    WCET and mixed-criticality: What does confidence in WCET estimations depend upon?2015In: OpenAccess Series in Informatics, 2015, 65-74 p.Conference paper (Refereed)
    Abstract [en]

    Mixed-criticality systems integrate components of different criticality. Different criticality levels require different levels of confidence in the correct behavior of a component. One aspect of correctness is timing. Confidence in worst-case execution time (WCET) estimates depends on the process by which they have been obtained. A somewhat naive view is that static WCET analyses determines safe bounds in which we can have absolute confidence, while measurement-based approaches are inherently unreliable. In this paper, we refine this view by exploring sources of doubt in the correctness of both static and measurement-based WCET analysis.

    Template-driven Documentation of Best Practices2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Knowledge Management has become a key instrument for identifying, creating and sharing organizational knowledge assets. An attractive means for sharing knowledge is Best Practices (BPs), which are proven as well as efficient and effective solutions to recurring problems. BPs can offer significant benefits, including improved performance, reduced re-work and cost savings. However, it is challenging to share and use BP Documents (BPDs) in organizations, which is the overall problem addressed in this thesis. More precisely, the thesis focuses on two sub-problems: 1) The difficulty of finding and selecting appropriate BPs in large collections of BPs impedes the use of BPs, and 2) The low quality of BPDs impedes the use of BPs. Related to these problems, the thesis addresses two sub-goals. The first one is to design a BP Annotation Template for supporting the identification and selection of BPs in BP repositories. The template can be used for organizing and indexing the contents of BPDs independent of domain. The second sub-goal is to design a BP Document Template for supporting the creation, use and evaluation of BP documentation. The BP Document Template offers a structure for describing BPs in a detailed and systematic way.

     

    The research methodology applied is design science, which is the scientific study and creation of artifacts as they are developed and used by people with the goal of solving practical problems. The first artifact, the BP Annotation Template, has been designed and developed based on a literature study and evaluated using expert interviews. The second artifact, the BP Document Template, has been designed and developed based on a literature study using grounded theory as well as on interviews with KM experts. The BP Document Template has been evaluated using expert interviews and demonstrated by being applied in three real-life cases. By basing the two artifacts on literature studies, the two artifacts consolidate, integrate and extend previous work on BP documentation.

     

    The evaluations indicate that the BP Annotation Template provides a strong foundation for identifying and selecting BPs, independent of domain, and that the BP Document Template can support the structuring of BP documents so that they become complete, uniform and easy-to-use. An identified drawback of the two artifacts is the need for extensive resources for implementing and applying them since they may be complex and time-consuming to use. The artifacts are expected to support BP designers as well as BP managers and BP users.

    A synthesized classification system for best practices2014In: Vine: The Journal of Information and Knowledge Management Systems, ISSN 0305-5728, E-ISSN 1474-1032, Vol. 44, no 2, 249-266 p.Article in journal (Refereed)
    Abstract [en]

    Purpose – The aim of the study is to propose a classification system for best practices (BPs). The system is intended for organizations that are interested in indexing, storing and retrieving large quantities of BPs. Design/methodology/approach – An extensive literature survey to identify relevant articles by searching e-resource databases, including international journals and conferences related to the use of BP was conducted. A content analysis was conducted on selected articles to identify how BPs can be indexed. Findings – The authors are concerned with identifying what BP frameworks exist in literature and how BPs can be classified based on the features of these BP frameworks. Subsequently, they reviewed the identified frameworks within the literature and built a BP classification system. This classification system consists of a number of features, referred to as variables, where each variable is associated with a set of possible values. Originality/value – The proposed BP classification system is intended to provide a guideline for recognizing general characteristics for all BPs in any domain or organization to aid stakeholders in classifying BPs.

    Evaluation of a Classification System for Best Practices2015In: Proceedings of the 48th Annual Hawaii International Conference on System Sciences: 5–8 January 2015 Kauai, Hawaii / [ed] Tung X. Bui, Ralph H. Sprague, Jr., IEEE Computer Society, 2015, 3702-3711 p.Conference paper (Refereed)
    Abstract [en]

    The practical problem addressed in this paper is that it can be problematic to find appropriate best practices (BPs) in a large collection of BPs, covering many different domains, within an organizational database. Our goal was to propose a classification system of BP documentation to facilitate effective use and retrieval of BPs documents in such a large collection of BPs, independent of any domains. We have designed such a domain independent classification system and evaluated it with practitioners and academic experts. We found that all the BP characteristics and labeled values in the proposed classification system were recognized and applied by practitioners as well as academic experts. However, it turned out that some of the characteristics were particularly useful. These characteristics were: implementation area, level of formalization, completeness of description, Balanced Scorecard perspectives, and management process.

    An empirical investigation of how best practices can be created: A case study from Saudi Arabia2012In: Advances in Business-Related Scientific Research Conference (ABSRC): Proceedings OLBIA 2012, 2012Conference paper (Refereed)
    Abstract [en]

    The paper investigates the identifying of best practices in Saudi Arabia. We adopted an established theoretical framework that is used as a basis for developing questions for the study. In Saudi Arabia, there are efforts for sharing best practices that can be viewed a positive step forward. Interviews were held with selected informants at a number of large companies. The results from the interviews that analyzed and the analysis showed that organizations are not acquainted with the formal BP framework. They linked identification of BP to documented practices, to communities of knowledge, or to specific publications. We suggested that a BP team can obtain some direction toward evaluating and sharing candidate best practice. Hence, we propose that a contribution of best practices from an online network of best practices is a recommended most useful approach for supporting the collaboration between promoting the sharing of knowledge between business enterprises.

    Creating Best Practices in Saudi Arabia2013In: Advances in Business Related Scientific Research Journal (ABSRJ), ISSN 1855-931X, Vol. 4, no 2, 113-125 p.Article in journal (Refereed)
    Abstract [en]

    This paper investigates identification of best practices (BPs) in Saudi Arabia. We adopted an established theoretical framework as a basis for developing questions and conducting the study. Interviews were held with selected informants at a number of large organizations. The analysis of interview results showed that organizations are not acquainted with the formal BP framework. They linked identification of BP to documented practices, to communities of knowledge, or to specific publications. However, Saudi Arabia's attempts at sharing BPs can be viewed as a positive step forward. We suggested that a BP team is needed to obtain some direction toward evaluating and sharing BP. Our study revealed the need for having a clear working template for creation and documentation procedures of BP. Also, we suggested that a contribution from an online network of BPs is a recommended, and most useful, approach for supporting the collaboration between business enterprises in terms of sharing BP.

