Acceptance and Use of E-Library Services in Ethiopian Universities: The Case of Addis Ababa and Adama Universities
(Addis Ababa University, 2010-07) Ali, Abinew; Beshah, Tibebe (PhD)
The introduction of new information and communication technologies in libraries during the last two decades has altogether changed the concepts of libraries where library patrons need not necessarily go to the library physically since the library services and resources are no longer confined to the walls of the physical library. However, for these e-library services to be utilized effectively and efficiently, library end users must accept and use them. This study was mainly conducted to empirically investigate the determinants of elibrary end users acceptance and use in academic libraries within Ethiopian context. The study had applied the SO-UTAUT technology acceptance model which is appropriate in a library context. Cross sectional survey research method was used to capture the data. Questionnaire survey was employed to collect data from both Adama University and Addis Ababa University postgraduate students and academic staffs. SPSS and PLS graph beta testing software were used to analyze the data. Hence, Descriptive statistics and Structural Equation Modeling techniques using PLS were applied for analysis. The study found out performance expectancy as a major determinant factor which demonstrated the most significant contribution (36.2%) on behavioral intention to use elibrary services. Moreover, behavioral intention has shown to be the core determinant factor (40.2% contribution) for the actual usage behavior. Awareness has demonstrated a significant moderating effect on relevancy and facilitating condition constructs. The SO-UTAUT model has been proved to be valid in Ethiopian context, since it can explain 22.2% of the variance on behavioral intention, 29.9% of the variance on behavioral usage and 52.2% of the variance on expected benefits of e-library services in the users’ acceptance and use behaviors of the services.
Application of Data Mining Techniques to Predict Customers’churn At Commercial Bank of Ethiopia
(Addis Ababa University, 2013-09) Gebremeskel, Kassahun; Teferi, Dereje (PhD); Beshah, Tibebe (PhD)
Data mining tools and techniques are being used to solve different types of problems in various industries. Predicting customers‘ churn is one of the areas where data mining can be applied. Customers‘ churn, which is the common measure of lost customers, is one of the major problems in industries such as banks where there is a fierce competition. By minimizing the number of churning customers companies can maximize their profit and sustainability. For this reason, customer retention is critical for a good marketing and a customer relationship management strategy. This paper presents the prediction of customers, who are prone to move to a competitor, in Commercial Bank of Ethiopia. The data of 13172 customers with 9 attributes and their corresponding 628,634 transactions with 10 attributes is collected from the bank. The CRISP-DM methodology is followed to conduct the data mining process. After the business is thoroughly analyzed and the goals are clearly identified, successive steps of a data preparation processes are undertaken. A dataset of 6045 instances and 18 attributes is prepared. A WEKA (Waikato Environment for Knowledge Analysis) tool is used for modeling. The dataset is partitioned into different sets of testing and training sets. As the proportion of the churn class is very small as compared to the active (non-churn) class, SMOTE (Synthetic Minority Oversampling Technique) has been applied to minimize the class imbalance problem. Three modeling techniques are used for predicting churn. These are J48, Logistic Regression, and Bagging. The training models are built using cross validation and tested for reliability by separate test sets. The models are evaluated by their F-Measure values (which is the harmonic mean of recall and precision). The results of the study show that J48 modeling technique is the best model with a performance of 94.8% followed by bagging (93.9%) and Logistic Regression (76.6%).
