To become a really effective vision statement, an organizational vision statement must (the theory states) become assimilated into the organization's culture. Leaders have the responsibility of communicating the vision regularly, creating narratives that illustrate the vision, acting as role-models by embodying the vision, creating short-term objectives compatible with the vision, and encouraging others to craft their own personal vision compatible with the organization's overall vision. In addition,
mission statements need to be subjected to an internal assessment and an external assessment. The internal assessment should focus on how members inside the organization interpret their mission statement. The external assessment — which includes all of the businesses stakeholders — is valuable since it offers a different perspective. These discrepancies between these two assessments can give insight on the organization's mission statement effectiveness.
