    Informationsförvaltning inom en stor organisation: En fallstudie på Trafikverket2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to investigate how large organizations can work with information management by examining an organization's existing information management, and investigate possible future proposals to information management. Furthermore, the study aims to investigate how an organization can establish a clear direction, collaboration, management and responsibilities and roles regarding information management.

    This study is qualitative, where data collection occurs through document studies and interviews. The study is conducted by an abductive research approach and the study is a normative case study as the study's goal is to provide guidance and propose measures to the case that the collaboration partner has asked me to study. The case in this study is a typical instance, because the result will be representative of more than the study's collaboration partner, such as other large organizations with similar cases concerning information management.

    To collect theory to the study I conducted literature reviews on topics that are relevant to the purpose of the study: Information management, Business Intelligence, Data Warehouse and its architecture, as well as Business Intelligence Competency Center.

    This study contributes with practical knowledge, because the study provides answers to practical problems the collaboration partner has expressed within the non-operated information management, and this study contributes with suggestions for future information management. The suggestions involve a centralized Data Warehouse and the development of a function that handles information management, and disseminate the governance of information management throughout the organization.

    Cloud computing - Moving to the cloud2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cloud computing involves the use of computer resources that are available through a network, usually the Internet and it is an area that has grown rapidly in recent years. More and more companies move entire or part of their operations to the cloud.Sogeti in Borlänge needs to move their development environments to a cloud service as operating and maintaining of these are costly and time-consuming. As a Microsoft Partner, Sogeti wants to use Microsoft´s services for cloud computing, Windows Azure, for this purpose. Migration to the cloud is a new area for Sogeti and they do not have any descriptions of how this process works.Our mission was to develop an approach for the migration of an IT-solution to the cloud. Part of the mission included the identifying of cloud computing, its components, benefits and drawbacks, which lead to us acquiring basic knowledge of the subject.To develop an approach to migration, we performed several migrations of virtual machines to Windows Azure, and based on these migrations, literature studies and interviews we drew conclusions that resulted in an overall approach for migration to the cloud.The results have shown that it is difficult to make a general but detailed description of an approach to migration, as the scenario looks different depending on what to migrate and what type of cloud service is used. However, based on our experiences from our migrations, along with literature, documents and interviews we have lifted our knowledge to a general level. From this knowledge, we have compiled a general approach with greater focus on the preparatory activities that an organization should implement before migration.Our studies also resulted in an in-depth description of cloud computing. In our studies we did not find previous works in which the critical success factors have been described in the context of cloud computing. In our empirical work, we identified three critical success factors for cloud computing and in doing so covered up some of the knowledge gap in between.

    Utveckling av en mobiltelefontjänst för att spela in TV-program på din dator från distans2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Denna rapport är resultatet av kursen Examensarbete i Informatik på Högskolan Dalarna. Examensarbetet är uppdelat i två delar. Ena delen har som syfte att ge en förstagångsanvändare en introduktion i Mobile.NET. Här beskrivs även vissa skillnader mot traditionell ASP. Andra delen, som uppfyller målet har varit att utveckla en tjänst som gör det möjligt att spela in tv-program på en dator från olika mobila enheter samt pc. Det arbete som föranlett rapporten har bestått av en egenhändigt framtagen metod som hämtat inspiration från Direct-modellen samt Polyas generella metod. Slutsatserna som framkommit är att det idag inte finns tillräckligt bra wap-tjänster som lockar allmänheten att wappa. Mobiltelefonen kommer till sin fulla rätt som en förlängd fjärr-kontroll, som kan integrera människan med hemmet på långa avstånd. För att utvecklingen av wap-tjänster ska ta fart krävs högre prestanda och nya idéer om tjänster. En tanke är att fler tjänster och nya idéer kommer ta fart nu när Microsoft släppt sitt utvecklingsverktyg Mobile Internet Toolkit. Nu behöver utvecklaren inte göra en tillämpning för varje mobilenhet. Kanske kommer denna rapport väcka en ny tanke om vad wap-tjänster kan göra.

    GIS-portal - Utredning och design av GIS-portal och ingående tjänst åt Vägverket2004Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [sv]

    Denna rapport presenterar ett examensarbete på D-nivå där uppdragsgivaren har varit WM-data Consulting och kunden Vägverket Produktion. Vägverket har ett antal olika applikationer för geografisk information som ligger utspridda på företagets hemsida . För att samla alla applikationer på ett och samma ställe fick vi i uppdrag att göra en grundläggande utredning av en GIS-portal. Denna portal ska fungera som en enhetlig ingång där kartdata samkörs och visualiseras. Ytterligare en del i uppdraget var att utreda vad som borde förändras och förbättras i den redan existerande tjänsten Beläggning på vägarna. Denna tjänst kommer att fungera som en testapplikation för GIS-portalen. Målen med examensarbetet var att utreda vilka krav som finns på en GIS-portal och applikationen Beläggning på vägarna samt att beskriva de önskemål som finns på dessa. Ett designförslag och en funktionsbeskrivning arbetades fram för både tjänsten Beläggning på vägarna och för GIS-portalen. Utredningen kommer att ligga till grund för utveckling av en GIS-portal samt fortsatt utveckling och förbättringar av tjänsten Beläggning på vägarna. För att komma fram till ett resultat har vi använt oss av ett antal teorier om IT-tjänster, systemarkitektur och användbarhet. Förutom dessa teorier har även de intervjuer som utförts spelat en stor roll för vårt arbete. Vi har lagt en bra grund för Vägverket att fortsätta arbetet med utveckling av en GIS-portal och tjänsten Beläggning på vägarna.

