"[Fredrick Winslow] Taylor sought to precisely measure the movements of factory workers and their timings to make them as efficient as humanly possible. This made him beloved by executives and detested on the factory floor, and it also made him one of the world's first management consultants. In a recent article in The New Yorker, 'Not So Fast,' the historian Jill Lepore takes a hard look at Taylor and his claims for scientific management. According to new research, he was a better salesman than consultant. Many of his facts were made up, and most of his results never materialized. We now know that Lillian Gilbreth, an early proponent of scientific management, had serious doubts about the movement she helped proselytize.
All this is important because Taylor, with his system of scientific management, was the father of efficiency. From scientific management we get the lust for efficiency in business. It became part of the dogma of business schools, almost none of which existed before his time. Business schools from their earliest days have promoted efficiency and the handling of business as something like industrial engineering. From operations to finance, from marketing to sales, business school education has focused on narrowing problems, identifying resources and working to get the most out of the least."
