    Towards Industry 4.0?: Digital Maturity of the Manufacturing Industry in a Swedish Region2019Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to assess the digital maturity of the manufacturing industry in a Swedish region. Data is collected using a survey conducted among the manufacturing industry in the region. Variables are based on prior research on digital maturity and Industry 4.0, and analyzed using descriptive and inferential statistical analysis. An initial finding was that several of the small organizations within the manufacturing industry does not have a basic digital presence in the form of a website, email or social media accounts, which calls for alternative approaches when assessing and developing digital maturity among these actors. The results from the survey reveal that perceived potential of digitalization and organizational enablers are ranked higher than actual operationalizations in the form of technology implementations and projects. Moreover, the digital maturity varies on variables such as organization size, location of customer base, and level of technological output. Organizations with a high degree of female employees perceive a higher digital maturity concerning some variables, which is an interesting subject for further studies. The overall conclusion is that a large part of the industrial sector in the region has not implemented anything that resemble the concept of Industry 4.0 in the literature.

    Ger certifiering enligt ISO 20000 kvalitetshöjande effekter?: Inom IT pågår ett paradigmskifte i form av att företagens egenproducerade IT‐miljöer håller på att bytas ut till förmån för köpta tjänster som populärt kallas "molntjänster". Hur vet jag som köpare att en leverantör med bra prissättning klarar av de kvalitativa krav som ställs på tillgänglighet, kvalitet och utveckling?2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Inom IT pågår ett paradigmskifte i form av att företagens egenproducerade IT‐miljöer håller på att bytas ut till förmån för köpta tjänster som populärt kallas "molntjänster", vilket förenklat kan översättas till elföretagens reklam "2 hål i väggen". Hur vet jag som köpare att en leverantör med bra prissättning klarar av de kvalitativa krav som ställs på tillgänglighet, kvalitet och utveckling?

    Det finns samtidigt en ny kvalitetsstandard, ISO/IEC 20000 som är inriktad på styrning av tjänsteleveranser inom IT, är standarden svaret på kundernas behov av mätning och uppföljning?

    Som leverantör ställer man sig frågan, är det värt mödan att certifiera sig enlig ISO20000?

    Arbetshypotesen är "Ger certifiering enligt ISO20000 kvalitetshöjande effekter?". Arbetet påvisar att ISO 20000 är väl uppbyggd enligt gällande kvalitetsteorier och att kvalitetscertifiering enligt ISO20000 ger goda förutsättningar för kvalitetshöjande effekt på IT­-företagens tjänsteleveranser.

    De anonyma 40-talsmöblerna: En uppsats om de osignerade 40-talsmöblerna2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats handlar om de okända 40-talsfåtöljerna och sofforna, de utan namn och signering. Min praktiska del i examensarbetet bestod av att renovera och klä om en

    40-talssoffa, och under arbetets gång av soffan hittades det aldrig någon lapp eller märkning angående möbelns ursprung, och det väckte mitt intresse och gav mig idén

    till den här uppsatsen. Uppsatsen har gått ut på att ta reda på vilka som gjorde dessa anonyma och okända möbler samt hur processen sedan gick till från stomme till färdig

    möbel.

    I genomförandet har jag använt mig utav en intervju, litteraturstudier och internet för

    att hitta information. Resultatet antyder att de som designade möblerna under 40-talet antingen var snickare

    på möbelfabrikerna eller företag så som Svenska slöjdföreningen.

    I slutet reflekterar jag över det resultat jag kommit fram och inte kommit fram till.

    Musikreception: Tillkommen informations påverkan på upplevelsen2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Målet i denna undersökning var att upptäcka och mäta om information kring okänd musik och artist kan ge upphov till en förändring i upplevelse av musiken. 21 deltagare fick vid ett lyssningstillfälle höra en låt med starka musikaliska influenser från mitten av 1900-talet. Dessa fick via en enkät besvara frågor kring dem själva samt hur de upplevde musiken. Efter de besvarat alla frågorna presenterades låten och artisten som är betydligt yngre än vad den musikaliska stilen antyder. Artisten född 1989 och musiken släppt 2015. Med denna nyvunna kunskap fick de lyssna på låten en gång till. De gavs även möjlighet att ändra sina svar angående upplevelsen av musiken. De visade sig att efter den andra lyssningen valde hälften av deltagarna att ändra sitt svar på en eller flera frågor. Den vanligaste förändringen gjordes i hur stort intresset att höra mer av musiken och artisten var. Och bland de som ändrade sitt svar gjordes den genomsnittligt största förändringen i hur väl deltagaren relaterade till låten. Detta kommer visa sig stå i relation till dels förförståelse, dels egna intressen och preferenser.

