Information and Communication Technology (ICT) affects how organizations deliver services to their customers. ICT is now used not only to improve back office routine activities but also to act as strategic partner for achieving organizational goals. Although ICT has many benefits for organizations, its assimilation is the most challenging process as there are high failure rates as reported by many researchers. This paper examines the factors that influence ICT assimilation in organizations. The extant literature in this area is focused on high-income countries. There is a dearth of ICT assimilation research in lowincome countries like Ethiopia. Therefore this study will attempt to validate ICT assimilation model developed for highincome countries with new data from a low-income country. A modified model of Chatterjee et al’s (2002) Web Assimilation model will be used to investigate ICT assimilation in Ethiopian institutions. Four variables (top management championship, extent of coordination, strategic investment rationale, and technology readiness) will be discussed in relation to ICT assimilation. This study will use survey method for data collection in service sector institutions run by the government.