    Quality Measures for Documentation of Best Practices2014In: 2014 47th Hawaii International Conference on System Sciences (HICSS) / [ed] Sprague, R. H., IEEE Computer Society, 2014, 3410-3419 p.Conference paper (Refereed)
    Abstract [en]

    Research has identified a set of factors that may impact the success of implementing a best practice (BP). One such factor is to properly document the BP. Without a high quality documentation of BPs it might be difficult to understand and implement BPs within an organization. Therefore, we propose a set of quality measures (QMs) for BPs categorized in the form of a template, aimed at supporting the quality enhancement of documented BPs. The proposed template can be applied during the design of BPs in order to support the construction of high quality documentation of BPs, but can also be applied during the evaluation of already designed BPs. A tentative template was designed based on both a literature review and our own experiences in the area of Knowledge Management. We evaluated the tentative template by presenting it to practitioners and academic experts in the area of BP. Based on their evaluation we refined the model in an iterative approach, adjusting the QMs after each practitioners’ and academic experts’ input until we reached a final template. In this paper, we present the final template of QMs, and demonstrate its feasibility by applying it to existing BPs from a real- life organization. The research methodology applied was design science research.

    Applying a Template for Best Practice Documentation2015Conference paper (Refereed)
    Abstract [en]

    Knowledge Management has become a key instrument for creating, identifying and sharing knowledge assets inorganizations. Best Practice (BP) is a useful means for organizations to improve knowledge sharing. However, lowquality of BP documentations can hinder a successful implementation of BPs, since practitioners may not be able tocorrectly and efficiently use them, or even trust them. In this paper, a BP Document Template (BPDT) for high qualitydocumentation is presented. The final BPDT is a result of the combination of two templates, the first one created based oninterviews with knowledge management experts and the second one based on a literature review using grounded theory.The final BPDT has been applied in three real-life organizations for demonstrating its benefits, drawbacks, completeness,ease of use, and whether it also supports both the design of BPs and the evaluation of already designed BPs. Thedemonstration showed promising results but also some drawbacks. The identified drawbacks can be used as input forfuture research.

    Template-driven Best Practice Documentation2015In: Journal of Information and Knowledge Management, ISSN 0219-6492Article in journal (Refereed)
    Abstract [en]

    Knowledge Management has become a key instrument for identifying, creating and sharing organizational knowledge assets. An attractive means for sharing knowledge is Best Practices (BPs), which are proven as well as efficient and effective solutions to recurring problems. BPs can offer significant benefits, including improved performance, reduced re-work and cost savings. However, the implementation of BPs raises several challenges, one of which is that the low quality of BP documentation can impede the use of BPs. One way to address this challenge is by supporting designers in structuring BP documents so that they become complete, uniform and easy-to-use. This support can take the form of a BP Document Template that prescribes the structure of BP documents by defining relevant attributes for describing BPs. This paper proposes a comprehensive and practical BP Document Template for supporting the creation, use and evaluation of BP documents. The design of this template is an example of design science research including requirements elicitation, artifact development, demonstration, and evaluation. The development is based on a combination of expert interviews and a literature study using Grounded Theory, while the demonstration applies the proposed template in three real-life cases, and the evaluation is based on expert interviews. The proposed BP Document Template consolidates, integrates and extends previous work on BP documentation. It thereby offers an effective tool for BP designers, managers, and users that can support them in the design, evaluation and application of BPs.

    Verifying the Usefulness of a Classification System of Best Practices2013In: Proceedings of the International Conference on Knowledge Discovery and Information Retrieval and the International Conference on Knowledge Management and Information Sharing / [ed] Ana Fred ; Kecheng Liu ; Joaquim Filipe, SciTePress, 2013, 405-412 p.Conference paper (Refereed)
    Abstract [en]

    Transfer of best practices (BPs) within an organization can significantly enhance knowledge transfer. However, in order to manage a large number of BPs within an organization, there need to be some structure for how to classify the BPs. In this paper, we present a best practice (BP) system for classifying BPs and evaluate how easy the system is to use for classifying best practices. The research approach applied was design science, which is characterized by designing an artifact in this case a BP classification system, and evaluating it. The evaluation was carried out by asking Master’s students to collect two BPs from organizations and subsequently having them classify the BPs according to the BP classification system. They were also asked to motivate their choices during their act of classification. The results of the evaluation are promising: the BP system could be used for classifying BPs since students utilized all possible values of the BP system during the act of classification. Also, it was easy for the students to justify their classifications, which might be interpreted as an ease of using the BP classification system.

    On Aircraft Conceptual Design: A Framework for Knowledge Based Engineering and Design Optimization2008Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents a design framework where analytical tools are linked together and operated from an efficient system level interface. The application field is aircraft conceptual design. Particular attention has been paid to CAD system integration and design optimization.

    Aircraft design is an inherently multidisciplinary process. The goal is to search for the design that, in the best of possible ways, fulfills the requirements. It is therefore desirable to be able to effectively investigate and analyze solutions from a variety of points of view, weighting together the results and gathering a general figure of merit. At the same time, increasing competition on a global market forces to shorten the design process and to reduce costs. Thus a system that allows a tight and efficient integration of different disciplines and improving data flow and storage plays a key role.

    Integrating a CAD system to the framework is of central relevance. The geometrical model includes most of the information; specific data, required to carry out particular analysis, can be extracted from it. This is possible adopting parametric associative models that are controlled from a spreadsheet user interface. Strategies for building CAD models with a very high degree of flexibility are presented. Not only the external shape can be changed, but also the internal structure can be completely modified. Structural elements can be added or removed, and their position and shaping changed.

    In this work the design of an Unmanned Aerial Vehicle is used as test case for comparing three different optimization algorithms. The presented framework is also used for automatically design Micro Aerial Vehicles, starting from a short list of requirements and ending with a physical prototype produced by a rapid prototyping machine.

