The Retail Industry Business Reference Architecture provides a unified, end‑to‑end view that clarifies how value is created across the entire retail value chain. It cuts through the industry’s complexity by defining stable business capabilities and exposing the systems, data flows, and dependencies that enable them. This architecture matters because retail operations span stores, digital channels, distribution centers, suppliers, and customers, making alignment between IT, operational teams, and business functions difficult. By offering a common language and integrated view, it helps leaders reduce duplication, strengthen integration, and link technology investments directly to operational outcomes.
