    Den perfekta motivationen?: En studie om att påverka ideella arbetares motivation2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studies syfte är att undersöka de faktorer som motiverar ideella arbetare i evenemangsprojekt samt hur projektledare resonerar och reflekterar kring att motivera ideella arbetare. Studien ämnar att ta reda på hur projektledare från fyra olika evenemangsprojekt gör för att motivera ideella arbetare. Resultatet kan bidra till att framtida projektledare får tips kring vilka verktyg de kan använda för att skapa motivation hos sina ideella arbetare.

    Studiens huvudfrågor med tillhörande underfrågor är:

    • Hur agerar projektledare för att skapa motivation hos de som arbetar ideellt i evenemangsprojekt?

    - Vilka delar i projektledarens agerande är de mest framgångsrika gällande att skapa motivation?

    • Hur tänker projektledare kring motivation hos ideella arbetare?

    - Vad motiverar ideella arbetare i evenemangsprojekt?

    Resultaten i studien kommer från den kvalitativa metoden informant- och respondentintervju. Intervjuerna hålls med fyra olika projektledare, en från varje organisation samt två ideella arbetare från varje organisation. Dessa resultat analyseras sedan med hjälp av teorier kring motivation och ledarskap från bland andra Maslow, Herzberg och Deci och Ryan. I slutet på uppsatsen sammanställs resultat och analys till en lista på nio konkreta råd för hur framtida projektledare kan agera för att skapa och behålla motivation hos ideella arbetare.

    Studien visar bland annat att ideella arbetare främst motiveras utav inre motivation när de söker sig till ett ideellt arbete. Men att de under projektet kan variera mellan både yttre och inre motivation och att motivationen är påverkbar från ledarens sida. Ledaren kan bland annat motivera de ideella arbetarna genom att vara närvarande i arbetsuppgifterna och genom att skapa en personlig relation till sina ideella arbetare. Andra sätt att motivera sina ideella arbetare kan vara att skapa en sammanhållning i projektgruppen, genom att situationsanpassa sitt ledarskap och genom att vara tydlig när det gäller information och projektets mål.

    Resurshantering av personer i multiprojektmiljöer2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An important task for project managers in multi-project environments is to effectively choose the right people to the project team. For organizations, it means being able to prioritize and plan human resources among the various projects running in parallel. The purpose of this paper is to describe how a project manager in multi-project environments looks at the allocation of people in their projects. We did our research through literature reviews and interviews with seven project managers.

    The research shows that the studied organizations highlight both the expertise and the personal factors in an election. They do not use any specific personality test to identify their staff. The most important thing for them is instead the area of competence, although personality is seen as something important to complete the project. Why then don´t the different personality models have any impact in the selection? The organizations believe that they are already satisfied and think that the choice of simple manageable methods work well. One obstacle may be that they perceive the instep too high in the form of courses, training, purchasing models, etc., and the investment is perceived as being more costly than the estimated profit.

    A follow-up question to our main research question was how the project managers perceived the need for IT support system for resource management to help the business improve and streamline their processes of allocation of resources. We have, through our literature studies looked at the importance of using a more advanced IT support system for resource management in large organizations, but in the businesses we studied, they are not used. For example, it may be that IT support can mean large economic costs, large rearrangements and extensive training for staff.

    It turned out that those simpler IT support systems as MS Excel in combination with active internal communication is perceived as a sufficiently effective method of resource management particularly for the smaller businesses. Especially in these businesses, it is easier to get background information about potential project members' skills and personal qualities.

    Projektledning för kreativitet: En fallstudie om hur projektledare skapar förutsättningar för kreativitet i ett distansbaserat datorspelsutvecklingsprojekt2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Companies and projects often face the challenge of creating something new to increase their competitiveness. In this process of creating something new creativity is an important factor. By using a creative approach and utilizing creative processes new innovations emerges. An industry that has grown in recent years is the computer games industry. Competition is fierce and for the companies to succeed, the product need that extra something to make it stand out among all the produced games.

    The project manager's role in the creative process and the ability to be creative within a distance based company is not something highlighted by previous research. This formed the basis of our research question:

    How do project managers act to create conditions for creativity among employees in a remotely organized computer game company?

    To answer our question, we chose to make a descriptive case study. The project is based in the Nordic countries with employees worldwide. It is altogether a distance based project with no shared workspace. We interviewed the projects two project managers, and supplemented with a qualitative survey amongst the employees. The collected material was analyzed with a methodology inspired by Grounded Theory and previous research results.

    Three approaches of how the project managers act to promote creativity are evident in their stories. These approaches are trust, availability and tolerance. They form the basis of our model on how the project managers in this case act to promote employee creativity. Besides the three approaches, two concepts emerged as important tools for creativity in the project: motivation and communication. Our conclusion can be described as follows:

    Motivation provides the conditions for creative thinking. By building an organization where project leaders show trust in the ability of employees, and allows tolerance to be a watchword for collaboration, project managers work to improve employee motivation. This will create opportunities for creativity among the employees in this distance based project. Communication is essential for creative work in the project and virtual means of communication a way to increase availability.

