What name did McDonald’s use for its early standardized restaurant production method?

McDonald’s called its early standardized restaurant production method the Speedee Service System.

The system was developed by Richard and Maurice McDonald at their San Bernardino, California, restaurant. It applied assembly-line principles to food preparation, reducing the menu and assigning workers specialized tasks. The approach helped make service faster and more consistent.

The Speedee name also appeared in McDonald’s early branding through the company’s chef-hat mascot. This connection explains why Speedee was an important symbol before the Golden Arches became the dominant visual mark.

The system is sometimes described simply as fast food, but that phrase is broader. The Speedee Service System specifically refers to the McDonald brothers’ organized, standardized operating model that influenced the modern fast-food format.
