This paper describes a new method for analyzing emergent organizational behaviors, which are causes of innovation and deviation phenomena, through an agent based
model and a case design. Organizational deviation is inextricably linked to innovation, because their mechanisms are similar in terms of breaking operational standards. We
have assumed that the former and the latter are different in external utilities, and under this assumption, we have developed a unified agent based model. The agent base
simulations have been conducted based on the model, for analyzing the emergence process of innovation and deviation. The simulation results have been compared with case analysis
in order to obtain an in-depth understanding of inextricably linked organizational phenomena, and to distinguish the similarities and differences between innovation and deviation.
