Key contributing factors towards successful Electronic Government systems interoperability

Electronic Government (e-Government) is an initiative of transforming public sector delivery system towards high performance services and citizen oriented. The emergence of broadband and communication technology has catalyzed the growth of online systems forming the main thrust of e-Government. However, the satisfaction level of e-Government systems remains low because of recurrent transactions in different users systems. In addition, most of e-Government systems are still not integrated. Successful integration can be achieved if interoperability factors are completely defined in a framework and introduced in the early stages of system development. This paper aims to review existing e-Government interoperability frameworks which are European Interoperability Framework, e-Government Interoperability Framework (UK), Standards and Architectures for e-Government Applications (Germany) and E-Government Interoperability Framework (Greek). These frameworks were analyzed using content analysis method to identify the key successful factors towards e-Government systems interoperability. The factors were grouped into two dimensions; people and process. These dimensions and factors subsequently become the basis for developing a holistic and integrated framework in the future.
