This study aims to analyze the implementation of agile governance principles in the management of the smart city program in the City of Yogyakarta. Using a descriptive qualitative approach and a case study design, this study relies on secondary data from official local government documents, smart city program reports, and digital service platforms such as Jogja Smart Service (JSS), Gatra Matra, and Qrisna. Data analysis was conducted iteratively, categorizing findings based on the six principles of agile governance: good enough governance, business-driven, human-focused, based on quick wins, systematic and adaptive approach, and simple design and continuous refinement. The analysis results indicate that the implementation of agile governance in the City of Yogyakarta has proceeded selectively, with primary strengths in the principles of “based on quick wins” and “good enough governance,” as evidenced by the success of digital services in providing fast and realistic access aligned with the region’s capacity. However, the principles of a human-focused, systematic, and adaptive approach, as well as a business-driven approach, remain at a moderate level due to reactive community participation, reactive adaptation, and a private-sector collaboration that is not yet optimal. This study concludes that the success of a smart city is determined not only by technology adoption but also by the deeper integration of agile governance principles. These findings have important implications for local governments in strengthening mechanisms for public participation, system interoperability, and cross-sectoral collaboration to achieve more adaptive, inclusive, and sustainable urban governance.
