    ICT challenges of Integrated care from a Co Design perspective using a Quadraple Helix2020In: International Journal of Integrated Care, ISSN 1568-4156, E-ISSN 1568-4156Article in journal (Refereed)
    Abstract [en]

    The Internet of Things (IoT) plays a vital role in today’s medicine (Islam et al, 2015). In 2020, 40% of IoT-related technologies will be assigned to the health domain, which makes up around a 117 $ billion in the global market (Bauer, Patel & Veira, 2016). Adding to this the demographic changes will further set a significant challenge in Europe (Steinführer & Haase, 2007). Innovative techniques for supporting health systems and independent life for the aging population is therefore essential, not at least in relation to fall prevention and technology for promoting a good life throughout the lifespan. Further, participation from patients is a goal for healthcare worldwide (Lundgren, Sunesson & Tunved, 2014). For example according to the Health and Medical care act in Sweden (1982:763) it is described that the goal for health care “is good health and care on equal terms for the entire population”. In line with this challenge of integrated care the patient itself will be the most important resource for promotion of health, why Co Design is needed as a method for innovation in healthcare sector. It is important for the users ‘experiences and insights to contribution in improvements but not at least because it has been shown that increased involvement with the user in care reduces the number of hospital visits (Simpsons, 2007).

    Abstract [en]

    This bachelor thesis is a case study about cloud computing and specifically on finance applications. We have found out the reasons why not more small business owners moves to web-based solutions, since today it´s very popular to work in the cloud. Cloud services are a relatively new way of working and that means big changes for businesses while offering more opportunities than before. The purpose of this essay is to highlight the reasons why not more business owner’s uses web solutions and what benefits there are with web solutions. Our investigation is directed only into themselves against financial applications but can most likely be used in a more general context. To carry out the research we have used a case study where we have interviewed several users to the each approaches. The approaches we have investigated are desktop applications and web-based applications. The results after our data collection reveals a number of factors that play a large role in the choice between the different modes. Our survey shows that many users are afraid of what the cloud is and where their information actually goes. The result is also in on several advantages of web solutions, including that it is better availability and cost.

    Från förberedelse till upplevelse: Hur användarupplevelsen i e-handel kan efterlikna upplevelsen från en fysisk butik med fokus på single brandföretag2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose

    The purpose of this study was to examine which aspects of experience that consumers experience in a physical single brand store that should be emulated and lifted into the same corporate digital store. It has also been to see how well companies communicate their core values to their consumers in the physical store. Finally, I examined what’s important when it comes to features, functions, and generally experience for consumers when shopping online in general.

    Research questions

    What makes this study particularly interesting is that the single brand companies in this study have a physical and digital store where they sell their products, but they also have resellers who sell the same products and thus becomes their competitors. Since these single brand companies have a brand quality and core values that they need to live up to, they can’t reduce the prices of their products in the same way their retail stores do. Would the solution be to try to simulate the experience consumer’s get in the physical store into the digital store to convey a good brand experience?

    Conclusion

    This study was based on a model that describes how a good user experience can be created. The results have shown that companies need to work more with the user experience in their digital store. They could achieve this by working more actively with their consumers and try to understand who they are and how they look at their brand. Based on the outcome, work more actively to meet their consumer’s goals but also their own goals.

    Information literacy and informed learning: conceptual innovations for IL research and practice futures2017In: Journal of Information Literacy, ISSN 1750-5968, E-ISSN 1750-5968, Vol. 11, no 1, p. 4-22Article in journal (Refereed)
    Abstract [en]

    Our paper draws together conceptual innovations emerging from the work of a group of researchers focussed on the relational approach to information literacy, more recently labelled ‘informed learning’. Team members have been working together in various configurations for periods ranging from seven to seventeen years. Our collaborative approach continues to yield new concepts and constructs which we believe to be of value to ongoing research and practice. Some of the ideas discussed have been previouly published, while others are being put forward for the first time. All are significant in that they together form new constructs that have emerged from a focus on the relational approach to information literacy. In this paper, Christine Bruce introduces the background to this work and the contributing researchers. Then the individual authors present the key directions which they have developed and are leading, typically working with one or more of the wider network. The key ideas presented are: The expressive window for information literacy (Mandy Lupton); information experience design (Elham Sayyad Abdi); cross-contextuality and experienced identity (Andrew Demasson); informed learning design (Clarence Maybee); spaces for inclusive informed learning (Hilary Hughes); and informed systems (Mary Somerville and Anita Mirjamdotter).  In each piece, authors reflect on what the idea is about, where it came from and what it might mean for research and practice.

    Abstract [en]

    The existence for companies today consists of constant challenges with customers that want more individual products with high quality as quickly as possible. For a company to be able to have a short delivery time, it must also have a short production time. This makes streamlining and improvement of processes a big part of a company’s work

    This thesis has been carried out together with the company Lasermax Roll Systems AB, a world-leading manufacturer of feeding, finishing and monitoring systems for high-speed digital printers. They manufacture their products according to the assembling for costumer order principle.

