In Windows on the World, participants explore how national culture differences may affect managerial practices when expanding into another country. In the exercise, a U.S. niche grocery retail chain plans expansion into Brazil and China. The role-play is between a consultant team and a client team that has hired them. The consultant team gives expert advice about which, if any, of the managerial practices in place in the home market might require modification in Brazil or China. Facilitators can suggest “cultural due diligence” as a way to increase the likelihood of successful international business expansion.
