This paper proposes a tool to support decision-makers of social institutions in the process of selection and evaluation of their projects. The proposed model was created out of necessity mapped in the organization s strategic planning process, to obtain indicators for evaluating objectives aligned with its mission and vision and with aims of starting a institutional strategic management process. The proposed model, inspired by the Balanced Scorecard, respects the characteristics of a social institution, is not-profit and presents other special features when compared to private companies. Qualitative and quantitative methods were used to map the key indicators for evaluating the organization s projects, thereby obtaining a model adhering to the needs of the institution studied. As a result, the Matrix Assessment Project was created, which seeks to align developed projects to the business strategy, enabling the prioritization of projects and discarding those not aligned with the organization s strategic goals. The model provides standardization of project analysis, enabling the assessment of projects carried out or proposed on the basis of their performance in relation to the established indicators, the reallocation of investments and redevelopment of projects in accordance with corporate strategies. Preliminary results suggest that the proposed matrix is configured as a useful tool for selection and evaluation of socio-cultural projects, as well as an appropriate feedback tool, organizational learning and strategic alignment.
