摘　　要：从个体软件过程(PSP)的体系结构和属性出发,介绍了其描述模型和数据分析模型,以图表的方式分析了影响错误密度(DDS)和错误移去率(DRR)的关键因素,建立了非独立变量DDS和DRR与它们相应的独立变量之间的二次关系,通过这些研究得出了有意义的结论:A/FR和YIELD是影响PSP最重要的两个关键因素,因此在软件开发过程中要特别注意这两个因素。The descriptive model and data analysis model are introduced on the basis of the structure and properity of personal software process (PSP). The critical factors that influence defection density (DOS) and defection removal rate (DRR) are analyzed by means of diagrams. A quadratic relationship between the dependent variables DDS, DRR and their corresponding independent variables is established. The instructive conclusions that the A/ FR and YIELD are the most important two factors affecting PSP and they need special attention during the software development process are drawn.
