What was the name of McDonald's streamlined operating system introduced in 1948?

McDonald's streamlined operating system introduced in 1948 was called the Speedee Service System.

Richard and Maurice McDonald created the system when they rebuilt their San Bernardino restaurant around speed, consistency, and a sharply reduced menu. Instead of relying on carhops and a large selection of barbecue dishes, the restaurant used standardized preparation and assembly-line methods for hamburgers, fries, and drinks.

The word “Speedee” also became an early McDonald's character and visual symbol. It was represented as a small chef-like figure and helped communicate the restaurant's promise of fast service. The system's name therefore connected operations with branding in a way that made the business model easy for customers to understand.

Ray Kroc later recognized the commercial potential of the McDonald brothers' approach. His franchise expansion retained the emphasis on uniform procedures, which became central to McDonald's worldwide identity. Speedee is often confused with later characters such as Ronald McDonald, but they belonged to different stages of the company's branding history.