    The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB. The mapping of the processes shall result in flowcharts and identifying problems in the processes, which can be used for working with improvements.

    The information for the result has been gathered by interviews of key persons in the processes and studies of existing information at Lasermax Roll Systems AB. Later on the empirical information has been analyzed by comparing with literature from the theoretical part.

    The thesis resulted in flowcharts over the production processes, assembling and test. Also three problem areas were identified which can be used for working with improvements. The three areas are: items and suppliers, control of review and testing of the products.

    Conclusions of this thesis are that working with mapping of processes is very good för companies today to become more effective and improve their business. It is also important for the companies to see the overall picture of their business and work with it, from suppliers to the costumer, together, to be able to deliver a product on time with good quality.

    Abstract [en]

    The amount of information has increased as a result of the technological development and it has become common to perceive information overload. This area is researched in office environments, however, we found no research in telecommuting. Low quality of information has been found through previous research as being one of the main reasons why we are experiencing information overload. In previous research, students were able to conclude that there was no research on the office and telecommuting experienced information overload. This study's problem is based on a scientific problem, were the students intended to examine how work in offices are perceived compared to teleworking in aspects of information quality and information overload. To illustrate the problem a qualitative method was selected. The study is based on semi-structured telephone interviews with five participating informants. This study's found that office environments contributed with more irrelevant information because of verbal communication. The students also came to the conclusion that the concepts of information quality and information overload are related to each other, but information quality is the overlying concept. Lack of information quality contributes to experienced information overload.

    ICT tools for e-maintenance2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Information and Communication Technologies (ICT) have made an impact on various parts of a company. The need of many companies of integrating the wealth of information and processes for profitable business has been highlighted since the middle of the 1980s. Further, the commercialization of the Internet began during the middle of the 1990s. The combinations of these developments and the positive impact of ICTs on maintenance and thereby on productivity have been, lately, realized by academia and industry alike, and a new concept, e-maintenance, has been coined.

    The main problem of the present work was "How ICT can be used for integrating various data and information to provide better decision support and improve productivity". The main problem addressed was divided into three sub research questions. (1) Which approach should be considered to develop e-maintenance systems? (2) How can web and agent technologies be used in e-maintenance? (3) Which ICT architecture and ICT tools should be used to enhance productivity in the organization/maintenance department and the decision-making process? The research process in this study was based on design science, .i.e. constructive research approach. However, during the first phases of the study has empirical studies been conducted to get an overall understanding of the domain of study.

    The present study first presents the state of the art. It was found that in many research projects the application of ICTs to condition-based maintenance (CBM) has been part of the whole work. Since CBM is the most desirable maintenance strategy it needs more focused attention. However,it was found that limited consistent and systematic efforts have been made, in an isolated manner,in industry and academia. A few researchers are using mobile devices, especially personal digital assistants (PDA) with embedded technology and even fewer with web technology.

    The study continues by presenting e-maintenance solutions. It goes through the modelling phase in the development of a system and suggests an ontology approach. Further, the use of web and agent technologies on a conceptual level was studied and an architecture was proposed for the same purpose, i.e. e-maintenance. Finally, a prototype was developed with the use of the ICTs tools and an architecture was proposed, Web and mobile architecture. It is an n-tier architecture, where the main client was a mobile device, i.e. PDA. The developed system with the use of various ICTs, viz. web technology, mobile device and wireless communication is believed to make maintenance personnel more productive and help to achieve better decisions.

    Information Systems development aspects for the mobile web technologies2015In: Social Technologies, ISSN 2029-7564, E-ISSN 2029-7564, Vol. 5, no 1, p. 62-72Article in journal (Refereed)
    Abstract [en]

    Purpose – The paper goes through and outlines the developments of IS methodologies as well as certain research approaches applied. In addition, the technical aspects of the ICT architectures are discussed for purposes of the development and implementation of the mobile web technologies for the industrial domain.

    Design/methodology/approach – The author organizes the relevant literature findings in three sections named the ICTs in the industrial maintenance domain, web oriented architecture and the IS development methodologies. The findings are analysed and discussed while highlighting aspects of the ICT architectures, IS methodologies and different approaches that one needs to be aware of for successful design and implementation of the mobile web technologies.

    Findings – The results reveal that mobile technologies have been developed mainly with the prototype and design approach where emphasis has been on the technical aspects. For the above mentioned reason the author reviews the area of the IS development methodologies as well as the ICT architectures, which shows rapid and dynamic process over time. In addition, it was found that for successful planning, implementation and use of the mobile web technologies it is important to emphasize other aspects and not justthe technological ones. The research approaches that shed light on the IS development process are the Action design research as well as Participatory design approach.

    Research limitations/implications – The current work presented in this paper hows that to develop sustainable ICTs, especially mobile web technologies for the industrial domain, there is a need to consider various aspects which put an emphasis on not just the technological aspects of the developed systems but also, for instance, on the organizational context as well as the user’s needs and various stakeholders. It is, therefore, important to choose proper IS methodologies, tools, techniques and approaches for sustainable ICTs in the domain of interest.

