Purpose
This study aims to consider the capabilities of information technology as a basing dimension in the success of systems that provide electronic services as an e-government system. This study will focus on the role of IT capabilities in e-government system success by proposing a model based on the integration of the updated DeLone and McLean model is (D&M) with the unified theory of acceptance and use of technology is (UTAUT) model, which includes seven variables, namely, IT capabilities, information quality, system quality, performance expectancy, effort expectancy, perceived support quality and e-government system usage.
Design/methodology/approach
A conceptual framework was built across a review of the literature and the results of studies of IT capability and e-government systems success has developed the study model. As the causal approach was adopted to test the model of the proposed study. Survey data collected from 765 respondents who use the e-government system in Iraq. Also, a regression approach has been used to test the study model.
Findings
The results revealed that IT capabilities and the factors included in the “the updated (D&M) and (UTAUT) model” as important forecasts in the success of e-government systems. In another word, the proposed model provides managers with a new perspective to deal with the adoption of the e-government system by introducing a new variable “IT capabilities,” to provide decision-makers with a new approach in determining factors of e-government success.
Research limitations/implications
The government must develop their policies in line with e-government services to maximize the benefits accrued from e-government services. Where the main determinants in this study were the age group of the sample and the Arab environment for this study.
Originality/value
This study is the first in Iraq as a developing country and one of the few in e-government that considers IT capabilities as a basing dimension in e-government success by proposing a comprehensive model that sums the factors related to such a relationship. Its value stems from its sample of public users and the support of its proposed framework.
