摘要: 风险能导致软件项目失败,从而给企业带来损失;它是软件工程的研究热点之一,人员流动风险是软件项目过程中的重大风险,然而却很少有人关注。信息熵能有效度量子系统的均匀程度,提出一种基于信息熵的定量的人员流动风险度量模型;人员对软件项目的影响越均匀,风险越小,否则,关键人员的流动将对项目造成重大影响。不仅论述了模型的合理性,而且给出了模型实例,模型中需要的数据可从企业内部获得。实践表明该模型科学合理,可以作为企业控制软件项目人员流动风险的依据。

Abstract: Risk can conduce to failure of software project,and make a loss for the enterprise.It is a focus topic for software engineering researchers.Developer turnover risk is great risk at the process of software project,yet,few scholars pay attention to it.The information entropy can be used to measure effectively the uniformity of each subsystem.A quantitative measure model based on information entropy to measure developer turnover risk on software project is provided.The more uniformly developers influence the project,the smaller the risk is,otherwise,the core developer turnover will make a huge fluctuation to the project.This paper not only has analyzed the model rationality,but has provided a model case,and the data requires in the model can be gotten in the company.The model is scientific and reasonable,which has been indicated in practice,and people can control the turnover risk better through using it.