    Practical implications – The current work pinpoints important aspects to understand and consider when choosing the IS methodology, tools and techniques for the mobile web technologies.

    Originality/Value – The paper pinpoints important characteristics to consider when planning to develop and implement mobile web technologies into the industrial maintenance engineering domain.

    Industrial open source solutions for product life cycle management2014In: Cogent Engineering, ISSN 2331-1916, Vol. 1, no 1, article id 939737Article in journal (Refereed)
    Abstract [en]

    The authors go through the open source for product life cycle management (PLM) and the efforts done from communities such as the open source initiative. The characteristics of the open source solutions are highlighted as well. Next, the authors go through the requirements for PLM. This is an area where more attention has been given as the manufacturers are competing with the quality and life cycle costs of their products. Especially, the need of companies to try to get a strong position in providing services for their products and thus to make themselves less vulnerable to changes in the market has led to high interest in product life cycle simulation. The potential of applying semantic data management to solve these problems discussed in the light of recent developments. In addition, a basic roadmap is presented as to how the above-described problems could be tackled with open software solutions.

    The challenges of cybersecurity frameworks to protect data required for the development of advanced maintenance2016In: Product-Service Systems Across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 222-227Conference paper (Refereed)
    Abstract [en]

    The main objective of the paper is to highlight the important aspects of the data management in condition monitoring and maintenance, especially when the emergent technologies, such as the cloud computing and big data, are to be considered in the maintenance department. In addition, one of the main data management elements highlighted in the current work are the cybersecurity issues which might be one of the biggest obstacles hindering the development of cloud based big data for condition-based maintenance (CBM) purposes. Further, the benefits and current risks of storing a company's data in the cloud are highlighted. The authors discuss as well different data needs in various processes in the area of asset management. In addition, the challenges and issues to be addressed for the optimal use of the company data at the cloud together with the big data approach are addressed. This is seen as an important part in an effort to achieve sustainable information and communication technologies for the industry.

    Engineering Emergent Semantics into Pervasive Resource Discovery2012In: 39th Euromicro Conference on Software Engineering and Advanced Applications, IEEE Press, 2012, p. 208-215Conference paper (Refereed)
    Abstract [en]

    Pervasive environments are composed as spontaneous aggregation of heterogeneous and independent devices, which may seamlessly consume, but also provide, software resources over the network. As result, applications emerge from the dynamic composition of the resources available within the environment. This requires applications of being semantic-aware, to reason about and learn from the environment. However, due to the inherent high degree of dynamism characterizing pervasiveenvironments, semantics cannot be established a-priori, rather it should "emerge" from online negotiations among involved parties. This paper, formalizes emergent semantics principles into formal foundations, and shows, as proof of concept, how to engineer such foundations into a fully distributedsemantic service discovery.

    Microevolution of Pervasive Services2013In: 40th Euromicro Conference on Software Engineering and Advanced Applications, IEEE Press, 2013, p. 161-168Conference paper (Refereed)
    Abstract [en]

    The pervasive computing vision of the future communication infrastructure is that we will be everywhere connected with invisible devices, which may consume and provide computational resources over the network. Resources are often abstracted as autonomous services, which must be "continually" evolved at run time to satisfy changing requirements. This paper discusses the design, development and evaluation of the Microevolution of Pervasive Services framework, which aims at supporting the run-time small-scale evolution of services through code mobility. Indeed, the framework provides (i) a dispatching mechanism to migrate Java code throughout the pervasive networking environment, and (ii) a microevolution manager that exploits Java reflection mechanisms to optimize code transmission.

    An Experience in Evaluating Publish/Subscribe Services in a Wireless Network2002In: Proceedings of the 3rd International Workshop on Software and Performance, ACM Press, 2002, p. 128-133Conference paper (Refereed)
    Abstract [en]

    As wireless technology becomes more available, developers of distributed applications are becoming more interested in how that technology affects the performance of their systems. We have developed a distributed publish/subscribe communication service initially hosted on the standard IP-wired network infrastructure, but would now like to rehost that service onto a GPRS wireless network. This paper reports on our experience in attempting to evaluate the performance of the service using an available emulation environment. Our conclusion from our experience to date is that current tools do not model the wireless network at an appropriate level of abstraction. In particular, they do not allow us to study the integration of individual publish/subscribe service-layer elements with GPRS network-layer elements, nor do they allow us to study multiple GPRS clients interacting over the network. Instead we were limited to results related to the interaction between an individual GPRS client and the GPRS network modeled as a monolith.

