SCOR is a supply chain operations reference model developed to help businesses understand, structure, and evaluate supply chain performance. It was created by the Supply Chain Council, an independent nonprofit, and is used as a cross-industry standard. SCOR describes supply chains using standardized processes, metrics, and best practices applicable to companies of varying complexity. It evaluates supply chain operations at three levels: process types, categories, and elements. The model can be implemented by companies like Iranol Oil to measure, manage, and improve their planning, sourcing, production, and delivery processes.
