Yes. So if a U.S. worker is to operate as a Japanese worker does, he has to understand the process. He has to know what's right, what's wrong, and how you fix it. Now, initially it might mean that the production line gets stopped a lot, but over time you get it right. You decrease the number of defects. Another thing that you probably noticed when you were in Japan was that you didn't have these huge bins with lots of excess parts being stored -- they're called buffers -- whereas you have that in most of the U.S. systems. That's the so-called just-in-time system, that you want to eliminate waste of all sorts. Excess inventory is waste. It costs money, but, more importantly, it masks problems. If a part doesn't fit right, chuck it and put another part in. That's the philosophy in the mass production system. Move the metal. Keep the production line running at all costs.