    Design and Evaluation of a Support Service for Mobile, Wireless Publish/Subscribe Applications2003In: IEEE Transactions on Software Engineering, ISSN 0098-5589, E-ISSN 1939-3520, Vol. 29, no 12, p. 1059-1071Article in journal (Refereed)
    Abstract [en]

    This paper presents the design and evaluation of a support service for mobile, wireless clients of a distributed publish/subscribe system. A distributed publish/subscribe system is a networked communication infrastructure where messages are published by senders and then delivered to the receivers whose subscriptions match the messages. Communication therefore does not involve the use of explicit addresses, but rather emerges from the dynamic arrangement of publishers and subscribers. Such a communication mechanism is an ideal platform for a variety of Internet applications, including multiparty messaging, personal information management, information sharing, online news distribution, service discovery, and electronic auctions. Our goal is to support such applications on mobile, wireless host devices in such a way that the applications can, if they chose, be oblivious to the mobility and intermittent connectivity of their hosts as they move from one publish/subscribe access point to another. In this paper, we describe a generic, value-added service that can be used in conjunction with publish/subscribe systems to achieve these goals. We detail the implementation of the service and present the results of our evaluation of the service in both wireline and emulated wireless environments.

    Resource-Oriented Middleware Abstractions for Pervasive Computing2012In: International Conference on Software Science, Technology and Engineering, IEEE Press, 2012, p. 1-10Conference paper (Refereed)
    Abstract [en]

    The pervasive computing vision of the future communication and computational infrastructure is that we will be everywhere virtually connected with invisible computers, embedded in the environment. In this context, the challenge is to provide a middleware support that allows applications to have minimal assumptions about the environment while being able to dynamically adapt to the surrounding context. Specifically, the middleware should (i) deal with the run-time growth of the application in terms of involved resources (flexibility), (ii) accommodate heterogeneous and unforeseen functionalities into the running application (genericity), and (iii) discover new functionality at run time and rearrange the application accordingly (dynamism). To this extent, we devised the P-REST (Pervasive REST) architectural style and built the P RIME (P-rest Runtime) middleware to support it. PRIME allows a quick and effective development and execution P-REST applications by leveraging functional programming and code mobility.

    RESTful Service Architectures for Pervasive Networking Environments2011In: REST: From Research to Practice / [ed] Wilde, Erik; Pautasso, Cesare, Springer, 2011, p. 401-422Chapter in book (Refereed)
    Abstract [en]

    Computing facilities are an essential part of the fabric of our society, and an ever-increasing number of computing devices is deployed within the environment in which we live. The vision of pervasive computing is becoming real. To exploit the opportunities offered by pervasiveness, we need to revisit the classic software development methods to meet new requirements: (1) pervasive applications should be able to dynamically configure themselves, also benefiting from third-party functionalities discovered at run time and (2) pervasive applications should be aware of, and resilient to, environmental changes. In this chapter we focus on the software architecture, with the goal of facilitating both the development and the run-time adaptation of pervasive applications. More specifically we investigate the adoption of the REST architectural style to deal with pervasive environment issues. Indeed, we believe that, although REST has been introduced by observing and analyzing the structure of the Internet, its field of applicability is not restricted to it. The chapter also illustrates a proof-of-concept example, and then discusses the advantages of choosing REST over other styles in pervasive environments.

    ubiREST: A RESTful Service-Oriented Middleware for Ubiquitous Networking2014In: Advanced Web Services / [ed] Bouguettaya, Athman; Sheng, Quan Z.; Daniel, Florian, Springer, 2014, p. 475-500Chapter in book (Other academic)
    Abstract [en]

    The computing and networking capabilities of today’s wireless mobile devices allow for seamlessly-networked, ubiquitous services, which may be dynamically composed at run-time to accomplish complex tasks. This vision, however, remains challenged by the inherent mobility of such devices, which makes services highly volatile. These issues call for a service-oriented middleware that should (i) deal with the run-time growth of the application in terms of involved services (flexibility), (ii) accommodate heterogeneous and unforeseen services into the running application (genericity), and (iii) discover new services at run time and rearrange the application accordingly (dynamism). This chapter discusses the design and implementation of ubiREST, a service-oriented middleware that leverages REST principles to effectively enable the ubiquitous networking of Services.ubiREST specifically defines a layered communication middleware supporting RESTful Services while exploiting nowadays ubiquitous connectivity.

    Formal Analysis of Architectural Patterns2004In: Software Architecture: Proceedings First European Workshop, EWSA 2004, St Andrews, UK, May 21-22, 2004 / [ed] Oquendo, Flavio; Warboys, BrianC.; Morrison, Ron, Springer, 2004, Vol. 3047, p. 10-24Chapter in book (Other academic)
    Abstract [en]

    Architectural patterns characterize and specify structural and behavioral properties of (sub)systems, thus allowing the provision of solutions for classes of problems.

    In this paper we show the use of architectural patterns as an abstraction to carry on, and reuse, formal reasoning on systems whose configuration can dynamically change.

    This kind of systems is hard to model and to reason about due to the fact that we cannot simply build a model with fixed topology (i.e. fixed number of components and connectors) and validate properties of interest on it.

