Max Bazerman has had extensive experience teaching corporation's executive negotiation courses. In addition to the faculty and students, some of his sessions have been attended by high level former diplomats who had worked on cases discussed in class. The diplomats were invited, where appropriate, to provide insight into local customs, changing politics, and business norms. They provided that knowledge - and much more. The diplomats taught the groups, faculty and executives alike, to think more broadly about information that is not obviously relevant to a given negotiation but is crucial nonetheless.
