    "Ideas are simple. Implementation is Hard.": En Fallstudie om Nyckelfaktorer för Implementering av Planeringssystem inom Hemtjänsten2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Home care are a very common form of care and many prefer this form of care in front of hospitalized care. The home care service is therefore in need of a planning system in order to plan its work as efficiently as possible. Many of these implementations fail.

    Purpose: Many implementations in the home care service fail. The purpose of this paper is therefore to investigate what critical success factors project managers should focus on to achieve a successfull implementation.

    Method: This study has been conducted with a qualitative study as research method. A literature study was carried out by finding previous research in the field, which was then used as a theoretical framework. This was then compared with the empirical evidence acquired through semi-structured interviews with people with experience of implementations in the home care industry.

    Result: The result shows that the CSF’s that appeared in the literature study should also be used in practice. In addition, three new factors were identified

    Conclusion: All of the CSF’s presented in the literature study were reinforced by the interviews conducted with the informants in this study. References to how these should be used have also been developed. For example, the focus on the factor resources should primarily be put on the resource time.This study also concludes that depending on the type of organization it is about, such as small private companies, private medium-sized companies or municipal-owned businesses, focus should be on different CSF’s.

    En policy är bara så bra som personens förmåga att efterleva den: Ett arbete om informationssäkerhetspolicys och hur de följs på arbetsplatsen2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today new applications are used by companies in order to save money and streamline the business process. The advantages are plenty, but considerations have to be made to ensure that the company’s information does not end up in the wrong hands. The aim of this paper is to examine how employees view company policy, in order to figure out whether it is bad policies or the human factor that is the culprit behind information leaks. Earlier studies have shown that more than 50% of information breaches are a result of internal mishappenings. How can companies use policies to ensure that this does not happen? How can they motivate their employees to adhere to such policies? In this paper we conclude, by interviewing employees that regardless of how good a policy is written, it cannot possibly be effective unless the employees are knowledgeable or motivated to adhere to it.

    Government 2.0 och medborgarmedverkan vid utveckling av offentliga digitala tjänster: Möjligheter och utmaningar med medborgarmedverkan i en offentlig organisation2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen har som syfte att identifiera utmaningar som medborgarmedverkan medför inom en offentlig verksamhet vid utveckling av offentliga digitala tjänster. Utifrån dessa utmaningar diskuteras potentiella möjligheter som uppstår när utmaningarna klaras av samt vilken roll IKT och Government 2.0 har i dessa utmaningar och möjligheter. Vidare diskuteras även Participatory Design som tjänstedesignansats utifrån identifierade utmaningar och potentiella möjligheter vid utveckling av offentliga digitala tjänster. Uppsatsens teoretiska referensram redogör främst för forskningsämnena e-Government och Government 2.0 samt tjänstedesignansatser så som Participatory Design och User-Centered Design, samskapande och vikten av att involvera användare. En fallstudie har genomförts i en svensk kommun för att öka förståelsen om medborgarmedverkan vid utveckling av offentliga digitala tjänster. Genom förståelsen av kommunens kontext identifieras nio olika utmaningar:

    Utmaningar:

    1. Arbete för öppenhet och transparens mot medborgare
    2. Skapa mångfald i utvecklingsprojekt
    3. Identifiera fler faktorer, utöver mångfald, för en lyckad medborgarmedverkan
    4. Sprida kunskapen om vilka faktorer som är viktiga för lyckad medborgarmedverkan
    5. Tillfoga sig kunskapen om hur man når ut till medborgare på bästa sätt
    6. Motivera medborgare till att medverka (kommunicera vilket värde medverkan ger för varje enskild medborgare – dvs. kunna svara på frågan ”Varför ska just jag medverka i detta projekt?”)
    7. Bibehålla medverkande medborgare
    8. Öka datakunnigheten hos medborgare och andra aktörer
    9. Använda IKT och Webb 2.0 till dess fulla potential

    Dessa utmaningar ligger sedan till grund för potentiella möjligheter. Möjligheter som innebär öppenhet och transparens där offentliga digitala tjänster kan utvecklas utifrån medborgares och användes behov. Detta genom att använda sig av PD som tjänstedesignansats, IKT och Webb 2.0 – plattformar för samskapande, nätverkande, dialog och kunskapsspridning.

    Experimentell studie av prestandaskillnader mellan native Android och Xamarin för mobilapplikationer2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Throughout the last decade the mobile phone market has grown rapidly and with it, the need for mobile applications has grown as well. When the development process for a mobile application starts, a developer must review various factors that can affect the mobile applications usage or performance, for example the development platform to use which is the focus of this study. The purpose of this study is to determine the difference in performance between native Android and Xamarin cross-compile with the use of an experimental study. The hypothesis of this study is based on previous research which shows that cross-platform and Xamarin cross-compile have worse performance than native Android, the result of this study can contribute can help a developer make the decision on what development platform to choose. The delimitations have been chosen as Android as platform, execution time, CPU-usage and RAM-usage for performance testing. The algorithms that were chosen were an iterative bubble sort, in form of best case, worst case and random case with varying numbers, and a recursive Fibonacci sequence with different starting points. The result of this study is consistent with the hypothesis, Xamarin shows worse performance than native Android.

    Coding in a discrete multitone modulation system1996Student paper other, 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Discrete Multitone (DMT) modulation is a multicarrier technique which makes efficient use of the channel, maximizing the htroughput by sending different numbers of bits on different subchannels. The number of bits on each subchannel depends in the Signal-to-Noise Ratio of the subchannel. The performance of a DMT system can be further increased by using powerful coding techniques. This thesis investigates an implementation of coding for a DMT system. The coding techniques considered are Ree-Solomon coding combined with interleaving, and Trellis Coded Modulation. Wei's 4-dimensional 16-state coder combined with trellis shaping is the suggested trellis code. A single encoder is used which codes across the tones of each DMT-symbol. At a bit error probability of 10 -7 the suggested codes gain 3-6 dB over uncoded transmission. Hardware complexity and algorithmic aspects of coding are covered, as well as simulations to verify it.

