About a decade ago American government realizes that they are to be beaten by other countries in the automotive sector if they don't put their heads together. Then they decide to deploy a council to make a research.The group visits a Japanese car factory and notice something strange. Everywhere in the factory, there are lots of cats wandering around. One of the American group members asks the general manager of the factory about the cats. He replies; -we put a cat into each completed product at nights, then if one is alive next morning, that means there is something wrong with the isolation of that unit, so we unassemble it and fix it. Americans were amazed...Then it was time to see what it was like in Turkey, they came to TOFAS factory for their search. And they were again surprised as they saw cats like they used in Japan and they asked again about the cats. General manager's answer was ; -we put a cat in each completed unit at night, if it the cat is missing in the morning ,it means we have some problem with the isolation of that unit.
