    How does the alignment of IT to business strategy affect the organisation of the IT function?2008Student thesis
    Abstract [en]

    Date: 2008-06-04

    Purpose: The primary goal of this research is to describe the IT function and examine how its alignment to an organisations strategy affects the way it is organised.

    Method: The chosen method was a purely theoretical examination with the use of the case study of Windham International as primary resource and secondary resources such as book and literature review used for the thesis.

    Research Questions: How does the alignment of IT to business strategy affect the organisation of the IT function?

    Conclusion: One of the findings was that a few researchers seem to suggest that the centralized mode of organising IT was symbolic of the past, while outsourcing and decentralization are the modern approach to organising IT. Wyndham International shows the opposite, after the introduction of the CIO in 2002, centralization was the chosen mode of organisation because that was what would best fit the new strategic approach of the organisation. Insourcing rather than outsourcing proved to be a winning formula.

    In the search of the student's role in innovation ecosystems2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract 

    Level: Master thesis in Innovation and design , 30 credits

    Institution: School of Innovation, Design and Technology, Mälardalen University

    Author: Cornelia Alenbring (98/05/24)  

    Title: In the search of the student's role in innovation ecosystems

    Supervisors: Anders Vikström, Erik Bjurström

    MDU examinator:Yvonne Eriksson

    Keywords: “ecosystems for innovation”, “eco systems for social innovation”, “social innovation ecosystems”, “quadruple helix” “students- innovation ecosystem” “students role in innovation ecosystems”

    Purpose: The purpose of this study is to explore the specific role of students in innovation ecosystems. By gaining a deeper understanding of their role, this research aims to contribute to a more nuanced micro-dynamic perspective on the role of students in innovation ecosystems. This thesis explores conceptualizations and metaphors of innovation ecosystems with the aim of exploring different theorizing in the field, related to the role of students within those. 

    Research question: What is the role of students in innovation ecosystems?

    Method: The study was based on a qualitative method. The empirical data was collected through semi-structured interviews and observations using focus groups with 5 actors within the public, academia, industry and civil society.

    Conclusion: The role of the student is at the heart of the innovation ecosystem metaphor - that of emergence and co-evolution. Rather, the empirical evidence of this thesis concurs that the roles available to students also depend on other actors taking them seriously, and that the reasons for less than optimal exchange between students and other actors deserves further investigation.  It is an interesting observation that students fall between the system perspective’s grand theorizing and pedagogics’ narrower focus on education: - So what is the point of pursuing a research approach where either students or ecosystems are not mentioned? There is an obvious gap in where the abstract level of the system perspective, whilst it can serve as an overview of the concept,  does not specify actors and misses to provide a micro perspective on what is occurring between actors, that could explain how it all happens. Are students rather representatives of the civil society, or of what Powell referred to ‘amphibians’, or representative of nothing but themselves as individuals-in-the-making, as a representative of becoming itself and emergence in itself – through their interaction on a campus which they don’t own, but inhabit? And what do companies really want when they want to be a campus? What is special about a campus and life on a campus? What is the very essence of it?

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

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

    Användbarhet på Mälardalens Högskolas nya webbplats2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Problem: Användbarhet på akademiska webbplatser är viktigt trots att de inte är utsatta för konkurrens på samma sätt som andra typer av webbplatser. Dagens teknik underlättar utformningen av en webbplats, men bara för att tekniken finns för att enkelt göra en webbplats innebär det inte automatiskt att den blir användbar. Utvärderingar av användbarhet ur användarens synvinkel är viktiga och kan göras tidigt och kontinuerligt genom hela utvecklingsprocessen. När webbplatsen har tagits i bruk kan det vara av intresse för den som förvaltar webbplatsen att göra en ny utvärdering av vad användarna tycker om användbarheten på webbplatsen.

    Syfte: Syftet är att undersöka och analysera vad studenterna vid Mälardalens högskola anser om den nya webbplatsens användbarhet samt att ta reda på om ytterligare förbättringar kan göras.

    Metod: Undersökningen genomfördes med hjälp en enkät med 19 slutna och en öppen fråga. Frågorna i enkäten var baserade på en heuristisk utvärderingsmetod med användbarhets¬principer som utarbetats av Jakob Nielsen. I denna undersökning har principerna kompletterats med olika anpassningar, för webbplatser, för att kunna utforma en modell som kan tillämpas för att utvärdera användbarhet på Mälardalens högskola nya webbplats.

    Resultat: Resultatet i undersökningen visar att det är svårt att dra någon generell slutsats om studenterna anser att användbarheten på webbplatsen är bra eller dålig. Inom vissa principer anser studenterna att användbarheten är mycket bra och inom andra principer är användbarheten sämre, vilket gör att det är svårt att ge ett enhetligt betyg till webbplatsen med avseende på användbarhet. Av de 19 frågor som fanns med i enkäten var det 13 som översteg 67 procent positiva svar vilket vi har tolkat som ett godkänt resultat för webbplatsen.

    Using NLP Tools to Detect Ambiguities in System Requirements - A Comparison Study2022In: CEUR Workshop Proceedings, CEUR-WS , 2022, Vol. 3122Conference paper (Refereed)
    Abstract [en]

    Requirements engineering is a time-consuming process, and it can benefit significantly from automated tool support. Ambiguity detection in natural language requirements is a challenging problem in the requirements engineering community. Several Natural Language Processing tools and techniques have been developed to improve and solve the problem of ambiguity detection in natural language requirements. However, there is a lack of empirical evaluation of these tools. We aim to contribute the understanding of the empirical performance of such solutions by evaluating four tools using the dataset of 180 system requirements from the electric train propulsion system provided to us by our industrial partner Alstom. The tools that were selected for this study are Automated Requirements Measurement (ARM), Quality Analyzer for Requirement Specifications (QuARS), REquirements Template Analyzer (RETA), and Requirements Complexity Measurement (RCM). Our analysis showed that selected tools could achieve high recall. Two of them had the recall of 0.85 and 0.98. But they struggled to achieve high precision. The RCM, an in-house developed tool by our industrial partner Alstom, achieved the highest precision in our study of 0.68.

    Golfens IT-system: förändrade interaktioner2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Problem: Hur såg kundrelationerna ut innan det nya IT-systemet infördes och hur ser kundrelationerna ut med ett nytt IT-system? Kundrelationer som tidigare har hanterats via telefon eller på plats har ersatts av dagens lösning med ett IT-system som går att komma åt via Internet och ger mer möj-lighet till självbetjäning. Detta leder till frågorna: Vilka för-ändringar har IT-systemet medfört? Hur har interaktionen påverkats?

    Syfte: Att beskriva och förklara hur införandet av ett nytt IT-system påverkat interaktionen (relation) mellan ”kund” och leverantör vid en tidpunkt 5 år efter systemets införande. Med kund avses golfspelare och med leverantör avses golfklubb.

