    Gränssnittets betydelse i främjandet av kognitiv bearbetning: En undersökning om praktisk utnyttjande av designprinciper i skapandet av webbgränssnitt2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många webbgränssnitt idag misslyckas med att möta användarnas behov och blir därför bristfälliga gällande användarvänligheten. Detta leder till att användarna begår stora misstag och anstränger sig vid användningen av webbaserade system. Visuell design och struktur i ett gränssnitt spelar en stor roll i hur användarna förstår sig på och tolkar ett gränssnitt då de avser hur olika beteenden och information kommuniceras till användarna. I denna studie undersöks hur visuell design, struktur och användbarhet i ett gränssnitt underlättar användarnas kognitiva bearbetning av information vid utförande av komplexa uppgifter. Studien har utförts genom ett uppdrag för Ahltorpmedia AB, som skapar lösningar för bl.a. webbplatser, webbaserade system och e-handel. Uppdraget har varit att förbättra en av deras egen utvecklade tjänst Nuhet som är bristfällig gällande områdena ovan.

     

    Först har en heuristisk utvärdering av Nuhets befintliga gränssnitt samt sju intervjuer med tjänstens befintliga- och potentiella användare inom huvudområdena visuell design, struktur och kognitiv bearbetning av information gjorts. Resultaten från intervjuerna och utvärderingen har använts för att bilda en persona varefter fokusområden för prototyparbetet har skapats. Sedan har en prototyp på Nuhets nya utseende och en ny funktionalitet skapats. Designprinciper för användbarhet samt gestaltlagar har nyttjats i skapandet av Nuhets nya gränssnitt.

     

    Utifrån de metoder som har genomförts i detta examensarbete har det framkommit att det beror på flera faktorer gällande hur användarnas kognitiva bearbetning av information underlättas med hjälp av visuell design, struktur och användarvänlighet. Dessa är då en bra struktur, gruppering och organisering av innehåll i ett gränssnitt. Dessutom är det tydliga kontraster, bra färgval och standardisering som underlättar den.

    Molnbaserade affärssystem: Viktiga aspekter vid övergång till molnet2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det saknades teori kring vilka aspekter som var viktiga för potentiella kunder att väga in i ett beslut om övergång till molnbaserade affärssystem. I undersökningen har vi samlat tidigare forskning kring molntjänster generellt och sedan jämfört den med empiri från respondenter med erfarenhet av molnbaserade affärssystem. På så sätt har vi försökt koppla tidigare forskning och undersökt huruvida den är applicerbar på vår studie. Vi kom fram till att det framförallt är aspekter rörande säkerhet, ekonomi och affärsstrategi som kunder bör vara medvetna om när de planerar en övergång till molnbaserade affärssystem. Rörande säkerhet fann vi att det är viktigt att tänka på hur den fysiska lagringen sker och säkerhetsrutiner kring vem som handhar data och hur den säkerhetskopieras samt vem som äger datan. Ekonomiskt kan beslutet om en övergång påverkas av molntjänsters olika prismodeller, hur kostnader skiljer sig mot lokalt installerade system samt potentiellt dolda kostnader. Slutligen kan det affärsstrategiskt finnas avgörande aspekter i hur system interagerar med varandra, hur anpassad en tjänst är till mobila enheter samt att molntjänster enkelt kan skalas upp i storlek vid behov.

    The impact of Digital Technologies on Academic Libraries: a study in Greece2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Purpose: This study explores both library users’ and librarians’ experiences, benefits, and challenges depending on the implementation of digital technologies in academic libraries. The research has been taken place in two Greek academic libraries; In the Panteion University Library and in the Central Library of T.E.I. of Athens.Approach: Two research questions were developed for this research to be conducted and a sample size of 55 respondents (39 library users and 16 librarians) of the Panteion University Library and Central Library of T.E.I. of Athens, was evaluated.Findings: From the findings of the study, it was concluded that the general perception of both library users and librarians towards digital material and E-resources and services of the Panteion University Library and Central Library of T.E.I. of Athens, is satisfactory. Library users were satisfied with the convenience of digital material, the availability of E-resources provided by both academic libraries such as World Wide Web, WIFI, and online databases. They were not satisfied with library technology (i.e., computers) and library staff. Besides, results showed that services such as e-mail and Open Public Access Catalogue were used more often. Librarians were less satisfied with the digital library system, the limited personnel, and the financial funds for academic libraries in general.Implication: The results of this research have implications in the stakeholders of an academic library including the institutional management, the library administration, the librarians, the library users, the researchers, the community at large, and others.Value: This paper identifies critical issues related to the utilization of digital technologies and digital material; their benefits and challenges faced by librarians and library users as well as their effective operation from academic libraries in this information age.

    Exploring knowledge sharing in the Requirement Engineering phase of globally distributed Information Systems development: Perceived challenges and suggestions for improvement2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Master thesis explores the knowledge sharing that takes place during the requirement engineering phase of globally distributed information systems development. In recent years, due to globalization, information systems development activities have become increasingly distributed across different geographical locations. Requirement engineering is an important and knowledge intensive phase in the development of information systems. Requirement engineering is the process of identifying, analyzing, documenting, validating and managing the requirements of a system. Effective and efficient knowledge sharing during the requirement engineering is vital for the successful development of information systems. However, the global distribution of the stakeholders has affected knowledge sharing during requirement engineering in various ways making it more challenging.

     

    Drawing on the theories of knowledge sharing within the field of information systems, this interpretive research study aims at exploring stakeholders’ perceptions about the challenges met during the knowledge sharing in requirement engineering phase of globally distributed information systems development projects. More specifically, this Master thesis explores the perceived challenges and generates a list of suggestions to overcome the challenges by conducting qualitative semi-structured interviews among the key stakeholders, both customers and business analysts.

     

    The findings indicate that the knowledge sharing is influenced by challenges such as cultural differences, language barriers, communication issues, coordination issues arising from multiple stakeholders, time difference and difficulty in sharing tacit knowledge in the globally distributed settings. Participants’ suggestions for overcoming these challenges include cultural trainings, kick off meetings, language trainings, use of translator, face-to-face communication and interaction, video conferencing, scheduling important meetings in the common suitable timings, identification of the main stakeholders, having a mediator and making close observations with face-to-face interactions.

    Abstract [en]

    This study gives a brief description of paper-based record and the adoption of ICT, which brought the introduction of Electronic Health Record System (EHRS) in Sweden, the challenges facing EHR in the health care sector around the world and what immigrants and newcomers who just arrived in Sweden knows about the privacy,  rights and the policies that protect their privacy and data system, these could cause them not having enough confidence in electronic health record system, they could also be worried about their information been exposed or disclosed by their healthcare providers, this call for the confidentiality, security and privacy of EHR System. The aim of this study is to explore immigrants and newcomers as users of electronic health record system by setting interview questions and focus group to help the researcher to understand their knowledge of what they know about the privacy of EHRS and what they know about the policies health care providers follow to protect patient’s privacy and data. It is very important for them to know their rights and the rights that protect their privacy and data from been shared or disclosed.

