Taguchi Explained Though Not Understood

I heard about something called Taguchi split testing. Now, you’d think I’d know what this is, being that I’m a marketing professional and all. Unfortunately, it turns out I still don’t know everything. So, off to Google where I found Taguchi Explained… For Dummies. Now, at least I understand what it is. I still have absolutely NO clue how it works. In fact, I wonder if it really even does work. I need to find a good statistics class.