    Kommunikation med hjälp av sociala nätverkssidor: En kvalitativ studie om nyblivna pensionärers uppfattning av social närvaro på sociala nätverkssidor2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Behovet av kommunikation har alltid varit en viktig del av människans sociala liv. Den tekniska utvecklingen har möjliggjort nya kommunikationsvägar och sättet att kommunicera har därför förändrats. Syftet med studien är att kartlägga hur yngre pensionärer upplever social närvaro och tillhörighet på sociala nätverkssidor. Målsättningen med studien är att identifiera hur tekniken upplevs möjliggöra eller begränsa graden av social närvaro för yngre pensionärer vid kommunikation över sociala nätverkssidor. 

    Studien tillämpade en kvalitativ metod där semistrukturerade intervjuer användes för att samla in data. Intervjuerna transkriberades enskilt för att i en helhetsanalys tolkas och bilda en samlad bild över det empiriska materialet. Urvalet bestod av yngre pensionärer mellan 66–75 år som använder sociala nätverkssidor. Totalt deltog åtta respondenter. 

    Den insamlade empirin visar att samtliga respondenter är aktiva användare av Facebook men orsakerna till användningen samt vilken typ av aktiviteter som utförs skiljer sig mellan deltagarna. Samtliga respondenter uppger att de använder sociala nätverkssidor för att följa och ta del av familjens- och vännernas liv samt som informationskälla. Respondenternas upplevelse är att sociala nätverkssidor utgör ett komplement till annan kommunikation där den sociala närvaron är lägre på sociala nätverkssidor jämfört med fysiska möten eller telefonsamtal. Empirin visar också att sociala nätverkssidor för yngre pensionärer ger en lägre grad av social närvaro och tillhörighetskänsla än annan kommunikation i textform som SMS eller e-post. Den generella bild som respondenterna uppvisar är att sociala nätverkssidor möjliggör för snabb och flexibel kommunikation men där den lägre graden av social närvaro utgör en begränsning som gör att sociala nätverkssidor inte kan likställas vid fysiska möten. 

    Slutsatsen är att sociala nätverkssidor upplevs ha en lägre grad av social närvaro än annan kommunikation vilket empirin uppvisar med stöd av den teoretiska referensramen. Tekniken som komplement till annan kommunikation erbjuder en upplevelse av tillhörighet och gemenskap och skapar möjligheter för yngre pensionärer att vara sociala. Tekniken som ersättning för alternativ kommunikation skapar istället en begränsning i vad sociala nätverkssidor kan erbjuda för upplevelsen av social närvaro.

    Navigation i komplexa miljöer med hjälp av digitala tjänster och IoT2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Research and implementation of use when it comes to outdoor navigation and GPS systems have come quite far compared to their indoor alternatives. Pedestrian friendly wayfinding solutions for indoor use are still lagging behind, and even more so when it comes to recommendations on implementation of best practice.

    One of our goals during the research process was aimed at finding the most adequate ways of conveying wayfinding solutions to end-users in different situations. In order to perform this task, we used a benchmarking process on a selection of wayfinding alternatives. The goal of this process have been focused on finding out which solutions are available at this moment, what they offer the users in terms of wayfinding support, and where issues might arise based on cognitive user theory, wayfinding best practice and technological limitations concerning mobile devices or different digital platforms.

    During our research we found that there are several different solutions that are available for implementation, but that they all come with their own specific strengths and limitations on both the technological side and for the end-users concerning usability.

    The result of our research has been a collection of qualitative data, and recommendations concerning digital and user limitations connected to our specific case. However, the result of this research should not be limited to our case alone, but rather as a reference point for organizations or developers that wish to implement indoor solutions for users, or for future research within the area of indoor navigation and wayfinding.

    Nyttan med Internet of Things i Offentliga Verksamheter: Att identifiera nyttor, fördelar och utmaningar2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Internet of Things (IoT) är ett hett ämne i dagens samhälle då inte bara saker utan även människor kan kopplas upp mot nätet. För verksamheter ses stora fördelar med att använda sig av tekniken i syfte att ligga i framkant och bli effektivare i sina arbetsprocesser. Denna studie fördjupar sig i vilka identifierade nyttor, fördelar och utmaningar som finns samt om det verkligen finns behov av Internet of Things i verksamheter.

    Studien utgår ifrån en av Region Skånes förvaltningar, Regionservice, som befinner sig på en omfattande digitaliseringsresa av att implementera en ny systemlösning. De intervjuer som gjorts med anställda inom förvaltningen har varit i huvudsakligt syfte att skapa en förståelse för hur den nya systemlösningen kommer att fungera samt deras tankar om att använda Internet of Things. Tillsammans med studiens teori, som fokuserat på nyttor, fördelar och utmaningar med IoT, avslutas studien med en slutsats som är grundad i teorin och den empiriska undersökningen på Regionservice. I slutsatsen presenteras egna åsikter och tankar om hur IoT kommer att bidra med något behov och nytta inom verksamheterna samt vilken påverkan och utmaningar som kan uppstå.

    DNS DDoS Mitigation, via DNS Timer Design Changes2017In: Future Network Systems and Security: Third International Conference, FNSS 2017, Gainesville, FL, USA, August 31 - September 2, 2017, Proceedings / [ed] Robin Doss, Welwyn Piramuthu, Wei Zhou, Springer, 2017, p. 43-55Conference paper (Refereed)
    Abstract [en]

    DDoS attacks have been a problem since 2000. In October 2016, there was a major DDoS attack against the service provider Dyn’s DNS service, which took the service down. This was one of the largest bandwidth DDoS attack ever documented, with attack bandwidth over 650 Gbps. By taking down just Dyn’s DNS service, clients could not obtain the IP addresses, of the organizations hosting their DNS with Dyn, such as Twitter. Our contribution is that we have found a way to mitigate the effect of DDoS attacks against DNS services. We only require some very small algorithm changes, in the DNS protocol. More specifically, we propose to add two additional timers. Even if the end DNS clients don’t support these timers, they will receive our new functionality via the DNS resolvers and recursive servers. In summary, our contributions give much more control to the organizations, as to under which specific conditions the DNS cache entries should be aged or used. This allows the organization to (1) much more quickly expire client DNS caches and (2) to mitigate the DDoS DNS attack effects. Our contributions are also helpful to organizations, even if there are no DDoS DNS attack.