    The Project Manager at Work2012In: Makt, Myter och Motstridigheter: Utmaningar i dagens arbetsliv, Karlstads universitet, 2012, 1-15 p.Conference paper (Other academic)
    Abstract [en]

    In the literature there is a common belief that project management is a general theory that is mainly

    about techniques and/or tools used for planning, budgeting, and control. This view has lately been

    questioned due to the fact that it does not give a complete picture of what a project manager actually

    does in their daily work. By including other skills, such as, skills for communication, team building,

    and leadership, a more complete picture of the project management role may be provided. Project

    management research needs more empirical data from project managers about what their role as project

    manager actually means. The purpose of this study is to investigate what it means to work as a project

    manager in small and medium sized organizations. Empirical data is planned to be gathered (in the

    county of Värmland, Sweden) from May through October 2012, using semi-structured interviews and

    participant observations of project managers working in a multi-project management environment.

    Three overlapping analyzes techniques will be used to analyze the gathered data: thematic analysis,

    grounded theory, and narrative analysis. By using these techniques, hopefully this article will expand the

    knowledge and the understanding what a project manager actually does in their daily work.

    A Master Program in Project Management: Experiences from combining hard and soft skills2011In: Nordic Academy of Management (NFF) 2011 Conference, 2011Conference paper (Other academic)
    Abstract [en]

    Project management skills are needed in a growing number of areas, all with specific requirements regarding technical and social competencies. Still, the majority of project management training is focusing on technical tools and techniques, emphasized in standards suggested by global professional project management associations. Uncertainties and unique social settings require a managerial approach different from the linear, rational and analytical view of the world provided by international standards such as the PMBOK Guide. A new approach to project management education is needed that deals with the complexity of today’s project environments. This paper describes a one year master program in project management at the KarlstadUniversity in Sweden. The program is general and focuses on issues regardless of business area or project type, and mix both technical and social skills. The program was initiated in 2002 and more than 200 students have until today been part of the program. In addition to the mandatory courses in the program, several students have, on voluntary basis, passed the IPMA D-level certification. The paper also presents the results from two different types of evaluations showing that the majority of the students have great use of their education in their current employment.

    Business Modelling - Konsortium förenar forskning vid tre högskolor1996Report (Other academic)
    Abstract [en]

    Syftet med business modelling projektet är att undersöka möjligheterna att överbrygga kommunikationsgapet mellan affärsansvariga och systemexperter via användning av gemensamma metoder och arbetssätt.



    Projektets mål är att utreda förutsättningarna för, samt ta fram ramverk för ett integrerat arbetssätt där metoder för affärs- verksamhets- och systemutveckling kombineras i metodkedjor (metoder med olika syfte) och metodallianser (metoder med liknande men kompletterande syfte).



    Projektet drivs av ett konsortium bestående av tre högskolor (Handelshögskolan i Stockholm, Kungliga Tekniska Högskolan och Linköpings universitet) i samverkan med fyra företag (ABB, Ericsson, Posten och Scania). Projektet finansierades av Nutek (numera Vinnova) för projektledning och forskarstuderande. I referensgruppen ingår professorer från de tre högskolorna och erfarna konsulter med spetskunskaper inom verksamhetsutveckling. Projektet slutdokumenterades i boken: "Perspectives on Business Modelling - Understanding and Changing Organisations" (Springer, 1999)

    Proprietär-, fri- och öppen programvara: En studie av användningsmönster och attityder hos privatpersoner2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Antalet programvaror ökar för varje dag och människor använder dagligen en mängd olika sorters programvara både på datorer och på andra enheter. Det finns idag programvara som kallas för fri och öppen programvara som tar upp kampen med gamla klassiska proprietära programvaror. Öppna och fria programvaror släpper sin källkod helt fri så användaren själv har möjlighet att göra ändringar i den programvara som används medan proprietär programvaras källkod är skyddad och hemlig. Dessa tre olika sorters programvaror jämförs och diskuteras utifrån tekniska likheter och skillnader i denna kandidatuppsats.

     

    Syftet med denna kandidatuppsats inom informatik är att undersöka vad privatpersoner som är tekniskt intresserade har för tankar och attityder kring proprietär, öppen och fri programvara och visa vilka tekniska aspekter som prioriteras vid val mellan dem.

     

    I undersökningen har ett kvantitativt angreppssätt bestående av en webbenkät som besvarats av privatpersoner tillämpats. Resultatet från denna enkät har tillsammans med den teori som insamlats visat vilka tekniska funktioner och skillnader som påverkar en privatperson då val av olika sorters programvara ska ske.

     

    Undersökningen har visat att det som användaren prioriterar högst i en programvara är användbarheten som handlar om hur användarvänligt användargränssnittet är och hur lättanvänd en programvara är. Vidare har undersökningen visat att de proprietära programvarorna är överlägsna när det gäller användarvänlighet.

     

    Trots den förmodan som finns om att proprietära programvaror är mycket mer säkra och tillförlitliga än fria och öppna alternativ så har undersökningen även visat att fria och öppna programvaror ofta är lika säkra och tillförlitliga. Ibland överträffar de till och med de proprietära programvarorna i både säkerhet och tillförlitlighet.