     

    The study also talked about the existing implications facing EHRs, comparison of both systems was shown in table 1 of this study. The necessity for a proper protection of patient data was discussed and recommendation was made towards having a great and a working electronic health record system.

    Information and Communication Technologies in Support of Remembering: A Postphenomenological Study2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to study the everyday use of ICT-enabled memory aids in order to understand and to describe the technological mediations that are brought by them (i.e. how they shape/mediate experiences and actions of their users). To do this, a post-phenomenological approach was appropriated. Postphenomenology is a modified, hybrid phenomenology that tries to overcome the limitations of phenomenology. As for theoretical framework, ‘Technological Mediation’ was adopted to conduct the study. Technological Mediation as a theory provides concepts suitable for explorations of the phenomenon of human-technology relation.

    It was believed that this specific choice of approach and theoretical framework would provide a new way of exploring the use of concrete technologies in everyday life of human beings and the implications that this use might have on humans’ lives. The study was conducted in the city of Växjö, Sweden. Data was collected by conducting twelve face-to-face semi-structured interviews. Collected data was, then, analyzed by applying the concepts within the theoretical framework – Technological Mediation - to them.

    The results of this study provided a list of ICT-enabled devices and services that participants were using in their everyday life in order to support their memory such as: calendars, alarms, notes, bookmarks, etc. Furthermore, this study resulted in a detailed description of how these devices and services shaped/mediated the experiences and the actions of their users.

    Digital Wall: The University’s learning and information space2017Student paper other, 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A North American university is engaged in a large transformation project involving the wholeorganisation. Students, Lecturers, departments and additional questions from the shared leadership team are engaging in defining the services offered, in particular from the university library and its associated sub-services. It is an exciting time for the University as it seeks to not only define its services but also how these can be created and consumed.There are many aspects to this re-organisation and many items to be addressed. In this report,we look at the current situation at the University, as well as taking into account the aspirations of the stakeholders. We start by drawing out a Rich Picture, part of Soft System Methodology (SSM) (Checkland, 1981) which we use in order to spot opportunities that are available for further exploration. Much of the information that we use comes from material supplied by the University itself as well as interviews with the Head of Library services and Head of Library IT. We look indepth at how SSM assists in this process of evaluation through its focus on participation and how it may assist us to understand the many different perspectives collected in our research. SSM consequently assists in defining problems with solutions to any areas that have drawn our attention. Following the evaluation of collected data, discussions and our own observations, we identify that a digital wall that is being proposed for the redesigned library presents an opportunity to explore possibilities for exploitation of this technology. Further research on other digital walls such as Brisbane’s Cube (Abdi et al, 2014), and Auraria Library’s Discovery Wall(Burch, 2016) shows some of the uses that these walls have been put to and how the Institutions use them. We then use a number of models to evaluate the data that we collected on digital walls and from the North American University and analyse it in order to inform our thinking. These models can be used independently or collectively to evaluate data from different perspectives. As such we were able to look at problems and solutions from the perspective of many of the actors involved in shaping the future library services. These models and results are discussed in the report. Finally, we take our results and make a number of proposals for the North American University digital wall along with the relevant justifications at the end of this report.

    Utbildning vid systemimplementering: Väsentliga faktorer att ta hänsyn till2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Utbildning i samband med systemimplementering är enligt tidigare forskning ett viktigt men åsidosatt ämne som behöver studeras mer i detalj. Den här uppsatsen undersöker vilka faktorer som är väsentliga vid en utbildningssituation i samband med införandet av ett nytt system i en kommunal organisation. Studien belyser faktorer som uppkommit i insamlingen av empiri samt de faktorer som framkommit från tidigare forskning och teoretisk bakgrund. Idag finns det ingen standardiserad modell för hur en användarutbildning bör se ut. Således presenteras de viktigaste faktorerna som ger en indikation på hur en utbildning påverkar implementeringsresultat och hur en bra användarutbildning bör se ut.

    Knowledge triangle pedagogy: a global software development project connecting university-company-students2016In: Innovative technologies and didactics in teaching / [ed] Wladimir bodrow, Yury Rogozov, Berlin: Conference Print , 2016, 11-18 p.Conference paper (Refereed)
    Abstract [en]

    This paper presents the experiences of setting up a knowledge triangle project in the software development field as an approach to teaching in the area of information systems and information technologies. The case includes an international dimension of the IT industry as it interconnects several countries. The cooperation between company and university is a pedagogical tool for creating an educational situation which conveys motivation and broad perspectives to the student. However, this brings in a number of problems and a generally higher level of complexity. This paper explores a case that illustrates the complexities and presents a generic model of a setup for a knowledge-triangle-based educational situation. Its model adopts an increasingly important aspect of IT education, namely how to prepare students for the globalized nature of the IT industry. The final discussion focuses on issues concerning the use of knowledge triangle thinking, including complexity, measurements, pedagogy and organization.

    Abstract [en]

    Self-care is important for heart failure patients. However, what are the views of patients on their situation when it comes to realizing self-care? The aim of the paper is to investigate the self-care needs of HF patients, by understanding the issues they embrace in their self-care processes. In this paper we make a review of 17 interviews and make a classification of what the needs are for possible information technology support systems. Based on the analysis of these interviews, we identify the diversity of needs in support of activities related to different background conditions and the dynamics of change of learning and changes in the heart failure condition. The contribution of the paper is a framework for understanding the diversity of needs and the specific situations of this group of patients.

    EDI AND GREEK SMES. A MULTIPLE CASE STUDY IN THE CONTEXT OF TECHNOLOGY, ENVIRONMENT AND ORGANIZATION.2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Electronic Data Interchange (EDI) holds the potential to improve contemporary business operations, which are redefined frequently based on the demands of global competition. There are numerous EDI systems, which an enterprise can choose to adopt in order to meet its needs and goals. International literature demonstrates a variation of views regarding the adoption of new technologies, which differ according the size of each organization along with internal and external impediments and determinants. The use of EDI worldwide has gained a positive acceptance by commercial companies, industries and service providers, followed by rapid adoption mainly in the processes of large organizations. Conversely, the predictions of previous years’ studies have not been materialized to the expected extent. In Greece in particular, there is low penetration and a reluctance to adopt EDI technologies by Small and Medium Enterprises (SMEs). This study is based on the theoretical framework of Technology, Organization and Environment (TOE). A qualitative multiple case study research design has been used, in order to provide further insights on the factors that affect the decision of Greek SMEs in adopting EDI technologies. The significance of the perceived direct and indirect benefits, the effects of the perceived financial cost and technical competence and the importance of industry and government pressure on corporate level, are analyzed and discussed. An empirical support of the low penetration of EDI in the Greek SMEs' community is also provided. This research contributes in the existing knowledge about EDI adoption decisions regarding Greek SMEs by providing a variation of views, further insights on how Greek SMEs behave and react during the current economic recession and a new cost factor that emerged within the analysis of multiple cases. Avenues for future research are recommended in order to expand this study's findings in the field of corporate IT innovation.

