一种利用UML的软件需求阶段风险评估方法

New Methods of Software Requirements Risk Assessment Using UML

在软件开发活动早期阶段评估软件的风险及其影响程度将有效减少软件开发成本和降低软件开发风险。针对目前软件风险评估的研究主要集中在软件过程的中后期阶段的现状及遵循"尽早识别和控制风险"的实践准则,提出了一种在软件需求分析阶段,利用UML建模图形度量软件风险的方法。该方法主要关注在软件需求分析阶段预防软件风险,为降低风险在软件开发后期产生严重影响提供优化参考。

Evaluating software risks in the early stages of software development activities will effectively reduce the level of software development costs and the development risk.Aiming at the status that the current research on the software risk assessment mainly focuses on late stage of the software development,and following the practice principle which is ＂early identification and control software risk＂,this paper presented a method for assessment software risk at requirements analysis phase using UML.This method primarily focuses on the software risk prevention at requirements analysis phase,and sequentially gives some reference to reduce the risk impact of the late phase.