     

    Vidare visar undersökningen att fria och öppna programvaror till störst del inriktar sig till utvecklare. Detta för att om användaren ska kunna dra någon nytta av att källkoden finns tillgänglig och möjligheten att själv ändra och anpassa programvaran efter eget tycke så krävs kunskaper inom programmering som en väldigt stor majoritet av alla datoranvändare i världen inte innehar.

     

     

    Nyckelord: proprietär programvara, öppen programvara, fri programvara, proprietary software, open source, free software.

    Webbapplikationsutveckling: Möjliga utvecklingsvägar ASP, PHP, Coldfusion med stöd av XML2001Report (Refereed)
    Abstract [sv]

    Uppsatsen är en litteraturstudie med syftet att undersöka möjliga utvecklingsvägar för Imagon system AB vid utvecklandet av en webbanpassad version av dokumenthanteringssystemet IDA 2000. Uppsatsen riktar sig främst till beslutsansvariga på Imagon men även till andra som finner ämnet intressant. Vi utvärderar tre stora metoder för webbapplikationsutveckling, ASP, Cold fusion och PHP. Vi granskar även fördelar med att använda XML som ersättning för HTML vid utvecklingen. Vi rekommenderar att Imagon använder sig av ASP, framförallt därför att den grundläggande kompetens som behövs finns inom företaget. Vi rekommenderar även användande av XML, främst på grund av metodens framstående informationsstrukturering.

    Den glömda kundgruppen: En leverantörsstudie av den svenska marknaden för standardsystem1996In: Management of Technology, ISSN 1102-5581, no 3, 7-8 p.Article in journal (Other academic)
    Abstract [sv]

    Kan marknaden över administrativa standardsystem karakteriseras som en bransch i omvandling? Detta är en fråga som inspirerade oss till att undersöka hur leverantörer av standardiserade programvaror ser på sin roll idag och den närmaste framtiden. Vår bedömning är att den senska marknaden för standardystem kan utsättas för drastiska förändringar. En kraftig utslagning bland leverantörer och ett radikalt annorlunda produkt- och tjänsteutbud är några exempel

    Standardsystem idag och i framtiden: En leverantörsstudie1996Report (Refereed)
    Abstract [sv]

    Vårt övergirpande forskningsproblem avser att analysera nätverket av affärsrelationer mellan aktörer kring standardsystem på den svenska markanden. Med aktörer avses här kunder, leverantörer och olika former av tredje parter inom branschen för programvaror med kringliggande datorer och tjänster. Tidigare har forskningen kring SIV-metoden för anskaffning av standardsystem gett fördjupade kunskaper om kundens situation på marknaden. För närvarande undersöks hur leverantörer av standardsystem ser på sin roll i branschen.



    Som ett led i detta forskningsarbete genomförde vi under 1992 en leverantörsstudie av hur branschen kring standardsystem ser ut idag respektive kommer att utvecklas i framtiden. Vi har valt ut de 21 största leverantörerna av administrativa standardsystem som opererar på den svenska marknaden. Intervjuer genomfördes med VD, vice VD och/eller i vissa fall med marknadschefen. Intervjuerna ägde rum på företagen under ca 3 timmar och följde en i förväg utarbetad frågemall för att underlätta jämförelese mellan leverantörerna. Frågorna berörde t.ex. företagets affärsidé, kombinerat produkt/tjänsteutbud, konkurrenter resp samarbetspartners, idealt versus faktiskt kundbeteende och visioner om framtidstrender.



    Rapporten har ett fokus på intressanta generella mönster och "highlights" i stället för detaljuppgifter om varje specifik leverantör. Analyserna kretsar kring frågeställningar som glömda kundgrupper, totalleverantör versus nischleverantörer, produktgenerationer ("release"-hantering), långsiktiga affärsrelationer, teknologins betydelse (t.ex. användargränssnitt) och kravspecifikationens roll. Efter feedback på remissutgåvan har vi utökat slutrapporten med några reflektioner kring vad som kännetecknar en konkurrenskraftig leverantör, konsekvenser av den tekniska utvecklingen och om hur vi kan applicera ett nätverkssynsätt inom branschen för administrativa standardsystem.

    Abstract [sv]

    Kan den svenska marknaden över administrativa standardsystem karakteriseras som en bransch i omvandling? Detta är en fråga som inspirerat oss till att undersöka hur samspelet mellan leverantörer och kunder av standardsystem ser ut idag och i framtiden. Eftersom det finns många olika uppfattningar om vad standardystem egentligen är inleder vi med att precisera innebörden i begreppet. Vad som händer inom branschen och vilka förändringar av standardsystem som kan skönjas är vårt huvudsakliga tema för kapitlet. Vi kommer att ha ett fokus på två intressant trender på marknaden, nämligen utvecklingen mot långsiktiga affärsrelationer och så kallade komponentbaserade standardsystem.

