摘　　要：软件度量在软件开发过程和软件产品中具有重要作用。GQM(Goal-Question-Metric Approach)模型是当前使用较为广泛的一种软件度量手段,它通过对目标的一系列问题的回答最终实现对软件开发过程的控制和评估。针对GQM中没有提及如何客观地将组织的目标归纳和分解为度量指标这一缺陷,提出一种利用德尔菲法和PUGH矩阵的决策机制,对众多分解的度量指标进行筛选,最终形成GQM模型的问题和度量元,并结合实际实践进行分析和验证。实践表明该决策机制能够有效地形成GQM度量计划,从而指导软件开发过程和软件产品质量的提升。Software metrics play an important role in software development processes and software products. GQMmodel is a kind of software measure which is widely used. It can control and evaluate theby answering a series of questions. Aiming at the shortcomings of GQM not to mention how to objectively summarize and decompose the goals of the organization into metrics , this paper proposes a decision making mechanism using Delphi method and PUGH matrix to select the measures of many decompositions. Finally , the problems and metrics of the GQMmodel are formed , and the analysis and verification are carried out. Practice shows that the decision-making mechanismcan effectively form a GQM measurement plan to guide the software development process andprovement.