    Subjective analysis and objective characterization of adaptive bitrate videos2016In: Human Vision and Electronic Imaging 2016, HVEI 2016, The Society for Imaging Science and Technology, 2016, p. 55-63Conference paper (Refereed)
    Abstract [en]

    The HTTP Adaptive Streaming (HAS) technology allows video service providers to improve the network utilization and thereby increasing the end-users' Quality of Experience (QoE). This has made HAS a widely used approach for audiovisual delivery There are several previous studies aiming to identify the factors influencing on subjective QoE of adaptation events. However, adapting the video quality typically lasts m a time scale much longer than what current standardized subjective testing methods are designed for. thus making the full matrix design of the experiment on an event level hard to achieve. In this study, we investigated the overall subjective QoE of 6 minutes long video sequences containing different sequential adaptation events. This was compared to a dataset from our previous work performed to evaluate the individual adaptation events. We could then derive a relationship between the overall mean opinion score (MOS) and the MOS from shorter sequences. The aforementioned empirical dataset has proven to be very challenging in terms of video quality assessment test design, thus deriving a conclusive outcome about the influence of different parameters have been difficult. The second contribution of this study is considering how objective characterizations of adapted videos can improve the understanding of the subjective ratings.

    Quality of Experience of adaptive video streaming: Investigation in service parameters and subjective quality assessment methodology2015In: Signal processing. Image communication, ISSN 0923-5965, E-ISSN 1879-2677, Vol. 39, p. 432-443Article in journal (Refereed)
    Abstract [en]

    The usage of HTTP adaptive streaming (HAS) has become widely spread in multimedia services. Because it allows the service providers to improve the network resource utilization and user's Quality of Experience (QoE). Using this technology, the video playback interruption is reduced since the network and server status in addition to capability of user device, all are taken into account by HAS client to adapt the quality to the current condition. Adaptation can be done using different strategies. In order to provide optimal QoE, the perceptual impact of adaptation strategies from point of view of the user should be studied. However, the time-varying video quality due to the adaptation which usually takes place in a long interval introduces a new type of impairment making the subjective evaluation of adaptive streaming system challenging. The contribution of this paper is two-fold: first, it investigates the testing methodology to evaluate HAS QoE by comparing the subjective experimental outcomes obtained from ACR standardized method and a semi-continuous method developed to evaluate the long sequences. In addition, influence of using audiovisual stimuli to evaluate the video-related impairment is inquired. Second, impact of some of the adaptation technical factors including the quality switching amplitude and chunk size in combination with high range of commercial content type is investigated. The results of this study provide a good insight toward achieving appropriate testing method to evaluate HAS QoE, in addition to designing switching strategies with optimal visual quality.

    Förutsättningarna för solceller på Högskolan Väst: En förstudie om förutsättningarna för elproduktion från solceller ur ett miljömässigt och ekonomiskt perspektiv2015Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    This report highlights the conditions for Högskolan Väst to install a photovoltaic plant. Högskolan Väst is a school in Trollhättan, Västra Götaland. Högskolan Väst is planning to install a pilot plant with solar cells in 2015 as a part of their work for sustainable development, the plant is supposed to be used for educational purpose. The report describes solar energy in general and photovoltaic in particular, types of solar cells on the market, grid-connected systems, LCA of a solar cell, some energy sources are compared regarding energy payback-time and greenhouse gas (GHG) emissions, and installation solutions is presented.Sizing suggestions evaluate both roof and facade mounting. The expected electricity production is simulated in PVGIS, which use climate data from 1981-1990, and Solelekonomi 1.0, where the solar radiation data is provide from SMHI in 2007. In the economic calculations the payback-method is used and annuity’s calculations presented. A technical analysis presents various suppliers with differences and similarities regarding turnkey plants.The conclusion is that a budget of 300 000 SEK could be used to install photovoltaic on the roof of 15-20kWp (installed peak power) which is expected to produce 12 000-18 000kWh/year with a payoff-period of 19-22 years without subsidies. The mentioned budget could, as an alternative, be used to install photovoltaic as radiation protection at the facade of 10-15kWp with an expected production of 8 000-14 000kWh/year with a payoff-period of 24-28 years without subsidies. There are large variations in the assessment of the payoff-period due to variations in cost of a turnkey plant, the electricity price, the price of electricity certificates, subsidies, etc. Electricity production per installed Wp/m2 show small variations despite different mounting angels for the modules, but the production per Wp/m2 is lower for mounting on facade. The environmental analyses compare the energy payback-time from southern Europe with an average insolation of 1 700kWh/m2 and year, which can be compared with an insolation of 1 000 kWh / m2 and year for northern Europe. The crystalline silicon cells show higher values on average than hydropower, wind power and solar thermal energy but lower than amorphous silicon cells. The GHG emissions per unit of produced electricity through the lifecycle are at average lower for crystalline silicon cells compared to wind power, hydropower and solar thermal energy.

