Taguchi methods to improve the development process

A description is given of the Taguchi methods, which compromise combinations of engineering, statistics, economics, and information theory that greatly improve product development. Product parameter design optimizes the nominal values of design parameters to keep performance near complete customer satisfaction despite variances of parts and environment. Tolerance design selects the basic precision level that minimizes total cost. Process parameter design optimizes process parameters to maximise the intrinsic stability of production. Online quality control periodically checks and adjusts production to maintain operating precision that minimizes total cost