    Virtual Teams - Support for Technical Communication2013In: Journal of Organizational Transformation and Social Change, ISSN 1477-9633, Vol. 10, no 1, 87-103 p.Article in journal (Refereed)
    Abstract [en]

    To work together in virtual teams has increasingly become a natural change

    in how organizations work. Due to demands from the environment,

    organizations have had to transform from traditional ways of working to

    becoming more flexible and adaptive. The aim of this article is to identify

    obstacles, problems, and presumptions in order to enable the virtual team to

    be successful. A project — The TIC-project — is described, and results from

    a study concerning collaboration and networking among companies within

    Technical Communication are presented. Results show that, to a great

    extent, experiences from networking are lacking. Furthermore, trust must be

    embedded in the teams, meaning that personal meetings must precede

    virtual meetings. Most interviewees declared a wish to collaborate despite

    being competitors. Finally, questions and topics for further research are

    presented.

    Abstract [en]

    To commemorate the tenth anniversary of alt.chi, two of this year's alt.chi chairs, Ames and Lindtner, will moderate a panel with chairs from previous years to reflect on the legacy of alt.chi in the broader CHI community and discuss where the track should be headed in the future. We intend the panel to be highly interactive, incorporating the audience in discussion and debate. We encourage those with thoughts on alt.chi as well as those who want to learn more about the track, to attend and actively participate. The following questions will start the discussion: 1. What is the role of alt.chi in the CHI community, and how has it shifted across the last decade? 2. What alt.chi research papers or themes have been particularly influential or provocative? 3. What is the state of critical discourse and reflection in alt.chi? Has alt.chi been a successful venue for such work? Should it be? 4. Where is alt.chi headed, what is missing, and how could it change?

    Facebook Blocket with Unsupervised Learning2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    The Internet has become a valuable channel for both business-to- consumer and business-to-business e-commerce. It has changed the way for many companies to manage the business. Every day, more and more companies are making their presence on Internet. Web sites are launched for online shopping as web shops or on-line stores are a popular means of goods distribution. The number of items sold through the internet has sprung up significantly in the past few years. Moreover, it has become a choice for customers to do shopping at their ease. Thus, the aim of this thesis is to design and implement a consumer to consumer application for Facebook, which is one of the largest social networking website. The application allows Facebook users to use their regular profile (on Facebook) to buy and sell goods or services through Facebook. As we already mentioned, there are many web shops such as eBay, Amazon, and applications like blocket on Facebook. However, none of them is directly interacting with the Facebook users, and all of them are using their own platform. Users may use the web shop link from their Facebook profile and will be redirected to web shop. On the other hand, most of the applications in Facebook use notification method to introduce themselves or they push their application on the Facebook pages. This application provides an opportunity to Facebook users to interact directly with other users and use the Facebook platform as a selling/buying point. The application is developed by using a modular approach. Initially a Python web framework, i.e., Django is used and association rule learning is applied for the classification of users’ advertisments. Apriori algorithm generates the rules, which are stored as separate text file. The rule file is further used to classify advertisements and is updated regularly.

    A Comprehensive Evaluation of Conversion Approaches for Different Function Points2011Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Context: Software cost and effort estimation are important activities for planning and estimation of software projects. One major player for cost and effort estimation is functional size of software which can be measured in variety of methods. Having several methods for measuring one entity, converting outputs of these methods becomes important. Objectives: In this study we investigate different techniques that have been proposed for conversion between different Functional Size Measurement (FSM) techniques. We addressed conceptual similarities and differences between methods, empirical approaches proposed for conversion, evaluation of the proposed approaches and improvement opportunities that are available for current approaches. Finally, we proposed a new conversion model based on accumulated data. Methods: We conducted a systematic literature review for investigating the similarities and differences between FSM methods and proposed approaches for conversion. We also identified some improvement opportunities for the current conversion approaches. Sources for articles were IEEE Xplore, Engineering Village, Science Direct, ISI, and Scopus. We also performed snowball sampling to decrease chance of missing any relevant papers. We also evaluated the existing models for conversion after merging the data from publicly available datasets. By bringing suggestions for improvement, we developed a new model and then validated it. Results: Conceptual similarities and differences between methods are presented along with all methods and models that exist for conversion between different FSM methods. We also came with three major contributions for existing empirical methods; for one existing method (piecewise linear regression) we used a systematic and rigorous way of finding discontinuity point. We also evaluated several existing models to test their reliability based on a merged dataset, and finally we accumulated all data from literature in order to find the nature of relation between IFPUG and COSMIC using LOESS regression technique. Conclusions: We concluded that many concepts used by different FSM methods are common which enable conversion. In addition statistical results show that the proposed approach to enhance piecewise linear regression model slightly increases model’s test results. Even this small improvement can affect projects’ cost largely. Results of evaluation of models show that it is not possible to say which method can predict unseen data better than others and it depends on the concerns of practitioner that which model should be used. And finally accumulated data confirms that empirical relation between IFPUG and COSMIC is not linear and can be presented by two separate lines better than other models. Also we noted that unlike COSMIC manual’s claim that discontinuity point should be around 200 FP, in merged dataset discontinuity point is around 300 to 400. Finally we proposed a new conversion approach using systematic approach and piecewise linear regression. By testing on new data, this model shows improvement in MMRE and Pred(25).

    Samband mellan motivationsfaktorer för UGC: Vad motiverar en användare att skapa innehåll på internet?2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    User Generated Content (UGC) is becoming increasingly common on the web and many of the most frequently visited websites on the Internet is largely based on content created by its users. Every day 120,000 articles gets edited on Wikipedia by its devoted users who spend an average of eight hours a week on creating new or edit existing material. To motivate users to contribute with content is becoming increasingly important. This requires an increased understanding of what motivates users to contribute. 

    In this paper we study the motivational factors that motivates users to contribute with UGC and if there is any correlation between these motivational factors. A literature review of previous research in the field of UGC is performed and results in 15 motivational factors categorized into four categories. These are presented in a matrix that structures the motivation factors in the different categories. The matrix of the 15 motivational factors are the theoretical foundation for a quantitative survey designed to see to what extent users are motivated by different motivational factors for the creation of UGC. Through the survey we establish an understanding to what extent different motivational factors motivate the participiants of the study to create UGC. The results from the survey are then used to study the relationships between motivational factors. This leads to a correlation table that presents all the significant relationships between factors and a motivation matrix that can serve as a basis for understanding and discuss the motivators for the UGC and its categorizations. Our results may help developers to support multiple motivational factors in services based on UGC. The motivation matrix and the results presented may also be the basis for future research.

