Contribution à l'analyse du comportement du décideur face aux systèmes d'aide à la décision : application aux salles de marchés

Abstract : What is the behaviour of decision makers in front of Decision Support Systems? Which are the factors explaining the use of such systems? To answer these questions, the research work tries to describe the decision makers' usage practices of Management Information Systems and proposes to contribute to the knowledge of the factors explaining the behaviour of decision makers towards Management Information Systems. After a recall of the notions related to decision oriented Management Information Systems, decisions and decision makers, a synthesis of factors influencing the relations between decision makers and Decision Support Systems is proposed. A conceptual model is then developed, in a iterative form, founded on various theories. An analysis of the decision makers' behaviour relative to Management Information Systems is then carried out. Empirically, this analysis is carried out through a qualitative and exploratory study of trading rooms on one hand, and, on the other hand, through a quantitative complementary study within the same inquiry environment. The study covers, successively, the operators working environment in terms on information systems, the decision making activity of these actors, their decision making process, their behaviour towards financial information systems and the impact of the quality (of the information systems themselves as well as the information) on their usage practices. The study concludes with the influence of the nature of the activity, the quality of the information systems and the availability of these systems on the behaviour of the end-users. The study ends with some considerations and proposals concerning the usage of decision-making information systems.