    Markerad plymå: Ett experimentellt studium2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens objekt är en av Carl Malmsten formgiven soffa med markerad plymå. Renoveringen av markerad plymå med traditionella metoder är tidskrävande och krånglig. Ofta väljer man enklare lösningar. Dessa förändrar soffan exteriört och formgivarens intentioner går därmed förlorade. I studien vill jag undersöka om det finns andra metoder som är möjliga att använde, vilka förenklar arbetet med att bygga en markerad plymå på ett sådant sätt att det är ekonomiskt rimligt samtidigt som soffans originalutseende behålls.

    I klädselarbetet av plymån prövas om fet finns praktisk möjlighet att förstärka illusionen av att plymån ligger lös genom användandet avtvå kedrar på kantbotten.

    Under det praktiska arbetet upptäcks också en tidsbesparande metod att fästa resårer genom att skruva fast dessa med fästen.

    En metod att bygga vulster med prefabricerade pappersvulster och sadeljord faller väl ut. Försöken att sy kedrar i plymån ger också önskat resultat. Studien visar att det är möjligt att renovera soffor med markerad plymå till originalutseende med rimlig arbetsinsats.

    Evaluation of quality of experience in interactive 3D visualization: methodology and results2012In: Proceedings of SPIE - The International Society for Optical Engineering, SPIE - International Society for Optical Engineering, 2012, p. Art. no. 82880O-Conference paper (Refereed)
    Abstract [en]

    Human factors are of high importance in 3D visualization, but subjective evaluation of 3D displays is not easy because of a high variability among users. This study aimed to evaluate and compare two different 3D visualization systems (a market stereoscopic display, and a state-of-the-art multi-view display) in terms of task performance and quality of experience (QoE), in the context of interactive visualization. An adapted methodology has been designed in order to focus on 3D differences and to reduce the influence of all other factors. 36 subjects took part in an experiment during which they were asked to solve different tasks in a synthetic 3D scene. After the experiment, they were asked to judge the quality of their experience, according to specific features. Results showed that scene understanding and precision was significantly better on the multi-view display. Concerning the quality of experience, visual comfort was judged significantly better on the multi-view display and visual fatigue was reported by 52% of the subjects on the stereoscopic display. This study has permitted to identify some factors influencing QoE such as prior experience and stereopsis threshold.

    Subjective evaluation of user experience in interactive 3D-visualization in a medical context2012In: Proceedings of the SPIE, vol 8318: Conference on Image Perception, Observer Performance, and Technology Assessment, San Diego, CA, USA, 4 - 9 February 2012, SPIE - International Society for Optical Engineering, 2012, p. Art. no. 831814-Conference paper (Refereed)
    Abstract [en]

    New display technologies enable the usage of 3D-visualization in a medical context. Even though user performance seems to be enhanced with respect to 2D thanks to the addition of recreated depth cues, human factors, and more particularly visual comfort and visual fatigue can still be a bridle to the widespread use of these systems. This study aimed at evaluating and comparing two different 3D visualization systems (a market stereoscopic display, and a state-of-the-art multi-view display) in terms of quality of experience (QoE), in the context of interactive medical visualization. An adapted methodology was designed in order to subjectively evaluate the experience of users. 14 medical doctors and 15 medical students took part in the experiment. After solving different tasks using the 3D reconstruction of a phantom object, they were asked to judge their quality of the experience, according to specific features. They were also asked to give their opinion about the influence of 3D-systems on their work conditions. Results suggest that medical doctors are opened to 3D-visualization techniques and are confident concerning their beneficial influence on their work. However, visual comfort and visual fatigue are still an issue of 3D-displays. Results obtained with the multi-view display suggest that the use of continuous horizontal parallax might be the future response to these current limitations.

    Minska risken för terrorbrott med hjälp av blockchain och geografiska informationssystem2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    How do companies, municipalities and authorities protect people from terroist attacks where large vehicles are involved? Considering to the last years terrorist attacks this is something that becomes increasingly relevant to consider. This study investigates how companies, municipalities and authorities solve these problems today, how much they know and apply blockchain and geofence and if there is a need to implement a geoblockchainsystem in the future to reduce the risk of these types of terrorist attacks. To find that out interviews have been conducted with participants all the way from truck manufacturers and carrier companies to municipalities, authorities and IT companies. The interview where constructed in a nonstandard way with the aim of developing more about what they themselves had for ideas about the subject. A survey with answer options was also sent out to obtain information from a larger number of participants. The result of the investigation indicates both the interest and the need of a geoblockchain system to reduce the risk of terrorist attacks of the specified kind (the investigation also indicates a general interest in the geoblockchain technology). The idea is to delineate areas using a geofence system and create a very secure information storage by connect the geofence system with blockchain. The blockchain system decentralizes the information, all transactions made must be approved by a several number of units to be performed, every transaction can always be tracked and nothing can ever be deleted or modified without making a new transaction. It was a very few of the participants that already use blockchain or geoblockchain, it was more common for informants to use geofencing, but that was also relatively unusual.