    Collboard: Fostering new media literacies in the classroom through collaborative problem solving supported by digital pens and interactive whiteboards2013In: Computers and education, ISSN 0360-1315, Vol. 63, 368-379 p.Article in journal (Refereed)
    Abstract [en]

    Education systems worldwide must strive to support the teaching of a set of New Media Literacies (NMLs). These literacies respond to the need for educating human capital within participatory cultures in a highly technologized world. In this paper, we present Collboard, a constructivist problem solving activity for fostering the development of specific NMLs in classrooms: collective intelligence, distributed cognition and transmedia navigation. Collboard encompasses successive individual and collaborative work phases that prompt active student participation and engagement. It integrates digitally augmented appliances, namely, digital pens as a means to support individual work, and interactive whiteboards as a collaborative knowledge construction space. We report on the conceptual design of Collboard, its different technological and software components, as well as our findings from experiences we conducted in a Swedish school with 12 students from a 7th grade maths class. Findings from the experience provide an indication that Collboard can be well integrated in classroom teaching, and that it can foster the development of collective intelligence, distributed cognition and transmedia navigation in different knowledge domains.

    Evaluation of University-Library Knowledge Management Practice: Comparative Case Studies from Developing and Developed Countries2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Knowledge management (KM) has become a vital part of the successful development of private and governmental organizations. KM is processed tools and behaviors that participate in the formulation and performance of the beneficiaries of the organization, acquisition, storage and distribution of knowledge. This is to reflect on the business processes and to gain access to best practices with a view to long-term competition and adaptation. In this context, the personal understanding of KM is a key factor in successful employments of KM activities. In this thesis, the level of understanding of knowledge management and the extent of its usage in the university library by librarians was investigated. A comparison study was established between libraries in developed and developing countries. Interviews and observations were performed and the results were analyzed. The results indicate the concept of KM is hardly known, however it is employed to different extent between these counties, the developed countries were by far more successful in utilizing current technology to advance their service and personal expertise with few challenges. Lack of communication, knowledge sharing, and the shortage in the budget was essential in limiting the usage of KM in developing counties. The knowledge derived from this thesis advances an understanding of the importance of KM in library performance, thus presenting the basis for improving libraries in developing countries and advancing libraries in developed countries.

    User Perspective of Privacy Exposure on Facebook: An Examination of Risks Perception Among University Students in Sweden2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Social media become a powerful communication medium for effective online social interaction globally. The use of various social networking sites has integrated into people’s daily lives especially among young adults. Problem arises when personal information is used without individuals’ involvement and relevant privacy risks increased. The main focus for the thesis is to investigate privacy perception and risks knowledge of Facebook usage among university students in Sweden. Based on this focus, the research identifies the key reasons that students decide to use and still use Facebook despite of privacy risks. The study also explores how user perspective of privacy affects the utilization of Facebook. The adopted methodology is qualitative research through the methods of interview and Facebook data analysis among ten young adult students at Linnaeus University in Sweden. As result, the research has identified seven concepts and three special outcomes to answer the research questions. Through the analysis, we have recognized weak perception of privacy risks among university students. Although users claim they are privacy concerned yet large amount of private information is shared on Facebook. The findings have shown that users are somewhat willing to accept certain part of potential privacy risks and personal information usage by different parties, in exchange for benefits and needs of online interaction in today’s modern society. Users believe the shared personal information on Facebook is under control and they can prepare for possible consequences. However, we believe that people’s needs for popular online social interaction outweigh privacy concerns. We suggest that it is significantly important for social networking sites’ users to balance benefits and risks, in order to maintain balanced usage and positive effects of online personal privacy. In the end of the thesis, we have suggested two future research directions based on our research topic.

    Varför Web 2.0?: Modell för praktisk utveckling av organisationers kommunikation, nätverkande och samarbete2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Utvecklingen av webben har sedan den skapades 1989 gått från att bestå av statiska webbsidor till att bli mer interagerande med dess användare. Denna utveckling, som kallas Web 2.0, har på ett naturligt sätt letat sig in i företagssammanhang.

    Denna studie började ursprungligen som ett uppdrag åt myndigheten Trafikverket. Studiens syfte har varit att på ett praktiskt sätt undersöka möjligheterna att utveckla organisationers inom- och interorganisatoriska kommunikation, nätverkande och samarbete med hjälp av Web 2.0- tekniker. Vi beslutade oss för att skapa en tentativ modell för hur organisationer kan gå till väga för att utveckla dessa områden och testa denna mot fallmyndigheten.

    Cook (2008) har skapat en kategoriseringsmodell för Web 2.0-verktyg som han kallar för 4C-modellen. Modellen utgår ifrån de användningsområden verktygen har.

    För att genomföra denna studie har vi använt oss av en deduktiv ansats med en kvalitativ metod. Vi utgick från Cooks (2008) 4C-modell och genom en iterativ process där vi blandade teori med intervjuer utökades modellens praktiska tillämpbarhet.

    Modellen består av en övergripande beskrivning av organisationen, djupdykning i områdena kommunikation, nätverkande och samarbete. Därefter består modellen av en kartläggning av Web 2.0-verktyg samt en SWOT-analys för att sedan rundas av med en slutsats.

    Modellen tillämpades på verksamhetsområdena Investering och Stora projekt på Trafikverket. Resultatet från tillämpningen visade att användandet av Web 2.0-verktyg skulle kunna underlätta introduktion av nyanställda, öka möjligheterna för formellt och informellt samarbete samt förbättrad kunskapshantering. Möjligheterna för organisationer att använda Web 2.0-verktyg underlättas av det faktum att det finns produkter på marknaden som innehåller flera Web 2.0 funktioner, exempelvis Microsoft Sharepoint.

    Feedback från universitetslärare till student: En kvantitativ undersökning av feedback-processen ur ett informations- och kommunikationsperspektiv2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Feedback can be defined as a process where the effect of an action is returned to its source in order to alter future actions. Within educational systems feedback is commonly associated with the teacher’s response to student performance. Previous research shows that the feedback process between tutor and student is a complex one that involves several problem areas. This study aimed to explore, from a student perspective, whether these problem areas exist at Linnaeus University and to describe and analyze existent problem areas with information- and communication theories. The theories used in this study are Shannon-Weavers models of communication, criteria for information quality and Media Richness Theory. The study has been conducted with a quantitative method and a deductive approach, carried out by a survey targeted to students at Linnaeus University. The result/analysis of the study identified problem areas and described them with the selected theories. The conclusion of the study was an answer to the question regarding which problem areas can be identified at Linnaeus University as well as how these problems can be described with the use of the study’s selected information- and communication theories.

    Den avskalade effekten: Om effekten av ett minimalistiskt skrivverktyg och hur det upplevs i en interaktiv användningssituation2017Student paper second term, 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis and report has addressed and focused on identifying the interaction effect that occurs when an information system's interface is scaled off and is minimalistic. This case study is based on a web-based writing tool called Writer. The purpose of the research has been to clarify the personal interaction effect in an interactive usage situation and how it in turn affects the user experience. The theoretical field and framework of the study is Actability , focusing on the interactive action level in connection with The Elementary InterAction Loop . The Elementary InterAction Loop consists of four steps where the user asks, does, gets an answer and then evaluates. In conjunction with the theory, five interaction criteria have been incorporated, which are; Clear Action Repertoire , Intelligible Vocabulary , Action Transparency , Clear Feedback , and Amendability . These five criteria have been the thematization of the empirical work.

