Univariate indices are not adequate for assessing the capability of processes with multiple characteristics. Among all developed multivariate process capabilities, index has the most accurate estimation of Cpm. takes into account both the ratio of the tolerance region to the process region and the probability of nonconforming product. However, the exact probability distribution of is too complicated to be derived. Consequently, the related hypothesis testing and confidence interval cannot be developed.

在众多的指标当中，单变量制程能力指标的发展已趋成熟，而多品质特性的制程能力指标还在持续的发展中，其中多品质特性制程能力指标是所有多品质制程能力指标中估计值最准确的指标，但在利用多品质制程能力指标Cpm来评选两个制程的制程能力时，由於指标之机率分配过於复杂，迄今未能推导出其相关的统计假说检定或信赖区间，因此无法发展出检定两个制程能力指标Cpm是否有差异的统计检定程序。
