Final answer:
Frank and Lillian Gilbreth's time and motion studies were primarily focused on making workers more efficient and reducing fatigue, not just in industry but also in everyday settings, fostering the ergonomic integration of technology and human efficiency.
Step-by-step explanation:
Frank and Lillian Gilbreth are credited with conducting time and motion studies primarily to make workers more efficient by reducing the number of motions required to perform a task. Their focus was on helping workers reach their full potential and reducing fatigue. Not only were these methods applied to industry, but also to the home, office, shops, and other areas. Lillian Gilbreth, known as the mother of modern management, investigated employee fatigue and time management stress and recognized that many employees were motivated by money and job satisfaction. The contributions of the Gilbreths, such as the idea to put shelves inside refrigerator doors and using a foot pedal to operate the lid of a trash can, are reflective of their focus on efficiency and ergonomics in both the workplace and everyday life.