    Abstract [en]

    Can the Swedish market in standard application packages be charaterized as an industry in transition? This is a question that inspired us to investigate the interplay between vendors and customers of standard application packages apperas today and will appear in the future. Since there are many opinions concerning what standard application packages actually are, we shall begin by defining the concept. Our main theme in the chapter is the events and changes which can be observed in the industry. We shall focus on two interesting trends in the market, namely the development of long-term business relationships and so-called component-based packages

    Usable privacy for digital transactions: Exploring the usability aspects of three privacy enhancing mechanisms2012Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The amount of personal identifiable information that people distribute over different online services has grown rapidly and considerably over the last decades. This has led to increased probabilities for identity theft, profiling and linkability attacks, which can in turn not only result in a threat to people’s personal dignity, finances, and many other aspects of their lives, but also to societies in general. Methods and tools for securing people’s online activities and protecting their privacy on the Internet, so called Privacy Enhancing Technologies (PETs), are being designed and developed. However, these technologies are often seen by ordinary users as complicated and disruptive of their primary tasks.

     

    In this licentiate thesis, I investigate the usability aspects of three main privacy and security enhancing mechanisms. These mechanisms have the goal of helping and encouraging users to protect their privacy on the Internet as they engage in some of the steps necessary to complete a digital transaction. The three mechanisms, which have been investigated within the scope of different research projects, comprise of (1) graphical visualizations of service providers’ privacy policies and user-friendly management and matching of users’ privacy preferences “on the fly”, (2) methods for helping users create appropriate mental models of the data minimization property of anonymous credentials, and (3) employing touch-screen biometrics as a method to authenticate users into mobile devices and verify their identities during a digital transaction.

     

    Results from these investigations suggest that these mechanisms can make digital transactions privacy-friendly and secure while at the same time delivering convenience and usability for ordinary users.

    Abstract [en]

    We explore how concepts from the field of network science can be employed to inform Internet users about the way their personal identifiable information (PII) is being used and shared by online services. We argue that presenting users with graphical interfaces that display information about the network structures that are formed by PII exchanges can have an impact on the decisions users take online, such as the services they choose to interact with and the information they decide release.

    Users as Prosumers of PETs: The Challenge of Involving Users in the Creation of Privacy Enhancing Technologies2013In: Frameworks of IT Prosumption for Business Development / [ed] Małgorzata Pańkowska, IGI Global, 2013, 178-199 p.Chapter in book (Refereed)
    Abstract [en]

    Frequent contact with online businesses requires Internet users to distribute large amounts of personal information. This spreading of users’ information through different Websites can eventually lead to increased probabilities for identity theft, profiling and linkability attacks, as well as other harmful consequences. Methods and tools for securing people’s online activities and protecting their privacy on the Internet, called Privacy Enhancing Technologies (PETs), are being designed and developed. However, these technologies are often perceived as complicated and obtrusive by users who are not privacy aware or are not computer or technology savvy. This chapter explores the way in which users’ involvement has been considered during the development process of PETs and argues that more democratic approaches of user involvement and data handling practices are needed. It advocates towards an approach in which people are not only seen as consumers of privacy and security technologies, but where they can play a role as the producers of ideas and sources of inspiration for the development of usable PETs that meet their actual privacy needs and concerns.

    The PrimeLife Policy Language (PPL) has the objective of helping end users make the data handling practices of data controllers more transparent, allowing them to make well-informed decisions about the release of personal data in exchange for services. In this chapter, we present our work on user interfaces for the PPL policy engine, which aims at displaying the core elements of a data controller's privacy policy in an easily understandable way as well as displaying how far it corresponds with the user's privacy preferences. We also show how privacy preference management can be simplified for end users.

    Towards Usable Privacy Policy Display & Management2012In: Information Management & Computer Security, ISSN 0968-5227, Vol. 20, 4-17 p.Article in journal (Refereed)
    Abstract [en]

    This paper discusses the approach taken within the PrimeLife project for providing user-friendly privacy policy interfaces for the PrimeLife Policy Language (PPL).We present the requirements, design process and usability testing of the “Send Data?” prototype, a browser extension designed and developed to deal with the powerful features provided by PPL. Our interface introduces the novel features of “on the fly” privacy management, predefined levels of privacy settings, and simplified selectionof anonymous credentials. Results from usability tests showed that users understand and appreciate these features and perceive them as being privacy-friendly, and they are therefore suggested as a good approach towards usable privacy policy display and management. Additionally, we present our lessons learnt in the design process of privacy policy interfaces.

    Usable Transparency with the Data Track: A Tool for Visualizing Data Disclosures2015In: CHI EA '15 Proceedings of the 33rd Annual ACM Conference Extended Abstracts on Human Factors in Computing Systems / [ed] Bo Begole, Jinwoo Kim, Kori Inkpen, Woontack Woo, Association for Computing Machinery (ACM), 2015, 1803-18098 p.Conference paper (Refereed)
    Abstract [en]

    We present a prototype of the user interface of a transparency tool that displays an overview of a user's data disclosures to different online service providers and allows them to access data collected about them stored at the services' sides. We explore one particular type of visualization method consisting of tracing lines that connect a user's disclosed personal attributes to the service to which these attributes have been disclosed. We report on the ongoing iterative process of design of such visualization, the challenges encountered and the possibilities for future improvements.

