There is a wonderful story of a group of American car executives who went to Japan to see a Japanese assembly line. At the end of the line, the doors were put on the hinges, the same as in America. But something was missing. In the United States, a line worker would take a rubber mallet and tap the edges of the door to ensure that it fit perfectly. In Japan, that job didn’t seem to exist. Confused, the American auto executives asked at what point they made sure the door fit perfectly. Their Japanese guide looked at them and smiled sheepishly. “We make sure it fits when we design it.” In the Japanese auto plant, they didn’t examine the problem and accumulate data to figure out the best solution—they engineered the outcome they wanted from the beginning.

Every instruction we give, every course of action we set, every result we desire, starts with the same thing: a decision. There are those who decide to manipulate the door to fit to achieve the desired result and there are those who start from somewhere very different. Though both courses of action may yield similar short-term results, it is what we can’t see that makes long-term success more predictable for only one. The one that understood why the doors need to fit by design and not by default.
