Many people mistake vision statement for mission statement, and sometimes one is simply used as a longer term version of the other. The Vision should describe why it is important to achieve the Mission. A Vision statement defines the purpose or broader goal for being in existence or in the business and can remain the same for decades if crafted well. A Mission statement is more specific to what the enterprise can achieve itself. Vision should describe what will be achieved in the wider sphere if the organization and others are successful in achieving their individual missions.
