Quality was the watchword of 1980s, and Genichi Taguchi was a leader in the growth of quality consciousness. One of Taguchi’s technical contributions to the field of quality control was a new approach to industrial experimentation. The purpose of the Taguchi method was to develop products that worked well in spite of natural variation in materials, operators, suppliers, and environmental change. This is robust engineering.
Much of the Taguchi method is traditional. His orthogonal arrays are two-level, three-level, and mixed-level fractional factorial designs. The unique aspects of his approach are the use of signal ...
