    Television on the Internet: New Practices, New Viewers2009Inngår i: International Conference on Human Factors in Computing Systems, ACM , 2009Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Television is increasingly viewed through computers in the form of downloaded or steamed content, yet computer based television consumption has received little attention in HCI. In this paper we describe a study of the uses and practices of tech-savvy college students, studying their television consumption through the internet. We find that users personalize their viewing but that TV is still a richly social experience - not as communal watching, but instead through communication around television programs. We explore new possibilities for technology-based interaction around television.

    The Mismeasurement of Privacy: Using Contextual Integrity to Reconsider Privacy in HCI2012Inngår i: CHI '12: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, New York: Association for Computing Machinery (ACM), 2012, s. 367-376Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Privacy is a widely studied concept in relation to social computing and sensor-based technologies; scores of research papers have investigated people’s ‘privacy preferences’ and apparent reluctance to share personal data. In this paper we explore how Ubicomp and HCI studies have approached the notion of privacy, often as a quantifiable concept. Leaning on several theoretical frameworks, but in particular Nissenbaum’s notion of contextual integrity, we question the viability of obtaining universal answers in terms of people’s ‘general’ privacy practices and apply elements of Nissenbaum’s theory to our own data in order to illustrate its relevance. We then suggest restructuring inquiries into information sharing in studies of state-of-the-art technologies and analyze contextually grounded issues using a different, more specific vocabulary. Finally, we provide the first building blocks to such vocabulary.

    The Sociality of Fieldwork: Designing for Social Science Research Practice and Collaboration2012Inngår i: PROCEEDINGS OF THE 17TH ACM INTERNATIONAL CONFERENCE ON SUPPORTING GROUP WORK, Association for Computing Machinery (ACM), 2012, s. 35-44Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Supporting scientific practice has been a longstanding goal of CSCW research. This paper explores how we might design for social science research practices and collaboration. Drawing on sixteen interviews with fieldwork-based social scientists we document the importance of small-scale long-term collaborative arrangements for research and intellectual work - pairs of researchers who work together in-depth over their careers, developing a common yet distinctive view of their research field. This contrasts with the large-scale short-lived collaborations that have classically been the target of cyber-infrastructure work. We describe technology practices among social scientists and how these can inform technology design for fieldwork practices.

    Unpacking the television: User practices around a changing technology2009Inngår i: Transactions n Computer-Human Interaction, Vol. 16Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article investigates the changing television watching practices amongst early adopters of personal hard-disk video recorders (such as Tivo) and Internet downloading of video. Through in- depth interviews with 21 video enthusiasts, we describe how the rhythms of television watching change when decoupled from broadcast TV schedules. Devices such as Tivo do not simply replace videotapes; TV watching becomes more active as programs are gathered from the schedules, played from a stored collection and fast forwarded and paused during playback. Downloads users exploit the Internet to view shows and movies not broadcast, yet this watching is not fundamentally different from recording shows using a PVR, since both involve selection of shows from a limited range and a wait before the shows can be watched.

    Engaging the Periphery for Visual Communication on Mobile Phones2010Inngår i: Hawaii International Conference on System Sciences, IEEE , 2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    While mobile phones have become ubiquitous instruments of communication and social interaction, they still require explicit interaction, placing high demands on attention. Engaging the periphery of users’ attention offers opportunities for awareness and interaction while reducing demands on attention and risks of disruption. We explore the mobile peripheral design space with Emotipix, an application for camera phones that turns the background of the phone’s display into a place for visual conversations. We conducted an exploratory 2-week user study with 6 pairs and one 4- person group, and found that Emotipix facilitated ongoing social practices. Our study shows that there is an unexploited opportunity to use mobile phones for peripheral awareness. We provide recommendations for managing users’ expectations, desires for control, and privacy in mobile peripheral display design.

