Full textThis thesis aims to support business strategic decisions of commercial FLOSS companies. This objective appears to be achieved through two specific and flexible models (theoretical study supported by set of practical proposals) and three open source companies based case studies. The five dynamics' model is used to support the definition of the strategic intents and their deployment within an open source company. Based on socio-political, psycho-cognitive and technological use dynamics, this work generates a conceptual framework integrating the concept of FLOSS environment, much broader than only communities. This model highlights the needs to identify the different actors, their roles and scopes of influence in a project, to manage their reluctance and to mobilize collaboration tools to leverage of FLOSS practices. Finally, the set of proposals can be used as guidelines for commercial FLOSS companies strategy definition and for researchers more specific studies

Full textProjetos de software livre baseados em comunidade são, geralmente, auto-organizados e dinâmicos, e recebem contribuições de voluntários espalhados por todo o globo. A sobrevivência dessas comunidades, o sucesso a longo prazo, e sua continuidade exigem a entrada constante de novatos. No entanto, os novatos enfrentam muitas barreiras ao tentarem fazer a sua primeira contribuição para um projeto de software livre, o que leva, em muitos casos, a desistências. Portanto, um grande desafio para projetos de software livre é proporcionar maneiras de apoiar os novatos durante a realização de sua primeira contribuição. Nesta tese, nosso objetivo foi identificar e compreender as barreiras que os novatos enfrentam e fornecer estratégias adequadas para reduzir essas barreiras. Para isso, realizamos diversos estudos, utilizando vários métodos de pesquisa. Para identificar as barreiras, foram utilizados dados coletados a partir de: entrevistas semiestruturadas com 36 desenvolvedores de 14 projetos diferentes; 24 respostas a um questionário aberto realizado com desenvolvedores de software livre; feedback de 9 estudantes depois de tentarem contribuir para projetos de software livre; e 20 estudos obtidos por meio de uma revisão sistemática da literatura. Os dados foram analisados utilizando-se procedimentos da Grounded Theory: codificação aberta e axial. Posteriormente, a análise resultou em um modelo conceitual preliminar composto por 58 barreiras agrupadas em seis categorias: diferenças culturais, características dos novatos, problemas de recepção, orientação dos novatos, obstáculos técnicos, e problemas de documentação. Com base no modelo conceitual, desenvolvemos o FLOSScoach, um portal para apoiar os novatos no curso de sua primeira contribuição a projetos de software livre. Para avaliar o portal, realizamos um estudo com alunos de graduação, utilizando dados qualitativos de diários, questionários de autoeficácia (self-efficacy), e o modelo de aceitação tecnológica (TAM, do inglês Technology Acceptance Model). Ao aplicar o modelo em uma aplicação prática e experimentá-lo, pudemos avaliar e melhorar o modelo de barreiras, adequando-o de acordo com as melhorias identificadas durante a concepção da ferramenta, bem como sugestões recebidas dos participantes do estudo. Os resultados do estudo indicam que o portal FLOSScoach desempenhou um papel importante no direcionamento dos novatos e na redução das barreiras relacionadas com o processo de orientação e contribuição, enquanto não foi muito eficiente na redução de barreiras técnicas. Evidenciamos ainda que o portal é útil, fácil de usar, e aumentou a confiança dos novatos. As principais contribuições desta tese são: (i) identificação empírica e modelagem de barreiras enfrentadas pelos novatos em projetos de software livre; e (ii) um portal de informação para apoiar os novatos em projetos de software livre.

