    Små och medelstora företags utmaningar vid lean-implementering2017Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Följande examensarbete består av två delar, en litteraturstudie och en företagsstudie.Företagsstudien har genomförts hos Swedtrac Railservice AB. Företaget är verksamt inomjärnvägsindustrin där de har varit en typ av bemanningsföretag men nu håller på att ställa omsin verksamhet för att driva egna projekt. Företaget ingår i Knorr-Bremse koncernen som ären Europaledande tillverkare av bland annat bromsar till järnvägs och kommersiella fordon såsom bussars och lastbilar. I och med att företaget blev en del av Knorr-Bremse koncernen harde fått tillgång till det lean-baserade produktionssystemet ”Knorr-Bremse production system”(KPS) som de nu är i stånd att implementera i sin verksamhet.Syftet med examensarbetet åt företaget har varit att ta fram ett internutbildningsmaterial förlean-metoderna 5S och dagligstyrning. Som extra moment åt företaget genomfördes enskattning av den rådande implementeringsnivån av KPS samt en introduktionsworkshop omlean-konceptet och KPS för att skapa en gemensam grundförståelse. För att skatta KPS nivånsamlade studenten data genom intervjuer och observationer som sedan sammanställdes iskattningsmaterialet KPS Audit – Quick check. Det akademiska syftet har varit att besvaraföljande forskningsfrågor:

    • Vilka utmaningar ställs företag inför vid implementering av lean produktion?
    • Hur kan företag hantera utmaningar med implementering av lean produktion?

    För att identifiera utmaningarna och metoder för att hantera dessa genomfördes enlitteraturstudie där studenten sökte artiklar genom skolbibliotekets discovery-verktyg Primooch Google Scholar. Artiklar som ansågs relevanta för studien fokuserade på ämnen som;lean-implementering på SMF, företagsspecifika produktionssystem (XPS) och utmaningar vidlean-arbete.Litteraturstudien resulterade i identifieringen av fjorton utmaningar med koppling till fyrahuvudkategorier; ledning, ekonomi, kunskap och företagskultur. För att hantera de fjortonutmaningarna rekommenderades en cyklisk femstegsmodell för att kontinuerligt definiera ochhantera de fjorton utmaningarna allt eftersom lean-arbetet fortskrider. Den andra modellen vartill för den som ska leda ett lean-implementeringsprogram och går ut på att dela upp arbetet iimplementeringsfaser. Genom att göra detta underlättas resursfördelning och fokusering i deolika implementeringsmomenten.Det sista momentet i arbetet var att jämföra den data som inhämtats från företaget med deutmaningarna som identifierats genom litteraturstudien. Som resultat kunde studentenkonstatera att företagets huvudsakliga utmaningar är inom kategorierna företagskultur ochkunskapsnivån kring lean och KPS. Studentens rekommendation till företaget är att delta i ettlean program som ”Produktionslyftet” för att komma igång med arbete och att de investerartid och resurser för att utbilda medarbetarna i inom lean konceptet och KPS. Inom Knorr-Bremse koncernen finns mycket kunskap och erfarenhet som företaget har möjlighet att ta delav.

    Beyond being present: Learning oriented leadership in the daily work of middle managers2015Ingår i: Journal of Workplace Learning, ISSN 1366-5626, E-ISSN 1758-7859, Vol. 27, nr 6, s. 408-425Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose – This paper aims to contribute to the understanding of learning-oriented leadership as being integrated in managers’ daily work. The particular focus is on managers’ efforts to change how work is carried out through indirect acts of influence. In their daily work, managers influence the organisation’s learning conditions in ways that go beyond face-to-face interaction. Neither the influencer nor those influenced are necessarily aware that they are engaged in learning processes. Design/methodology/approach – The research was part of a larger case study. The data set comprised interviews with nine middle managers about ways of working during a period of organisational change. A learning-theoretical analysis model was used to categorise managerial acts of influence. The key concept concerned pedagogic interventions. Findings – Two qualitatively different routes for indirect influence were identified concerning social and organisational structures: one aligning, that narrows organisational members’ discretion, and one freeing, that widens discretion. Alignment is built on fixed views of objectives and on control of their interpretation. The freeing of structures is built on confidence in emerging competence and involvement of others. Research limitations/implications – The study was limited to managers’ descriptions in a specific context. An issue for future research is to see whether the identified categories of learning-oriented leadership are found in other organisations. Practical implications – The learning-oriented leadership categories cover a repertoire of acts of influence that create different learning conditions. These may be significant for the creation of a learning-conducive environment. Originality/value – Managerial work that creates conducive conditions for learning does not need to be a specific task. Learning-oriented elements are inherent in aspects of managerial work, and managers’ daily tasks can be understood as expressions of different kinds of pedagogic intervention.

