    A Prototype For HI²Ping Information Security Culture and Awareness Training2012Ingår i: 2012 International Conference on e-Learning and e-Technologies in Education (ICEEE), IEEE Xplore Digital Library , 2012, 32-36 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this short paper, we propose a security culture and awareness training platform that suite different learning styles and preferences. The objective is to operationalize the platform for improving individuals security awareness and learn more about their security mental models as well as how their cultural background influence their perception of security. Useful application of the tool is to enhance the effectiveness of security knowledge transfer in a security incident response process management and to develop staff commitment to security policies at organizations. The tool can also help on enabling a global security culture by creating a common understanding of security best practices. Qualitative results show the tool can play a promising role in security education as it combines different mediums for communicating the required information to fit the audience different learning styles.

    Developing social metrics for security: modeling the security culture of it workers individuals  (Case study)2012Ingår i: 2012 Mosharaka International Conference on Communications, Computers and Applications (MIC-CCA), IEEE Xplore Digital Library , 2012, 112-118 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this short paper we present and discuss the findings of a case study aimed at developing social security metrics for modeling the security culture of certain individuals. Using these metrics we have modeled the security culture of IT workers individuals from Saudi Arabia. We suggest these metrics can be used for modeling and comparing different security cultures to develop a global security culture required for effective global response to cyber security issues. We start by reviewing the latest research on the social aspects of information security. Then we highlight the history of the under-development social security metrics. Afterward we discuss the setup of the case study and the methodology used. Finally, we discuss the experiment results and suggested further research work.

    Security from a Systems Thinking Perspective - Applying Soft Systems Methodology to the Analysis of an Information Security Incident2014Ingår i: Proceedings of the 58th Annual Meeting of the International Society for the Systems Sciences (ISSS 2014), York: International Society for the Systems Sciences ( ISSS ) , 2014, 1-17 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Applying systems theory to information security enables security analysts to consider the socio-technical role of the security system instead of only focusing on the technical part. Systems theory can also equip security analysts with the skills required to have a holistic and an abstract level of understanding of the security problem in their organisations and to proactively define and evaluate existing risks. The Soft Systems Methodology (SSM) developed by Peter Checkland was created in order to deal with unstructured situations where human beings are part of the socio-technical system. In this paper, SSM is applied as a framework to diagnose a real case security incident in an organisation. The purpose of this application is to demonstrate how the methodology can be considered a beneficial tool for security analysts during security incident management and risk analysis. Literature review and experience indicate an existing lack of customisable incident response tools that facilitate communication and elaboration within organizations during incident management. In addition to the fact that these tools are mainly technical and don’t take the human factor into consideration. Using SSM as such, we define the security attack as a human activity transformation system that transforms a security event triggered by an attacker into a security breach that cause damage to the victim organisation. The attack system is then modelled to include a number of dependent activity sub-systems that interact with each other and their environment including the security control activity systems. By having such systemic perception of a security attack, security analysts, we suggest, can have a holistic perception under what conditions a security attack has succeeded and what elements of the socio-technical system and its environment should have been considered in order to mitigate and reduce the risk exposure.

    ST(CS)2 - Featuring socio-technical cyber security warning systems2012Ingår i: Cyber Security, Cyber Warfare and Digital Forensic (CyberSec), 2012 International Conference on, IEEE Xplore Digital Library , 2012, 312-316 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this short paper we propose a socio-technical framework for developing cyber security warning systems. We start by reviewing latest research and theories on socio-technical nature of information systems security. We then show the need to consider the social dimension of information systems security as recommended by number of global security consortiums. Afterward we review the development of some of the main currently existing global cyber security warning systems. Finally we present our suggested socio-technical coordination platform to feature socio-technical enabled cyber security warning systems.