    In order to identify needed skills and competencies for privacy and security, we propose a systematic process that maps privacy and security threats to related controls that are required to prevent, detect or remove such threats. This work suggests how to apply the process, while discussing how games and simulations can be used both to develop the desired behavior and to monitor the current competency level.

    Helping Out Refugees: the Way Forward Stakeholders' Activities for Newcomers in Trollhättan2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study used the qualitative research approach to investigate stakeholders' activities, stakeholders' opinions on technology, stakeholders' opinions on newcomers and problems of stakeholders in Trollhättan. Interest was on provided activities of the stakeholders'. With the actor network theory (ANT) framework, the study addressed the problem of newcomers to know about stakeholders' activities in Trollhättan. Semi structured in-depth interviews were conducted on seven stakeholders in Trollhättan municipality. A private company, Trollhättan Municipality Employment Office, the Red Cross, a university and three non-profit organizations. Data were analyzed based on summative content analyses. The study revealed that stakeholders arrange varied types of initiatives but it was hard for refugees that were placed in Trollhättan, especially newly arrived in Trollhättan to get access to the initiatives. The study concluded that reaching out to newly arrived newcomers is a major problem for stakeholders in Trollhättan.

    An investigation of the use of software development environments in the industry2004Independent thesis Basic level (professional degree)Student thesis
    Abstract [en]

    Software engineering tools are being used in the industry in order to improve the productivity and the quality of the software development process. The properties of those tools are being perceived to be unsatisfactory. For example, researchers have found that some problems are due to deficient integration among the tools. Furthermore, a continuing problem is that there is a gap between the IT education and real demand of tool-skills form IT industry. Consequently, knowledge is needed of the properties of software development tools as well an understanding of demanded tool-skill from the industry.

    The purpose of this study is to survey commercial software development environment (SDEs) that are used today in professional software engineering and discuss their advantages adn disadvantages. A secondary goal of the study is to identify the actual requirements from the industry on the IT-education.

    A questionnaire was sent out to 90 software developers and IT managers of 30 IT companies in Sweden. The results of the survey show that IT companies, for most part, use SDEs from commercial software vendors. Respondents report that common problems of the SDEs are the following: bad integration among the tools, problems to trace software artifacts in the different phases of the programming cycle, and deficient support for version control and system configuration. Furthermore, some tools are difficult to use which results in a time-consuming development process.

    We conclude that future software development environments need to provide better support for integration, automation, and configuration management. Regarding the required tool-skills, we believe that the IT education would gain from including commercial tools that cover the whole software product lifecycle in the curriculum.

    Building trust and confidence through sustainable information systems research: Towards a common future2015In: INFuture 2015: e-Institutions - Openness, Accessibility, and Preservation / [ed] Karen Anderson, Luciana Duranti, Rafal Jaworski, Hrvoje Stancic, Sanja Seljan, Vladimir Mateljan, Zagreb: Department of Information and Communication Sciences, Faculty of Humanities and Social Sciences, University of Zagreb , 2015, 9-18 p.Conference paper (Other academic)
    Abstract [en]

    The Information Systems research group at Mid Sweden University is the result of four separate groups, spread across three disciplines, artificially thrown together because we didn’t seem to fit into other developed research groups. What we were seen to have in common was ‘information’. The disciplines are: Archives and Information Science, Business Management and Organization, and Informatics.

    Shortly after this uncertain start, the University launched a demanding internal process for Assessment of Research and Coproduction (ARC13) over the previous five years. We didn’t have that much past together, so we set out to build ourselves a future, exploring our common interests as we gathered data for the evaluation. We pooled our research, hired a facilitator to help with a SWOT analysis, built trust within the group and achieved a remarkably good report from the external assessors. Participation in the multidisciplinary InterPARES Trust in Digital Records in an Increasingly Networked World Project has been an inspiring factor in the Archives and Information Science contribution to our new collaboration. Our Information Systems research group now focuses on five research challenges: Information value, quality, accessibility, sustainability and trustworthiness.  Now we are having fun exploring the possibilities, confident that our InfoSys research group has its own sustainable future.

    Recordkeeping definitions in legislation:: a conceptual step towards smoothing business interaction in the digitally networked world?2013In: Archives: the Future: Australian Society of Archivists 2013 Conference / [ed] Shapley, Maggie, Canberra, 2013Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    Legislation is important to recordkeeping strategies and requirements, since it determines which records are needed for legally legitimate actions. Yet the concepts of a document, a record, a case, a transaction, etc., are frequently defined differently in various laws even within national boundaries and are urgently in need of harmonization to minimize complications and barriers to e-business transactions.

    Every country has its own legislation system which has been adjusted over time in correlation to national context and its surrounding society (Duranti, 1989-1990, p. 5). Duranti and Goh (2012) provided sound arguments as to why it is important to ensure national archival legislation keeps pace with our digitally networked society with its increasingly blurred borders. In addition to their own national law, members of the European Union (EU) are obliged to follow EU-legislation requirements. There are three types of EU legislation: regulations, directives and decisions. A regulation is applicable in all EU countries. Directives are general rules. A decision is a stipulation of issues of concern for specifically mentioned persons or organizations (European Commission, 2013).  Recommendations and statements are not binding, but may, for example, be used by the EU as support in interpretation of EU-legislation (Sveriges Riksdag, 2013). Hence, within public organizations, there is a close relation between records, recordkeeping processes, legislation and accountability.  Yet research in Sweden has shown that 24/7 e-service web-interfaces serving e-government strategies and ambitions are sometimes developed without consulting recordkeeping professionals, in ignorance of legal requirements for capture of records and that preservation issues are rarely considered when acquiring new digital systems (Kallberg, Svärd and Sundberg, 2010). Several other European studies also identify a lack of recordkeeping awareness within public organizations (Barata, 2004; Valtonen, 2007; Shepherd, Stevenson, & Flinn, 2009; Riksarkivet, 2010). However, there is currently a strong European political ambition to implement eGovernment services, which aims to promote cross-border business development. On the other hand, this challenges archival thinking to meet business, technological and legal requirements stipulated for each country. Varying legal definitions used can cause major problems for transactions both within a country and across national borders, even in something as seemingly simple as exchanging e-invoices. This paper will discuss an approach to identifying a way forward for harmonizing legislation that contains recordkeeping requirements across the EU.

