The success value is a measure of the influence of a vote on the composition of the committee to be elected.

There is also a *relative success value* :

One speaks of success value equality when all relative success values are equal to 1 or differ only minimally from 1. You can minimize the largest difference, the mean difference or the standard deviation for each of the two values ; each of these six objectives requires a different seat allocation process .