    Watching the footwork: second screen interaction at a dance and music performance2014Inngår i: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, New York: Association for Computing Machinery (ACM), 2014, s. 1305-1314Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Interactive mobile technologies have become part of audience experiences of live performances in terms of both general media sharing and specific (sometimes official) extra content. At the same time, high bandwidth affords streaming of live events to mobile devices. We take advantage of these technologies in our high resolution, panoramic image video stream and study a scenario of audience members viewing the very same live event they are watching on a tablet. The video stream on the tablet is navigational and enables audience members to pan and zoom in the real-time video feed. We studied audience interaction and impressions in three performances of a dance and music show and found distinct uses of the second screen video stream. We emphasize that despite initial reluctance, the observed utilization of the technology opened up for new potential practices. Our study shows how working with perceived conflict in technology can still open up design space for interactive technologies.

    Abstract [en]

    In this work-in-progress we explore audience behavior at large musical events and present our prototype, a ‘cheering meter’ developed to aid voting at rap competitions. We report from use of the cheering meter at eight concerts and conclude by highlighting how augmented interaction can increase the sense of participation among the audience at large-scale performances.

    Acting with Technology: Rehearsing for Mixed-Media Live Performances2016Inngår i: CHI '16 Proceedings of the 2016 CHI Conference on Human Factors in Computing Systems, Association for Computing Machinery (ACM), 2016, s. 864-875Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Digital technologies provide theater with new possibilities for combining traditional stage-based performances with interactive artifacts, for streaming remote parallel performances and for other device facilitated audience interaction. Compared to traditional theater, mixed-media performances require a different type of engagement from the actors and rehearsing is challenging, as it can be impossible to rehearse with all the functional technology and interaction. Here, we report experiences from a case study of two mixed-media performances; we studied the rehearsal practices of two actors who were performing in two different plays. We describe how the actors practiced presence during rehearsal in a play where they would be geographically remote, and we describe the challenges of rehearsing with several remote and interactive elements. Our study informs the broader aims of interactive and mixed media performances through addressing critical factors of implementing technology into rehearsal practices.

    Interactive Performances as a Means of Social Participation and Democratic Dialogue2014Inngår i: International Reports on Socio-Informatics (IRSI), ISSN 1861-4280, E-ISSN 1861-4280, Vol. 11, nr 1, s. 11-20Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this position paper we present our ongoing research in relation to cultivating democracy and civic participation through the writing and performance of interactive theater experiences1. We provide an example of a performance that facilitates audience participation through expression and sharing of opinions and emotions, by means of digital technologies. The performance leads to further discussion within the community and inspires more artistic and theatrical experiences in this context.

    Social networking on the go: Students' socialization in the age of Facebook2010Inngår i: International conference on Human factors in computing systems (CHI), ACM , 2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Most research regarding online social networks such as Facebook, MySpace, Linked-In and Friendster has looked at these networks in terms of activity within the online network, such as profile management and friending behavior. In this paper we are instead focusing on offline socializing structures around an online social network (exemplified by Facebook) and how this can facilitate in- person social life for students. Because students lead nomadic lives, they find Facebook a particularly useful tool for initiating and managing social gatherings, and as they adopt mobile technologies that can access online social networks, their ad-hoc social life is further enabled. We conclude that online social networks are a powerful tool for encouraging peripheral friendships, important in particular to students. We emphasize that the use of online social networks must be viewed from a perspective of use that involves both mobile and stationary platforms and that it is important to relate online and offline social practices.

    New interaction modes for rich panoramic live video experiences2014Inngår i: Behavior and Information Technology, ISSN 0144-929X, E-ISSN 1362-3001, Vol. 33, nr 8, s. 859-869Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The possibilities of panoramic video are based on the capabilities of high-resolution digital video streams and higher bandwidth's opportunities to broadcast, stream and transfer large content across platforms. With these opportunities also come challenges such as how to focus on sub-parts of the video stream and interact with the content shown on a large screen. In this paper, we present studies of two different interaction modes with a large-scale panoramic video for live experiences; we focus on interactional challenges and explore if it is (1) possible to develop new interactional methods/ways of approaching this type of high-resolution content and (2) feasible for users to interact with the content in these new ways. We developed prototypes for two different interaction modes: an individual system on a mobile device, either a tablet or a mobile phone, for interacting with the content on the same and a non-touch gesture-based system for the home or small group interaction. We present pilot studies where we explore the possibilities and challenges with these two interaction modes for panoramic content.

