The case method utilized in business schools is also used in American law schools. It relies on the principle that the most effective way to learn American law is to scrutinize judicial opinions which have become the law.
Law school cases allow students to discern a legal rule, prompting students to test their knowledge in simulated situations. This sensitivity towards facts and reliance on previous judicial rulings is deeply imbedded in the legal system in the United States.
Most American business schools base their teaching on case studies, a method which goes back over one hundred years. Business cases are descriptions of actual business situations.
Information is presented about a company: products, markets, competition, financial structure, sales, management, employees, as well as other factors influencing success. The length of business cases ranges from five to fifty pages. Case studies are based on experience.
American business schools offer degrees in business administration. The focus is primarily on analyzing quantifiable factors. The predominant subjects are finance, accounting, statistics. The methods are data-driven, structured and rigorous. The goal is to be as scientific as possible.
As of 2012 there were 662 business schools in the United States. Out of 436 schools reporting, over 168,000 students were enrolled in Master’s in Business Administration (MBA) programs in 2012 alone. From 2008-2009, 347,985 Bachelor’s degrees, 168,375 Master’s Degrees and 2,123 Ph.D.s were conferred in Business and Management. Many Americans believe in the the discipline of business administration.
The acronym for “keep it simple, stupid” is attributed to Kelly Johnson, an engineer at the U.S. weapons company Lockheed. Although there are several other variations, the principle states that systems work best if they are kept simple.
Complexity should be avoided. Johnson had given a team of design engineers a set of tools, then challenged them to design a jet aircraft which can be repaired by an average mechanic under war conditions with these tools only.
There is nothing original about KISS, however. See the statement attributed to William of Ockham that “among competing hypotheses, the one that makes the fewest assumptions should be selected”; to Leonardo da Vinci that “simplicity is the ultimate sophistication”; to Mies van der Rohe that “less is more”; and to Antoine de Saint Exupéry “It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away“.
