The paper details the variety of Taguchi methods, as important contribution to the quality
improvement. The extended use of these methods imposes more and more complex calculi for the practical
application and optimization. It should be necessary to benefit by the new software developments, assisted by the
advanced statistical methods. The paper presents a few particular applications of some statistical software for
the Taguchi methods as a quality enhancement insisting on the quality loss functions, the design of experiments
and the new developments of statistical process control
