在数家知名企业从事过管理的汪中求,写了一本《细节决定成败》的书。他指出,“细节”不“细”,许多事物成败的关键就在于“细节”如何。为此,汪中求将德国人设计的上海地铁一号线和国人设计的二号线作了比较。上海多雨,所以一号线每个室外出口都设计了三级台阶,这三级台阶雨天阻挡了水的倒灌, Wang Zhongqiu, who has been engaged in management in several well-known companies, wrote a book entitled “Details Determine Success or Failure.” He pointed out that “details” are not “fine”, and the key to the success or failure of many things lies in “details.” To this end, Wang Zhongqiu made comparisons between the Shanghai subway line No. 1 designed by the Germans and the No. 2 line designed by the Chinese people. Shanghai is rainy, so each line of No. 1 line is designed with three steps. This three-step step blocks the backflow of water.
