XEXO constituted a network of tele-education that served the needs of three Greek universities (Athens University of Economics and Business, University of Macedonia, and Technical University of Crete). A tele-education system was installed in each one of the involved academic institutions, via which were taught 3 thematic objects (Electronic Commerce and Business Processes, Occupational Health and Safety, Business Process Modelling). The role of AUEB in the project was focused in a) Instructional design, and b) Design and Development e-learning courses.