    Impediments to Effective Management of Project Interdependencies: A Study of IT/IS Project Portfolios2017Inngår i: Journal of Electronic Commerce in Organizations, ISSN 1539-2937, E-ISSN 1539-2929, Vol. 15, nr 2, s. 16-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Interdependencies between projects have come to play a more active role in the decision on IT/IS portfolios and their constituent projects. However, managing these interdependencies can be a complex task, especially when the number and degree of interdependencies among projects are high. In times of uncertainty, unexpected challenges can seriously disrupt projects and, consequently, their interdependencies. This may threaten the project portfolio from achieving its final goal. The study aims to investigate the difficulties associated with managing project interdependence along the development cycle of the project portfolio. The study was conducted using a qualitative approach and semi-structured interviews with managers from four leading organizations in Saudi Arabia. The findings reveal three main categories of factors that increased the difficulty of managing project interdependencies in large IT/IS project portfolios: insufficient understanding of human responsibilities in the whole portfolio, unpredictability of the environment, and technology barriers and constraints.

    INVESTIGATING THE SOURCES OF DIFFICULTIES IN MANAGING PROJECT INTERDEPENDENCIES: A STUDY OF IT/IS PROJECT PORTFOLIOS2016Inngår i: PROCEEDINGS OF THE 9th IADIS INTERNATIONAL CONFERENCE INFORMATION SYSTEMS 2016 / [ed] Miguel Baptista Nunes, Pedro Isaías, Philip Powell, IADIS Press, 2016, s. 71-82Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Interdependencies between projects can take a major role in IT/IS project portfolios. However, managing these interdependencies can be a difficult task, especially when the number and diversity of projects grow large in scale. In times of unexpected events, extra management efforts are inevitable for treating the subsequent effects on the projects and their interdependencies, and for maintaining high-performance portfolios. Complexity is also a concern for managers, and a growing complexity level may threatens the project portfolio from achieving its final goal. This paper investigates the managerial issues and difficulties in handling project interdependencies. For a closer look at these interdependencies and to gain more understanding of the problem area, a qualitative study was conducted based on semi-structured interviews with managers from four leading organizations in different industries in Saudi Arabia. The findings reveal three main sources of difficulty in managing project interdependencies in IT/IS project portfolios: 1) Insufficient understanding of human responsibilities in the whole portfolio, 2) Environmental change and 3) Technological constraints.

    Managing project interdependencies in IT/IS project portfolios: a review of managerial issues2016Inngår i: International journal of information systems and project management, ISSN 2182-7796, E-ISSN 2182-7788, Vol. 4, nr 1, s. 67-82Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Adequately managing project interdependencies among diverse and simultaneous projects is deemed critical for successful implementation of project portfolios. The challenge is significant because it may entail managing a complex network of project interdependencies that keeps changing over time. The present study investigates the managerial challenges that may undermine effective management of project interdependencies in IT/IS project portfolios. The investigation is based on evidence from reviewing relevant literature and documented studies associated with managing project interdependencies. The main contribution of this study is to discuss three managerial challenges of project interdependencies in project portfolios. We discuss the challenges from three perspectives: types of interdependencies; patterns of interaction in interdependencies; and cost/benefit impact of project interdependencies.

    Project interdependency management in IT/IS project portfolios: from a systems perspective2016Inngår i: Procedia Computer Science, ISSN 1877-0509, E-ISSN 1877-0509, Vol. 100, s. 928-934Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Capitalizing on inter-project interdependencies is widely accepted as being crucial for Information Technology/Information Systems (IT/IS) project portfolio success. However, handling these interdependencies becomes a source of increased management complexity as project portfolios get larger, increasingly diverse, and are much influenced by their environments. This then can lead to less predictable situations regarding the portfolio performance as a whole. Though there are many methods available for optimally selecting projects and cross-checking possible synergies and interdependencies among the projects in the portfolio, it remains unclear how one can gain control over the complexity of managing these interdependencies. In this study, we address the problem of handling many project interdependencies that continuously change and develop within a large IT/IS project portfolio. We found that the existing methods for selecting and managing the projects within a portfolio do not focus enough on how interdependencies can disrupt the balance of the whole project portfolio system. To tackle the problem, we propose a systemic approach using the Viable System Model to enhance the way that these interdependencies can be effectively managed in view of the overall portfolio system. We suggest that the Viable System Model, as a supplement to traditional IT/IS project portfolio management approaches, is recursively applied to diagnose and manage the complexity of project interdependencies within IT/IS project portfolios.

