The Manager:   While competent and efficient managers are a necessary component of organizations there are some significant limitations to this style of leadership.  Managerial leaders solve problems in a top down manner.  They make decisions unilaterally. Their focus is on"us", the group they manage so they tend to get territorial.  Many of today's organizational problems cross   boundaries and need leaders who don't simply consider the impacts of changes on their discrete group.   The manager leadership style has a narrow perspective on interests.

The Mediator:  Gerzon proposes that our future crop of leaders will have the characteristics of a mediator.  Unlike the manager mindset, the mediator strives to act on behalf of the larger group, thinks broadly and systemically about problems and looks to build bridges across any divides.  Gerzon identifies these tools as follows:  integral vision, systems thinking, presence, inquiry, conscious conversation, dialogue, bridging and innovation.   While these tools are not steps in the mediation process  they are characteristics that mediators inherently possess in their heart and soul or develop through the process of peacemaking.
