I thought this was the guiding principle of the park:
The World you have entered was created by The Walt Disney Company and is dedicated to Hollywood—not a place on a map, but a state of mind that exists wherever people dream and wonder and imagine, a place where illusion and reality are fused by technological magic. We welcome you to a Hollywood that never was—and always will be.”
Does the park actually have a mission and vision statement that differs from the dedication?
Guiding principles are actually more like rules that you can't break if you want to be successful. They're things like this:
* My business will always provide excellent customer service and resolve all problems within one work day.
* My employees will answer all emails within one hour from 8am to 4pm M-F.
* Every customer who comes through the door will be greeted with a smile.
Those are basic guiding principles. For DHS these could be:
* DHS will provide highly immersive, themed areas that make guests feel they are in the movies.
* DHS will have no fewer than 5 popular E-ticket rides and at least 15 rides total that people clamor to get on.
* DHS will rise above the competition by maintaing all its attractions and themed areas to the highest industry standards of upkeep.
So, guiding principles are very nuts and bolts. Mission Statements are the more flowery things...and Vision Statements are like gardens of flowers. A Mission Statement is typically one sentence (two max) and the Vision Statement can be more of a paragraph.
The dedication for DHS that you quoted could be seen as a Vision Statement, but unless TDO has specified that's what their VS was I would not assume it's what they've been using. Chances are it was put on that plaque and forgotten about.
Mission statements, visions statements, and guiding principles were drilled into people in the 90s and early 2000s and I read a lot of business books and took a lot of seminars on this stuff. It's part of my DNA now but I don't know if people just starting business careers or going to school now are even taught this stuff.
I've had my own business for about 30 years now and this is what I use to run it so it works for me. I taught my son and daughter to do it and now I teach my niece and nephew because I think it's a great way to keep whatever you are doing from going off the rails and losing your focus.
Like how DHS has gone off the rails and lost its focus...but it is certainly salvageable.