    Riktlinjer för transformationen av en manuellt utförd process till automatisk med hjälp av RPA2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är utveckla riktlinjer som stöd till utvecklare under förarbetet till att automatisera en process med hjälp av RPA. Det framtagna teoretiska ramverket består av designprinciper för tjänster och interaktiva system, samt av verksamhetsutveckling och mer specifikt hur verksamheter behöver utveckla sina processer och rutiner när automatiserade system som RPA implementeras. En fallstudie utfördes hos Länsstyrelsen som önskade automatisera en arbetsprocess med RPA. Datainsamlingen skedde genom intervjuer och observationer i form av informationstillfällen med informanter från Länsstyrelsen. Resultatet från informationstillfällen analyserades på ett tematiskt sätt till två huvudområden som är förstå processen och utbilda anställda. I analysen jämförs de framtagna riktlinjerna med det teoretiska ramverket och riktlinjer för RPA skapade av konsultföretag. I slutsatsen presenteras och motiveras våra riktlinjer, den första riktlinjen fokuserar på att skapa förståelse för processer och om RPA är ett lämpligt alternativ. Om det är fallet är den andra riktlinjen att utbilda anställda vad RPA är och hur implementationen kommer påverka dem.

    Abstract [en]

    This thesis handles the area around time reporting within the consulting field and how it can be facilitated. Time reporting is a must for every employee in the consulting business. In today’s society, a problem exists as the employees sees this to be a demanding extra chore. To manage employees to execute this is a challenge for every business. If this is not done correctly, the business can face huge economic consequences.

    The purpose with this thesis is to facilitate time reporting for consultants. This will be done by developing a Mobile IT-Artifact. The application which will be developed will serve as a support for time reporting and its goal is to minimize the human-computer interaction. The artefact that will be developed uses the phones build in GPS function to achieve this.

    Action Design Research (ADR) is the research method used to complete the development of the artifact and the thesis. This thesis is built around a case in cooperation with the consulting company Knowit. The result of this essay will generate an IT-artifact along with 10 design principles which provides guidelines on how to develop a system of similar character

    Abstract [en]

    This study aims to investigate and create a better understanding of why the different regions of Sweden have chosen their integration platform within the healthcare sector. Due to the decentralisation and political governance there is a complexity within the healthcare sector various integration platforms. The author has looked at the choices that the different regions have made based on strategic, economical, technical, operational and cultural characteristics. The various regions size is also investigated as a factor, making a distinction between higher and lower populated regions.

     

    An integration platform acts as an intermediary, allowing the various systems to communicate with each other without having a point-to-point connection. At present there is no integration platform at the forefront of supporting all the different needs of the different regions, each region finds the solution that is best for itself.

    Utvärdering av hybrida ramverk för mobil applikationsutveckling mot småföretag2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The mobile industry is constantly changing, which has led to a fragmented market that smallbusinesses have difficulties to successfully establish in. Small businesses have had problemswith developing qualitative applications for different mobile devices. The main reason is theresource intensive process to develop native applications for multiple platforms andmaintaining the different codebases. Thus, smaller companies have usually chosen to developweb applications to deliver services to a more widespread target audience. Hybrid frameworkshave established themselves as a potential solution for developing mobile applications withhigher performance and functionality than web applications, while allowing developers to sharecode between platforms. In this study, employees of three smaller companies were interviewedto identify shared requirements held by small businesses to select a framework for applicationdevelopment. Based on the requirements, three hybrid frameworks were compared with thepurpose to identify which one was most suitable for small businesses. The results showed thatsmall businesses are different with varying needs and that there is no specific framework thatsuits all companies. On the other hand, it was found that all three hybrid frameworks comparedin the study were sufficiently developed to be implemented as potential solutions. With thatsaid, hybrid frameworks are not without flaws. Applications developed with hybrid frameworksdoes not yet achieve the same level of performance as native applications and is not platformindependent to the same extent as web applications.

    Abstract [en]

    Aim

    This study looks at how mobile applications have changed the situation for customer

    service employees in Sweden.

    Background

    In just a few years, mobile applications have changed our way of working. New

    electronic tools have been developed and the mobile applications replace manual labour

    as well as paper documents.

    Methodolody

    The study relies on data collection from qualitative interviews conducted with customer

    service employees in Sweden. The empiricism of the interviews has been thematically

    analyzed.

    Results

    The results of the study show that customer service employees work more

    independently now than before and that the accessibility of work-related information

    has improved substantially and become more efficient.

    Conclusion

    Thanks to the accessibility improvement and the enhanced information density, the

    possibility of offering an improved customer experience has increased. The results also

    show the importance of technology to the customer service employees of today.

    Abstract [en]

    There is a increasing number of enrolled students in higher education, which leads toless personal time with the teachers, and therefore supplementary technologies needs to takeplace. This paper investigate how Testbased learning with feedback affects the learningoutcomes in a group of students, by measuring their perceived value. The research also investigateswhat design principles to follow, when working with E-learning and Testbasedlearning with feedback. For this this research an IT-artefact will be created which the studentwill be able to use as a practice tool. With the IT-artefact they will be able to answera number of question, in a subject, and get personalized feedback depending on their score.The quantitative research will then evaluate whether the students perceived thoughts aboutthe IT-artifact and the learning method itself. The result shows eight design principles onhow to design an E-learning tool where student should learn through Test based learningwith feedback. The result also indicates that the perceived feeling of learning is good eventhough a big number of respondents never participated in the survey.

    Creating a ticket vending kiosk system that gathers customer data2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This research aims to create and evaluate a set of design principles regarding the development of ticket selling and data gathering kiosk interfaces within the field of User interaction and experience. This set of design principles will provide the developers with a certain mindset for the specific task at hand.

    The design principles will be defined through the development of a prototype in cooperation with an organization about to host a fair. The prototype will be tested by replacing one of the manned stations at the entrance to the fair. The goal of the test is to compare the efficiency of the system to that of two manned ticket stations located at the entrance.

    The vending machines running this prototype sold 36% of total tickets sold at the entrance. Which is roughly equal to that of the manned stations, proving that a system can be designed to both sell tickets and gather customer data without losing efficiency at the entrance.

