This quote come from here:
Rochelle Kopp says it better than me.
“The challenge for Japanese companies today is that the quickening rate of technological progress is leading to radically shorted product lifecycles and rapidly emerging opportunities. The common refrain that I hear from Americans who work for Japanese companies, particularly in high tech areas, is that their companies’ decision-making processes prevent them from keeping up with what is happening in the marketplace. These employees feel handcuffed when trying to respond quickly to customer requests, or when trying to exploit a new product area. “By the time we have made a decision, the window of opportunity has closed” is a common complaint. However, in Japan there is little concept of a window of opportunity. Although not as much so as some cultures such as Latin Americans, Japanese are less likely than Americans to feel that time is a limited commodity. The attitude is that if something is a good idea, it will still be a good idea once we have gone through our decision-making process. “