    Teori & Metod: Teoriavsnittet består av två delar. Avsnittet om IT-system tar upp anledningar till införande och vilka som använder systemet. Avsnitt om kundrelationer och IT tar upp Inter-net, kundrelationer med IT och självbetjäning samt nackde-lar. Empirin har sammanställts genom besöksintervju hos Svenska Golfförbundet, telefonintervju hos 10 olika golf-klubbar, samt enkäter hos 30 medlemmar från Västerås GK och 10 medlemmar från Skerike GK.

    Resultat: Kundkontakten med medlemmarna går från att vara mer personliga möten till att bli mer automatiserade med mer e-postkontakt. Medlemmarna bokar sina starttider, anmäler sig till tävlingar och ändrar handicap alltmer via Internet. Golfklubbarna har bra uppsikt över vilka som är ute och spelar.

    Studentguiden Västerås: En rapport om hur en studentguide produceras - från uppdrag till leverans2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vårt examensarbete har varit att producera en studentguide om Västerås till

    företaget Västerås & Company. Västerås & Company har i uppdrag att

    marknadsföra Västerås Mälarstaden till externa kunder som en attraktiv stad för

    företagsetablering, boende, konferenser/kongresser, högskolestudier och

    fritidsturism. Västerås & Company har producerat ett antal broschyrer som är

    riktade till olika målgrupper.

    Syftet med vår studentguide är att den ska locka presumtiva studenter till Västerås

    stad men även innehålla nyttiga fakta för nyinflyttade studenter.

    För att uppnå bästa resultat med vår studentguide har riktlinjerna i

    informationsdesign använts. Vi har under arbetets gång använt oss av Rune

    Petterssons modell ”

    2001, sid.51-55

    Från uppdrag till leverans – en kreativ process” (Pettersson).

    Vid insamling av material och vid utformning av broschyren har vi vänt oss till

    vår målgrupp. De har via två webbenkäter, en fokusgrupp och en utprovning

    hjälpt oss att kunna tillfredsställa målgruppen. Vi har även gjort en textanalys av

    materialet för att få en uppfattning om dess läsbarhet.

    Våra slutsatser är att det av högsta grad är viktigt att lära känna sin målgrupp och

    att inte underskatta den tid det kan ta att lära känna den. Att använda sig av

    riktlinjerna för informationsdesign gör att materialet blir mer användaranpassat.

    Dessutom har ”meddelandet” en bättre chans att nå fram och tillfredsställa

    mottagaren. Petterssons modell ”

    Challenging Models: Formalizing Quests in Gamified Systems for Behavioral Change2023In: Proceedings - 2023 ACM/IEEE International Conference on Model Driven Engineering Languages and Systems Companion, MODELS-C 2023, Institute of Electrical and Electronics Engineers Inc. , 2023, p. 747-756Conference paper (Refereed)
    Abstract [en]

    Tasks performed by users in exchange for some reward, also known as quests or challenges, are one of the essential elements found in gamified systems, including systems for behavioral change. These elements can be tailored to specific players, according to their profile features and past performance, in order to deliver a more personalized and motivating experience. However, in order to automatically generate challenges, a formal, generalizable model of the essential building blocks of such game elements and their internal relations is needed. Although some work has been carried out in the past to define quests and challenges, a widely agreed-upon definition is still missing. Such an abstract definition should be employable across different application domains and scenarios and be flexible with respect to implementation details and human factors. In this work, we employ a model-driven approach to (1) propose a formal definition of quests and challenges in gamified systems, focusing on systems for behavioral change in the mobility domain, (2) model quests by means of a Domain-Specific Language implementing the proposed definition, and (3) take the first steps towards automatic rule generation by demonstrating a mapping between our model and Drools syntax compatible with an existing gamification engine. In particular, we illustrate how to ease the implementation of quests and challenges by using an example from an existing gamified system in the sustainable mobility domain.

    Designing mixed media artefacts for public settings2004In: Cooperative Systems Design. Scenario-Based Design of Collaborative Systems / [ed] Darses, F., Simone, C. and Zacklad, M., Amsterdam: IOS Press , 2004, p. 195-210Conference paper (Refereed)
    Abstract [en]

    This paper describes how principles which are emerging from socialscientific studies of people’s interaction with mixed media artefacts in public place have been used to support the development of two installations, the second of which is a long term museum exhibit. Our principles highlight the design of ‘emergent collaborative value’, ‘layers of noticeability’ and ‘structures of motivation’ to create an ‘ecology of participation’ in installations. We describe how our first installation was used as a ‘research vehicle’ that guided and shaped the design of the museum installation. We also provide an account of how people interact with our installations and how this analysis has shaped their design. The paper closes with some general remarks about the challenges there are for the design of collaborative installations and the extent to which we have met them.

    Katana databas 1.02009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The task to this thesis has been to create an application, Katana-databas 1.0, for analysing c-code. The generated output gets stored in a data structure which content in the end of the program run gets written in a textfile which gets used by Katana. It's a tool for reverse engineering, developed by Johan Kraft at Mälardalens institute.

    Katana-databas has got the following limitations. (1) It can only handle preprocessed files, meaning it doesn't contain any rows beginning with "#". (2) Only complete files can be handled. (3) No references to unknown functions or variables are allowed. (4) A further limitation is that the application can't handle any ADT's. It can only handle primitive types. (5) Finally the application is only written for pure c-code, and thus doesn't handle code written C++.

    The task has been solved by creating an automatically generated lexer with Flex and Bison rules in Visual Studio. There after a limited parser has been developed which purpose is to process the lexemes which the lexer generates.

    The underlying causes for the thesis is to replace Understand with Katana-databas. Katana has this far used the database in Understand, but it contains closed source code. What is seeked is open source code, which Katana-databas is based on.

    Management and Information Technology after Digital Transformation2021Collection (editor) (Other academic)
    Abstract [en]

    With the widespread transformation of information into digital form through-out society - firms and organisations are embracing this development to adopt multiple types of IT to increase internal efficiency and to achieve external visi-bility and effectiveness - we have now reached a position where there is data in abundance and the challenge is to manage and make use of it fully. This book addresses this new managerial situation, the post-digitalisation era, and offers novel perspectives on managing the digital landscape. The topics span how the post-digitalisation era has the potential to renew organisations, markets and society. The chapters of the book are structured in three topical sections but can also be read individually. The chapters are struc-tured to offer insights into the developments that take place at the intersection of the management, information systems and computer science disciplines. It features more than 70 researchers and managers as collaborating authors in 23 thought-provoking chapters. Written for scholars, researchers, students and managers from the manage-ment, information systems and computer science disciplines, the book presents a comprehensive and thought-provoking contribution on the challenges of man-aging organisations and engaging in global markets when tools, systems and data are abundant.

