    Customers IT Governance maturity: Successful implementation of IS2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis I have tried to identify if there exists a correlation between IT Governance Maturity (ITGM) and the success of an Information system implementation.

    The method chosen for this research was a Case study, performed at an IT-company, Medius AB in Linköping, Sweden. Six customers of Medius where selected, based on their successfulness project implementation, that the same project manager at Medius was involved and that their existed a comparable customer in the same industry for each customer selected.

    Out of the six customers selected for this thesis, two of them where from the retail industry, two from the manufacturing industry and two from the service industry. Their maturity level (according to SAMM) was determined using the framework suggested by Khaita & Zaulkernan (2009), by estimating each attribute from the interviews performed with the respondents.

    Each customers ITGM level was then compared to the degree of success of the implementation project of the Medius system. A correlation was found, between high ITGM and successful outcomes of the implementation project. The two attributes that seem to affect the outcome the most was: communication and knowledge sharing. These two attributes was also the ones least implementeted at the customers which unsuccesfully implemented the system.

    Detection and interpretation of weak signals2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Managing safety at a nuclear power plant is about a complex system with demanding technology under time pressure where the cost of failure is exceptionally high. Swedish nuclear power plants have over the last few years introduced Pre-job Briefing and other so called Human Performance Tools to advert errors and strengthen control. By using the Systemic Resilience Model different views of safety are taken to understand the origin of the signals that leads to a Pre-job Briefing, and how the signal is interpreted, re-interpreted, and presented.

    The study took place at a Swedish nuclear power plant and included four days of observations and 20 interviewees. The thematic analysis shows a similarity between mentioned origins of Pre-job Briefings and the intended use of Pre-job Briefing. Characteristics of a High Reliability Organisation is shown in practice by a culture of that one will to have a Pre-job Briefing is enough, that sharp end workers is used as a valuable resource for safety and a systematic support to screen jobs over time without influencing non-job related factors.

    The signals acted upon matched well with the intended, and personnel get several opportunities to evaluate the signals together, striving for best possible circumstances. The Systemic Resilience Model was successfully applied together with a thematic analysis, which strengthens its validity as a holistic model that combines different views of safety in one coherent model. SyRes allowed to present additional themes, leaving the question at what stage SyRes is optimally implemented in a thematic analysis.

    Smart Cylinder: Konceptstudie samt demonstrator för systemövervakning av hydraulcylindrar2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    This master thesis work is done at the Department of Mechanical Engineering, the division of Fluid and Mechanical Engineering Systems at Linköpings University in cooperation with CA-Verken AB in Sävsjö.

    The thesis is the first step into the development of a new kind of hydraulic cylinder, a hydraulic cylinder with built-in system monitoring capabilities. The thesis work has been consisting of a theoretical concept analysis of system and health monitoring in hydraulic cylinders and construction of a demonstrator, a hydraulic test rig, in which the ideas and conclusion from the theoretical study are to be verified. The concept analysis along with the construction of the demonstrator has resulted in several suggestions how to design the future hydraulic cylinder.

    New Forms of Collaboration in Emergency Response Systems: A framework for participatory design of information systems2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    An emergency response systems (ERS) is usually responsible for delivering essential services to save lives and minimise environmental damage in case of small, frequent or large-scale emergencies. The ongoing global financial crisis, lack of professional resources, public sector cuts and rising public expectations are some of the challenges ERSs currently are facing. At the same time, societal trends in form of large-scale disasters such as tsunamis, storms, forest fires, terror attacks, and wars in the Middle East leading to mass migration have intensified recently and globally, increasing demand for these services in the public sector. As a result, emergency response actors are often under extreme pressure, and may need to seek assistance from and cooperate with other resources in society in order to become more effective. An emerging trend in ERSs in response to the challenges, in Sweden and internationally, is to create new forms of collaboration in emergency management (e.g., cross-sector collaboration, involving citizens in e-government, and involving volunteers). While research and practice have started to show the benefits of organising ERSs in new ways, the increasingly broad set of heterogeneous stakeholders involved in the collaborations introduce various challenges. Legal issues, unclear responsibilities of actors, difficulty in the categorisation of tasks, job insurance problems, diversity in education and background of actors, and difficulty determining actors’ specific needs for IS support are some examples. Analysis of collaborations thus becomes increasingly complex, and must incorporate many aspects. Rudimentary analyses may result in failure of related projects and IS development, and ultimately in less effective collaborations. New forms of collaboration must therefore be analysed and understood rigorously, generally and in each specific context in order to develop them for ERSs and the public sector and to support actors with effective IS tools.