    Barriers in achieving business/IT alignment in a large Swedish company: What we have learned?2015Ingår i: Computers in human behavior, ISSN 0747-5632, E-ISSN 1873-7692, Vol. 51, 715-728 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There are still many organizations that face difficulties in achieving business/IT alignment. Prior research has focused on the positive impact of alignment on overall business performance, while the barriers in achieving business/IT alignment were largely unexplored, especially in regards to the social dimension that refers to the people involved in alignment. Therefore this research is focusing on identifying and investigating the barriers that inhibit achieving social dimension of business/IT alignment in large organizations. A case study is conducted in one of the largest Swedish companies. The data is collected through seven semi-structured interviews, field-notes and the use of company's documents that were thematically analyzed. The research presents a unique case of 19 business/IT alignment barriers of social dimension that have been limited so far and which contribute to the business/IT alignment field. The main findings showed that low understanding of counterpart's environment; poor communication; unclear specifications; limited cooperation and lack of mutual commitment and support inhibits the achievement of alignment between business and IT domains on the social dimension. The results could support the researchers to further elaborate frameworks on how to mitigate social barriers in order to achieve a better business/IT alignment. Besides, the discussed barriers can be of practical use for other organizations trying to achieve business/IT alignment with a focus on the social dimension.

    Amharic-English information retrieval with pseudo relevance feedback2008Ingår i: Advances in multilingual and multimodal information retrieval: 8th Workshop of the Cross-Language Evaluation Forum, CLEF 2007, Budapest, Hungary, September 19-21, 2007 : revised selected papers / [ed] Carol Peters ... [et al.], Berlin ; New York: Springer, 2008, 119-126 s.Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    We describe cross language retrieval experiments using Amharic queries and English language document collection from our participation in the bilingual ad hoc track at the CLEF 2007. Two monolingual and eight bilingual runs were submitted. The bilingual experiments designed varied in terms of usage of long and short queries, presence of pseudo relevance feedback (PRF), and three approaches (maximal expansion, first-translation-given, manual) for word sense disambiguation. We used an Amharic-English machine readable dictionary (MRD) and an online Amharic-English dictionary in order to do the lookup translation of query terms. In utilizing both resources, matching query term bigrams were always given precedence over unigrams. Out of dictionary Amharic query terms were taken to be possible named entities in the language, and further filtering was attained through restricted fuzzy matching based on edit distance. The fuzzy matching was performed for each of these terms against automatically extracted English proper names. The Lemur toolkit for language modeling and information retrieval was used for indexing and retrieval. Although the experiments are too limited to draw conclusions from, the obtained results indicate that longer queries tend to perform similar to short ones, PRF improves performance considerably, and that queries tend to fare better when we use the first translation given in the MRD rather than using maximal expansion of terms by taking all the translations given in the MRD.

    General-Purpose Text Categorization Applied to the Medical Domain2007Rapport (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    This paper presents work where a general-purpose text categorization method was applied to categorize medical free-texts. The purpose of the experiments was to examine how such a method performs without any domain-specific knowledge, hand-crafting or tuning. Additionally, we compare the results from the general-purpose method with results from runs in which a medical thesaurus as well as automatically extracted keywords were used when building the classifiers. We show that standard text categorization techniques using stemmed unigrams as the basis for learning can be applied directly to categorize medical reports, yielding an F-measure of 83.9, and outperforming the more sophisticated methods.

    Dictionary-based Amharic-French information retrieval2006Ingår i: Accessing multilingual information repositories: 6th workshop of the Cross-Language Evalution Forum, CLEF 2005, Vienna, Austria, 21-23 September, 2005, revised selected papers / [ed] Carol Peters, Fredric C. Gey, Julio Gonzalo, Henning Müller, Gareth J. F. Jones, Michael kluck, Bernardo Magnini, Maarten de Rijke, Berlin: Springer Berlin/Heidelberg, 2006, 83-92 s.Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    We present four approaches to the Amharic - French bilingual track at CLEF 2005. All experiments use a dictionary based approach to translate the Amharic queries into French Bags-of-words, but while one approach uses word sense discrimination on the translated side of the queries, the other one includes all senses of a translated word in the query for searching. We used two search engines: The SICS experimental engine and Lucene, hence four runs with the two approaches. Non-content bearing words were removed both before and after the dictionary lookup. TF/IDF values supplemented by a heuristic function was used to remove the stop words from the Amharic queries and two French stopwords lists were used to remove them from the French translations. In our experiments, we found that the SICS search engine performs better than Lucene and that using the word sense discriminated keywords produce a slightly better result than the full set of non discriminated keywords.

