ABSTRACT
In the time of crisis with Covid-19, the digital government has become a necessity for all countries. To continuously provide services to citizens staying at home, government adapts and creates ways to reach out to citizens digitally. Many new applications emerged, and these new applications accessible via mobile phone and through website and platforms must be standardized for citizens' convenient usage. There must exist a series of standards to ensure interoperability among the government digital service systems. This paper describes the standard and guideline development process invented and adopted at the Digital Government Development Agency (public organization) or DGA. It further summarizes the work that needs to be done for a complete solution and the groups such as standard committees involved in achieving this goal. The focus of the paper is on the standard development for interoperable digital government systems in Thailand. The development of the data catalog standard is presented as an example of applying the proposed approach. Standard and guideline development are a necessity for aligning digital government systems together. © 2022 IEEE.
