Open Government Data (OGD) is a concept that combines open government with transparent, collaborative, and participatory data provision. Indonesia has adopted this concept through the Satu Data Indonesia (SDI) program. However, the practice of SDI management has not shown significant development compared to other developing countries in the Asia Pacific. This can be seen from previous studies that were limited to the application of OGD to the internal aspects of the organization, and have not examined the overall constraints between agencies as data producers. In addition, strategic aspects such as policies, regulations, and organizational arrangements have not been fully assessed according to international standards. This study aims to formulate success criteria in OGD assessment and design evaluation instruments based on national regulations. The method used is the Design Science Research Methodology (DSRM) with an exploratory-sequential approach. The study results showed 61 valid indicators spread across seven policy dimensions, collaboration, quality, information technology, portals, and impact, with an ICC score shows moderated agreement. The trial was conducted at the walidata and the data producer. It was found that the technology and portal dimensions were not relevant for data producers because they were managed directly by the walidata. The instrument offers clear acceptance criteria and supports ongoing internal evaluation and improvement in OGD implementation.
