Editing Beer distribution game (section)

=== Traditional board game === 

The traditional version of the beer game is a physical board game where people have to move actual objects. The tokens on the board game represent orders and stocks of a supply chain process. The main disadvantage is that this type of beer game takes much more time than the software version. Moreover, it is quite complex to play it since people need physical objects that represent the inventory on the board. Additionally, inventory levels of other supply chain stages are transparent and are therefore quite hard to estimate.<ref name=TBG />
