Leading Change Processes for Success: A Dynamic Application of Diagnostic and Dialogic Organization Development

Abstract

Change processes, the activities that enable change, and change leadership, meaning how to lead change processes, both influence the success of change. However, a surprising omission from this knowledge is: how do leaders choose between change processes? This article explores leaders’ choices between two orientations of change processes—illustrated by dialogic and diagnostic organizational development—in 79 cases of organizational change. It identifies that change is successful when leaders choose to oscillate between these two processes as change unfolds. Developing a model that explains this evolution, the article describes how the change leadership practice of concurrent inquiry interacts with the two representations of knowledge described by diagnostic and dialogic theories to inform a choice to oscillate. For scholars, this model further integrates the theoretical perspectives of dialogic and diagnostic theories. For practitioners, it provides a means to navigate between extant theories and, as such, ameliorate outcomes.
