The pre-requisite to take a behavioral science course, either Managing in Organizations or Managerial Decision Making, prior to taking Strategies and Processes of Negotiation is soft (i.e., not required), but very highly recommended. The behavioral science faculty's experience is that exposure to some understanding of psychology as taught in our behavioral science classes (e.g., social influence, biases in cognitive or social judgment, etc.) before you take the negotiation class not only solidifies your understanding of the psychology you learned in the previous behavioral science class, but also greatly improves your understanding of how to negotiate.
