What was the name of McDonald’s original streamlined restaurant service system?

McDonald’s original streamlined restaurant service system was called the Speedee Service System.

Richard and Maurice McDonald developed the system after redesigning their San Bernardino restaurant around speed, consistency, and a limited menu. Food preparation was organized more like an assembly line than a traditional drive-in restaurant, reducing waiting time and simplifying employee tasks.

The name connected the operating method to Speedee, the company’s early mascot. It is sometimes confused with the later McDonald’s brand itself, but the Speedee Service System was specifically the restaurant-production and service model.

This system became a foundation for modern fast food. Standardized portions, specialized workstations, and repeatable procedures allowed McDonald’s restaurants to deliver similar products quickly and helped the company scale through franchising.
