Accountability is a prerequisite for the success of non-profit organizations (NPOs). Accountability promotes good governance, proper management, and trust among stakeholders. Joint accountability, where everyone participates in decision-making and is held accountable, is the best approach. While achievements are important indicators of success, NPOs must also be accountable to stakeholders and focused on their mission. Accountability is important for financial management as well as human resources and overall management. Transparency, codes of ethics, standard operating procedures, and partnerships that emphasize accountability can help NPOs avoid bad practices and increase sustainability and success.