    Digital arbetsmiljö ur slutanvändares perspektiv2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den huvudsakliga arbetsmiljön bland Sveriges yrkesverksamma är i dag digital och den vanligaste sjukskrivningsorsaken är besvär som tidigare forskning har visat kan orsakas av brister i den digitala arbetsmiljön. Trots detta är digital arbetsmiljö som forskningsområde relativt nytt och outforskat och ny forskning efterfrågas för att utöka kunskapsbasen.

    Syftet med denna studie är att undersöka hur de anställda på en arbetsplats upplever sin digitala arbetsmiljö ur deras perspektiv som slutanvändare samt hur de upplever att den digitala arbetsmiljön påverkas av införandet av ett ärendehanteringssystem.

    Metoden för studien är en fallstudie med kvalitativ datainsamling i form av individuella semistrukturerade intervjuer av de anställda på en arbetsplats. Intervjuerna låter respondenterna utveckla sina resonemang kring hur de upplever sin digitala arbetsmiljö, hur de tror att de kommer att påverkas av införandet och vilka möjligheter de upplever att de har att påverka sin digitala arbetsmiljö.

    Resultatet analyseras med en deduktiv kategorisering som utgår från en socioteknisk modell för utvärdering av informationssystem. Komplexiteten i den digitala arbetsmiljön tydliggörs och analysen resulterar i att fem övergripande problemområden identifieras.   

    De fem problemråden som identifieras är frågan om ansvar och att ta den digitala arbetsmiljön på allvar, medvetenheten om digitala arbetsmiljöfrågor, avsaknaden av en helhetssyn på digital arbetsmiljö, bristen på information i samband med införandet och känslan av maktlöshet hos de anställda. Problemområden diskuteras utifrån undersökningens kontext och jämförs och förklaras med hjälp av teorier och tidigare forskning om digital arbetsmiljö och socioteknisk teori.

    Slutsatsen som dras av den här studien är att det finns flera brister i arbetet med digital arbetsmiljö på den undersökta arbetsplatsen och att alla problemområden som har identifierats påverkar slutanvändares upplevda maktlöshet.

    Vidare konstateras att den digitala arbetsmiljön består av sociala och tekniska dimensioner som påverkar varandra och studiens resultat tyder på att det krävs en holistisk syn på digital arbetsmiljö för att åtgärda de problemområden som identifierats.

    Drop-out in Living Lab Field Tests: A Contribution to the Definition and the Taxonomy2017In: Research Day Conference proceedings 2017: OpenLivingLab Days, Krakow: ENoLL - European Network of Living Labs , 2017, p. 7-20Conference paper (Refereed)
    Abstract [en]

    Studies on living labs show that the users’ motivation to participate in a field test is higher at the beginning of the project than during the rest of the test, and that users tend to dropout before completing the assigned tasks. However, the literature still lacks theories describing the phenomenon of drop-out within the area of living lab field tests. As the first step of developing a theoretical discourse, the aim of this study is to present an empirically derived taxonomy for the various influential factors on drop-out behavior and to provide a definition for drop-out in living lab field tests. To achieve this goal, we first extracted factors influencing drop-out in the field test by conducting a short literature review on the topic, and then triangulated the factors across 14 semi-structured interviews with experts in living lab field tests. Our findings show that identified reasons for drop-out can be grouped in three categories: innovation-related, research-related and participant-related. Each category in turn, consists of three subcategories with a total of 45 items for drop-out in living lab field tests. In this study, we also explore different types of drop-out and propose a definition for drop-out in living lab field tests.

    Exploring Factors Influencing Participant Drop-Out Behavior in a Living Lab Environment2017In: Scandinavian Conference on Information Systems: 8th Scandinavian Conference on Information Systems, SCIS 2017, Halden, Norway, August 6-8, 2017, Proceedings / [ed] Susanne Stigberg, Joackim Karlsen, Harald Holone, Cathrine Linnes, Cham: Springer, 2017, p. 28-40Conference paper (Refereed)
    Abstract [en]

    The concept of “living lab” is a rather new phenomenon that facilitates user involvement in open innovation activities. The users’ motivations to contribute to the living lab activities at the beginning of the project are usually higher than once the activities are underway. However, the literature still lacks an understanding of what actions are necessary to reduce the likelihood of user drop-out throughout the user engagement process. This study aims to explore key factors that are influential on user drop-out in a living lab setting by engaging users to test an innovation during the pilot phase of the application’s development. The stability of the prototype, ease of use, privacy protection, flexibility of the prototype, effects of reminders, and timing issues are the key influential factors on user drop-out behavior. This paper summarizes the key lessons learned from the case study and points to avenues for future research.

    Equipment-as-experience: A Heidegger-based position of information security2016In: Proceedings of the Thirty Seventh International Conference on Information Systems, 2016Conference paper (Refereed)
    Abstract [en]

    Information security (InfoSec) has ontologically been characterised as an order machine. The order machine connects with other machines through interrupting mechanisms. This way of portraying InfoSec focuses on the correct placement of machine entities to protect information assets. However, what is missing in this view is that for the InfoSec we experience in everyday practice, we are not just observers of the InfoSec phenomena but also active agents of it. To contribute to the quest, we draw on Heidegger's (1962) notion of equipment and propose the concept of equipment-as-experience to understand the ontological position of InfoSec in everyday practice. In this paper we show how equipment-as-experience provides a richer picture of InfoSec as being a fundamental sociotechnical phenomena. We further contend using an example case to illustrate that InfoSec equipment should not be understood merely by its properties (present-at-hand mode), but rather in ready-to-hand mode when put into practice.

    Engagemang och bibehållet engagemang i hälsoapplikationer: Hur engagerande hälsoapplikationer kan hjälpa personer att uppnå mål enskilt och i grupp2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här rapporten har sin ansats i ett företags önskan om att skapa en teknisk lösning för att enklare kunna registrera medarbetares motion i syfte att samla data till en företagstävling. Projektgruppen för detta arbete utgick från teorier som engagement och sustained engagement för att samla kunskap om vad som driver engagement och hur dessa faktorer kan användas för att skapa högre och jämnare användarfrekvens. Tidigare forskning visare att en av de avgörande faktorerna för sustained engagement (över tid bibehållet engagemang) är sociala funktioner i applikationer. De designförslag som projektgruppen studerat i relation till sustained engagement lyfter fram s.k. open-ended design som möjliggör delande av olika typer av innehåll. Projektet resulterade i ett antal personas som beskriver användarna, vidare presenteras ett designförslag och hur detta relaterar till engagement och sustained engagement. Slutligen diskuteras designval och hur väl de möter forskningsfråga och syfte.

