Communicating across cultures effectively is important for business success. Cultural differences can lead to miscommunication if not properly understood. Culture refers to the shared ways groups understand the world and includes behaviors, beliefs, and practices. There are two major types of cultural differences that affect communication - differences in body language and differences in views of relationships regarding factors like time, space, intimacy, and emotions. Overcoming cultural barriers requires understanding these differences, communicating simply, continually checking for accurate understanding, and embracing diversity in the workplace.
