There is a vast amount of academic work on this approach, since it started in the 1950s in aviation and the 1970s in nuclear, as well as active research in oil and gas, construction, pharmaceuticals and health care in recent years. Therefore the terminology and concepts may sometimes become removed from everyday language. It is the mission of “HOP ambassadors” in our organisation to make the concepts easy to understand and apply, e.g. by sharing case studies and examples of successful implementation.
