Rethinking Statistics for Quality Control

Quality Engineering vol. 22 issue 2 - April 2010

Abstract: As methods used for statistical process control (SPC) become more sophisticated, it becomes apparent that the required tools have not been included in courses that teach statistics in quality control. A basic description of these tools and their applications is provided, based on the ideas of Box and Jenkins and referenced publications. Elementary concepts of engineering process control (EPC) are included. Because SPC and EPC play complementary roles, the resulting technique is called synergistic control.

Keywords: Statistical process control (SPC); Concurrent engineering; Statistical quality control (SQC); Quality tools; Synergistic blending
