Historical Landmarks…..

Taylor

Taylor’s principles of Scientific Management:

1. Divide each task into parts, develop the best way to do each part;

2. Select the best person to do the each part;

3. Train, teach and develop the worker;

4. Provide financial incentives to follow the methods;

5. Managers plan the activities, and workers execute the tasks.
