    Factors Affecting Strategy Implementation In the Case of Ethiopian Airlines
    (A.A.U, 2021-05) Tesfaye, Mihret; Werkaferahu, Yohannes (PhD)
    Studies have shown that strategy implementation is still a challenge for today’s organizations due to several factors influencing the success of strategy implementation. The purpose of this study is to assess the factors affecting strategy implementation at Ethiopian Airlines by analyzing the relationship between elements of the Eight “S” model that affect strategic implementation and the strategic performance achieved by the airline. The research question, to which the researcher sought an answer, was to assess whether there was a relationship between the seven elements in the Eight ‘S’ mode and the strategic performance of the airline. The study used a survey to gather the quantitative primary data from 265 managers and team leaders of Ethiopian Airlines. The data was then studied using descriptive, correlational and regression analysis on SPSS (version 20). The findings of the study generally agree with earlier studies on strategy implementation. The seven factors considered in the study (the strategy, organizational structure, systems and processes, leadership, human resource/staff, resources, and organization culture) are all found to have a positive correlation with the strategic performance of the airline. Testing of the research hypotheses further has shown that the factors defined as organization culture, leadership, and strategy are found to have a high impact on the strategic performance of the airline. Factors defined as resource and human resource have a relatively lower impact while the impact of systems and processes and organizational structure is found to be insignificant. Based on the findings, to achieve success in strategy implementation, the study recommended giving more emphasis to those factors with a high impact on the success of strategy implementation.

    Open Source ESB Based Application Integration Case of Ethiopian Revenue and Customs Authority
    (Addis Ababa University, 2016-12-06) Tesfaye, Mihret; Getahun, Fekade (PhD)
    Nowadays integration and interoperability becomes a key issue for organizations that work together. Enterprise Service Bus has become the ideal integration architecture for heterogeneous systems that facilitates integration between disparate applications with different hardware and software platforms. The aim of this work is to assess services provided by Ethiopian Revenue and Customs Authority for vehicle declaration those require integration and study the workflows of the existing system. This study provided an Enterprise Service Bus product evaluation matrix and four open source ESB products evaluated and the appropriate product for implementation selected. After discussing core ESB concepts, features and benefits, proprietary and open source ESB products are described briefly. The Enterprise Service Bus product evaluation matrix prepared by reviewing variety of research papers by different professionals and organizations and the products evaluated based on the matrix. Based on the result from the comparison, the WSO2 ESB is used for developing the integration scenario. The development of the scenario is done using WSO2 ESB and detail information on the design and development is included. Finally the design and implementation of the integration scenario is done using the selected ESB solution that is WSO2 ESB and the integrated system evaluated by performing functional testing. The result of the functional testing indicated a successful outcome for all the test sets.
