There are fundamental differences between these two concepts, despite often finding that the terms are used interchangeably. Human Factors (and ergonomics) represents a science, discipline, and a profession (CIEHF). It is concerned with optimising human well-being and overall system performance through understanding human interaction, by applying theory, principles, data, and methods (International Ergonomics Association).
It’s reasonable to suggest that TRM, with its roots in Crew Resource Management which is used in the aviation industry, to be an element of the HF and ergonomic discipline. However, it is not the ‘only’ element! TRM seeks to provide individuals with processes, styles and methods to improve team behaviours, decision making and task completion – however, it should not be used in isolation to cover up or ignore system related challenges, and disruptions.
