This document discusses the importance of vision for leadership. It defines vision as a mental model of an ideal future state that implies change and challenges people. An effective vision has five key characteristics: it presents a picture of a better future, represents a change from the status quo, is grounded in shared values, provides a map and direction, and presents an inspiring challenge. The leader must articulate the vision using inclusive language and serve as a living model, setting high expectations and empowering others to work towards the goals of the vision.