    VR-tjänsters utmaningar och möjligheter för samskapande inom hustillverkningsbranschen2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studien syftar till att undersöka VR-tjänsters utmaningar och möjligheter för samskapande av olika varianter av hus inom hustillverkningsbranschen. Genom teoretiska studier och kvalitativa intervjuer har riktlinjer för hur företag kan använda VR-tjänster för samskapande framträtt. De teoretiska områden som främst har behandlats är den tjänstedominanta logiken, innovationsprocessen, samskapande samt VR. Sex intervjudeltagare medverkade i intervjuerna. Dessa var i åldrarna 25–26 år, hälften var män, hälften var kvinnor. Det visade sig att deltagarna hade liten eller till och med ingen erfarenhetav VR sen tidigare.

    Studien visar att företag som ämnar använda sig av VR-tjänster för samskapande bör tänka på att tjänsten måste uppfylla vissa incitament och fördelar som bland annat handlar om att tjänsten måste vara kreativ och inspirerande för att ge så kallade nöjes- och lustfördelar, ge möjlighet till att utföra förändringar av ett virtuellt hus på ett unikt sätt, men även att deltagande i tjänsten i vissa fall även kan kräva någon form av kompensation för attanvändarna ska delta i samskapande. Det kan även krävas en tjänst som är kopplad till VR-tjänsten för att samskapande ska fungera på bästa sätt. Det finns potential för företag attanvända sig av VR-tjänster för att samskapa tillsammans med kunder, men det kan ännu komma att dröja innan användningen av liknande tjänster är utbredd och ett måste för företag att satsa på.

    Usability Testing of Software Products: A case study about usability testing and how to improve the practice2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Usability testing is an important task during development of software products such as web and mobile applications. It is a growing and evolving concept but is often left out during development due to time and costs. Developers are also expected to handle the usability testing but are given minimal training to do so.

    The aim of this thesis is to examine how Tieto uses and perform usability testing when developing their software products. The study is about identifying any issues in the practice and compare it to presented theory and come up with suggestions of change that Tieto can take into consideration.

    The method in this thesis is single case study done with qualitative data collection through observation and semi-structured interviews, to be able to answer the purpose and get a deeper knowledge about what some of the employees at Tieto thinks of usability testing.

    By comparing the result of the study with the presented theory the conclusion can be drawn that the practice of usability testing consists of a few flaws but that the main problem is the organizational culture.

    Testprocessen - struktur, effektivitet och stabilitet2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie behandlar testprocessen och vikten av att ta fram en dokumenterad sådan. I fokus ligger testarnas arbete på en IT-avdelning där man utvecklar interna system ämnade att hjälpa resten av verksamheten i deras dagliga arbete. Eventuella fel i dessa system bör upptäckas så tidigt som möjligt för att undvika onödiga kostnader och detta ansvar ligger till stor del hos testarna. Det är de som testkör systemen och undersöker om de möter kraven och fungerar som det är tänkt. Först när testarna godkänt systemet är det redo att lanseras till användarna. Resultatet av denna studie är en väldefinierad testprocess med tydliga steg att gå igenom innan, under och efter testarbetet. Processen kan testarna luta sig mot för att uppnå struktur, effektivitet och stabilitet i sitt arbete och det de levererar.

    Machine learning på tidsseriedataset: En utvärdering av modeller i Azure Machine Learning Studio2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In line with technology advancements in processing power and storing capabilities through cloud services, higher demands are set on companies’ data sets. Business executives are now expecting analyses of real time data or massive data sets, where traditional Business Intelligence struggle to deliver. The interest of using machine learning to predict trends and patterns which the human eye can’t see is thus higher than ever. Time series data sets are data sets characterised by a time stamp and a value; for example, a sensor data set. The company with which I’ve been in touch collects data from sensors in a control room. In order to predict patterns and in the future using these in combination with other data, the company wants to apply machine learning on their data set. To do this effectively, the right machine learning model needs to be selected. This thesis therefore has the purpose of finding out which machine learning model, or models, from the selected platform – Azure Machine Learning Studio – works best on a time series data set with sensor data. The models are then tested through a machine learning pilot on the company’s data Throughout the thesis, multiple machine learning models from the selected platform are evaluated. For the data set in hand, the conclusion is that a supervised regression model by the type of a Decision Forest Regression model gives the best results and has the best chance to adapt to a data set growing in size. Another conclusion is that more training data is needed to give the model an even better result, especially since it’s taking date and week day into account. Adjustments of the parameters for each model might also affect the result, opening up for further improvements.

    Abstract [en]

    The purpose of this study is to investigate how prototyping of video game levels can be made more accessible by developing a user-friendly game level creation system, evaluating it and producing a number of design principles to be followed when designing such systems. The research question for this study is thus: How can video game level creation be made more accessible? There were several key areas at the center of this study such as Usability, GUI Design, Prototyping, and Game Development. This study utilized an adaption of the Design Science Research Methodology, and evaluation of the resulting artifact was done via user testing and surveys. Survey responses revealed that 95% of the participants successfully completed the main task of the trial, to create a completable video game level within 25 minutes. In addition, all participants answered a 3 (neutral) to 5 (best) on ranked survey questions relating to the usability of the artifact. This study resulted in design principles which were derived from the survey responses via a qualitative decoding process. The conclusion drawn is that computer game level creation can be made more accessible via the development of tools abiding by the design principles proposed by this study.

