Turner had previously been the assistant CIO under Mott. As the CIO of Walmart, Turner oversaw Walmart's information technology and worldwide data-tracking system. The division consisted of over 2,000 employees in Bentonville, Arkansas. He led the team that developed retail-specific applications such as Retail Link at Walmart. During his tenure, Turner was one of the world's largest corporate buyers of technology, and directed the technology strategy of a company renowned for its deft use of computing to streamline everything from global procurement to neighborhood shopping trends. CEO of Sam's Club (2002–2005) In 2002, Turner replaced Tom Grimm as the president and chief executive officer of the Walmart-owned retailer Sam's Club, which had over 46 million members and over US$37.1 billion in annual sales. In addition to his role at Sam's Club, he was also a member of the executive committee at Walmart. Under Turner, Sam's Club focused on lowering prices to win over small-business customers. In his last fiscal year as CEO, Sam's Club turned in a 5.8 percent sales growth at stores open at least a year, which was nearly double the 2.9 percent sales growth at U.S. Walmart stores. During his tenure as CEO, Turner improved the performance of the warehouse clubs and closed the gap with Costco. Turner was the president and CEO of Sam's Club until he left for Microsoft in 2005. After his departure for Microsoft, Sam's Club named Doug McMillon as its CEO. COO of Microsoft (2005–2016) In 2005, Turner was approached by Microsoft co-founder Bill Gates and CEO Steve Ballmer about overseeing the company's worldwide sales, marketing, services, and internal IT operations organization. He had previously worked with Gates and Ballmer during his time as CIO of Walmart. Turner accepted the offer and moved his wife and three children to Washington State where, in September 2005, he became the chief operating officer of Microsoft (the previous COO, Rick Belluzzo, had left the company in 2002 and no replacement had been hired). From 2005 to 2016, Turner was responsible for the strategic and operational leadership of Microsoft's worldwide sales, field marketing and services organization. He also managed support and partner channels, Microsoft stores, and corporate support functions including information technology, licensing and pricing, and operations. His organization included over 70,000 employees in more than 190 countries. In 2009, Turner started Microsoft's entry into the retail stores business. Along with Steve Ballmer, Satya Nadella and
