Methodological issues in systems Human Factors and Ergonomics: Perspectives on the research–practice gap, reliability and validity, and prediction

The changing nature of work and society, and a proliferation of complex global challenges, is increasing the need for systems Human Factors and Ergonomics (HFE). The discipline is well equipped to respond, but there remain a number of longstanding issues preventing systems HFE from realizing its full impact. There is a research–practice gap, a lack of reliability and validity evidence associated with systems HFE methods, and a shortage of methods that can predict behavior. In this article we revisit each issue, with each co-author providing their own perspective on the extent and causes of each issue, and their resolution. The perspectives reveal a consensus that the issues exist and are problematic but are challenging, multi-factorial, and require various solutions. The findings are subsequently synthesized to form an agenda for the wider discipline.
