The purpose of the study was to investigate general methods in order to describe and measure decision making. Furthermore, to investigate whether the decision task was interpreted as dynamic. In order to make this possible both a method and a measure of description were tested, which could be used in following studies to elucidate differences after training of the decision making process. The basis of the study is theories about dynamic decision making, mainly from Brehmer and Dörner. The study was performed with battalion commanders and rescue leaders training in a commander´s training centre, and with chairmen of the city executive board under similar conditions. The results of this study show that the decision task is dynamic, that the method can describe dynamic decision making, and that the results are a foundation for the next study. The aim of the subsequent research is to give a foundation for valuation of decision making training in dynamic situations by means of micro worlds.
