Whenever I interact with my peers in the legal community, I often get asked the same two questions related to Walmart: How do we manage the size of our company—2.3 million associates, over 260 million customer transactions per week and more than 11,700 stores—and how does technology help a company the size of Walmart to manage risk across 28 countries?

While technology is a key differentiator of our compliance program compared with other global companies, the bedrock of our program has always been strong leadership. In a word, our program works because of our culture. Good systems, design and processes are critical, but people are the foundation.
