CASE STUDY 6-1 Data Communication at Walmart > FINANCE TECHNOLOGY IN SOCIETY | APPLICATION Walmart > Save money. Live better Walmart has made several changes in its data communica- tion systems to improve its suppliers' access to sales and inventory data. For example, the company added a cus- tomized Web site for its suppliers, such as Mattel, Procter & Gamble, and Warner-Lambert. Walmart's goal is to improve efficiency in order to keep prices low and maintain a high level of customer service. With Walmart's network, suppli- ers can access sales, inventory, and forecasting data over extremely fast connections. To ensure confidentiality of data, a sophisticated security system has been imple- mented to prevent suppliers from accessing data about one another's products. Walmart has also added Web-based access to its RetailLink system so suppliers can use information in the database. Other data communication applications at Walmart include automated distribution, computerized routing, and electronic data interchange (EDI).29,30 Walmart uses the latest in wireless technology in its operations for warehouse management systems to track and manage the flow of goods through its distribution Vdovichenko Denis/Shutterstock.com centers. Another application of wireless technology is for controlling and monitoring forklifts and industrial vehicles that move merchandise inside its distribution centers. The Vehicle Management System (VMS) is the latest applica- tion of data communication at Walmart. Among other fea- tures, the VMS includes a two-way text messaging system that enables management to effectively divert material- handling resources to where they are needed the most. (The VMS works effectively with RFID-based systems.) According to Walmart, the VMS has improved safety and has also sig- nificantly improved the productivity of its operations."