    This thesis develops and presents a framework for analysing new forms of collaboration in ERSs. It also provides an initial suggestion on how to apply the framework with a specific focus on IS development. The study was carried out as a qualitative case study based on three kinds of collaboration in the Swedish ERS: co-operative, cross-sector use of resources, involving civil volunteers in response operations and co-location of actors. The framework has fifteen dimensions. They are: Type/Role, Attitude, Training, Background, Task and Responsibility, Availability/Accessibility, Incident Type, Communication Methods, Information Technology, Emergency Supplies, Organisational Structure, Leadership, Costs/Benefits, Environment, and Regulations and Legal Issues. Sociotechnical systems theory and participatory design principles were applied to make the framework usable in the IS field. The framework can be used generally to analyse new forms of collaboration in ERSs in order to understand its different aspects and emergent challenges, such as actors’ tasks, relevant laws, leadership and organisational factors, which may otherwise be overlooked, into the analysis process. As to IS development, the framework can contribute to organisational analysis and needs analysis in the participatory design of IS for ERSs, e.g. by helping to identify key stakeholders and involve them in the development process.

    The framework was initially tested at the co-location case and showed several promising benefits in terms of identifying and involving stakeholders in the development process. It was deemed helpful in determining and formulating interviews, observations, and future workshops in order to explore and study all relevant dimensions of the collaboration in the early phases of participatory design. It was also felt that the framework saved time and resources. It is argued that it may offer similar benefits in similar cases, although this will require further testing with more case studies. A standardised and developed version of the framework may also be adapted to be applicable to other public sector contexts such as e-government in which new forms of collaboration and governance are in focus. Such a framework may also help to address general challenges often associated with participatory design, add formalisation to it, and contribute to shift it from an academic to a practical approach in order to derive its benefits in complex environments. The next step will be to use the framework as a departure point for analysing the potential co-operative use of resources and cross-sector collaboration in the project ‘Efficient Communal Use of Municipal Resources for Increased Safety and Security’ (ESKORT) in the municipality of Norrköping.

    2013 (English)In: ISCRAM2013. Conference Proceedings, Book of Papers, 10th International Conference on Information Systems for Crisis Response and Management / [ed] T. Comes, F. Fiedrich , S. Fortier, J. Geldermann and T. Müller, 2013, p. 741-746Conference paper, Published paper (Refereed)
    Abstract [en]

    Using actors from different societal sectors can improve the response operation quality in emergency management. The different roles, tasks and responsibilities these actors have in response operations and the legal frameworks they work within influence their needs for proper information system support. There is thus a substantial need to study and systemize the concept of “new actors” before providing them with technical solutions. In this study, a framework is constructed showing 14 dimensions of new actors that need to be considered when new actors are studied in more detail.

    Abstract [en]

    Co-location as a form of network governance is a way of organizing response teams when responding to an emergency situation. At the ‘Safety house’ in the province of Jämtland in Sweden main emergency response actors and supporting actors work together in a shared physical place in order to facilitate the process of cooperation and joint decision making. In order to identify the strengths, weaknesses, obstacles, needs and information system role, we explored this case by looking at how the involved actors experience this new working context. We applied an analytical framework developed specifically for new forms of emergency response. It was found that co-location of actors increases the efficiency in using professional response resources and shortens the emergency response time. Information systems can have a significant role in improving the collaboration between actors at the ‘Safety house’. However secrecy issues, the problem of control and politics and the evaluation of the performance of actors are major challenges which face further development of the co-location concept.

