The “Methods” of a Quality Master

A Quality Engineering Primer: Quality engineering (QE) techniques enable engineers to develop products and processes in a fraction of the time required by conventional engineering practice, using the least expensive materials possible, and simultaneously achieving the lowest levels of product or process variability. QE started as a form of experimental design developed in Japan in the 1950s by Genichi Taguchi. In its current application in Japanese companies and many leading Western organizations, QE encompasses much more than experimental design.
