Supply chain management (SCM) systems help companies manage key business processes like suppliers, customers, and partners. SCM involves planning production and delivery, sourcing materials, manufacturing products, and returning unsatisfactory goods. The goals of SCM are speed, efficiency, reduced costs, and improved cycle times. SCM systems have evolved from inventory software in the 1960s to today's technologically advanced systems that help with forecasting, logistics, predictability, and reducing costs. While ERP integrates all business functions, SCM is more specialized in planning and executing the supply chain.
