What name did McDonald’s use for its quick-service operating system introduced by the McDonald brothers in 1948?

The McDonald brothers introduced the Speedee Service System in 1948 as McDonald’s quick-service operating model.

Richard and Maurice McDonald redesigned their San Bernardino, California, restaurant around speed, limited choice, low prices, and standardized preparation. The system reduced dependence on traditional carhop service and made it possible to serve large numbers of customers efficiently.

The name Speedee was also represented by an early chef mascot, a smiling figure associated with the restaurant before the Golden Arches became the dominant visual symbol. This creates a frequent mix-up: Speedee Service System describes the operating method, while Speedee was also the name used for the early mascot.

The system became a foundation for modern fast-food franchising. Ray Kroc later built McDonald’s national expansion around consistent procedures, restaurant design, training, and branding derived from the McDonald brothers’ original approach.