    The Viable System Model for Diagnosing and Handling IT-Project Interdependencies in Large Portfolios2018Inngår i: International Journal of Information Technology Project Management, ISSN 1938-0232, E-ISSN 1938-0240, Vol. 10, nr 1, artikkel-id 5Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Adequately considering project interdependencies has shown to be a determinant of how successful IT/IS project portfolios are managed. However, this can be especially troublesome since there is no universal way to handle many project interdependencies that continue to change over time due to environmental uncertainty or unexpected decisions. This can seriously disrupt portfolio performance. In this article, the authors used the systems perspective to address the problem of managing multiple IT-project interdependencies in complex IT/IS portfolio environment. In particular, the authors propose using the cybernetic model Viable System Model to facilitate thinking and reasoning concerning the difficulty of managing IT-project interdependencies. To validate their approach and to ensure the appropriateness of it, the authors used real-world problem situations drawn from multiple case studies conducted in four leading organizations in Saudi Arabia. The findings support that the Viable System Model can be applied to assist in diagnosing and handling of IT-project interdependencies.

    A large comparison of integrated SAR/QSAR models of the Ames test for mutagenicity($)2018Inngår i: SAR and QSAR in environmental research (Print), ISSN 1062-936X, E-ISSN 1029-046X, Vol. 29, nr 8, s. 591-611Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Results from the Ames test are the first outcome considered to assess the possible mutagenicity of substances. Many QSAR models and structural alerts are available to predict this endpoint. From a regulatory point of view, the recommendation from international authorities is to consider the predictions of more than one model and to combine results in order to develop conclusions about the mutagenicity risk posed by chemicals. However, the results of those models are often conflicting, and the existing inconsistency in the predictions requires intelligent strategies to integrate them. In our study, we evaluated different strategies for combining results of models for Ames mutagenicity, starting from a set of 10 diverse individual models, each built on a dataset of around 6000 compounds. The novelty of our study is that we collected a much larger set of about 18,000 compounds and used the new data to build a family of integrated models. These integrations used probabilistic approaches, decision theory, machine learning, and voting strategies in the integration scheme. Results are discussed considering balanced or conservative perspectives, regarding the possible uses for different purposes, including screening of large collection of substances for prioritization.

    How Was Your Day? Evaluating a Conversational Companion2013Inngår i: IEEE Transactions on Affective Computing, ISSN 1949-3045, E-ISSN 1949-3045, Vol. 4, nr 3, s. 299-311Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The How Was Your Day(HWYD) companion is an embodied conversational agent that can discuss work-related issues, entering free-form dialogues while discussing issues surrounding a typical work day. The open-ended nature of these interactions requires new models of evaluation. Here, we describe a paradigm and methodology for evaluating the main aspects of such functionality in conjunction with overall system behavior, with respect to three parameters: functional ability (i.e., does it do the rightthing conversationally), content (i.e., does it respond appropriately to the semantic context), and emotional behavior (i.e., given the emotional input from the user, does it respond in an emotionally appropriate way). We demonstrate the functionality of our evaluation paradigm as a method for both grading current system performance, and targeting areas for particular performance review. We show correlation between, for example, automatic speech recognition performance and overall system performance (as is expected in systems of this type), but beyond this, we show where individual utterances or responses, indicated as positive or negative, characterize system performance, and demonstrate how our combination evaluation approach highlights issues (both positive and negative) in the companion system's interaction behavior.

    The Use of Learning Technologies and Student Engagement in Learning Activities2018Inngår i: Nordic Journal of Digital Literacy, ISSN 1891-943X, E-ISSN 1891-943X, Vol. 13, nr 2, s. 113-130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As digitalisation spreads in education, it is vital to understand its relation to student engagement. We used student diaries and observation data to approach student engagement and explore the use of learning technologies on a lesson-to-lesson basis. Results show that a less thought-through use of technologies might lead to unconsidered effects. Positive indicators of the facilitation of student engagement included making the learning process accessible and visible to teachers.

