What are the basic principles of Frederick Taylor’s scientific management?

"Many studies of human behavior in organizations have contributed to our current understanding of these issues. A look at the evolution of management theory and research shows how managers have arrived at the practices used today to manage human behavior in the workplace. A sampling of the most influential of these theorists and research studies are discussed in this section. One of the most influential figures of the classical era of management, which lasted from about 1900 to the mid-1930s, was Frederick W. Taylor, a mechanical engineer sometimes called the “father of scientific management.” Taylor’s approach to improved performance was based on economic incentives and the premise that there is “one best way” to perform any job. As a manager at the Midvale and Bethlehem Steel companies in Philadelphia in the early 1900s, Taylor was frustrated at the inefficiency of the laborers working in the mills. Convinced that productivity could be improved, Taylor studied the individual jobs in the mill and redesigned the equipment and the methods used by workers. Taylor timed each job with a stopwatch and broke down every task into separate movements. He then prepared an instruction sheet telling exactly how each job should be done, how much time it should take, and what motions and tools should be used. Taylor’s ideas led to dramatic increases in productivity in the steel mills and resulted in the development of four basic principles of scientific management."
