AIAG manual requires Cpk ≥ 1.33 for existing processes, ≥1.67 for new or safety-related characteristics. Aiag Spc Manual

Until an official update is released, the 2nd edition remains the absolute requirement. Always check the "IATF 16949 Sanctioned Interpretations" and your CSR matrix.

The AIAG SPC Manual provides the tools to detect special causes so they can be eliminated, and to monitor common causes to ensure they remain within acceptable limits.

While the manual allows manual calculations (X-bar/R using A2, D3, D4 factors), most Tier 1 suppliers require automated SPC software (InfinityQS, Q-DAS, WinSPC). Auditors will check that the software’s formulas match the AIAG manual (specifically regarding the bias correction factor for standard deviation). Always check the "IATF 16949 Sanctioned Interpretations" and

In the high-stakes world of automotive manufacturing, a defective part isn't just an inconvenience—it's a liability. A failed brake caliper, a misaligned sensor, or a brittle fuel injector can lead to massive recalls, legal action, and loss of human life. This is why the Automotive Industry Action Group (AIAG) created its suite of core quality tools. Among them, the (Statistical Process Control) stands as a non-negotiable standard for suppliers across the globe.

While there is no single "paper" that replaces the official manual, several high-quality resources and academic articles cover the AIAG Statistical Process Control (SPC) Reference Manual

The is a reference guide published by the Automotive Industry Action Group. First released in the early 1990s and now in its 2nd edition (with significant updates), the manual standardizes how automotive suppliers collect, analyze, and interpret process data.

The entire philosophy of the AIAG SPC Manual rests on Dr. Walter Shewhart’s 1920s work.
