MEASURING THE SUCCESS OF E-GOVERNMENT SYSTEMS: APPLYING THE SUCCESS MODEL OF THE DELONE AND MCLEAN INFORMATION SYSTEM

摘要

The success model of an information system from an Iraqi citizen?s perspective was utilized to examine the e-government system in developing countries, exclusively in Iraq's environment. Partial Least Square path modeling algorithm was applied as a fundamental technique to analyze the collected data using a questionnaire of 160 citizens in Iraq. The proposed model was developed by modifying the updated DeLone and McLean IS success model. The proposed model consisting of the previous six constructs from the updated D&M model was integrated with trust constructs. Results empirically corroborate that ten hypotheses among the seven constructs are supported significantly, whereas the other three are less supported. Model constructs are affirmed to affect the citizen intention and satisfaction positively. The impact gradually decreases from trust as the highest influence constructs, followed by service, system, and information qualities. Trust is confirmed as the main powerful construct that positively influences the Iraqi citizen?s usage intentions. The managerial implications of these research results contend that the Iraqi government agencies, along with the system developers, must pay extra attention to the proposed model constructs that influence the citizen?s intention to use an e-government system, specifically the construct of citizen trust.
