type, and monitoring objectives
• Structured guidance for machine capability, preliminary process performance, and ongoing process capability studies, including appropriate application and interpretation of capability indices
• Time-dependent process models that account for manufacturing conditions such as drift, cycles, tool wear, and degradation

For organizations seeking to reduce variation, improve process capability, support audit readiness, and strengthen process-control systems, the AIAG & VDA SPC Manual is an essential reference for applying SPC with greater confidence and consistency.
