The Principles of Scientific Management (1911) is a monograph published by Frederick Winslow Taylor where he laid out his views on principles of scientific management, or industrial era organization and decision theory. Taylor was an American manufacturing manager, mechanical engineer, and then a management consultant in his later years. The term scientific management refers to coordinating the enterprise for everyone's benefit including increased wages for laborers although the approach is "directly antagonistic to the old idea that each workman can best regulate his own way of doing the work." His approach is also often referred to as Taylor's Principles, or Taylorism.

Frederick Winslow Taylor was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants. In 1909, Taylor summed up his efficiency techniques in his book The Principles of Scientific Management which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. His pioneering work in applying engineering principles to the work done on the factory floor was instrumental in the creation and development of the branch of engineering that is now known as industrial engineering. Taylor made his name, and was most proud of his work, in scientific management; however, he made his fortune patenting steel-process improvements. As a result, scientific management is sometimes referred to as Taylorism.