    Making people’s work-integrated relations visible: Useable organisational images for managerial enabling of change2015Ingår i: International Yearbook of Adult Education – Theory, Methods, Empirical Findings / [ed] M. Schemmann, Köln: Böhlau, 2015, s. 89-110Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    This paper examines the potential contribution of organisation images where there is a need to understand and lead change. It is theoretically based on the dual assumption that leaders and co-workers learn when carrying out their work tasks, and that they act and make decisions according to their own conceptions. Intended change and development in organisations are as necessary as they are challenging. The paper aims to advance the idea of understanding organisational images as potential practical and pedagogical tools for informal change. Therefore, the paper discusses qualities of different types of organisation images in terms of their potential contribution to intended informal change, and how these images may provide support in the leading and organising of learning and development in organisations. In addition to the usual organisational chart, the visualisations ‘organisational circle’ and ‘task network’ are displayed and discussed and suggested to aid the asking of new questions, which may qualify the understanding of organisational change.

    Organizational Learning as an Analogy to Individual Learning? A Case of Augmented Interaction Intensity2015Ingår i: Vocations and Learning, ISSN 1874-785X, E-ISSN 1874-7868, Vol. 8, nr 1, s. 55-73Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper attempts to explore an analogy between individual and organizational learning within experiential learning theory (ELT). The focus is on both the possibility of identifying a learning subject that learns in action, and on the genesis process behind the learning of a suggested learning subject at organizational level. The exploration uses an empirical study of a global software communication organization. The research adopts a qualitative approach, with data from three middle-management layers of a research and development (R&D) unit with 5,000 employees. During the study, shifts of emphasis occurred between two organizational logics, which required work-integrated learning. Metaphorically speaking, the organization was portrayed as ‘teeming with interaction’, and a growing wave of change decisively altered both the thinking and work processes within the organization. The organizational learning process is theoretically understood as an ‘augmented intense interaction’ around a specific content. The subject that learns and upholds the outcome is suggested to be the teeming activity, comprehended as a living organism. In practice, the awareness of an organization as a body that teems with interaction has potential to offer new understanding about how to manage change.

    Managing offshoring of complex products: Strategy and capabilities2014Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Offshoring is a hot topic in the industrial and academic community over the last few years, evolving from a focus on manufacturing to product development and R&D. Offshoring refers to the process of sourcing and coordinating tasks across national borders and can include both in-house and outsourced activities performed by a supplier. There is a lot of research guiding the decision of what, where and how to offshore, but research on how to implement offshoring strategies is rare. The purpose of this dissertation is to contribute to the knowledge on how companies deal with offshoring in practice, relating to strategy, planning and routines. It discusses what type of capabilities that is needed to gain the benefits of offshoring implementations.

    The research builds on case studies from two multinational companies offshoring product development from Sweden to captive and offshore development centres in India and China through a series of interviews, review of business documentation and other types of active engagements over time.

    This research highlights how the development and implementation of offshoring can be better understood by focusing on the middle management in the organization and how they relate to the top management directives when implementing an offshoring strategy.  The thesis contributes to existing theory by explaining offshoring as a process, situated in a certain context and time. It defines key routines and capabilities needed to facilitate offshoring of complex product systems. Including context, timing and sequence when analysing offshoring help explain why some organizations fail to implement offshoring initiatives.

    The companies had an iterative learning process to deal with offshoring, and inclusion of all levels in an organization was highlighted as a key success factor for the implementation of offshoring. The results extend current understanding of offshoring of complex products to Asia and provide useful guidelines for managers on the key issues they need to consider.

