What name did McDonald's use for its early production system focused on fast restaurant service?

McDonald's called its early fast-restaurant production method the Speedee Service System.

Richard and Maurice McDonald developed the system after redesigning their San Bernardino, California, restaurant in 1948. They reduced the menu, standardized preparation, and organized the kitchen so workers could produce food quickly and consistently.

The method was inspired partly by assembly-line production. Customers ordered at a counter rather than receiving traditional carhop service, and the limited menu made it easier to prepare popular items rapidly.

The system shaped both operations and branding. The name Speedee emphasized quick service, and it was also represented by the early Speedee mascot. Later McDonald's restaurants expanded the menu, but standardized procedures remained central to the franchise model.
