Statistical Process Control (SPC) for Operators

Course Length: 8 hours (typical)

This course offers applications of the SPC techniques that are an integral part of the corporate-wide quality control effort. Participants are introduced to the concept of variation and how it can be used as a powerful tool in quality control activities.  

The course also provides practical learning of measuring systems for accuracy, reproducibility, repeatability, and when SPC is appropriate. Types of control charts include Xbar-R, X-moving R, P, C, nP, and U charts.  The Shewhart analysis is presented via examples and understanding of the statistical significance of each out-of-control condition.  

Participants will work in teams in hands-on practical exercises that demonstrate the relationship between sigma levels, Cp, and Cpk values.
