Migration of control in decision making organizations

In a distributed decision making organization supported by information processing and decision aiding systems, it is not always apparent whose decision affects the outcome the most. Often, control migrates away from the designated organization member in unexpected wasy depending on the decisions of individual decision makers, on the structure of the organization, and on its operating procedures. A mathematical formulation of the concept of migration of control and of regions of dominance is given; the model and the computational procedure are illustrated by two simple examples. The point is made that the introduction of technologies that allow distributed decision making brings into focus dynamic phenomena that need novel approaches and new concepts to describe them.
