What phrase identified McDonald’s original service system and emphasized fast food preparation?

The phrase “Speedee Service System” identified McDonald’s original fast-food preparation system.

Richard and Maurice McDonald developed the system at their San Bernardino restaurant in 1948. They simplified the menu, standardized preparation, and organized the kitchen so food could be produced quickly and consistently.

The system was a foundational part of McDonald’s branding because the business name became associated with speed, predictability, and inexpensive meals. The early mascot Speedee took his name from this service concept.

The system is often confused with the later corporate franchise model associated with Ray Kroc. Kroc helped expand McDonald’s nationally, but the Speedee Service System was developed by the McDonald brothers before that expansion.
