Abstract: This research tests the information system usage (ISU) among the four listed telecommunication companies in Sudan. The proposed model analyses the effect of antecedents on ISU and the effects of the subsequent ISU on consequences. Through a purposive sampling technique, a total of 335 completed questionnaires from end-users were collected and analysed. The findings indicate that antecedents and consequences ISU model display a good fit. The study revealed that top management support, training, business IT alignment, information centre services were significant antecedents that affect ISU while information system investment was not significant. ISU has a significant effect on product differentiation, product innovation, process innovation, organisational performance, and strategy formulation but has no effect on competitive advantage. The study findings provide information system practitioners and managers with guidelines that can encourage ISU more efficiently and effectively. The study also discusses these findings and concludes with the limitations and future recommendations.
