We can predict that the structure of Carnival Cruises will be much more bureaucratized than the structure of the other cruise line.
In the scenario you provide, Carnival is much more of a mass merchandiser. It handles huge volumes of customers. This means that Carnival will need much more of a bureaucracy. Carnival will also be less attuned to the idea of providing truly superior service. It has to be more concerned with maintaining a smoothly functioning company. It is too big to be able to be personalized. Once again, this leads to a more bureaucratized and formal structure than that of the boutique line. The smaller line will have a structure that emphasizes flexibility and providing customers with exactly what they want.