    The work presented in this paper proposes an approach that given an architectural pattern which expresses a class of systems configurations and a set of properties of interest (i) selects, if any, aminimal configuration for which the specified properties make sense, (ii) an abstraction of the chosen architectural model erformed, in order to reduce the complexity of the verification phase. In this stage, abstractions are driven by the properties of interest. The output of this abstraction step can be model-checked, tested and analyzed by using a standard model-checking framework. (iii) The verification results obtained in the previous step are lifted to generic configurations by performing manual reasoning driven by the constraints posed by the architectural pattern.

    The approach will be applied by using an event-based architectural pattern to a publish/subscribe system, the Siena middleware, in order to validate its features and its mobility extension.

    ubiSOAP: A Service Oriented Middleware for Seamless Networking2008In: Service-Oriented Computing “ ICSOC 2008: Proceedings of 6th International Conference, Sydney, Australia, December 1-5, 2008 / [ed] Bouguettaya, Athman; Krueger, Ingolf; Margaria, Tiziana, Springer, 2008, Vol. 5364, p. 195-209Chapter in book (Other academic)
    Abstract [en]

    The computing and networking capacities of today’s wireless portable devices allow for pervasive services, which are seamlessly networked. Indeed, wireless handheld devices now embed the necessary resources to act as both service clients and providers. However, the seamless networking of services remains challenged by the inherent mobility and resource constraints of devices, which make services a priori highly volatile. This paper discusses the design, implementation and experimentation of the ubiSOAP service-oriented middleware, which leverages wireless networking capacities to effectively enable the seamless networking of services. ubiSOAP specifically defines a layered communication middleware that underlies standard SOAP-based middleware, hence supporting legacy services while exploiting nowadays pervasive connectivity.

    IoT-enabled Physical Telerehabilitation Platform2017In: Proccedings of the International Workshop on Engineering IoT Systems: Architectures, Services, Applications, and Platforms, IEEE, 2017, p. 112-119Conference paper (Refereed)
    Abstract [en]

    Physical telerehabilitation services over the Internet allow physiotherapists to engage in remote consultation with patients at their homes, improving the quality of care and reducing costs. Traditional visual approaches, such as webcams and videophones, are limited in terms of precision of assessment and support for assistance with exercises. In this paper, we present a Physical Telerehabilitation System (PTS) that enhances video interaction with IoT technology to monitor the position of the body of patients in space and provide smart data to physiotherapists and users. We give an overview of the architecture of the PTS and evaluate (i) its usability based on a number of interviews and focus groups with stakeholders, and (ii) its technical efficiency based on a series of measurements. From this evaluation, we derive a number of challenges for further improvement of the PTS and outline a possible solution based on a microservices architecture.

    Designing New Social Media Services For Seniors’: A Participatory Design Approach2015Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    The society is getting older. A process called aging at the bottom will come with demographic and consequently socio economic changes. Due to this tide wave of elderly I have focused my research on seniors and the need for designing new social media services for them. This thesis is focused an understanding senior’s daily life, their activities, their relationship with their family, friends and groups of interest, how are they currently using the technology and finally to find out with them possibilities for alternative social media services that can sustain or enhance their social engagement and participation. A participatory design approach has been used for the research. Different techniques like cartographic mapping future workshops, walkthrough and diary are the methods that I have chosen for the collection of data. Data gathers is analyzed through the usage of thematic analysis and the main thematic has been presented by the original expressions of seniors during the workshops. Social media is still in its begging when it comes to services for seniors and the opportunities available are huge. This research can be considered a good start also for further services in the future.

    Kravhantering i praktiken: Grundad teori vid insamling och analys av krav samt användarens uppfattning av den informella modellen.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In order to increase interest and knowledge about requirements engineering, this study has tested a requirement method by Halaweh (2012) in a case study. A particular feature of the method is that it uses grounded theory in the analysis of data collection. The requirements are then visualized with an informal model.  A qualitative study has been conducted with the purpose of examining the different types of requirements that the method identifies in the requirement elicitation. Furthermore, to investigate whether the informal model that the  method resulted in represents the requirements collected. The method chapter was divided into two parts, the first part consisting of the case study, where a requirements elicitation was conducted using the requirements method in an organization. The second part consists of the informal model that the requirements method resulted in and which was then displayed to the respondents from the claim collection.  The conclusion of the outcome of this study is that the requirements method identifies functional requirements, non-functional requirements as well as business requirements. Functional requirements are the requirements that have the biggest focus in the requirements method. The requirements method also managed to capture the needs of users and the informal model represented the users needs in a good way and was considered easy to understand. Using the requirements method, focuses on the user in the requirements process resulting in a sociotechnical system that supports the user's tasks. Increased work efficiency for users, users' attitude to work tasks, and user well being are effects of using the requirements method.

