The deregulation and privatisation of the energy market has changed the reality drastically for the power supplier companies. This thesis concerns the global enterprise Alstom Transmission and Distribution (T&D) and their countermove to face the constantly evolving market and their customers’ needs. The countermove consisted of an International Sales and Country Organization, ISCO, which is the main topic of this thesis. Alstom wants to create a one face to the customer mentality and ISCO will thereby handle all of the customer connections. The purpose of this investigation is to find the critical issue of a successful ISCO and illuminate how these issues can be beneficial to Alstom if considered. To gather the relevant data we travelled to Switzerland and the headquarters in Paris to interview employees with relevant knowledge of ISCO. Then we let the results collide with our theoretical framework and afterwards we analysed the outcome of it. Alstom T&D faces intensified competition and needs to create a competitive edge with the new organizational structure. We have identified six critical issues crucial to the success of ISCO; business relationships, motivation & participation, the customers’ expectations, customer focus, organizational change and company culture. The reorganization means that the employees need to adjust mentally to the new way of thinking, which is to be customer focused. The employees must also feel as if they are a part of the change and that they are motivated to work within the new organization structure. In order to meet the customers’ needs, T&D must be aware of and mange the customers’ expectations. We found that there was a lack of a tangible company culture within Alstom T&D and, it is imperative that they manage to build up a strong and inspirational culture of their own. Handling business relations will be one of the major tasks for ISCO personnel, both with the customers and the co-workers. Finally, customer focus must become a reality for the whole organization, not only within ISCO.
