This presentation discusses cultural modeling frameworks developed by Geert Hofstede and Richard Lewis. Hofstede developed the cultural dimensions theory, which quantifies cultural differences across countries on dimensions like power distance, individualism vs collectivism, masculinity vs femininity, uncertainty avoidance, and long vs short term orientation. Lewis proposed a model for cross-cultural communication that involves distinguishing cultural perspectives, building self-awareness, avoiding stereotypes, and respecting cultural differences. Understanding these cultural frameworks is important for conducting successful international business.
