SPC Training

Basic SPC (2.5 days) and Advanced SPC (2.5 days). The training is presented to the general public in open enrollment or "in plant" customized seminars.

The Basic seminar deals with the fundamentals of single variable SPC whereas the Advanced seminar deals with the multi-variate aspects of SPC which become of greater importance as your rapid data collection capabilities increase. The emphasis of the seminars is on the demonstration of the various techniques using real data from past seminars and projects or from data furnished (disguised or not) by the various class members themselves. This approach has proven to be extremely effective many times.

Our next SPC Course(s) will be held:
