It was back in 1992 when David Victor published his LESCANT model of International Business Communication. I still use it today because it seems to be the best way to categorize cultural differences. The acronym LESCANT stands for Langage, Environment, Social Organization, Context, Authority, Non-Verbal, and Time. What follows is a brief powerpoint slide presentation where I have summarized some of the major points of the LESCANT model.