    Business Intelligence som del i skapandet av konkurrensfördelar2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Problem: When business leaders around the world are about to take a decision, 40% of these decisions are based on gut rather than any rational information. This, together with the claim that “one of the biggest hinders for competitive advantage is acting solely on gut or intuition” leads to the combination of the decision support tool Business Intelligence and competitive advantage. Competitive advantage can be seen from numerous perspectives; one of these is the resource-based view, where the resources are the basic pillar for competitive advantage. From this the thesis study question is formulated; “How and why can BI, seen from a resource-based perspective, support the creation of competitive advantage, on short and long term, in large companies?

    Purpose: To explain and describe how and why BI, seen from a resource-based perspective, can support the creation of competitive advantage, on short and long term, in large companies.

    Theory: The theoretical foundation is based upon definitions on BI and what BI really is, together with a presentation and discussion on the resource-based view. Following the BI and resource-based view parts, the research model for this thesis is presented, where a modified resource-based view model for competitive advantage, and a definition collection for BI, is combined.

    Method: For this thesis, 18 companies where they have some sort of BI solution implemented, has been interviewed. The companies have been selected based from their size, where the 120 largest companies first were contacted with an interview proposal. The companies are based in industries such as media, telephone communications and insurance. On these companies, the individual that is the “BI responsible” has been interviewed, which varies from company to company. BI responsibles could be Controllers, IT Managers or specific BI Managers.

    Conclusions: In the conclusions part of this thesis the research question is divided into a how part and a why part. One conclusion from the how part, is that BI can both support and drive a so-called patching capability, which means that a company can be faster and more agile in their market adaption. One of the reasons why BI can support competitive advantages from a resource-based view is that it can help to drive efficiency, optimization and process innovation in different capabilities that can lead to competitive advantage. Another conclusion is that despite its abilities to support what drives competitive advantage through the resource-based view, the term for this is mainly short-term, due to the fact that it is not hard to imitate the information, which constitutes the basic resources that BI supports.

    System Design for Import and Export of Classified Information Over Less Secure Systems2023Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to define a secure system design for reducing the security classification of a document. A reduced security classification makes it possible for the document to traverse an intermediate system with lower security measures before reaching a system with sufficient security measures to manage the original document.

    A pressing requirement for companies and governments to secure their digital assets arises with the digitization of societal functions and the continuously escalating tensions in world politics. Digital security as a software implementation is no longer sufficient due to the ongoing race between digital offense and defense. It has become imperative for security to be an integral consideration at every stage of system design, such that it is implemented in a manner that prevents software from being transformed into a liability.

    In Sweden, actors in both the private and public sectors that are deemed of national importance are required to comply with several laws and regulations if they possess an IT system. A key principle in most of these regulations is the requirement for military-approved signal protection if an actor intends to transmit classified information through an intermediary system that does not conform with the system´s implemented security measures.

    Our design proposes using an information manager and a secret sharing scheme, the contents of the original document are encrypted in such a way that no decryption key is required while still achieving information-theoretic security. We can ensure integrity and confidentiality by using a dual-diode configuration for import- and export systems. This implies that as long as an antagonist does not have the resources to eavesdrop on all communication, the integrity and confidentiality of the sending and the receiving systems, as well as the transported document, can be ensured.

    Informationsmaterial till kopparverket i Riddarhyttan2008Independent thesis Basic level (degree of Bachelor), 15 points / 22,5 hpStudent thesis
    Abstract [sv]

    Den här rapporten innehåller information om hur jag har gått till väga i mitt examensarbete, som har bestått i att utforma två broschyrer och tre skyltar till ett kopparverk i Riddarhyttan. I rapporten redogör jag för hur jag har gått tillväga vid utformningen av mitt arbete, de teoretiska utgångspunkterna som ligger till grund för utformningen samt det slutgiltiga resultatet.

    Bakgrunden till uppgiften är att den befintliga broschyren är, enligt min uppdragsgivare Mona Kärner Eliasson, väldigt jobbig att läsa med svåra facktermer och dåligt utförd layout. De har även tidigare funnits ett skyltsystem som de var tvungna att ta ned för att det var i dåligt skicka och det var även svårt att förstå och hänga med i texterna.

    Vid utformningen av de nya informationsmaterialen har jag både utgått från min uppdragsgivares önskemål så väl som de teoretiska erfarenheterna som jag har fått från böcker och min utbildning inom informationsdesign. Jag började med att titta på broschyren som redan fanns på plats vid kopparverket, och därefter inledde jag mitt arbete med att söka information om och bilder på kopparverket. Jag ringde även runt till olika myndigheter för att få mer information om vilka lagar och regler jag var tvungen att följa i mitt arbete. Jag sökte i olika litteraturer för att få mer kunskap om hur man utformar lättlästa och effektiva budskap. Därefter började mitt arbete med att utforma informationsmaterialen. Under arbetets gång gjorde jag tre utprovningar, en på vardera broschyr och en på skyltarna. Därefter skedde förändringar där det behövdes, innan informationsmaterialen var färdiga.

    Vägarna mot en integrerad IT-infrastruktur2008Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Problembakgrund:

    Företag investerar bl.a. i affärssystem (ERP-lösningar) för att dra nytta av de fördelar systemen förväntas leverera i form av bättre beslutsstöd och effektivare processer vilka är viktiga för att företag skall uppnå en högre nivå av konkurrenskraft och tillväxt. I grund och botten av alla fungerande IS (Informationssystem) ligger en nödvändig integration mellan verksamheten samt deras IT-infrastruktur, vilken är nödvändig för förverkligandet av de nyss nämnda fördelarna. Integrationen mellan verksamheters IT-infrastruktur kan vara komplex och svår att erhålla. ERP-lösningar består av moduler för verksamhetsspecifika funktioner vilka rent hypotetiskt möjliggör en fullständig integration genom standardisering. ERP-system är en lösning på detta integrationsproblem, men andra lösningar finns vilka är baserade på integrationsverktyg för integrering av befintliga arvssystem och även nya. Det är denna integrationsproblematik och ett genuint allmänt intresse för affärssystem som lett till att uppsatsens fokus lagts på att undersöka hur verksamheter uppnår en integrerad IT-infrastruktur.

    Problemspecificering:

    Hur kan verksamheter uppnå en integrerad IT-infrastruktur?

    Syfte:

    Syftet med uppsatsen är att beskriva och analysera hur verksamheter går tillväga för att uppnå en funktionellt integrerad IT-infrastruktur.

    Metod & tillvägagångssätt:

    Inledningsvis genomfördes en granskning av befintlig tidigare forskning inom området, för att ett underlag till den teoretiska referensramen som presenteras i denna uppsats skulle erhållas. Denna gav i sin tur upphov till konstruktionen av frågeformulären som användes vid insamlandet av det empiriska materialet.

