Planned organizational change processes are of increasing need for organizations to maintain their competitive edge in today's global economy. Yet planned change efforts have been documented to have failure rates between 50-70 percent. Thus management skills and training in successful change processes is of high value. This article provides a critical review of organizational change models existing in the literature. Eleven literature change models were combined into a consolidated model of organizational change to identify the consistency in current research on this topic. The models were also analyzed according to their implementation (or lack thereof) into real-time change processes as well as documentation of performance information validating their success. Based upon these initial findings, areas of opportunity are identified to guide future research efforts towards improving the processes for planning and implementing organizational change.
