: Specific, identifiable errors or changes that signal a process is out of control. The Seven Quality Tools :
: Categorical counts, such as "pass/fail" or the number of surface scratches. Typical Implementation Steps SPC-3 | Statistical Process Control - AIAG
: Continuous measurements like length, weight, or temperature. Statistical Process Control, Reference Manual
: Unlike traditional inspection that filters out defects after production, the manual emphasizes a proactive system to identify and eliminate causes of variation during the process.
The is a foundational resource, primarily developed by the Automotive Industry Action Group (AIAG) , that provides standardized guidelines for monitoring and improving manufacturing quality. Overview of the SPC Reference Manual : Specific, identifiable errors or changes that signal
: For visualizing the distribution and spread of data.
: Random, inherent fluctuations in a stable process. : Unlike traditional inspection that filters out defects
: It serves as a guide for using basic and advanced statistical methods to improve the value of products and services for customers. Key Concepts from the Manual Variation Types :
