O objetivo deste trabalho é estudar o processo de adoção do Software Livre na Universidade de São Paulo. É de especial interesse o estudo dos aspectos culturais e organizacionais que contribuíram para a adoção do Software Livre entre os administradores de sistemas. O estudo de adoção, não se limitou à adoção individual, mas se estendeu à adoção organizacional uma vez que a adoção de inovações tecnológicas em organizações difere de modo especial da adoção individual. A adoção organizacional aborda aspectos como a extensão do uso da inovação e, o quão profundamente o uso da tecnologia altera processos, estruturas e cultura organizacional. O fenômeno de adoção na Universidade revela-se particularmente importante por ter se tratado da adoção de uma nova tecnologia, em grande escala e bem-sucedida. Esta pesquisa estuda quais são os fatores condicionantes e os que favoreceram a adoção da nova tecnologia, bem como o contexto social e cultural desta adoção em diferentes Unidades da USP. / The objective of this work is to study the adoption of Free Software in the University of São Paulo. It is of special interest the study of the cultural and organizational aspects that contributed to the adoption of the Free Software among the systems administrators. The adoption study, was not limited to the individual adoption, but it extended to the organizational adoption once the adoption of technological innovations in organizations differs in special ways from the individual adoption. The organizational adoption examines aspects as the extension of the use of the innovation and, how deeply the use of the technology affects processes, structures and organizational culture. The adoption phenomenon in the University is particularly important for having it been a voluntary adoption of a new technology, in great scale and well succeeded. This research studies which factors restricted or favored the adoption of the new technology, as well as the social and cultural context of this adoption in different Units of USP

<p>The development of open source software has gone from a model characterized by skilled software developers that developed open source software for their own interest and their own needs to a model that is more business friendly and more attractive for companies and organizations. One new business model for open source software is the professional open source software model or OSS 2.0. The business model includes three roles: the open source project, the professional open source company and the user. This dissertation studies the relationship between these three roles and focuses on the development of the user role and how it may develop for a new user in a specific OSS ecosystem.</p><p>The roles in the eco system that has been studied are taken by the open source project Alfresco, the professional open source company Redpill and a user from a large international company, without any previous experience of open source software or the business model of professional open source. The result of the study showed a well developed eco system between the open source project and the professional open source company but a need of more information about the user’s role in it. Open source software is still seen by the user as an unsafe and unsecure alternative to the proprietary software available and more information about the business model of professional open source software and how the user can interact and influence the eco system is still needed.</p>

Context： Software evolution comes with the increasing growth of software applications both in size and complexity. Unlike the software maintenance, software evolution addresses more on the adaption of the new fast-changing requirements. Then the term of “software evolvability” comes with its importance for evaluating the evolution status of the software. However, it is not clearly identified especially in the context of open source software (OSS). Besides the most studies are about the description of software evolvability as a quality attribute, and very few research have done on the measurement of software evolvability during the software evolution process. Objectives： In this study we perform an in-depth investigation on identification of the OSS evolvability, and figure out the appropriate metrics used for measuring the OSS evolvability. Based on that we finally proposed the open source software evolvability measurement framework (OSEM) which could be used for measuring the software evolvability generally in an OSS context. Methods： At first, we conducted a literature review by combining backward snowballing search with systematic database search. Two research questions which are RQ1 and RQ2 are proposed for helping us to retrieve the key information for building the needed framework. Then we performed a case study on VLC media player (an OSS project) to validate the processes of the proposed framework. Results： Based on literature we could explicitly identify the OSS evolvability, and figure out the differences of software evolvability addressed in OSS context and non OSS context (e.g, the traceability refers to documentation in non OSS context, however in OSS context it refers to the release version of OSS project). Besides we also fulfill the evolvability measuring method by addressing the process of prioritization of evolvability sub-characteristics. In the end we implement the OSEM framework on VLC media player and get the well documented results which are clearly presented and easy to understand. Such results could be taken by the VLC developers as an input for the design and development of the VLC. Conclusions: We conclude that the open source software measurement framework (OSEM) is applicable, based on the time we spent on the case of VLC media player it is quite fast and efficient to use such framework. The results from the conduction of this framework are documented well and very clear for OSS users/developers to follow.

This exploratory research examined an information policy formation process for the adoption of open source software (OSS) in Uganda. Grounded in a pragmatist tradition, this theoretical and empirical study pursued a qualitative research approach with a triangulation of theoretical concepts, data collection, and analysis techniques in an iterative and interactive process. The design provided a powerful context to develop and conduct field activities in Kampala with a purposeful sample of 22 participants, 20 in interviews and 5 in a focus group discussion. The research design enhanced consistency in the evidence from the data, increased robustness in the results, and confidence in the findings. The results highlighted a vibrant ICT sector in Uganda, underlined the multiple stakeholders and their competing interests in the policy, revealed a lack of consensus between the government and OSS promoters on the meaning of OSS, and illuminated the benefits in the OSS model over proprietary software. The stakeholders' conflicting perceptions appear to be too far apart to allow meaningful progress and are derailing the policy. Unless their conflicting perceptions are resolved, the OSS policy will continue stagnating. The study fills critical information gaps in Uganda’s policy formation processes, provides timely and relevant information to holistically understand a complex policy formation stage to enable stakeholders to resolve their impasse and enact a law to embrace OSS. It breaks ground in information policy research in framing policy formation processes for new ICTs, such as OSS, as ideologically-oriented. The findings offer ideas to scholars and African countries to draw applicable lessons.

South Africa has shown an increased interest and awareness of Open Source Software (OSS) in the past decade. One of the reasons for this was the support from the Shuttleworth Foundation for Open Source initiatives. Migrating to OSS is a difficult and time consuming activity that should not be underestimated by the migration team. Careful planning and roll-out procedures should be in place before one commence on this journey. Process reference models are used in different fields to capture the generic process flow of activities. For the OSS domain, no process reference models could be found for migration purposes. Therefore, this study has as aim the suggestion of an initial set of process reference models for an organisational OSS migration. These process reference models were identified by capturing the process models for a case study that entailed the migration of the CSIR software systems and desktops from proprietary to OSS. From this set of process models, the migration processes were identified and refined to a set of suggested process reference models for organisational OSS migrations. This set of process reference models are useful to determine the processes necessary for organisations considering migrating to OSS. The study is divided into four research questions, where the first focusses on use and value of process reference models and the second on what is already known about OSS migration processes. The third deals with key processes within an organisational open source migration (OOSM) and the last with process reference models for an OOSM. For the first research question, the use and value of process reference models and the usefulness of utilising process reference models is discussed as well as using process models as a modelling tool to identify and capture processes. For the second research question, a summary is provided of what we know about OSS migration processes and a description about what the researcher and others have learnt about OSS, OSS migrations, process reference models, the process and its structure. For the third research question, the key processes within an OOSM is discussed as well as all the processes that took place during the OSS migration project from basic administrative processes to complex processes, from the beginning of the project until its completion. Lastly, for the fourth research question, process reference models that are essential for an OOSM and possible generic migration process models bound to reoccur are identified by the researcher and validated using a focus group discussion. / M.Tech.
