GM Names Global Business Services Vice President


DETROIT – General Motors announced an all-new Global Business Services group that will streamline back-office processes to improve service quality, reduce complexity, and achieve cost efficiencies. Diana Tremblay is named Global Business Services vice president and will report to Dan Ammann, GM senior vice president and chief financial officer. 

Tremblay’s appointment is effective July 1, and her team, composed initially of certain groups of employees from finance, human resources, facilities, real estate, and indirect purchasing, will begin implementation immediately. When fully operational, Global Business Services will manage dozens of common processes across GM and include thousands of employees across the globe. The group is expected to reduce associated costs by at least 30 percent over the next four years.

“Every dollar of efficiency unlocked through Global Business Services is a dollar we can put back into our vehicles for our customers or is a dollar we can take to the bottom line,” Ammann said. “Diana’s proven leadership, creative problem-solving, relationship-building and tenacity make her the right leader for this crucial effort.”

Tremblay, 53, most recently was North America Manufacturing vice president. Her 36-year GM career includes key leadership roles in labor relations and manufacturing, including positions in Luton, England, and Antwerp, Belgium. As GM North America vice president of labor relations, she led the team that negotiated the 2007 UAW-GM agreement. 

Tremblay holds a Bachelor of Science in industrial administration from Kettering University and a Master of Science in management from the Massachusetts Institute of Technology. She is on the board of directors for Focus: HOPE and Medical Advantage Group, and a member of the Kettering University board of trustees. She also serves as executive champion for GM’s African Ancestry Network.