    Management Accounting and ERP Systems: Factors behind the Choice of Information Systems when Exercising Management Accounting2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Accounting is an old discipline inherent to any business. Accounting is divided into Financial Accounting (FA) and Management Accounting (MA). Financial Accounting focuses on the pure processing of the economic data. Management Accounting focuses on the decision-making aspects of the accounting. Accounting industry has been tremendously transformed in the past two decades due to the implementation of Enterprise Resource Planning (ERP) systems. These systems integrate and unify an organisation’s business functions and processes into one complex computer system. Previous research suggests that the ERP systems’ main functionality primarily addresses the issues of Financial Accounting and much less the issues of Management Accounting. The purpose of this study is to explore the underlying factors behind the application of the Management Accounting Techniques through the ERP systems and to suggest a further development in the field. Five large Swedish companies were examined through the comparative case studies with semi-structured interviews. This study discovered that MATs were mostly implemented through spreadsheets, BI systems and custom-built software, i.e. outside of the ERP systems. The main reasons were inflexibility and standard design of the ERP systems, that did not fully suit the companies. Additionally, the customization of the ERP systems would be too costly when other tools, such as BI systems or spreadsheets, provided better functionality to a better price. The conclusion of this study is that it is impossible to build a universal ERP system that would suit all kind of companies, however, ERP systems can serve as a common base and a transaction engine for the MA. ERP systems can provide a data structure for the analysis parameters crucial to MA, such as profit centre, cost centre, unit, and other dimensionality aspects. Spreadsheets and BI systems win the MA battle by providing the flexibility, user-friendliness and the acceptable price, required by the users. Therefore, ERP systems must provide good integration possibilities with other software. One can further speculate if ERP system providers choose not to deliver flexible and visually appealing products, since they benefit from the income that the customer education and the customization of an ERP system implies.

    Utveckling av en chatbots dialog för implementation i en webbaserad kundtjänst2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Automation of customer service through implementation of chatbots is becoming increasingly common in order to provide customers with a more accessible and efficient service. When implementing chatbots in customer services, human control and the customer experience are partially shifted to a digital system, which puts requirement on the chatbot’s dialogue.

    The purpose of this report is to develop an artifact for a client. The artifact is a web page containing a chatbot. The report aims to develop design principles for development of chatbots and their dialogues in a customer service.

    The research method used in the development of the artifact was Design Science Research Methodology (DSRM). A literature study was conducted, and data was collected through meetings and an interview with the client.

    The report resulted in a demo page containing a chatbot and a page for administrators with an overview of saved chats. Three design principles were also formulated for developing chatbots in customer service, which is the contribution of the report. The conclusions identified were that a chatbot should check that the user got the correct answer, a chatbot should offer human service in case of misunderstanding, a chatbot cannot fully replace human service and a chatbot should have a structured data collection of completed interactions for developing and improvement of the chatbot’s dialogue.

    GDPR och dess påverkan vid systemutveckling: Riktlinjer för en säkrare kravspecificering.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att undersöka vilka nya krav som kan tänkas uppstå i och med det nya dataskyddsdirektivet, och hur uppfyllandet av dessa krav kan underlättas, i form av riktlinjer utformade för att säkerställa en systemutveckling i enlighet med de säkerhets- och integritetskrav som ställs i och med GDPR. De behov och kravområden som identifierats, har sedan kategoriserats och konkretiserats i form av riktlinjer som skall kunna användas då personuppgifter hanteras. För att belysa hur GDPR kan förändra kravbilden har främst “Privacy by Design”, kravspecificering, samt de allmänna juridiska förändringar GDPR kommer att innebära studerats. För att besvara uppsatsens syfte och frågeställningar har en studie baserad på främst semistrukturerade intervjuer utförts. Detta för att identifiera potentiella nya krav som kan tänkas uppstå i och med det nya dataskyddsdirektivet. Med avstamp i teorin, samt intervjuunderlaget har sex stycken kategorier tagits fram. Dessa är samtycke, Privacy by Design, rätten att bli meddelad om intrång, rätten att bli glömd, dataportabilitet samt rätten till åtkomst. Dessa kategorier har sedan legat till grund för de riktlinjer som utgör resultatet av detta arbete.

    AI inom svenska industrier: En marknadsanalys med designförslag2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Swedish companies need to constantly improve their position amongst competitors and artificial intelligence (AI) acts as a tool for achieving that goal. However, AI is a complicated, undefined and hyped concept which makes it difficult forcompanies to increase productivity and reduce cost. AI is a broad concept with many associated subgroups that can be interpreted in many ways. AI in this study is defined based on the market analysis as: A system or machine that can adopt human characteristics or a sorting method tofind and produce a solution to make their business better.

    The purpose of this study is to create an understanding of what AI means for different industries by analysing the Swedish market and to create a solution proposal for how companies canbenefit from AI. This research has used the Design Science Research Methodology (DSRM) as a guideline. This study resulted in a market analysis of AI and a solution proposal for the companies in the different industries to increase their success ratio with their AI planning andimplementation.

    Design Decisions for Indie Development of Educational Video Games: A Case Study2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Educational video games – especially for the PC market – do not seem to perform as well commercially as games from other genres. We argue that there is room for independent – ’indie’ – developers to break into the marketplace, by identifying certain niches and innovating on the genre. This would generate commercial value for such actors and knowledge value for the players.

    Design decisions of high importance made during development of an educational video game demo at the small Swedish company Toleap Consulting AB were analysed in the pursuit of contributing to effective indie development of such games. Three main problems that arose during development were identified, and three design decisions where implemented to combat these respective problems; (1) Interpreted educational game pattern utilising XML, (2) Function-based game views and (3) Community created assets, open source, and no costly dependencies. In our case, the formulated design decisions effectively solved our problems, and we argue that they generalise.

    If a developer creating a similar game (educational video game) in a similar situation (independent development with limited resources) encounters one or more of these problems, the suggested design decisions may help the developer solve the problems, in turn making more educational video games available on the market, generating the aforementioned commercial and knowledge values.

    Ansvar och dilemman vid applikationsutveckling för mobila enheter2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Digitaliseringen av samhället har inneburit stora förändringar för både verksamheter och privatpersoner, såväl möjligheter som utmaningar. Från det att iPhone introducerats har utvecklingen av både smartphones och nya digitala tjänster fått en explosiv tillväxt. I takt med ökningen av dessa nya digitala tjänster och applikationer medför detta både positiva förändringar likväl oavsiktliga konsekvenser. Det finns svårigheter med dessa oavsiktliga konsekvenser vid applikationsutveckling eftersom det är svåra att förutse samt att det är svårt att förutse hur människor kommer agera när de använder den färdiga applikationen. Denna studie syftar till att öka förståelse för vikten av utvecklares ansvar samt utmaningar vid applikationsanvändning, vilket bör uppmärksammas vid applikationsutveckling och nya digitala tjänster.

