** List the three definitions of 'ergonomics.'  **
According to the International Ergonomics Association, ergonomics is defined as the concern with the interactions of humans and other elements of a system in relation to their respective professions (HFESA). For instance, ergonomics applies methods and principles of design to perfect human comfort as well as overall system performance. The three definitions of ergonomics are listed as follows:  ** Physical Ergonomics  ** Physical ergonomics focuses on the characteristics that relate to physical activity. Therefore, human anatomical, anthropometric, physiological and biomechanical aspects are studied (HFESA). Some examples of the topics observed include working postures, how to handle materials safely, repetitive movements that can cause physical pain, the workplace environment, in addition to health and safety measures. Cognitive Ergonomics  **  Cognitive ergonomics focuses on mental processes in terms of perception, memory, reasoning, and motor response. These processes interrelate and ultimately affect human interactions and other elements of a system (HFESA). Some examples of the topics observed include mental workload and stress factors, decision-making abilities, skilled performance, training, in addition to human-computer interaction. Organizational Ergonomics  ** Organizational ergonomics focuses on the optimization of socio-technical systems, which includes their structures, policies, and processes. Some examples of the topics observed include communication, the design of work and working times, teamwork and participation, crew resource management, organizational culture, and quality management (HFESA).

====** Read each of the task analyses and case studies. Choose one of the case studies, and add an additional recommendation to one of them in step two as 'advice'. **==== Although Case Study 4: Wet Mopping illustrates a good number of solutions to prevent back and shoulder pains, a few others come to mind: ** ** 1)   **** Since the two cleaners are constantly bending forward when mopping the floors, it is important that they take small breaks in between by bending backwards and stretching to relax the back. **   **  2)    **** It is also important for the cleaners to wear ergonomically designed shoes that promote comfort at work. Shoes that help prevent slipping on wet surfaces is also ideal.