    • Identifying the range of / types of laws within countries and EU that define a record
    • Using the ICA multilingual terminology database, to check and add to definitions already found there
    • Checking against definitions found in international standards.

    Research towards harmonizing these crucial definitions will be very challenging, given linguistic and cultural differences but the ICA multilingual terminology database is a potential vehicle for checking existing usage, adding to the definitions and quotations from legalislation and the literature already found there and adding new terms. The foundation version of the ICA-funded Terminology Database, developed as an ICA Section for Archival Educators’ project led and hosted by the University of British Columbia, contains definitions with examples of usage for an initial 300 archival terms across 16 languages. It is planned for public release in the first half of 2013.

    Mature Public e-Services Without Mature Recordkeeping – An Impossibility?2010In: iRMA Information and Records Management Annual, ISSN 1836-3202, 71-82 p.Article in journal (Refereed)
    Abstract [en]

    The Swedish Government has established the eGovernment Delegation agency to identify and support excellence in e-government implementation strategies. This agency has commenced working with the National Archives, to ensure that archival requirements are addressed when developing new e-services. However, the prevailing view of archives is a traditional curatorial approach, which focuses on capturing the end product once actions have been completed. In the digital environment, the prevailing archival practice frameworks are not adequate to the task of capturing the full digital context and process that is essential for a complete record. Previously, when paper records were aggregated on a physical file, the full record of processes was more likely to be captured and managed for the long term.

    Results from two empirical case studies will be used to present and illustrate the risks and problems generated by an approach where the records are not identified and captured until late in the business process. In this paper the term post hoc approach to records capture is used to describe the method whereby an attempt is made to capture records, including the necessary metadata, after they are created, without prior planning or system design. One of the Swedish eGovernment Delegation’s aims is to motivate public agencies to reach level four on Layne and Lee’s e-government maturity model, that is, full integration of interaction between agencies and citizens. However, the model does not incorporate any recordkeeping requirements in its maturity benchmarks. It is clear these kinds of e-services are so complex that late intervention by archivists will not be adequate for needed recordkeeping support and long-term preservation. So it is essential that guidance on archival preservation of integrated e-services is made available as soon as possible, particularly as current trends in government indicate that e-services will be outsourced to private providers.

    Strategies are proposed for including recordkeeping re- quirements in e-service models. Advantageously, this can be done using existing benchmarking tools such as GARP, ISO 15489, ISO 30301 and the ICA Principles and Functional Requirements for Records In Electronic Office Environments.

    Open data through the archive: A new role for archivists2014Conference paper (Other academic)
    Abstract [en]

    The role of the archivist in exploiting and accessing open data as public records in an open government environment is explored.  The possible role, responsibilities and mandate of an archivist in this new public sector context are examined. Necessary knowledge, skills and competence are identified. 

    Content:

    Expectations of a more proactive release of public records and technical developments that support new ways of publishing and reusing digital information, for example as open data on the internet, create new challenges and change the way public records are managed and made accessible to citizens, which will also involve new professions in the management of records. Fundamentally this raises questions of how, in this new management environment, the trustworthiness of the records could be maintained and how the archives and records management profession could contribute to this, related to other professionals involved in these processes.

    In Sweden there is a long tradition of openness and citizens´ right to access public records. But with the implementation of e-government follows a new perception of what openness means and “open government” is a concept that seems to go further and be more proactive. A part of this study will be to analyze and define what is meant by ‘open government’ and ‘open data’ as they are used in Sweden, i.e. how ‘open data’ differs from ‘public records’ for example. In Sweden there is no formal records manager profession, but the archivist often does the corresponding work. That is why this project also includes the archivists´ role in the open government environment.

    This study will reflect upon the archivists´ role in this process and what is needed to ensure a trusted proactive release of public records. To identify what skills, guidelines, knowledge and mandate are needed. The study will focus on StockholmCity’s work on open data, which is an important part of the open government agenda, through the perspective of Stockholm City Archives.

    Scientific contribution:

    Case study methods are used to examine the role of the archivist in the domain of access to public records in an open government and open data environment. The study examines what role an archivist in the public sector currently has, and what knowledge, skills and competence are needed for these new challenges.

    Interpretation of existing work and the perception of the situation by practicing archivists in this changing environment provide valuable data. The case study is based on the City of Stockholm because it is quite progressive in its work on open data. It is now running an open data project, in which the Stockholm City Archive plays an active role. The role of the archivist in practice, experiences and possible needs and missing factors will be explored. Data will be collected by interviews and text analysis. Needed strategies and guidelines will be identified.

    Benchmarking Information Management Practice and Competence in Swedish Organizations2011In: Proceedings of the 5th European Conference on Information Management and Evaluation: University of Insubria, Como, Italy. 8-9 September 2011 / [ed] Walter Castelnovo and Elena Ferrari, Reading, UK: Academic Conferences Limited, 2011, 28-36 p.Conference paper (Refereed)
    Abstract [en]

    As organizations transform towards e-service provision and operations sophisticated, organization-wide approaches to information management are required. However, there is reason to believe that few organizations have developed a fully holistic approach to thinking about developing and managing their information assets to ensure their current and future accessibility and usability. There is an increasing awareness of the need to design systems that ensure information is accessible and re-usable, yet vital information often becomes increasingly inaccessible over time, to the disadvantage of business intelligence, business needs, customer service and regulatory requirements. An extensive survey of the state of the art of information management within Swedish organizations was undertaken to gain an understanding of current approaches, what competence is currently available within organizations and what competencies are perceived to be lacking or need development to ensure sustainable management of information as a business asset. This paper presents insights into how well or poorly records managers’ and archivists’ expertise is incorporated into whole- of-organization strategic planning for information management. It was rare to find collaboration between enterprise information architects and IT professionals with the recordkeeping professionals, who have expertise in structuring information and metadata as well as system requirements that contribute to ensuring long-term preservation, which would potentially minimize the proliferation of legacy systems from which records and information are very costly or impossible to migrate or extract. Many archivists considered that it is not their role to participate in wider information management strategies, preferring to focus on the capture of records into an ’e-archive’ without recognizing that information in the archive is a potentially re-usable business asset. This initial research contributes to an understanding of information cultures within organizations. It is intended to be used as a benchmark: follow-up studies are planned at regular intervals in the future to measure change in practice, attitudes and professional alliances to improve information management.

