In response to criticism that they do not train students to be effective decision makers, many business schools have attempted to modify their graduate management programs. We suggest that a primary ingredient missing from these attempts is a comprehensive treatment of systemic thinking. While most business functions teach about the systems housed within them, we suggest that few teach their students to think systemically. We propose a 3-part description of systemic thinking and provide results of a survey that investigates the claim that students are not being taught to think systemically.
