IT integration implementation in e-government public sector in developing countries: a systematic literature review and model development

PurposeThis paper examines factors influencing successful information technology (IT) integration in developing countries' e-government sectors, analyzing benefits and challenges to understand interconnections among factors. This study aims to overcome barriers and maximize benefits, contributing to advancing knowledge and effective IT integration implementation practices, to enhance service delivery. Design/methodology/approachThis paper uses interpretive philosophy and qualitative methods to explore factors affecting IT integration implementation. Using systematic literature review, it identifies key knowledge, insights and future research directions, contributing to theory enrichment through model development elucidating IT integration factors influencing IT integration implementation in the e-government public sector and its broader ecosystem. FindingsThe findings indicate that while IT integration implementation enhanced efficiency, data security and service delivery, implementation challenges such as resource constraints, resistance to change and interoperability issues, exacerbated by the COVID-19 pandemic's impact on remote and hybrid work, are evident. Unique to Nigeria are public trust and unreliable power supply issues, significantly impacting service delivery. Notably, the study emphasizes the interconnection between these challenges and benefits, illustrating the complexity of IT integration in the e-government public sector, aligning with similar findings in the literature on other countries. Research limitations/implicationsLimitations include regional variations and a narrow temporal scope, impacting generalizability. Methodological choices may affect inclusivity, and contextual factors might not be fully captured. Policymakers can use findings for targeted strategies, while collaboration fosters understanding and monitoring ensures sustained success. Originality/valueThe study's originality lies in its comprehensive examination of IT integration in the e-government sector, especially in developing countries like Nigeria. Through a systematic review from 2004 to 2024, it identifies unique challenges and benefits, emphasizing management's role and proposing innovative frameworks for future research.