    Tree Structures in Broadcast Encryption2005Licentiate thesis, monograph (Other academic)
    Abstract [en]

    The need for broadcast encryption arises when a sender wishes to securely distribute messages to varying subsets of receivers, using a broadcast channel, for instance in a pay-TV scenario. This is done by selecting subsets of users and giving all users in the same subset a common decryption key. The subsets will in general be overlapping so that each user belongs to many subsets and has several different decryption keys. When the sender wants to send a message to some users, the message is encrypted using keys that those users have. In this thesis we describe some broadcast encryption schemes that have been proposed in the literature. We focus on stateless schemes which do not require receivers to update their decryption keys after the initial keys have been received; particularly we concentrate on the Subset Difference (SD) scheme.

    We consider the effects that the logical placement of the receivers in the tree structure used by the SD scheme has on the number of required transmissions for each message. Bounds for the number of required transmissions are derived based on the adjacency of receivers in the tree structure. The tree structure itself is also studied, also resulting in bounds on the number of required transmissions based on the placement of the users in the tree structure.

    By allowing a slight discrepancy between the set of receivers that the sender intends to send to and the set of receivers that actually can decrypt the message, we can reduce the cost in number of transmissions per message. We use the concept of distortion to quantify the discrepancy and develop three simple algorithms to illustrate how the cost and distortion are related.

    Powertrain Model Assesment for Different Driving Tasks through Requirement Verification2016In: Proceedings of the 9th EUROSIM Congress on Modelling and Simulation, 2016Conference paper (Refereed)
    Abstract [en]

    For assessing whether a system model is a good candidate for a particular simulation scenario or choosing the best system model between multiple design alternatives it is important to be able to evaluate the suitability of the system model. In this paper we present a methodology based on finite state machine requirements verifying system behavior in a Modelica environment where the intended system model usage is within a moving base driving simulator. A use case illustrate the methodology with a Modelica powertrain system model using replaceable components and measured data from a Golf V. The achieved results show the importance of context of requirements and how users are assisted in finding system model issues.

    A Framework for Credibility Assessment of a Powertrain Model in Driving Simulator Studies2016In: Proceedings of the 36th FISITA World Automotive Congress, 2016Conference paper (Refereed)
    Abstract [en]

    When performing a driving simulator study, validity of the vehicle model for the intended driving task is of key importance; otherwise, the reliability of the study results might be jeopardized. In this paper a framework for real-time credibility assessment of the simulated longitudinal dynamics by a powertrain model in a moving base driving simulator is presented. The framework consists of the physical system model and a quality model which run in parallel in real time. The developed framework has been evaluated by offline simulations, as well as in real-time in a moving base driving simulator. The evaluation results showed that the developed framework can accurately capture the validity of the powertrain model in different driving conditions and provide the credibility level of the simulation results to the simulator operator in real-time.

    A case study of documentation's significance: in ERP system development projects2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Abstract

    In order to stay competitive in today’s changing business world, companies need to manage

    the increased complexity as they evolve. To be able to handle this complexity, many companies

    chose to implement an ERP system. Investing in an ERP system is not something that

    is made in a trice but is a large investment which together with today’s low-profit margins in

    companies makes it essential to keep the costs as low as possible. More than half of the total

    cost for an ERP investment is said to be related to costs for the system’s maintenance and

    support. Documentation is one of the factors which affect this cost, and if it is not made satisfactorily

    it is said to result in a considerable increase of the system’s total cost. This is why

    it is important not to overlook the documentation as a part of ERP system development

    project.

    The purpose with this thesis is to investigate the existing documentation routines in ERP

    system development projects at AB Volvo’s subsidiary Volvo IT, in order to find suggestions

    of improvement for future projects. In order to fulfill the purpose of the study, we formed a

    research question with three sub-questions and through a deep analysis of the empirical material

    we presented the answers to these questions as the conclusions of this thesis.

    Our study is based on an inductive research approach using a case study to gain deeper and

    more helpful qualitative knowledge and data. The empirical data was analyzed using the

    template analysis method where we divided the collected data into appropriate categories.

    The knowledge created through this study is of exploratory, normative, predictive and categorical

    nature.

    After having analyzed the results from our case study we found several suggestions of improvements

    for Volvo IT to use in future projects. For other companies involved in ERP

    system development projects of their own, the conclusions of this thesis will work as valuable

    issues to take into consideration for upcoming projects. We have concluded that the

    main reason behind lacking quality of documentation in the development projects is not the

    unawareness of its importance, but the absence of concrete evidence of high quality documentation’s

    positive effects on a system’s total cost. We believe that in order to achieve documentation

    of high quality, there needs to be a change of attitude to documentation as a

    work task and the task itself must be higher prioritized in the projects. Another important

    suggestion is that a control of the conducted documentation’s quality must be done, not only

    a control of the existence of the right kind of documents. We are of the opinion that a company

    should not allocate resources to create a method of documentation before the importance

    of high quality documentation is clarified. Ultimately, we believe that the system development

    process should be focused around the customer, because of the more frequent use

    of custom made solutions and to help the people in the project to set the right level of abstraction

    on the documentation.

    Abstract [en]

    This thesis is a case study of the search function on the University of Uppsala’s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical. Without a common strategy how to handle information is it very difficult to make good searches on the web site.

    Användbarhetsaspekter i samband med systemutveckling1999Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Denna rapport innehåller en undersökning av vilka aspekter som är avgörande för att en systemutvecklingsprocess leder till slutprodukter med väl användbara gränssnitt. Rapporten innehåller dessutom ett antal riktlinjer för hur en systemutvecklingsmetod kan förbättras med avseende på användbarhet.