    The middle management of offshoring: Understanding offshoring strategy implementation at a meso level2013Ingår i: Lecture Notes in Business Information Processing, 2013, s. 71-92Konferensbidrag (Refereegranskat)
    Abstract [en]

    A majority of the research on offshoring is positioned on a macro level, explaining firm level strategies for offshoring and the antecedents of offshoring decisions, but research on implementation of offshoring strategies is rare. The author suggest that the actual development and implementation of offshoring can be better understood by applying a meso level approach; the middle management in the organization and its relation to top management directives, when implementing an offshoring strategy. A multiple case study of two multinational company's offshoring product development to captive centers in India and China show how middle management facilitates the transfer process. By placing the study at a meso level and taking a strategy-as-practice perspective, the findings included: a) the iterative nature of the offshoring process, b) the lack of (communicated) strategies for offshoring and its consequences, and c) a set of routines connected to offshoring emerging at different levels in the company. © Springer-Verlag Berlin Heidelberg 2013.

    Produktutveckling miljöteknik: Framtagning av produkt som varnar vid förskämning av mjölk2017Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The aim of the thesis, industrial product design PPU304, is to develop a new product that will reduce food waste of dairy products in households. The main objective is that the product will be able to measure and signal when the milk has expired.The thesis is a start to find the solution to some of the food waste in households which is a major environmental issue in today's society. The goal is to develop a flexible expiration date that can reduce food wastage. With today's sensor technology bacterial levels can be calculated from the milk and that can increase the time a pack of milk can be used. The greater knowledge and awareness humanity have for environmental issues the better world we will live in. To understand the question, “what is it that makes the milk unfit for consumption?” A part of the work has gone into researching the technological aspect. In consumer ready milk there is different bacteria that will grow over time and eventually spoil the milk, how this process works varies depending on what or which bacteria manage to grow the most. Therefore, the most appropriate technique is to measure bacteria in the milk and identify at which level the milk passes its actual expiration date.The design of the product has been guided by two major factors, the predetermined dimensions of the circuit board and the adaptation to the size of the milk carton. The shape of the product is an oblong rear part with a spherical body at the front. The edges are rounded to give a pleasantand smooth feeling to the hand using the product.The thesis in industrial product design resulted in a final concept. The product analyses the amount of bacteria in the milk through sensors that measure bacterial metabolism. The data gets interpreted and displayed through the use of LEDs. To save energy the concept is equipped with a photo resistor that deactivates the LEDs when the fridge is closed and dark. The conclusion of the thesis, performed at Millcroft AB is at a conceptual level. To go from idea to product, is a process that takes a long time to complete and often involves many different moments. The timeframe during this study is considered too short to cover all parts of the product and therefore the boundaries set and the focus has been on constructing a design that fits the estimated technology as well as consumer needs. Some suggestions are that more research in the technical aspect of the product should be concluded. Further testing of dairy sustainability should be conducted on a larger scale and further development of the technology to send data.

    Development of the web application My Stress Control—Integrating theories and existing evidence2018Ingår i: Cogent Psychology, Vol. 5, nr 1, s. 1-19Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To describe the systematic development of an evidence-based, tailored, interactive web application for self-management of work-related stress, and to test usability issues regarding how to proceed through the programme. Methods: Evidence from the fields of stress management, behaviour change and web-based interventions was the foundation for the theoretical framework and content. The next step was the development process of the web application and validation among experts and one possible end user. Last, a usability test with 14 possible end users was conducted. Results: The web-application, My Stress Control (MSC), was built on a solid theoretical framework. It consists of 12 modules including: introduction, psychoeducation, ambivalence, stress management strategies, lifestyle change, and maintenance. Self-monitoring, goal-setting, re-evaluating goals, feedback, and prompting formulation of intention to change are central techniques supporting behaviour change. The usability test revealed difficulties in understanding how to proceed through the programme. Conclusion: The development contributes to filling a gap in the literature regarding development of complex web-based interventions. MSC is dissimilar to existing programs in the field, considering the tailoring and multi-tracked opportunities. Although developed from the evidence in multiple fields, the web application would benefit from further development to support users in reaching the end module.

    Evaluation of a Web-Based Stress Management Application: A Feasibility Study2018Ingår i: Journal of Technology in Behavioral Science, ISSN 2366-5963, Vol. 3, nr 3, s. 150-160Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the current study was to investigate the feasibility of a Web-based program that promotes behavior change for stress-related problems in terms of the program’s acceptability, practicability, and any possible effects. In addition, the aim was also to study how appropriate and realistic the study’s process and resource management would be for conducting a randomized controlled trial. A convenience sample consisting of 14 individuals was recruited from a university in Sweden. The participants had access to the program for a duration of 9 weeks. Questionnaires were answered before accessing, during use of, and after completing the program. Both qualitative and quantitative data were collected and analyzed. The program was considered acceptable and practically feasible, though small adjustments have to be made. The program was considered time-consuming, extensive, and in need of some clarifications. Regarding process and resource management, the study participants required minimum support. It was difficult to identify the time point when to send out the process measures because the participants worked at their own pace. Also, one of the process measurements, the motivation to change, remained stable. With some adjustments to the instructions to the study participants and minor changes in the program, the intervention and study’s procedure were considered as feasible and can be carried out in a randomized controlled trial.

