This chapter discusses culture and its impact on management approaches. It defines culture as acquired knowledge used to interpret experiences and generate social behavior, forming values, attitudes, and influencing behavior. The chapter describes Hofstede's and Trompenaar's models of cultural dimensions that influence work behavior internationally, such as individualism vs collectivism and universalism vs particularism. It also summarizes the GLOBE project which extensively studied cultural attributes across over 60 countries to provide insights into managing cross-culturally.
