Social Network Structure as a Critical Success Condition for Open Source Software Project Communities

Hinds, David 13 March 2008 (has links)
In recent years, a surprising new phenomenon has emerged in which globally-distributed online communities collaborate to create useful and sophisticated computer software. These open source software groups are comprised of generally unaffiliated individuals and organizations who work in a seemingly chaotic fashion and who participate on a voluntary basis without direct financial incentive. The purpose of this research is to investigate the relationship between the social network structure of these intriguing groups and their level of output and activity, where social network structure is defined as 1) closure or connectedness within the group, 2) bridging ties which extend outside of the group, and 3) leader centrality within the group. Based on well-tested theories of social capital and centrality in teams, propositions were formulated which suggest that social network structures associated with successful open source software project communities will exhibit high levels of bridging and moderate levels of closure and leader centrality. The research setting was the SourceForge hosting organization and a study population of 143 project communities was identified. Independent variables included measures of closure and leader centrality defined over conversational ties, along with measures of bridging defined over membership ties. Dependent variables included source code commits and software releases for community output, and software downloads and project site page views for community activity. A cross-sectional study design was used and archival data were extracted and aggregated for the two-year period following the first release of project software. The resulting compiled variables were analyzed using multiple linear and quadratic regressions, controlling for group size and conversational volume. Contrary to theory-based expectations, the surprising results showed that successful project groups exhibited low levels of closure and that the levels of bridging and leader centrality were not important factors of success. These findings suggest that the creation and use of open source software may represent a fundamentally new socio-technical development process which disrupts the team paradigm and which triggers the need for building new theories of collaborative development. These new theories could point towards the broader application of open source methods for the creation of knowledge-based products other than software.

Localization and Terminometrics: Measuring the Impact of User Involvement on Terminology

Bilgen, Baris January 2016 (has links)
Online collaborative translation has received increased attention from Translation Studies, mostly with a focus on explaining the various models it exhibits and the factors that shape these models. This study takes a new perspective on this phenomenon by focusing on its outcome through the lens of terminology. A terminometric analysis is carried out on the terminology used in the discussions of Francophone users on online forums of the Ubuntu-Québec open-source software community. The implantation of terms used in the forums and those stored in a selection of major term banks is examined with the objective of identifying potential correlations between term implantation and term formation patterns. The examination indicates that most terms formed through the use and modification of existing linguistic resources have higher implantation rates than terms formed through the creation of new lexical items. A new avenue of terminometric research is introduced by shifting the focus from the institution to the community, aligning with the global shift in content production and distribution. The study provides insight into online collaboration in the context of localization and points out correlations between term formation patterns and term implantation. These observations can mark a starting point for terminological decision-making that is informed by user behaviour and may thus improve the reception of localized content by adapting to users' terminological expectations.

Výběr a implementace open source nástroje pro řízení portfolia projektů / Selection and implementation of open source project and portfolio management tool

Kučera, Jan January 2009 (has links)
Companies and other organizations have to change and adapt their strategies and redefine their goals constantly. Actions and steps that are needed in order to achieve the defined goals and to realize the change are often executed in a form of a project. There is no doubt that projects need to be managed in an appropriate way. In organizations where there are more than one project executed in parallel and other projects are being planned or proposed at the same time it is necessary to manage not only the individual projects but the entire portfolio of projects and programmes. Portfolio management is needed to ensure that the selected projects are best aligned with the defined goals and the strategy but this requires an analysis of a large amount of data about current and upcoming projects or about available resources and their utilization. It is not always easy to get all required data and to perform the analysis. This is the reason why deployment of some project and portfolio management software tool should be considered. This thesis deals with a search for suitable open source project and portfolio management tools and with assessment of costs and benefits of deployment of selected open source tool in a hypothetical IT company. The goal of this thesis is to define the term project and portfolio management tool and to find at least five open source tools of this type that are suitable for deployment in an organization. At least one of these tools should be suitable for deployment in the IT company. Another goal is comparison of features and functionality provided by the open source tools with functionality provided by the robust proprietary project and portfolio management solution deployed on premise and with one solution offered in the Software-as-a-Service model. Creation of a business case dealing with implementation of the selected open source tool is the last goal of this thesis. Identification and description of available open source tools and comparison of these tools with representatives of the robust project and portfolio management tools developed and distributed in models different from open source are considered the main benefits of this thesis. The terms "open source software" and "project and portfolio management tool" are defined in the first part of this work. The definition of terms is followed by the definition of the overall approach to the assessment of the open source tools which involves definition of assessment criteria and obligatory requirements. Next part of the work is dedicated to the selection of the open source tools that are suitable for deployment in an organization and which represent candidates for project and portfolio management tools. Assessment of these tools using the defined criteria is performed as the next step which is followed by the comparison with representatives of proprietary project and portfolio management tools. Last part of the work is dedicated to the business case which deals with deployment of the selected open source tool. This work concludes with discussion whether the defined goals were met or not, and with the summary of the results.

Návrh a implementace integrovaného testovacího nástroje / Design and implementation of the integrated testing tool

Munzarová, Helena January 2014 (has links)
The purpose of this thesis is to design and implement integration interface, which represents the core of the Integrated testing tool. Integrated testing tool provides support in the whole process of software testing. This support involves requirement specification and management of the corresponding tests, bug management and creation and execution of automated testing scripts. Integrated testing tool uses existing open-source tools to provide this functionality. The communication of these tools is provided by the integration interface, implementation of which is the purpose of this thesis. Currently there is no so complex open-source solution in the testing area, Integrated testing tool endeavours to fill this gap. The tool is being developed within the activity of the competence centre Software Quality Assurance at the University of Economics in Prague. The analytical phase of the development is described in the diploma thesis written by Bc. Jan Ženíšek Project of the development of Integrated testing tool.

