Abstract

During the last decade government organisations in Kenya have worked to automate processes and digitize information and services using various systems. These systems have however become diverse due to the various vendors and their use of different data formats, storage types, languages and technologies, thus the issue of heterogeneity and interoperability of systems. This has created a need for an integrated platforms to enhance sharing of information and services between organisations. The E-government platforms in Kenya are growing to a size that requires a framework that ensures an integrated platform for the e-government applications and services provided to citizens, business and other government agencies. Currently most e-government platforms are independent thus result to redundancy of efforts, inconsistency of data and lack of integration, while some platforms are peer-to-peer integrated resulting to tight coupled system, and tedious process of adding of new services into E-government systems. The aim of this research is to use the eCitizen portal in Kenya as a case study, thus understand the challenges that users and technology support staff have with the current e-government systems by use of questionnaires, and use Service Oriented Modelling and Architecture (SOMA) to come up with a Service Oriented Architecture (SOA) Model that can be used meet most of these challenges, and also validate this model using a prototype. The SOA model has shown how we can use SOA to reduced costs, less redundancy of data and effort, shared information and services, interoperability and ultimately better service delivery using a SOA integrated eCitizen platform.
