This study investigates the level of organizational prowess among workers in social solidarity departments, the extent of institutional performance development, and the relationship between these two constructs. Employing a descriptive research design and comprehensive social survey method, data were collected from 67 employees in the Social Solidarity Directorate of Giza Governorate. Findings indicate high levels of both organizational prowess and institutional performance development among workers. Moreover, a statistically significant positive correlation exists between flexible organizational structure, investment in available resources, exploration of external support resources, and dimensions of institutional performance, including efficiency, justice, rewards and incentives, and participation in decision-making. These results validate both the main hypothesis and its sub-hypotheses.