    Utvärdering av pm3 som förvaltningsstyrningsmodell: En fallstudie på Trafikverket2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The maintenance management model (Pm3) is a management model whose goal is to contribute to the collaboration between the business and IT. An implementation of pm3 involves applying the model, it must be implemented with the business existing governance and work methods. The purpose of the study is to investigate to be able to describe and evaluate the use of pm3 as a management model in a state agency. The study is carried out at the Swedish Transport Administration and their implementation of pm3. The aim of the study is to answer the research question which is “how pm3 can be implemented and applied to be more effective?”. The strategy that has been applied is a case study. The data collection methods are interviews and document studies where qualitative data has been generated. The results of the study show a number of different positive effects that implementation of pm3 can have on a business such as better collaboration, cost effectiveness and clearer overall picture. Some challenges and problems are also identified and a lot of them can be linked to the lack of implementation of the model at the Swedish Transport Administration. To maximize the implementation of pm3, this study has come to the conclusion that it is important with internal education in the management model. This to increase the chance of a successful implementation. Taking external help from the pm3 license is also a way to improve the implementation, as it offers external help and support from external experts. After implementation, it is also important to have an active management of the model, so that the business receives support to work properly over time. Recommendations for future studies is how to follow up on your implementation and establish your governance with pm3 over time.

    Mobile technologies for development – a comparative study on challenges2008In: Proceedings of Sig GlobDev Workshop Paris 2008, Paris: AIS SIG GLobal Development , 2008Conference paper (Refereed)
    Abstract [en]

    This paper compares and analyzes three cases where mobile technology is developed and used for everyday learning in developing countries. Preliminary results from field studies and tests are presented and analyzed in terms of the technical, professional, social, cultural and organizational challenges involved in development. In Bangladesh Virtual Classroom SMS is used together with TV to make education interactive. The eduPhone project develops a system and a method for delivering everyday “situated education”, such as emergency medical advice, to people lacking access to such services. The Agricultural Market Information System project disseminates information to improve local agricultural markets and, in particular, supporting small farmers, by mobile phones. The paper reports the cases and findings from investigations and tests, including field studies, laboratory and field tests, and experiences from implementation. We find that technical challenges are not great and in most cases concern innovativeness of application rather than access, use and usability; e-readiness among people is higher than often reported. The main problems lie in organizational challenges – developing a sustainable business model and reorganizing processes consequently – and social and cultural challenges such as local power structures and professional traditions.

    Inclusion in the e-service society: investigating administrative literacy requirements for using e-services2007In: Electronic government: 6th International Conference, EGOV 2007, Regensburg, Germany, September 3-7, 2007. Proceedings / [ed] Maria A.Wimmer, Jochen Scholl, Åke Grönlund, Berlin: Springer , 2007, p. 216-227Conference paper (Refereed)
    Abstract [en]

    This paper investigates potential changes in requirements for "administrative literacy" - knowledge and skills required from citizens - when manual services are replaced by electronic ones. Do requirements increase, decrease or change qualitatively? We compare manual and electronic versions of ten commonly used services. The needs for knowledge and skills, content and procedures were considerably less for the e-services in eight out of ten cases; however, in complicated services there may rather be a change of skills, e.g. replacing verbal skills with skill in searching for information online. E-services relieve the user of some requirements; hence one obstacle for inclusion is reduced. However, we also found problems with the e-services implying that design of e-services should be informed by the kind of measure we have used as it is of great importance for inclusion in the e-society. © Springer-Verlag Berlin Heidelberg 2007.

    Datakvalitet. Ett måste för en kostnadsmedveten organisation2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Uppsatsen visar resultatet av en kartläggning och analys av datakvaliteten i databasen Vägdatabanken på Vägverket. Vi har studerat datakvaliteten som den visar sig hos slutanvändarna, i detta fall de som upphandlar drift och underhåll av statliga vägar. Målet var att se hur väl Vägverkets krav på data stämmer överens med användarnas behov. För att nå målet skapades en modell med sju faser. Centralt var kartläggningen av verksamheten med hjälp av intervjuer, som blev grunden för vidare analyser. En egen modell var nödvändig eftersom arbetssättet, att utgå från användarna, inte är det vedertagna sättet att undersöka datakvalitet. Resultatet visar en rad kostnader som kan härröras till bristande datakvalitet varav många är dolda. Trovärdigheten är viktig i samband med datakvalitet. Användarna litar inte på data vilket skapar direkta kostnader, merarbete med mera. Det beror i sin tur på att det brister i insamlingen av data. Ett problem är att en rad olika arbetssätt och förhållningssätt till data i Vägdatabanken förekommer. Därför rekommenderas att Vägverket beslutar vilket arbetssätt som är ekonomiskt och funktionellt bäst. Syftet var att beskriva begreppet datakvalitet. Resultatet av praktiskt arbete och teoretiska studier ger definitionen "Datakvalitet är datas förmåga att vara förståelig och trovärdig samt tillräckligt väl uppfylla användarens behov".

