Consider your own current organization, or another with which you are familiar, which could be the institution where you are studying. Refer back to the description, from Collins and Porras (2005), of "The Complete Vision at Merck." Identify your chosen organization's vision in those terms: core ideology (and values), envisioned future, BHAGs, and vivid descriptions. Does your organization's vision help to drive change, or not? Why? Is the vision just a "public relations" exercise, or is it used in practice? How can you tell?
