Previous stunting-related studies focus more on causes or determinants of stunting. Little is known about factors contributing to the success of stunting reduction programs. This study aims to fill those gaps using a case study from Ende District, Province of Nusa Tenggara Timur, Indonesia. A group model-building workshop with stunting-related stakeholders was conducted in November 2021. The system dynamic approach in the form of a causal loop diagram was used. Five variables related to the stunting reduction program were included in the analysis: the budget for the stunting reduction program; stunting-related stakeholder's cooperation and coordination; sufficient water supply; the ability of the related stakeholders to execute the program; and water, sanitation, and hygiene-related behavior. We found that the budget for the program and the cooperation and coordination between stakeholders were the most influential variables in the system. The feedback loop between these 2 variables was also the most prominent in the system, suggesting that sufficient funding and strong collaboration between stakeholders could lead to successful stunting reduction programs. Finally, this study implies that the stunting reduction programs in developing countries should be seen holistically and improvement should be conducted in all aspects, including financial, institutional, environmental, technical, and social.
