Management is a practice... Peter Drucker Management is a practice, like medicine; and the model should have been the medical school, where the bulk of the teaching, especially the most important teaching of the M.D. in his or her residency, is performed by practitioners. Unlike medicine, where you can bring sick patients into the classroom, business education does not allow you to bring an organization into the classroom. You can, however, bring experience in through your faculty and students. Business educators should be out as practitioners where the problems and results are.
