At the turn of the twentieth century, America began a transformation from an agricultural economy to a manufacturing economy. Large manufacturing plants were opening and support businesses, such as banks and newspapers, were growing quickly. Without experienced managers, productivity was initially poor.
Frederick Taylor developed a theory that managers needed to develop the best way to do a task by studying the methods of doing a job with the fewest movements and then having managers ensure workers were following this “best practice”. The productivity rates of these farmers turned factory and office workers soared. First known as "scientific management" today it is known as "Traditional Management".
