It is often difficult to do business across cultures because much of business involves understanding one's business partners and their thoughts and expectations. When we do business with one another, much of what we think and expect remains unspoken. We know how business is done in our culture. When we speak to our partners, we will know what they mean when they say various things. When we do business across cultures, that easy understanding is not present. We and our partners may not share assumptions. We might not understand what the other means when we speak, even if we are speaking the same language. This can lead to all sorts of misunderstandings that can harm our relationships with our business partners.
