There are various views about the role a leader should play in the change process (Leadership linked to organizational metaphors ):
The machine metaphor implies that the leader sits at the top of the organization, setting goals and driving them through to completion.
The political system metaphor implies that the leader needs to become the figure-head of a powerful coalition which attracts followers by communicating a compelling and attractive vision, and through negotiation and bargaining.
The organism metaphor says the leader’s primary role is that of coach, counsellor and consultant.
The flux and transformation metaphor says the leader is a facilitator of emergent change.
How does the leader of a change process ensure that all the necessary roles are carried out? Should the leader try to perform all these roles personally, or select a specific role for him or herself and distribute supporting roles amongst his or her colleagues?
