The organizational level includes both the formal and the informal organization. The formal organization involves the ways authority is distributed across various organizational levels and how organizational structure impacts the way activities in the organization are coordinated and controlled. The informal organization or the organizational culture can have a profound impact on the way both leaders and followers behaveand may be the least recognizable because it is the water in the bowl where all the fish are swimming. An important variable at the environmental level is societal culture, which involves learned behaviors that guide the distinctive mannerisms, ways of thinking, and values within societies.

Question:

What role do leaders play in creating a shared understanding of the situation a group, organization, or country faces? 

Is such a "shared understanding" or GAPS analysis even possible in a diverse society with countless and competing sources of information?