    Pseudonymisation of Personal Names and other PHIs in an Annotated Clinical Swedish Corpus2012Ingår i: LREC 2012, Eighth International Conference on Language Resources and Evaluation / [ed] Nicoletta Calzolari et al., 2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    Today a large number of patient records are produced and these records contain valuable information, often in free text, about the medical treatment of patients. Since these records contain information that can reveal the identity of patients, known as protected health information (PHI), the records cannot easily be made available for the research community. In this research we have used a PHI annotated clinical corpora, written in Swedish, that we have pseudonymised. Pseudonymisation means to replace the sensitive information with fictive information for example real personal names are replaced with fictive personal names based on the gender of the real names and family relations. We have evaluated our results and our five respondents of who three were clinicians found that the clinical text looks real and is readable. We have also added pseudonymisation for telephone numbers, locations, health care units, dates and ages. In this paper we also present the entire de-identification and pseudonymisation process of a sample clinical text.

    Shadow Answers as an Intermediary in Email Answer Retrieval2015Ingår i: Experimental IR Meets Multilinguality, Multimodality, and Interaction: 6th International Conference of the CLEF Association, CLEF’15 Toulouse, France, September 8–11, 2015, Proceedings / [ed] Josiane Mothe et al, Springer , 2015, 209-214 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    A set of standard answers facilitates answering emails at customer care centers. Matching the text of user emails to the standard answers may not be productive because they do not necessarily have the same wording. Therefore we examine archived email-answer pairs and establish query-answer term co-occurrences. When a new user email arrives, we replace query words with most co-occurring answer words and obtain a “shadow answer”, which is a new query to retrieve standard answers. As a measure of term co-occurrence strength we test raw term co-occurrences and Pointwise Mutual Information.

    Expanding a dictionary of marker words for uncertainty and negation using distributional semantics2015Ingår i: Empirical Methods in Natural Language Processing, Association for Computational Linguistics , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Approaches to determining the factuality of diagnoses and findings in clinical text tend to rely on dictionaries of marker words for uncertainty and negation. Here, a method for semi-automatically expanding a dictionary of marker words using distributional semantics is presented and evaluated. It is shown that ranking candidates for inclusion according to their proximity to cluster centroids of semantically similar seed words is more successful than ranking them according to proximity to each individual seed word.

    Representing Graphical UML Activity Diagrams as OWL Ontology2007Övrigt (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    Knowledge Management is a strategy to assure that the knowledge of an organization can be shared and reused effectively. It is a systematic process of capturing and communicating knowledge therefore making efficient use of it. Knowledge Representation is the means of representing the knowledge about the world in a machine understandable and process able format. It is a process of formalization of knowledge in such a way that it can used automatically for problem solving. Ontology is popular formalism for knowledge representation. A process is a series of activities that result in an outcome. Process modeling is a technique for the graphical representation of a process. It illustrates the sequence of steps involved in a workflow. Processes can be shared and reused by creating a repository which keeps all the information about them. Such a repository can serve us independent of the domain for which a process is modeled for. The motivation for this research is to create a reusable process repository. Ontology can serve the purpose being a knowledge representation format. Therefore, an ontology is created to express the information captured in a process. UML Activity Model is a commonly used process modeling notation and is adopted for our research. This research aims at to provide a solution for representing UML Activity Model as an Ontology expressed in OWL. We have designed a method for this purpose that defines mapping rules between a UML Activity Model and Ontology. A mapping tool is developed to demonstrate the designed method. To evaluate the validity and usefulness of our research a case study is conducted. Military action scenarios, modeled using UML Activity Model, are taken as input. Consequently they are mapped into ontology, thus expressing behavioral knowledge captured in the process as OWL ontology.

    Characteristics of Finnish and Swedish intensive care nursing narratives: a comparative analysis to support the development of clinical language technologies2011Ingår i: Journal of Biomedical Semantics, ISSN 2041-1480, Vol. 2, nr S1, 1-11 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Free text is helpful for entering information into electronic health records, but reusing it is a challenge. The need for language technology for processing Finnish and Swedish healthcare text is therefore evident; however, Finnish and Swedish are linguistically very dissimilar. In this paper we present a comparison of characteristics in Finnish and Swedish free-text nursing narratives from intensive care. This creates a framework for characterising and comparing clinical text and lays the groundwork for developing clinical language technologies. Methods: Our material included daily nursing narratives from one intensive care unit in Finland and one in Sweden. Inclusion criteria for patients were an inpatient period of least five days and an age of at least 16 years. We performed a comparative analysis as part of a collaborative effort between Finnish- and Swedish-speaking healthcare and language technology professionals that included both qualitative and quantitative aspects. The qualitative analysis addressed the content and structure of three average- sized health records from each country. In the quantitative analysis 514 Finnish and 379 Swedish health records were studied using various language technology tools. Results: Although the two languages are not closely related, nursing narratives in Finland and Sweden had many properties in common. Both made use of specialised jargon and their content was very similar. However, many of these characteristics were challenging regarding development of language technology to support producing and using clinical documentation. Conclusions: The way Finnish and Swedish intensive care nursing was documented, was not country or language dependent, but shared a common context, principles and structural features and even similar vocabulary elements. Technology solutions are therefore likely to be applicable to a wider range of natural languages, but they need linguistic tailoring.