    Abstract [en]

    The use of mobile smart devices for storing sensitive informationand accessing online services is increasing. At the same time, methods for authenticating users into their devices and online services that are not only secure, but also privacy and user-friendly are needed. In this paper, we present our initial explorations of the use of lock pattern dynamics as a secure and user-friendly two-factor authentication method. We developed an application for the Android mobile platform to collect data on the way individuals draw lock patterns on a touchscreen. Using a Random Forest machine learning classier this method achieves an average Equal Error Rate (EER) of approximately 10.39%, meaning that lock patterns biometrics can be used for identifying users towards their device, but could also pose a threat to privacy if the users' biometric information is handled outside their control.

    Abstract [en]

    Whereas in real everyday life individuals have an intuitive approach at deciding which information to disseminate to others, in the digital world it becomes difficult to keep control over the information that is distributed to different online services. In this paper we present the design of a user interface for a system that can help users decide which pieces of information to distribute to which type of service providers by allowing them to segregate their information attributes into various personalized profiles. Iterative usability evaluations showed that users understand and appreciate the possibility to segregate information, and revealed possible improvements, implications and limitations of such an interface.

    Abstract [en]

    Possible attacks on mobile smart devices demand higher security for applications handling payments or sensitive information. The introduction of a tamper-proof area on future generations of mobile devices, called Trusted Execution Environment (TEE), is being implemented. Before devices with embedded TEEs can be deployed to the public, investigations on usability aspects of Trusted User Interfaces (TUI) are needed. This article describes the process we have followed at gathering requirements, prototyping and testing suitable designs for TUIs in combination with a touch-screen biometric system. At the end, we present relevant findings of a pilot study that we have conducted using an Experience Sampling Method (ESM) as part of our ongoing work.

    What Would It Take for You to Tell Your Secrets to a Cloud?: Studying decision factors when disclosing information to cloud services2014In: Secure IT Systems: 19th Nordic Conference, NordSec 2014, Tromsø, Norway, October 15-17, 2014, Proceedings, Springer, 2014, Vol. 8788, 129-145 p.Conference paper (Refereed)
    Abstract [en]

    We investigate the end users’ behaviours and attitudes with regards to the control they place in the personal information that they disclose to cloud storage services. Three controlled experiments were carried out to study the influence in users’ decisions to retain or surrender control over their personal information depending on different factors. The results of these experiments reveal, among other things, the users’ willingness to surrender control over personal information that is perceived as non-sensitive in exchange for valuable rewards, and that users would value the possibility of knowing and controlling the parties who are granted access to their data in the cloud. Based on the results from the experiments we provide implications for the design of end-user tools that can promote transparency and accountability in cloud computing environments.

    ------------------------------------------------



    There is a need for a systematic way of working when planning for standard application packages in organizations. We have tried to develop a method for this field - the SIV method (Standard Application Packages in Organizations, in Swedish: Standardsystem I Verksamheter). The SIV method takes the customer's situation as a starting point - a customer view. Furthermore, occasions have been described where a dialogue between the customer and the vendor is necessary, e.g. demonstrations and negotiations. The SIV method gives a survey of the field with emphasis on adaptation of activities and standard application packages to each other.



    This report is focusing on "adaptation" of standard application packages. A similar report has been done for "choice" of standard application packages.

    Verksamhetsutveckling - Att anpassa standardsystem1983Book (Refereed)
    Abstract [sv]

    Syftet med standardsystem är att tjäna tid och pengar. Ett standardsystem kan även ge nya möjligheter att effektivisera en verksamhet. Finns det några problem vid anskaffning av standardsystemet? Ja, alltför ofta väljs standardsystem på ett för dåligt underlag om verksamhetens krav och behov. Sedan underskattar man resurserna för anpassning av standardsystem och verksamhet till varandra.



    Denna bok behandlar en metod för att anpassa standardysstem i ett företags verksamhet (SIV-metoden). Boken innehåller praktikfall från Alfa-Laval och Philips som exempel på metodanvändningen. Boken vänder sig till personer som arbetar med att förändra standardsystem och det egna verksamhetsområdet mot varandra med de konsekvenser detta kan innebära.



    Ibland behöver vi göra ett förval bland urvalet av standardsystem på marknaden. En metod för detta presenteras i boken: " Verksamhetsutveckling - Att välja standardsystem" (Studenlitteratur, 1984) som kan ses som ett komplement till denna bok.

    Erfarenheter från (ny)val av standardssytem för BILL-projektet inom Arla1983Report (Refereed)
    Abstract [en]

    Arla genomförde under 80-talet ett upphandlingsprojekt för standardsytem som gick under benämningen BILL- projektet med följande delsystem:



    - Betalningssystem (B)

    - Inköpssystem (I)

    - Leverantörsreskontrasystem (L)

    - Likviditetsplaneringssystem (L)



    Projektgruppen utnyttjade SIV-metoden för val och anpassning av standardsystem. Arbetet med valprocessen finns dokumenterad i två praktikfallsrapporter. Projektgruppen genomförde ett preliminärval (V-rapport V-5201) som sedan efter ändrade förutsättningar för projektet ledde fram till ett nyval av standardsystem V-rapport V-5301). Rapporterna beskriver noggrant hur SIV-metoden användes i BILL-projektet samt erfarenheter av preliminärval och nyval av lämpligt standardsystem för verksamheten

    Verksamhet och standardsystem: Hur kan vi få dessa att närma sig varandra?1982In: Data, nr 10, 1982, sid. 38-40Article in journal (Refereed)
    Abstract [sv]

    Vem har inte upplevt problem med standarsystem som skall installeras i en större verksamhet? Problemen blir inte mindre om företaget redan har en egen datoranläggning. Viss tid ägnas åt att jämföra olika system och sedan välja något. Därefter tror man ju att det mesta arbetet är gjort. "Det är bara att installera och köra systemet".



