Cast study: Motivating cast members at Disney

The Walt Disney Company started out in 1923 as a small animation studio. In the decades since then, the company has grown to become the largest entertainment business in the world.

One of Disney's hallmarks is legendary customer service, especially at its theme parks and on its cruise ships. Theme Park employees are called "cast members" and are taught that the ultimate goal is guest happiness and that no matter what role they play, they are expected to smile, project a positive image and be friendly.

Disney wants to motivate its cast members.

Do you have any suggestions or advice on how to motivate the cast members?