    Tillit och misstro till molntjänster: Identifiering av vilka kriterier som skapar tillit till molntjänster2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cloud Computing means the possibility to use computer power and IT-resources through internet. The use of cloud computing have rapidly increased the last few years. The opportunities it brings has led to challenges in trust to Cloud services by enabling new form of relations between customer and suppliers. Nowadays, trust in Cloud services is a problem for customers such as microenterprises, small and medium business.

    Our thesis work seeks to describe microenterprises, small and medium business’s trust and distrust to Cloud services and identify which criteria contributes to this. The result shows that is hard to clearly define trust and distrust in business, as their situations and activities differ from one another. Thanks to out literature review combined with the interviews we’ve conducted, we have created a good understanding of what contributes to trust and distrust in Cloud services. Based on our thesis work, we’ve compiled a conceptual model that describes trust and distrust in Cloud services.

    En analys av testprocesser med TMap som testmetod2009Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems. TMap haven't been used as much as desired in the office in Borlänge. Because Microsoft is releasing a new version of their platform Visual Studio Team System (VSTS 2010) some colleges at Sogeti in the Netherlands are about to develop a template that can support the use of TMap in VSTS 2010. When we write this the template is still in development. The goal for Sogeti was to find out the differences between the test functionality in VSTS 2008 and 2010. By using the purpose with this essay, which was to analyze the test process in VSTS 2008 with TMap against the test process in VSTS 2010 together with the template we got much help to achieve the goal. The analysis was done with four different aspects: The TPI and TMMi models, problem and strength analyses and a few question formulations. The TPI and TMMi models where used to analyses and evaluate the test process. The analysis showed that there were differences between the both test processes. VSTS 2010 together with the template gave a better support to use TMap and perform test. In VSTS 2010 the test tool Camano is connected to TFS and the tool is also to make the execution and logging of tests easier. This leads to a test process that is easier to handle and has a better support for TMap.

    Clean Code vs Dirty Code: Ett fältexperiment för att förklara hur Clean Code påverkar kodförståelse2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Summary: Big and complex codebases with inadequate understandability, is a problem which is becoming more common among companies today. Inadequate understandability leads to bigger time requirements when maintaining code, which means increased costs for a company. Clean Code is according to some people the solution to this problem. Clean Code is a collection of guidelines and principles for how to write code which is easy to understand and maintain. A gap of knowledge was identified, as there is little empirical data that investigates how Clean Code affects understandability. This lead to the following the question: How is the understandability affected when modifying source code which has been refactored according to the Clean Code principles regarding names and functions? In order to investigate how Clean Code affects understandability, a field experiment was conducted in collaboration with the company CGM Lab Scandinavia in Borlänge. In the field experiment data in the form of time and experienced understandability was collected and analyzed.The result of this study doesn’t show any clear signs of immediate improvements or worsening when it comes to understandability. This is because even though all participants prefer Clean Code, this doesn’t show in the measured time of the experiment. This leads me to the conclusion that the effects of Clean Code aren’t immediate, since developers hasn’t been able to adapt to Clean Code, and therefore are not able to utilize its benefits properly. This study gives a hint of the potential Clean Code has to improve understandability

    Mognadsgrad och förbättringsförslag av acceptanstester inom Trafikverkets verksamheter baserat på TMM2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Currently at Trafikverket acceptance testing is done without knowing the test process strengths and weaknesses. This case-study uses Test Maturity Model (TMM) to identify a maturity level for the test process in acceptance testing. The maturity level show how the current process operate and present the test process current weaknesses and strengths. Acceptance testing within ProjectWise reached a maturity level of three. The improvement proposals were to perform continuous workshops for education purposes, so the knowledge within the testing area does not stagnate, and to quantify quality factors for measurement of test.

    Though no model is perfect this study will attempt to do a method analysis based on MA/SIMM, to show the strengths and weaknesses.

    Some of the weaknesses are the lack of experience within the use of the criterias of the TMM model. The criterias are fulfilled by interviews and questionnaires and can be misinterpreted. The answers in the questionnaires are predefined and may confuse the respondent. These weaknesses may eventually cause the wrong maturity level being set.

    There are well documented guidelines when the TMM process has begun so even a inexperienced student may perform a TMM evaluation. The greatest strength in TMM is that it has a scientific background, combined with 40 years of experience within the testing industry, makes it a well-founded model with trustworthy improvement proposals.

    Abstract [en]

    When booking a trip along the railway through several train operators it is not uncommon

    that information about possible disruptions along the railway (that can change or cancel

    the booked trip) are not relayed to the passengers. Today, research on rail traffic in

    Sweden is limited. It is unclear how satisfied customers are with the quality of the

    information they receive during their trip (if they get it at all), including with respect to

    disruptions. Our partners have identified what they believe is a need among train

    operators, which is a service for disruption information to travelers. In addition to

    confirming that there is a need for such a service, we have an interest to investigate how

    such a service might look like and what the users want. Our research has shown that

    passengers are not satisfied with either the amount of information about disturbances or

    how often they get it. Along with KnowitBorlänge, we have come up with a proposed

    solution that uses already existing technologies to create a portal for an efficient way to

    get the interference information to travelers.

