E-Government have emerged quickly in the developing world. This is because of its effectiveness and enabling to increase efficiency and performance for the public sectors. However, the use of the technology varies from sector to sector because of the less concern of e-governance towards their work performance. Nowadays, very few public sectors are good at their day to day activity, which is IT supported. Other organizations had low IT use and budget allocation. Therefore, we proposed a data-driven e-government frame work to improve the quality of public sectors decision-making process. Another goal is to evaluate the current stages of e-government application in the public sectors. Data-driven E-Government needs to deliver effective government services to the customer by using information technology (IT) and making a verifiable decision. This thesis work covered the challenges and prospect towards performance optimization. As many researched works showed many e-government framework implementations on quality service delivery and promoting good governance is in infant stage. It provides better foundation and understanding about how to use of the sector data. We used primary data that collected from five different locations and 27 public federal, regional and zonal sectors. The data were collected using questionnaires, interview and personal contact to the respective domain experts. qualitative research approach is followed as this method is found appropriate in order to understand, describe and explain e-government and its relation to efficient government service delivery in the public sectors. And also, the quantitative research approach is followed because, it is useful to investigate the research question in depth. Via the descriptive quantitative research approach, the research problem is diagnosed. The research method found appropriate for this study is a survey (it is a method of collecting data in consistent way). viii This research empirically examined the adoption of e-government at organizational level, by taking the public sectors of Ethiopia. Appropriate stastical tools such as frequency tables, percentages and percentages are used in the analysis, interpretation, presentation and drawing of conclusions. The findings of the research contributed to the identification of current status of Ethiopia in e-government service delivery, and to the development of a data-driven e-government adoption framework. The framework combines elements from the basic determinants of egovernment platforms (HW and SW infrastructure, Platforms, Interoperability and Public Sectors Partnership) and also from data-driven decision-making skills which are: Data, Information, Knowledge and Decision. The use of the proposed framework can help integrate e-government in to the public-sector in order to accelerate social and economic progress in Ethiopia. The contribution of the findings is to increase IT application concern, motives and commitments. Moreover, the advantage of the proposed framework is to combine electronic governance in public sector organizations to increase economic growth to the country.