    Systemförvaltning med en agil metod: En fallstudie om Scrum inom systemförvaltning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At present, the area of agile management methods is a relatively unexplored area. The purpose of this study has been to investigate how well suited agile methods are for use in IT-maintenance. This has been done by collecting material on the subject, which acted as a base for a case study. In the study, the collected material from the investigated company, external companies and observations performed at the investigated company has been analyzed against existing theory in the field. Furthermore, conclusions have been drawn from information gathered during the course of the study. Based on this survey, it can be noted that in the activities that were investigated, an implemented agile method can add value to the maintenance operation. These added values present themselves in the form of a better and clearer structure, better communication and more effective working methods. One of the biggest challenges of agile agility in management has proved to be cross-functionality in the team. In this case as well as in other theoretical cases, the lack of cross functionality has been something identified. The theoretical cases show that the introduction of an agile method helps maintenance teams to become cross-functional. In the business investigated in this study, there were only indications stating that the business had started a transition to a cross-functional team. The fact that no definitive link between agile methods and transition to cross-functionality was identified in this case is considered to be due to the fact that the agile work was at an earlier stage. In conclusion, this study shows that agile methods are well-suited for use in maintenance, but some modifications to the agile approach need to be implemented.

    Healthy Performance in Small Enterprises: Studies of Organizational Determinants2003Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents explorative studies aimed at contributing to more knowledge about relations between organizational factors such as aspects of leadership, learning, psychosocial working environment and quality, and relations between these factors and outcomes related to organizational and health performance, in small enterprises. The main focus is not on particular relations in isolation, but on a whole set of factors and the relations between these. The background of the studies is that several public authorities and researchers have discussed that a good working environment and work organization could be related to increased workplace health and organizational performance. However, only a few of all proposals have been transformed into actions, although small enterprises are seen to have difficulties to carry on development processes due to limited resources and knowledge of such processes. The presented studies and analysis are two-level, using both organizational level data for fifty-two enterprises and individual data for the leaders and co-workers (1090 individuals). The empirical findings give support for probable links between healthy work organizational factors and outcomes related to organizational and health performance. Other findings are that several organizational factors are inter-related, and that it is possible to find grouping of enterprises on two general dimensions. This may give support to those working with a concept-driven or holistic change strategy by integrating several aspects, in small enterprises.

    Exact invertible hysteresis models based on play operators2004In: Physica. B, Condensed matter, ISSN 0921-4526, E-ISSN 1873-2135, Vol. 343, no 1-4, p. 148-152Article in journal (Refereed)
    Abstract [en]

    The present paper considers the definition of a class of hysteresis models, based on the superposition of play operators, which can be used to describe magnetic materials and superconductors. As a first step, the paper defines a class of non-local hysteresis models having an inverse operator in a closed form. That class specifies a Preisach model for which the exact inverse is defined. In this frame such a result is a generalization of the well-known result by Krejci. Moreover, a self-contained identification procedure is further addressed by using data measured either on magnetic materials and on superconductors.

    Abstract [en]

    The present study has examined the cultural and systematic quality work in social services.

    The main purpose was that through the application of cultural and force field analysis study how well prepared a unit in social services is to follow the intentions of systematic quality work in social services.

    The study was conducted based on the PDSA cycle as a variant of action research and was based on a case study in the Individual and family services in Hammaro municipality. The results were analyzed on the basis of a force field analysis, where with and counterweights were identified. My results show that overall there was a positive attitude towards systematic quality work, but that the culture did not suggest the same. In summary, the unit has poor conditions follow the intentions of systematic quality work. If they must be incorporated into the device's positive attitude persist, lead an active presence, employees involved and the culture is changing.

    The value of the study lies in the fact that in Sweden today there is an ongoing effort to implement or revise management system for systematic quality work in social services. The importance of culture of efficiency and successful quality work can not be elucidated. The study may provide inspiration for leaders and organizations, primarily in the social services, to reconcile systematic quality work and work culture.

    Further research should focus on the importance of leadership organizational culture, but there is also a lack of research that shows how improvement culture is created that extends across organizational boundaries and profession.

