In this paper we propose a composite indicator function for performance analysis. Statistical variables represent the satisfaction levels of users or consumers. When evaluation takes into account more than one aspect the problem is quite complicated and some methodological and practical issues arise: standardization, multivariate structure of data, accuracy of partial indicators, distance with respect to target (highest satisfaction level), stratification in presence of confounding factors. The methodological solution here proposed overcomes these problems and gives an easy and useful instrument for performance analysis.

Abstract
In this paper we propose a composite indicator function for performance analysis. Statistical variables represent the satisfaction levels of users or consumers. When evaluation takes into account more than one aspect the problem is quite complicated and some methodological and practical issues arise: standardization, multivariate structure of data, accuracy of partial indicators, distance with respect to target (highest satisfaction level), stratification in presence of confounding factors. The methodological solution here proposed overcomes these problems and gives an easy and useful instrument for performance analysis.