     

    För att uppnå detta tillämpades designprocessen som har strukturerat studien för att ta fram vårt designförslag som presenteras i form av en prototyp för en parkeringsapplikation samt rekommendationer för utvecklare. Designförslaget och rekommendationerna bygger på den data som har samlats in genom kvalitativa djupintervjuer med utvecklare samt undersökning för hur dagsläget ser ut vad gäller ansvar och dilemman vid utveckling.

     

    Resultatet visar på hur viktigt det är att kravspecifikationer från kunden är väl utförda för att slutprodukten ska uppnå bästa resultat. Däremot finns det inte alltid tillräcklig tydliga riktlinjer att följa inom dessa utvecklingsverksamheter för att fatta beslut. Skulle ett projekt ge upphov till ett dåligt utfall är det upp till den enskilda individen att belysa situationen. En situation där den enskilda individens ansvarsförmåga spelar in. Resultatet av intervjuerna samt rekommendationerna har därmed kunnat generera ett designförslag för hur ansvar kan tillämpas vid applikationsutveckling. Slutsatsen är att vid utveckling bör balans mellan ansvar och användarupplevelse eftersträvas. Utvecklas säkerhetsåtgärder som ska implementeras i en applikation ska de framkalla en positiv attityd och påvisa användare snarare än bestämma över deras interaktion.

    Small and medium sized firms’ businesses in rural regions typically address a home market and the delivery of niched products. This makes them exposed to business downturns, innovation is thus one way to survive and prosper. Small-scale product development is typically very hands-on, a sort of trial and error process. This experimental way is in favour for the implementation of innovation processes, but one challenge is the limited resources that firms can, or are willing to, spend on innovative work. A challenge is that procedures for organisational learning are lacking in the straightforward approach. The article describes the background and rationale for supporting small-scale manufacturing by introducing a support toolbox for early product development work. The support toolbox’s rationale is built upon learning cycles and communicative prototyping which may enhance innovation process capabilities.

    Information Security Awareness amongst students: A study about information security awareness at universities2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the era of information, it has become vital for companies to make sure that their information is properly protected. They are therefore, willing to spend large amounts of resources on protecting their information. This can usually be done in a large variety of ways. The root of information security is first and foremost, having policies that regulate how information security is upheld. And secondly, by teaching employees proper practice of information security. These are however procedures that are not all that common in a university environment, and even more so in relation to students.

     

    In order to explore this phenomenon further, an exploratory study have been carried out to find more information on the subject. This has been done in several ways in order to grasp as much information as possible. Firstly, by doing a literary study to find out what is already known within the field of information security in regard to students. Secondly, by doing a quantitative study that evaluates the student’s information security awareness. And lastly, by conducting an interview with a member of staff at a university to find out their attitude towards the phenomenon. 

     

    The thesis concludes by suggesting how universities might want to handle information security in relationship to students.

    CoFramer: Ett diskussionsformat för djupa diskussioner på publika forum med låg Information Overload inspirerat av Philosophy for Children2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The focus of this essay is to develop a design concept for online public discussions with deep discussions and low information overload. The method used is Concept Driven Interaction Design (CDID) which involves constructing a design concept by applying a variety of theories in tangible interaction design. A design concept has three basic parts: a name, high-level goals and outlines generic principles. CDID includes seven steps which is used in this work:

    1.      Concept Generation – Formatted into a table that compare forum discussion (with several hypothesis) compared to discussions with the method Philosophy for Children (P4C) and other theories.

    2.      Concept Exploration – Eight distinct design aspects are identified from the comparison table.

    3.      Internal Concept Critique – The design aspects are compared to three similar discussion formats.

    4.      Design of Artifacts – Design concept version 1 is created.

    5.      External Design Critique – Interviews are conducted to explore their general experience of online discussions, investigate the hypothesis from the comparison table and to seek direct feedback on the first draft of the design concept.

    6.      Concept Revisited – Changes are made to the design concept based on the interview material and the direct feedback.

    7.      Concept Contextualization – The design concept is related to the original literature.

    The result of the study is a design concept named CoFramer. CoFramer’s generic principles are summarized and contrasted against factors identified from the interview material in this table:

    Tabell 2: CoFramer’s generic principles and interviews about online discussions.

    CoFramer’s generic principles | From interview material on forum discussion

    Organized start and ending | Discussions without clear ending

    Limited number of participants | Large number of participants

    Minimum number of participants | Large number of inactive spectators

    Explicit participants | Low information about participants

    Common conditions | Vagueness in participants conditions

    Limited information density per post | Long posts and/or fast posts

    The red thread and parallel threads | Often parallel threads

    Active facilitator | Unresolved misunderstandings

    The study indicates that CoFramer would create more structured discussions with a lower amount of information overload and less grounding cost compared what normally arise in public online discussions.

    Dynamic Interplay in the Information Security Risk Management Process2019In: International Journal of Risk Assessment and Management, ISSN 1466-8297, E-ISSN 1741-5241, Vol. 22, no 2, p. 212-230Article in journal (Refereed)
    Abstract [en]

    In this paper, the formal processes so often assumed in information security risk management and its activities are investigated. For instance, information classification, risk analysis, and security controls are often presented in a predominantly instrumental progression. This approach, however, has received scholarly criticism, as it omits social and organizational aspects, creating a gap between formal and actual processes. This study argues that there is an incomplete understanding of how the activities within these processes actually interplay in practice. For this study, senior information security managers from four major Swedish government agencies were interviewed. As a result, twelve characteristics are presented that reflect an interplay between activities and that have implications for research, as well as for developers of standards and guidelines. The study’s conclusions suggest that the information security risk management process should be seen more as an emerging process, where each activity interplays dynamically in response to new requirements and organizational and social challenges.

