What was the name of McDonald's streamlined service system introduced after its 1948 redesign?

McDonald's streamlined service system introduced after its 1948 redesign was called the Speedee Service System.

Richard and Maurice McDonald rebuilt their San Bernardino restaurant around speed, consistency, and a limited menu. They removed carhops, concentrated on hamburgers, fries, and beverages, and organized food preparation more like an assembly line. The system became a foundation of modern fast-food operations.

The name is related to the early Speedee mascot, but the two are not the same thing. Speedee Service System described the operating method, while Speedee was a character used in early McDonald's branding. The system also preceded Ray Kroc's arrival as a franchise entrepreneur in the 1950s.