    Through both targeted selection and snowball sampling, six journalists/writers have been involved in collecting data. In the method work, user test was performed on the writing tool with tasks formulated in accordance to the five interaction criteria. In the method work, user tests was performed on the writing tool. Thereafter the tasks was formed according to the five interaction criteria from the theoretical framework. All informants evaluated their experience and made thirteen statements based on a user experience questionnaire where concepts such as easy to learn/not easy to learn and effective/ineffective were asked for. Following these two steps in the empirical study, semi-structured interviews were conducted with fifteen questions based on the five interaction qualities. In order to analyze the collected data, the content analysis method was applied which resulted in 25 categories with descriptions and quotes. Based on a content analysis and its results, the categories were then analyzed using the D.EU.PS model and its 18 classes. The analysis resulted in ten interaction effects placed in seven different classes. The result and the ten interaction effects are: Security, Previous references, Terminology, Recognition, Understanding of sequence/action, Perception, Simplicity, Efficiency Availability and Grouping (proximity). Based on personal behavior as a perspective, these effects are the result of a minimalistic writing tool that contributes to a good user experience.

    Det sociala intranätets funktioner: En fallstudie med fokus på användarnas uppfattning och användning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den moderna kommunikationen har medfört verktyg och funktioner som har skapat nya standarder för hur vi kommunicerar både privat och inom organisationer. Tidigare forskning presenteras i studien för att visa vad andra forskare har fokuserat på inom området sociala intranät. Det finns två studier som sträcker sig igenom hela vår uppsats. Den första studien presenterar faktorer som påverkar implementering av ett socialt intranät och som kan påverka användandet. Den andra studien, introducerar begreppet affordance. Ett begrepp som används för att beskriva hur människor utnyttjar ett fenomen beroende på hur de uppfattar och antar vad fenomenet kan göra för dem.

    Studien kan vara av intresse för andra verksamheter och organisationer som har ett socialt intranät och vill få förståelse vad som kan orsaka minskat användande av dess funktioner. Undersökningen har tillämpats på ett fallföretag. Företaget är ett medelstort utvecklingsbolag som finns på flera geografiska platser. Företaget expanderar och fler kontor är på väg att öppna, intranätet är därför en viktig komponent för företagets fortsatta expansion. Detta gör att det interna samspelet av innehåll, kommunikation och aktiviteter är högprioriterat för fallföretaget.

    Syftet med studien är att beskriva varför anställda inte utnyttjar sig av de sociala funktionerna som finns på fallföretagets intranät. För vår empiri valde vi en kvalitativ ansats i form av intervjuer för att besvara uppsatsens frågeställning. Informanter valdes ut efter aktivitet på intranätet och efter arbetsroll. Undersökningen utfördes på fallföretagets huvudkontor.

    Från empirin har vi fått fram olika orsaker som påverkar användandet av fallföretagets intranät. Med hjälp av analysen har vi identifierat att det finns en sammankoppling mellan uppfattning och utnyttjande av sociala funktioner. Analysen visar att det i stort sett förekommer skillnader i alla affordance mellan införandet av vad intranätet syftar till och hur anställda uppfattar och utnyttjar sig av funktionerna. Det har resulterat i att vi har upptäckt ett mönster som vi med hjälp av en cirkelmodell vill öka förståelsen för. Cirkelns syfte är att hjälpa företag att identifiera orsaker/problem som kan finnas i organisationen och som kan påverka hur anställda utnyttjar och använder sig av sociala intranät. Vi har kommit fram till fyra dimensioner som kan undersökas för att förklara och beskriva anställdas uppfattning och användande av sociala funktioner ur ett affordance perspektiv.

    Gör kunden ingen björntjänst: Hur kunder och deras upplevelse kan stödjas i användandet av tjänster i mobilenheter2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien har som syfte att besvara hur en kund använder sig av kundservice som stöd och hur en självservicetjänst i en mobilenhet kan utformas för att ge en positiv kundupplevelse. Nya kunder tenderar att lämna tjänster de inte förstår och motivationen att använda sig av kundtjänst skiljer sig mellan kundgrupper. Som fallstudie har vi undersökt Svenska Spels tjänst Stryktipset. En kvalitativ studie har genomförts där nya ovana kunder i åldern 18-29 deltagit i användartest, observationer har genomförts på traditionell kundtjänst och intervjuer med ombud. Detta har resulterat i en förståelse för problemsituationer i kundupplevelsen, mobilenheten och vilket stöd de olika servicekanalerna ger. Designkoncept har tagits fram som visar på hur detta stöd kan se ut och hur det kan hjälpa kunden i sitt användande. Studien visar på att kunder behöver stöd i att förstå hur en tjänst fungerar, vad målet med tjänsten är och hur kunden bör gå till väga. Genom skapandet av en självservicetjänst kan kunden få ett bra stöd i sitt användande och genom att kunden tilldelas kontroll och får relevant information stärks kundupplevelsen positivt. En Självservicetjänst stödjer nya kunder på ett effektivt sätt innan kunden stöter på problem vilket tar bort negativa faktorer som hjälplöshet och motivationsbrist som gör att kunden kan avsluta sitt användande. En självservicetjänst framstår som ett positivt stöd i användandet av Svenska Spels mobilenhet och kan ge ett bra stöd åt användaren som inte andra servicekanaler kan erbjuda.

    Att använda intranät som informationskälla: En studie kring medarbetares önskemål2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    ”Att använda intranät som informationskälla” är en studie kring den interna företagskommunikationen som sker via intranätet. Studien har genomförts som en fallstudie på ett företag med en, inom Sverige, geografiskt spridd organisation och kommer att fungera som underlag för ett pågående internt projekt. Visionen för projektet är att skapa ett användarvänligt intranät som säkerställer fallföretagets arbetssätt och leder till långsiktig lönsamhet och konkurrenskraft. Intranätet är tänkt att underlätta samarbete mellan personer och avdelningar på geografiskt spridda platser och användas som ledningssystem

    Den kvantitativa enkätundersökningen omfattade 20 frågor som distribuerades till samtliga 213 medarbetare i Sverige inom fallföretaget i form av en länk till en webbenkät. Länken placerades på intranätet och skickades ut tillsammans med ett följebrev via e-post. De 82 inkommna svaren motsvarar en svarsfrekevens på 38%. Undersökningen var uppbyggd utifrån fem frågekategorier där de respektive frågorna är utformade för att svara på:

    -Hur användningen av intranätet ser ut i nuläget,

    -Vad medarbetarna önskar läsa om på intranätet,

    -Vem som medarbetarna tycker ska publicera information och nyheter,

    -Hur medarbetarna önskar att innehållet ska presenteras, formatet på information och nyheter samt

    -När medarbetarna önskar att information och nyheter publiceras.

