Purpose – This study aims to investigate factors that influence e-government adoption among public sector departments with the view to determine how such factors may be used to better facilitate e-government adoption across United Arab Emirates (UAE) public sectors. The use of e-government is advocated for the central government in the UAE. Design/methodology/approach – Using random sampling, a total of 172 participants from ten departments and organisations in Dubai and Sharjah completed the online survey for this pilot study. Findings – The authors found that performance expectancy and facilitating conditions have positive effects on e-government adoption. Furthermore, this study revealed the factors that encourage more e-government adoption between government organisations in the UAE. This study reveals three facilitating conditions may encourage e-government adoption in UAE public sector organisations when short- and long-term performances have positive effects on e-government usage. Practical implications – This study provides middle managers clarity on factors that would influence government-to-government (G2G) uptake in more government organisations across the country. For uniformity and consistency, middle managers are now better informed as a result of this study to determine how best to use the six factors to motivate subordinates for more effective G2G. Originality/value – The scope and results of this study is a contribution to e-government studies because it identifies the factors that positively influence G2G adoption. This scope exceeds the studies by Chan et al. (2021) and Habib et al. (2020) which focuses on the use of e-government for citizens or the public. This study focuses on the use of e-government within the government and between government departments.
