Supply chain management (SCM) is the process of overseeing the flow of goods and services from producer to consumer, encompassing everything from raw material acquisition to product delivery. Effective SCM enables companies to reduce costs and improve efficiency while maximizing customer value, ultimately maintaining profitability and minimizing risks. Notable examples of successful SCM include Walmart and Procter & Gamble's collaboration, as well as Walgreens' investment in technology to streamline inventory management.
