The Beer Distribution Game (Beer Game) is a simulation game created by a group of professors at MIT Sloan School of Management in early 1960's to demonstrate a number of key principles of supply chain management. The game is played by teams of at least four players, often in heated competition, and takes from one to one and a half hours to complete. A debriefing session of roughly equivalent length typically follows to review the results of each team and discuss the lessons involved.
The purpose of the game is to meet customer demand for cases of beer, through a multi-stage supply chain with minimal expenditure on back orders and inventory. Communication is against the rules so feelings of confusion and disappointment are common. Players look to one another within their supply chain frantically trying to figure out where things are going wrong. Most of the players feel frustrated because they are not getting the results they want. Players wonder whether someone in their team did not understand the game or assume customer demand is following a very erratic pattern as backlogs mount and/or massive inventories accumulate. During the debriefing, it is explained that these feelings are common and that reactions based on these feelings within supply chains create the bullwhip effect.
This game also highlights how LIVE charts and analytical data is shown to the users via our world's integration layer with Google Spreadsheet. Data is fed into the Google Apps during various levels of interactions by the players and business intelligence within the system takes care of calculations involved in profit/loss statements of teams.
