Advanced Statistical Process Control

This course builds on the fundamental SPC concepts and traditional charts learned in the Statistical Process Control course.  More advanced charts that are necessary for handling modern production methods are covered in detail.  This course also teaches participants how to handle non-Normal data.  It is assumed that participants have taken Statistical Process Control (or equivalent).