    Påverkande faktorer på det individuella beteendet till att dela explicit kunskap: en fallstudie på ett nationellt företag2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a research about how the factors individual attitude, normative conceptions, motivation and organizational climate is influencing factors of encoded explicit knowledge sharing. The flow of sharing means that an employee has knowledge and share it with others in an IT-system as stored information which will be available to others to use. This thesis has been examined in a small to medium sized company in Sweden. Qualitative interviews have been performed with employees in a company, where the employees are responsible to share explicit knowledge in an IT-system. Some researchers believe that if the information is already encoded and acquired it can be used. However, it has been demonstrated that this does not have to be the case. In small and medium sized companies’ information is stored in multiple locations, which makes it difficult for the employees to use the knowledge. The framework Theory of Reasoned Action [TRA] has been used to understand the individual behavior based on the individual attitude, which has been developed with previous research in knowledge sharing where TRA has been used. Our result shows that the factors have an influencing effect on the behavior of sharing encoded explicit knowledge. The internal motivation proved to be an important element to motivate the behavior to share knowledge. Another aspect was the structure in the IT-system for knowledge sharing. The structure had an influencing effect on the behavior, which was not raised in the framework TRA. These factors have been identified from the employee’s perspective in the company, to be the deciding factors that affect sharing of encoded explicit knowledge.

    Academic library managers’ use of artefacts in their everyday cooperative work practices 2019In: Proceedings of 17th European Conference on Computer-Supported Cooperative Work: The International Venue on Practice-centred Computing and the Design of Cooperation Technologies: Doctoral Colloquium Papers, European Society for Socially Embedded Technologies (EUSSET) , 2019, Vol. 2, p. 1-8Conference paper (Refereed)
    Abstract [en]

    This interpretive focused-ethnographic study was conducted to illuminate and gain deeper understanding on managers’ everyday cooperative work practices using artefacts. In the dissertation, artefacts refer to digital technologies and information. The doctoral research specifically examines how artefacts in the workplace of an academic library are used in academic library managers’ everyday cooperative work practices; and provide suggestions of how artefacts can be used to better fit those practices. The empirical data was collected through participant observations, face-to-face interviews and documents from two technologically advanced academic libraries, one in Sweden and another one in Australia. The study uses soft systems thinking theory and concepts from computer-supported cooperative work (CSCW) such as awareness, articulation and appropriation to analyze and discuss how cooperative work is conducted in the everyday work practices of academic library managers with the use of artefacts. Thus, this research contributes insights from the field of computer-supported cooperative work to the information systems and library domain by considering social aspects of cooperative everyday work practices.

    Exploring Knowing in Practice: An Ethnographic Study of Teams in the Agile Setting2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Studies related to knowledge often fall under the traditional knowledge management discourse which views knowledge as a static and transferable entity. However, the predominant knowledge in agile software development is tacit and resides in the heads of individuals with the expertise. The study acknowledges the importance of human agency and moves away from the view of knowledge as a static entity to the perspective of “knowing” which is constituted in our daily actions and practices. The focus is to examine how “knowing” or knowledgeability is enacted through the practices of teams in agile projects.

    A conceptual model was developed from current literature and used as a guide for data collection and analysis. The study subscribed to phenomenological hermeneutics as the philosophical tradition to interpret meaning and the worldviews of the participants. Ethnographic research was conducted in two companies which work with software development using agile methodologies. The findings indicated several practices which were enacted by the two organizations, of which many of them appeared to be interrelated. The “knowing” which was constituted in these practices were categorized as “knowing how to develop competencies/ capabilities” and “knowing how to coordinate effort”.

    The practices found in the study were similar to some of the practices commonly cited in current knowledge management literature. Notwithstanding this, new knowledge was not created from the conversion of tacit to explicit knowledge and vice versa. On the contrary, “knowing how” was generated and sustained through the ongoing actions and everyday practices of the individuals in the agile teams.

    Application Outsourcing Governance Model: Critical components of a Successful Application Outsourcing Governance Framework2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Emerging technologies have changed the environment of global competition; many IT-firms are adapting new trends of offshore software development to attain latest and low costs services. This research report is aimed to fill the literature void on application outsourcing governance and emphasize on the components critical for a successful application outsourcing governance model. The research is conducted on a service-buyer IT-firm which forwards software development assignments to its vendors locally as well as globally. Research employs qualitative method where social constructivist philosophical worldview is used to gain practical understanding of participants’ viewpoints on the research topic; research uses inductive approach which is intended at theory building. Three types of interview methods are used for data collection; analytical process of Grounded Theory is used to analyze the data systemically. GT coding technique is used to code collected data into different concepts by constant comparison and by asking questions; similar concepts are gathered under different categories. One core category and seven key categories are emerged from the data; these categories represent the key components of application outsourcing governance model. Finally, these components integrate in order to form application outsourcing governance framework for successful deliveries of application outsourcing projects.

