Understood. So if I look at a conversion table that lists the equivalents of sigma, yield, DPMO, etc “Yield” in this context is referring to defectives (good output / total output) while DPMO is referring to defects?
I would say the only data that has relevence in terms of studying work content and its elements is that which you see on the floor. Using any “standard” as a substitute for actual observation is not my reccomendation.