    Co-design Research and Business Development: Case of Scandinavian Airlines (SAS)2014Ingår i: Systemic Practice and Action Research, ISSN 1094-429X, E-ISSN 1573-9295, Vol. 27, nr 5, 465-483 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper is presenting a case study of Scandinavian Airlines Systems (SAS) showing how improvements of service quality aspects with Avatars can be managed with a Co-design research approach. The Co-design practices are carried out in different fields of studies. Some of the key advocates of Co-design originate from business. In this study the four steps of Co-design approach is applied. From the first step of Co-design, through interviews, log analysis and a channel survey, findings show that the failed dialogues with Avatar Eva are mainly concerned with five factors: interactivity; dialogue capability; consistency; knowledge; and synonyms. In the second step, carrying out customer workshops, we suggested ten ideal scenarios for Avatar Eva to perform better. In the third step, SAS decision makers decided to implement the first three scenarios: Eva's synonyms; knowledge and Eva's consistency. In the fourth step, another channel survey was carried out as well as a new log analysis to know the impact of the redevelopment above three scenarios. An important result of the study was that the company adopted a continuous use of Co-design as an approach of continuous improvement of the service quality performed by the Avatar Eva. It also opens a new set of questions framing the relation and transformation between Co-design as a research approach for knowledge creation and Co-design as a method for innovation and service quality improvements. The study presents an Extended Co-design Model, which illustrates how the Co-design inspires staff to use it for other functions within and without the SAS.

    Modelling Epidemic Influenza: A Novel Approach2012Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Modellering av dynamiska förlopp i socio-biologiska komplexa system är långt ifrån trivialt. Behovet av fördjupad förståelse av sådana förlopp är många gånger stort. Vi har presenterat ett oortodoxt förslag på hur spridning av influensa i mänsklig population kan beskrivas och simuleras. Traditionellt använder man sig i huvudsak av två typer av modeller. Den ena bygger på matematiska strukturer där dynamiken beskrivs av kontinuerliga differentialförlopp mellan ett fåtal grovt uppdelade sektioner av populationen. Den andra bygger på diskreta förlopp inom visualiserade kontaktnätverk där varje enskild individ i populationen är representerad. Båda dessa metoder har styrkor såväl som svagheter. Bland svagheterna kan man framförallt lyfta fram svårigheterna med att förklara de flesta av influensans observerade epidemiologiska karaktärsdrag. Ett flertal idéer har framlagts för att förklara dessa anomalier. Bland dessa finns en hypotes som trots sin enkelhet skulle kunna förklara en majoritet av de epidemiologiska karaktärsdragen. Problemet med denna hypotes är dock att man inte kunnat hitta empiriska belägg för den. Vi tror att man kan nå närmare en lösning genom att omtolka signifikansen hos denna hypotes och den epidemiologiska karaktäristikan inom ramen för en annorlunda naturvetenskaplig ontologi. Denna omtolkning visar på en informationsbaserad såväl som fysiskt baserad verklighet. Vi menar då inte det traditionella informationsbegreppet som Claude Shannons teoretiserande bygger på, utan David Bohms `aktiva information', där informationen utgör en objektiv aktiv del av naturen, något som existerar oberoende av ett vetande medvetande eller en observatör. Bohm har gett den aktiva informationen en formell struktur i hans teori om det han kallar för `the implicate order'. Tillsammans med Basil Hiley visade han även att kvantmekaniken kan tolkas på ett sådant sätt att aktiv information utgör en fundamental aspekt av teorin, och att den därigenom även förenklas. Baserat på observationer som gjorts och våra resonemang har vi pekat på att en förståelse av epidemiologiska förlopp kanske kan nås genom att använda ett teoretiskt ramverk grundat på aktiv information. I en planerad kommande doktorsavhandling avser vi att presentera en matematisk modell som ytterligare kan underbygga vår hypotes.

