To run IT like a business, one must proactively define valuable services for customers, understand how to fulfill those services through supply chains, track demand, identify all costs, benchmark performance and costs, and enable business intelligence capabilities. Key aspects include defining IT services, service requests, service catalogs, request fulfillment processes, service transitions to production, service level agreements, and continual service improvement through metrics. Running IT like a business centers on managing services, costs and performance across functional areas through a supply chain approach.
