    Open Source Strategy: A Change of Perception through the Lens of Innovation: The Case of Open Source Software (OSS) in Sweden2011Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Open Source Software has been all about myths until recently, with many people believing that open source isn't reliable because the open source projects are held by a small group of amateurs in their friend's garage. Such myths have been refuted with the emerging success and increased popularity of open source, but still many considered open source and proprietary software to be enemies, which can never co-exist in the corporate platform. As a result, some firms have decided to stick to their tradition of commercial software development, while new firms, which base their corporate strategy solely on open source, have emerged. The former group of firms has suffered from losing time and money in fixing the errors and bugs in the software, whereas the latter group has found difficulties in finding financial support and market share in competition among the former group.

    Neither group has found absolute success in their business, as result a compromise model has emerged in the software industry, which resulted in a third group of firms that work neither with pure open source model nor with pure proprietary models, but instead with “hybrid” business models which allows integration of these so-called two enemies. Such firms have overcome the pitfalls of both approaches, while combining the benefits of them. The growing success of open-source integration attracted further public attention on the potential importance of open-source software (OSS). Indeed, major large commercial IT companies have started to integrate open-source software into their core strategies. Despite the widespread doubts and resistance during the early stages of open source revolution, there has recently been a “change of perception” in the software development industry towards incorporating open source strategies into their business models.

    This master thesis investigates the open source software scene in Sweden by examining Swedish firms that develop software products either based on open source components (hybrid model) or just open source products (pure open source model). After analyzing the market based on the business models of these firms, further details of the open source strategies pursued by these firms have been analyzed. Our study then finalizes the investigation with an analysis of the open source development scene in Sweden, which we use to determine the characteristics of the software industry in Sweden.

    Our conclusions reveal that open source strategy shares most of its components with innovation strategy (with some components found to be specific to open source strategy only), confirming the link between open source software and innovation. Therefore, firms that work with open source software have to pay attention to innovation and form an appropriate innovation and open source strategy if they want to be successful in the software industry.

    Performance Evaluation of Embedded Microcomputers for Avionics Applications2010Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Embedded microcomputers are used in a wide range of applications nowadays. Avionics is one of these areas and requires extra attention regarding reliability and determinism. Thus, these issues should also be born in mind in addition to performance when evaluating embedded microcomputers.

    This master thesis suggests a framework for performance evaluation of two members of the PowerPC microprocessor family, namely the MPC5554 from Freescale and PPC440EPx from AMCC, and analyzes the results within and between these processors. The framework can be generalized to be used in any microprocessor family, if required.

    Apart from performance evaluation, this thesis also suggests also a new terminology by introducing the concept of determinism levels to be able to estimate determinism issues in avionics applications more clearly, which is crucial regarding the requirements and working conditions of this very application. Such estimation does not include any practical results as in performance evaluation, but rather remains theoretical. Similar to Automark™ used by AutoBench™ in the EEMBC Benchmark Suite, we introduce a new performance metric score that we call ”Aviomark” and we carry out a detailed comparison of Aviomark with the traditional Automark™ score to be able to see how Aviomark differs from Automark™ in behavior.

    Finally, we have developed a graphical user interface (GUI) which works in parallel with the Green Hills MULTI Integrated Development Environment (IDE) in order to simplify and automate the evaluation process. By the help of the GUI, the users will be able to easily evaluate their specific PowerPC processors by starting the debugging from MULTI IDE.
