ABSTRACT
When Klein (1989) first postulated that cue-utilization was a core component of expertise and diagnostic performance, his observations were predominantly drawn from interviews with fire commanders. At time of the interviews, one of the characteristics of this work-role was that decision-making was performed locally. This meant that many of the features available to the fire commanders occurred in real-time and were directly linked to important outcomes. However, increasingly we find that this type of diagnostic task is the exception rather than the rule.
