This study aims to identify the critical factors for enhancing the government performance management system in Indonesia. The research was carried out in three major provinces: Yogyakarta, South Sumatra, and West Java Province. Employing a mixed-method approach, the study utilized descriptive research with both quantitative and qualitative analyses. The quantitative analysis involved multivariate regression analysis conducted using R-Studio, while the qualitative aspect included insights from selected key informants. The findings of the study highlight that leadership commitment and internal policy support are the most influential factors in sustaining the government performance management system in Indonesia. Additionally, such factors as organizational structure stability, working culture, conformity to national policies, clarity of performance cascading, and quality of human resources showed positive correlations. However, the use of Information and Communications Technology (ICT) was found to have no comprehensive correlation in supporting performance management systems.
