Statistical Process Control II - Trending Data (1-day)

Part of our Six Sigma program.


Dr. Wayne A. Taylor

Course Description

A follow-up to Statistical Process Control I – Introduction, focusing on applying control charts in manufacturing to improve and maintain process performance.  Topics include determining the number of samples to select, the sampling frequency, how to handle out-of-control points, and how to handle common complications such as multiple characteristics, multiple stations and short production runs.  Control charts for the average, median, range, standard deviation, percent defective and counts are all covered. It also teaches how to effectively implement SPC in a manufacturing plant.

The class is hands on. Several exercises involve the actual collection and analysis of data generated in class. The course is also full of practical advice on how to effectively utilize SPC.  Four detailed cases studies demonstrate the proper role of SPC and potential pitfalls to avoid.  It clarifies where capability studies and control charts fit into the Six Sigma Design and Six Sigma Improvement processes.  Much of the material is from the book Optimization & Variation Reduction in Quality
