Abstract: In software engineering, software requirement always is a most important phase. The quality of the software requirement directly concerns software development’s success. This article presents a method of software requirements based on rational unified process from the practice view, and takes local area network management system(CNETMAN) as the example to demonstrate its application process in practice. And presents how to use the software requirements architecture when software requirements have changed.

Key words: Rational unified process, User requirements, System requirements, Use-case

摘要： 软件需求向来都是软件工程中最重要的一个环节，软件需求的质量直接关系到软件开发的成功与否。该文从实践的角度给出了一个基于统一过程的软件需求的分析方法，并以CNETMAN局域网管理系统为例，介绍了它的实际应用过程。给出了当需求变更时如何使用所创建的软件需求结构。
