中文摘要：

统计过程控制（SPC）是通过使用控制图来制定过程决策和预测过程行为的一种质量控制方法。SPC的方法用于软件过程,可以通过描述过程行为来监控过程的稳定性。讨论了将SPC应用于软件测试过程,针对测试过程中所度量的不同分布形式的数据而采用不同计算方式应用SPC的控制图,然后根据控制图判断测试过程是否稳定,并分析可能存在的可归属原因。

英文摘要：

Statistical process control （SPC） is a quality control method that is used to monitor process behavior and measure process performance. Software testing process （STP） is a quality control process in software development, and there is an increased interest in using control charts for monitoring and improving software processes. The application of SPC to the STP is discussed, and two different patterns is contrasted when applying SPC method. According to different data distribution in the STP, corresponding transformation in SPC can brings appropriated control charts. Furthermore, cause analysis of instability in STP is briefly introduced in the end.
