Concept of Vision in an Organisation

A Vision is a clear and succinct description of realistic, credible, attractive future what the organization or community should look like after it successfully implements its strategies and achieves its full potential. It is an expression by the people about what they want the organization to be – a preferred future, a word or picture of an organization you choose to create. Here’s an example -
Amazon - Our vision is to be earth's most customer centric company; to build a place where people can come to find and discover anything they might want to buy online.

Explanation of parts of vision
Realistic - a vision must be grounded in reality to be eloquent for an organization. For example, if an organization is evolving a vision for a computer software company that has carved out a small niche in the market developing instructional software and has a 1.5 present share of the computer software market, a vision to overtake Microsoft and dominate the software market is not realistic.
Credible - a vision must be plausible to be relevant; most importantly, to the employees or members of the organization. If the members of the organization do not find the vision credible, it will not be meaningful or serve a useful purpose. One of the purposes of a vision is to inspire those in the organization to achieve a level of excellence, and to provide purpose and direction for the work of those employees. A vision which is not credible will accomplish neither of these ends.
Attractive - a vision should be inspiring and motivating employees or members of the organization, it must be attractive. People must want to be part of this future that's envisioned for the organization.
Future - a vision is not in the present, it is in the future. It is not where you are now; it's where you want to be in the future. If the vision is attained, and it's no longer in the future, but in the present, is it still a vision.
