Wayne State University's school of business consolidated its five separate departments into two: accounting and the department of business on Sept. 1. The new department of business includes the formerly separate areas of management, marketing, finance, and information systems/ manufacturing. The cost-saving move cut three chair positions and helped the university prepare for the possible addition of a doctoral program in business, said Thomas Naughton, associate chair of the Detroit-based university's department of business and director of its MBA program.