    How does data quality in a network affect heuristic solutions?2014Report (Other academic)
    Abstract [en]

    To have good data quality with high complexity is often seen to be important. Intuition says that the higher accuracy and complexity the data have the better the analytic solutions becomes if it is possible to handle the increasing computing time. However, for most of the practical computational problems, high complexity data means that computational times become too long or that heuristics used to solve the problem have difficulties to reach good solutions. This is even further stressed when the size of the combinatorial problem increases. Consequently, we often need a simplified data to deal with complex combinatorial problems. In this study we stress the question of how the complexity and accuracy in a network affect the quality of the heuristic solutions for different sizes of the combinatorial problem. We evaluate this question by applying the commonly used

    p-median model, which is used to find optimal locations in a network of p supply points that serve n demand points. To evaluate this, we vary both the accuracy (the number of nodes) of the network and the size of the combinatorial problem (p).

    The investigation is conducted by the means of a case study in a region in Sweden with an asymmetrically distributed population (15,000 weighted demand points), Dalecarlia. To locate 5 to 50 supply points we use the national transport administrations official road network (NVDB). The road network consists of 1.5 million nodes. To find the optimal location we start with 500 candidate nodes in the network and increase the number of candidate nodes in steps up to 67,000 (which is aggregated from the 1.5 million nodes). To find the optimal solution we use a simulated annealing algorithm with adaptive tuning of the temperature. The results show that there is a limited

    improvement in the optimal solutions when the accuracy in the road network increase and the combinatorial problem (low

    p) is simple. When the combinatorial problem is complex (large p) the improvements of increasing the accuracy in the road network are much larger. The results also show that choice of the best accuracy of the network depends on the complexity of the combinatorial (varying p) problem.

    To what extent do neighbouring populations affect local population growth over time?2016In: Population, Space and Place, ISSN 1544-8444, E-ISSN 1544-8452, Vol. 22, no 1, p. 68-83Article in journal (Refereed)
    Abstract [en]

    This study covers a period when society changed from a pre-industrial agricultural society to a post-industrial service-producing society. Parallel with this social transformation, major population changes took place. In this study, we analyse to what extent local population change is affected by neighbouring populations. To do this, we focused on the last 190 years of local population change that redistributed population in Sweden. We used literature to identify several different processes in the population redistribution. The different processes implied different spatial dependencies between local population change and the surrounding populations. The analysis is based on an unchanged historical parish division, and we used an index of local spatial correlation to describe different types of spatial dependencies that influenced the redistribution of the population. To control inherent time dependencies, we introduced a non-separable spatial-temporal correlation model into the analysis of population redistribution. Hereby, several different spatial dependencies could be simultaneously observed over time. The main conclusions are that while local population changes have been highly dependent on neighbouring populations in the 19th century, this spatial dependence became insignificant already when two parishes are separated by 5 km in the late 20th century. It is argued that the only process that significantly redistributed the population at the end of the 20th century is the immigration to Sweden.

    Det är första gången som Triona AB gör om en webbapplikation till en Androidapplikation och således saknas det information och dokumentation för hur det skall göras, det vill säga en plattformsmigrering. Vi gjorde i detta projekt om en webbaserad cykelreseplanerare till en androidapplikation och med utgångspunkt från de erfarenheter vi fick utifrån den tog vi fram en arbetsgång för plattformsbyte från en webbapplikation till en mobilapplikation. Den teoretiska grunden för projektet lades genom litteraturstudier samt intervjuer. Dessa la grunden för det preliminära förslaget för arbetsgång som skulle komma att testas hos Triona AB. Att genomföra en plattformsmigrering hos Triona AB vilket innebar att vi gjorde om deras webbapplikation till en androidapplikation gav oss vår empiriska grund. Efter att ha testat det preliminära förslaget på arbetsgång hos Triona kunde vi modifiera samt verifiera den. Vi skulle i efterhand försökt utvidga vår intervju-del med fler personer men detta var tyvärr inte möjligt vid genomförandet på grund utav av bristande intresse att delta från olika företags sida.

    Utveckling av Hedlunds Hus AB webbplats2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    För att visa på nyttan av vad ett användartest kan erbjuda i samband med utveckling av en webbplats har vi i denna rapport tagit med alla stegen fram till och med utveckling i Vattenfallsmetoden, som är den metod som vi använt oss av. De föregående stegen i metoden är förstudie, analys och design. Förstudien valde vi att genomföra som ett användartest för att få fram vad användarna verkligen efterfrågade. Vi analyserade sedan resultatet av användartestet och gjorde en sammanfattning, men i den tog vi även hänsyn till det material som vi samlat in och vad de ansvariga på Hedlunds Hus AB efterfrågade. Detta resulterade i en lista med prioriterade funktioner och innehåll, som vi sedan utgick ifrån vid utveckling av webbplatsen. Vid utveckling av webbplatsen togs även hänsyn till det material som vi samlat in om webbutformning/design. Att använda sig av ett användartest i förstudiefasen tycker vi är ett bra sätt för att få fram vad användarna efterlyser och inte vad vi som webbutvecklare själva tror att användarna behöver.

    Build it and they will come?: Inhibiting factors for reuse of open content in developing countries2009In: Electronic Journal of Information Systems in Developing Countries, ISSN 1681-4835, E-ISSN 1681-4835, Vol. 37, no 5, p. 1-16Article in journal (Refereed)
    Abstract [en]

    Open content has the potential to change the playing field when it comes to every individual’s right to education. Development of new course content is both expensive and time consuming and open content can help educational organizations to deal with these problems by offering free-to-use educational resources. Despite the benefits of open content the usage is very low in developing countries and understanding why content developers choose not to use open content is the first step towards finding a solution to the problem. Which inhibiting factors for reuse do content developers in developing countries experience with open content? To answer the question interviews, questionnaires and observations have been made with content developers from Bangladesh, Sri Lanka and from UNESCO Open Training Platform. Findings show that many of the inhibiting factors with reuse of open content do not necessarily relate to the actual content. Educational rules and regulations, lack of infrastructure, teaching practices and traditions etc. are major obstacles that need to be overcome if the usage of open content should increase.

