The purpose of this paper is to provide insights into how supply chain management canbe taught using megagames as a pedagogical motor. This study has had a longitudinalaction research approach to student centred learning as it builds on a previous paper onintroducing a theme of cross-functional decision-making through combining lectures,case assignment, and computer-based tools. Combining case work and the megagame hasled to activity independence and room for new reflections. What can be seen is thatexchanging the computer-based tool for a megagame has allowed students a deeperunderstanding of not only decision-making, but also decision-formulation.
