Culture conflict in globalization

Globalization is a phenomenon that has made its presence felt in our daily lives and has changed the way we live and has led to the interaction between diverse cultures through convergence of world views, products and ideas, whereby cultural conflict can make or break a business that is trying to establish itself in a foreign country. One of the strategies that make a difference when it comes to establishing a successful presence in a foreign land is effective communication. This includes not just language and does not include only English as although English is the global language of doing business, many countries prefer to function in their local language which can be a cause for concern but this problem is minimized as most countries have a sizeable population who are bilingual and are comfortable with using English despite the fact that it is not their mother tongue. Non-verbal communication also plays an important role and one needs to be aware of the cultural nuances and cu...

Television - How It Works
