The SPIRIT system is the first State Agency Model (SAM) developed after an initiative by the U.S. Department of Agriculture Food and Nutrition Service (USDA/FNS)—as directed by the Office of Management and Budget (OMB)—to plan, develop and deploy model management information systems to support WIC State Agencies (SAs).

Recognized as permanent in 1974, the Women, Infants, and Children program was established to safeguard the health of low-income women, infants and children up to age 5 who are at nutrition risk.
Information systems are the heart of effective administration of the U.S. Department of Agriculture/Food and Nutrition Service (USDA/FNS) Supplemental Food Program for Women, Infants and Children (WIC). In 2002, 13 Indian Tribal Organizations (ITOs) in the southwest region of the United States formed a consortium to support the next generation of automation for clinic operations and State agency administration of the WIC.
The SAM project is created on the philosophy of "Build it once and replicate it many times."
