Simulation-based decision support is a holistic methodology for decision assessment in organizations. System dynamics is a proper methodology for modeling and testing the dynamic hypotheses of organizational systems. The role of subjects in model development and its validation from cybernetic, psychological and cognitive perspectives are discussed in this paper. Group participation in model building and validation is suggested in order to prevent the manipulation of dominant subjects and/or implicit dictators during modeling. This paper concludes with some useful examples of systems simulation in solving real problems.
