This paper describes a model for providing integrat ive decision-making experiences in the core undergraduate management curriculum through the use of an ERP system. The model uses ERP decision-making modules that are situated in an org anizational process and involve students in hands-o n decision making using an ERP system. We also presen t a prototype Oracle-based budgeting decision- making module for a management accounting course, a nd examine its effectiveness in teaching core concepts. These results provide the foundation for: a) developing Oracle-based exercises throughout th e management curriculum that can be used to facilitat e student understanding of integrated business processes and b) using integrated data for managerial decision making.
