 The experimental design was to simulate an air defense control center in which the team was presented with simulated radar images showing air traffic as well as simulated telephone conversations with outside agencies reporting additional information (such as the availability of interceptor aircraft or confirmation of civilian aircraft).The experiment series generated a great deal of both qualitative and quantitative data and the results of earlier experiments were used to improve the experimental apparatus and organization for later versions of the experiment.The first experiment ("Casey") was conducted with college students from which it was determined that culture was a large factor in team as well as individual performance.
