characteristics of an effective vision

For the past few years, I've been trying to get my head around what it means to cast vision, what vision is, and its importance to leadership within a church. Last night I read Chapter 5 of Leading Change, which is about "Developing Vision and Strategy." I found it very helpful. On page 72, Kotter gives these "Characteristics of an Effective Vision."

>Imaginable: Conveys a picture of what the future will look like
>Desirable: Appeals to the long-term interests of employees, customers, stockholders, and others who have a stake in the enterprise
>Feasible: Comprises realistic, attainable goals
>Focused: Is clear enough to provide guidance in decision making
>Flexible: Is general enough to allow individual initiative and alternative responses in light of changing conditions
>Communicable: Is easy to communicate; can be successfully explained within five minutes
