The study was aimed at establishing the impact of management information technology on quality service delivery in government institutions using Greece as a case study. Specifically, the study sought to examine the relationship between IT infrastructure management, IT support systems, and Informational products and quality service delivery respectively. A cross-sectional survey research design based on a sample size composed of different government officials in Greece government institutions was conducted. Data was collected using survey questionnaires and document review. Data was first presented, analyzed and results interpreted based on descriptive statistics for categorical data and narratives for open ended questions. The study confirmed a significant positive relationship between the different independent variables (IT infrastructure management, IT support systems, and Informational products) and the dependent variable (Quality Service delivery) (p<0.001). The ANOVA results indicated that respondents had varying opinions about informational products and relatively similar information about quality service delivery in government institutions. The regression results showed that the three study variables could only predict a 34.1% change in quality service delivery in the different government institutions in Greece. Among the different predictors of service quality, control (Beta = .351, p < .01) was a better predictor. The Study confirmed that there is the relationship between the different aspects of management information technology and quality service delivery in government institutions. The study recommended that government institutions should adopt new advanced tools of developing and managing information systems or technologies so as to enhance service delivery in these institutions. The study also advised more research be conducted to explore the different strategies that can be applied towards improving the robustness of management information technologies in public institutions.