    Students’ use of one to one laptops: a capability approach analysis2013In: Information Technology and People, ISSN 0959-3845, E-ISSN 1758-5813, Vol. 26, no 1, p. 94-112Article in journal (Refereed)
    Abstract [en]

    Purpose - We evaluate effects of students’ 1:1 laptop use from a capability perspective by investigating increases and decreases of students’ opportunities and choices. We investigate changes that have taken place and how these changes enable or restrict students to do and be what they desire.

    Design/methodology/approach – We undertake an interpretive case study based on group interviews and questionnaires. Sen’s capability approach is used as theoretical framework and has informed the data collection and the analysis.

    Findings – 1:1 laptops in schools have provided students with new opportunities and choices, but also restricted others. An evident opportunity is the equalization of access to computers. Other opportunities relate to schoolwork efficiency and increased access to information. Gains also include the use of different media for overcoming disabilities or to fit individual learning styles. Regarding students’ well-being, a “fun” learning environment is mentioned. However, the “fun” is often about playing games or using social media – something which diverts the students’ attention from the learning. Students also find that they are less social, too computer dependent, and that they miss using pen and paper. Additionally, health issues such as back problems and headaches are reported, as well as an increased risk of being robbed.

    Originality/value – Most research on 1:1 laptops in education focuses on easily quantifiable measures and reports from a teacher perspective. We take a broader approach and investigate the impact 1:1 laptops have on students’ well-being and agency.

    Capability outcomes from educational and ICT capability inputs: an analysis of ICT use in informal education in Kenya2014In: Electronic Journal of Information Systems in Developing Countries, ISSN 1681-4835, E-ISSN 1681-4835, Vol. 61, no 1, p. 1-17Article in journal (Refereed)
    Abstract [en]

    In the field of Information and Communication Technologies for Development (ICT4D) ICT use in education is well studied. Education is often seen as a pre-requisite for development and ICTs are believed to aid in education, e.g. to make it more accessible and to increase its quality. In this paper we study the access and use of ICT in a study circle (SC) education program in the south coast of Kenya. The study is qualitative reporting results based on interviews and observations with SC participants, government officers and SC coordinators and teachers. The study builds on the capability approach perspective of development where individuals’ opportunities and ability to live a life that they value are focused. The aim of the study is to investigate the capability outcomes enabled through the capability inputs access and use of ICT in education as well as the factors that enabled and/or restricted the outcomes. Findings show that many opportunities have been enabled such as an increase in the ability to generate an income, learning benefits, community development and basic human development (e.g. literacy and self-confidence). However, conversion factors such as a poorly developed infrastructure and poor IT literacy prevent many of the individuals from taking full advantage of the ICT and the opportunities it enables.

    SCORM from the perspective of the course designer: a critical review2007Conference paper (Refereed)
    Abstract [en]

    The introduction of e-Learning opens new possibilities and new ways of delivering courses. Learning objects can be used and reused in educational contexts to educate students, employees, administrative officers and citizens. In later years Sharable Content Object Reference Model (SCORM) developed by Advanced Distributed Learning (ADL) has more or less become a de-facto standard for creating learning materials that can be used in different learning management systems (LMS).There are many scientific papers that deal with the benefits of e-Learning from a learner’s perspective, or from a strictly economical point of view. In this paper we critically evaluate which benefits and drawbacks a course designer in a university setting can have from using the SCORM standard to deliver a course to the students. We use scenarios to test what benefits and drawbacks can be observed by setting up a course on an LMS with and without the use of the SCORM specification.Our findings show that for a course designer, advantages with SCORM are possibility of reuse, use of metadata and possibility to sequence the learning path of the learner. The most important drawback for a course designer is the lack of flexibility when using SCORM. Another major drawback is structure rigidity. In order to fully be able to use the potential of SCORM the course design and content should not be changed after the course is started. This might have negative impact on the possibilities to design a university course if the field of study is volatile, like many ICT-related topics are.

    Open content use in Bangladesh and Sri Lanka: context flexibility as an enabler for reuse2009In: Workshop proceedings: 2nd Annual SIG GlobDev Workshop, 2009, p. Paper 11-Conference paper (Refereed)
    Abstract [en]

    Free-to-use learning material, open content (OC), is ascribed the potential to change the playingfield in regards to every individual’s right to education. OC is, however, not much used indeveloping countries. The aim of this paper is to study how actors involved in contentdevelopment affect reuse of OC. Actor-Network Theory (ANT) concepts are used to describecontent development processes in two cases (in Bangladesh and Sri Lanka). Findings show thatthere are content properties that need to be flexible and adaptable for it to be used. The propertiesmust not only fit with students and content developers, it must also be adaptable to fit with theeducational organization and the technologies used for dissemination. Since there are manyactors and properties that must be aligned it is unlikely that fully context independent OC can bedeveloped. For OC to play a role for development the focus has to be on developing flexiblecontent that easily can be adapted to different contexts.