    ‘So, You Think It’s Good’ - Reasons Students Engage When Learning with Technologies – a Student Perspective2018Inngår i: EDULEARN18: Proceedings / [ed] L. Gómez Chova, A. López Martínez, I. Candel Torres, The International Academy of Technology, Education and Development, 2018, s. 9556-9563Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Student engagement is significantly related to school success. With the increasing digitalisation of education, it is essential to explore if student engagement is affected by the uptake of learning technologies (LTs). The aim of this study was to approach what factors students perceive to influence their engagement when learning with technologies. This was done by asking students to report their level of engagement and fill in a questionnaire to evaluate a classroom intervention designed to facilitate engagement. The intervention included a learner assessment application, a virtual learning environment (VLE) And a separate tablet the teacher used to access the shared workspace. These LTs facilitated instant feedback between the teacher and the students and enabled multiple simultaneous dialogues which allowed all students to engage with both content and peers. Results show that students’ invested effort in learning activities were related to their reported levels of engagement. Surprisingly, in this intervention, control and stress showed no correlation with engagement. Some aspects of peer modelling and feedback showed weak correlations, albeit these were non-significant. Instead, students reported that feeling ‘content with one’s outcomes’ and ‘engaging in learner-centred dialogues’ were their main reasons to engage. Moreover, students’ reasons to engage in short tasks were not the same as their reasons to engage with long-term goals, such as completing their assignment. The results show that conditions for learning changed when implementing LTs. As conditions for learning changed, so did students’ reasons to engage. Moreover, insights into students’ reasons to engage and reported levels of engagement to suggest that obtaining this information can be useful to identify students in at-risk zones and offer them the support needed. Orchestration of inclusive engagement and implications for future designs are discussed.

    Designing for Engagement in TEL – a Teacher-Researcher Collaboration2018Inngår i: Designs for Learning, ISSN 1654-7608, Vol. 10, nr 1, s. 100-111Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Hence, teachers need to consider how their practices affect student engagement. Applying design-based research (DBR), the purpose of this study was to approach influencers of student engagement and explore how teachers and researchers collaboratively could develop learning activities with learning technologies (LTs) to facilitate this. The intervention included an online assessment application, a virtual learning environment (VLE) and an additional tablet for the teacher. The teacher constantly carried the tablet around and used it to access the students’ shared workspace. The intervention was implemented in two classes in an upper secondary school. The study focuses on teachers’ experience and instruction. Three observations of the implementation of learning design and intervention evaluations were analysed. The results indicate that the teachers and researchers could design learning activities that facilitate student engagement. Engagement was facilitated as hindrances to engagement were identified and approached. The suggested solutions shaped the design of the learning activity and included LTs which provided insights into the students’ learning processes and thereby increased the teacher’s ability to scaffold learning and provide timely feedback. The LTs used opened up for additional ways for students to engage with the content, peers and contributions which motivated students to direct their energy toward task. When conditions for learning changed as a result of implementing LTs, both student interaction and teacher practices were affected. However, it was not observed that the teacher would sustain the design without support. This emphasises the need for educational goals and visions to be consistent and communicated to practitioners; otherwise, teachers will not have the guidance needed to advance or evaluate their professional development.

    Abstraction, Restriction, and Co-creation: Three Perspectives on Services2010Inngår i: Advances in Conceptual Modeling – Applications and Challenges, Berlin: Springer Verlag , 2010, s. 107-116Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The recent surge in the interest of services has brought a plethora of applications of the service concept. There are business services and software services, software-as-a-service, platform-as-a-service, and infrastructure-as-a-service. There is also a multitude of definitions of the service concept. In this paper, we propose not a new definition of service but a conceptual model of the service concept that views services as perspectives on the use and offering of resources. The perspectives addressed by the model are: service as a means for abstraction; service as means for providing restricted access to resources; and service as a means for co-creation of value.

