Global Management Challenge (GMC) is a strategic management competition for managers and university students. Participants form teams of 3-5 members, and each team is placed in a group of 5-8 teams, depending the competition. The teams are then given a virtual company, initially identical to every other company in the competition. Each team then develops their company by making a series of decisions relating to every aspect of the business, such as how many machines to buy, or how much to spend on advertising. In each round, five sets of decisions are taken, corresponding to five quarters. A quarter is a period said to span three months.
