A supply chain management system is best described as which of the following?

• A. Manages internal IT infrastructure and help desk requests.
• B. Handles distribution and transportation of materials across the supply chain and often connects suppliers and distributors.
• C. Provides web portals for internal employees to access documents.
• D. Performs accounting and payroll processing.

Answer: (B)

The main idea is that a supply chain management system coordinates the flow of goods, information, and finances across the entire chain, linking suppliers, manufacturers, distributors, and retailers to plan, execute, and optimize distribution and transportation. This description fits because SCM systems are built to manage how materials move from suppliers to warehouses to customers, synchronize demand and supply, and improve visibility and efficiency across the network. They often integrate logistics planning, order fulfillment, inventory management, and supplier coordination, sometimes tying into ERP or warehouse systems to streamline operations.

It’s not about internal IT help desks, web portals for documents, or payroll and accounting—those describe IT service management, intranet/document access, or financial management, respectively, rather than the networked orchestration of materials and shipments across a supply chain.
