Electronic government (e-government) has become a paradigm-changing concept in public administration and the interaction of government with society. This transformation involves the implementation of information technology and the internet to improve efficiency, citizen-oriented services, transparency, participation, and trust in government. In parliament itself, the concept of e-parlement developed as an effort to increase transparency, efficiency, and public involvement in political processes and legislation. While this concept offers many benefits, some challenges need to be overcome. This research analyzes the implementation of e-parlement in developing countries, identifies challenges that need to be overcome, and provides lessons on the implementation of e-parlement in developed countries. The theoretical foundation covers aspects such as strategy, operations, technology, and digital transformation in the context of parliamentary digitalization. The source of data used in this study is secondary data from research related to the implementation of e-Parlement which has been researched and written in the form of articles that are then published in international journals indexed by Scopus. The method of searching for articles is carried out online, by searching through the Scopus and Google Scholar sites with the keyword "e-Parlement OR parlement digital" and the period is limited to the last 10 years. The results showed that some of the main challenges faced in the implementation of e-Parlement are information technology (ICT), the capacity of staff and parliamentarians to use ICT, and political will. Although e-Parlement is a cutting-edge concept, its implementation is not always effective in developing countries due to constraints such as inequality of access to technology. To that end, lessons from developed countries have provided examples of how strategies, digital operations, digital technologies, and digital transformation can guide to address these challenges.
