Edward T. Hall was an American cross-cultural researcher who is known for describing high and low context cultural factors. He also defined two systems of time in the world: monochronic and polychronic time. Monochronic time is typified by German, Swiss, Scandinavian, and American/Canadian culture. These low-context Western cultures tend to concentrate on one thing at a time and stay on time. Polychronic time, present in high-context cultures like China, Japan, Mexico, Brazil, and Middle Eastern countries, is characterized by looser time schedules and taking time to develop deeper relationships prior to conducting business.

Suppose you are an American manager working for a company in Brazil. Would you 

(1) learn to adjust to polychronic time to avoid getting frustrated, or 

(2) attempt to change the culture of the company from within to get things done in a timely manner?