    Virtuell ljussättning inom Augmented Reality: Semi-automatisk ljushantering för ökad upplevd realism2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to examine how an improved level of experienced realism could be achieved in Augmented Reality (AR) applications, by allowing increased user interaction with a chosen set of virtual lighting parameters. The theoretical foundation of this thesis is both concerned with surveys and literature reviews of AR in general but also virtual lighting and lighting parameters to a significant extent. In contrast to the majority of previous research, where estimating and managing virtual lighting is done automatically, this study suggests that a semi-automatic approach might be better suited in delivering improved levels of experienced realism. Through the course of this thesis it is also intended to evaluate which of the chosen lighting parameters that has had the greatest impact in achieving improved experienced realism. Action Design Research (ADR) is applied as the core research methodology and in collaboration with the company Neava, an addon for an existing AR application is developed. This addon enables manual adjustments of virtual light direction, intensity and color temperature. The addon is tested by users of the existing application under observation, afterwards the testers answer a brief survey concerning the test, where a comparison between existing application and addon is made. Data gathered from both the observations and the surveys are then subjects of an analysis, where different phenomena and findings regarding improved experienced realism is the focus. The study finds that roughly 90% of the testers did indeed experience an improved level of realism, using the semi-automatic addon. Furthermore the study finds that the virtual lighting parameter most effective in achieving this is light direction, followed by light intensity and least effective in the effort is color temperature. The conclusions made of this study are finally presented in the form of a list of design principles.

    Leveraging an Active Directory for the Generation of Honeywords2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Honeywords, fake passwords that when used by an adversary are set to trigger an alarm, is one way of detecting security breaches. For them to be effective, however, they must resemble real passwords as closely as possible and thus, the construction of the honeywords is crucial.

    In this thesis, a new model for generating honeywords, PII-Syntax, is presented that was built in part on a previous model but reworked and adapted to meet new requirements. The purpose of the study was to investigate whether an Active Directory, (AD) could be used as a resource in the construction of honeywords. The assumption was that the AD contains information about real system users that could be leveraged to create high-quality honeywords because of the very fact that they are based on actual users. It is a well-known fact that many users have a natural inclination towards incorporating personal information when choosing their passwords, information that can be leveraged by an adversary making the passwords easier to retrieve. The proposed model capitalizes on this fact and bases the honeyword generation process on users’ personally identifiable information, PII. The motivation for this is to enhance the quality of the honeywords, i.e. making them more plausible from the perspective of the adversary.

    The resulting model performed equally well or better than all existing honeyword generation algorithms to which it was compared with regard to flatness, DoS resistivity, multiple system vulnerability and storage cost. The most important contribution, however, is the inclusion of users’ personal information in the generation of the honeywords that ultimately help strengthen the security of password-based authentication systems.

    Contributions from this thesis include a novel manner in which to approach a well-known problem, both in a theoretical as well as a practical sense: PII-Syntax is a new honeyword generation algorithm that apart from performing equally well or better than previous algorithms brings an added value of believability to the generated honeywords because of the inclusion of users’ personal information found in an AD.

    Emerging Security Risks within Hybrid Datacenter Infrastructure : A Risk Assesment2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Datacenters are critical infrastructures in today’s information society, they have undergone significant transformation from their inception days within their underlying technological infrastructure. They are at the core of the cloud computing revolution which is changing business models on how organizations deal with their spending on IT infrastructure.Virtualization has been the disruptive force driving this transformation within the datacenter space and has enhancing efficiencies in terms of server load consolidation, resource provisioning,flexibility, and scalability, lower spend on buying equipment and improved power utilization efficiency. The transition phase has led to modern datacenters incorporating both the legacy traditional datacenter infrastructure with the latest ones that are based on fully virtualized solutions. Though this mix of infrastructures has improved resource utilization and consolidation,the flexibility and scalability aspect that they bring about ushers in new set of emerging security challenges to the modern datacenter.The contents of this research work present a comprehensive Risk Assessment to a set of recentlyidentified security risks extracted from the NIST vulnerability database, these risks are related tothe flexibility and scalability aspect of modern datacenters. The findings of this study show thatvirtualization techniques introduce a set of new security flaws at the Hypervisor level, SDN Controllers and Virtual network layers thus further exacerbating challenges in ServiceAvailability, Confidentiality and Data Integrity in modern datacenters. An EBIOS approach to risk assessment was utilized as the guiding methodology. Security recommendations according to security best practices were then proposed as remedial mitigation measures. Ascertaining risk is crucial component for decision makers and the findings of this thesis research work contribute to that by providing better insight to the emerging security risks in a hybrid infrastructure context. The noted findings have implications to security design considerations for prospective datacenter providers who intend to deploy modern hybrid datacenter infrastructure or those in the process of transition.

    Ett land i kris: Digital kriskommunikation vid luftangrepp2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det finns en stor kunskapsbrist hos Sveriges civilbefolkning gällande utomhussirener och vilka tillhörande skyddsåtgärder som finns med dessa. I Sverige finns det skyddsrum för en stor majoritet av invånarna och det ska byggas ännu fler, men det är endast en minoritet som vet vart dessa finns, eller när de ska tas i bruk. Trots att det har talats mer om säkerhetshot runtom i Europa den senaste tiden så är denna kunskapsbrist fortfarande stor. Det finns en svårighet med att göra människor intresserade av förebyggande åtgärder för kriser vilket innebär att det behövs en annan åtgärd för att nå fram till människorna. 

    Syftet med uppsatsen är att identifiera designprinciper för en digital kriskommunikationslösning som hjälper civilbefolkningen att förstå ett befintligt hot och dess tillhörande skyddsåtgärd samt hur denna åtgärd kan vidtas. Dessa designprinciper ska sedan utgöra grund för design av en digital lösning som är tillgänglig, enkel och tydlig att använda.  

    För att åstadkomma detta så använder vi oss utav Design Science Research där vi tar fram en artefakt i form utav en design mockup som är baserad på de existerande designprinciperna som finns inom kriskommunikation med hänsyn till hur människor reagerar. Genom att utvärdera denna artefakt så får vi fram nya designprinciper som behövs för att kunna föra en lyckad kriskommunikation till befolkningen. 

    Tillsammans med principerna vi baserade vår artefakt på, med de designprinciper vi har lyckats ta fram efter att respondenter har testat och utvärderat artefakten så blev detta resultatet för hur kriskommunikationen kan föras digitalt på ett effektivt och tillitsfullt sätt. Denna samling av designprinciper är även något som kan fortsätta att byggas vidare för att få en djupare förståelse eller gå in djupare på detaljer kring designen och informationen som bör förmedlas.
