The Beer Game is still today, one of the tools with the greatest impact in demonstrating that the behaviour of a system is generated by its structure. However, we believe that in its original form too much time is needed to play it and carry out a proper debriefing. In addition, it is not always easy to guarantee the hypothesis of isolation for the different positions within the game. Finally, we feel that participants often have difficulty in picking up quickly and clearly the process characterizing the game. To deal with these and other problems we have introduced certain modifications which, in our view, totally or partially resolve these difficulties.
