Hofstede's Cultural Dimensions model identifies five dimensions that can be used to distinguish cultures - Power Distance, Individualism, Masculinity, Uncertainty Avoidance, and Long Term Orientation. Psychologist Geert Hofstede developed this model based on extensive research with employees of IBM in over 40 countries. Each country is given a score between 0-100 for each dimension, indicating where they fall relative to other cultures. Understanding a culture's scores can provide guidance on effective communication and workplace practices when interacting with people from that culture.