    För att genomföra undersökningen har jag valt att utvärdera hur två systemutvecklingsmetoder, SSADM och IDM, hanterar användbarhetsaspekter. Jag har utvärderat dessa metoder utifrån följande frågeställningar: om de stödjer gränssnittsdesign, om de är iterativt användarorienterade, om de involverar designers med speciella gränssnittskunskaper, om de har fokus på användarna, om de innehåller tidiga och kontinuerliga tester av användbarhet, om de har en integrerad utveckling samt om de innehåller stöd för prototyping. Det som framkommer i rapporten är att ovanstående frågeställningar till viss del är avgörande för att säkerställa slutprodukter med väl användbara gränssnitt. Förutom ovanstående aspekter är det dessutom av vikt att ta hänsyn till användbarhet i samband med kravinsamling och kravanalys. Rapporten avslutas med ett antal riktlinjer att ha i åtanke vid design av slutprodukter med användbara gränssnitt.

    Digital divides revisited: towards a model for analysis2004In: Electronic government: Proceedings of the third international conference, EGOV 2004, Zaragoza, Spain, August 30 - September 3, 2004 / [ed] Roland Traunmüller, Berlin: Springer , 2004, 289-292 p.Conference paper (Refereed)
    Abstract [en]

    This paper presents a model for categories of divides, and how these categories are interrelated. The factors are found by a literature study from different countries attempting to measure various divides. The model is based on earlier research on the ‘divide’ and includes: physical access, autonomy of use, know-how and motivation. Depending on the type of digital divide and the local situation, rectifying efforts must address the most crucial factor, which could be any of the four. The paper also introduces the nature and amount of different proposed divides, and relations among factors.

    Learning e-Learning: the restructuring of students beliefs and assumptions about learning2010In: International Journal on E-learning, ISSN 1537-2456, Vol. 9, no 4, 435-461 p.Article in journal (Refereed)
    Abstract [en]

    This paper builds on a case study on e-learning in Sri Lanka with focus on students’ underlying beliefs about how one learns. E-learning programs are most often set up with the assumption that students should think, act and learn independently and with underlying values of constructivism and learner–centred learning. For students used to classroom-based, didactic education the transition to the e-learning paradigm is, however, neither predetermined nor immediate. The objective of this paper is to find out if, and how, the e-learning practice manages to transform students into more independent and self sustaining learners. By drawing on Structuration Theory this study analyzes and compares novice and experienced students’ assumptions about learning when asking for a particular support function, because support needs should change if students start adopting the e-learning view on how learning is achieved. Findings show that students increasingly adopt the e-learning view on learning as they progress through the program. Students take increasingly more ownership of their learning and the teacher is no longer seen as the container of all knowledge. The importance of discussions also increases over time indicating that knowledge is no longer seen as being transmitted but rather created.

    Letters from the field: e-learning students change of learning behaviour in Sri Lanka and Bangladesh2008In: Proceedings of ECEL 2008: 7th European conference on e-Learning, 2008, 29-37 p.Conference paper (Refereed)
    Abstract [en]

    This paper reports the findings from two case studies on e-learning in Bangladesh and Sri Lanka. In these countries much hope is set on e-learning as a means to disseminate education to a larger population, but statistics show that drop out rates from e-learning courses are much higher than from traditional, classroom based, courses. In this paper it is argued that one reason for this is that the introduction of e-learning and a more student-centred learning model involves a drastic shift for students who are brought up in very teacher-centred didactic educational cultures. In order to investigate how this change in learning is perceived by its main stakeholders (i.e. the students) visits to learning centres in Sri Lanka and Bangladesh were made during 2007 and 2008. To capture the students’ opinions an open approach was chosen where students were asked to write letters about which major challenges they experience in changing their learning behaviour and completing the courses. Altogether the study is based on 107 student letters that have been analyzed and coded based on major differences and challenges identified by the students. Findings show that most students find learning on their own to be the major difference. They find this challenging because they feel very distant and because they do not know how to learn on their own. They have difficulties in managing their time and a lack of flexibility combined with a sloppy administration makes it even worse. Students used to being spoon-fed and learning by memorizing obviously need much support in taking ownership of their own learning in order to be able to learn by themselves. By comparing and mapping these findings to solutions suggested by existing research this study therefore suggests that support functions should be provided for students on ‘how to be an online learner’ and on ‘how to learn by yourself’. The teacher interaction and presence should also, at least in the early stages of the course, be frequent and active in order to make the student confident in his or hers ability to learn on their own. Finally, course flexibility (in regards to delivery mode and pace) should be high and much effort should be put into creating a supportive and well-organized administration

    Seven major challenges for e-learning in developing countries: Case study eBIT, Sri Lanka2008In: International Journal of Education and Development using ICT, ISSN 1814-0556, Vol. 4, no 3Article in journal (Refereed)
    Abstract [en]

    By using an extensive framework for e-learning enablers and disablers (including 37 factors) this paper sets out to identify which of these challenges are most salient for an e-learning course in Sri Lanka. The study includes 1887 informants and data has been collected from year 2004 to 2007, covering opinions of students and staff. A quantitative approach is taken to identify the most important factors followed by a qualitative analysis to explain why and how they are important. The study identified seven major challenges in the following areas: Student support, Flexibility, Teaching and Learning Activities, Access, Academic confidence, Localization and Attitudes. In this paper these challenges will be discussed and solutions suggested.

    A Conceptual Framework for E-Learning in Developing Countries: A Critical Review of Research Challenges2009In: Electronic Journal of Information Systems in Developing Countries, ISSN 1681-4835, Vol. 38, no 8, 1-16 p.Article in journal (Refereed)
    Abstract [en]

    This paper presents a critical review of research on challenges for e-learning with a particular focus on developing countries. A comprehensive literature review including 60 papers on e-learning challenges was undertaken for the purpose of understanding how to implement e-learning in developing countries. Research questions were: what has existing research identified as the major challenges for e-learning, and, what differences, if any, are there between developing countries and developed countries in this respect? The literature study found 278 papers which were condensed to 60 based on exclusion and inclusion criteria designed to find papers of best quality as well as papers that clearly investigated well-defined challenges. The research found 30 specific challenges which were grouped into four categories, viz.: courses, individuals, technology and context. The overall conclusion is that these challenges are equally valid for both developed and developing countries; however in developing countries more papers focus on access to technology and context whereas in developed countries more papers concern individuals. A further finding is that most papers focus on one or two categories of challenges; few papers exhibit a comprehensive view. Because challenges are interrelated, based on the findings we propose a conceptual framework of emerging issues for e-learning in developed and developing countries. The framework is useful to guide both practice and research.