    I själva verket är det stora jobbet efter val, nämligen att se till att verksamhetens krav och behov står i rätt nivå i förhållande till standardsystemets möjligheter. Det gäller att ta tillvara standardsystemets möjlighet så långt det är riktigt i förhållande till de behov och krav som verksanheten reelt har.



    Ett misstag som ofta görs i samband med standardsystem är att man inte tittar på vilka krav och behov som verksamheten har överhuvudtaget. "Standardsystemet blir verksamhetens kravspecifikation". Riskerna med detta synsätt är uppenbart:

    - Har man klart för sig vad denna verksamhet egentligen skall göra?

    - Finns konkreta mål?

    - Finns funktioner och uppgifter definierade och hur skall dessa hanteras?



    Om ovanstående finns borde också krav finnas på hur och vad standardsystemet skall göra. Vad är då verksamhetens krav? Vem/vilka bestämmer detta?



    Krav ställs från olika intressenter. Verksamhetsledaren har behov av övergripande information, medan de som arbetar mera operativt har mera detaljerat informationsbehov. Standardystemet bör kunna tillgodose båda kategorierna. Standardsystemet är specificerat (givet) på vad det gör. Verksamheten är också (förhoppningsvis) beskrivet på vad som görs/skall göras. "Det gäller att se på hur väl standardsytem och verksamhet passar ihop!"



    Träffytan bör således vara god redan från start. Viktigt är också att de centrala funktionerna i verksamheten finns med i standardsystemet. Erfarenhetsmässigt vet vi att en verksamhet definitivt inte är något bestående. Därför är det möjligt och ofta riktigt att förändra verksamheten mot standardsystemet för att utnyttja standardsystemet bättre eller för att undvika dyra förändringar i standardsystemet. I artikeln presenteras ett konkret arbetssätt, kallad SIV-metoden, för anpassning av verksamhet och standardsystem mot varandra

    Att välja rätt standardsystem1984In: Data (Nordisk datanytt), nr 10, 1984, sid. 50-52Article in journal (Refereed)
    Abstract [sv]

    Vi står inför att välja standardsystem. Vårt mål är att standardsystemet skall ge ett effektivt bidrag till verksamheten. Syftet är också att tjäna tid och pengar jämfört med egenutveckling. Et sätt att välja är att köpa det standardsystem som vi omedelbart fastnar för. Risken är då att vi inte ser de svårigheter och nackdelar som ofta finns. Vi bländas lätt av de positiva möjligheter som erbjuds genom standardsystemet. Vi går in i valprocessen med en förutfattad mening.



    Ett alternativt sätt att välja är att mera noggrant jämföra tänkbara standardsystem mot den egna verksamheten. Vi behöver då ta ställning till en mångfald olika faktorer för att kunna välja "rätt" standardsystem. En systematisk metod hjälper oss att få en överblick. Vi får en säker grund att stå på för att dra riktiga slutsatser om standardsystemens möjligheter och brister

    Verksamhetsutveckling - Att välja standardsystem1984Book (Refereed)
    Abstract [sv]

    De flesta företag köper idag färdiga standardsystem, i stället för att programmera, när man datoriserar olika rutiner.



    Att välja system innebär att vi jämför företagets behov med vad som finns på marknaden. Arbetet kan ses som en beslutsprocess där vi successivt väljer bort standardsystem så att till slut det "bästa" alterntivet återstår. Boken presenterar en metod för bättre planering av Standardsystem I Verksamheter (SIV) med tonvikt på valproblematiken. SIV-metoden omfattar ett antal steg, behovsnanalys, förutsättningsanalys, markandsundersökning, leverantörsbedömning, offertbegäran, jämförelse, urval, demonstration, behovskomplettering, utvärdering, preliminärval, testkörning, förhandling, beslut och delgivning.



    Ibland behöver vi ändå förändra standardsystemet och/eller den egna verksamheten. En metod för detta presenteras i boken: " Verksamhetsutveckling - Att anpassa standardsystem" (Studenlitteratur, 1983) som kan ses som ett komplement till denna bok.

