基于SPC的软件需求度量方法

Measurement of Software Requirement Based on SPC

软件需求管理是软件生产与质量管理的重要内容 .面对今天以需求变化难以控制为主要特点的软件危机 ,我们一方面必须采用更加合适的软件工程和需求工程方法 ,去适应需求的不断变化和增长 ;同时还必须采用合适的度量方法和手段 ,去分析需求变化的趋势和原因 ,并控制和管理需求的变化 .该文提出了一种以统计过程控制原理对软件项目的需求变化进行统计控制 ,并对异常波动进行度量分析的软件需求度量方法 .

Software requirement management is very important in software development and quality management. Today, the essence of software crisis is the uncontrolled ever-changing software requirement. So we must adopt more appropriate software engineering method and requirement engineering method to accommodate these changes, and meanwhile we also must use effective measurement to analyze the trend and cause of changes, and then control and manage the changes. In this paper, we introduce an interest method based on SPC to control the change rate of software requirement, and analyze the cause of significant deviation.