Full textWhen proponents of open source software are asked to explain the success of their movement they typically point to the quality of the software produced, which is in turn attributed to the rather unconventional development model of releasing unfinished versions of the software and having users look over the code and report and fix bugs. This thesis investigates the open source quality assurance model from a knowledge management perspective based on the assumption that debugging involves a high degree of knowledge work. By doing interpretive case studies of two open source projects using direct observation, e-mail archives, and bug-trackers as data sources I present descriptive accounts of the day to day quality practices in open source development. The analysis shows that conceptualizing and classifying bugs is a complex process involving sense-making and subjective considerations; that the peer-review process in open source projects has a lot in common with traditional field-testing; and that communication tools and mediums are used interchangeably, but with certain preferences depending on subject matter. I conclude that perhaps the success of the open source development model is not due to its novelty compared to traditional software engineering, but because open source developers have recognized that debugging is a knowledge-intensive process. Keywords: Open Source, Software Quality, Knowledge Management

Full textThis thesis presents an introduction on the use of the thermal desorption technique that is based on the direct heating of the soil, for the remediation of contaminated areas. Heat propagation through soils can be mathematically simulated using coupled heat-moisture transfer theories. In order to make this simulation possible it is necessary to identify the required parameters: hydraulic conductivity as a function of volumetric water content, thermal conductivity as a function of volumetric water content, volumetric heat capacity, and soil-water characteristic curve. One technical description of such parameters is presented. Two different kinds of soils were used, one clay- sand (CH) and one sandclay (SC). A study physico-chemical was done talking into consideration the temperature effect on the soils with X-Ray, electron microscopic investigation, CTC, Atterberg Limits and at the particle size distribution. The study was done on pre-heated soils with temperatures ranging from 20 Celsius Degrees to 300 Celsius Degrees. Equipments and methodologies have been especially developed for the study of the thermo-hydraulics proprieties. The laboratory tests program consisted of hydraulic conductivity, retention curves and deformability, taking into account the temperature effects. During the tests it was observed that all parameters were temperature dependent. The thermal parameters, thermal conductivity and heat capacity were studied for both soils.

Full textThe Open Source community seems to suffer from a lack of female developers. In this thesis I have looked at different initiatives to increase the female participation. According to other studies the percentage of female open software developers is about 1.5%. My analysis of some mailing lists for open source projects shows that this number seems to be accurate. Open source is no longer a marginalised part of the IT market, but has become a mainstream and common alternative. Broader participation will probably increase the quality of the software.

Full textOpen Source Software (OSS) is becoming a real alternative to proprietary software because of the attractive characteristics it might bring (e.g. reduced costs, independence from vendors and increased innovation). Consequently, adoption of OSS is getting more attention and the industry is adopting OSS in a much larger scale than before. Telenor IS, the information system branch of Telenor Nordic, has realized that OSS adoption is increasing and noticed the advantages that OSS might bring for them. Therefore they have started a project called Open Source 2010. Among this projects goals are finding suitable OSS products to use within the company, and to increase the overall adoption of OSS to avoid lock-in to commercial vendors and be able to cut costs. As part of the Open Source 2010 project, we investigated three issues. The first is what concrete experience the individual employee has with OSS. The second is to examine the employees attitude towards OSS, and how they assess an increased use of OSS in Telenor IS. The third is exploring which advantages and risks OSS could bring, in addition to which preparations that should be made to ease the adoption of OSS. To investigate these issues, we cooperated with Telenor IS to develop a survey consisting of both interviews and a questionnaire. To validate, supplement and disseminate the results from the survey, two workshops were conducted with Telenor employees. This thesis has three main contributions. 1. Empirical findings showing that: (i) There is no real difference in attitudes towards OSS between leaders and non-leaders. (ii) A notable amount of OSS is in use, supporting that OSS adoption is increasing. (iii) Leaders are not necessarily aware of all the OSS being used. 2. Identification of several advantages, risks and preparations which are important to consider when increasing use of OSS. Several of these are generalizable, and could be considered by other companies planning to adopt OSS. 3. Increasing the visibility of the OSS project inside the Telenor IS organization. This is important, so that the individual employee in Telenor becomes aware of the project. In addition to increased visibility, the survey involves the employees and makes their voice heard in the OSS adoption process.

