摘要：
Process capability indices (PCIs) have been widely used in manufacturing industry, but it is not reliable and cannot give more information about the process detailed to use them in traditional way. A method to solve the problem is "process capability plots", which can provide us information about the location and the spread of the studied characteristics and the process simultaneously. It is a powerful tool to monitor and improve the capability of industrial processes, and it should be given more attentions to for quality engineering practitioners and theorists, especially in China, where is rarely research about it. With the development of the method, four types of "process capability plots" are introduced here, users should choose suitable type of graphic method-"process capability plots" according to the actual situation of the process.