Constructing Subscription Fraud Detection Model Using Machine Learning Algorithms: the Case of Ethio Telecom
(Addis Ababa University, 2021-01-05) G/Tsadik, Hailemeskel; Beshah, Tibebe (PhD)
Nowadays, the advancement of telecom services are becoming an essential communication means for people’s day-to-day activities. However, this development provides some appearances that motivate fraudsters. Telecom fraud is a serious challenge in telecommunication industries. It is a threat for telecom companies to lose some percent of their annual revenue and to provide poor quality of services for their customers. Subscription fraud is one type of fraud in today’s telecom business. It is a common and major types of telecom frauds in which the usage category is in contradiction with the initial subscription type. The main objective of the fraudsters is to make money illegally or getting telecom services with the intention of not to pay for the service they used. The purpose of this study is to construct a model which uses machine learning Algorithms to detect subscription fraud calls by using Call Detail Records (CDR) data. The general approach used to perform this research was a quantitative laboratory experimental research method. Three classification techniques of machine learning algorithms have been applied; which are, Random Forest (RF), Support Vector Machine (SVM) and Artificial Neural Network (ANN) multilayer perceptron algorithms. WEKA data mining tool has been used to build a model for predicting fraudulent calls. The experimentation results of the work show that RF classifier performs better among the three algorithms with an accuracy of 99.46%. The major finding of this research is that, ten interesting factors used to identify fraudulent subscribers from legitimate ones. Some of the attributes such as, Subscribers total number of calls, number of unique called numbers, number of incoming calls, total international calls and ration of international total are important factors for domain expert practically practicing protecting the telecommunication frauds. There are misclassification results happened because of false positive and false negative. In telecom fraud detection, the cost of a false negative is more expensive than a false positive because a false positive can be classified correctly after further investigation, but a false negative means that the fraudster has managed to stay undetected and can continue committing fraud. Therefore further research needs to be done to reduce false negative in identifying subscription fraudsters.

(Addis Ababa University, 2020-09-09) Tameru, Wubit; Beshah, Tibebe (PhD)
Trust is a very important element in the success of e-commerce. The lack of customer trust is one of the focused issues today as the world moves toward the advanced information and technology era. This research aims to investigate the major determinates of customers’ trust and tried to propose a framework to build consumers' trust toward e-hailing service. The research examines the factors that determine consumers’ trust by understanding the concept of trust, reviewing several trust-related models, frameworks, and recommended by other scholars. Descriptive statistics and regression analysis were employed to investigate how the respondents perceive the factors to be, to feel trust in e-commerce. The analysis is done using SPSS statistics version 20. Frequencies, percentages, and regression analysis were used for discussion for the questionnaire collected from the respondents. The data were collected through questionnaires using a convenience sampling technique from 384 respondents of e-hailing service users. The findings of this study indicate that Customer service, Perceived Security, Assurance, Reputation, and Familiarity determines consumers' trust are critical factors that significantly determine consumers trust toward e-hailing service. Other factors such as Brand, Website/ Application Quality, and Perceived Privacy also have a close association with trust toward e-hailing services. The proposed trust building framework was evaluated by selected respondents from the participants during the survey. The proposed trust building framework will reduces customers trust issues as well it helps to build and enhance customers’ trust toward e-hailing services. Accordingly, there is a need to implement the proposed framework which will have a major contribution for the electronic transportation sector in Ethiopia.

Enhancing Knowledge Sharing With in Nbi Determinants and Solutions
(Addis Ababa University, 2014-06) Tesfaye, Anteneh; Beshah, Tibebe (PhD)
Knowledge sharing has been identified as the key enabler of knowledge management. To leverage knowledge resources and to support knowledge sharing, organizations are employing knowledge management systems. While knowledge management systems are important, practical implementations have found that technology alone cannot guarantee that knowledge will be shared. The objective of this research study was to examine the determinant factors that promote or discourage knowledge sharing behaviors of individuals with in NBI context and propose a technical and non- technical solutions. Drawing from multiple streams of research including social psychology, organizational learning, knowledge management, information systems and so forth, this research developed an integrated theoretical model and unveiled three sets of critical factors: psychological, organizational and technological that are believed to affect the knowledge sharing behaviors. The posited theoretical model was validated using a field survey of individuals from NBI, the case study area of this research study. The results of the study provide empirical support for the overall structure theorized in the research model. 9 of the 11 hypothesized relationships were supported. Knowledge sharing behavior was predicted by individual’s intention towards knowledge sharing and perceived behavioral control. Knowledge sharing intention in turn was predicted by knowledge workers attitude towards knowledge sharing, subjective norm and perceived behavioral control. The strength of Social network and trust exerted positive effect towards favorable attitude towards knowledge sharing and subjective norms towards knowledge sharing. Perceived organizational incentives and benefits exerted a positive effect towards favorable attitude towards knowledge sharing. The perceptions of loss of knowledge power exerted a negative effect on the attitude. Organizational climate positively influenced knowledge workers subjective norm. Additionally, facilitating tools and technology was positively associated with high levels of perceived behavioral control towards knowledge sharing. Based on the findings, the study discussed implications for theory and practice. Overall, the results of the study advance prior research in the area of knowledge sharing by shedding light on the determinants of knowledge sharing behaviors of individuals. In addition to contributing to theory, XI | P a g e the findings of the study also yield insights for practice. These insights could be used by organizations in developing realistic environments that are conducive to knowledge sharing. Furthermore in the final section the study proposed a prototype knowledge portal that can be used as a common tool to minimize the effects of those factors identified during study through providing an easy means for collaboration, Community of practices, access to valuable knowledge, team building, knowledge sharing, to narrow the physical gap between individuals in organization like NBI and so forth.
