Brenau University President Ed Schrader joined Tumblr founder David Karp and others on a panel Friday addressing the usefulness of master of business administration programs. The panel was part of the Let’s Get Real Conference in New York City, a daylong symposium sponsored by Brenau and the Atlanta-based Oxford Center for Entrepreneurs. Schrader called for an “academic shake-up” during the symposium, saying leaders should explore individually customized programs that have been “unbundled” from traditional college degree tracks.
