Abstract
Recently organization is required innovative decision (or choice) more than before. Such kinds of decision can not emerge from bureaucratic or routinized decision making process. The most popular model for analyzing innovative decision is “organized anarchy model” such as “garbage can model”. This model stresses ambiguity within organization, random decision making process, export rationalization of decision content, and indifference of decision from intention or voluntariness of members within organization. Thus this model regards innovative decision as non-intended or accidental phenomenon. Innovative things surely have unintended or accidental aspects. But a kind of game is played on the base of members' voluntariness within the historical and concrete constraint of organization. In effect, if the field of decision making process is practically tried to be observed, the concrete historical structure of interest and power, which is constructed on formal or informal organizational structure, task flow and so on, forms the most of decisions through conflicts and negotiations by members' voluntariness. This political game is developed on the historical and institutional backgrounds of organization. The concept of the chance decision or the ambigorous process of organized anarchy model is thought to be the abstract and general analysis of the political game, and is to depict the caricature of the causality in decision process generally rather to explain each specific social process. Then “political power model” with the game concept is to be required, if decision making process is practically analyzed.
