In recent years, the world has witnessed growing concern about social issues and assistance. People join to create organizations with the only goal of trying to mitigate social problems. This gives rise to the so-called Tertiary Sector, which is expanding and manages to help to fulfill the needs generated by the government’s incapacity to play its role. Nevertheless, many organizations in this sector present management problems. The methodology focuses on a bibliographic review of the subject, as well as an empirical research. The empirical research has shown that it is actually possible to apply value based management, provided that modifi cations are made for the organization’s economic assessment. This study presents an adaptation of value based management, a tool used by for-profit companies, to tertiary-sector organizations, as well as the calculation of EVA™ for not-for-profit organizations.
