What was the name of McDonald's standardized service system introduced by the McDonald brothers in 1948?

The McDonald brothers’ standardized service system, introduced in 1948, was called the Speedee Service System.

The system reorganized restaurant work around a limited menu, assembly-line preparation, and consistent portions. Instead of operating mainly as a carhop drive-in, the San Bernardino restaurant focused on producing hamburgers, fries, milkshakes, and drinks quickly and predictably.

The name connected the system to Speedee, an early McDonald’s mascot represented by a chef-like character. Speedee symbolized speed and efficiency before Ronald McDonald became the company’s best-known character. The system’s principles later became central to McDonald’s franchise training and branding.

People sometimes confuse Speedee Service System with a mascot name, but they are not the same thing. Speedee was the character; the Speedee Service System was the operating method. The distinction matters because McDonald’s branding history grew directly from the restaurant’s promise of fast, uniform service.