    Actor-centred emergency response systems: a framework for needs analysis and information systems development2016In: International Journal of Emergency Management, ISSN 1471-4825, E-ISSN 1741-5071, Vol. 12, no 4, p. 403-434Article in journal (Refereed)
    Abstract [en]

     A new trend in emergency response systems (ERS) is to create new forms of collaboration, for example, by involving new resources in response operations, in order to compensate for the limited number of professional resources. However, the fact that the new resources may come from different organisational contexts and social sectors creates new challenges which directly affect information systems development for these resources. This study presents a framework including 15 dimensions to analyse the new forms of collaboration. Socio-technical system theory and participatory design approaches are applied to make the framework applicable in the information systems field. The framework might also address general problems such as the lack of formalisation and difficulties in identifying relevant stakeholders in participatory design. A comparison with international research showed a potential to adapt the framework to ERSs in other countries or even to other parts of the public sector that are undergoing similar changes.

    An Unsupervised Data-driven Method to Discover Equivalent Relations in Large Linked Datasets2017In: Semantic Web, ISSN 1570-0844, E-ISSN 2210-4968, Vol. 8, no 2Article in journal (Refereed)
    Abstract [en]

    This article addresses a number of limitations of state-of-the-art methods of Ontology Alignment: 1) they primarily address concepts and entities while relations are less well-studied; 2) many build on the assumption of the well-formedness of ontologies which is unnecessarily true in the domain of Linked Open Data; 3) few have looked at schema heterogeneity from a single source, which is also a common issue particularly in very large Linked Dataset created automatically from heterogeneous resources, or integrated from multiple datasets. We propose a domain-and language-independent and completely unsupervised method to align equivalent relations across schemata based on their shared instances. We introduce a novel similarity measure able to cope with unbalanced population of schema elements, an unsupervised technique to automatically decide similarity threshold to assert equivalence for a pair of relations, and an unsupervised clustering process to discover groups of equivalent relations across different schemata. Although the method is designed for aligning relations within a single dataset, it can also be adapted for cross-dataset alignment where sameAs links between datasets have been established. Using three gold standards created based on DBpedia, we obtain encouraging results from a thorough evaluation involving four baseline similarity measures and over 15 comparative models based on variants of the proposed method. The proposed method makes significant improvement over baseline models in terms of F1 measure (mostly between 7% and 40%), and it always scores the highest precision and is also among the top performers in terms of recall. We also make public the datasets used in this work, which we believe make the largest collection of gold standards for evaluating relation alignment in the LOD context.

    Information Systems Actability: Understanding Information Technology as a Tool for Business Action and Communication2003Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This dissertation is devoted to a perspective from which IT-based information systems are conceived as information technological artefacts intended for business action and communication. The perspective has been made concrete through the concept of information systems actability, which is the main concept under scrutiny. The research contributions of the dissertation exist at various levels of abstration. First of all, the dissertation contributes to the understanding of information systems from a social action perspective. Based on identified weaknesses in contemporary conceptualizations of information systems, the concept of information systems actability is developed. This contribution consists of a reconciliation of various views on information system usage quality with its roots in a linguistic tradition including elements from organizational semiotics and the language/action perspective. At a more concrete level, this understanding, and the concept as such, have consequences for the development and evaluation of information systems. Such consequences have been the foundation for a proposed information systems design method, which thus constitutes a further contribution. Another contribution is the outlining of an information systems actability. As a further means of obtaining empirical experience of working with this concept, a descriptive analytic framework has been developed, which constitutes yet another contribution. These three operationalizations, the design method, the evaluation method and the analytic framework, have been developed and empirically grounded through a qualitative case study appproach involving four cases of information systems requirements specification, four evaluations of existing information systems, and two cases of description and characterization of information systems related phenomena from the perspective of actability. The latter two cases imply how further contributions at an even more concrete level, constituted by characterizations of Internet-based information systems and the local electronic marketplace, seen in the light of information systems actability.

    Standardisering kontra flexibilitet: En fallstudie av utvecklingsprocesser2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization. Further on it gives a perspective on how IT and processes should be integrated as well as a perspective on quality in processes.The result of this study shows that Saab focus on standardization of milestones, concepts and language, when designing processes for development. Through this, they want to accomplish better collaboration. The study also shows the difficulties in development processes compared with production. The main differences are that development processes needs to have built in flexibility and room for the employees to take initiatives. This makes it hard to standardize mode of operation, in a development process. For IT to be a support for the development process, it requires an adaptation of both the process and IT systems. On Saab there are different opinions on how the adaption should be organized. This study points out some specific reasons that it is hard to predict it the system or the process should be adapted. Instead, common sense should be used while adapting IT and process.
