ABSTRACT
Human factors and ergonomics (HF/E), as a professional activity, has now been introduced to almost all economic sectors. In the primary sector, HF/E helps to improve human involvement in mining, oil and gas extraction, agriculture, and forestry. In the secondary sector, HF/E is embedded in manufacturing and construction to produce nished products. In the tertiary (service) sector, hospitals and health-care organizations, telecommunication, wholesale and distribution organizations, and governments all employ or contract HF/E services. In the quaternary (knowledge-based) sector, HF/E practitioners are employed in information and technology, media, education, research and development (R&D), and consultancy organizations.