    User experiences from a web-based, self-management programme: struggling with what I need when stress management is about me2019Ingår i: European Journal of Physiotherapy, ISSN 2167-9169, E-ISSN 2167-9177, s. 39-48Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To explore users’ experiences of a tailored, interactive web application that supports behaviour change in stress management and to identify if and in that case what in the web-based programme that needed further development or adjustment to be feasible in a randomised controlled trial.

    Method: The design of this study was explorative with a qualitative approach. Nine individuals were recruited among the staff at a university. Semi-structured individual interviews were conducted and analysed using qualitative content analysis, after the participants had completed the web-based stress management programme.

    Results: One theme was identified, Struggling with what I need when stress management is about me, describing the paradox in having a programme that is perceived as supporting stress management while also being perceived as extensive and time consuming. The theme was divided in two categories: Defining the needs, where the users expressed what they needed from the programme and their everyday environment, to be able to use the programme, and It is about me, where the programme was described as helping the users understand their own stress.

    Conclusion: The participants expressed acceptance of using a web-based programme for stress related problems. The perceived extensiveness of the programme must be considered in further development.

    Beräkning av hissgejder2015Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    En central komponent i ett hissystem är gejder. Dessa fungerar som ledskenor och styr hissen i dess färdriktning. De ser till att hissen hålls på plats och tar därför upp alla de krafter som av olika anledningar genereras av obalans i hissen. Om dessa krafter blir för stora uppkommer skador som kan leda till olyckor och det är därför viktigt att dimensionera gejderna rätt.

    Företaget Kone AB har genom tiderna utvecklat flera olika beräkningsverktyg för att teoretiskt bestämma hur stora påfrestningar en specifik hiss kan utgöra på dess gejder. Dessa verktyg har framförallt fokuserat på installation av nya hissar och dagens förutsättningar. Med tiden har föreskrifter, normer och standarder förändrats. Nya gränsvärden och regler har medfört att nya verktyg utvecklats för att kunna anpassas efter detta. Beroende på vilken del av en hiss som moderniseras, gäller fortfarande de föreskrifter och riktvärden som var gällande då hissen uppfördes. I samband med nyutvecklingar av beräkningsverktyg har man släppt supporten av gamla versioner och många av de äldre programmen har idag kompabilitetsproblem med dagens plattformar. Man har heller inte behållit någon möjlighet till att räkna efter gamla regler och riktvärden. Detta har medfört glapp i tillgängligheten av beräkningsverktyg anpassade för moderniseringar och har lett till att mycket tid har spenderats åt att genomföra dessa beräkningar med papper och penna.

    Arbetet har genererat ett nytt beräkningsverktyg skapat i Microsoft Excel och Visual Basic for Applications med fokus på att lämna så mycket som möjligt konfigurerbart. På detta sätt kan man anpassa alla nödvändiga parametrar och riktvärden efter de föreskrifter som gällde då hissen var uppförd. Plattformen valdes då det finns gott om allmän kännedom om denna inom företaget för att underlätta framtida vidareutveckling och inte få problem med otillgänglig källkod.

    Ett sidospår ledde in på en utredning gällande materialegenskaper för gejder tillverkade på tidigt 1900-tal. Detta ledde till för få resultat för att kunna dra några slutsatser och någon gemensam standard kunde inte finnas.

    För framtida vidareutveckling av verktyget rekommenderas grafiska illustrationer av resultatdelen samt implementation av fler områden som kan automatiseras inom avdelningen.

