Many researches have been done during the last century to identify the skills of an effective manager and the characteristics of a good multicultural manager. As the importance of managerial competences has increased, global managers are expected to go through a constant process of learning and development. Nowadays the researchers find out that many different approaches to managerial competences are necessary to be a successful multicultural manager. Competences were the ability to put into non-routine cognitive intelligent actions. We take out 3 important points as competences in managing a multicultural workforce. First, and probably the most important one, is the possession of interaction skills across cultures, followed by learning and communication elements.

Usually the manager in a multinational organization needs to analyze cultural differences between his/her natural culture and the foreign culture. An approach that may be useful is to identify the various dimensions of culture and the cultural differences that could be measured. There are several different types of skills and characteristic essential to successful manage a multicultural workforce. A manager must be able to look at things from diverse perspectives. Different analysis have been conducted in order to find out which main skills are important for a manager of a multicultural workforce group, and provide a framework for competences in managing such workforce. In addition, the researches point out how the various skills and characteristics are linked together.

Managers need to have tolerance for ambiguity to understand the different aspects from their own culture to another. The higher tolerance level of ambiguity, the higher is the understanding of attitudes and behaviours of other cultures. Therefore we state a hypothesis that: "Tolerance for ambiguity will be a component of competence for managing multicultural workforce"
