HFE principles are rooted in socio-technical values. This assumes a broad understanding of other HFE areas however, actual problem solving requires participatory approaches through consultation with HFE specialists in different domains as well as specialists in other relevant fields. In order to practice effectively, human factors and ergonomics professionals who are specialists in a given domain or discipline must address issues and challenges with sufficient consideration of all of the relevant elements of HFE. HFE takes into account physical, cognitive, sociotechnical, organizational, environmental and other relevant factors, as well as the complex interactions between the human and other humans, the environment, tools, products, equipment, and technology. The issues HFE addresses are typically systemic in nature thus HFE uses a holistic, systems approach to apply theory, principles, and data from many relevant disciplines to the design and evaluation of tasks, jobs, products, environments, and systems. HFE is a multi-disciplinary, user-centric integrating science. The terms ergonomics and human factors are often used interchangeably or as a unit (e.g., human factors and ergonomics – HFE or EHF), a practice that is adopted by the IEA.Īlthough HFE practitioners often work within particular economic sectors, industries, or application fields, the science and practice of HFE is not domain-specific. Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and methods to design in order to optimize human well-being and overall system performance. The word ergonomics - “the science of work” is derived from the Greek ergon (work) and nomos (laws).
