AbstractCross-sector collaboration is an innovative strategy and practice to be implemented by socially-driven organizations towards reaching sustainable development goals. However, it is challenging to develop successful, effective collaborations that are important to cross-sector dynamics and political contexts, particularly in developing countries, such as Indonesia. Therefore, the paper aims to examine how socially-driven organizations in Indonesia collaborate with other sectors by using certain factors. Besides, this research also investigates the success and failure factors of collaboration among sectors. To meet this goal, this paper examines three essential factors for cross-sector collaborations (power distribution, communication, and shared goals) from three different sectors (socially-driven organizations, governments, and societies).The research was conducted by semi-structured interviews using Zoom for video communication. In addition, the interview was analyzed by content analysis, while Bryson et al. (2015) are used to identify the sectors and factors of collaboration. The results showed that the three collaborative factors that are used in this research significantly affect the development of the organization to collaborate with the external three sectors. Furthermore, quality education becomes the most common goal of all collaboration. In addition, face to face communication, and the use of social media have a huge impact on the communication, promotion of the goals and defining the power to the other collaboration sectors. However, communication breakdown, unclear goals, powerless figures, and bureaucratic procedures become the main challenges of collaboration. Therefore, organizations need to develop alternative ways to tackle these issues.Keywords: cross-sector collaboration, socially-driven organization, Sustainable Development Goals, Semi-structured interview, document analysis, power distribution, shared goals, communication.