    Abstract [en]

    Analogies can be used in most areas of human communication to highlight points of special interest. The creation of specific, specialised patterns, examples, or analogies for facilitating communication is resource consuming. We therefore hypothesize that there are universal patterns that can be used and reused more economically, compared to specialised patterns, for indexing and communicating knowledge. We have conducted empirical tests with altogether 204 students that each one was given 20 minutes to solve problems from six different scientific areas. The results of our tests show clearly an improvement of their problem solving skill when universal patterns were employed as cognitive aids. The average result of the test group that used universal patterns was 81 per cent higher than that of the control group.

    Abstract [en]

    Analogies can be used in most areas of human communication to highlight points of special interest. The creation of specialised patterns, examples, or analogies for facilitating communication is resource consuming. Therefore, we hypothesize that there are universal patterns that can be used and re-used more economically, than a large set of specialized patterns, for indexing and communicating knowledge. We have conducted empirical tests with 204 students, each of whom was given 20 minutes to solve problems from different scientific areas. The results of our investigation show clearly an improvement of the students’ problem solving skill in the tested areas when universal patterns were employed as cognitive aids. The average score of the test group that used universal patterns was 81 % higher than that of the control group.

    Template-driven Documentation of Best Practices2015Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    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 practices2014Ingår i: Vine: The Journal of Information and Knowledge Management Systems, ISSN 0305-5728, E-ISSN 1474-1032, Vol. 44, nr 2, 249-266 s.Artikel i tidskrift (Refereegranskat)
    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.

    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 Arabia2012Ingår i: Advances in Business-Related Scientific Research Conference (ABSRC): Proceedings OLBIA 2012, 2012Konferensbidrag (Refereegranskat)
    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.

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 Practices2014Ingår i: 2014 47th Hawaii International Conference on System Sciences (HICSS) / [ed] Sprague, R. H., IEEE Computer Society, 2014, 3410-3419 s.Konferensbidrag (Refereegranskat)
    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 Documentation2015Konferensbidrag (Refereegranskat)
    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 Documentation2015Ingår i: Journal of Information and Knowledge Management, ISSN 0219-6492Artikel i tidskrift (Refereegranskat)
    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.

    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.

    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?

    Abstract [en]

    Business modelling can be used as a starting point for business analysis. The core of a business model is information about resources, events, agents, and their relations. The motivation of a business model can be found in the goals of an enterprise and those are made explicit in a goal model. This paper discusses the alignment of business models with goal models and proposes a method for constructing business models based on goal models. The method assists in the design of business models that conform to the explicit goals of an enterprise. Main benefits are clear and uniform goal formulations, well founded business model designs, and increased traceability between models.

    Resource, Process, and Use – Views on Service Modeling2012Ingår i: Advances in Conceptual Modeling: ER 2012 Workshops CMS, ECDM-NoCoDA, MoDIC, MORE-BI, RIGiM, SeCoGIS, WISM, Florence, Italy, October 15-18, 2012.

    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 patterns2005Ingår i: Business Process Management Journal, ISSN 1463-7154, E-ISSN 1758-4116, Vol. 11, nr 6, 650-662 s.Artikel i tidskrift (Refereegranskat)
    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.

    Business Process Support as a Basis for Computerized Knowledge Management2005Ingår i:  Professional Knowledge Management: Lecture Notes in Computer Science , vol 3782, pp. 542-553 / [ed] Althoff. K.D., Springer , 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    One of the major factors behind the less successful implementations of computerized knowledge management systems (KMS) is lack of motivation to use such a system on behalf of the end-users. The authors argue that to create such a motivation, i.e., achieve usability, a computerized KMS should be integrated with a business process support (BPS) system and provide three main functionalities: (1) provision of context, (2) automatic gathering of experience-based knowledge, and (3) an active generalized knowledge base. For creating such an integrated KMS/BPS, the authors suggest to use a state-oriented view on business processes. The paper describes a version of a system built according to this view. The system fully implements the first two functionalities, the third one being under development. The system was operationally tested internally, and it is currently installed at a pilot site. Research work in progress includes creating a formal language for representing an active generalized knowledge base, and investigating the impact of the introduction of an integrated KMS/BPS on the pilot organization.
