With the revised curriculum 2012, we are starting to introduce the beer game simulation for the undergraduate class of systems modeling this year. This was the largest size of beer game participants ever conducted by us so far with nearly 100 participants. We have to use the main hall at the 5th floor of the department building for this simulations with the help of all SEMS Lab assistants. One lab assistants was assigned to mentor one board after the initial instructions briefing. As usual a lot confusions on the start of the game, however with the improved instructions using animated slides and one mentor one board, the process went faster than what we are predicted. As usual also, with the progress of the game, faces of confusions, excitement or shocked rose during the game.
