Strategic release planning (road-mapping) is an important phase of requirements engineering process performed at product level. It is concerned with selection and assignment of requirements in sequences of releases such that important technical and resource constraints are fulfilled. It is always considered difficult to form a strategic release plan due to varying constraints and uncertainties. In this regard, different strategic release planning models have been presented in academia and different methods are being used in Industry. In this thesis, strategic release planning models presented in academia and some methods of strategic release planning being used in Industry are identified. The contributions of these models are also provided in the thesis. A systematic review has been performed to know strategic release planning models in academia. The aim of systematic review is to present fair evaluation of research concerning strategic release planning models. Through systematic review, requirements selection factors considered by a model, validation details of model and a model’s usefulness for bespoke and market-driven development are summarized. Moreover two organizations have been interviewed to know strategic release planning models being used in Industry in addition to the ones presented in academia. Similarly contribution of models being used in Industry is provided by logging details of requirements selection factors, validation details and usefulness for bespoke and market-driven software development of each model / process of Industry. Based on systematic review and industrial interviews’ results, a list of common requirements selection factors (considered by models of academia and Industry) is provided. Some general recommendations have been given for research in academia on strategic release planning models after analysis of systematic review and industrial interviews’ results. / Strategisk release planering (väg-kartläggning) är en viktig fas av requirements engineering process som utförs på produktnivå. Det handlar om urval och tilldelning av kraven i sekvenser av utsläpp så att viktiga tekniska och resurser är uppfyllda. Det är alltid anses svårt att skapa en strategisk release planen på grund av olika begränsningar och osäkerheter. I detta avseende olika strategiska release planering modeller har presenterats i den akademiska världen och olika metoder som används inom industrin. I denna avhandling, strategisk release planering modeller i den akademiska världen och vissa metoder för strategisk release planering som används inom industrin har identifierats. Bidraget från dessa modeller är också i avhandlingen. En systematisk genomgång har gjorts att veta strategisk release planering modeller i den akademiska världen. Syftet med systematisk översyn är att presentera en rättvis utvärdering av forskning om strategisk release planering modeller. Genom systematisk genomgång, krav urval faktorer betraktas som en modell, validering uppgifter om modell och en modell nyttan för beställda och marknadsdriven utveckling sammanfattas. Dessutom två organisationer som har intervjuats att veta strategisk release planering modeller som används inom industrin och utöver de åtgärder som presenteras i den akademiska världen. Likaså bidrag av modeller som används inom industrin ges genom att logga information om kraven urval faktorer, validering information och nytta för den beställda och marknadsdrivna mjukvaruutvecklingen av varje modell/process industri. Baserat på systematisk genomgång och industriell intervjuer resultat, en förteckning över gemensamma krav urval faktorer (som av modeller av den akademiska världen och industrin) tillhandahålls. Några allmänna rekommendationer har fått för forskning i den akademiska världen på strategisk release planering modeller efter analys av systematisk översyn och industriell intervjuer resultat. / +46765541016, +46762920070

The rapid growth of universities in the Least Developing Countries (LDCs) is aimed at enhancing access to tertiary education, which has resulted in a sharp increase in the enrolment rate. However, the quantitative increase has been marred with a correspondingly continuous decline in the quality of education. This is attributed to a wide range of limiting factors mainly classified as institutional problems. Some of these problems include a shortage of resources, limited skills and incompetent human capital, lack of ICT infrastructure, and the ineffective use of existing ICT resources. These problems and others have adversely affected how national education and research network can improve research output and quality of education. In this study, a survey, in the form of an exploratory quantitative research design is used. A descriptive non-experimental quantitative approach was also chosen, and a questionnaire was administered to approximately one hundred and seventy-two (172) participants drawn from twenty-nine (29) Ethiopian Public Universities. The results of the analysis show that the study variables namely NREN service for education, EthERNet, electronic device and research output have a significant and positive impact on the Quality of Education (QE) to differing degrees. Also, the study variables such as NREN service for research, high-performance computing, and remote computing facilities indicated that they had a significant and positive impact on Research Output (RO) to differing degrees. The study explored the impact of EthERNet in improving the quality of education and research output by examining the existing network infrastructure and NREN services. The study employed the use of the Actor-Network Theory (ANT) to assess the existing network infrastructure and NREN services to determine that a reliable network can improve the quality of education and research output. Besides, Structural Equation Model (SEM) was used to identify the positive and negative factors that impact on the roles, relationships, and formation of quality of education and research output. Furthermore, a three-step design science approach was applied to propose and justify the theoretical framework, which is used as a base to develop a service portfolio and roadmap conceived to design the required NREN service for EthERNet. This research contributed to the body of knowledge by finding the missing link between the quality of education and research outputs. From a theoretical perspective, the research contributed a theoretical framework by developing the construct and their measures that can be used in assessing the adoption and usage of technology. Furthermore, the study contributes to the literature by demonstrating an analytical process which could be used as a guide for future NREN service requirement to improve the quality of education and research output with the existing findings being used as a reference point. / School of Computing / Ph.
