Jannatul Sadia presented on supply chain management. She defined SCM as coordinating supply activities from suppliers to customers. A supply chain typically involves raw material producers, manufacturers, and retailers. SCM aims to transform raw materials into final products through upstream and downstream processes. Benefits include improved customer service and costs savings, while challenges involve lack of visibility and meeting delivery times. SCM can be viewed as acquiring inputs, transforming them into outputs, and delivering products and services to fulfill customer needs and increase profits.
