Effective Supply Chain Management (SCM) is essential for any large international retailer. SCM is a complex discipline, drawing together elements of engineering, logistics, IT, and marketing to improve efficiencies and reduce costs. A well-managed supply chain is more dynamic and flexible, better able to meet the changing needs of consumers and the wider market. It can allow brands and retailers to optimize their prices, improve the allocation of their inventory, and identify potential problems at an early stage.
