| 摘 要: 识别软件需求变更原因并建立原因分类框架符合软件风险管理的要求。本文从软件风险管理角度出发， 分析软件风险因素与需求变更原因的共通性；根据原因存在的客观性与否，把需求变更原因分为内因和外因，并对内 因和外因所包含的各因素进行分析，建立软件生命周期中需求变更原因因素的分类结构框架。在问卷调查的基础上， 计算内外因各因素诱发需求变更的贡献度，结果表明了原因分类框架的合理性和实用性。最后给出了进一步的研究方 向。 |

| Abstract: It is essential to identify and classify the causes of requirements change for effective management of software risk.This paper deduces the mutual factors between software risk and requirements change.According to the objective principle,internal and external causes of requirements change are concluded and explained,a cause classification model of requirements change is established by the viewpoint of software life cycle,which could help easily and completely identify all factors of risk and requirements change in practice.Based on the data collected by a questionnaire,the contribution rates of each cause factor that would probably trigger requirements change are calculated,the results have shown the classification model is reasonable and practical.Finally,further research is given |