    Identify User Profiles in Information Systems with Unknown Users: A database modelling approach2006In: International Journal of Public Information SystemsArticle in journal (Refereed)
    Abstract [en]

    Most traditional models for system development presuppose that users of the system are known and possible to communicate with. If this is not achievable traditional design methods are less usable in order to analyze and describe the requirements of the users. This paper proposes to complement view design with ideas based on interaction design and semiotics and aims to describe the requirements and wishes of potential and unknown users in information systems supported by image or multimedia databases. In the paper the activity steps of view modelling are brought together with persona techniques from interaction design. The outcome of the proposed method reduces the amount of work considerably and, in addition, reduces the problems associated with involving users in the design process. In addition it forms the basis for the specification of a more informative study to increase the acceptability of databases in public environments

    Konceptuell modellering av multimediadatabaser-går det?2000Chapter in book (Refereed)
    Abstract [sv]

    Databaser modelleras bäst - eller möjligen endast - med användning av konceptuell modellering. Detta är en sanning för traditionella databaser. Men gäller det också för databaser som lagrar information från olika datakällor? Är det rimligt att arbeta med begreppen objekt, variabler och relationer när vi skall modellera användarnas syn på bilder, ljud, eller videodata var för sig eller tillsammans? Kan vi dessutom överhuvudtaget anlägga en konceptuell syn på upplevelser av en bild eller ett musikstycke? Vad händer när vi kommer utanför modellens traditionella användningsområden? Ger metoden en möjlighet att även modellera mer ostrukturerad och sammansatt information? Detta kapitel för ett resonemang om några konsekvenser som blir följden av att använda konceptuell modellering vid design av multimediadatabaser. Studien är explorativ och är en del av ett forskningsarbete

    A Rule-Based Approach for the Recognition of Similarities and Differences in the Integration of Structural Karlstad Enterprise Modeling Schemata2010In: / [ed] Bommel, P. van, Hoppenbrouwers, S., Overbeek, S., Proper, E. & Barjis, J., Springer Netherlands, 2010, 177-189 p.Conference paper (Refereed)
    Abstract [en]

                                                                                

    In this paper, we address the recognition of similarities and differences in schema integration while applying the notation in the Karlstad Enterprise Modeling approach. In doing so, we describe and present a set of “if -then” rules. In these rules, we make use of both concept name comparison and comparison of concept neighborhoods (their surroundings). Following the classification of schema matching approaches given by [26], the rules are classified as a composite schema-based matching approach. The rules should first of all be viewed as a step towards a semi-automatic method for the recognition of similarities and differences in the integration of structural Karlstad Enterprise Modeling schemata. By applying the proposed rules, several problems, such as homonyms and synonyms, might be recognized that otherwise could pass unnoticed.

    Aspects of the Classification Dependency in the Integration of Structural Karlstad Enterprise Modelling Schemata2012In: ECIS 2012 Procedeeings, 2012Conference paper (Refereed)
    Abstract [en]

    In this paper, we address the classification dependency used to illustrate that one concept is an instance-of another concept. In doing so, we present four important aspects of the classification dependency in the integration of implementation-neutral Karlstad Enterprise Modelling schemata. First and second, the classification dependency can be used not only to recognise and resolve power types but also to recognise and resolve homonyms. Third, in inference rules, the classification dependency can be used to deduce both new concepts and dependencies from already existing ones. Fourth, the classification dependency can be used to counter the occurrence of semantic loss and maintain the vocabulary used in the source schemata. The classification dependency can even be used to semantically enrich the integrated conceptual schema. The four aspects of the classification dependency should also be viewed as important aspects to take into account during the development of a semi-automatic method for the integration of implementation-neutral structural EM schemata. Finally, by applying the classification dependency, several problems, such as power types and homonyms, might be recognised that otherwise could pass unnoticed in the integration process.

    Bridging the Gap between Comparison and Conforming the Views in View Integration2006In: Local Proceedings of the 10th East-European Conference on Advances in Databases and Information Systems / [ed] Manolopoulos, Y., Pokorný, J. & Sellis, T., 2006, 184-199 p.Conference paper (Refereed)
    Abstract [en]

    View integration is a complex, error-prone and time-consuming task.Therefore there is a need to decompose the integration methods into smallerwell defined phases where different techniques are applied. Most of themethods used today is composed of, or at least is a mixture of, the followingfour phases: pre-integration, comparison of the views, conforming the viewsand merging and restructuring, and most of the methods put focus on phase 2and 3. Despite of this there is a gap between these two phases. To bridge thisgap a framework has been developed. In the framework Inference Rules (IR)are used, together with Enterprise Modeling (EM) as the canonical modelinglanguage, to deduce dependencies that are not conflicting from dependenciesthat are or have been identified as an inter-schema property. Three researchquestions regarding why, how and when IR should be applied in viewintegration are analyzed and discussed and it is argued that the framework maynot only improve view integration as such but also improve the applied conflictand inter-schema resolution techniques.

    Schema Integration: How to Integrate Static and Dynamic Database Schemata2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Schema integration is the task of integrating several local schemata into one global database schema. It is a complex, error-prone and time consuming task. Problems arise in recognizing and resolving problems, such as differences and similarities, between two schemata. Problems also arise in integrating static and dynamic schemata. In this thesis, three research topics are addressed: Maintaining Vocabulary in Schema Integration, Integration of Static Schemata and Integration of Static and Dynamic Schemata, while applying the notation in the Enterprise Modeling approach.

    In Maintaining Vocabulary in Schema Integration an analysis of what semantic loss is and why it occurs in schema integration is conducted. Semantic loss is a problem that should be avoided because both concepts and dependencies might be lost. In the thesis, it is argued that concepts and dependencies should be retained as long as possible in the schemata. This should facilitate user involvement since the users’ vocabulary is retained even after resolving similarities and differences between two schemata.