Enhancing Patient Satisfaction on Hospital Appointment Scheduling: Using Mobile Technology
(Addis Ababa University, 2020-06-06) Belete, Helina; Beshah, Tibebe (PhD)
Implementing the mobile health System is the priority agenda not only in developed countries but also in many developing countries. To make hospital appointments in our country, Ethiopia, a patient needs to directly go to healthcare and wait until doctors are available. This procedure affects the patient’s experience. Since there are few studies on patient satisfaction, we need patient satisfaction study and country based (local) application. The objective of this study is to investigate and design a mobile-based solution that can enhance the patient experience while visiting Healthcare. This app is aimed to reduce the exhaust patients’ faces on scheduling appointments. Design Science Approach is adopted in doing this research, which is a process model, consisting of six activities in a nominal sequence. Data was collected based on a survey collected from participants using semi-structured interviews. Using a narrative approach, we interpreted stories told by participants to determine the requirements of the new system. In translating user requirements into diagrammatic representation, we applied analysis and design models, UML diagrams such as Use Case and Sequence Diagrams and Class Diagram. The result of this study shows that patients satisfaction increases when factors affecting patient experiences are improved such as patients' expectations, waiting time, consulting time, and arrival time. Additionally, in this work community-based appointment scheduling system for patients is proposed. The User Interface of the prototype is presented using screenshots to show and demonstrate the system. Smart Doctors Appointment and Prescription System has no functionality for prediction of patient consulting time and community concern like no function of location information and local language-based which are the major challenges for this study. Therefore, we inferred the need for analyzing patient requirements and the development of mobile applications that overcomes the problems and play a vital role to provide healthcare services timely, in an organized way.
Enhancing Service Delivery Capability of it- Service Desk: the Case of Ethio Telecom
(Addis Ababa University, 2020-06-06) Terefe, Yodit; Beshah, Tibebe (PhD)
People nowadays need different telecom services like telephone network (voice, instant messaging), radio broadcasting system, computer networks, internet etc. Ethio telecom provides this sort of services in Ethiopia. This company creates the IT service desk section to address the IT related concerns of the employee and maintain their business continuity at the back. Most IT service desk enquiries are simple and routine. Analysts overwhelmed by supporting this inquiry have insufficient time to provide support at a high level. Simple and routine inquiries are problems that the user themselves can address if adequate information is given. This work will enhance the IT service desk's service delivery capability by combining the existing system with a platform of self-help resources. A survey was carried out to classify simple and routine inquiries. The questionnaire is adopted from the "information technology help desk to identify the classification of simple and routine inquiries " in Austria (2007) and has been modified to meet the research questions. The analysis result shows that more than 50% of the incoming inquiries recorded in the IT service desk are simple and routine. The result shows that a decrease in incoming inquiry would be expected if sufficient guidance, such as training, online documents, and integration of the current system with the portal of self-help support is provided. A prototype was developed to demonstrate the ability to provide a solution for both simple and routine inquiries. If the user requests simple and routine enquiries, the system redirect him/her to another page where they can solve the problem without interacting to any IT professional. Evaluation result of the prototype show that the user interface is 94 percent attractive, 97.6 effective in improving service delivery ,96 percent users satisfied with the self-support concept,99 percent risk-free and 94 percent context coverage. So, it really enhances the service delivery process. Keywords: IT service desk, Support model, simple and routine inquiries

(Addis Ababa University, 2009-10) Hailu, Digajara; Beshah, Tibebe (PhD)
