许多计算机辅助软件工程专家说,日本有可能取代美国在软件工程中的领先地位。日本为软件工程所作的努力中,不断强调质量、雇员人数和训练。可再利用性正在得到特别重视。据计算机辅助系统评价专家 E·尤尔登说,在一家日本软件开发商店中,平均有70—80%的编码是重用的。日本还正在计划建立一个全国性的软件体和可再利用编码的存贮库,这是以1985年的一项研究结果而作出的,该研究结果预测了将会发生程序的短缺。(美刊《Technology update》,1989年11月13日,Vol,45,No.46) Many computer-aided software engineering experts say that Japan may replace the U.S. leadership in software engineering. In Japan’s efforts for software engineering, quality, employee numbers, and training are constantly emphasized. Recyclability is being given special attention. According to E. Jurden, a computer-aided evaluation expert, an average of 70-80% of the codes in a Japanese software development store are reused. Japan is also planning to establish a nationwide repository of repositories and reusable codes, based on a 1985 study that predicted that there will be a shortage of procedures.
