Final answer:
Frederick W. Taylor's principles of scientific management included the recommendation of a "differential rate system of piece work" and the use of time and motion studies to improve efficiency and productivity in the workplace.
Step-by-step explanation:
Fredrick Taylor's principles of scientific management were focused on increasing efficiency in the workplace. One of Taylor's recommendations was the use of a "differential rate system of piece work," in which higher rates would be paid for greater productivity and quality.
This incentivized workers to perform at their best and rewarded them accordingly. By implementing time and motion studies, Taylor aimed to standardize work processes and eliminate unnecessary steps, ultimately improving productivity for both the company and the workers.
