This paper is devoted to the study of product commonality effects, i.e. the replacement of two, or more specific components by a single one. We study the impact of commonality when specific product demands follow a binormal distribution. It is shown that commonality is more efficient when the correlation between the demands of products is close to -1 and when the gap between the demand variances is small. An original commonality index aimed to measure the performance of various product configurations is finally developed.
