Some thoughts on the evolution of quality engineering

Abstract

Recently, Taguchi methods have become very popular among industries worldwide. Begins by reviewing the past discussion on quality engineering from viewpoints of Taguchi himself, practitioners and academic scholars. The weakness of Taguchi's approach in quality engineering is not in the statistical analysis aspect. Posits that, on the contrary, it provides a way of thinking that emphasizes a philosophy of freely using the methods of design of experiments to solve engineering problems. States that, in this regard, quality engineering will be further empowered via the aid of various engineering techniques. Proposes, based on these kind of thoughts, two directions for evolution of quality engineering.
