**6. Conclusions**

This chapter presents a study about the effect of the PBL on social skills development of first-year Industrial Engineering students. The instruments used provided evidence that PBL programs deliver a rich context where social skills can effectively be exercised and enhanced. A number of such skills were identified, and the development process thoroughly discussed, namely, effective team working, conflict management, effective oral and written communication, capacity of adaptation to different work environments, assuming responsibilities, caring about the other's learning, assessing the work of others and of their own, willingness to pertain and work in activities of student and professional associations. The acquired competences allow students to grow and become professionals capable of leading and working in projects and multidisciplinary teams.
