What name did McDonald's give its standardized operating method introduced by the original owners in 1948?

McDonald's called its standardized operating method the Speedee Service System.

Richard and Maurice McDonald introduced the system in 1948 after reorganizing their restaurant in San Bernardino, California. They reduced the menu, divided kitchen tasks, and designed preparation around speed and consistency. The approach helped establish the model later associated with modern fast food.

The system was more than a slogan: it was an operating and service concept. Customers ordered a limited range of inexpensive food, while specialized workstations allowed the restaurant to serve meals quickly. The name also inspired the early Speedee mascot.

Ray Kroc later expanded McDonald's through franchising, but the system originated with the McDonald brothers. It is therefore different from the later franchise business model and from the Golden Arches logo. The operating method supplied the foundation on which the brand's visual identity was built.
