Query: shoud rename the title

I'm also surprised by 4 stars & other praises of this book (e.g., Fortune).the book should be renamed "Case Studies of Taguchi Method" and the "authors" should be renamed as "editors"it also does not telll you the method & its statistical basis, its strength & weakness compared with other methods, its assumptions and so forth. In addition, it lacks a biblography. Overall, we are just supposed to take a leap of faith. The book feels like "informercial"