Selection and implementation of open source tool for project portfolio management / Výběr a implementace open source nástroje pro řízení portfolia projektů

Marek, Jan January 2016 (has links)
Methods and ways of implementation of changes and innovations in companies through project management are in today's society very well established. There exists methodologies, techniques and tools for the management of individual projects. However in a role of project manager, I very often faced the fact that companies are performing the project portfolio management in very intuitive way. This in itself leads to failed and prematurely terminated projects, initiation of the wrong projects or realisation of correct projects, but at the wrong time. Very often I have also recognized, that there is lack of awareness of fact, that there are also Open Source applications that can help with the organization's portfolio. This thesis deals with the definition of requirements, search and selection of proper OSS application and subsequent implementation. In the first part of this thesis I prepare a theoretical framework about PPM, and on that basis then identify and verify a set of requirements for selection of right OSS PPM application. The next section of thesis describes searching for suitable applications from a variety of sources, assessment against the requirements and the final selection. In the last part the implementation project is drafted, which aims to serve other colleagues in project management as one of the possible implementation paths. The outputs are then continuously confronted with experts in matter of projects and project management in the field of IT in order to maximize symbiosis between theory and real life experiences. Virtually every project management methodology defines the collection of already-proven techniques, best practices or lessons learned from the previous similar implementations. The main contribution of this thesis I see in fact that it contains not only the design of the project implementation, but also describes a logical path, what leads to the result. Therefore this thesis could be used as a base or discussed best practice, when a project of implementation of PPM application in place.

Schmidt, Róbert January 2016 (has links)
The main goal of master thesis is to analyze and propose possible low cost Business Intelligence solution with open source technologies and comparison of available tools for implementation in middle size company. We compare Pentaho and Jaspersoft tools implemented on local hardware and cloud environment with Microsoft Azure services. The theoretical part focuses mainly on understanding the business intelligence and its architecture, because architecture is an important part of the work. Actual tools are designed as stand alone modules for specific activities in the business intelligence lifecycle. Low cost tools are often connected with open source technologies and cloud computing. This part of the work contains explanation of these terms and their advantages and disadvantages for our chosen target group of companies. The analytical part includes defined parameters by which it is conducted analysis of tools and their comparison. Business Intelligence solutions are divided according to arcitectural layers. The evaluation criteria are divided into financial, technical and user category. In conclusion, chosen tools are compared and evaluated. The main contribution of this thesis is comparison of open source business intelligence tools for implementation in middle size company. According to the EU directive, middle size company does not exceed 250 employees or profit is less than 50 million euros. The reader can compare the different solutions and their pitfalls or shortcomings that could be critical for the implementation.

Modifiera Mera : En studie om modding och open source, och hur det bidrar till en mer engagerad online community.

Jonas, Björn, Elmedin, Grahovic January 2017 (has links)
I denna uppsats studeras Steams forum där fyra olika spel-communities jämförs med varandra. Det som skiljer dessa spel från varandra är att två av dem är open source och de två andra är inte det. Open source innebär att det går att modifiera spelet utifrån egna preferenser med tillåtelse från spelutvecklaren. Syftet med denna uppsatsen är att mäta engagemang på steams forum genom att analysera forumtrådar. Med hjälp av en kvantitativ innehållsanalys så kan vi ställa spelen mot varandra och jämföra data. De samtliga spelen som analyseras är populära och har en aktiv spelarbas (Steam, 2017), men engagemanget på forumen skiljer sig och kan open source vara en påverkande faktor? Studien tar förutom teorin om open source upp teorier som engagemang, online community, modding och user generated content. Dessa teorier tas upp i studien för att förklara vad som engagerar användare på online forum och om open source är en bidragande faktor till ett större engagemang på steams forum. Analysdelen i studien går till på så vis att man med hjälp av en kvantitativ innehållsanalys analyserar Steams forum utifrån variabler som bestäms innan analysen utförs. Undersökningen resulterade i att det gick att se att spel som är open source har en mer engagerad community på Steams forum. Detta diskuteras vidare i analys- och diskussionsdelen utifrån den tidigare forskning och teori som presenteras teoretiska ramverket. Förutom engagemang så diskuteras även modding betydelse för användarna och exploatering utifrån ett företagsperspektiv. / In this paper, the focus will be on Steam’s forum where four games will be compared to each other. The main difference between the games is that, two of the game is open source and the two other are not. Open source means that it’s possible to modify the game from a person's own preferences with permission from the gaming company to do so. The purpose of this paper is to measure the engagement on Steam's forum by analyzing forum threads. With the help of a quantitative content analysis, the games can be compared to each other and the data as well. The games that are being studied, does all have active players (Steam, 2017), but the engagement is not the same in all gaming-communities. Can open source possibly be an influential factor to how much people engage in different forums? Besides the theory of open source, this paper includes theories about engagement, online community, modding and user generated content. These theories is included in order to explain what possibly can affect users to be more engaged in different communities, and if open source is an influential factor to greater engagement in gaming-communities. The analysis is conducted with the help of a quantitative content analysis that’s based on variables regarding Steam’s forum. The result of the analysis indicated that Steam gaming-communities based around open source games, does have more engaged users. The results are later on discussed in the analysis part, with the help of different theories and research on the subject. Aside from engagement we also discuss the meaning of modding from a user and company perspective.
