In human-system interaction (HSI), who does the term 'human' include?

The term 'human' in the context of human-system interaction (HSI) encompasses a broad range of individuals who engage with the system. This includes not only system operators, but also various other users such as maintenance personnel, supervisors, and even those who are indirectly impacted by the system. By recognizing all persons who interact with the system, including casual users, support staff, and any other stakeholders who may influence or be influenced by the system's operation, HSI can be designed to address a more comprehensive array of needs and interactions.

This holistic view is essential for effective systems engineering, as it ensures that the design and functionality of the system are aligned with the expectations and requirements of all involved parties, leading to improved usability, user satisfaction, and overall system performance.
