Some people see non-profit organizations (NPO) as unattractive and unprestigious, because they donot make a profit and only take care of people who are waiting for a helping hand. This view is exacerbated by the existence of a stigma that NPO is not accountable and transparent in public accountability, not professional in performance. This study intends to conduct a discourse counter by discussing the implementation of strategic management in NPOs as a "requirement" for becoming a social entity that helps address various societal problems. The method used is a literature review by collecting data through relevant literature. The data is analyzed, compared, and common ground is drawn to obtain a complete understanding. Fifteen articles related to NPOs were found. Nine of them examine financial management including accountability and transparency, three discuss strategic management and quality management, one examines public relations and publicity, one discusses community engagement, and the other presents a critique of strategic management at NPOs. The results of the study show that first, the NPO concept is an organization that does not seek profit, but instead helps solve community problems on the basis of volunteerism, partnership and humanity.Second, strategic management is very relevant to ONP. Practically, there are two strategic management models, namely the Fred R. David comprehensive model with a three-stage cycle and the Wheelen and Hunger model with a four-stage cycle. Third, two crucial challenges must be answered by NPOs, namely: 1) commitment and consistency in carrying out performance accountability and transparency, and 2) firmness and sustainability in participation in realizing social welfare.
