For companies that develop and operate IT applications that process the personal data of customers and employees, a major problem is protecting these data and preventing privacy breaches. Failure to adequately address this problem can result in considerable damage to the company's reputation and finances, as well as negative effects for customers or employees (data subjects). To address this problem, we propose a methodology that systematically considers privacy issues by using a step-by-step privacy impact assessment (PIA). Existing PIA approaches cannot be applied easily because they are improperly structured or imprecise and lengthy. We argue that companies that employ our PIA can achieve "privacy-by-design", which is widely heralded by data protection authorities. In fact, the German Federal Office for Information Security (BSI) ratified the approach we present in this article for the technical field of RFID and published it as a guideline in November 2011. The contribution of the artefacts we created is twofold: First, we provide a formal problem representation structure for the analysis of privacy requirements. Second, we reduce the complexity of the privacy regulation landscape for practitioners who need to make privacy management decisions for their IT applications.

Abstract Product development (PD) has an important role as a key competitive factor in business environments. The capacity of designers and other stakeholders to perceive and process product related information is burdened by the increasing complexity of products and the high demands of working life. Therefore, companies need new human-centred perspectives and methods of balancing and enhancing their overall PD processes in order to develop successful products. The main motive for this research arises from the fact that ergonomics design research has been scarce from the process-oriented and systemic methods perspective. It has mainly focused on the methods, such as those needed in user interface design, and the usability and safety testing of products. The purpose of this dissertation is to consider the PD work system from the macroergonomics perspective. Macroergonomics is a top-down sociotechnical systems approach that is concerned with the analysis, design and evaluation of work systems. Nowadays, the individual user context is the dominating source of product requirements, but the designers’ work system has significant influence on its outcome as well. As an open work system, PD covers the use and design contexts of a product, not only at the individual, but also at the social and system levels. In this dissertation, the use and design contexts of products are examined through six individual studies, which were carried out during a demanding PD project of a new simulation game. In this design process, from the initial state to the goal state, macroergonomics was used as the main theoretical guideline. In many companies, PD processes are considered and developed mainly from the project management or technological points of view. However, because of the increasing complexity and systemic nature of products, PD organisations, too, will have to become more participatory, more networked and more systems oriented. As the main findings, this dissertation indicates that the macroergonomic approach can enrich the PD process and its outcomes by emphasising the balance between the technical and social subsystems of PD work system. The emerging complexity of products must be controlled from the entire PD work system, not the individual context of use only. The research introduces a new PD work system model that includes both the design and use contexts of products and demonstrates their analogical sociotechnical structures. The value of this dissertation for the industry is that companies can overcome certain emerging challenges of PD by applying the introduced macroergonomic principles. The findings of the research may encompass the re-designing of the current PD process in a company. Instead of shutting their eyes to the complexity of the surrounding world, companies should consider it as the macroergonomic PD work system and be more aware about the overall product requirements.

I denna studie undersöks effekten av spelifiering på människors träningsmotivation i förhållande till om de spelar dator-, tv- eller mobilspel regelbundet eller inte. Undersökningen genomfördes med hjälp av två testgrupper baserade på testpersonernas spelvanor. Dessa två grupper fick under tio dagar testa en egenutvecklad träningsapplikationsprototyp med fokus på spelifieringselement. Prototypens utformning framställdes med hjälp av forskningsstrategin Design Science och var baserad på tidigare forskning och teorier inom området. Målet med studien var att undersöka om det fanns någon skillnad i motivationsnivå mellan de två testgrupperna och om det fanns spelifieringselement som upplevdes som särskilt motiverande för testpersonerna. Undersökningens resultat visade att det fanns en viss skillnad mellan de två testgrupperna, där människor som spelade regelbundet upplevde prototypens spelifieringselement som mer motiverande än de som inte spelade regelbundet. Skillnaden var dock inte stor nog för att enligt oss dra några större slutsatser utifrån. De element som upplevdes som mest positiva skilde sig mellan testgrupperna. Det som ansågs motivera mest var nivåer för spelare och topplistan för icke-spelare

Clinical intelligence about a patient's risk of future adverse health events can support clinical decision making in personalized and preventive care. Healthcare predictive analytics using electronic health records offers a promising direction to address the challenging tasks of risk profiling. Patients with chronic diseases often face risks of not just one, but an array of adverse health events. However, existing risk models typically focus on one specific event and do not predict multiple outcomes. To attain enhanced risk profiling, we adopt the design science paradigm and propose a principled approach called Bayesian multitask learning (BMTL). Considering the model development for an event as a single task, our BMTL approach is to coordinate a set of baseline models-one for each event-and communicate training information across the models. The BMTL approach allows healthcare providers to achieve multifaceted risk profiling and model an arbitrary number of events simultaneously. Our experimental evaluations demonstrate that the BMTL approach attains an improved predictive performance when compared with the alternatives that model multiple events separately. We also find that, in most cases, the BMTL approach significantly outperforms existing multitask learning techniques. More importantly, our analysis shows that the BMTL approach can create significant potential impacts on clinical practice in reducing the failures and delays in preventive interventions. We discuss several implications of this study for health IT, big data and predictive analytics, and design science research.