Industry platforms in the software sector are increasingly being developed in open source. Firms seeking to position themselves as platform leaders with such technologies must find ways of operating within the unique constraints of open source development. This thesis aims to understand those challenges by analyzing the Android and Hadoop ecosystems through an augmented version of Porter's Five Forces framework proposed by Intel's Andrew Grove. The analysis finds that platform contenders in open source behave differently depending on whether they focus on competing against alternative platforms or alternative providers of the same platform as rivals. This focus informs key decisions that the firm takes, including how it interacts with complementors and its approach to innovation. Due to the fact that open source vendors tend to lack unilateral authority over technology decisions, they can only seek to influence the behavior of the ecosystem by securing key relationships in the value network. In particular, they must secure the right engineering talent, access to key complements and superior paths to the customer. The research highlights some of the factors and tactics platform contenders in Hadoop and Android considered in acquiring these relationships. The open nature of FOSS (Free and Open Source Software) also allow new technologies to emerge and change the definition of the platform's boundaries. This creates a further strategic challenge for open source platform contenders. Keywords: platform strategy, platform leadership, open source software, Hadoop, Android.

Full textThe use of Open Source Software (OSS) has increased in both the industry and the public sector. The software intensive industry integrates OSS into their products, participates in the development of OSS products, and develops its own OSS products. The understanding of how and why the industry is approaching OSS is so far limited. To help fill this gap, this thesis intends to explore how and why the software intensive industry approaches OSS. This is done by performing an extensive literature study and by executing a web-based survey. This survey is distributed to a near representative sample of companies from the Norwegian software intensive industry and to a convenience sample of participants in the ITEA 2 research program. The research presented here shows that OSS components are widely used in the software intensive industry. Close to 50% of the Norwegian software intensive industry uses OSS in its development. The industry is mainly motivated to use OSS by practical reasons. OSS components provide functionality of high quality and the industry is satisfied with its use of these components. When using OSS, the industry benefits from the availability of source code, and easy access to components and information about these components. Companies participate in OSS projects because they use the software and because of the learning effect of this participation. The participation is however limited. However, some companies provide commercial services related to the OSS projects they participate in. Releasing a product as OSS attracts more users and customers to a product. These community members may contribute with implemented code, feedback, and requirements. There are, however some side-effects related to releasing an OSS product and companies should be aware of these consequences. The main contributions of this thesis are new understanding of how and why companies approach OSS, a reusable research design, and experiences performing survey research.

Full textWe propose a multipurpose systematic approach to extracting program facts (e. g. , function calls). This approach is supported by a suite of C and C++ program extractors, which cover different steps in the program build process and handle both source and binary code. We present several heuristics to link facts extracted from individual files into a combined system model of reasonable accuracy. We extract historical sequences of system models to aid software evolution analysis.
We propose that software evolution can be viewed as Punctuated Equilibrium (i. e. , long periods of small changes interrupted occasionally by large avalanche changes). We develop two approaches to study such dynamical behavior. One approach uses the evolution spectrograph to visualize file level changes to the implemented system structure. The other approach relies on automated software clustering techniques to recover system design changes. We discuss lessons learned from using these approaches.
We present a new perspective on software evolution dynamics. From this perspective, an evolving software system responds to external events (e. g. , new functional requirements) according to Self-Organized Criticality (SOC). The SOC dynamics is characterized by the following: (1) the probability distribution of change sizes is a power law; and (2) the time series of change exhibits long range correlations with power law behavior. We present empirical evidence that SOC occurs in open source software systems.

Full textCorporate participation in open source software touches upon a number of different issues in economics and social sciences. It is, among others, a natural experiment for the private provision of a public good, for gift giving, for collective invention, for disruptive technologies, for technology outsourcing or for decentralized organizations. Little does it surprise then that academia strives to understand corporate involvement in open source software. This thesis focuses on three aspects within this vast field: the private provision of a public good, collective invention as well as outsourcing of technology. For our analysis, we use a dataset of 10,000 open source applications from Source-Forge and relate information about developers to three categories as academic, corporate or private ones

Full textThe 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.
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.