    Development, capabilities and technology: an evaluative framework2011In: Proceedings of the 11th International Conference on Social Implications of Computers in Developing Countries: Partners  for  Development  -­  ICT  Actors  and  Actions, 2011Conference paper (Refereed)
    Abstract [en]

    In this paper we present a framework to be used for evaluation of Information and Communication Technology for Development (ICT4D) projects. The framework is based on Sen´s notion of development as freedom where human capabilities and functionings are seen as key aspects to development. Sen´s capability approach presents an alternative way of seeing and evaluating development (alternative to more traditional ways of measuring development). The approach is based on expanding freedoms, or eliminating unfreedoms, for people so that they can live a life that they have reason to value. Even though Sen is referenced a lot in ICT4D literature the analysis rarely goes further then stating that Sen presents an alternative to traditional ways of development. Reasons can be that the capability approach does not specifically mention technology, in addition to the lack of guidelines presented by Sen on how to use the framework. The aim of this paper is to operationalize the evaluation process and to include a clear role for technology in Sen´s capability framework. The framework is validated with a case on distance education from Bangladesh.

    A Framework for Understanding the Link Between ICT and Development: How Affordances Influence Capabilities2016In: Proceedings of SIG GlobDev Ninth Annual Workshop, Dublin, Ireland, December 11, 2016, 2016Conference paper (Refereed)
    Abstract [en]

    Understanding the role of ICT in development is at the core of the ICT4D field. However, while most agree that ICT do contribute to development, the question of how is still not fully explored. In this research-in-progress, we propose a framework that combines two theoretical lenses, the choice framework (that is based on the capability approach) and affordances, to increase our understanding of ICTs role in the development process. The capability approach considers development as freedoms for people to live the lives they have a reason to value. The affordance theory describes action possibilities allowed by material properties, thereby allowing the examination of how individuals explore material properties of information systems with the objective of enhancing their capabilities. We argue that, by combining the choice framework with affordances we can better explain the role of ICT in the development process, and explain how individuals’ agency and social structures influence their ability to perceive affordances in their interaction with the ICT.

    The capability approach as a tool for development evaluation: analyzing students' use of internet resources2012In: Information Technology for Development, ISSN 0268-1102, E-ISSN 1554-0170, Vol. 18, no 1, p. 23-41Article in journal (Refereed)
    Abstract [en]

    Internet resources have been ascribed transformative powers in the development of educational organizations and students in developing regions. However, most development projects relating to Internet resources focus on publishing material without much analysis of the actual use. The question then is how we can go deeper in our analysis and study actual development outcomes. The analysis in this paper is based on Amartya Sen’s Capability Approach where both the means and ends are evaluated. The research question is “What are the benefits of using Amartya Sen’s Capability Approach when evaluating development outcomes?”. We answer the question by evaluating what capabilities and functionings Internet resources can enable for students in higher education. Findings show that the Capability Approach enables us to gain a deeper understanding of why and how development outcomes are achieved. We are also able to follow the development process from the intervention to the realized outcomes.

    Kan applikationer med kartkomponenter konstrueras enligt designmönstret Model-View-Viewmodel?: En fallstudie i vilka problem som uppstår vid implementering av kartkomponenter i applikationer som bygger på tekniken Windows Presentation Foundation och designmönstret Model-View-Viewmodel2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In object-oriented programming, established approaches are often used in order to solve problems. One such approach is the Model-View-ViewModel (MVVM) design pattern, which is used to separate the graphical user interface from the underlying logic of an application. It is commonly used in applications based on the technology Windows Presentation Foundation (WPF).

    In applications where map components are used (software components that display maps to the user) it may be difficult to apply the MVVM design pattern, depending on how the map component is constructed.

    In this study, three map components are tested in order to evaluate if problems arise in the implementation of these map components in an application based on the technology WPF and the MVVM design pattern. In cases where problems arise, the necessary changes required to solve the problem are also described.

    The tested map components are TatukGIS, SharpMap and MapSUI. The results of the testing show that none of the map components have a built-in ability to create data bindings between the view and the viewmodel, which is required in order to comply with MVVM. For all map components a possible solution to the problem is implemented and discussed.

    Jämförelse av NoSQL-databas och SQL-baserad relationsdatabas: En förklarande studie för när NoSQL kan vara att föredra framför en relationsdatabas2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With the explosive development of the mobile world, web applications and Big Data, new requirements for storage capacity and speed of database systems have arisen. The traditional relational database that has long dominated the marked has received competition because of its lack in speed and scalability. NoSQL is a collective name for databases that are not based on the traditional relational model. NoSQL databases are designed to easily expand their storage capacity while delivering high performance. NoSQL databases have been around for decades but the need for them is relatively new. Our partner expressed a desire to know what differences exist between NoSQL and the traditional relational database. To clarify these differences, we have answered the following questions in this work:  When can a NoSQL database be preferred to a relational database?  What are the differences in database performance? In order to answer these questions, a literature study has been conducted together with experiments where we test which performance differences exist between the selected databases. Performance tests have been performed with the benchmarking tool Yahoo Cloud Serving Benchmark, to verify or falsify the enhanced performance of the NoSQL databases. The hypotheses were falsified in both NoSQL databases. The results showed that the relational database performed better than the cloud based NoSQL databases, but also that the relational database performance deteriorates when the load increased. The results of the experiments are combined with the literature study and together answer our questions. The conclusion is that no database performs better than another one, it is the requirements of the data to be stored. From these requirements, analyses can be made to draw conclusions about what kind of database is preferable.

