<p>This thesis goes beyond a user-centred design approach to explore potential future applications and modes of interaction. With several design cases, we investigate how early technology ideas can be matched with a specific practice to inspire novel design. This involves learning about existing experiences, interests and activities that can be relevant for a potential application, but which are not necessarily found among the intended users. Starting with early technology ideas and then finding a suitable practice to learn from is an alternative perspective of design activities. This can be useful for researchers and designers in Human Computer Interaction (HCI) who are interested in complementing approaches compared to user-centred design. Our approach is also relevant for researchers that face technology-driven starting points, and want to investigate future applications by grounding the design in existing practices.</p><p>A set of design cases show how the overall research goes from a usability-oriented perspective towards a more experience-oriented one, in order to accommodate technology-driven design situations. The design cases have involved different technical starting points, including information display technologies, surface-based networking, digital photography, and robot technology for everyday settings. The overall design process evolves towards matching the technology with a practice, and to investigate applications by developing one or more research prototypes. This has resulted knowledge of novel applications and interaction for the technology in question, as well as knowledge on how to employ empirical data to inspire novel design. Finally, we provide an overall reflection of the research process and show how a design approach that goes beyond users can benefit the design process.</p>

<p>Organizations use various resources to achieve business objectives, and for financial gain. In modern business, knowledge is a critical resource, and organizations cannot afford not to manage it. Knowledge Management (KM) aims to support learning and to create value for the organization. Based on three levels of inquiry (why, what, how), work presented in this thesis includes a synthesized view of the existing body of knowledge concerning KM and hence a holistic characterization of KM. This characterization reveals a strong dependency between KM and Learning Organization (LO). Neither of them can be successful without the other. We show that a KM project resulting in an IT-supported knowledge repository is a suitable way to start when the intention is to initiate KM work. Thus, our research focuses on ITsupported knowledge repositories.</p><p>Large numbers of KM projects fail, and organizations lack support for their KM undertakings. These are the main problems that our research addresses. In order for an IT-supported knowledge repository to be successful, it must be used. Thus, the content of the repository is critical for success. Our work reveals that the process of capturing new knowledge is critical if the knowledge repository is to include relevant and updated knowledge. With the purpose of supporting the capture process, this thesis provides a detailed characterization of the capture process as well as guidance aiming to facilitate the implementation of the capture process in such a way that knowledge is continuously captured, also after the KM implementation project is completed. We argue that the continuous capture of new knowledge which can potentially be stored in the knowledge repository will, in the long term perspective, have a positive influence on the usefulness of the repository. This will most likely increase the number of users of the repository and accordingly increase the number of successful KM projects.</p><p>All the work presented in this thesis is the result of a qualitative research process comprising a literature review and an empirical study that were carried out in parallel. The empirical study is a case study inspired by action research, which involved participation in the project Efficient Knowledge Management and Learning in Knowledge Intensive Organizations (EKLär).</p>

<p>Risk management has become recognized as a best practice in the software industry. Controlling risks improves essential software development features such as product quality, planning precision and cost-efficiency. For this reason, the inclusion of risk management in software development is an important factor to consider if one wishes to achieve project success.</p><p>Agile software development models claim to be risk-driven. They state that their iterative approach enables continuous attention to risks and that the risks can be reduced by practices such as continuous software integration and early testing. In reality, however, the agile development models implement few risk management practices.</p><p>The research problem addressed in this thesis is multi-faceted. The problem concerns the lack of explicit risk management practices in agile development. However, it also concerns the need to address risk management on an organization-wide basis. In addition, it concerns the conflict that emerges from trying to merge the agile process with standard industrial processes, such as risk management, without compromising agility.</p><p>The goal of this thesis is to explore integration as a solution for addressing the lack of risk management in the agile model based on empirical research. It involves (a) outlining a model integrating the agile and risk management processes on an organization-wide basis, and (b) providing a foundation for its extension.</p><p>The results show that, within the scope of this research, the proposed solution is a valid candidate for improving the agile situation. However, it is still in its infancy. It does not claim to be complete but needs to be further elaborated and complemented with details. Hence, we outline the model and provide a foundation established in empirical investigation for extending it in future research.</p>

