基于QFD的面向对象需求分析方法

软件开发中软件需求的获取和分析变得越来越重要。文章针对大型软件系统开发的实际,提出了一种基于QFD的面向对象需求分析方法,给出了这种方法的实施步骤和实例分析。该方法首先运用QFD的AHP工具划分需求优先级,再用"需求-措施"矩阵实现客户需求到项目特征的转换,最后用OOA方法按优先级别高低的顺序对需求进行分析,以提高软件开发效率。它具有与实践结合紧密、支持重用等特点。

Object-oriented requirements analysis method based on QFD

The software requirements capture and analysis become more and more important in software development. Considering the requirement of large management information system,an object-oriented requirements analysis method based on quality function deployment(QFD) is put forward in this paper. The QFD is introduced, and software requirements are analyzed in detail with an application case presented. In order to improve the efficiency of software development,the Analytic Hierarchy Process(AHP)tool of QFD is used first to prioritize a set of requirements, and then the WHATS-HOWS Matrix is used to move the core of research from the requirements of the project to the properties, and finally the object-oriented analysis(OOA) method is used to analyze the requirements according to the priorities. This method has several advantages over other approaches, such as being practicable, supporting reuse and so on.
