Chance serves as the gate to organizational change. Based on a relational view of chance, we propose that in an organizational context, the chance to change is affected by the perceptions of change agents and the affordance of situational momentum, and that different time points of change are associated with different degrees of chance favorability. We develop a theoretical model to represent how change agents can assess the favorability of current and future momentum and how they can benefit from identifying a perceived chance by employing chance grasping, entraining, creating, or riding strategy to promote organizational change. We generate theoretical propositions to illustrate the four timing strategies of chance management. The overall contribution of this study is a chance management view of organizational change that considers change agents and situational momentum as two interdependent factors in the process of managing the chance to change.
