  • Understanding the requirements for developing Open Source Software systems
    IEE Proceedings - Software, 2002
    Co-Authors: Walt Scacchi
    Abstract:

    Presents an initial set of findings from an empirical study of social processes, technical system configurations, organisational contexts and interrelationships that give rise to Open Software. The focus is directed at understanding the requirements for Open Software development efforts, and how the development of these requirements differs from those traditional to Software engineering and requirements engineering. Four Open Software development communities are described, examined and compared to help discover what these differences may be. Eight kinds of Software informalisms are found to play a critical role in the elicitation, analysis, specification, validation and management of requirements for developing Open Software systems. Subsequently, understanding the roles these Software informalisms take in a new formulation of the requirements development process for Open Source Software is the focus of the study. This focus enables the consideration of a reformulation of the requirements engineering process and its associated artefacts, or (in)formalisms, to better account for the requirements for developing Open Source Software systems

  • code reuse in Open Source Software
    Management Science, 2008
    Co-Authors: Stefan Haefliger, Georg Von Krogh, Sebastian Spaeth
    Abstract:

    Code reuse is a form of knowledge reuse in Software development that is fundamental to innovation in many fields. However, to date there has been no systematic investigation of code reuse in Open Source Software projects. This study uses quantitative and qualitative data gathered from a sample of six Open Source Software projects to explore two sets of research questions derived from the literature on Software reuse in firms and Open Source Software development. We find that code reuse is extensive across the sample and that Open Source Software developers, much like developers in firms, apply tools that lower their search costs for knowledge and code, assess the quality of Software components, and have incentives to reuse code. Open Source Software developers reuse code because they want to integrate functionality quickly, because they want to write preferred code, because they operate under limited reSources in terms of time and skills, and because they can mitigate development costs through code reuse.

  • knowledge reuse in Open Source Software an exploratory study of 15 Open Source projects
    Hawaii International Conference on System Sciences, 2005
    Co-Authors: Georg Von Krogh, Sebastian Spaeth, Stefan Haefliger
    Abstract:

    To date, there is no investigation of knowledge reuse in Open Source Software projects. This paper focuses on the forms of knowledge reuse and the factors impacting on them. It develops a theory drawn from data of 15 Open Source Software projects and finds that the effort to search, integrate and maintain external knowledge influences the form of knowledge to be reused. Implications for firms and innovation research are discussed.

  • The transformation of Open Source Software
    MIS Quarterly: Management Information Systems, 2006
    Co-Authors: Brian Fitzgerald
    Abstract:

    A frequent characterization of Open Source Software is the somewhat outdated, mythical one of a collective of supremely talented Software hackers freely volunteering their services to produce uniformly high-quality Software. I contend that the Open Source Software phenomenon has metamorphosed into a more mainstream and commercially viable form, which I label as OSS 2.0. I illustrate this transformation using a framework of process and product factors, and discuss how the bazaar metaphor, which up to now has been associated with the Open Source development process, has actually shifted to become a metaphor better suited to the OSS 2.0 product delivery and support process. Overall the OSS 2.0 phenomenon is significantly different from its free Software antecedent. Its emergence accentuates the fundamental alteration of the basic ground rules in the Software landscape, signifying the end of the proprietary-driven model that has prevailed for the past 20 years or so. Thus, a clear understanding of the characteristics of the emergent OSS 2.0 phenomenon is required to address key challenges for research and practice.

  • perspectives on free and Open Source Software
    Perspectives on Free and Open Source Software, 2005
    Co-Authors: Joseph Feller, Scott A Hissam, Brian Fitzgerald, Karim R. Lakhani
    Abstract:

    What is the status of the Free and Open Source Software (F/OSS) revolution? Has the creation of Software that can be freely used, modified, and redistributed transformed industry and society, as some predicted, or is this transformation still a work in progress? Perspectives on Free and Open Source Software brings together leading analysts and researchers to address this question, examining specific aspects of F/OSS in a way that is both scientifically rigorous and highly relevant to real-life managerial and technical concerns. The book analyzes a number of key topics: the motivation behind F/OSS—why highly skilled Software developers devote large amounts of time to the creation of "free" products and services; the objective, empirically grounded evaluation of Software—necessary to counter what one chapter author calls the "steamroller" of F/OSS hype; the Software engineering processes and tools used in specific projects, including Apache, GNOME, and Mozilla; the economic and business models that reflect the changing relationships between users and firms, technical communities and firms, and between competitors; and legal, cultural, and social issues, including one contribution that suggests parallels between "Open code" and "Open society" and another that points to the need for understanding the movement's social causes and consequences.

  • developing Open Source Software a community based analysis of research
    Social Inclusion, 2006
    Co-Authors: Joseph Feller, Patrick Finnegan, David Kelly, Maurice Macnamara
    Abstract:

    Open Source Software (OSS) creates the potential for the inclusion of large and diverse communities in every aspect of the Software development and consumption life cycle. However, despite 6 years of effort by an ever growing research community, we still don’t know exactly what we do and don’t know about OSS, nor do we have a clear idea about the basis for our knowledge. This paper presents an analysis of 155 research artefacts in the area of Open Source Software. The purpose of the study is to identify the kinds of Open Source project communities that have been researched, the kinds of research questions that have been asked, and the methodologies used by researchers. Emerging from the study is a clearer understanding of what we do and don’t know about Open Source Software, and recommendations for future research efforts
