Primary force behind successful change?

Leadership is different from management, and the primary force behind successful change of any significance is the former, not the latter. Without sufficient leadership, the probability of mistakes increases greatly and the probability of success decreases accordingly. This is true no matter how the change is conceptualised—that is, in terms of new strategies, reengineering, acquisitions, restructuring, quality programs, cultural redesign, and so on. Because the rate of change is increasing, leadership is a growing part of managerial work. Far too many people in positions of power still fail to recognize or acknowledge this most important observation. What do you think?
