摘要

软件系统必须不断升级,以适应不断变化的业务环境。由于当前的维护方法效率低下,许多旧的程序不能满足当前的战略需求。软件再工程的共同目标是提高程序的可维护性,并将程序转换为更新的计算机、数据库或语言。本文描述了一个战略再工程的框架,在这个框架中,为了满足公司的战略目标,对目标系统进行了实质性的重新设计。战略再造很像再开发,通过重用从现有的、仍然可行的程序中提取的信息来加速。讨论了公司战略计划对软件再工程的影响,并描述了用CASE进行战略再工程的生命周期阶段。

Strategic reengineering of software: Lifecycle approach
Software systems must be constantly upgraded to be in tune with an evolving business environment. Due to the inefficiency of current maintenance methods, many of the old programs do not meet current strategic needs. Common goals for reengineering software have been to improve maintainability of programs and to convert programs into a newer computer, database, or language. A framework for strategic reengineering in which target systems are substantially redesigned in order to meet a company's strategic goals is described. Strategic reengineering is much like redevelopment, accelerated by reuse of information that is extracted from existing, still viable, programs. The impact of a company's strategic plans on software reengineering is discussed, and lifecycle phases of strategic reengineering with CASE are described.
