David Livermore, author of The Cultural Intelligence Difference, defines Cultural Intelligence Quotient (CQ) as one's ability to function effectively across national, ethnic, and organizational cultures. From a misinterpreted gesture, to an email in lieu of a phone call, there are implicit actions, rules, and guidelines that differ from countries or even corporations, that can make a profound professional impression. Knowledge of these nuances isn't innate, regardless of skill-level, IQ, or EQ. But CQ can be learned. David outlines the four areas of CQ and why your proficiency in them can be the defining factor in your career progress.
