Abstract

In data envelopment analysis (DEA), operating units are compared on their outputs relative to their inputs. The identification of an appropriate input–output set is of decisive significance if assessment of the relative performance of the units is not to be biased. This paper reports on a novel approach used for identifying a suitable input–output set for assessing central administrative services at universities. A computer-supported group support system was used with an advisory board to enable the analysts to extract information pertaining to the boundaries of the unit of assessment and the corresponding input–output variables. The approach provides for a more comprehensive and less inhibited discussion of input–output variables to inform the DEA model.
