E-government facilitates the use of Information Technology to establish government public services. A common feature of e-government is a Website as public portal. One of prominent institutions in Indonesia, which is obliged to provide the Website is the Central Bureau of Statistics. However, a data requirement survey by the Central Bureau of Statistics in 2017 indicated a gap between user expectation and user satisfaction of the Website. Besides, an assessment by the Open Data Inventory (ODIN) indicated that the Website has not met the international Website quality criteria, especially data completeness and data openness measures. To address this problem, a research was conducted to investigate its shortcomings and propose strategies for improvement. The data were collected using questionnaires, which were grouped into the Importance Performance Analysis (IPA) matric quadrants. It was followed by literature studies and interviews with experts in statistical Website to propose improvement strategies. The priority of strategies was compiled using the Quality Functional Deployment (QFD). The results show that the Central Bureau of Statistics are required to optimize the Website code, redesign the Website layout, create statistical data forum, conduct statistical capacity building, and improve the data interoperability. Lesson learned from this research and its findings are potential to be adopted in other emerging economies, which strive to provide qualified data on e-government Websites to their citizens.
