Walmart has dominated the retail industry through strategic supply chain management and low prices. It employs over 1.8 million people worldwide and has over 11,000 stores across 27 countries. Key to its success has been cross-docking inventory and using technology to efficiently transfer goods between suppliers and stores with little warehousing. Initiatives like global sourcing and RFID tracking have further optimized Walmart's supply chain. To remain competitive, it will need to continue innovating, like improving its online presence against Amazon.
