The document discusses how information technology (IT) can enhance supply chain management efficiency at IBM. IT applications like e-procurement, e-catalogues, e-marketplaces, and e-auctions can improve efficiency, speed, accuracy, and cost optimization. These applications allow electronic purchasing, provide product information online, enable suppliers to compete for buyers' business, and facilitate online payments. If implemented properly across IBM's supply chain, such IT solutions have the potential to significantly increase supply chain management efficiency through lower costs, faster processes, and greater compliance.
