管理信息系统(简称MIS)的开发是一个复杂的过程,包括系统分析、系统设计、系统研制和系统实现4个阶段,其中系统分析是最重要的阶段。因为新系统是建立在老系统的基础之上,所以对现有系统调查分析显得格外重要,系统分析的结果,直接影响到系统开发的成功与否,在这个阶段往往需要花费整个系统开发时间的一半左右。由于实际管理系统的复杂,使得系统分析必须借助于多种特定的方法和工具,业务流程图就是诸多方法中的一种。
Management Information System (MIS) development is a complex process, including system analysis, system design, system development and system implementation of four stages, of which the system analysis is the most important stage. Because the new system is based on the old system, it is especially important to investigate and analyze the existing system. The result of the system analysis directly affects the success of the system development. At this stage, it usually takes the entire system development time Half or so. Due to the complexity of the actual management system, the system analysis must rely on a variety of specific methods and tools, and the business flow chart is one of many ways.
