I don't like the reliance on S/N ratio. I understand why Taguchi went that route. His methodology was easier in the pre-computer days, and the engineers he was working with were in the telecommunications industry where S/N ratio was prevalent.
I now use classical methods and analyze the mean and standard deviations separately. Minitab adheres strictly to Taguchi's original approach and does not provide the options available under their classical designs.
I recommend using either classical designs, possibly including response surface methods, or an EVOP approach to tuning.
Thank you so much for your ideas
To be honest the first time you mentioned classical designs I thought you are talking about DOE full factorial
but now that you named response surface and EVOP approach you got me so interested, and I want to learn them. So I'll do some research.
Thanks a lot