    Increasing interactivity in distance educations: Case studies Bangladesh and Sri Lanka2010In: Information Technology for Development, ISSN 0268-1102, E-ISSN 1554-0170, Vol. 16, no 1, 16-33 p.Article in journal (Refereed)
    Abstract [en]

    This paper describes how distance educations in developing countries can enhance interactivityby means of information and communication technologies. It is argued that e-learning involvesa shift in the educational structure from traditional transmission of knowledge to interactivecreation of knowledge. Our case studies are two distance educations in Bangladesh and SriLanka that use different technologies for implementing interactivity; Internet and computersin one case and video and mobile phones in the other. The findings are analyzed based onStructuration Theory and we compare the two approaches based on emerging norms andbeliefs. Findings from both cases show the concurrent enactment of both the transmissionand the interactive structure. Whereas peer collaboration and the use of self-assessment toolsmake students take more ownership of their learning, we also found the idea of a classroomwith an instructive teacher to be deeply rooted in the students’ minds.

    Learning from e-learning: emerging constructive learning practices2009In: Doing IT research that matters, 2009Conference paper (Refereed)
    Abstract [en]

    This research is situated within the field of Information and Communication Technologies for Development (ICT4D) and asks if ICT use can make learning practices change. While constructive learning practices are critical to both individual and societal development, repetitive learning practices are the norm in many developing countries. The study is based on observations and in-depth interviews and uses a structurational approach to understand if and how students views of learning change during an e-learning program in Sri Lanka. We found four constructive learning practices that emerged through technology use; individual exploring, interaction with peers, interaction with teachers, and taking responsibility of the learning. Many constructive learning practices emerged outside the LMS used, in students’ voluntary uses of publicly available resources on the Internet. The study shows that technology use can play a positive role for development, provided an open environment is available; students learn constructive practicesfrom e-learning.

    Using class blogs in 1:1 schools: searching for unexplored opportunities2014In: Computers in The Schools, ISSN 0738-0569, E-ISSN 1528-7033, Vol. 31, no 3, 173-196 p.Article in journal (Refereed)
    Abstract [en]

    This article focuses on class blogs and presents results from 1:1schools in Sweden. While Swedish schools are increasingly usingWeb 2.0 technologies (e.g., wikis and blogs), most of this use is stillatanexperimentalstage.Tofurthertheunderstandingofhowblogsare and can be used, we compare class blogs used in practice withthe fast-growing literature in the field. Previous work suggests eightuses: collaboration, making assignments, journal writing, instruc-tion, posting supplemental material, community building, externalreaders, and prompting. In practice, we found blogs to be used ina fairly narrow way—mainly for instruction and posting supple-mental material. We hope that this article will inspire teachers tofurther their blog use.

Proceedings / [ed] lvana Castano, Panos Vassiliadis, Laks V. Lakshmanan, Mong Li Lee, Springer Berlin/Heidelberg, 2012, 23-33 p.Conference paper (Refereed)
    Abstract [en]

    Currently there exists a multitude of views of service creating problems for designers and users of models with respect to reasoning, description and classification of services. The diversity of conflicting views and definitions suggest that a multi-perspective approach is required to explicate the notion of service. The purpose of this paper is to introduce an integrated view of the service notion based on a literature survey. Our approach is to start with an analysis of service-as-a-resource and argue that this view will benefit from being complemented with a service-as-a-process view. These views are then integrated and represented in a conceptual model.

    Towards a formal definition of goal-oriented business process patterns2005In: Business Process Management Journal, ISSN 1463-7154, E-ISSN 1758-4116, Vol. 11, no 6, 650-662 p.Article in journal (Refereed)
    Abstract [en]

    Purpose – Organizations of today are becoming ever more focused on their business processes. This has resulted in an increasing interest in using best practices for business process re-engineering. Two problems arise in connection to using best practices: how to find a best practice that suits particular purposes, and how to ensure that the process from the best practice has the same nature as the process under re-engineering. The purpose of this paper is to address these issues.

    Design/methodology/approach – The paper suggests using business process patterns, i.e. relatively high level business process models, for making near formal comparison of business processes. The paper analyzes widespread modeling techniques to find out which of them suits the task of building patterns for comparison. Based on this analysis, the state-flow modeling technique is chosen and first steps towards formal definition of business process patterns based on this technique are suggested.

    Findings – A pattern is defined based on the notions of state space, goal, as a surface in the state space, and valid movements towards the goal. A thinkable procedure of constructing patterns is demonstrated on two real-life examples. A hypothetical procedure for comparing process is suggested but it still needs to be verified in practice.

    Originality/value – The originality of the paper is the way the patterns are formulated and the underlying model, the state-flow view of processes, upon which the patterns are founded.

    Towards an Ontology of Value Ascription2016In: Formal Ontology in Information Systems: Proceedings of the 9th International Conference (FOIS 2016), IOS Press, 2016, 331-344 p.Conference paper (Refereed)
    Abstract [en]

    The analysis of value, value ascription mechanisms, and their motivating and influencing factors is useful for decision making processes of both customers and providers. In particular, enterprise modeling can greatly benefit from a proper understanding of value-related notions. Nonetheless, existing value models mainly focus on the value exchange between subjects, disregarding the understanding of “what” value is and of “why” something is valuable. In order to exploit the benefits of value analysis, a precise and rigorous conceptualization, based on foundational ontologies, is needed. To this aim, we present and discuss here a preliminary core ontology of value ascription and we discuss the main issues.

    Aligning Goals and Services through Goal and Business Modelling2009In: Information Systems and E-Business Management, Vol. 7, no 2009Article in journal (Refereed)
    Abstract [en]

    E-services are used as the cornerstones for modelling interaction points of cooperating IT systems, within and between enterprises. So far, research and development of e-services have mainly focused on an operational perspective, such as the development of standards for message exchanges and service coordination. However, on a strategic level, the success of e-services depends on its ability to work as a medium for exchange of business values. In this paper, we present an approach that utilizes goal and business models as the foundation for designing e-services. The approach can be used to ensure that the developed e-services support the desired goals and business values of involved actors. A case st3dy from the Swedish health sector is used to ground and apply the presented approach.
