Culture provides the context within which people in organizations interact with one another and the world surrounding them. Many of us work routinely with people from other cultures and backgrounds. Often this goes well, and the cultural differences are interesting and enriching. However, sometimes things go wrong, for reasons that we may not understand. This is where it’s important to understand the differences between cultures, so that we can work with people more effectively, and prevent misunderstandings.
Trompenaars and Hampden-Turner’s Seven Dimensions of Culture, http://www2.thtconsulting.com/about/people/fons-trompenaars/ as well as Hofstede five Dimensions of Culture,http://geert-hofstede.com/ are two gurus within the Organizational Cultural field.
A very popular country comparison tool for different cultures can be found from the Hofstede´s homepage: http://geert-hofstede.com/countries.html