    Tidigare forskning:

    Den tidigare forskningen kring integrering av IT-infrastruktur är riklig och huvuddelen av forskningen tycks fokusera på ERP-system levererade från en och samma leverantör. Detta kan vara en lösning eller metod som passar många företag, men långt ifrån alla. EAI är en metod som går ut på att arvssystem länkas samman med modernare system och därigenom hypotetiskt löser integrationsproblematiken.

    Best-of-Breed (BoB) är en lösning som i dagsläget med funktionsmässiga samspel mellan ERP och EAI har visat sig vara ett intressant integrationsalternativ. BoB innebär att moduler från olika leverantörer implementeras sida vid sida. Företag som erfordrar specifika lösningar kan med fördel vända sig mot implementering enligt BoB principen, förutsatt att en integration kan verkställas. BoB har sina fördelar och nackdelar, en fördel är bl.a. att företagen får möjlighet att forma ett system som passar just deras önskningar och behov. En nackdel är integrationssvårigheter mellan delsystemen (modulerna) som måste lösas genom exempelvis integrationsverktyg. Även dubbellagring av data kan vara ett problem då data bli utspridd på flera databaser.

    Resultat:

    I och med denna uppsats undersökning framkommer det att verksamheter med fördel kan integrera funktioner för kärnverksamheten med hjälp av ett ERP-system. Detta blir extra avgörande om företaget tillverkar varor. Tjänsteproducerande verksamheter kan däremot med sina specifika krav och behov integrera befintliga eller nya IT-lösningar via integrationsmotorer.

    Förutsatt att en öppen standard får fotfäste som byggsten för integrationsprodukter kan BoB-lösningar möjligen komma att framföras som ett bra alternativ till att uppnå en integrerad IT-infrastruktur.

    Title                    ERP-solutions in small to medium sized enterprises – possibilities and problems

    Summary          ERP-solutions have penetrated the market for SME: s, offering the same advantages larger enterprises have enjoyed for years. For a significantly cheaper price, SME: s can nowadays acquire ERP-solutions and become more effective and increase their profit.  The authors have examined five SME: s in both the production and service company segment and have come to the conclusion that an ERP-solution would indeed benefit these companies in many levels but also induce certain obstacles the examined companies must overcome, both financial and organizational.

    Purpose            The purpose of this thesis is to examine if and how SME: s can become more efficient and developed and increase their profit by implementing an ERP-solution. Further, the purpose is to discuss which conditions that exists for the examined SME: s in order to implement an ERP-solution.

    Method            The thesis consists of a qualitative research where the authors have interviewed either the owner or employees at management level by using semi-structured interviews. The results from the interviews have been analyzed based on the theoretical framework.

    Result                Several improvement areas have been identified, most typically the processes are lacking efficiency in some areas even if the SME already had an ERP-solution (or similar) or did not have one at all. Most SME: s did lack the financial resources required for an ERP-solution deployment.

    Conclusion      The findings show that there are development possibilities within the examined SME:s. The biggest revenue improvement would be decreased manual labor and improved processes. An ERP-solution would help the SME: s achieve that since it automates many tasks and are designed with “best practices” in mind. Despite most of the SME:s lacking financial resources for an ERP-solution, there were some exceptions which contradicted the theoretical framework, mainly because they were SME: s but acted under a larger owner/franchise chain.

    Designing for Workplace Safety: Exploring interactive textiles as personal alert systems2020In: TEI'20: Proceedings of the fourteenth international conference on tangible, embedded, and embodied interaction, 2020, p. 53-65Conference paper (Refereed)
    Abstract [en]

    Despite various safety regulations and procedures, work accidents remain a significant problem in the global process industry and the Swedish steel industry. To address personal safety and safety culture, wearable alert systems were prototyped and tested with steelworkers in iterative workshops. A resulting design concept, in the form of an interactive textile patch worn on the protective gear, suggests a simple way of transmitting personal alerts using light. A crucial design factor identified is to enable the communication between workers and peers as well as communicating with control room staff. The visual design can positively influence the acceptance of the patch, but its impact on the safety culture cannot yet be assessed. The present study contributes by approaching workplace safety and culture with a new design concept of IoT and e-textile technologies based on the interaction modalities of light, sound, and vibration.

    SERVICE-ORIENTED ARCHITECTURE: AN INNOVATION PROCESS PERSPECTIVE2007Doctoral thesis, comprehensive summary (Other scientific)
    Abstract [en]

    In traditional information systems for the grocery retail trade, the different parts are strongly dependent of each other. Should one function change, the whole system must be rebuilt which is expensive and time consuming. The result is that many necessary process improvements are never done. Case company, a Nordic retail software vendor, in 2004 summarized what they regarded as a ‘cul-de-sac’. Building distributed store systems in which the same data appears in several places, creates a complexity which increases with new functions and which eventually becomes obstructive.

    The aim of this thesis is to attain a deeper understanding of service-oriented architecture (SOA) in order to increase and maintain personal treatment of the customers, while fulfilling business demands of changes and integration in enterprise systems. The aim is operationalised by one overall research question and seven sub-research questions.

    To answer the research questions, a longitudinal case study and a survey study were performed. Innovation theory is applied to the SOA adoption process.

    This thesis is composed of a series of seven articles, through different perspectives, with an innovation diffusion approach. The first offers lessons learned by a retail software provider and the role of the customer. The second article states SOA is to be a driver for personalization, i.e. different customers are treated differently. The third is about SOA being a driver for distributed decision support. The fourth describes a study on how to measure the effects certified solution architects have on business. The fifth article deals with enterprise architecture frameworks in practice. The sixth is mainly a literary study describing SOA maturity models. The sevenths article is devoted to a review of why the case company chose SOA as a foundation for their new generation of retail systems.

    SOA must show compatibility with existing mission critical systems, or the adoption may be blocked. Reinvention of the architectural framework eases SOA adoption.

    Implications for practice, is discussed, outlining, both, the great risks and the great opportunities. This thesis states that business driven SOA helps to manage full business processes and permit access to in-house and external systems.

    Automated Data Visualizations  – A Modular and Extensible Approach2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Data analysis is an area that has evolved greatly in recent years where focus has been on the automation of many of its processes. Processes such as data extraction and data processing have been successfully automated using many different approaches but the process of automatically constructing informative data visualizations has not received the same attention. This thesis has been performed in cooperation with Scania AB. The purpose of the thesis is to examine how the data visualization process can be automated through the use of decision trees to convey integration test results. This was done by investigating Information Visualization principles, and developing a data analysis tool capable of performing both manual and automatic data visualization. The functionality of the tool was influenced by feedback received when conducting interviews with Scania employees experienced in data analysis, while information visualization principles were used as a basis when developing the expert system responsible for automatically generating charts. The thesis resulted in a working prototype, capable of automatically extracting, processing and visualizing data from Jira. The results of the thesis show that it is possible to automatically generate informative visualizations with the use of decision trees, and that the generated visualizations may be able to be effective at displaying integration test results.

