浅谈软件过程性能及稳定性的分析方法

An Analytical Method of Performance and Stability for Software Process

目前常用的软件过程模型有CMM、PSP、TSP和敏捷开发过程等,对这些过程模型的使用,需采用统计过程控制方法的控制图等工具对过程数据采样点进行分析,以便了解过程性能和过程能力,采取措施消除过程异常,保证过程的稳定性,从而提高软件开发质量。本文简要介绍了CMM、PSP等过程模型以及基于离散数据的控制图分析过程稳定性的方法。

At present,there are several software process models such as CMM,PSP,TSP and Agility software process.For these models,we need use Statistical Process Control(SPC) tools to analysis process performance data sampling,such as control charts,to quantifying the process variation,keeping process state in control and improving software quality.The paper brief introduced software process models and an analytical method of performance and stability by control charts based on discrete data for software process.
