Steve Jobs established Apple University to teach employees about Apple’s history and culture. Although the courses are not required, Apple’s new recruits usually do enroll.

One class instructor compared the 11 lithographs of Pablo Picasso’s “The Bull” to the way Apple builds their devices, as a way to teach the class how to communicate at Apple.

“They like to start out with an idea and whittle it down as much as possible, until it speaks just clearly enough for the consumer,” says Chen. “It’s just a general way that they try to teach employees to think about communicating.”