    Vägnät och busslinjenät - en förutsättning för ledsagningstjänsten Navigator2004Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [sv]

    Detta examensarbete har genomförts med Institutet för transportforskning (TFK) som uppdragsgivare. TFK har gjort en förstudie som behandlar en IT-baserad ledsagningstjänst, Navigator, som ska guida synskadade till närmaste busshållplats för vidare färd i kollektivtrafiken. Synskadade som reser med kollektivtrafiken behöver en annan typ av stöd för sin resa än vad en seende person behöver. Bland annat behöver de få information på ett ickevisuellt sätt. Det kan t.ex. innebära att få information om vilken tid bussen anländer till hållplatsen, uppläst via en hörsnäcka. Information om vägnät och om busslinjenät är viktiga förutsättningar för att Navigator ska fungera tillfredställande. Målet med den här rapporten har varit att undersöka om det går att få de två referenssystemen NVDB:s vägnät och Dalatrafiks busslinjenät, att samverka. Vi har kommit fram till att det finns möjligheter att genomföra detta då vägens noder och referenslänkar samt busshållplatser är koordinatsatta. Då det är viktigt för synskadade att bli navigerade efter en så säker väg som möjligt är det nödvändigt att information om cykel- och gångvägar sammankopplas med vägnätet och busslinjenätet. Den informationen finns idag hos kommunerna. Vi har även gett ett förslag på en systemarkitektur för hur Navigator bör utformas för att uppfylla målet med rapporten.

    Abstract [en]

    Every day thousands of invoices are handled in Swedish organizations, but not everyone has the option or ability to use mobile devices for this purpose. The need exists, but the area is unexplored. This work has been carried out with the purpose of developing guidelines for how a useful and effective mobile application for certifying invoices should be designed that is both easy-to-use and at the same time provides the basis a user needs to be able to make the right decision when certifying an invoice. During the work, Design and creation has been used as a research method and Prototyping as a development method. Through interviews with users of a billing system, a first number of guidelines were developed. These guidelines were used to create three different prototypes that focused on meeting different parts of the guidelines. The prototypes were subjected to usability testing, where the test subjects then talked openly during unstructured interviews what they liked about the prototypes and what problems they experienced. The data collected through these tests and interviews could then be used to create a revised and final list of guidelines. Using the final guidelines, a fourth prototype could be developed.

    eNOSHA - the design and development of a learning object repository2010In: The International Journal on Advances in ICT for Emerging Regions, ISSN 1800-4156, Vol. 3, no 1Article in journal (Refereed)
    Abstract [en]

    This paper describes the development of an open source Learning Object Repository (LOR), named eNOSHA (eLearning Neutral Object Storage with a Holistic Approach.), at University of Colombo School of Computing (UCSC), Sri Lanka. The e-Learning Centre (eLC) at UCSC has been developing learning content for a nationwide e-Learning Bachelor of Information Technology degree (eBIT) and a preparatory programme for the eBIT program (The Foundation in Information Technology, FIT). Since eBIT started in 2002, a lot of learning content has been developed in-house and there was a need for a repository to support storing and reusing of learning content. The aim of the paper is to present the development of eNOSHA in regards to three key concepts, flexibility, reusability and user-friendliness. Based on a requirement analysis carried out in December 2008, a plan was drafted for the development and implementation of the system. A participatory approach was used where users have been involved in the design, evaluation and implementation. Based on the testing of the system we gained a positive response regarding the searchability and reuse of content. Tests have, however, shown that additional features are needed to be implemented to improve the usability of the system, Even though the system has been developed based on the needs of UCSC, one of the objectives has always been to make it context independent. Internal tests conclude that the system is flexible enough to work in different contexts but the design may need some minor changes once tested in other organizations or cultures.

    Samarbete i agila systemutvecklingsprojekt: Vilka mänskliga faktorer påverkar samarbetets effektivitet?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Human factors influence how people interact and communicate with each other. Agile system development work consists of relationships, interaction and cooperation between people. These aspects impact the system development project´s results. However, often in system development there is more focus on the technology itself than on the social aspects, where human factors appear to be a decisive factor, in many cases for the project's end result.

    The purpose of this study is to describe what human factors that can lead to more efficient cooperation in agile software development projects, and to describe how agile system development looks like at Trafikverket.

    Trafikverket wished this study to be implemented as the study’s results may help to reduce the number of less successful systems development projects at Trafikverket.

    The main research question in this work is: What human factors are important to make cooperation between customers and developers of agile software development projects more efficient?

    A case study was conducted at Trafikverket. Data collected from seven semi-structured interviews followed up by questionnaires and document studies was used for the analysis. Conclusion’s suggests that in order to make cooperation between customers and developers in agile system development projects at Trafikverket more efficient five human factors as communication, trust , leadership, knowledge and motivation should be focused.

    Samarbete i agila systemutvecklingsprojekt: Vilka mänskliga faktorer påverkar samarbetets effektivitet?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Human factors influence how people interact and communicate with each other. Agile system development work consists of relationships, interaction and cooperation between people. These aspects impact the system development project´s results. However, often in system development there is more focus on the technology itself than on the social aspects, where human factors appear to be a decisive factor, in many cases for the project's end result.

