The entire sting reminds me of the movie Gung Ho. Yes it was a comedy movie but it was based on a can't do attitude of the US car market in the 70s up to the early 80s. I think quality control has improved since then. From research I've done quality control in Japan culture is to the point that anyone in an assembly plant can stop production if they notice a repeated defect; the same action would probably make coworkers into enemies in Western cultures.
Is anyone familiar with Deming's 14 points of Total Quality Management? I don't know which is more profound, the 14 Key Principles or the 7 deadly diseases. Both are outlined in the link below. It's funny that post war Japan would use a Western consultant to achieve quality results. The USA auto industry had their Eureka moment over a decade later.

But, just to keep it light, enjoy a few minutes of Gung Ho where a Japanese auto maker comes to the US to take over an unproductive US auto plan. 5:00-5:40 actually is kind of funny.

As for German engineering, anyone ever play the game Mouse Trap? I always think of Rube Goldberg machines at the same time (although some of the competition in this endeavor is kind of fun to watch).
