Abstract: By using mathematical modeling analyses to set up the evaluation model of cost & quality function for the purpose of software-developing projects’ organization pattern, the effectiveness of three kinds of organization patterns are evaluated: pattern 2 is suitable for high-end markets, pattern 3 is suitable for middle level markets, while pattern 1 is used for low-end markets. The correctness of the conclusion of theory analyses is hereby verified in the case studies.

Key words: Software-developing projects; Organization pattern; Evaluation; Cost & quality function

摘要： 用数学建模分析方法，构建软件项目开发组织模式的成本质量函数评价模型，并据此评价3 种组织模式的效能，认为高端市场适用模式2，中端市场适用模式3，低端市场适用模式1，并结合实际案例验证理论分析结论的正确性。
