Abstract: Based on the decomposition and analysis of the organizational goals，applying the classical technology of Statistical Process Control（SPC），this paper establishes the Goal-based Software Process Performance Assessment Model（G-SPPAM）.Through analyzing the mapping relation among organizational goals，measurement indictors and sub-processes，the article achieves assessment of each sub process.Finally，gaves an application of this model and analyzing it by combining an example.

Key words: software process, measurement, software process performance, assessment model, statistical process control

摘要： 基于组织目标的分解和分析，应用经典的统计过程控制（SPC）技术，建立了基于目标的软件过程性能定量评价模型（G-SPPAM）。通过分析组织目标（Goal）、度量指标（Indictor）和软件子过程（Sub process）之间的映射关系，实现每一个子过程的定量评价。还给出了该模型的应用方法，并结合实例分析了该模型。