    Expanding Business from Products to Digital Services: Value Dimensions of Digital Services Enabled by Embedded Technology2014In: Proceedings of the 8th Mediterranean Conference on Information Systems / [ed] Mola, L., Carugati, A., Kokkinaki, A., Pouloudi, N., 2014, p. Paper 12-Conference paper (Refereed)
    Abstract [en]

    Manufacturing firms are now embedding digital technology into products with an aim to offer digital services to their customers. Digital services create opportunities for firms to add new value dimensions to their businesses as firms now can expand their businesses from tangible products to digital services. Existing research explains three value dimensions. ‘Value-in-exchange’ is traditionally followed by manufacturing firms where they determine monetary value for their products and exchange the value with customers. Recent research argues that ‘value-in-exchange’ is not customer centric and therefore to gain customer value, ‘value-in-use’ and ‘value-in-cocreation’ are necessary. With growing utilization of embedded digital technology in products, new digital services are rendered and new value dimensions are emanating. Existing research informs little about the value dimensions of digital services that result from the combination of digital technology and tangible products. Therefore, in this research, we seek answer to the question, ‘What are the value dimensions of digital services that are enabled by embedded digital technology in tangible products?’ A qualitative study has been conducted to investigate Remote Diagnostics Services (RDS) for vehicles. Along with the three known value dimensions, that is, value-in-exchange, value-in-use and value-incocreation, this research contributes to knowledge by showing two new value dimensions: ‘value-in-connectivity’ and ‘value-in-architecture’.

    Service Logic in Digitalized Product Platforms: A Study of Digital Service Innovation in the Vehicle Industry2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The digitalization of products has become an important driver for service innovation in manufacturing firms. The embedding of digital technology in previously non-digital products creates digitalized product platforms that enable digital service innovation. Digital service innovation offers new business opportunities for manufacturing industries, as well as challenges established premises for value creation.  While digital service innovation can be found in many manufacturing industries, this thesis studies service logic in digitalized product platforms in the vehicle industry.

    Existing Information Systems (IS) literature presents challenges in digital service innovation relating to value, architecture, and generativity. The design of the architecture of digitalized product platforms requires the identification and combination of digital and non-digital assets. Understanding the architectural aspects is useful in digital service innovation. Moreover, with growing instances of generative digital technologies, it is challenging to develop strategies to leverage generativity for service design in digitalized product platforms. While digital technologies are embedded in products, the role of technology-embeddedness in value creation of digital services is relatively unexplored. Drawing on these challenges, this thesis describes and conceptualizes the underlying premises brought by the architecture and generativity to the value creation of services in digitalized product platforms. The research question addressed in this thesis is: What are the underlying premises for services in digitalized product platforms?

    To address the question, an interpretive qualitative research approach was adopted in a collaborative research project concerning services enabled by digitalization of vehicles. Drawing on digital innovation and service literature, this thesis presents a theoretical perspective on the role of the architecture and generativity of digitalized product platforms for value creation of digital services. This perspective is conceptualized as underlying premises for this specific class of services. The premises frame the service logic in digitalized product platforms and provide a ground for understanding services in digitalized product platforms in relation to value dimensions, architecture and generativity. The premises are based on five concepts: value-in-architecture, value-in-connectivity, fundamental asset for value creation, mutual dependence of modular and layered modular assets, and re-evaluation of value propositions. The proposed premises offer a basis for understanding value creation of this class of services, and guidance for manufacturing firms designing digitalized product platforms.

    Challenges and Opportunities Related to Remote Diagnostics: An IT-based Resource Perspective2013In: International Journal of Information Communication Technologies and Human Development, ISSN 1935-5661, E-ISSN 1935-567X, Vol. 5, no 3, p. 80-96Article in journal (Refereed)
    Abstract [en]

    Remote diagnostics is expanding the business scope of vehicle manufacturers, ranging from products to services. In this paper, we focus on investigating the business challenges and opportunities related to the remote diagnostics of vehicles from an IT-based resource perspective. Remote diagnostics involves technology, human skills and intangibles. IT-based resources consist of physical IT infrastructure, human IT skills and IT-enabled intangibles. In this study, we find that remote diagnostics not only faces challenges in these three categories of IT-based resource, but also creates opportunities. One contribution of this paper is to provide an overview of the challenges and opportunities for business related to the technology. The paper also makes a contribution to information systems by shedding light on the discussion of digital infrastructure. It also highlights the application of IT-based resource perspective to find out the business challenges and opportunities of an emerging technology like remote diagnostics.

    Abstract [en]

    In this paper, we characterize the architecture of digital services that are enabled by embedded technology. Digitalization with embedded technology in physical products has become a common phenomenon. In spite of growing instance of such digitalization, little is known about the architectural characteristics of digital services enabled by embedded technology. Based on a research on vehicular remote diagnostics services, we characterize the architecture of such digital services. Following the framework on layered modular architecture continuum, our findings provide the following architectural characteristics: i) the architecture of the digital services spans along the layered modular architecture continuum, ii) the application program of the digital services is simultaneously de-coupled and partly coupled with the embedded devices, iii) there exist layers within layer of the digital services, iv) application program layer of the digital services is a closed innovation platform. © 2014 IEEE

    Systems Thinking Benefits in Supply Change Management: An illustration of the viable systems model in a supply chain2009In: International Journal of Intelligent Systems Technologies and Applications, ISSN 1740-8865, E-ISSN 1740-8873, Vol. 6, no 3/4, p. 227-248Article in journal (Refereed)
    Abstract [en]

    Existing product development models are solely an organisational matter. They do not take into consideration the whole Supply chain (SC) and its different actors. In this article, we investigate how Supply Chain Management and Viable System Model (VSM) can support and create an effective use of information in product development and hence identify critical linkages in the SC. The aim is to introduce VSM as a framework that enables an analysis of companies’ SCs and visualise vital inter-organisational relationships that should be integrated in product development.

