Final answer:
Fredrick Taylor and the Gilbreths advocated for scientific management, focusing on time-motion studies and improving workplace efficiency and productivity.
Step-by-step explanation:
Fredrick Taylor and the Gilbreths were proponents of scientific management. Taylor, an engineer and management consultant, is most well-known for his work in industrial efficiency and human productivity. His 1911 seminal book, 'The Principles of Scientific Management,' laid the groundwork for modern management practice. This included the famed time-motion studies and the standardization of work tasks. Taylor believed that the ultimate goal of management should be the maximization of profitability for the employer, coupled with the ideal outcome for the employee, which could be achieved through systematic training and development.
Frank and Lillian Gilbreth, on the other hand, were also pioneers of time and motion studies, but they had significant contributions in the field of ergonomics or human factors psychology. They focused on improving the fit between the worker and the technology they used, which had the effect of increasing productivity and easing the work process. In summary, option 5) Scientific management is the appropriate answer to the student's question as both Fredrick Taylor and the Gilbreths advocated for scientific management practices.
