McDonald's CEO Jim Skinner
Headquarters: Oak Brook, Ill.
Revenue: $23.5 billion
Employees: 1.4 million
CEO: Jim Skinner

Founded in 1961 to train new managers, Hamburger University might have a whimsical name, but it's a sophisticated operation.

At seven locations around the world, employees learn the ins and outs of running McDonald's stores, which each bring in about $2.5 million in sales a year on average.

Because of the company's franchise structure, corporate can't mandate that all managers attend, but the results make the program an easy sell: Managers who have been through training run more profitable restaurants.

Besides Hamburger U., McDonald's also operates the Leadership Institute, which focuses on the development of about 1,400 leaders globally at the director level and above.