    In Integration of Static Schemata two methods are developed. These methods facilitate recognition and resolution of similarities and differences between two conceptual database schemata.  By applying the first method, problems between two schemata can be recognized that otherwise could pass unnoticed; by applying the second method, problems can be resolved without causing semantic loss by retaining concepts and dependencies in the schemata.

    In Integration of Static and Dynamic Schemata a method on how to integrate static and dynamic schemata is developed. In the method, focus is put on pre- and post-conditions and how to map these to states and state changes in the database. By applying the method, states that are important for the database can be designed and integrated into the conceptual database schema. Also, by applying the method, active database rules can be designed and integrated into the conceptual database schema.

    View Integration in Conceptual Database Design: Problems, Approaches and Solutions2006Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    View integration is a complex and time-consuming task because there are several problems that need to be addressed. Two such problems are conflict identification and conflict resolution. Conflicts occur because end users may define concepts on different levels of abstraction and because end users may name concepts differently. Therefore there is a need for methods that can cope with these problems when applying the chosen conceptual modeling language. The aim of this thesis is to develop a method for view integration in conceptual database design in which the dependencies of the Enterprise Modeling approach are applied. For this purpose four research studies have been conducted and each study is presented in one paper. In the first study the problem of semantic loss during view integration is addressed; in the second, the problems of identification and resolution of the homonym conflicts are addressed; in the third, the problem of how to define both databases and software components using Enterprise Modeling as a generic and integrated approach are addressed; and finally, in the fourth study, the problems of applying inference rules for conflict simplification or resolution and for interschema property simplification or resolution are addressed. These research studies together with the five introductory chapters contribute to answering the overall research question: In what way is view integration supported by applying the semantic dependencies of the Enterprise Modeling approach? In this thesis it is argued that using the dependencies of the Enterprise Modeling approach simplifies the view integration process and using the proposed resolution techniques for name conflicts reduces the possibility of semantic loss occurring.

    Abstract [en]

    We view the database as a part of a living language and therefore put focus on the dialectical relation between the spoken language and a database represented as a conceptual database schema. We assert that the discrepancy between the spoken language and a database needs to be addressed and minimized. Wealso assert that all concept names need to be retained as long as possible in conceptual database design because otherwise we may end up with a state of concept name compression and semantic loss

    Problem-Based Learning in a Programming Context: Planning and Executing A Pilot Survey on Database Access in a Programming Language2009In: Information Systems Development: Towards a Service Provision Society / [ed] Papadopoulos, G.A, Wojtkowski, G., Wojtkowski, W., Wrycza, S. & Zupancic, J. (eds.), Springer, 2009, 867-875 p.Conference paper (Refereed)
    Abstract [en]

    In this chapter we describe a pilot survey on applying problem-based learning (PBL) in an undergraduate programming course. During the course the students have applied PBL as a complement to traditional teaching and learning techniques. The PBL problem in this survey combines both knowledge about programming and knowledge about databases. We argue that to handle programming the students have to learn programming according to the deep approach to learning in order to be able to apply their knowledge in new programming situations and contexts. The result from this pilot survey indicates from both a tutor and a student perspective that PBL could be one method to reach a deeper understanding on how to access databases in a programming language.

    Towards a Framework for Schema Quality in the Schema Integration Process2012In: Emerging Topics in the Practice of Enterprise Modeling: 5th IFIP WG 8.1 Working Conference, PoEM 2012, Rostock, Germany, November 7-8, 2012, Short Paper Proceedings / [ed] Kurt Sandkuhl, Ulf Seigerroth, Janis Stirna, 2012, 60-71 p.Conference paper (Refereed)
    Abstract [en]

    In this paper we analyze and discuss schema quality in the schema integration process. In doing so, we apply a framework for evaluating the quality of a conceptual schema (e.g. conceptual database schema). In our analysis we combine quality factors and quality metrics with the schema integration process, which is often described as having four distinct phases: pre-integration, comparison of the schemata, conforming the schemata and merging and restructuring. As its main contribution, the paper offers not only new insights on how to improve the quality of the integration process but also a suggestion that the definition of a high quality schema differs between the phases in the schema integration process.

    Semi-Automatic Schema Pre-Integration in the Integration of Modeling Language Independent Behavioral Schemata2012In: ThinkMind: eKNOW 2012, The Fourth International Conference on Information, Process, and Knowledge Management / [ed] Mauri, J.L & Lorenz, P., IARIA Conference , 2012, 12-17 p.Conference paper (Refereed)
    Abstract [en]

    In this paper, we address schema pre-integration in the integration of modeling language independent behavioral schemata. In doing so, we propose and present a set of tasks that should be carried out not only to improve and clarify the meaning of a schema, but also to facilitate the resulting time consuming and error-prone phases in the integration process. Due to the complexity of schema pre-integration, domain experts and repositories (e.g. ontologies) are still important sources of knowledge and should therefore be involved during the whole integration process. As its main contribution, the paper offers new tasks to perform in the schema pre-integration process as well as an adjusted and enriched work of previously presented tasks for schema pre-integration.
