100 99% How much is it for multiple rides?
For example, suppose that the equipment has been carefully installed and debugged and the personnel have been carefully trained; Suppose a production line is composed of 100 jobs in series, and the reliability of each job reaches 99%. It looks good, but the reliability engineering theory of the system holds that the reliability of the whole production line should be equal to the product of the reliability rates of each link. 100 what is the 99% multiplication? 36%, this is the reliability of the system.
This example tells us that an enterprise or a department should not only see itself, but also consider what kind of results it will have on the whole system. It was only after World War II that people really understood this problem. Two things happened in World War II: one was the United States, where World War II14,000 planes were shot down and 210,000 planes fell by themselves. This figure shocked the American government and people. According to experts' analysis, this is a problem with the American aircraft manufacturing system. The second is Hitler, who ordered the manufacture of 10v 1 missile in World War II. When launching, there is either a problem here or there. As a result, none of them hit Britain. It is found that there are also problems in the missile manufacturing system, and the missile is composed of tens of thousands of parts. 100 times 0.99 is 36%, so what is the result of multiplying thousands by 0.99? The smaller the value, the worse the reliability of the system. Therefore, it is important to consider the problem as a whole.
We should think systematically, dynamically and essentially. This is not only a matter for philosophers, but also a core issue that every entrepreneur who pursues success must cultivate.
