Research and Training for Quality Improvement

Quality improvement is seen as an extension and democratization of use of the scientific method. The domain of such an extension has a number of dimensions that include users, disciplines, areas of endeavor, time (never-ending improvement) and the evolving discovery of new factors affecting the system. Simple tools are described, which may be used by the whole work force for studying the data continuously generated by the process, to achieve improvement. More sophisticated methods, particularly the basics of experimental design, may be used by the engineer or scientist to greatly increase the efficiency of experimentation whether intended to increase the mean, reduce the variation, or to discover designs for process and product which are robust to both component variation and environmental change.

Quality improvement; scientific method; creativity; design of experiments.
