This highly interactive business simulation encourages participants to work together to solve challenges within their small teams as well as within the larger overall group. Each small team of people works in an area adjacent to the working areas of other teams. Groups use limited supplies to construct a device that will safely transport a number of marbles with each team’s section of track while connecting those before and after it. Challenges are included to reinforce the theme of uncertainty, how best to communicate and negotiate with others, distribution of resources and big-picture thinking.
