Since the formation of the primary basis of the management in organizations and the formation of the governance of organizational bureaucracies until now with the goal of increasing production efficiency, various theories have been provided under the influence of different scientific paradigms. At the beginning of the 20th century two important paradigms i.e. Newton paradigm and chaos paradigm seriously influenced all organizational theories and patterns. In classic theories of order, stability and consistency were considered as organization’s inseparable features. In organic theories an organization becomes ill or sick like a live organ; so for cure it some changes must be made. Among these theories complex system and chaos theory is the basis of another paradigm which in addition to management area has affected other scientific areas by itself. The Complexity theory has this massage for the managers that the time of managing with the use of hierarchical (predetermined) goals or predetermined logic and precise controlling is over. Systems are continuously moving between different attractions (dynamic balance) in chaos and disorder conditions and sometimes a small change results in vast and basic changes in the system. For change management in complex and chaotic system, traditional methods are no more applicable and managers should learn the changes in these systems.
