Abstract

New programmers, some managers, and lots of users don't understand the advantages of a structured software life-cycle. However, only a single experience with coding while designing will convince any incipient software engineer that a controlled process is needed from the time of system concept though the last maintenance phase. Software Configuration Management has become almost a religion, and EDP auditors have even encountered a few systems that appear to have been specified, then designed, then implemented, then tested, and finally installed—all before maintenance and redefinition occurred. Perhaps the millennium has finally arrived, and software people will soon live in a controlled world with rational practices. If you are tempted to believe the foregoing prediction, read the latest issue of FORTUNE, the WALL STREET JOURNAL, or COMMERCE BUSINESS DAILY and note a few problems that may divert us from the path to Nirvana. Data Processing supports commercial, educational, industrial, and governmental activities that are frequently (and repeatedly) redirected. Under circumstances of a largely random environment with thorough business planning a rarity, a critical support activity can expect to be redirected frequently. New ideas will be sliced into partly-completely DP projects, and users “analytical analyses” will become DP systems as if by magic.

结构化生命周期假设

新的程序员、一些管理人员和许多用户不理解结构化软件生命周期的优点。然而，只要在设计时有一次编码的经验，就能让任何一个刚起步的软件工程师相信，从系统概念到最后的维护阶段，都需要一个受控的过程。软件配置管理几乎已经成为一种信仰，EDP审计员甚至遇到过一些系统，它们似乎已经被指定，然后设计，然后实现，然后测试，最后安装——所有这些都发生在维护和重新定义之前。也许千禧年终于到来了，软件开发人员将很快生活在一个理性实践的受控世界中。如果你想相信上述预言，请阅读最新一期的《财富》、《华尔街日报》或《商业日报》，并注意一些可能使我们偏离涅槃之路的问题。数据处理支持频繁(反复)重定向的商业、教育、工业和政府活动。在很大程度上是随机的环境下，很少有周密的业务规划，关键的支持活动可能会经常被重新定向。新的想法将被分割成部分完整的DP项目，而用户的“分析分析”将像变魔术一样变成DP系统。