Full textMotivations in FLOSS have always been a subject of great interest, by starting with the most obvious question, “why people work for free?”. The motivations of developers have been well established (eg von Hippel (2001), Lerner and Tirole 2002). The same exists also for big and small companies adopting FLOSS based Business Models (eg Lakhani and von Hippel, 2003; Fitzgerald 2006; Krishnamurthy, 2004). However an increasing number of SMEs with strategies not directly related to the Business Model are contributing to FLOSS communities. In this study we try to investigate these motivations under a behavioral perspective by using a research model based on TPB (Theory of Planned Behavior). We demonstrated that factors like the “openness” of a SME, the perceived importance of FLOSS, the developers (employees) of a SME along with the external environment of a SME, could influence the decision of a SME to participate in FLOSS communities. Also, we have demonstrated that some differences can be identified between high tech firms and non high tech firms. These findings can help national or regional governments to design better policies in order to better promote the use and the participation of firms to FLOSS communities. Especially now, in times of heavy economical crisis in Europe, FLOSS can be an adequate solution to foster innovation.

Full textntecedentes: el software de código abierto (OSS, por sus siglas en inglés) y los ecosistemas de software (SECOs, por sus siglas en inglés) son dos áreas de investigación consolidadas en ingeniería de software. La adopción de OSS por parte de empresas, gobiernos, investigadores y profesionales se ha incrementado rápidamente en las últimas décadas, y, en consecuencia, todos ellos hacen parte de un nuevo tipo de ecosistema formado por comunidades de software, fundaciones, desarrolladores y socios denominado ecosistema de software de código abierto. (OSSECO, por sus siglas en inglés)). Para realizar una evaluación sistemática de la calidad de un SECO, es necesario definir ciertos tipos de elementos concretos. Esto significa que tanto las métricas como las evaluaciones deben ser descritos (por ejemplo, a través de datos históricos o el conocimiento de expertos). La evaluación de la calidad de un OSSECO puede ser de utilidad desde diferentes perspectivas, por ejemplo: los que adoptan los productos del OSSECO pueden querer conocer la vitalidad del OSSECO (por ejemplo, el número de actualizaciones recientes); los desarrolladores de software pueden querer saber sobre la actividad del OSSECO (por ejemplo, cuántos colaboradores están involucrados y qué tan activos son); incluso la propia comunidad del OSSECO para conocer el estado de salud del OSSECO (por ejemplo, si está evolucionando en la dirección correcta). Sin embargo, los enfoques actuales para evaluar la calidad del software (incluso aquellos específicos para el software de código abierto) no cubren todos los aspectos relevantes en un OSSECO desde una perspectiva ecosistémica. Objetivo: El objetivo principal de esta tesis doctoral es apoyar la evaluación de la calidad de OSSECO mediante el diseño de un marco de trabajo que ayude a la evaluación de la calidad de un OSSECO. Métodos: Para lograr este objetivo, hemos utilizado un enfoque basado en la metodología design science propuesta por Wieringa [1]. Adicionalmente, nos hemos basado en la caracterización de la ingeniería de software propuesta por M. Shaw [2], con el fin de construir un conjunto de artefactos que contribuyan en la evaluación de la calidad de un OSSECO y para conocer los efectos del uso de estos artefactos en la práctica. Resultados: Hemos realizado un mapeo sistemático para caracterizar los OSSECOs y hemos diseñado el marco de trabajo denominado QuESo (es un marco de trabajo para evaluar la calidad de los OSSECOs). QuESo a su vez está compuesto por tres artefactos: (i) QuESo-model, un modelo de calidad para OSSECOs; (ii) QuESo-process, un proceso para llevar a cabo las evaluaciones de calidad de OSSECOs utilizando el modelo QuESo; y (iii) QuESo-tool, un conjunto de componentes de software que apoyan la evaluación de calidad de los OSSECOs de manera semiautomática. QuESo ha sido validado con un estudio de caso sobre Eclipse. Conclusiones: esta tesis ha contribuido a aumentar el conocimiento y la comprensión de los OSSECOs, y tambien ha apoyado la evaluación de la calidad de los OSSECOs