    Valet av affärssystem: framgångsfaktorer under upphandlingsfasen samt förväntade effekter av affärssystem2008Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Att införskaffa ett nytt affärssystem är en stor investering för en organisation. Den höga komplexiteten av ett affärssystemprojekt samt de kostnader, både tidsmässiga och monetära, associerade med projektet gör att många företag undviker att påbörja ett affärssystemprojekt. För att underlätta för organisationer som vill införa ett nytt affärssystem finns det konsulter som kan hjälpa till under affärssystemsprojektets alla faser. Denna uppsats fokuserar på upphandlingsfasen och de framgångsfaktorer som bör beaktas under upphandlingsfasen av ett affärssystem. Uppsatsen tar hjälp av upphandlingskonsulten Medius AB för att identifiera och utvärdera framgångsfaktorer under upphandlingsfasen. Intervjuer utföres även med kunder till Medius AB för att få deras syn på upphandlingsfasen och viktiga framgångsfaktorer däri. Förutom framgångsfaktorer under upphandlingsfasen undersöker uppsatsen även motiven till att företag väljer att införskaffa affärssystem, de effekter som kunder till Medius AB förväntar sig av det nya affärssystemet. Studien visar att det finns framgångsfaktorer som kan sägas vara extra viktiga under just upphandlingsfasen och som bör beaktas för att affärssystemsprojektet ska lyckas. Dessutom visar studien att mätbara effekter av affärssystem såsom till exempel minskade produktionskostnader inte är orsaken till varför de studerade företagen valt att införskaffa ett nytt affärssystem. Det är istället omätbara effekter såsom ökad flexibilitet inom företaget och en ökad kundnöjdhet till produkt och service som är anledningar till att de studerade företagen valt att införskaffa ett nytt affärssystem.

    Evenemangsbeskrivningar utformade enligt god informationsdesign åt Sundbyholmstravbana2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Vi har skapat en broschyr och evenemangsbeskrivning enligt god informationsdesign åt Sundbyholms travbana. De ska användas för att utöka deras målgrupper. I vårt framtagande av det grafiska materialet har vi följt de riktlinjer som finns för god informationsdesign. De har vi gjort genom att vi skapade texter och layout som har god läsbarhet, läslighet, läsvärde och läsbehag. Vi har även tänkt på de riktlinjer som finns för radlängd vilket innebär att det inte överstiger 70 tecken. Teckensnittsvalet har vi anpassat så att de ska vara lättläst.

    Att målgruppsanpassa varje evenemang utefter målgruppen är det som vi strävade efter. Det var svårt att genomföra i praktiken då vi hade skilda målgrupper att anpassa oss efter. Vi valde istället att göra ett material som genomgående tilltalar alla i målgruppen.

    Vi skapade en röd tråd i vårt material genom att använda färgkodning, ha samma bilder och teckensnitt i både broschyren och evenemangsbeskrivningarna.

    Genom intervjuer, enkät och utprovningar fick vi fram vad som attraherar målgruppen. Genom att följa resultaten har vi skapat ett målgruppsanpassat material som följer de riktlinjer som anses vara god informationsdesign.

    Title Business-to-Business IT Integration

    Introduction

    As business world has moved into digital era, new trends in business models have been emerged to do business. Digital infrastructure provided by internet enables enterprises to extend their boundaries for new customer and trading partners. Extending the enterprise without a solid IT infrastructure is incomplete, this is the reasons that enterprises are investing more and more in IT to build an IT integrated infrastructure where all its trading partners are linked together. On the other hand, technological world provides solutions and services to build IT integration for such extended enterprises. A wide variety of IT integration solutions and patterns available for enterprise to meet their integration goals, but this often brings unclear situation where companies have to think a lot before implementing IT integration patterns. A slight mistake in this scenario could shake the equilibrium between IT and business, to keep the equilibrium steady companies need to thoroughly examine their short-term and long-term goals and then different integration patterns can be employed to meet these goals.

    Research Question

    What approaches can be helpful for companies to accomplish successful business-to-business IT integration pattern for their short-term and long-term goals?

    Purpose

    The purpose of this thesis is to describe the concept of extended enterprises and, identify and describe the existing B2B IT integration approaches employed by extended enterprises.

    Method

    The research is of qualitative type and secondary data is used to conduct this research. Books and research papers has been used to construct theoretical framework. Electronic databases available at library of Mälardalen University such as Google scholar, Emerald and interlibrary network of Sweden (Libris) are used to search for secondary data.

    Analysis Findings from the detailed literature study are analyzed to answer the research question. Integration patterns are analyzed described by the different authors of integrations patterns in three different ways. Firstly, integration patterns were analyzed in term of their advantages and disadvantages with technology and business, secondly, maturity of these integration patterns are analyzed and finally these integration patterns are analyzed for company’s short-term and long-term goals.

    Conclusion Business process oriented and method-oriented approaches are good for long-term goals due to handling of business process management in both approaches and reusability aspects of method oriented approach. For short-term goals portal-oriented approach dominating in the integration community, application interface oriented approach is also good to meet the short-term goals. However, combinations of different approaches are found feasible.

    CRM-systems påverkan på företag och dess kundrelationer2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This research is about how the usage of a CRM-system (Customer Relationship Management) affects companies and its customer relations. Other researches show that CRM-systems can give big advantages for both the customers, companies and the relations in-between. But there are many issues that affect how much a CRM-system change the relations between companies and its customers. The result from this research could be of interest for a company which is thinking about implementing a CRM-system or improve one they already use. Which leads us to our research question: How does CRM-system affect companies and their customer relations?

    The purpose of this thesis is to describe and analyze how a CRM-system affects companies and their customer relations.

    The research is based on a theory framework that gives an insight into what relations are and of what significance customer relations have for a company, also CRM-systems is discussed and their effects on companies. The collected theory concludes with a research model that begins with a CRM-system and shows how it according to the theory framework could affect a company and its customer relations. This model is used as the foundation in the collection of the empirical information.

    The study began with a literature study that resulted in a research model. We performed six interviews at four companies that use CRM-systems. Then with help from the research model we analyzed the answers from the interview and created the result and conclusions.

    In the thesis it’s established that the examined companies don’t use the CRM-systems full potential. A centralized database is one of the most important CRM-system components in a company’s strive for better customer relations. The research concludes with a list of the factors we consider being of weight for a company that wants to know how a CRM-system could affect companies and their customer relations. If a company use its CRM-system in the right way they can get both better customer service, individualized services, improved information management and increased customer loyalty which all contributes to better customer relations and gives companies competitive advantages.

