2. Channel Leadership Changes Dell EMC President of Global Channels John Byrne, the executive credited by partners with playing a critical role in integrating the Dell and EMC partner programs following Dell's landmark, $58 billion acquisition of EMC, took a new job at the company in late November as head of the company's North America commercial sales organization. Joyce Mullen (pictured), an 18-year Dell veteran took Byrne's place atop the company's $43 billion global channel business. Mullen was previously senior vice president of OEM and Internet of Things solutions, and her new title combines the two roles, making her president of global channels, OEM and IoT solutions.