This research was conducted to explore the trends, challenges and opportunities of Tourism Information Systems (TIS) in Ethiopia with a special emphasis on tourism websites. Two surveys were conducted: while the first one dealt with tourism institutions, the second dealt with tourists. In the first case questionnaires, mainly, and interviews, to fill gaps, were employed as methods of data collection. In the second survey only questionnaires were used because of the large number of visitors. The data gathered were analyzed using the Statistical Product and Service Solutions (SPSS) and simple descriptive statistics like the mode (frequency) was used to explain the empirical findings. Tables were used for data presentation, based on which comparisons were made. The results of the study reveal that, embarking with the then “Thirteen Months of Sunshine” manual ad sign; the Ethiopian TIS is now experiencing the opportunities presented by modern information technology such as websites. There is a promising awareness about modern information systems among the businesses, but in its infancy. Major challenges identified by the study include: gaps between businesses’ and the tourists’ perceptions about the local tourism websites, missing website components and inability to fully harness the Internet. Yet, there are some opportunities created by the Web for such tourism businesses. The study also provides some recommendations towards TIS for tourism businesses in the nation.

Result: - The study revealed that 53% of the study participants frequently share their knowledge. More than half of the participants report the absence of motivational schema or system and 60% of the respondents have high motivational level. Multivariate analysis result indicates that knowledge sharing of the health care professionals is by 2.87 score more in the presence of information communication technology with (AOR=2.87; 95% CI= (1.18, 7.007)). Therefore, information communication technology found to be an independent predictor for knowledge sharing. Based on the findings of the study a framework that support the knowledge flow process was proposed. Therefore, framework is designed to enable information technology plays its part in improving knowledge sharing practice in the hospital to improve the quality of health care service. Conclusion: - The study shows that most of the respondents were aware of the importance of knowledge sharing, engage in active knowledge sharing practice and use face to face communication and observation as knowledge sharing mechanism in the hospital. And also the study indicate availability of ICT as independent predictor of knowledge sharing.
Identifying Ethiopian National Mining Cadastre System (Enmcs) Post Implementation Success Factors the Case of Ministry of Mines of Ethiopia
(Addis Ababa University, 2021-06-11) Assefa, Fitsum; Beshah, Tibebe (PhD)
With the aim of bringing transparency and efficiency to its mining sector, Ethiopia implemented a web based mineral licensing and administration system named FlexiCadastre with the support of the world bank back in 2008. However, the post implementation utilization of the FlexiCadastre is inconsistent between federal and regional mineral licensing bureaus and did not bring the intended business benefit. The strategic direction put forward for the mining sector of Ethiopia in the second growth and transformation plan (GTPII) is attracting foreign direct investment to the mining sector. In an attempt to revive a decline in foreign applicants Ministry of Mines and Petroleum (MoMP) upgraded FlexiCadastre System to Ethiopian National Mining Cadastre System (ENMCS) with an e-government portal to improve the mineral licensing and administration‟s transparency and efficiency which in turn is believed to boost investor confidence. The ENMCS has gone live in December 2019. However, with no empirical study conducted on the post implementation challenges that resulted in the underutilization of the FlexiCadastre and the scarcity of studies on land administration system post implementation critical success factors will makes it difficult to objectively identify factors that will improve the post implementation utilization of the ENMCS. The objective of this study is to identify technical, organizational and operational factors that affect the post implementation utilization of ENMCS and based on the identified issues to propose a high level ENMCS post implementation utilization improvement organizational guide. This research is a case study where a combination of quantitative and qualitative methods has been employed to collect and analyze data. The study‟s research model is proposed after extensive literature review on land administration system (LAS) and ERP post implementation related literatures. The proposed research model that is based on the literature review indicated three major themes; Technical, Organizational and Operational themes that affect the post implementation utilization of the ENMCS. A survey questionnaire that is adopted from literatures and contextualized to the case of ENMCS to quantitatively measure the constructs under the three themes is administered to the population of the study that is 73 federal and regional level ENMCS users. To triangulate the quantitative method findings of the study a qualitative method is applied by administering semi-structured interviews with purposively selected two federal and three regional mineral licensing and administration directors. iv Descriptive and inferential analysis has been conducted on the quantitative data of the study using SPSS. The interview findings of the study are arranged into major themes and narrated. The descriptive statistics of the study revealed that 50% of the respondents disagreed on top management having a discussion with them on the impact of ENMCS on their work. The vast majority