| This research sponsored by Bell Canada conducts an efficiency analysis using Data Envelopment Analysis for Access Network engineering teams at Bell. We developed two DEA models for measuring the efficiency of engineering teams: Full Activity and Economic Models. The measures in the models were formulated in collaboration with management at Bell. We collected 1994 data for each model for a total of 39 teams in Ontario and Quebec.;We also developed the Reduced Activity Model as a version of the Full Activity model which excludes held orders as an input factor. The analysis of the Reduced model verses the Full model enabled the identification of teams that exhibit particularly low levels of held orders as well as those that exhibit very high levels. The results of the unconstrained Economic Model reveal how DEA selects factor weights for each team that will enable provide the highest possible technical efficiency score. In order to prevent the assignment of unrealistically high efficiency scores, the factor weights were bound using managerial information regarding the relative input factor importance.
