I would like to inform all that Dr. Taguchi passed away. The sad news was informed by Dr. Kano. I posted our three ex-chairmen's photo with Dr. Taguchi for memory at http://qualityalchemist.blogspot.hk/2012/06/remember-dr-genichi-taguchi-creator-of.html
I'm sure Dr. Taguchi will live in the heart of everyone of us.
With deepest sorrow,