    Valda teorier i form av bland annat kommunikationsmodellen och DeLone & McLeanmodellen ställdes i relation till den insamlade empirin för analys och utifrån denna analys har vi dragit följande slutsatser:

    - En informationskvalitetsmedvetenhet behöver infinna sig hos ledningen – det som publiceras måste vara genomtänkt för att uppnå den eftersträvade effekten.

    - Ett holistiskt synsätt på den interna kommunikationen krävs – det räcker inte att en viss komponent håller måttet utan standarden måste vara hög på samtliga komponenter för att internkommunikationen ska fungera så som avsikten är.

    Establishing new consulting services in health care organizations: an ANT analysis of patient-centred care2013In: ACIS 2013: Information systems: Transforming the Future: Proceedings of the 24th Australasian Conference on InformationSystems, 4-6 December 2013, Melbourne, RMIT University , 2013, 1-12 p.Conference paper (Refereed)
    Abstract [en]

    A recent trend in health care is patient-centred health, but are health care organizations ready to cope with that change? Changes at the patient level are one aspect but there is a need for reshaping the organization of health care. There is a need to focus much more on prevention care, helping patients to cope and become better self-managers, focusing on the patient process, working together and empowering patients. The aim of this paper is to gain a better understanding of the lack of sustainability over time in two patient-centred care (PCC) projects by using actor network theory (ANT) as an analytical framework. We use case studies from heart fibrillation and heart failure care organizations in a Swedish county council. The cases concern initiatives to achieve better interactions for these patients and organize care to become more patient-centred. Both initiatives have now been partly abandoned in the organization, although research and guidelines recommend such care organizations. The analysis of the different actors dominating the translation process towards a PCC network and of the way they get together in networks reveals that this is a time-consuming process, taking place long after the initial training and PCC implementation activities. We discuss the temporality of stability, the reversible process with chimerical enrolments, and how a complex and changing environment demands constant re-problematization of PCC.  We also include how the understanding of the translation and negotiation process can influence decisions on allocating sufficient time and resources to the process. We shed light on the importance of understanding and managing the organizational change in a PCC project and thus also of when to implement patient-centred e-health solutions.

    Gamification - Samspelet mellan människor och IT: Undersökning av spelmekanismers motivationshöjande effekter2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis is a study to investigate the game mechanics in a selected training application. The study aims to create a greater understanding of why people get motivational effects with the help of information technology. This will be done by examining the users of the example Nike + to find out what features they consider giving them a motivating effect and thus describe the game mechanics these include.

     

    The study uses a qualitative approach to carryout interviews with the users of our example Nike+. The interview questions are based in theory of the field Gamification and previous research on the topic.

     

    The result shows that there are several different game mechanics implemented in Nike +, which has a positive impact on users. The result strengthens the game mechanics informants set positively towards making running a fun form of exercise as well as increased training frequency of our informants.

    Vad har du på menyn?: Designriktlinjer för naturliga interaktioner och mobilitet i en stationär miljö2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today many companies have intranet failing to meet the users need and the most frequent complaint is that users do not find what they are looking for. This leads companies to lose both time and money on having employees that are unable to utilize the system in a sufficient manner, which often leads to expensive educational costs and loss of productivity. The primary reason that information is not found is that there is a lack of a consistent navigation tool that clearly indicates where the user should go to find what he/she is looking for. Design and structure in an interface plays a large role when it comes to how users understand and interpret an interface. However, the difficulty is that it tends to be visually disruptive and provide a cognitive load. Currently are a strong development of mobile devices taking place and questions are raised regarding how these interfaces can be optimized to make it easier for the user. Especially, when it comes to the mobile context and the limitations it causes. To make it easier are designers advised to develop natural interactions which are supposed to ease the cognitive load. This study therefore explores how design principles stemming from natural interactions, together with the mobility, affect the usability and ease of use for work in a desktop environment. The study has been conducted upon request of CLX Networks, a company that provide solutions for, among others, sms, voice and data. The assignment has entailed suggestions of improvements of the company’s intranet menu, which has been considered as inadequate by CLX.

    In this study, a user test of CLX’s current intranet menu was performed as well as five interviews with employees that work and use the system. The interviews concerned the topics of findability, actability, usability and mobile usability. Continuously was a card sorting performed to let the informants themselves visualize a proposed menu. The results from the empirical investigation were used to create an interactive prototype. Design principles from findability, actability, usability and natural interactions have been utilized in the creation of the new menu.

    Based on the investigations performed in this study is it possible to conclude that design principles from natural interactions and the mobility have a positive influence on ease of use concerning the menu in the graphical interface in a desktop environment. The study also confirms that a combination of the two viewpoints, natural interactions and desktop paradigm that facilitate the usage and cognitive load, which previously was troublesome for the employees.

    Internkommunikation vid förändringsarbete: En djupstudie av ett enskilt fall2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den problemformulering som denna uppsats har besvarat har varit hur kommunikations-strategin i ett specifikt förändringsarbete kan beskrivas, samt vilka jämförelser som kan gö-ras mellan kommunikationsstrategin och det teoretiska ramverket. Undersökningen i upp-satsen har baserats på en abduktiv ansats med i huvudsak deduktiv inriktning där kvalitativ och kvantitativ data samlats in från de som varit drivande av förändringen, samt de som varit föremål för förändringen. Datan har analyserats utifrån det teoretiska ramverk som varit unikt för undersökningen. De slutsatser som har dragits visar att kommunikationsstra-tegin varit något reaktiv och anpassats efter de individer som varit föremål för förändringen. Jämförelser med det teoretiska ramverket har visat att kommunikation till största del skett genom direkta samtal, i mötesform, att kommunikation använts som ett sätt att förbereda för förändring, samt att möten använts för att kommunicera de rutiner förändringen inneburit.

    Varumärkesstrategi på webben: Tillämpning av användarcentrerad design för positionering på webben2015Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Purpose: Corporations experience difficulties positioning themselves on the web as a result of not developing their websites in a way that is inline with their overall business strategy. The purpose of this study is to explore how corporations should apply design strategy, based on a user-centered design perspective, to support their overall business strategy on the web.

    Originality/value: This study has identified a knowledge gap in terms of how corporations define and apply design strategy in order to support their overall business strategy on the web.

    Methodology: This study aims to research the application of design strategy by creating a prototype through the use of a user-centered design process. This was done by interviewing experts as well as evaluating websites, in order to explore the domain of a car manufacturers retailers, which was based on the corresponding strategy of leading the visitor to the car manufacturers offerings that are represented by the retailers and their websites. This data collection was the foundation in the creation of a persona and context scenarios that was translated into identified needs that represented the products design strategy. The design strategy in turn was the foundation for the creating phase of the user-centered design process, where iterative design lead to refining framework sketches and an interactive prototype.

    Findings and conclusion: The study which resulted in an interactive prototype shows that user-centered design, which applies design strategy by defining the corporations and the users goals and needs, is an alternative that allows for structured refinement to the point that the website fulfills its design strategy. The results also show that depending on how well the domain exploration is executed as well as how well the design strategy is defined will affect the resulting website and to what extent it fulfills its purpose, whether it’s is still a prototype or if it’s the end result.