    Thesis Web Dialogue2007In: European Journal of Open, Distance and E-Learning, E-ISSN 1027-5207, no 2Article in journal (Refereed)
    Abstract [en]

    This paper describes development work where an application specially adapted for essay-writing and supervision has been constructed, developed and tested. The aim of the programme development has been to create support for essay-writing and supervision. With the ambition of reinforcing important ingredients for effective supervision and essay-writing the aim and requirements for the Thesis Web Dialogue were formulated. The chief aim from the tutor's perspective was to facilitate organizing his or her supervision and efficiently follow and support the essay-writer. The essay-writers' chief aim was to find easy access to tutor support and information relevant to their essay work. The Thesis Web Dialogue was continuously developed and evaluated, a process which culminated on two evaluation occasions. The majority of the tutors and essay-writers who had tested or been introduced to the Thesis Web Dialogue are positive to its idea and function. The most positive is the student group. A few students have expressed their scepticism vis-à-vis the Thesis Web Dialogue. Some of these students feel uncertain when confronted with the technology, while some apparently want to avoid be subjected to higher demands and greater insight into their essay work. The result shows that the Thesis Web Dialogue can be of great help to many students and tutors. It is probably especially suitable for distance courses and/or essay courses where the tutor follows the essay writers for a fairly long time.

    The Online Presence of Non-Profit Cluster Organizations: A Study on Automation Region's use of the Internet2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction

    This paper focuses on the Internet and more specifically on how non-profit organizations can use the Internet to enhance their online presence. Our choice of research object is Automation Region (AR), a non-profit cluster organization, whose purpose is to strengthen and make the cluster of companies within industrial automation in Mälardalen visible. This cluster consists of business-to-business companies in the automation industry and AR was formed to increase the productivity, growth and profitability of these companies. The organization has two goals set up, which include: (1) increased exposure for the automation industry as well as the region wherein AR operates and (2) attracting the best competence as well as getting youths and children interested in automation. AR currently has a website (www.automationregion.com) and the overall purpose for it is to support AR's goals. However, we have a difficulty seeing how this website, as it looks and functions today, is to achieve the goals and objectives of the cluster organization and we also find it difficult to see how AR should do in order to expose its website and its brand to its target audience. The two research questions then becomes: How is Automation Region's website being used today? How can Automation Region utilize the Internet to achieve its goals?

    Purpose

    The purpose of this study is to gain a deeper understanding of how cluster organizations like Automation Region may use the Internet to achieve its goals, and by doing this also be able to give recommendations on how Automation Region can benefit from the use of the Internet as their primary channel for goal achievement.

    Method - An Action Research based study

    This paper is based on an action research approach, which contains a real world problem, a framework of ideas, and a set of methodologies. The different means of collecting data used in this paper can be categorized in four separate categories: interviews, internet analysis tool, benchmarking, and other empirical data collected.

    Framework of ideas

    Our framework of ideas consists of an introduction to the term clusters, which then explains the different actors on the cluster stage. Then the benefits of clusters are discussed, leading to a further discussion on how non-profit cluster organizations can utilize the possible benefits of a cluster. This leads to a presentation of different ways to improve an organizations online presence.

    Analysis

    The analysis is divided into two parts. The first part focuses on the results of the website analysis, where different reports from the web analysis program are analyzed. This will show how the website currently is being used and should lead to conclusions on how this usage can be improved. The second part focuses on the available Internet tools and how AR can utilize these to reach their explicit goals for the cluster organization.

    Conclusions

    The so called internal visitors are plentiful on AR's website site and we can conclude that the site is being used in an Intranet like way. Another conclusion is that AR should be able to increase the probability of achieving their goals by further enhancing the use of the Internet tools they currently have (website and e-mail), and also by expanding their online presence with the use of several other potential Internet tools.

    Vision based facial emotion detection using deep convolutional neural networks2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Emotion detection, also known as Facial expression recognition, is the art of mapping an emotion to some sort of input data taken from a human. This is a powerful tool to extract valuable information from individuals which can be used as data for many different purposes, ranging from medical conditions such as depression to customer feedback. To be able to solve the problem of facial expression recognition, smaller subtasks are required and all of them together form the complete system to the problem. Breaking down the bigger task at hand, one can think of these smaller subtasks in the form of a pipeline that implements the necessary steps for classification of some input to then give an output in the form of emotion. In recent time with the rise of the art of computer vision, images are often used as input for these systems and have shown great promise to assist in the task of facial expression recognition as the human face conveys the subjects emotional state and contain more information than other inputs, such as text or audio. Many of the current state-of-the-art systems utilize computer vision in combination with another rising field, namely AI, or more specifically deep learning. These proposed methods for deep learning are in many cases using a special form of neural network called convolutional neural network that specializes in extracting information from images. Then performing classification using the SoftMax function, acting as the last part before the output in the facial expression pipeline. This thesis work has explored these methods of utilizing convolutional neural networks to extract information from images and builds upon it by exploring a set of machine learning algorithms that replace the more commonly used SoftMax function as a classifier, in attempts to further increase not only the accuracy but also optimize the use of computational resources. The work also explores different techniques for the face detection subtask in the pipeline by comparing two approaches. One of these approaches is more frequently used in the state-of-the-art and is said to be more viable for possible real-time applications, namely the Viola-Jones algorithm. The other is a deep learning approach using a state-of-the-art convolutional neural network to perform the detection, in many cases speculated to be too computationally intense to run in real-time. By applying a state-of-the-art inspired new developed convolutional neural network together with the SoftMax classifier, the final performance did not reach state-of-the-art accuracy. However, the machine-learning classifiers used shows promise and bypass the SoftMax function in performance in several cases when given a massively smaller number of samples as training. Furthermore, the results given from implementing and testing a pure deep learning approach, using deep learning algorithms for both the detection and classification stages of the pipeline, shows that deep learning might outperform the classic Viola-Jones algorithm in terms of both detection rate and frames per second.

    Supervised machine learning techniques to protect IoT healthcare environment against cyberattacks2023In: Intelligent Edge Computing for Cyber Physical Applications, Elsevier , 2023, p. 17-34Chapter in book (Other academic)
    Abstract [en]

    The Internet of Things (IoT) have become the central technology of the current years. Almost all industries are amalgamating the IoT in their production to enhance the outcome of their businesses. Healthcare organizations, in particular, are taking advantage of the services provided by the IoT, known as the Internet of Medical Things (IoMT), to enhance the healthcare systems by moving from manual management systems to computerized systems professional storage. Connecting doctors, nurses, and patients for information exchange is the aim of applications on mobile devices. Thus all collected data is stored in healthcare storage systems. Since cyberattacks on healthcare systems are overgrowing, creating robust systems to secure patients’ confidential information is crucial. This chapter includes a deeper understanding of the integration of IoT in health informatics and medical services. It introduces supervised machine learning techniques for health datasets showing how machine-learning techniques help in increasing the healthcare system’s security by discovering attacks and analyzing their behaviors. The results obtained from this study are compared and discussed in this chapter with the results of previous research works. Finally, some future challenges and studies related to the contribution of IoT security in the health informatics and medical services fields are proposed.

