The fundamental principles that Taylor saw underlying the scientific approach to management may be summarized as follows:

1. Replace rule-of-thumb work methods with methods based on a scientific study of the tasks.

2. Scientifically select, train, and develop each worker rather than passively leaving them to train themselves.

3. Cooperate with the workers to ensure that the scientifically developed methods are being followed.

4. Divide work nearly equally between managers and workers, so that the managers apply scientific management principles to planning the work and the workers actually perform the tasks.
