Tremblay, 53, most recently was North America Manufacturing vice president.
GM is creating an all-new Global Business Services group that it claims will streamline back-office processes to improve service quality, reduce complexity and cut costs. Diana Tremblay, a GM lifer, is the Global Business Services vice president and will report to Dan Ammann, GM senior vice president and chief financial officer.
Tremblay’s appointment is effective 1 July 1. Her workers will come from employees in Finance, Human Resources, Facilities, Real Estate and Indirect Purchasing. 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% over the next four years. Whether the cost savings come from eliminating jobs was not immediately clear.
Tremblay, 53, most recently was North America Manufacturing vice president. Her 36-year GM career includes 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.
“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.
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.