    In studies of 2D visual attention, eye-tracking data show a so-called “center-bias”, which means that fixations are biased towards the center of 2D still images. However, in stereoscopic visual attention, depth is another feature having great influence on guiding eye movements. Relatively little is known about the impact of depth. Several studies mentioned that people tend to look at the objects at certain depth planes. Therefore, it is reasonable to suppose the existence of a “depth-bias”. But studies proving or quantifying this depth-bias are still limited. We conducted a binocular eye-tracking experiment by showing synthetic stimuli on a stereoscopic display. Observers were required to do a free-viewing task through active shutter glasses. Gaze positions of both eyes were recorded for obtaining the depth of fixation. Stimuli were well designed in order to let the center-bias and depth-bias affect eye movements individually. Results showed that the number of fixations varied as a function of depth planes. There was also a relationship between the duration of fixation and the depth plane where the objects were located.

    Stereoscopic 3D video coding quality evaluation with 2D objective metrics2013In: Proceedings of SPIE - The International Society for Optical Engineering, 2013, p. Art. no. 86481L-Conference paper (Refereed)
    Abstract [en]

    The 3D video quality is of highest importance for the adoption of a new technology from a user's point of view. In this paper we evaluated the impact of coding artefacts on stereoscopic 3D video quality by making use of several existing full reference 2D objective metrics. We analyzed the performance of objective metrics by comparing to the results of subjective experiment. The results show that pixel based Visual Information Fidelity metrics fits subjective data the best. The 2D stereoscopic video quality seems to have dominant impact on the coding artefacts impaired stereoscopic videos.

    Examensarbeten som ett sätt att förbättra kompetensförsörjningen: Hur ser en framgångsrik process ut?2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this independent degree project was to develop new knowledge regarding how an organization can utilize thesis projects as a way of improving their competence maintenance. Two questions were raised to fulfil the project´s purpose, one dealing with potential role models´ current and desired practices, and the other dealing with what a process may look like based on knowledge of these.

    The method that was used to fulfil the purpose and answer the questions is a qualitative approach with abductive reasoning. Data which describes the current and desired practices of potential role models was collected through interviews and homepage investigations. This resulted in an abundant range of descriptions of recommended and desired practices, along with process maps describing the processes of potential role models. An organization, Västerås stad, was examined in order to form a process for successful thesis project handling in an actual organization. The process was illustrated in a process map, which was created by combining the recommended practices and ideas identified in previously mentioned interviews and homepage investigations, together with knowledge about the examined organization which was collected via interviews with personnel as well as documents given by the client at Västerås stad.

    The conclusion of this independent degree project was that a general successful process for thesis projects handling with the aim to improve competence maintenance, consists of the sub processes; create assignment, perform candidate selection, offer assignment, perform assignment, exploit knowledge from the assignment, investigate employment opportunities, reward the student and finally, evaluate and improve.

    Hantering av betalningsstopp i livsmedelsbutiker: En undersökning av hur hanteringen kan förbättras2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A well-functioning infrastructure is the foundation of a stable society, where payment systems are an important part. Grocery stores provide the general public with groceries and rely on customer consumption. Disruptions in the card payment system leads to consequences because 97% of all customers have access to card payment and is the payment method they prefer to use.  The aim of the survey is to find out about food stores' experience of disruptions in the payment system and how they wish a good management for this to look like. Next, a general crisis management model is developed to mitigate the consequences of a disruption in the payment system. A qualitative method is used to sample a result from each individual stores’ experiences and wishes.  Earlier research where decision analysis is used to handle disruptions in the payment system within the food industry has not been found. Through interviews and theories can a crisis management model for payment disruptions be developed, and examine the business continuity of food stores. The results of the survey shows that food stores today do not have any risk management to handle a break in the payment system or how a desirable management of it would look like. They have previously handled this by letting the customer pay with cash. A smaller store let a customer pay at another time. The general crisis management model has three phases: preliminary studies, management and evaluation. The preliminary studies involve that the store evaluates which payment methods they are capable of implementing. The management of a crisis takes place in three iterative steps; offer alternative payment methods, see how the crisis develops and finally remedy it. The evaluation step in the model is important because a positive outcome can not be guaranteed and therefore continued research is encouraged.

    Brister inom processbaserade informationsflöden: En undersökning av informationsbrister och hur dessa påverkar informationsflödet inom processer2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Industries consists of processes where hundreds of products are produced every day. This means that small flaws within the flow of the information or process can show up relatively fast. This creates an interesting question: how different forms of information flaws can affect processes. A few previous studies have been conducted regarding this area. This purpose of this study is to research the different forms of information flaws that can affect a flow of information between two processes. An information and process map has been created through a case study at Kubal. The researched process has been the flow of material between two processes. The conclusions of this research has been that the information flow between processes has to be tied together in every area, so that every relevant process owner is aware of the whole process. Failure to do so implies that the flow of information works sub-optimally. Another important point is to be consistent with what system is being used; lack of certain functions within a system generates additional systems that acts as complements to the main system, which implies that another problem arises within the flow of information

