This project consists in the creation of an on-line course in English to help European companies communicating between principals and subcontractors.The big companies in the fields of automobile, telephone or aeronautics for instance work with subcontractors all over Europe. All the communication involved between technicians of both sides has to be in English, although often, neither side is English-speaking.The course will consist in technical dialogues recorded in and transferred into English. These correspond to real situations concerning the different phases of the industrialisation of a product: technical specifications, technical discussions, quality insurance, environmental norms, presentation of a prototype, trials, modifications, all stages bringing to effective production.