of survey respondents, 89%, disagreed being made aware of ENMCS upgrades and unavailability through email. The inferential statistics revealed that organizational and operational issues to have a significant positive relationship with the ENMCS perceived usefulness and overall satisfaction of using the ENMCS. The interview findings triangulate the descriptive and inferential statistics findings of the study as they revealed the organizational theme construct of top management commitment having a crosscutting impact on all the constructs of the technical, organizational operational themes. The organizational guide is proposed based on the findings of the study for the constructs that are critical for improving the post implementation utilization of the ENMCS using the people, process and technology concept as a guide.
Information systems development outsourcing management in Ethiopia: the case of the Ethiopian Telecommunications Corporation.
(Addis Ababa University, 2009-10) Atinaf, Muluneh; Beshah, Tibebe (PhD)
Information systems/technology outsourcing is considered as an approach for information systems/technology management by chief information officers and organizations. Thus it is given due attention by various organizations and management because of the advantages it brings to them. Despite the advantages it brings, IS/IT outsourcing faces problems/challenges and risks at any point in the process that may even lead to failure before its maturity. However, all theses issues are not studied in the case of Ethiopia. This study thus aims to empirically assess how IS/IT outsourcing is managed in Ethiopia, specifically at the Ethiopian Telecommunications Corporation. A case study approach considering a currently outsourced information systems development project at the corporation is followed so that a better and detailed understanding of the subject can be developed. Furthermore this research tried to identify the problems/challenges that the corporation faced during outsourcing and the possible causes of the problems. The research employed a qualitative research methodology, and hence interview and document analysis were major data collection methodologies used. The data collected is analysed as per research questions and objectives of the study. Finally, from the data analysis it is clearly indicated that the outsourcing organization has failed to meet its schedule, cost, requirements, and customer service objectives. The major causes for these problems were lack of detailed requirements from the beginning, lack of detail in the SLAs, lack of previous experience in software outsourcing management.

(Addis Ababa University, 2017-06) Kebede, Debritu; Beshah, Tibebe (PhD)
Background: The laboratory information system is a data processing and dissemination system used in the laboratory to deliver accurate and understandable results within a reasonable timescale as requested by physicians. The problem of manual system used in Arada health center makes it difficult to provide efficient and quality health service data and the lack of integration of data, organized test result, different reporting formats and long turnaround time brings about delay of treatment and poor data quality. Objective: The objective of this project is to design and develop laboratory information system for Arada health center. Method: This used a combination of qualitative purposive method and object-oriented system analysis and design methodology with the incremental approach which includes requirement collection, analysis and design phases. The design emphasized the structure and behavior of systems, which interacts different objects or class within the system. Requirement was collected using the following tools (interview and relevant document review techniques). Analysis and design of the proposed system was performed using the Use Case Diagram, Activity Diagrams, Class Diagrams, Deployment Diagram and Persistent Model. Result: Considering the importance of the Laboratory Information System for the health center the researcher has identified the problem of ordering a number of laboratory test papers for the single patient, the long time for data retrieval, transcription error and illegible hand writing that has been encountered while using paper based documentation. After identification of the problem, laboratory information system has been developed and tasted so as to solve the identified problems. Conclusion: The developed system solves the problem of data integration and can capture a number of laboratory test order forms with a single interface used by the physician and the laboratory technician in the exchange of information for ordering laboratory tests and receiving the results back to the physician. This makes the laboratory data to be easily manageable and accessible by health professionals and decision makers. Usability test has been done and discussion was made with users in order to determine functionality, effectiveness and acceptability of the project and almost all of the respondents accepted the prototype. Regarding the functionality, the system produces reliable data and hence avoids the problem that used to occur by the manual system.