    Abstract [en]

    The thesis report investigates the important steps related to the decision making of IT

    outsourcing. Mostly organizations do not achieve their expected goals from IT outsourcing

    due to the complexity of decision making process. The main purpose of this thesis, thus, is to

    describe the necessary steps of IT outsourcing decision making, reveal both major reasons for

    taking such a decision and main risks involved with it. As secondary data source, books and

    some previous research papers on the issue have been used in order to give better

    understanding of the thesis topic. To collect relevant empirical data, a questionnaire was sent

    to a range of Swedish and Pakistani companies. The thesis report shows that, a successful and

    effective IT outsource decision requires a clear vision of the issue and of the effects that such

    a decision may bear with it.

    Abstract [en]

    Thesis Purpose

    Examine the possibility of small IT companies being benefited from a Cloud Computing transition. Through one case study of a software development company and interviews from five Hallstahmmar’s IT companies, we showed how Cloud Computing can enable organizations to decrease IT investments and related costs. Besides we critically analyzed some drawbacks of this latest concept.

     

    Methodology

    Primary and secondary data has been collected based on a qualitative method and a structured approach. The collected material of the secondary data was mainly based on latest journals. The interviewing parts have been recorded and summarized.

     

    Theoretical Perspective

    We have used theories of various aspects of business related to Cloud Computing; e.g. innovation and Cloud Computing, business model and Cloud Computing in order to acquire a complete knowledge base for analyzing our empirical data.

     

    Empirical Foundation

    A case study of TotalAssist, interview data of LifeCenter AB and interviews of four IT companies of Hallstahammar, are our empirical foundation of the reserach.

     

    Conclusion

    IT companies of Hallstahammar may adopt the Cloud Computing paradigm. Besides, yet this new concept has its risks. Security remains a concern among many CIO’s. In addition, we recommend means that a company can pursue while implementing a Cloud Computing transition.

    Privacy by Design Principles in Design of New Generation Cognitive Assistive Technologies2016In: ICT systems security and privacy protection: 31th IFIP TC 11 International Conference, SEC 2016, Hamburg, Germany, May 30-June 1, 2016, Proceedings / [ed] Jaap-Henk Hoepman & Stefan Katzenbeisser, Springer , 2016, p. 384-397Conference paper (Refereed)
    Abstract [en]

    Today, simple analogue assistive technologies are transformed into complex and sophisticated sensor networks. This raises many new privacy issues that need to be considered. In this paper, we investigate how this new generation of assistive technology incorporates Privacy by Design (PbD) principles. The research is conducted as a case study where we use PbD principles as an analytical lens to investigate the design of the new generation of digitalized assistive technology as well as the users’ privacy preferences that arise in use of this technology in real homes. Based on the findings from the case study, we present guidelines for building in privacy in new generations of assistive technologies and in this way protect the privacy of the people using these technologies.

    Automotive Service-Oriented Architectures: a Systematic Mapping Study2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Service-oriented architecture is a possible solution to the increasing complexity of automotive software systems. We conduct a systematic mapping study investigating the use of service-oriented architecture in automotive software. This study aims at providing information on publication trends, available architectural solutions, main benefits and challenges in automotive service-oriented architecture. From an initial set of 341 peer-reviewed publications, we selected 28 primary studies, which we classified and analysed using a thorough protocol. We provided both quantitative and qualitative analyses using vertical and orthogonal analysis. We found that there has been a significant increase in the number of publications recently, and that the studies focused on defining functionalities and data flow between them. Functionality was found as the most recognized benefit when applying service-oriented architecture in the automotive domain, while security, safety and reliability are the most recognized challenges.

    Business Intelligence-system och deras inverkan på rationellt beslutsfattande: En studie på två företag2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In all kinds of organizations decisions have to be made and if an organization is to succeed, the ability to make the right decisions is of uttermost importance. When it comes to decision-making the so called rational decision model, in which decision-makers are assumed to possess the necessary information in order to make the correct decisions in accordance with the organizations overall objectives, has been one of the most popular among economists. However, this view has been criticized and said to be inadequate when real decisions in real organizations are to be made, and that the rationality is bounded. There are, however, those who are of the opinion that these limitations can be overcome by computer-based decision-support systems in order to make rational decisions, and, in addition, that these systems can provide the information necessary for making quick and accurate decisions. One such decision-support that has gained popularity during the last decade is the business intelligence system (BI system). In this thesis we want to investigate what impact BI systems may have on rational decision-making, and, in addition, how these BI systems may be composed. Hence, our research questions are:

    • How may companies' BI systems be composed?
    • What impact do BI systems have on decision-makers ability to make rational decisions?

    Hence, the purpose of this master thesis is to describe how companies' BI systems are composed and analyze the impact BI systems have on decision-makers ability to make rational decisions.

    The focus in this thesis's framework of ideas is on rational decision-making and general ideas concerning BI systems and their components. These sections are then merged into a research model which is used in order to analyze the results of the study that constitute the foundation of this thesis. The method used in this study is interviews at two companies (SNA Europe and KG Knutsson AB), and the interviewees are persons that use BI systems in their everyday work as a support in their decision-making. We have also interviewed persons from each of the companies' IT depart­ments in order to understand the structure and technical functionality of each of the companies' BI system.

    When it comes to the composition of the BI systems we have been able to come to the conclusion that they vary quite a bit, depending on the overall IT infrastructure of the company. This does not induce any differences worth mentioning regarding the two companies' use of their BI systems, since the decisions supported and the data used in order to make these decisions are practically the same regardless of company. We have also noted that the easier it is to access information the more the BI system is used. Another conclusion is that company IT infrastructures including several legacy-systems tend to have a more traditionally composed BI system. Regarding the impact on rational decision-making we have been able to come to the conclusion that BI systems improves the rationality concerning decisions based on quantifiable data that are easily measured. These more simple decisions have turned out to be, if not completely rational, at least very close to being rational. We have also seen that when the conditions in which decisions are being made are more complicated, the BI systems at least have some positive effect on the rationality of the decisions. Above all, the BI systems can provide the decision-makers with the information necessary to make more objective, informed decisions and by doing so reduce the limitations of the rationality.

    Individers upplevelser av en IT-relaterad förändringsprocess: En fallstudie på Nordea2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background/Problem

    The subject of change has been frequently discussed in the research field of organization theory, for instance the importance that those individuals that are outermost affected by the change in question are properly informed about it and the benefits that it will bring about, along with the involvement of these employees in the process of change in order to avoid skepticism and worry. Nordea Bank AB is introducing a new information system in all of its Swedish offices, in the shape of a new cash desk system: Teller. It is our intention to, by performing a case study at a number of Nordea offices, describe how individuals experience an information technology (IT) related change and to analyze what affects the experiences of individuals during the preparations, implementation and the work carried out after the implementation of an IT related process of change.

