Ergonomists (ergonomics practitioners) contribute to the design of tasks, jobs, products and environments to make them compatible with the needs, abilities and limitations of people.

Ergonomics is a systems-oriented discipline and practising ergonomists must have a broad understanding of its full scope. That is, ergonomics espouses a holistic approach in which considerations of physical, cognitive, social, organizational, environmental and other relevant factors are taken into account.