    The Subjective Perception of Risks by Individual Key Stakeholders Within SCRUM: A qualitative case study at an IT firm2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The lack of knowledge regarding the perception of risks in agile project management is evident in research. With this knowledge, this study sets out to address this issue and close the gap in knowledge regarding this issue by identifying the individual perception of risk by a project leader, SCRUM master, and two system developers, and comparing the individual appetite matrices to a unified appetite matrix created by a Delphi panel. A case study at an IT consulting firm, working with several projects in parallel, in Sweden is conducted. A risk register is used to collect the data, with the principle of assisting in creation of the risk appetite matrices. The result shows that the individual risk appetites differ significantly from the group’s unified risk appetite. The group showed itself far more risk aggressive than the individual appetite which was risk aversive in relation to the group’s appetite. The lack of RM practices is evident in smaller IT firms such as these, as there are no clear standardized approaches to the mapping or classification of risks; a far more informal approach is taken.

    Bankers resiliens vid större kriser: En studie av hur banker hanterar störningar i kortsystem2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today’s society is built upon different infrastructures; structured and integrated systems that are available generally. The consequences of an infrastructure that has stopped working may lead to detrimental implications for the dependent entity – critical infrastructure of said kind are called critical infrastructures. If a payment system would happen to cease to work, a bullwhip-like effect would occur within the financial infrastructure. To create resilience, i.e. the ability to counteract or rehabilitate such an event, is a methodology that may assist the society in handling crises such as these in a more efficient manner. The purpose of this study is to examine the banking sectors resilience in the context of disruptions within card payment systems. The study has been conducted with the help of interviews by different stakeholders working within the banking sector in Sweden. The collected data has been completely confidential. This study is of an exploratory nature, thus a qualitative research method has been applied. The interviews have been recorded and transcribed, and lastly analyzed. The conclusions drawn from the results and analysis has shown that the banks have knowledge of core principals of resilience. The banks resilience principals do differ from the principles conveyed in theoretical literature – while maintaining a unified view of said principles among themselves in the financial sector. The banks are prepared for short-term crises that may emerge, but they do not seem particularly prepared for long-term - more rare – crises.

    Vad är kunskapshantering?: En fallstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Knowledge management is a subject that is described in the literature as difficult-to-define, but important to an organization's competitiveness. Successful knowledge management is something that is also described as challenging with the subject's subjectivity. Critical success factors are used to gain an understanding of how knowledge management can be measured and implemented. The purpose of this study is to create an increased understanding of what knowledge management is all about. Through a literature search, two theses are formulated, which are then tested via a deductive approach. The first thesis states that knowledge management is seen as a process including different steps. The second thesis states that there exists a number of success factors for successfully implementing knowledge management. These are then tested against practice through semi-structured interviews in a case study. The result answers how knowledge management is perceived in practice, how success factors relate to each other and how these factors can be operationalized. The conclusion shows that informants perceive knowledge management differently, that success factors have a relation to each other and can be operationalized with a clear subject role.

    Camera Node for Conical Volumetric Surveillance2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Generally  cameras  are  used  for  area  based  surveillance,  but  with  advancement  in  technology, cameras  can  be  employed  for wide  area  space  surveillance  (volumetric space surveillance). The volumetric systems require a number of cameras in order to cover a large area. Single panoramic cameras  do  not  provide  required  functionality  for  wide  area  space  surveillance  and Pan-Tile-Zoom (PTZ) cameras do not either cover wide areas.   To  meet  this challenge,  we  propose  a  cost  effective smart volumetric  surveillance system  which utilizes smaller number of cameras in order to provide a coverage of 360 degree. A test case used for this system includes detection of birds in the wind farms. The proposed approach provides a solution  for recording/preventing collision  of  birds  with  wind turbine. To  realize  the  system, a model is developed with two camera nodes. This model provides a 360 degree conical volumetric space coverage. The  system is  utilizing  a  servo  motor  with  capability  of  changing  speed  and arduino  embedded  platform for  controlling  different  functionality. After  triggering  the  camera nodes from arduino, software perform the image analysis.  This  cost  effective  and  wide  area  surveillance  system  consumes at  least half lower  power as compared  to traditional  linear  systems with  eight  cameras. It  is  worth  noting  that  the system provides  conical  shaped  area coverage  of  200  square  meters  with  height ranging  from approximately 40 to 100 meters. The system would capture images in raw format in local storage and  the test  results  show  that  saving  images  with  PNG  format  requires a small  memory  size  as compared  to BMP  and TIFF.    Experiment  results  indicate  that  surveillance  system  can  be effectively employed for detecting birds in opening places.