Maturity of Information Technology Governance in the Financial Sector of Ethiopia; A Comparative Study
(Addis Ababa University, 2016-06-03) Mekonenn, Tagel; Beshah, Tibebe (PhD)
Information Technology (IT) changes significantly the way we live, communicate and do business. As a result there are few companies that can afford the luxury of ignoring IT. This pervasive use of technology has created a critical dependency on IT that calls for a specific focus on IT Governance. The aim of this study was to investigate maturity of IT Governance in the financial sector of Ethiopia. Mainly survey methodology was employed to investigate the perceived importance and maturity of IT Governance practices in the financial sector of Ethiopia in terms of IT Governance structure, processes and relational mechanism. Using simple random sampling, two private banks (Dashen Bank and Zemen Bank) and two private insurance companies (National Insurance Company of Ethiopia and Nile Insurance) were selected randomly. Purposive sampling was used to include Commercial Bank of Ethiopia and Ethiopian Insurance Company since one of the objectives of the research was comparing IT Governance maturity between private and public financial institutions. A total of 96 self administered questionnaires were distributed targeting senior business and IT leaders and return rate of 80% was achieved. Regarding data analysis, the quantitative data was analyzed using SPSS and the qualitative data was presented based on predefined themes. Finally the survey result was complemented and triangulated with interview result and document review to answer the research questions. Importance of IT Governance in the financial sector of Ethiopia was rated 4.2 based on a scale from 0(strongly disagree) to 5(strongly agree). This shows that there is a strong consensus between business and IT leaders on the Importance of IT Governance practices. In spite of this keenness, the actual IT Governance maturity was rated 1.2 (level 1) based on generic maturity scale from 0(non-existence) to 5(optimized) i.e. IT Governance issues were recognized but practiced in an informal and ad hoc basis with little or no evidence of standardization. The survey result also shows that, relatively privately owned financial institutions (1.3) reached better level of IT Governance maturity than that of publicly owned (0.94) likewise though IT Governance maturity was rated at initial stage (level 1) in the financial sector of Ethiopia, the banking sector (1.4) reached better level of maturity than the insurance sector (0.7) based on generic maturity scale from 0(non-existence) to 5(optimized) Regarding IT decision making right, IT leaders in the banking sector play superior role than their peers in the insurance sector. The prevalent IT Governance archetype (locus of IT decision making authority) in the banking sector was a combination of IT Monopoly (IT executives has exclusive decision making right on IT Architecture and Infrastructure) and IT Duopoly (IT leaders shares decision making right with business executives on IT principle, business application needs and IT investment and prioritization) whereas it was Business Monarch in the insurance sector i.e. IT leaders have only input rights and the decision right was exclusively held by business executives. Furthermore, among IT Governance mechanisms, relatively IT Governance structure was rated as more important as well as mature than that of IT Governance Processes and Relational mechanism. On the basis of the above results, it can be concluded that, IT Governance maturity is at initial stage (level 1) in the financial sector of Ethiopia. So, to reach desired level of IT Governance maturity and to get the best out of IT investment, financial institutions have to start implementing formal IT Governance which fits to their business strategy and culture by mixing-and-matching elements of existing frameworks.
