Supply chain management (SCM) enhances business processes by managing the flow of materials and information from suppliers to customers, aiming to improve customer service and reduce costs. It includes various software modules and offers significant advantages, such as better relationships between buyers and suppliers, though it also faces challenges like high initial investment and integration difficulties. Recent software implementations, like Epicor 9 and Accuware's proactive inventory manager, demonstrate innovative approaches to streamline operations and enhance supplier performance.
