What was the name of McDonald's early service system that emphasized fast, standardized food preparation?

The Speedee Service System was McDonald's early operating model for fast, standardized food preparation.

Richard and Maurice McDonald developed the system at their San Bernardino, California, restaurant after redesigning operations around a limited menu and an assembly-line approach. The method reduced waiting time and made food production more consistent.

Its name influenced early McDonald's branding, including the Speedee mascot. The emphasis was not simply on speed at the counter; it also involved organizing kitchen tasks, limiting choices, and producing popular items in a repeatable way.

The system became an important foundation for the McDonald's franchise model. It is sometimes confused with a slogan or a logo, but it was primarily an operational system whose ideas shaped both the company's restaurant design and its later brand identity.
