The Beer Game

The Beer Game The purpose of the Beer Game is to experience systemic effects and to introduce the need for supply chain and network management. Specifically it shows: How single parts in a system influence each other. How individual thinking differs from systemic thinking(network thinking). Potentials for systems optimization and the use of information systems

The Beer Game "The game is far simpler than a real supply chain. There are no random events-no machine breakdowns,transportation problems,or strikes. The structure of the game is visible to all.Players can readily inspect the board to see how much inventory is transit or held by their teammates
