The COVID-19 pandemic has negative impacts on human well-being with significant consequences on social, economic, political, legal, and technological aspects of society. A key challenge in managing the pandemic particularly in developing countries is the lack of integrated health data, Previous research indicates that an Enterprise Architecture (EA)-driven national initiative has the potential to mitigate data integration issues. However, in-depth study of how EA initiatives provide a systematic solution to national health data integration in the context of COVID-19 data management is lacking. Using Indonesia as a study context, we conducted an in-depth case study to systematically explore factors affecting the current COVID-19 data integration issues and investigate how EA helps overcome the problems. In this research in progress paper we present our initial research findings and outline our future research plans. When completed, our study contributes to IS research specifically in the EA domain and has important practical implications.
