Is Taguchi Good for Multivariate Testing?
Customer Experience Matrix
MARCH 19, 2007
I’ve spent a lot of time recently talking to vendors of Web site testing systems. Some vendors use it heavily; some make it available but don’t recommend it; others reject it altogether. Vendors in the non-Taguchi camp tell me they’ve done tests comparing Taguchi and “full factorial” tests (which test all possible combinations), and gotten different results. Incidentally, I tried to do a quick classification of which vendors favor Taguchi.
