What was the name of McDonald’s operating concept introduced after its 1948 redesign?

The operating concept introduced after McDonald’s 1948 redesign was the Speedee Service System.

Richard and Maurice McDonald developed the system after closing their San Bernardino drive-in and simplifying its operation. They reduced the menu, standardized preparation, used assembly-line methods, and emphasized fast counter service. The approach was inspired in part by industrial production and made the restaurant more efficient than a traditional drive-in.

The name connected the operating model with Speedee, the chain’s early mascot. It also helped communicate the central promise of the redesigned restaurant: customers could receive a limited selection of familiar foods quickly and consistently. This system became a foundation for the later franchise model.

The Speedee Service System was not the same thing as the Golden Arches. The arches identified the restaurant visually, while the service system described how it operated. Ray Kroc later helped expand and standardize the concept nationally, but the original redesign came from the McDonald brothers in 1948.
