Hotel management is now a globally accepted career field and academic field of study. Degree programs such as hospitality management studies, a business degree or certification programs formally prepare hotel managers for industry practice. Hotel management refers to each and every staff member employed by a hotel to cater to the demands of its clientele. Hotel management varies by hotel size, function, and is often determined by hotel ownership. Small hotels usually have a small management while larger hotels may have a large management team consisting of managers of various departments and divisions. The size and magnitude of a hotel management structure varies significantly depending on the size and function of the hotel.