Large software organizations handle many customer support issues every day in the form of bug reports, feature requests, and general misunderstandings as submitted by customers. Strategies to gather, analyze, and negotiate requirements are comple- mented by efforts to manage customer input after products have been deployed. For the latter, support tickets are key in allowing customers to submit their issues, bug re- ports, and feature requests. Whenever insufficient attention is given to support issues, there is a chance customers will escalate their issues, and escalation to management is time-consuming and expensive, especially for large organizations managing hundreds of customers and thousands of support tickets. This thesis provides a step towards simplifying the job for support analysts and managers, particularly in predicting the risk of escalating support tickets. In a field study at our large industrial partner, IBM, a design science methodology was employed to characterize the support process and data available to IBM analysts in managing escalations. Through iterative cycles of design and evaluation, support analysts’ expert knowledge about their customers was translated into features of a support ticket model to be implemented into a Ma- chine Learning model to predict support ticket escalations. The Machine Learning model was trained and evaluated on over 2.5 million support tickets and 10,000 escalations, obtaining a recall of 79.9% and an 80.8% reduction in the workload for support analysts looking to identify support tickets at risk of escalation. Further on- site evaluations were conducted through a tool developed to implement the Machine Learning techniques in industry, deployed during weekly support-ticket-management meetings. The features developed in the Support Ticket Model are designed to serve as a starting place for organizations interested in implementing the model to predict support ticket escalations, and for future researchers to build on to advance research in Escalation Prediction. / Graduate

E-government services in the form of information systems (IS) artifacts create a new arena for co-creation that governments aim to leverage. Design of and knowledge about IS artifacts in value co-creation in e-government can thereby be considered valuable for the future development of e-government. How IS artifacts are used in value co-creation and co-destruction and how the artifacts are developed is however not well understood. This thesis addresses the problem of how to design for and understand value co-creation in e-government. To address the problem stated, three research questions are posed. (i) How can IS artifacts be designed to enable value co-creation in e-government and what aspects can inhibit value being co-created through the designed artifacts? (ii) How can boundary object theory facilitate the understanding of IS artifacts used in value co-creation and co-destruction in e-government? (iii) How can retrospectives in design science contribute to research on value co-creation in e-government? Two artifacts in the form of instantiations are designed and evaluated. Design science research methodology is used in two different projects at Swedish municipalities. Secondary analysis is used to identify aspects that inhibit value being co-created through the designed IS artifacts. From these inhibitors, core aspects for public value co-creation are derived. Thereafter, this thesis delves further into how IS artifacts are used in collaborations between citizens, private businesses, and government agencies in order to co-create value. Two case studies are carried out at Swedish government agencies and sociomaterial boundary object theory is used to enhance understanding. The thesis research process ends with a retrospective evaluation of the performed research, using critical realism as its philosophical foundation and guidance. The result includes one configurable process model that enables value co-creation by facilitating shared understanding between collaborating parties; one mobile service that enables value co-creation through citizen sourcing; aspects that inhibit the realization of co-created value; and four core aspects that need to be considered when designing artifacts for value co-creation. That IS artifacts can be regarded as boundary objects when you aim to study and understand value co-creation and co-destruction between communities in e-government. Descriptions of how IS artifacts, viewed as sociomaterial boundary objects, are used in value co-creation processes between governments, citizens, and businesses and outcomes in terms of value co-creation and co-destruction. The benefit of performing critical realism-guided retrospectives in design science in order to complement prescriptive knowledge with explanatory and critical knowledge is motivated. It is showed that the design of artifacts generates knowledge through the design efforts, regardless of whether they also yield utility. This thesis contributes to e-government research and practice with knowledge on how to design artifacts that enable value co-creation. Establishes sociomaterial boundary object theory as a theoretical lens that offers a tool to evaluate and design IS artifacts that enable value co-creation and with knowledge on how IS artifacts are used in value co-creation. The thesis also motivates the usefulness of retrospective evaluation in design science. Suggestions for future research include further developing design science retrospectives. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 6: Manuscript.</p>

Collaboration between Designers and Scientists in the Context of Scientific Research This thesis presents the results of a research project that examines collaboration between product designers and scientific researchers. For this purpose, it initially illustrates the objectives and scope of the research and examines current relevant literature on the subject, highlighting its reach and limitations. The core research question is then introduced: How can product designers and scientists collaborate and, as a result, how might designers contribute towards scientific research activity? This question is subsequently answered in several stages. First, the relevant literature is reviewed in order to produce an analytical framework. It examines the disciplinary characteristics of designers and scientists, the characteristics of both design work and scientific research, and the nature of interdisciplinary collaboration. This analytical framework is then used as the basis for a collaboration matrix to record and examine the collaboration between designers and scientists. Secondly, the analytical framework is also employed to help explore findings from five case studies (three exploratory and two development cases) in which designers worked alongside scientists. Finally, results from the case studies are compared with current theoretical work on the subject, highlighting differences and commonalities. As a result of this analysis, the thesis answers the research question posed and presents as a main contribution: -The main ways in which designers collaborate with scientists. -The roles that designers might have while collaborating with scientists. -The contribution that designers can offer to scientific research. -The barriers to and enablers of collaboration between designers and scientists. -The areas of scientific research in which design intervention can make an impact.

