Information Communication and Technology (ICT) utilization has become a backbone of e-government implementation.Six components of information system (hardware, software, people, data, process and network) are combined to deliver information from government to their citizen as part of public services.However, there is an interoperability challenge on e-government implementation related to information system.These systems due to different vendors and their use of different storage types, data formats, languages and middleware platform have become diverse, hence the challenge of interoperability due to heterogeneity of e-government information systems.This has led to the need for organizations to share information and services through interoperability platforms.Currently most e-government platforms are independent thus result in lack of integration, inconsistency of meaningful data and redundancy of effort.The main aim of this study was to develop an interoperability framework for egovernment information system which will improve efficiency and effectiveness of government services through accurate sharing of information among various information systems while the specific objectives were to identify the factors that affected egovernment information system interoperability, determine the critical factors that influenced e-government information system interoperability.
