Now, after World War II, Mr. Toyota came to visit the Rouge, which is the huge complex that Henry Ford set up, and he brought with him his chief technical person Mr. Ohno. They went back and they tried to set up a mass production system in Japan, and they found that it wasn't working -- and it wasn't working for a variety of reasons. They had scarce natural resources, so having excess inventory was a problem. Their scale was not large enough to promote mass production. So Ohno then said, "Now, wait. The solution is not to replicate mass production. The solution is to come up with a very unique way of developing what we produce." That's where the lean production system was first born after World War II. It's taken a good 40 years for it to develop.
