摘要
需求变化的影响分析通过对其影响进行评估,为软件开发者和管理者提供有效的信息,这项工作在软件开发过程中有重要的意义.面向方面文档驱动需求工程从文本需求出发,提供了基于关注点及其关系的需求模块化、横切关注点判定及生成形式化需求文档等过程和方法.在面向方面文档驱动需求工程方法框架下,给出了一种需求影响分析方法,该方法基于矩阵确定关注点和变量之间的内部联系,应用可达矩阵计算界定关注点和变量的影响范围,定量计算关注点和变量相互之间影响程度,并通过实例分析验证了新方法的有效性.
The change impact analysis can provide some useful information to software developers and managers during software development process, so it is significantly important. Aspect-oriented document-driven requirements engineering starts from textual requirements and provides a way and process of modularizing requirements in the forms of concerns and their relationships, identifying crosscutting concerns and creating formal requirements documentation. An approach to requirements change impact analysis is given under the framework of aspect-oriented document-driven requirements engineering approach, where concerns and variables relationships have been identifies with the usage of matrix, the impact scope of concerns and variables has been calculated, the impact weights of concerns and variables has been quantified. The effectiveness of our approach has been indicated with a case study.
