Revenue: $57.3 billion (up 3.6 percent)
Daniels has worldwide responsibility for IBM Global Services business operations in outsourcing services, integrated technology services, small and midsize business services, IBM Global Financing and for IBM's global delivery services. Together, those businesses account for almost half of IBM's revenue.
On IBM's Web site, Daniels notes that globalization is increasingly important for companies to survive and thrive.
"Globalization requires companies be part of a global supply chain, deal with worldwide labor supply and manage talent around the globe," according to Daniels. "Enterprises need the right tools, management processes and governance to explore new marketplaces, support customers, enable new levels of collaboration and expand their business operations. There is a tremendous convergence happening in the areas of voice, video, data and mobility and application resources."
