In this paper, a new process capability index 'Multivariate Process Capability Mean(MPCM)' is proposed. The existing process capability indices are concerned with the single variable. In many cases, a quality characteristic is composed with several factors. In that case, we want to know the integrated process capability of a quality characteristic not those of each factor. We induced the concept of process capability mean to the number of multivariates. For the concept of MPCM, we illustrated an example. Sensitivity analysis is done for the MPCM and the number of variables.