    The purpose of this study is to describe what human factors that can lead to more efficient cooperation in agile software development projects, and to describe how agile system development looks like at Trafikverket.

    Trafikverket wished this study to be implemented as the study’s results may help to reduce the number of less successful systems development projects at Trafikverket.

    Mobila IT-tjänster och Intelligenta transportsystem (ITS) - framtidsperspektiv 2009 och konsekvenser för Vägverket2004Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [sv]

    Uppdragsgivare till detta examensarbete var Vägverkets ITS-avdelning. Vägverket ska vara en möjliggörare för tjänster inom ITS-området, och detta arbete beskriver de mobila ITtjänster inom ITS som tros finnas år 2009. Det är också viktigt att se hur den nationella vägdatabasen, NVDB, möter de framtida kraven från de mobila IT-tjänsterna. Detta eftersom NVDB är en grunddatabas över det data Vägverket tillhandahåller och möjliggör utveckling av mobila IT-tjänster och det är därför viktigt att den innehåller korrekt och uppdaterad data. Under detta arbete har jag jobbat med två metoder, litteraturstudier och kvalitativa intervjuer. Litteraturstudier har jag använt för att sätta mig in i Vägverkets ITS-strategi, mål, pågående ITS-projekt i Sverige och Europa och framtidsvisionärers idéer om framtidens samhälle och ITS. Intervjuerna gjorde jag med personer som arbetar inom ITS eller IT, för att få deras synpunkter om möjliga framtida mobila IT-tjänster inom ITS. Resultatet pekar på att de framtida mobila IT-tjänsterna kommer vara positioneringstjänster av olika slag. Många anser idag att det är svårt att få information om grundläggande vägdata, som t.ex. köer, olyckor och vägbeskrivning. Utrustningen som kommer att användas tros av majoriteten av de intervjuade att vara mobiltelefonerna, men de kommer vara mer avancerade än de är idag. För att förbättra NVDB för att få igång tjänsteutvecklingen är det viktigt att alla kommunala och statliga vägar finns med, vilket det inte gör idag. Dokumentationen kring NVDB ansågs också komplicerad.

    Möjligheten till att utveckla en generiskt användbar applikation för e-guider - The possibility to develop a generic useful application for e-guides2011Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    En e-guide är ett fenomen som kan ge mervärde för besökaren. Det innebär en övergång ifrån en mänsklig guide till en digitaliserad. Det har tidigare skapats e-guider som inte har haft de tekniska aspekterna som krävs för att kunna framföra informationen till besökaren på det sätt utvecklarna och andra inblandade har önskat. Vi har undersökt och utvärderat en av dessa eguider för att skapa en prototyp för en e-guide över Elsborg, som är en del av Världsarvet Falun. Prototypen utgår ifrån smartphones och operativsystemet Android. Utifrån tidigare och nutida eguider och prototypen, har vi analyserat resultaten och därigenom undersökt möjligheten för att skapa en generisk arkitektur, i form av en applikation för en e-guide som ska kunna appliceras på olika sammanhang oberoende av dess innehåll. Våra efterforskningar har dock visat att det är svårt att skapa en så pass generaliserad mall att den direkt går att implementera utan vissa justeringar.

    eTjänster som social interaktion via användning av IT-system: en praktisk teori2007Doctoral thesis, monograph (Other academic)
    Abstract [sv]

    Företeelsen eTjänst baseras på att IT-system används så att tjänsteleverantörer tillhandahåller tjänster till kunder utan att möta dem ”ansikte-mot-ansikte”. eTjänsterna förväntas öka i mfattning i samhället. Därför diskuteras eTjänster i ökande grad inom både forskningen och praktikfältet, och därför är det viktigt att kunna analysera eTjänster vid utvärdering och utveckling av IT-system. Ett problem är dock att det saknas ett utvecklat perspektiv på eTjänster som kan användas för att förstå dem på ett meningsfullt sätt. I existerande perspektiv betraktas vanligen eTjänster som tekniska företeelser vilket gör att de sociala relationer som tjänsterna bygger på inte uppmärksammas. Ett annat problem är att kundperspektivet inte beaktas i tillräckligt hög grad. Detta medför att eTjänster främst betraktas som ett stöd för befintlig tjänsteverksamhet eller för att tjänsteleverantören ska kunna automatisera sin verksamhet och kunderna utföra arbetet själva genom s.k. självbetjäningstjänster. Avhandlingens forskningsbidrag utgörs av en praktisk teori om eTjänster, som både är tillämpbar och leder till en meningsfull förståelse när den används som stöd vid analyser av eTjänster. Den praktiska teorin baseras på grundsynen att eTjänster är social interaktion via användning av IT-system och att kommunikation och kundnytta är i förgrunden. Den bygger också på en bredare syn på IT-användning än som ett sätt att skapa självbetjäningstjänster. Den praktiska teorin om eTjänster består av ett regelverk som ger stöd för att 1) avgöra när det är meningsfullt att beskriva en företeelse som en eTjänst, 2) beskriva hur en eTjänst kan analyseras samt 3) beskriva hur ett flertal eTjänster kan samexistera med varandra i de skärmdokument där de presenteras. Forskningsbidraget har utvecklats genom praktisk utforskning, med en multigrundad kvalitativ ansats och genom en successiv kunskapsutveckling. Avhandlingen har sina teoretiska utgångspunkter inom områdena informatik, sociologi och tjänstemarknadsföring.
