Modern international trading practices are highlighting the growing importance of language training.
Modern-day business really does transcend national barriers. Thanks to sophisticated IT and communications systems, businesses can now market their products on a truly global scale. The world is indisputably becoming a smaller place, as service and manufacturing companies search the international marketplace for new suppliers and clients. Businesses must, however, be aware that once they expand the area in which they operate, they face increased competition. The standard and quality of their goods become increasingly important in keeping up with competitors. But most of all, it is the service element accompanying the goods which is crucial to a company's success in a particular market. This new philosophy has led to many companies, some of which have even offered products of a lesser quality, gaining success overseas.
Although globalisation may, in some senses, have brought national economies closer together, societies around the world still have radically different expectations, processes and standards. These are not a function of economic change, but are more deep-rooted and difficult to alter. They can be a major problem for businesses expanding abroad, with the greatest obstacle of all being the language barrier. If you have to deal with clients, suppliers and distributors in a range of countries, you will not only need the skills to communicate with them, you will also need to reconcile any national biases you have with the diverse ways of doing business that exist around the globe.
The value of effective communication is not to be underestimated. New technology such as videoconferencing and email has played a part in making the communication process easier, and it may also be possible that the introduction of language interpretation software will help with some global communications problems. But, of course, it is the human element of the communication process that is so vital in business, especially in negotiations, presentations and team-building. It is essential for managers to meet regularly with staff, customers and partners, so that issues can be discussed, messages communicated and feedback obtained.
The value of well-organised language training is immense, and can bring benefits to all levels and departments within a multinational organisation. Unfortunately, however, many organisations have a very narrow view when it comes to training of any kind. Often, an urgent requirement has to be identified before training is authorised. Then, a training company is employed or a programme is developed in-house, the team is trained, and that is seen as the end of the matter. However, the fact remains that training programmes are effective only if they are relevant to a company's broader, long-term needs. They should be regarded as an investment rather than a cost.
Changes in expectations and attitudes are certain to continue for companies that trade globally. Although such companies are not yet faced with their international partners and clients demanding that business be conducted in their mother tongue, they realise that overseas competition is increasing fast. If these companies want to continue to achieve success on the international trading circuit, they must be prepared to adapt to situations and speak the local language. If not, someone else will.