    Towards a Model of Services Based on Cocreation, Abstraction and Rights Distribution2015Inngår i: Correct Software in Web Applications and Web Services / [ed] Bernhard Thalheim, Klaus-Dieter Schewe, Andreas Prinz, Bruno Buchberger, Cham: Springer, 2015, s. 29-44Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    The term service is today defined and used in a multitude of ways, which are often ambiguous and contradictory. The absence of a commonly agreed-upon definition of the term makes it difficult to distinguish, describe and classify services. In order to address these issues, this chapter proposes a model of services that helps in analysing the concept. The model encompasses three perspectives: service as a means for cocreation of value, service as a means for abstraction and service as a means for distributing rights. The model does not suggest a definition of the term service but shows how the service concept can be analysed using a number of related concepts, like service resource, service process and service offering. The model has its theoretical foundation in the Resource-Event-Agent (REA) ontology and Hohfeld’s classification of rights.

    Framework for evaluating tools used in edemocracy: transparency, autonomy, consensus and pluralism2014Inngår i: DSV Writers Hut 2014: proceedings  August 21-22, 2014, Åkersberga, Sweden, Stockholm: Stockholm University, 2014Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The concept of e-democracy has been around for a while. However, the intercontextual understanding of this is still immature which complicates interdisciplinarity and communication with a diversity of stakeholders, resulting in a weak participation and implementation of e-services. This is even more emphasized in an international setting, not the least in the context of various European Union initiatives regarding e-service provision. To increase the participation in the context, e-democracy services can be utilized for strengthening individual capabilities as well as political processes. The effective design of such processes requires tools to support decision-making, collaboration, and collaborative decision-making, voting engagement and involvement in the democratic process. This article presents an evaluation framework suitable for tools for e-democracy aiming at forming a constructive base for implementing an efficient support for enabling an increased participation in vital democratic processes.

    Towards a Sociomaterial Ontology2013Inngår i: Advanced Information Systems Engineering Workshops: CAiSE 2013 International Workshops. Proceedings / [ed] Xavier Franch, Pnina Soffer, Springer Berlin/Heidelberg, 2013, s. 341-348Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The management of social phenomena in conceptual modelling requires a novel understanding of the notion of representation. In particular, the principles for the existence and identification of objects need to be reconsidered. To do this, the paper draws on the current ontological discourse in information systems engineering and proposes a sociomaterial ontology for supporting conceptual modeling. The ontology shows how organisational entities are grounded in physical ones and how they can be understood in terms of deontic notions like privileges, duties and powers. The sociomaterial ontology is able to assist designers in creating understandable and robust conceptual models.

    A pattern and dependency based approach to the design of process models2004Konferansepaper (Annet vitenskapelig)
    Abstract [en]
    In this paper an approach for building process models for e-commerce is proposed. It is based on the assumption that the process modeling task can be methodologically supported by a designers assistant. Such a foundation provides justifications, expressible in business terms, for design decisions made in process modeling, thereby facilitating communication between systems designers and business users. Two techniques are utilized in the designers assistant, namely process patterns and action dependencies. A process pattern is a generic template for a set of interrelated activities between two agents, while an action dependency expresses a sequential relationship between two activities.

    Towards a model of services based on co-creation, abstraction and restriction2011Inngår i: International Conference on Conceptual Modeling (ER) 2011, Brussels: Springer , 2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The term service is today defined and used in a multitude of ways, and there is no usage characteristic that is common for all of these ways. As a consequence natural language terms used for describing services are ambiguous and often confusing. The lack of a common agreed upon definition of the term makes it difficult to understand and classify services as well as distinguish them from non-service concepts. In this paper, we do not propose a new definition of service but a model of services that helps in analysing the concept. The model is based on three perspectives: service as a means for co-creation of value, service as a means for abstraction, and service as a means for providing restricted access to resources.

    Abstract [en]

    Automated diagnosis coding can be provided efficiently by learning predictive models from historical data; however, discriminating between thousands of codes while allowing a variable number of codes to be assigned is extremely difficult. Here, we explore various text representations and classification models for assigning ICD-9 codes to discharge summaries in MIMIC-III. It is shown that the relative effectiveness of the investigated representations depends on the frequency of the diagnosis code under consideration and that the best performance is obtained by combining models built using different representations.

