   Springfield Hospital

   Susanna Gallani and Robert Kaplan

   One of the key roles of costing systems is to support the evaluation of performance and facilitate appropriate resource allocations. Through participation in a comparative cost study, management at Springfield Hospital, known for its heavy focus on operational excellence, become aware of opportunities for further improvement. Analysis of the differences in costs, uses, and allocations of resources will inform management in the decision and implementation of strategic plans. This case stimulates reflections on the importance of costing systems, in particular Time-Driven Activity Based Costing, and variance analysis as decision support mechanisms.