    How Does CBM Function in the Real World?2016In: MFPT 2015 and ISA’s 61st International Instrumentation Symposium, At Dayton. Ohio, 2016Conference paper (Refereed)
    Abstract [en]

    Manufacturing organizations are under increasing pressure to meet customer and corporate demands by implementing improved maintenance initiatives to reduce costs, improve equipment availability, and protect against failure of critical equipment. Condition Based Maintenance (CBM) is widely accepted and used as a financially effective maintenance strategy which is used to anticipate equipment or component failure. Recent technological advances in component sensitivities, size reductions, and most importantly, cost has opened up an entirely new area of diagnostics. The economic benefit of CBM is achieved if the approach to maintenance is applied to the right equipment and through appropriate tools. In particular the degradation behavior of the equipment needs to be understood to correctly deploy a CBM approach and specific actions to specific equipment or components. Failure modes can be applied to support and optimise the decision making process. Using failure modes can be an efficient low-risk tool process for the prevention of problems, and is referred to as a deductive technique that consists of failure identification in each component. However, the literature is limited regarding the importance and the role of various failure models in different industrial sectors. Thus, if failure models are not known, understood and utilised correctly the use of CBM will not lead to financial benefits. The paper examines the relationship between the failure patterns observed in industrial maintenance practice and the corresponding impact on adoption and potential benefits of Condition-Based Maintenance (CBM). The paper will explain the need for accurate and up to date equipment information to support the correct maintenance approach. The paper suggests the importance of further supporting such investments by appropriately addressing the need to collect relevant data as a basis upon which to make the right decisions.

    Enhancing usability of e-commerce platforms by utilizing the usability factors: An investigation into user preferences.2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Availability of internet to a wide audiences has revolutionized how business is performed. Businesses now use e-commerce to trade products and services. The growth of e-commerce has been dramatically rapid among developed countries. Therefore, the adoption of e-commerce platforms is studied in these countries. Meanwhile less attentions has been given to developing countries. Developing countries can take advantage of lessons learned in the developed countries. One of the major success factors of e-commerce platforms in developed countries is improving the usability of e-commerce platform by considering user’s preferences. User preferences can be defined as feelings and attitudes of users for the interface and functional design of the ecommerce platform. This influences user’s decision and behavior. Considering the users preferences within an e-commerce platform enhances user’s satisfaction and increases user’s loyalty to the platform. To evaluate the user preferences a selection of usability factors are usually studied.

    Avicenna Research Institute (ARI) is currently considering the development of an e-commerce platform. For this ARI is investigating ways to consider users preferences in the design. This study aims to satisfy this goal. In this study previous research are analyzed, user’s preferences are identified, common used e-commerce platforms are investigated, and ARI’s perspective is included in the analysis. Using these information a set of recommendations on how to improve the usability of an e-commerce platform is given. For this task based approaches are used in form of participatory heuristic evaluation and observations. Interview is used to obtain ARI’s perspective on usability.

    The study has identified ten usability factors affecting the usability of the e-commerce platform based on user’s preferences. These include consistency, learnability, navigability, simplicity, readability, content relevance, supportability, interactivity, credibility, and telepresence. In addition a set of eighty evaluation criteria are presented to evaluate these factors. Using a qualitative approach, the study has analyzed all these factors in a multiple-case study. The analysis includes input from the users in form of observations, comments and questionnaire. This is combined with input from ARI in form of interviews. Finally the study concludes by providing a path for future research.

    User perspective of privacy and surveillance on social networks2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Social networks have integrated into people’s daily lives and they became a powerful medium for effective marketing and communication worldwide. Problem raise when governments and special agencies violate users’ information privacy under the pretext of protecting national security or something as, furthermore, when information became the source of income for social networks it became necessary to investigate users concerns about informational privacy on social platforms, if there are. The main purpose of the thesis is to understand what level of privacy awareness users on social networks have and how much relevant knowledge about surveillance on social networks they recognize. Moreover, the thesis aims to present users’ opinion about surveillance on Facebook and if they accept to be surveyed in certain scenarios. As results, the study has identified ambiguity in Facebook terms and data policy, while there has been clarity that Facebook applies massive surveillance in terms of data collection on all users on the network. 71% of the participants had concerns about their privacy on social networks, two-thirds of the participants didn’t read Facebook terms and 76% did believe that social networks sell users information for own benefits. The majority of the interview participants showed lack of knowledge about data collection on social networks, and didn’t know if governments do surveillance on social platforms or not. However, 37% of the survey participants claimed that they have nothing to hide and governments can look into their activities online, and almost similar percentage supported such an action. Further, most of the interview participants protect their informational privacy on social networks by having good privacy settings, controlling who have access to certain posts or managing friends list. However, 1/3 of the participants who had good privacy settings didn’t know all their friends on FB. Through personal observations on data analysis and literature review, I concluded the thesis with some suggestions of possible approaches to enhance information privacy, these recommendations present my own thoughts and weren’t derived in academic way rather personal notes during the thesis study.

    Kundorienterad lagerstyrning ur ett lean perspektiv: En fallstudie på ett medelstort tillverkningsföretag2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att skapa fördelar med lean kräver en gedigen hängivenhet i tillämpningen av lean filosofin. Studier har påvisat svårigheter hos medelstora tillverkningsföretag vid tillämpning av lean att skapa synergier mellan hantering av efterfrågan och lagerstyrning. En efterfrågehantering som skapat ojämnt flöde utav produktionsorder som lett till problematik med voluminösa och inkuranta lagernivåer.

    Med den problematiken som grund har en fallstudie utförts på ett medelstort tillverkningsföretag. Studien har syftat till att undersöka brister i efterfrågehantering, produktionsplanering samt lagerstyrning hos fallföretaget utifrån ett lean perspektiv samt föreslå förbättringsåtgärder. Studien har antagit en hermeneutisk utgångspunkt med en deduktiv ansats där teori först studerats för att sedermera samla in empiri för jämförelse.

    Resultatet av studien blev förslag på förbättringsmöjligheter för fallföretaget som då besvarat frågeställningarna hur ett tillverkningsföretag kan förbättra både sitt interna och externa lagerflöde. Studien har också lyft problematiken till ljuset och öppnat upp för diskussion hur ett företag med transparens och kommunikation kan förbättra varuflödet tillsammans med kunder.

    Personlig vårdhjälp: En kvalitativ studie kring information till cancerpatienter i komplexa vårdsituationer2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

     

    Much of cancer patients treated in Sweden feel that they receive inadequate information in connection with disease notification and treatment. Previous research has shown that a majority of these patients feel that they received too little information and they do not understand the information they received.

     

    The purpose of this project is to investigate whether information technology, in the form of an application,  can obtain personalized context-based quality information whenever the need arises. The application should also make it possible for the patient to be able to come in contact with the caregiver, via email, telephone or voice and video calls.

     

    To get a cancer diagnosis usually leads to a traumatic crisis which, in varying degrees, limit the ability to assimilate information. This, together with a very demanding treatment, both physically and mentally, places the patient in a very vulnerable situation. Being well-informed about the disease and treatment may help patients to more easily manage their situation and to improve mental well-being.

