摘要:: 需求获取是软件开发过程中非常重要的环节,它贯穿于整个软件生命周期。针对系统客户和开发人员由于认识问题角度和知识的差异而存在的需求获取障碍,提出了一种基于用例的需求获取方法。该方法以用户和任务为中心,设计了一个用户需求描述模板,引导用户填写需求描述信息,开发人员利用用例驱动技术对需求描述信息进行分析和验证,最终获取全面和准确的参与者和用例信息。该构建过程不仅为构造用例图和类图奠定了基础,而且也使软件工程活动更加规范

Abstract:: Requirements elicitation is a very important part in the software development process.It runs through the entire software life cycle.According to the system customers and developers existing communication barrier due to understanding differences and perspective of knowledge,put forward a kind of requirements elicitation method based on use case.The method takes the user and task as the center,design a user requirement description template,guiding the user fill requirement description information,developers use the use case driven technique to analyse and verify the information,finally obtain comprehensive and accurate information including actors and use cases.The construction process not only laies a foundation for constructing use case diagrams and class diagrams,but also makes the software engineering activities more normative