    The Missing Chart and Compass to Open Governance: Research in progress2018In: Presented at SWEG 2018. The 15th Scandinavian Workshop on E-Government / [ed] Normann Andersen, K., Zinner Henriksen, H., Copenhagen, 2018Conference paper (Refereed)
    Abstract [en]

    Today’s society is facing a number of pervasive societal trends such as increased globalization, accelerating urbanisation, a growing knowledge society, stronger individualization, as well as increased variety and pluralism (SOU 2016:89). These phenomena are driven and enabled by the data driven digitalization and new technologies, and taken together they indicate that a digital transformation is ongoing. In the end the digital transformation of the society will influence all, from individuals to nations and globally. It is plausible to say that the digital transformation is unescapable and Janowski (2015) claims that it is clear that governments and policymakers must pay attention to and be ready to govern the digital space since many of the cultural, political, economical and other human activities now occur in the digital space. Sweden aims high, in 2012 the Swedish government appointed Digitaliseringskommissionen the mission to realize the IT policy goal; to become supreme in making use of all the possibilities that digitalization brings along. Digitaliseringskommissionen states that Sweden is strong in areas such as infrastructure, human capital and use of the Internet, and have many ICT specialists, but Sweden is weak when it comes to digitalizing the public sphere; there is lack of co-ordination of administrations (finding common solutions) and open data (SOU 2016:89).

    The PHP programmer`s guide to secure code2005Student thesis
    Abstract [en]

    Abstract

    Security threats against computer systems are a big problem today which also includes PHP made applications. The report is focused on protection with the help of code and not how you protect a web server. Its purpose is not to educate the readers of the thesis how to make a PHP application, the purpose is how to program a safer PHP application. The thesis contains information about common security threats against PHP scripts. It contains in most cases examples of what an attack can look like and how a protection for that example can be achieved. We have tested all code examples if they work by installing our own server with the configurations according to the delimitations of the thesis and putting up small PHP applications, which we have attacked and then protected. The contents and result of this thesis can benefit developers that use PHP as a programming language for creating web applications, by giving them information about common threats and protection.

    Processförbättring med hjälp av TMMi-Modellen: Utvärdering av en testprocess på ett medelstort företag2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Storleken och komplexiteten på dagens system och applikationer ökar. Detta leder till att kraven på system och applikationer ökar också eftersom kunderna kräver av dagens system full funktionalitet inom olika typer av distribuerade miljöer. Kunder är inte bara intresserade av funktionerna i systemen och applikationerna, de förväntar sig också att systemet skall vara av god kvalitet. Av dessa skäl är det mycket viktigt att testa system och applikationer för att säkerställa att de uppfyller kundernas förväntningar. Däremot är det inte bara själva mjukvarans kvalitets frågor som organisationer behöver ha i åtanke, en lika viktig del är själva testprocessens kvalitet. För att öka testprocessens kvalitet  krävs det en utvärdering av processen. Utvärderingen identifierar processens styrkor, svagheter och möjligheter.

    I detta examensarbete har vi utvärderat tesprocessen på ett utvecklingsföretag. Utvärderingen har baserats på anvisningar och rekommendationer från TMMi-modellen, Test Maturity Model Integrated. Vi hade som mål att lyfta fram förbättringsförslag till företagets testprocess. Efter utvärderingen kom vi fram till vilken mognadsnivå verksamheten utifrån TMMi-modellen samt en mängd förbättringsförslag för att höja mognadsnivån på testprocessen.

    Användaracceptans vid systemimplementering.2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    User acceptance is an important part of all system development projects and is also a very easily influenced variable for a successful implementation. That is why it is important to have an overview of those factors that could influence the user acceptance negatively, one of those factors being delay. This thesis highlights the cohesion between a delayed project and its influence over the user acceptance. By letting a study group answer a survey formed by the Technology Acceptance Model, I have gathered the generalized opinion of the group. The results show that delay as a variable does not influence the user acceptance of this case study.

    Metod för systemutveckling till småföretag2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    System development methods have existed to develop systems and

    programs since the waterfall model was introduced when IT was called

    data processing. There have been a number of methods since that day,

    some of them are still used. A common denominator for the most software

    development methods are that they where all developed to support software

    engineering to complex system in large organizations. Within the Swedish

    society there were over 890 000 small businesses (0-49 employed) in year

    2005 according to statistiska centralbyrån. It’s no secret that the small

    businesses are very important to Sweden. To assure survival when the

    competition gets harder the small businesses must the entire time look over

    there business processes. Sometimes this means that they need new custom

    made IT systems. This thesis will examine possible system development

    methods for small Swedish businesses and adopt one method to fit small

    business software development.