     

    In this work, pre-treated cancer patients were interviewed to determine what they feel is important for cancer patients to feel well informed, and the way in which an application could contribute to this. All the interviews showed that participants experienced that there was inadequate information in connection with their disease and treatment. The interviewees were aware that they had received information during their illness but their experience was that it was incomplete and performed at a time when they could not assimilate it.

     

    The interviews revealed proposals on the content of an imaginary application, all in one way or another related to information. The proposals were sorted under six headings which then became the inputs on the intended application's home page. A mockup was designed to demonstrate a proposal on the home page.

    Användarinvolvering i systemutvecklingsprojekt: En undersökning om hur användare påverkar innovativa lösningar i systemutvecklingsprojekt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study was intended to investigate the impact users have on system innovation in a system development project. As user involvement is done daily through (among others) user tests, it was interesting to investigate how user’s feedback and ideas affect innovation in a system development project. Companies today face great challenges of getting the user to believe in the change that is made in a system. What can be seen as a problem is that users aren’t always ready for the change that innovation entails. To investigate how users affect innovation in a system development projects, interviews have been conducted with people who have knowledge and experience of user involvement. The Unified Theory of Acceptance and Use of Technology model will be used to highlight the elements that affect users’ attitudes towards changes. The material that has been collected has been analyzed and discussed in order to answer the problem. Users affect system innovation by expressing negativity or skepticism against changes. The reason may be that users aren’t ready for the change that a company wants to implement. This can lead to the impediment of innovation in a system development project. An important aspect to include is the company’s domain expertise. If the company believes that the change should be implemented to be innovative, it’s important to communicate with the users and make them understand why the change occurs. An individual user can influence a system’s innovation if the company allows it, while a number of users can affect to a greater extent if they experience the same problem with an innovative change.

    Standardsystem och användbarhet: Hur ska man som utvecklare säkra att användbarhet uppnås i små SharePoint-projekt?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today, ICT (Information and Communication Technology) is often used to distribute and communicate information internal and external. One of the great tools for information management is the intranet. This research is focused on usability regarding small SharePoint-projects. Usability covers the factors: usefulness, customization and user acceptance. A small SharePoint-project (less than 300 working hours) has fewer resources available for focusing on usability.

    The purpose with this research is to examine developers’ attitudes regarding usability and how usability is best achieved in small projects where resources are limited. A quantitative method has been used to conduct a case study consisting of three developers in a consulting company. The interviews were semi-structured.

    The result from the research concludes that user acceptance is the key factor for an intranet to be perceived as useful by the users. Usefulness in a standard SharePoint solution is relatively defined and in place. Customization of a solution instead of using the built-in standards is often more costly and resource intensive. Developers should therefore focus on education, user involvement, communication and other factors that may increase acceptance among the end users.

    När äldre vuxna möter ny teknik: En kvalitativ undersökning kring digitalisering och digitalatjänster bland äldre vuxna2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The survey has been conducted about how older adults use digital services on the Internet,

    what their thoughts are about them and the problems that can arise during use. The

    purpose of the survey is to treat the qualitative data to see what factors affect older adults

    to use various digital services to operate in society. This purpose has arisen from the

    problem which older adults are the smallest but fastest growing user group to take

    advantage of digital opportunities, today's society more or less requires that you have

    some sort of digital knowledge to be able to benefit from its services. Based on the

    objective, we have formulated our research question "Older adults are the fastest growing

    group of digital users, but in total still the lowest represented user group. What contributes

    to the rapid rise and what can we learn from the users of today on how to develop digital

    services for this age group in the future?" We chose to write about this project because we

    think that the subject is relevant and interesting to explore. Since one can see the obvious

    problems regarding this in everyday life, we chose to more deeply explore the area to give

    us a broader view. We have used qualitative methods like observations and semistructured

    interviews, these have been applied from prior knowledge of how to perform

    these methods to enable a good data collection. We have also created our own modified

    model based on the Technology Acceptance Model (TAM) and the Unified Theory of

    Acceptance and Use of Technology (UTAUT) used to measure technology acceptance.

    The modified model is applied to the information we developed from them qualitative

    methods. The results from four informants indicate that there are critical factors that

    influence the use of digital services such as experience and needs, but these factors are

    individual and varies from person to person resulting in that there is not a single answer to

    the question but must be answered for each individual service.

    Light or Voice – make your choice!: Plocktekniker för tillverkningsföretag2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Companies constantly strive for the perfect order which enables them to satisfy and retain their customers. This is a difficult process that can be facilitated by using different picking technologies. In this study, a research of the picking technologies Pick-to-Light and Pick-to-Voice have been made to investigate when each technology is suited.In order to collect relevant information and data to be able to answer the question formulation, a qualitative study with interviews have been made. The purpose of this essay was to investigate Pick-to-Light and Pick-to-Voice to see when each technology is best suited and to see what the differences between the technologies are. With our essay we wanted to help manufacturing companies to make the right decisions when implementing a picking technology.The results showed that those picking technologies give companies a higher picking quality and an increased work efficiency since the order picking is faster to perform, and that picking errors are reduced. Through the interviews conducted, the result showed that Pick-to-Light and Pick-to-Voice are best suited at different types of areas. Pick-to-Light is optimal in small areas with high picking frequency while Pick-to-Voice is optimal in large areas with low picking frequency. Companies that are thinking of expanding in the future and use a picking technology on a much larger area, was recommended to implement Pick-to-Voice since this technology is more cost effective. Both of these technologies have multiple positive effects that are similar. Examples on these positive effects are that the operator has an overview of the items to be picked, the technologies are easy to learn and ergonomics are enhanced significantly when all paper handling is eliminated.Obviously, there are also differences between the techniques and also some disadvantages of each technique. The main differences are that the operator with Pick-to-Light can see which articles to be picked with the help of the luminous lights while the operator with Pick-to-Voice is voice guided to the items to be picked. Another major difference is that Pick-to-Voice is a wireless technology unlike Pick-to-Light and the ability to pick multiple orders at the same time is only possible with Pick-to-Voice. When it comes to maintenance costs, Pick-to-Light is more costly, both in time and money, since lights and cable must be replaced periodically. Likewise, an expanding with Pick-to-Light is more comprehensive since more cables and lamps must be purchased and installed. With Pick-to-Voice the only needed adjustment to make is in the system.Depending on the available conditions on the companies, the technologies are best suitable in different ways. Companies can use the technologies to secure the quality of the picking, reducing picking errors, and streamline the picking process. These technologies create the opportunity for companies to achieve the perfect order.

    Abstract [en]

    Internal dissemination of information is the primary resource for a functional organization. Transformation and dissemination of information is performed through communication where information progress between individuals and systems. Individuals knowledge are described as individuals that will interpret identical information variously, which results into information loss.

     

    A qualitative case study has been conducted with the perspective of exploring the interior horizontal information dissemination in order to create an understanding of how these informations perceived and applied in organizations.

