ABSTRACT
Research into decision making has traditionally focused on how people – as individuals – choose among alternatives and specifically about how they go about finding the best alternative or making the right decisions. The assumptions of the homo economicus refer to the nature of decision making as a process, as something that takes place in the mind of the individual decision maker. It is a consequence of changing the view of decision making from being a separate process to being a facet of work and of acknowledging the paramount importance of time that the three assumptions implied by rational decision making are no longer tenable. Decision making in the traditional sense can be seen as the interface between the evaluation of the situation and the choice of action, or perhaps as a combination. Changing the view of decision making from focusing on what to focusing on how also changes the issue of decision support completely.
