Admiral Hyman G. Rickover is credited with developing the first nuclear submarine. Putting together his design team, he interviewed some 14,000 graduates from some of the best universities in America over a period of five years. He became sceptical of business school graduates. He found them fluent in the jargon of systems analysis, financial manipulation, and quantitative management (whatever that is). But he claimed that they just didn't know the score.
He felt most of them had an unrealistic impression of what is involved in business and little appreciation of the importance of technical knowledge, experience, and hard work.
"What it takes to do the job will not be learned from management courses," said Rickover. "It is principally a matter of experience, the proper attitude, and common sense… none of which can be taught in a classroom."