    This study is focused on horizontal dissemination through SharePoint and e-mail and is expected to create understandning if the information that may result the work related effects.

     

    Since this study is restricted to the receivers and how they perceive and apply information, the empirical study represents that SharePoint is a valuable source of information and that it is perceived to be efficient compared with e-mail. Dissemination of information through email are used extensively and abundant of these materials are published daily at SharePoint, which results in loss of information.

    Transmission Model was primary used in order to get an understanding for how information transfers from a transmitter to a reciver. Sense Making Theory was applied as a supplement to the Transmission model to increase an perceptive of how the receiver perceives the transferred data. Information Systems Success Model based to obtain a perspective and an understanding for how a message is delivered by an electronic channel beyond and if the information was applied after it was received by the recipient.

    Tillit till automatiserade tester: En kvalitativ studie på en agil systemutvecklingsmiljö2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today, an increasing number of companies’ uses agile system development which means that the development work is done in short iterations. Short iterations means that there is much to be done in a short time both in development and testing. To keep up with the testing it is required to use automated testing. Automated tests are a type of automation that in itself is a problematic area because people fail to rely on automation. If people have a lack of trust in automated testing it will cause them to still use manual testing, which will make the value of automating tests fail.

    The purpose of this paper is to respond to how people ́s trust in automated testing is affected based on knowledge of automated testing, trust in the person creating automated tests and feedback from automated testing. A qualitative study and interviews have been conducted to answer the question. The survey has been conducted on a research company that delivers finance software and internet solutions to companies and accountancy firms.

    The result of the empirical survey shows that knowledge of automated testing, trust in the person who creates automated testing and feedback from the automated tests are aspects that affect people's trust in automated testing.

    Lack of knowledge affects people ́s trust in automated testing in a way that leads to that people either create an overtrust or mistrust to the automated tests. People that have knowledge of automated tests feels trust in the tests. To have trust in the person that creates automated tests affects people's trust in that way that people feel more trust in automated testing if they know who the person is, feel the confidence to the person and his or her knowledge. Feedback from automated testing affects people's trust when no-feedback is taking place. This leads to that they do not know which tests there is and what they do. This means that people do not trust them.

    Ett steg närmre användbarhet: Identifiering av de viktigaste designprinciperna för ett ärendehanteringssystem.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The world has become more digital and people have become more dependent on that technology always is accessible. Businesses are using technology to perform tasks more efficient and less costly. For information systems to facilitate the user, the systems must be useful. To achieve usability, design principles have been created. These principles are guidelines or directives to achieve a good design. When problems arise for a user, these users often must get in touch with knowledgeable IT-staff. The contact between user and IT-staff usually occurs via case management systems.

    The purpose of the study was to identify design principles that from the user's perspective are the most important for a case management system to achieve usability. The study was limited to examining Nielsen's ten heuristic design principles.

    The study was based on a deductive approach with a qualitative data collection method. Interviews were conducted on a case business to collect the views of users of a case management system. Width and variation was the method used for the selection of informants as it was of interest that the informants had different previous knowledge. The purpose of the empirical data was to identify important characteristics to achieve usability for a case management system. With this information, it was then possible to examine how well the design principles achieve these characteristics. The study also examined the users’ opinions about specific design principles, which also contributed to the results.

    The result of the study included four characteristics which the users felt should be met to achieve usability. Findability, navigability, information structure and simplicity are the characteristics users thought should be met to achieve usability. Furthermore, when design principles were evaluated, four principles emerged that users considered to be the most important, link between system and reality, flexibility and efficiency of usage, user control and freedom, compliance and standard, and to recognize themselves rather than remembering. These principles were those who were considered to answer the usability characteristics best.

    Information Inadequacy in Nuclear Power Plant Accidents2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study is to compare the cause of the, to date, three onlycommercial nuclear power plant accidents. These are very complex incidents,which have dire impact on society and the environment and therefore benefitfrom further investigation, if there lays a possibility of identifying factors thatcould prevent further accidents in the future. In order to investigate this theactions and decisions that lead up to each nuclear meltdown was identified andcompared.The investigation was based on a qualitative study on three cases of nuclearmeltdown accidents. They are based on text analysis of official reports anddocumentaries on the subject. The theoretical background for this study wasKajtazi’s (2011) work on Information Inadequacy. The study was limited to theevents leading up to the accidents and do not include activities afterwards.The study shows that each case had different underlying reasons. It alsoshows that we seem to have learned something from our previous mistakes, andacted on them accordingly. From the Fukushima Daiichi accident we canrecommend that organizations in charge should take early warnings seriouslyand act upon them as soon as they are presented.

    E-handelsplattformar som är anpassade för skalbarhet och ökad försäljning: En jämförelse mellan e-handelsplattformar.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this study 14 e-commerce platforms are compared based on their functionality. The functionality has been identified to increase sales and facilitate scalability. To rate the impact of the functions, e-tailors in the niche of clothing and accessories were asked to respond a questionnaire. To identify relevant functionality for both of the approaches, the researchers used literature. The functionality were used as a framework when comparing the 14 e-commerce platforms. This study indicates that all functions are not equal. Responsive design and multiple payment solutions are considered most critical and are directly linked to increased sales figures. For the e-retailers to achieve scalability, this study finds that purchasable add-ons and themes plays a big role. The e-commerce platforms were rated thanks to data collection and data analysis. Abantecart and Opencart both received high ratings regarding functionality and the ability to increase sales numbers and enable future expansions.

    Utvärdering av mobila gränssnitt för användare med nedsatt syn: Evaluation of mobile interfaces for visually impaired users2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study came about during ongoing discussions with a newly started company that plans to launch an application focused on fitness and health. The application must be accessible to a broad user group, this include users with some kind of disability. A large percentage of the population and a potentially large percentage of the company ́s prospective users have some kind of disability that can complicate use of the service, impaired vision is the most common kind of disability today. This study is based on the need to develop a concise and effective evaluation model intended to evaluate usability and to detect any possible problems that exist for users with visual impairments when using mobile services. Qualitative data has been collected from user testing and subsequent interviews. All test participants have a mild alternatively moderate visual impairment, the usability expert who carried out the heuristic evaluation is not visually impaired. The presented usability model has been tested and analyzed by posing as the basis for the heuristic evaluation, results found in this stage are then compared with results obtained from user testing in order to determine whether satisfactory results are met. The model shows satisfactory results based on obtained data, problems detected during the heuristic evaluation corresponds in a consistent manner with problems that emerged during user testing. The study indicates that there is a lack of specific and easy to use usability models for the evaluation of mobile services with a focus on visually impaired users. Such a model can preferably be used in order to increase usability and provide a more accessible service. Existing usability frameworks are often extensive and targeted at a broad user group. They can be supplemented with a time and cost efficient usability model directed at evaluating accessibility for a specific user group. The presented model is based on the principles of Universal Design which will hopefully contribute to a greater usability for the general user as well. In addition to improved usability a potentially great economic profit can be made by developing a more accessible service that can be used by more users. The study is based on proven methods and has support in existing theory which contributes to a higher quality assurance, however, the narrow scope of the study contributes to the necessity of further testing.