    Abstract [en]

    Our society has undergone significant changes as new techniques came into our lives. Many areas of today’s society have digitalized in very short period and even healthcare sector is not exception. The County Council (Landstinget) provides an IT- system or e- service (MVK), which allows patients to book/ cancel appointments, renew prescriptions, order Patient Medical Records and much more. E- service was created just over 10 years ago. The service is aimed to all citizens, regardless of Computer- and Internet experience, gender and age. Since not all citizens are experienced in usage of IT, such system should be as easier and as user friendly as possible.

    This work is aimed to find weaknesses in MVK and find suggestions for improvement based on usability principles. Methods used in this work the combination of qualitative and quantitative methods.

    Therefore, I evaluated the service MVK, by implementing a number of usability tests.

    Test persons in this work were both men and women of different ages and different Computer- and Internet experiences. Test persons got a number of simple tasks, in which I felt we might find some faults.

    The most difficult of all was to find MVK on lg.se website. But it was not easy either to find Help on MVK. The best service of all available on MVK is to cancel/ reschedule the appointment and renew- prescription function.

    By using Time- on- task, I observed that inexperienced computer and internet users take longer time to perform certain tasks, compared with the expert and with other test takers. And that is right for them we should improve the system so that it would be easy for them to use it.

    In this work I could identify suggestions to improve the e- service, and could give suggestions to future research. Future research may be a reassessment of just a group of inexperienced users of different ages. We can also examine how the graphic design looks like and how it is to navigate on MVK. Or we can also re- evaluate e- service after the planned updates of MVK that would be carried out in a month, according to MVK developers.

    Taking a system view on customer value creation2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In Quality Management and Total Quality Management (TQM) customer focus and customer value creation is of importance and in organisations it is of high priority. Quality Management has had an internal focus when it comes to customer value creation but in the 21st century there is a need for an outward orientation and to go beyond the organisational borders. Also an increasing interest in social, societal and environmental issues can be seen, for instance by customers, organisations, quality awards and within the quality area. An area that considers these issues is the societal entrepreneurial sector.

     

    The purpose of this thesis has been to contribute to the knowledge and understanding about customer value creation from a system view. Additionally the purpose has been to contribute to the development of Quality Management. In order to fulfil the purpose, case studies have been performed. Cases within the societal entrepreneurial area have been studied and seven studies have been performed. Data have been collected through interviews, direct observations, participating observations and documents. All data have been collected empirically except in one study where a literature case study was used. The data were analysed through tools such as process mapping, attribute value mapping and rich picture process maps combined with analytical methods for case study research. The research journey started out from TQM and an internal perspective on customer value creation. As the studies went on, the system borders became wider as other areas important to customer value creation were identified: the customer value creating system went from an internal perspective to include an external perspective. 

     

    The findings contribute to earlier research findings and give a comprehensive and simplified picture of a complex phenomenon and an opportunity to understand customer value creation from a system view. This thesis provides an overall map of the customer value creating system. Additionally it contributes to the development of Quality Management by expanding the view on customer value creation to include both an internal and an external oriented perspective. It also contributes by suggesting a fifth step in the quality management movement ´System Quality Management´ that considers social, societal and environmental factors through continuous improvement before, during and after value creation for customers. Further it contributes with a developed view on customers and the concept of customer value creation.

     

    The overall map provided includes three areas.

    1. Growth and development of societal entrepreneurial initiatives. The result shows important components for the creation of societal value based on the growth and development of societal entrepreneurial initiatives. Included are the processes, input and output important for societal value creation from unidentified needs until societal value can be delivered, management process and support process fields.

    2.  Customer value creation in the customer sphere.  Customer value has been found to be created beyond the use or purchase of a product or service. Value has also been found to be created for those that are not in direct contact with an initiative or its product or service. Customer value has been found to spread into society like ripples in a complex system of value creation. And Value Ripple Logic has been developed to describe this phenomenon.

    3. Management role in customer value creation. The management’s role in value creation has been found to be of importance in the creation of customer value in an indirect way through interaction with the surroundings and the initiative.  Factors and behaviours have been found which are connected to the leaders and their essential management processes along with their input and output.

       

    The findings presented in this thesis have considerable potential for development. Further studies need to be done within the area concerning how customer value is created and to achieve an even more comprehensive picture of the customer value creating system and the suggested fifth step. The results presented in this thesis are a contribution to the knowledge and understanding about customer value creation from a system view and the development of the Quality Management.

    Management and customer value creation – learning from successful societal entrepreneurs2016In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to study management processes within successful Societal Entrepreneurship in order to further understand the role of management in customer value creation.

