Abstract
This study focused on the importance of what the operating team successfully and adequately diagnosed and behaved during a plant abnormal condition. This paper developed a method for trial to evaluate the team faculties, referring to the findings from simulated experiment studies, studies on group psychology or group dynamics. This method divided the team faculties into three functions, “Direction and Orientation”, “Recovery” and “Maintenance of cooperation” to evaluate the team activity under simulated abnormal conditions. This paper also noted some applications of this method to the results of some simulated experiments. As a result, it was found that this method made clear the differences of the faculties depending on the situations or the teams. This also made clear some factors hindering the three functions from working, some characteristics of each team or some important factors to enhance the team faculties.
