International Journal of Management and Decision Making (IJMDM), Vol. 11, No. 5/6, 2011

Abstract: This article presents a methodology to compare call centres performances efficiently and systematically. Three units attending the calls of clients of a telephonic services company are comparatively evaluated. The approach proposed contemplates, besides information on costs, the analysis of criteria associated to the clients' satisfaction and seasonal factors affecting the demand for the service. An analysis based on a probabilistic composition of preference criteria is developed, which results in ranking, according to different points of view, the performances of the different service centres along the year. Different forms of composition treat quality and cost criteria together and separately. The results of the application of these different forms of composition are employed in a group decision process.