    Design/methodology/approach - management in three successful societal entrepreneurship initiatives that deliver societal value have been studied. Data have been collected through interviews, direct observation, participant observation and documentation. Management tasks, activities and behaviours have been identified and analysed to identify management processes and their input, output, main focus, drivers and relationship. The role of management in societal value creation has been analysed from a system view.

    Findings - The result presents essential management processes important for societal customer value creation, their input, output and main focus. Some management processes are inter-related and are sometimes part of another management process.  The management seem driven by ‘need’, ‘opportunity’, ‘interest’, and ‘demand’ when creating societal customer value. From a system perspective, management have an indirect role in societal customer value creation and are important for possibilities to create societal customer value. Both the initiative and the surroundings have been found to be of importance to the management’s scope for contributing to societal customer value creation.

    Originality/value – Studying successful societal entrepreneurial management and its role in customer value creation provides the possibility to understand and learn from management, its processes and role in societal customer value creation and how to successfully provide customer value to society and work with societal, environmental and sustainability issues.

    Value Ripple Logic - Customer Value Creation from a System ViewIn: Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this paper is to contribute to reflective practices and models to support the understanding and creation of customer value from a system view.

    Approach

    Case studies have been performed and data have been mainly collected through interviews and documents but also through archival records, direct observations and participating observations. Collected data was studied from a system view by making rich picture maps inspired by soft systems methodology (Jackson, 2003; Checkland and Scholes, 1990). Maps were made for each societal entrepreneurial initiative studied. The findings were then compared with the concept of Service Logic and a development out of the Service Logic concept resulted in the Value Ripple Logic (VRL).

    Findings

    The findings shows the Value Ripple Logic and an explanation of the concept. It includes a lexicon, a method to map and analyse customer value creation, an empirical example of customer value creation in a societal entrepreneurial initiative and a metaphor that describes customer value creation from a system view.

    Value

    VRL captures and illustrates customer value creation beyond a classical provider-customer relation and creates possibilities for understanding and analysing customer value creation from a system view. Which makes it possible to better understand the social, societal and environmental impact of an organization or initiative from a larger perspective.

    Optimeringsmodell för produktallokering: Baserat på processkartläggning och klassificering, en fallstudie2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Inventory management is considered to be an important activity that companies need to accomplish as improved methods directly can affect the final result. Product allocation within the warehouse is one of the vital parts of inventory management. This report is a case study where a warehouse of a manufacturing company is considered the case. The overall purpose is to investigate how a optimization model can help organizations with their inventory management, by first studying existing processes and based on that create the model to calculate optimal inventory allocation. The study has been conducted through a mixed method, divided into a quantitative and qualitative phase, as research claims that the key to the success of efficient inventory management is to match the layout of the warehouse case policy, stock layout and order types in order to customize the optimization model. In the first phase, a process mapping was conducted to build the optimization design. The second phase was based on mathematically describing the same problem setup, and then to model the problem with collected data. In the process-mapping phase, two differentiation criteria were identified as units sold packages and the unit production cost. The purpose of the classification was to identify which unique products that should be treated differently and receive assigned storage, which was an improvement opportunity found in the case description. A total of 93 products were placed on one of the 220 storage sites, with the aim of minimizing the mileage by truck. Comparison of target function values ​​between the optimal set-up model and the current set, demonstrated a theoretical saving of the number of driven meters of 35%. The study results have shown that mathematical modeling and linear programming can be used for inventory allocation problems to optimize product allocation, where the mathematical model is based on case-specific properties. The model's results are expected to facilitate a number of the problems noted in mapping inventory management processes.

    Effektivisering med hjälp av Lean: Hur kan principerna om Lean appliceras för att förbättra arbetsprocesserna i en organisation?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to research which Lean principles that could be incorporated in a small company. Lean is a more and more common expression that has become popular among companies that strive to find new ways of improvement and creating ways to compete on the market.  Lean as whole can be viewed as methods to increase the effectiveness of ones working processes through handling waste and increasing customer value. The company that was chosen for this study was Lundqvist Trävaru AB, a small family company located in the city of Piteå in northern parts of Sweden. Their main product is to create wall blocks that can be assembled into garages, cottages and storage units. The study was constructed in physical visits to the company while conducting participatory interviews and observations. A theory study was also conducted to find information important to carry on studying and analyzing the subject. The collected data was compiled into value stream maps and spaghetti diagrams covering the work in the factory of the company, then a MUDA-analysis was made to locate different types of waste and suggestions of improvements to eliminate this waste. To quantify the study a capacity process index (Cp) and specific capacity index (Cpk) was calculated and compared to the numbers in theory. The results showed that there are good possibilities to implements Lean principles into the company. The Cp and Cpk -index that was calculated gave an unclear result, this probably as a result of it being a difficult process to demonstrate this type of calculation. The conclusion of the study is that it has given a result and that there are possibilities to conduct further studies on the subject.
