基于CMM第五级上的软件开发成本、质量和开发周期的回归分析

Regress analysis of soft effort,quality and cycle time based on CMM5 projects

软件开发中,处于CMM第五级的开发团队拥有相对较高的过程成熟,而高度成熟的过程对开发成本、质量和开发周期具有重要的影响。使用线性回归模型对4个CMM第五级的团队所开发的37个项目进行数据采集和研究后,发现此时大部分被认为影响软件开发成本、质量和开发周期的因素的作用被削弱了,而其中最重要的因素是软件规模。

Software development organizations on CMM 5 possess highly mature processes which impact on software effort, quality, and cycle time. Using a linear regression model based on data collected from 37 CMM level 5 projects of four organizations, the study found that high levels of process maturity reduce the effects of most factors that were previously believed to impact software development effort, quality, and cycle time. The only factor found to be significant was software size.
