The Trompenaars-Hampden-Turner model is a framework for understanding cultural differences in business and communication. Developed by Fons Trompenaars and Charles Hampden-Turner, it identifies seven dimensions of culture that influence how people interact and make decisions. These dimensions include Universalism vs. Particularism and Individualism vs. Communitarianism, among others. This model helps organizations navigate cross-cultural challenges by providing insights into varying cultural values and behaviors. By recognizing these differences, businesses can improve collaboration, enhance communication, and foster better relationships in diverse environments, ultimately leading to more effective international operations.
