我国企业使用过程能力指数情况调查与分析

文章对我国企业使用过程能力指数情况进行了问卷调查。结果显示,我国企业过程能力指数应用中存在的主要问题有：首先,计算过程能力指数的企业不多,且分布不平衡;其次,过程能力指数的可信度不高;再次,不考虑样本的随机性,简单地根据基于样本数据计算的点估计值就给过程的绩效下定论。这些问题的存在,为学者的相关研究提供了视角,也为企业、培训机构、行业协会、有关管理部门开展与过程能力指数有关的活动提供了参考依据。

Survey and Analysis on the Application of Process Capability Indices in Chinese Enterprises

This paper investigated the application of Process Capability Indices（PCIs） in Chinese enterprises by questionnaire. We can draw the following conclusions from the questionnaire. Firstly, few enterprises use the PCIs so that the PCIs can＇ t play a part in the quality management. What is more, the number of enterprises distributes unbalanced in different regions. Secondly, even if the PCIs are estimated, their credibility is low. Thirdly, the enterprises draw a conclusion of their process quality only according to the value of point estimators for the parameters of the PCIs without considering the fact that all the estimators are random.
