With the intention of making Taguchi techniques more widely understood, this book covers product and process experiments designed to help Quality/Manufacturing/Design engineers make these products and processes more robust. It should enable engineers to evaluate customer loss and thereby establish realistic manufacturing tolerances. Managers should find the objective relationship of the language of engineers (specification) translated into the language of managers (profit/loss) through the use of the quality loss function. The object of the book is to give engineers a system of experimental design that should improve quality.
