A combination of factors such as an ageing workforce and growth in emerging international economies is resulting in substantial increases in the demand for operators in many high-reliability domains. For instance, in the aviation industry, it is estimated that 498,000 new commercial airline pilots will need to be trained over the next 20 years (Boeing Commercial Airplanes, 2013). An issue associated with a workforce comprising operators who have not accumulated sufficient experience to have developed expert cognitive processing skills, so called lessexperienced operators, is the increased potential for error due to limitations in human information processing.
