What name did McDonald’s use for its service system when the company was founded in 1948?

McDonald’s used the name Speedee Service System for the restaurant service model introduced by Richard and Maurice McDonald in 1948.

The system reorganized hamburger preparation around a limited menu, standardized procedures, and assembly-line production. This approach reduced waiting time and helped the restaurant serve food more consistently. It became an important foundation for the fast-food format later expanded through franchising.

Speedee was also represented by an early chef-like mascot, which can cause confusion with the service system itself. The mascot and the operating method shared the Speedee name, but they were different parts of the brand. Ray Kroc later expanded the business nationally, while the original brothers’ system supplied the operational model that made large-scale consistency possible.
