需求过程模型的综合评价方法

Comprehensive evaluation method of RE process models

需求过程质量有益于改进需求的质量.为了在实际需求工程环境中更好地复用已有需求过程模型,提出一种基于过程情境特征的模型适用性综合评价方法.首先提出了用以评价需求过程模型适用性的过程情境特征指标体系;然后,构造了过程情境特征的权重确定方法;最后,提出了一种适用于需求过程模型的综合评估方法.通过应用表明,它能够在项目情形适用性、过程性能与需求质量效用3个方面对待选需求过程模型进行综合评价.

The quality of requirements engineering （RE） process is beneficial to the quality improvement of software requirement. A model for applicability comprehensive evaluation method named MACEM is proposed, which is used to make a better reuse of the existed models of RE process. First, the situation char- acter index system to evaluate the requirement of the application process model is proposed; then, a new method is defined to account the weight values of process situation character; finally, the MACEM method is constructed to evaluate the RE process models comprehensively. As a result of a practical application, this MACEM method is proved to be able to implement comprehensive evaluation to the optional RE process models for the current situation which includes project characteristic, the performance of process and requirement quality effectiveness.
