Change leadership is not change management

Dr John Kotter speaks about the significant difference between "change leadership" and "change management". 

Change management involves processes to control and contain change whereas change leadership is "putting an engine on the whole change process". and creating transformation. Change leadership allows for the messiness of change and harnesses the energy of people to innovate, solve complex problems and make a difference in the world in unexpected ways.

Kotter asserts that change leadership is a skill that is largely missing in the world.  Maybe this partly explains why attempts at transformation so often fail.
