Ford pioneered the just in time parts inventory system that is admired and used throughout the manufacturing world. The downside of this lean inventory system is when a key supplier cannot deliver parts and the entire line must shut down.
Actually you can point to Toyota for this. They started back in the 60s as part of what they call lean manufacturing. Multiple companies teach the "Toyota way". The company I work for sent a lot of us to a local college to learn it. There's a lot of quotes that credit this that and the other thing but when you actually take the course (2 week long) and they go into the history it really comes down to the way Japanese think. Just like the Germans are known for precision.
We used light bright pegs on a wooden board. The first time was a free for all. All we were told was to do was produce as many as we could. There were 4 stations and each station had to put a certain number of peg of a color in specific locations. We were timed for 10 minutes. The second time was with a little structure. The final time was using just in time. The station would only provide the next station with one unit. The difference was noticeable. The problem, of course, is when the station (or in this case factory) before you can't provide work for your station.
