Days after firing Henderson, and leaving Lutz with an advisory role with no reports, Whitacre who is now the CEO has moved to bring younger managers in important positions. Mark Reuss assumes the role of head of the North American operations. One year ago he was running the Australian operations. He was only recently in charge of engineering at GM. The Board is pushing for these changes. Whitacre says the GM culture and tendency for top managers not to bring in younger managers to run things has stifled talented younger people at the company. Susan Docherty was given additional responsibilities of marketing. Some of these moves were long overdue. The old echelons simply stayed on for too long risking the jobs of tens of thousands of GM workers and taking the company to the brink of disaster.