<p>This Licentiate thesis is about security in automation networks with emphasis on fieldbus communication. In the process industry, network and system security have become even more important since the introduction of Ethernet-based fieldbus protocols. As an example, a successful attack on a power plant, supporting large cities with energy, could result in a temporal but total power loss. Such attacks could be devastating for the society. The security threats are real, and motivations for attacking industrial communication systems may be political or economical.</p><p>The visions of autonomous systems, which can be supervised, diagnosed and maintained from remote is not far from reality, but stress the need for security and safety measures. Wired fieldbus protocols are mature when it comes to safety and there are existing standards for safe communication. In a setup like an autonomous system security measures over safe communication has to be taken into account.</p><p>The state-of-the-art in automation security is to use firewalls to restrict incoming and outgoing traffic to the networks. Firewalls can be deployed between different automation networks, i.e. server, control, and fieldbus networks, and even protect a single automation cell with a dedicated firewall. If an adversary can penetrate the perimeter defenses, no other security countermeasures exist in process automation to protect the safety-critical communication from sabotage.</p><p>In this thesis we initially explore the possibilities of security attacks on the automation protocols PROFINET IO and PROFIsafe. We show that it is possible to attack safety-related communication to take control of safety-critical fieldbus nodes. We propose the concept of <em>Security Modules</em> in combination with PROFINET IO and PROFIsafe to achieve safe and secure real-time fieldbus communication.</p>

<p>This essay has discussed and analyzed a draft for an idea about a network called EduSync. This idea is based on that teachers and students, attending and holding courses, all over the world should be able to find and interact with each other. EduSync is founded from a new learning theory, connectivism. Interviews, participation in a conference and two workshops have been used to gather information and different points of view concerning e-learning, for example possibilities and problems with this idea of a network.  A comparison of web communities and e-learning environments that exists today was also done. The gathered information from persons as well as literature resulted in a discussion concerning learning and what would or would not be possible with the creation of EduSync. Some suggestions of future studies, both practical and scientific, are also given in this essay.</p> / <p>Den här uppsatsen har belyst och analyserat ett utkast till en nätverksidé som kallas EduSync. Denna idé grundar sig i att lärare och studenter i samtidiga liknande kurser världen över ska kunna hitta varandra och interagera. EduSync baseras på en ny lärteori, connectivism. Intervjuer och deltagande i konferenser samt workshops har använts för att samla information och olika synvinklar kring e-lärande och möjliga fördelar och nackdelar med denna nätverksidé. Det gjordes även en enklare jämförelse av idag existerande webbcommunities och lärmiljöer. Den insamlade informationen från personer och litteraturstudier resulterade i en diskussion angående lärande och vad som skulle vara möjligt eller inte att genomföra i skapandet av EduSync. Några förslag på framtida forskning, både praktisk och vetenskaplig, ges också i den här uppsatsen.</p>

<p>Many IT projects that have been developed in recent years are often considered to be unsuccessful. According to a study by Exido up to the 72% of all IT projects are considered to be failed. A failed IT projects means that the organizations that have ordered the new system may have higher costs or/and the system will not be ready in time. If costs are too high the new system might not be installed in the organization or if the system is not completed within the specified time frame the organization can become stagnant.</p><p>In this paper we conduct an investigation of the failure of IT projects there we will examine where, in the systems development lifecycle four different phases, projects fail. We will conduct an empirical study of each phase, where we describe the key steps in the process; we will also investigate failed IT projects that are linked to the current phase. After every empirical study of the phases we perform an analysis in which we describe what we believe is important to consider in the current phase, and which items have an important role in the phase that will contribute to that project fails.</p><p>We believe that the planning phase is the phase that is most important to carry out as detailed as possible when an IT project is developed. This is to ensure that the project will be successful. The phase structure of the whole project and important activities are carried out and they are affecting the other phases.</p>
