What was the name of McDonald’s original 1948 service method that inspired its early branding?

McDonald’s original 1948 service method was called the Speedee Service System.

Richard and Maurice McDonald developed the system when they redesigned their San Bernardino restaurant around speed, consistency, and a limited menu. Instead of preparing many different foods to order, the restaurant organized work in a carefully divided production line.

Hamburgers, fries, and drinks could be assembled rapidly because each task was standardized. This operating idea became one of the foundations of the modern fast-food restaurant and influenced the way McDonald’s later trained franchisees.

The system also explains the importance of Speedee, the company’s early mascot. The name and character were direct branding expressions of the restaurant’s service promise. It should not be confused with later corporate slogans, which promoted feelings or convenience rather than describing the operating method itself.
