Abstract
During the beginning of the 90's, the European industries of aeronautics and space already cooperate in many partnerships and common programs. Soon the need for gathering seems to be essential to the concentration movements on the US market. Indeed, Northrop and Grumman merged in 1993, as well as Raytheon and BAe Business Jets in 1994 and Lockheed and Martin Marietta in 1996. The objective of the "grouping" is to impose itself on the international market to a concentrated competition. It is in this context that EADS was born, which is a merger of not two but three companies: AEROSPATIALE MATRA SA, a French company, CASA, a Spanish company, and DAIMLER CHRYSLER AEROSPACE, a German company. In spite of the apparent geographical proximity, new important challenges appear including economical, financial, social, structural and cultural aspects. In fact, risks of failure are very important and increase by the cultural differences existing during the connection of the cross border companies. That why it seems to be essential to include measures which will take in consideration the diversity in the supervisory company.
