复杂软件需求开发方法研究

Research on Complex Software Requirements Development Methodologies

软件需求开发方法研究是当前复杂软件系统开发中最重要的问题之一。本文首先基于软件开发生命周期模型,对软件需求开发工作进行了介绍。进而总结了软件需求所必须包含的内容,分析了软件需求的特性。基于迭代改进的开发方法,本文将需求开发工作分解为需求捕获、需求分析、需求编写和需求确认四部分活动,并对每部分工作的详细活动和目的进行了分析和总结。软件开发工程实践证明,科学的软件需求开发方法是提高软件开发效率,提高软件开发质量的重要手段。

Software requirements development methodology is one of the most important problems for current complex software development. In this paper, based on software development life cycle model, software requirements development was introduced. Then, necessary contents that should be included in software requirements and good software requirements characteristics were presented. According to iterative development method, software development process was divided into four parts： requirements elicitation, requirements analysis, requirements documentation and requirements validation. For each part, the scope and detailed activities are investigated. Practice of software development engineering showed that, good software requirements development methodology is valuable for the improvement of efficiency and quality of software requirement.
