The purpose of this study was to concretize how a net-work based decision process might be manifested in 2020. Four theories on decision making deriving from the behavioral sciences and two from organizational theory were compiled into one decision model. The model describes the choice of method for decision making among three different alternatives to generate commanders intent: rational, rapid and negotiated decisions. The model also describes the management of progressing tasks. The final implementation of the decision is regarded as an administrative task. The model also specifies the necessity to organize a temporary command and control function if the task calls for the coordination of different reciprocally independent organizations. Using the model as a script, two war gaming sessions were conducted. The consequences on technical decision support systems, decision-making methods and organisational solutions were discussed in the context of two different scenarios. Further developments of formalised decision methods are judged to be an important issue. Focus of such a development should be adaptation to international operations.
