     Millions of people pass through the gate of Disney's entertainment parks in California, Florida, Paris and

Tokyo each year. What makes these places an almost universal attraction? What makes foreign kings and

queens and other important people want to visit these Disney parks? Well, one reason is the way they are

treated once they get there. The people at Disney go out of their way to serve their "guests", as they prefer to

call them and to see that they enjoy themselves.

     All new employees (雇员), from vice presidents to part-time workers, begin their employment by attending

Disney University and taking "Tradition I". Here, they learn about the company's history, how it is managed

and why it is successful. They are shown how each department relates to the whole. All employees are shown

how their part is important in making the whole part a success.

     After passing "Tradition I", the employees go on to more specialized training for their specific jobs. No

detail (细节) is missed. A simple job like taking tickets requires four eight-hour days of training. When one

ticket taker was asked why it took so much training for such a simple ordinary job, he replied, "What happens

if someone wants to know where the restrooms are, when the parade starts or what bus to take back to the

campgrounds? …We need to know the answers or where to get them quickly. Our constant aim is to help

our guests enjoy party." 

     Even Disney's managers get involved (参与) in the daily management of the park. Every year, the

managers leave their desks and business suits and put on special service clothes. For a full week, the bosses

sell hot dogs or ice cream, take tickets or drive the monorail, and take up any of the 100 jobs that make the

entertainment park come alive. The managers agree that this week helps them to see the company's goals more

clearly.

     All these efforts (努力) to serve the public well have made Walt Disney Productions famous. Disney is

considered by many as the best mass service (群体服务) provided in America or the world. As one long-time

business observer once said,"How Disney treats people, communicates with them, rewards them, is in my

view the very reason for his fifty years of success…I have watched, very carefully and with great respect

and admiration, the theory and practice of selling satisfaction and serving millions of people on a daily basis,

successfully. It is what Disney does best."
