What name did McDonald’s use for its original restaurant operating method introduced in 1948?

McDonald’s called its original restaurant operating method, introduced in 1948, the Speedee Service System.

Richard and Maurice McDonald developed the system at their San Bernardino restaurant after redesigning their business around speed, consistency, and a limited menu. The approach reduced waiting time and made food preparation more systematic than the earlier carhop model.

Its branding significance was substantial. The system supplied both a promise and a mascot: Speedee represented fast service, while the operating model helped create the repeatable customer experience that later franchise restaurants could reproduce.

The system is often described as an early foundation of modern fast food. Ray Kroc later expanded the McDonald’s business through franchising, but the operating concept came from the McDonald brothers. The name “Speedee Service System” therefore belongs to the pre-Kroc origins of McDonald’s branding and restaurant design.
