Taguchi’s design of experiment (doe) method is a statistical method developed by taguchi and konishi to optimize the process parameters and improve the quality of manufactured goods. Taguchi refers to experimental design as off-line quality control because it is a method of ensuring good performance in the design stage of products or processes. Taguchi has introduced the concept of designing experiments to find factor settings where variance is minimized, as well as where the mean response is optimized we can make the response insensitive (robust) to the customer or process environment (insensitive equates to minimum variance) by including environmental variables as. 1 design of experiments (doe) using jmp® and sas® charles e shipp, consider consulting, los angeles, ca abstract jmp has provided some of the best design of experiment software for years.