The Potential of Knowledge-Based Systems in Assisting the Justice System: The Case of Ethiopian Labor Law
(Addis Ababa University, 2010-06) Demmelash, Yihenew; Beshah, Tibebe (PhD)
Modern information and communication technology is revolutionizing how courts function, reducing backlogs by speeding up case resolutions and improving citizen access to trial proceedings and disposition. Ethiopia’s system of justice has suffered from long delays that undermined public confidence in the rule of law and imperiled rights granted under the Constitution. Labor law, that governs the employer-employee relationship, is an area which can potentially benefit much from ICT. This study examines the existing practice in the domain of Ethiopian labor law and identifies the most problematic parts of the law. A prototype legal knowledge based system, which is a combination of a rule-based and case-based reasoning mechanism is then developed with the objective of addressing the limitations of the current practice. The knowledge based system provides advice on the most prominent areas of the labor law. This will be very useful for meeting the increasing demands of court clients for speedy and quality decisions. The prototype KBS developed combines a case-based legal reasoning with a rule-based one to address those parts of the law which requires different type of treatment. Areas of the law in which the law provide clear rules to handle cases will be treated using the rule-based module of the system, while the case-based module addresses those areas which are left to the discretion of the judge. The system’s output was tested against that of a set of decided cases. This allowed the system’s reasoning to be tested. Testing indicates that using a rule-based approach to reason with legislation and a case based reasoning to reason with cases is appropriate.

The purpose of this research is to look at the practices and challenges of agile development methodology in Ethiopian airlines and come up with a proposed guide to address the identified challenges. The overall approach of this study was a case study in which data was collected and analyzed using a combination of quantitative and qualitative methodologies. A research guideline was developed based on a thorough literature analyses, and findings of an empirical data. The contents of the survey questionnaires and interview outlines were constructed based on the established research objectives, with some adaptations from available literature and new ones developed as needed. The study's quantitative component included 72 respondents from Ethiopian airlines application development teams. Each with their own job title, role, and work experience. Interviews were also conducted to obtain data from five members of the airline's IT directors and managers in the qualitative study. Furthermore, document analysis was used as a secondary source of data in order to gather additional information and triangulate the findings. Using the SPSS software program, the quantitative data were analyzed using appropriate descriptive approaches. The qualitative data was examined with open codding approaches. Findings revealed that Team work related practices were not properly experienced and team work related challenges were the most important predictors of agile development methodology implementation. Expert validation and descriptive approaches were utilized to assess the study's outcome (proposed guideline) in this study. As a result, expert validation was obtained through company mail and survey questionnaires. The proposed framework receives a 4.45 total rating, putting it in the "Agreement" category. Hence, the research process and result of this study is believed to be valid which indicates the usability and applicability of the output of the study. This study is expected to yield insights that will help Ethiopian airlines application developers so as to better understand and implement agile methodology. Finally, it is suggested that the proposed guideline be implemented by prioritizing the team work theme as a priority aim in order to sustain agile methodology implementation.
Problems and Challenges on Addis Ababa Land and Infrastructure Management: Towards an Information System Strategy
(Addis Ababa University, 2018-09-01) Bekele, Fasil; Beshah, Tibebe (PhD)
Information is a powerful resource in this ―information age‖. The form and tools to exchange information and data from human civilization and industrial era and to current time is changing drastically. Information system obviously played the vital role here. Most cities and municipalities are currently adopting information technologies in their various activities to achieve their targeted goals and objectives. Addis Ababa City Government, as well, currently launched a GIS based land management information system and using it to register owned land plots of the city. However, the general land and infrastructure management is suffering from different problems and challenges. One of these problems and challenges is the crossing over of infrastructures amongst the infrastructure. This crossing over impedes the development of infrastructures of the city and also incurs a significant lose in different types of resources. This research attempted to explore and empirically evidence those problems and challenges, the major sources as well and propose an Information System Strategy as a solution. Mixed methods, in which qualitative and quantitative approaches have been employed consecutively in this research with a sequential exploratory strategy. In due course, the problems were found to be renowned and generated basically from lack of exhaustive information about each of the infrastructures, poor and traditional way of communication and information exchange, and selfgoal centeredness of the bureaus. Eventually, it is divulged that the problems and challenges of the crossing over can be resolved by formulating and implementing an Information System Strategy. The key findings that the Information System Strategy solution should comprise are acquiring comprehensive information, embracing them before getting in to the physical works, creating integration with other concerned organs including the involvement of both regional and federal governments. Therefore, from the findings and results of the analysis of the data obtained from informal discussion with the executives and experts in the area, interview and documents review, a high level IS Strategy is proposed and evaluated against utilities it need to posses with the experts in the area and IT professionals in the organizations.
