Sales managers need information from a marketing information system to monitor product performance, plan sales force activities, and make pricing decisions. A marketing information system gathers, analyzes, and distributes pertinent data to marketing decision makers to improve planning, implementation, and control. It provides information on sales, revenues, costs, and growth for specific products, product lines, and brands. Channel systems support sales and distribution operations while supply chain management systems provide end-to-end visibility across the entire supply chain.
