We believe that a set of tools and curricular activities involving students from different countries, collaborating to complete projects that generate relevant outputs to the community, might improve both students' enthusiasm and their team work and communication skills. That is the mission of the Multinational Undergraduate Team Work project (MUTW). The MUTW methodology is devoted to create and manage future international teams of students who will collaborate in order to develop a solution for a given engineering problem. The methodology encompasses all the timeframe of an edition of MUTW, including preparation of the students' project and its deployment by the teams of students.