La gestion interorganisationnelle des connaissances est une préoccupation croissante des organisations et, en particulier, de celles oeuvrant pour la dissuasion nucléaire française. Elle contribue à la maîtrise des connaissances nécessaires à la réussite d'un projet sur lequel plusieurs entreprises collaborent. Conduite à la Direction des applications militaires du Commissariat à l'énergie atomique, notre thèse s'intéresse au processus selon lequel une organisation cliente peut participer à la façon dont un fournisseur crée, conserve, transfert et applique les connaissances relatives aux prestations qu'elle lui achète. En ciblant la relation client / fournisseur stratégique, la recherche aborde un aspect peu exploré de la gestion interorganisationnelle des connaissances : le contrôle de la gestion des connaissances d'un fournisseur stratégique. Retenant, comme définition, que le contrôle de la gestion des connaissances d'un fournisseur stratégique est l'influence qu'un client peut exercer sur la façon dont il gère ses connaissances, la recherche démontre qu'il permet à un client de participer à la gestion des connaissances d'un fournisseur stratégique. A partir d'une approche ingénierique, notre thèse appréhende cet objet de recherche en s'appuyant sur la conception d'un guide méthodologique, proposant une démarche dédiée. Les résultats de la recherche aboutissent à la conception d'une démarche constituée de quatre étapes successives. Sa mise en oeuvre pourrait, si elle était engagée, aider un client à contrôler la gestion des connaissances d'un fournisseur stratégique et, in fine, permettre la maîtrise des connaissances relatives aux prestations qu'il lui livre. / Interorganizational knowledge management is a growing concern for organizations and, in particular, for those which belong to the French nuclear deterrence. It contributes to the mastery of knowledges required for the success of a project implying several companies. Carried out in the military applications Division of the French atomic energy Commission, our PhD thesis looks at the process allowing a client organization to participate to the way a supplier acquire, conserve, transfer and apply knowledges relevant to the deliveries that it purchased. Focusing on the client / strategic supplier relationship, the research addresses an unexplored aspect of interorganizational knowledge management: the knowledge management control of a strategic supplier. Since knowledge management control of a strategic supplier can be defined as the influence that a customer may have on how a strategic supplier manages its knowledge, research demonstrates that it allows the client to participate in knowledge management deployed by the strategic supplier. From a design science approach, our PhD thesis deals with this research object owing to the design of a methodological guide which proposes a dedicated process. The results of the research lead to the design of a process which consists in four stages. If it was in use, the process implementation could help a customer to control knowledge management of a strategic supplier and, finally, enable the mastery of knowledges related to the purchased deliveries.

Die Integration von Produkten und Dienstleistungen zu einem nutzenstiftenden Leistungsbündel und das damit einhergehende ökonomische und ökologische Potenzial ist auch heute noch mittel- bzw. unmittelbarer Gegenstand vielfältiger Untersuchungen in Wissenschaft und Praxis. Als Konzept hat die Hybride Wertschöpfung viele Merkmale wie die Interdisziplinarität bei der Leistungserstellung, die Substituierbarkeit von Bestandteilen oder die Ausrichtung am gesamten Lebenszyklus geprägt, welche auch in vielen anderen Konzepten Anwendung finden. Trotzdem hat sie als etablierte Betrachtungsweise bislang keine umfassende Erweiterung erfahren, mit der sie beispielsweise die seit vielen Jahren vorherrschende Digitalisierung von Produkten und Dienstleistungen durch Informations- und Kommunikationstechnologie nutzen und integrieren kann. Stattdessen entstehen neue, analoge und teilweise konkurrierende Konzepte, welche die Bildung eines theoretischen Kerns hemmen. Die vorliegende Dissertation adressiert diese Fragestellung und entwickelt einen Ansatz, mit dem die informationsbasierte Integration von Produkten und Dienstleistungen und damit die Nutzung der Digitalisierungspotenziale gelingen kann. Damit folgt die Arbeit dem anwendungs- und schnittstellenorientierten Anspruch der Wirtschaftsinformatik und generiert Ergebnisse in den folgenden Bereichen: (1) Identifikation von Anforderungen an die Entwicklung informationsbasierte hybrider Leistungsbündel, (2) konzeptuelle Zusammenführung der unterschiedlichen Komponenten Produkt und Dienstleistung sowie (3) die prototypische Implementierung einer Plattformlösung zur Unterstützung der Entwicklung entsprechender Leistungsbündel. Die Arbeit leistet somit einen wesentlichen Beitrag zur systemischen Weiterentwicklung des Hybriden Wertschöpfungskonzepts, um als etabliertes Rahmenwerk weiterhin Bestand zu haben und für die Erklärung und Entwicklung neuer Leistungsportfolios verwendbar zu sein.
