The document discusses several models for representing culture and their relevance for global information systems design and development. It describes Hofstede's dimensions of culture model and Henderson's 14 dimensions of culture in education. Requirements analysis for global information systems should account for cultural aspects by involving remote teams, using common modeling tools, addressing non-functional cultural requirements, and having a clear review process. Defining culture and comparing Hofstede's and Henderson's models is important for designing culturally aware knowledge management systems.
