What principles guided Frederick Taylor’s scientific approach to management?

"1. Develop a scientific approach for each element of a person’s job. 2. Scientifically select, train, teach, and develop workers. 3. Encourage cooperation between workers and managers so that each job can be accomplished in a standard, scientifically determined way. 4. Divide work and responsibility between management and workers according to who is better suited to each task. Taylor published his ideas in The Principles of Scientific Management. His pioneering work vastly increased production efficiency and contributed to the specialization of labor and the assembly-line method of production. Taylor’s approach is still being used nearly a century later in companies such as UPS, where industrial engineers maximize efficiency by carefully studying every step of the delivery process looking for the quickest possible way to deliver packages to customers."
