有一位青年在美国某石油公司工作,他所做的工作很简单,就是巡视并确认石油罐盖有没有自动焊接好。石油罐在输送带上移动至旋转台上,焊接剂便自动滴下,沿着盖子回转一周,作业就算结束。他每天如此,反复好几百次地注视着这种作业:罐子旋转一次,焊接剂滴落三十九滴,焊接工作便结束了。他想,在这一连串的工作中,有没有什么可以改善的地方呢?一天,他突然想到:如果能将焊接剂减少一两滴,是不是能节省 A young man who worked for a petroleum company in the United States did very simple work of inspecting and confirming whether or not the lid of the oil tank had been automatically welded.

Every day, he watched this operation repeatedly hundreds of times: the jar was rotated once and the solder dropped by thirty-nine drops, and the welding work was over. He wondered if there was any room for improvement in this series of work. One day he suddenly thought that if we could reduce the amount of solder by one or two drops, would it not be a saving?