    Abstract [en]

    The need for organizations to operate in changing environments is addressed by proposing an approach that integrates organizational development with information system (IS) development taking into account changes in the application context of the solution. This is referred to as Capability Driven Development (CDD). A meta-model representing business and IS designs consisting of goals, key performance indicators, capabilities, context and capability delivery patterns, is being proposed. The use of themeta-model is validated in three industrial case studies as part of an ongoing collaboration project, whereas one case is presented in the paper. Issues related to the use of the CDD approach, namely, CDD methodology and tool support are also discussed.

    AGILE RESEARCH IN INFORMATION SYSTEMS FIELD: ANALYSIS FROM KNOWLEDGE TRANSFORMATION PERSPECTIVE2015Inngår i: Proceedings of the 8th IADIS International Conference on Information Systems 2015 / [ed] Miguel Baptista Nunes, Pedro Isaías, Philip Powell, IADIS Press, 2015, s. 3-10Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Due to the relative success of agile methods in software development, the idea of having agile processes started to be tested in other areas, for example, agile business process development. This trend already reached the research community and there have appeared some materials that suggest using agility in research projects. Analysis of these suggestions, however, shows that they do not go beyond finding superficial analogy between the concepts of the software development and research projects. The paper presents a deeper analysis of the concept of agile research in Information Systems (IS) based on the analysis of the research projects from the knowledge transformation perspective. As a basis for analysis, the SECI model of Nonaka is used. Based on this analysis, several suggestions are made on how to conduct agile research in IS, e.g. prioritize relevance over vigor, test early for a practical purpose, use own experience and reflections, etc. It is also shown that some research types, like action research and design science, are more suitable for conducting agile research than others. The paper also gives analysis of risks of non-agile research, and presents an example where they are revealed.

    Analysis of Agile Software Development from the Knowledge Transformation Perspective2014Inngår i: Perspectives in business informatics research: 13th International Conference, BIR 2014, Lund, Sweden, September 22-24, 2014. Proceedings / [ed] Björn Johansson, Berlin: Springer, 2014, s. 143-157Konferansepaper (Fagfellevurdert)
    Abstract [en]

    While the Agile Software Development (ASD) has been successfully promoted in the last 15 years, there is no agreement on how to determine whether a particular project is agile or not. Some practitioners consider agility as strict usage of a specific methodology, e.g. SCRUM, others consider agility as adhering to Agile Manifesto. The lack of common view on ASD prevents creating common guidelines on when the usage of ASD is appropriate. This paper presents a model of ASD that helps to differentiate it from the traditional, phase-based development, and more strictly defines the area of its applicability. The model has been built based on the knowledge transformation perspective, as the author considers it to be the most differentiating perspective when comparing ASD to traditional software development. For building the model, the ideas from SECI model of Nonaka have been exploited. The results, in the form of requirements to be fulfilled for successful employment of ASD, are demonstrated through analysis of completed ASD projects.

    Abstract [en]

    The paper is devoted to finding out whether employing the systems perspective can help in converting the tacit knowledge of expert software engineers into an explicit form to be transferred to novices and non-technical stakeholders of the software projects. It suggests a simple framework, dubbed SPC, that is based on distinguishing three interconnected systems involved in a software development projects: the software itself (S), the software project (P), and the context in which the software is or to be deployed (C). The usefulness of the framework is demonstrated on using SPC for determining the area of applicability of the agile software development. This is accomplished by building models of traditional and agile software development projects and analyzing the properties of these models. The models are built based on the knowledge transformation perspective, as the author considers it to be the most differentiating perspective between the agile and traditional software development. For building the models, the ideas from SECI model of Nonaka have been used. In addition, the paper presents some ideas on how the SPC framework can be used for analyzing other issues related to software development.

