Every functional area in a Marriott Hotel operates under standard operating procedure manuals where all processes and services are carefully documented. Housekeepers, for example, must perform $64$ required steps in cleaning a room. These specific guidelines result in uniformly clean rooms anywhere in the Marriott Hotel chain. By having specific guidelines for cleaning a room, Marriott is avoiding one of the problems associated with:

Inadequate management of service promises

Over$-$promising in advertising and personal selling

Inadequate external marketing communication

Inadequate interactive marketing communications

Inadequate internal marketing communications
