The imprint of Taylor’s Scientific Management Theory can be found in all aspects of management theory as he was the first person to look at work as something to be researched.

Taylor was an American inventor and engineer who applied his engineering and scientific knowledge to management and developed a theory called scientific management. His most important work is contained in the book, The Principles of Scientific Management (1911).
Taylor’s principles of scientific management theory can be seen in nearly all modern manufacturing firms and many other types of businesses. He was one of the first advocates of matching employees to work as an alternative to firing. Knowledge of these principles can lead to an appreciation of the importance of quantitative analysis, or the analysis of data and numbers to improve production effectiveness and efficiency.