    Fractal Enterprise Model and its Usage for Business Model Innovation: Tutorial2018Inngår i: Proceedings of the 11th IADIS International Conference Information Systems 2018 / [ed] Miguel Baptista Nunes, Pedro Isaias, Philip Powell, IADIS Press, 2018, s. xvi-xviiiKonferansepaper (Fagfellevurdert)
    Abstract [en]

    This tutorial introduces a new type of enterprise models called Fractal Enterprise Model (FEM), and its usage for industry level Business Model Innovation. The latter means starting a business that is different from the one already run by the enterprise. A FEM model connects enterprise's business processes with its assets revealing existing assets that can be used in a new business model. The assets can be human-related or infrastructure related, including various IT systems that support the business. A new business model is built by finding another usage for already existing assets; it can be a technologically based transformation, or a human capital based transformation, or both.

    Functional Decomposition of a Socio-Technical System: What is Missing?2015Inngår i: STPIS 2015: Socio-Technical Perspective in IS Development: Proceedings / [ed] Stewart Kowalski, Peter Bednar, Ilia Bider, CEUR-WS.org , 2015, s. 114-120Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The paper discusses the needs of new expressive means for modeling a socio-technical system as consisting of functional components that are connected to each-other through the output-input relationships. The discussion is based on an example of depicting so-called feedback connections between the functional components of a system. The need to introduce a feedback connection arises when two connected components are heavily dependent on the intellectual activity of people who man the components. In such a situation, there is a risk that the output from one component could be misinterpreted by the component which takes it as an input. Using a simplified example of a software development project, the paper introduces the notion of a feedback connection and discusses the ways it could be realized in a socio-technical system.

    In Search for a Good Theory: Commuting between Research and Practice in Business Process Domain2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Kurt Lewin’s statement “There is nothing more practical than a good theory” says not so much about what is good for practice, but rather what it means to have a good theory. There exist a number of competing theories in the business process domain. The current paper is devoted to one of those that lie outside the mainstream direction. The purpose of the paper is not to present the theory as such, but to present the stages of how it was developed with the aim of becoming a “good” theory from the practical point of view. The paper is written as an experience report and goes through different stages of the development where research efforts where intermixed with practical tests. The theory in question is the state-oriented view on business processes. The basic idea of this theory lies in application of the general principles of the theory of dynamic systems to the business domain. The main direction for practical application of theoretical results is the development of IT-support for loosely structured business processes. Besides giving the history of the related research and practical efforts, the paper discusses the lessons learned that can be of interest for the development of other theoretical models/views in the business process domain.

    Abstract [en]

    The paper investigates whether the classical socio-technical matrix that differentiate 4 quadrants of social-technical system: people, structure, tasks and technology can still be useful for practical purposes. The paper gives a positive answer on the question, provided that the level of abstraction in defining these four quadrants is increased to deal with culture, type of structure, methods (techniques) and type of technology, as well as the idea of joint optimization is substituted with the idea of alignment. The paper presents some examples where the concept of the augment matrix has been used.

    Abstract [en]

    The keynote overviews the efforts of a group of researchers and practitioners to build and test a theory of business processes (BP) that could be of use for building non-workflow based business processes support (BPS) systems. The background for these efforts lies in two scientific disciplines outside the domain of Business Process Management, namely: Systems Thinking and Mathematical System Theory.

    Towards Process Improvement for Case Management: An Outline Based on Viable System Model and an Example of Organizing Scientific Events2016Inngår i: Business Process Management Workshops: BPM 2015, 13th International Workshops, Innsbruck, Austria, August 31 – September 3, 2015, Revised Papers / [ed] Manfred Reichert, Hajo A.

    Abstract [en]

    There are a number of methods for business process improvement that are used in practice and investigated in theory, such as Lean or Six Sigma. Most of these methods are activity based and they are aimed at optimizing the activities flow, and/or the usage of resources in the process. These methods suit well the workflow-based processes and thinking, but they are not easily adaptable to Case/Adaptive Case Management (CM/ACM) processes, the goal of improvement for which is improving the overall result from the knowledge workers cooperative work. Another distinctive feature of CM/ACM is that the process is guided not through which flow of activities to use in certain situations, but through a set of templates to use in these situations. This paper outlines a possible method of improving CM/ACM processes based on the Viable System Model (VSM). Though the usage of VSM for process improvement has been reported in the literature, it was not specifically applied to CM/ACM processes. The outline is based on the analysis of the process of organizing a series of scientific events, such as the AdaptiveCM workshop.
