Design & Factor Selection
Design Types & Categories
Taguchi designs are fractional factorial designs with the order of the factors or rows revised from the standard order. In this way, Taguchi did not develop any new designs. Some practitioners feel that his design construction is more complicated, obscuring the interactions or factor effects.
Instead, Taguchi’s contributions to design were in his recommendations for screening designs to include the effect of variance. Taguchi emphasized the use of replicates, including subsidiary (or noise) factors, to estimate variance.