    Purpose

    The purpose of this study is to describe and analyze how a process of change, regarding the cash desk system of a bank, is experienced by the individuals that are outermost affected by it.

    Method/Theoretical framework/Analysis

    By studying existing theories concerning IT and organizational change, we have created an interview guide, which has been the foundation on which the empirical study has been conducted. The study in question consists of a case study which includes three Nordea offices where we have conducted interviews with members of the offices’ staff, more specifically staff members working at the cash desk and/or the customer service. The theoretical model that has been the foundation of this analysis is Lewin’s model for organizational change, where a process of change is divided into different phases for the preparations, the actual change and the work following the change. From analysis between theory and empirical results, conclusions have been drawn about how individuals experience an IT related change along with what it is that affect these individuals’ experiences through the process of change.

    Conclusions

    One conclusion that we have been able to draw is that the training has had a great impact on how individuals, in this case the users of a new cash desk system, experience an IT related change. This goes for both the training material as well as how well the local change management has followed the existing training guide lines. Furthermore it has been shown that persons acting as a support on the day of the implementation of the cash desk system, is something that was highly appreciated by the individuals. This due to the anxiety of not being able to conduct one’s work tasks as well as before the change in question, which often comes with IT related changes. When it comes to ending the change we have been able to see that, to prevent a regress to old habits and ways of thinking, it is important to see to the problems and questions that arise during the process of change.

    Title: Managing IT-incidents, a case study at ICAs IT department                            Operations

    Keywords: IT-incident management, IT-incident management process, IT-incident, ITIL, CCTA

     

    Problem: An organization can benefit by having an established management process of handling IT-incidents. But how can this be achieved? Are there step-by-step procedures? What´s included in the management process of IT-incidents? Is the size of the organization relevant to which model is to be chosen? Can the work of the writers of this essay result in a recommendation of a specific model for IT-incident management? These questions lead to the following essay question; How are IT-incidents managed?

    Purpose: The purpose of this thesis is to describe and discuss how IT incidents can be managed.

    Method: The writers of this essay have performed a case study at ICA, a Swedish food retail company. Eleven interviews with nine different persons have been carried out. The interviews are analyzed in the chapter called Resultat och analys.

    Conclusion: Our conclusion is that there are both similarities and differences in Dept. Operations´ management process for handling IT-incidents compared to what is stated in the CCTA-model. Another conclusion is that it is of highest importance for a business to implement a standard procedure for handling IT-incidents. The lack of such a model could result in e.g. financial losses.

    Title: A study about the purchasing process of IT

    Level: Master thesis in Information Technology and Business Administration, 15 hp, EIK024

    Authors: Emelie Johanson and Mikael Lindström

    Tutor: Peter Ekman, Mälardalens Högskola

    Keywords: IT-investment, purchase, decision

    Problem: In the last decades the amount of IT investments increased and has become an important resource within most organizations. IT gives the ability to compete and could also be a condition for many to be able to compete. In different businesses it could vary in where they put their focus when they choose an IT investment. This thesis examines how the purchase process of IT looks. How does processes differs in a bigger company versus a smaller company? From these two perspectives this study examined these research questions: Who makes the decisions whether or not an IT solution should be purchased? What aspects decide when companies are to choose between different IT solutions? Where in the purchase process do problems usually emerge?

    Purpose: The purpose of this thesis is to describe and analyze the purchasing process of IT from a business perspective. The purpose is also to see if it differs in a bigger company versus a smaller company and where the problems usually emerge in this process.

    Method: The study is based on a theoretical framework about IT investments and how a purchasing process might look like. It all lead up to a summarizing model made by the authors of this thesis and it shows all the different steps in a purchasing process. The study contains three interviews where two of them were in big companies and one in a smaller company.

    Conclusions: This study shows that depending on the size on a company the decisions are made in one or several levels within the company and that the amounts of levels increase with the size of the company. A smaller company got better possibilities to get information from the end-users and the rest of the staff to make better requirements on the IT solution, which could increase the chance for an IT solution to satisfy their needs. The price of the IT-solution matters in the choice in what to buy and it seems like the price sensitivity increases the smaller size a company is. All company sizes wants long terming relations with a few suppliers. The problem often emerges in the progress to gather the requirements for the IT solution and also in the communication with the suppliers. The problem comes from misunderstandings between the company and the supplier because of different use of language. It also creates problems when there is lack of knowledge amongst the people making the specifications of the requirements for the IT solution.

    TRYCKT MATERIAL TILL ESKILSTUNA KONSTMUSEUM: Informationsbroschyrer om konstmuseet och om samlingen2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Syftet med arbetet har varit att skapa informationsmaterial till Eskilstuna konstmuseum som är anpassat efter målgruppen. Detta önskades eftersom inget liknande material fanns sedan tidigare på konstmuseet. Målet var att besökare och potentiella besökare snabbt skulle kunna få en överblick av vad museet hade att erbjuda. Men också för att ge besökare en möjlighet att kunna få förståelse för vad som visas och hur utställningarna är uppbyggda, utan att behöva gå en guidad tur.

    Detta har gjorts till större delen genom analyser och litteraturstudier, men utprovningar har också varit en stor del av arbetet.

    Resultatet blev två broschyrer som togs fram enligt riktlinjer för informationsdesign, en informationsbroschyr och en broschyr om samlingen.

    Integrating 5G Components into a TSN Discrete Event Simulation Framework2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    TSN has for many years been the staple of reliable communication over traditional switched Ethernet and, has been used to advance the industrial automation sector. However, TSN is not mobile, which is needed to fully enable Industry 4.0. The development of 5G and its promised URLLC combined with TSN would give both a mobile and reliable heterogeneous network. The 3GPP has suggested different designs for a 5G and TSN integration. This thesis investigates the different proposed integration designs. Besides the integration design, one of the most essential steps towards validity of the integration is to evaluate the TSN-5G networks based on simulation. Currently, this simulation environment is missing. The investigation in this thesis shows that the most exhaustive work had been done on the Logical TSN Bridge design for simulators, such as the ones based on OMNeT++. Capabilities of the simulator itself are also investigated, where aspects such as the lack of a 5G medium and clock synchronization are presented. In this thesis, we implement the 5G-TSN component that results in a translator which sets different 5G channel parameters depending on the Ethernet packet's priority and its corresponding value. To verify the functionality of the translator that is developed within the simulator, it is tested in a use case inspired by the vehicle industry, containing both TSN and 5G devices. Results from the use case indicate that the translation is performed correctly.
