We'll tolerate a certain amount of poor quality. The Japanese say, have just enough inventory for the cars you're going to build. If all of a sudden you run out of inventory, something's wrong. Find out what's wrong and fix it. Now, you might have seen a lot of automation, but, in fact, the competitive advantage of the Japanese system or of the lean production system is not automation. The competitive advantage is a different way of organizing the way we make things. Now, if you do that right, then you have a system which is perfect for introducing automation. One of the things we looked at was comparison of how successful automation has been when superimposed on mass production and how successful automation has been when superimposed on lean production. What it clearly shows is that lean production provides the foundation and the framework that allows automation to work.
