What are McDonald external influences?

If you are asking what influences the McDonald's Corporation, a very major one would be cultural. McDonald's adapts their menu offerings according to the country where they are located. They also vary their menu by the region where they are located. The Demographics of an area would also influence the choice of employees, menu offerings, seating arrangements, restroom amenities, and the hours of business. For instance, a McDonald's located in an area that is primarily elderly adults might have more handicapped stalls in the restroom, more handicapped parking spots, and may not be open as late.
