What was McDonald's original 1948 restaurant service system called?

McDonald's original 1948 restaurant service system was called the Speedee Service System.

Richard and Maurice McDonald introduced the system when they reorganized their San Bernardino, California, restaurant around speed, consistency, and a limited menu. Instead of operating like a traditional drive-in with many made-to-order options, the brothers emphasized standardized preparation and efficient assembly.

The system helped establish ideas that later became central to fast food: specialized workstations, a restricted menu, self-service elements, and predictable portions. Its name also explains the early use of Speedee as a brand character.

Ray Kroc later recognized the potential of the brothers' operating model and helped expand McDonald's through franchising. The Speedee Service System is therefore not simply an old slogan; it was an operational and branding foundation for the modern chain. It predates the Golden Arches logo and the later McDonaldland characters.