    Factors influencing control charts usage of operational measures2017Ingår i: Measuring Business Excellence, ISSN 1368-3047, E-ISSN 1758-8057, Vol. 21, nr 3, s. 225-238Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: The purpose of this paper is to identify factors influencing implementation of control charts on key performance indicators (KPIs). Design/methodology/approach: Factors driving organizational change described in literature are analyzed inspired by the affinity-interrelationship method. A holistic multiple-case design is used to conduct six workshops to affect the usage of control charts on KPIs at a global company in the automotive industry. The theoretical factors are compared with the result from the case study. Findings: The important factors for implementation success differ to some extent between the theoretical and empirical studies. High-level commitment and a clear definition of the goal of change could be most important when creating a motivation for change. Thereafter, having a dedicated change agent, choosing an important KPI and being able to describe the gain in financial terms becomes more important. Practical implications: By using control charts on KPIs, the organization in the case study has become more proactive, addressing the right issues upstream in the process, in the right way, cross-functionally. Originality/value: Factors affecting the implementation of already available solutions in the industry are highlighted. This potentially provides a basis for improved decision making, which has a significant value.

    Exploring quality challenges and the validity of excellence models2016Ingår i: International Journal of Operations & Production Management, ISSN 0144-3577, E-ISSN 1758-6593, Vol. 36, nr 10, s. 1201-1221Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: The purpose of this paper is to identify and explore important quality-related challenges facing organizations, and investigate how current excellence models incorporate these challenges. Design/methodology/approach: The paper is based on a Delphi study of Swedish organizations. Forty-nine challenges were generated and ranked according to importance and the ten top-ranked challenges were compared to the principles of four excellence models. Findings: The excellence models still seem to be relevant since their content matches many of the identified challenges. The Malcolm Baldrige National Quality Award and the Swedish Institute for Quality models were found to have the most comprehensive coverage, while the International Organization for Standardization model had limited coverage. Research limitations/implications: Three areas for further research were identified: first, how quality management (QM) can evolve in different contexts that have varying needs in terms of adaptive and explorative capabilities; second, the interfaces of QM and sustainability, and ways to understand how customers and stakeholders can be active contributors to improvements; and third, the roles of the owners and board of directors regarding QM, and how to organize and distribute responsibilities of the QM work. Practical implications: There are three important challenges that future revisions of excellence models could address: first, making QM a strategic issue for company owners; second, involving customers in the improvement activities; and third, developing processes that are robust yet still easily adaptable. Originality/value: The Delphi study identified upcoming challenges in the QM area based on input from 188 quality professionals.

    Testrigg för Tätning av Marin Transmission2019Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Projektet syftar till att framställa ett konceptförslag på en principiell konstruktion av en testutrustning åt Volvo Penta, där undersökning av deras tätningar skall kunna utföras. Problemet i dagsläget är att det är svårt att få ut konsistenta provresultat vid tester ute i havet eftersom testmiljön aldrig är identisk varje gång.

    Inledningsvis granskades faktorer som kan påverka testmiljön, där en lista över de som vi ansåg ha störst effekt skapades. Därutöver diskuterades vad som krävdes för att erhålla en fungerande testutrustning. En utförlig informationsinsamling genomfördes för att grundlägga arbetet med teori som krävdes för att sammanställa en konstruktion. Material jämfördes och hållfasthetssimuleringar i form av FEA, undersöktes. Resultatet blev en teoretisk testrigg som uppfyller kravspecifikationen, funktionsanalysen, och presenterades i 3D modellerade bilder genom CAD.

    Live-action Communication Design: A Technical How-To Video Case Study2019Ingår i: Technical Communication Quarterly, ISSN 1057-2252, Vol. 28, nr 1, s. 69-91Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This case study is based on a research through design project (RTD) that focuses on a technical communication video of the live-action format. It investigates the usability and design-implications of a live-action how-to video, by means of analyzing user-centered data such as YouTube analytics data, usability, and comprehension assessments. In the study, four key live-action video affordances are identified: verifiability, comparability, recordability, and visibility. The identification of these affordances when related to the users’ assessments resulted in several design implementations that would warrant sought-for communication efficacies. Findings show that some assumed efficacies appear to be mitigated by the complexity and the density of the video information. One implication of this is that the implementation of conventional video editing techniques and the addition of on-screen text that serve to make content briefer and more concise into instructional live-action videos requires the technical communicator’s careful consideration.

    Syncretistic images: iPhone fiction filmmaking and its cognitive ramifications2015Ingår i: Digital Creativity, ISSN 1462-6268, E-ISSN 1744-3806, Vol. 26, nr 2, s. 138-153Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Abstract: This article will address the question of how fiction films are individuated in terms of image quality on the grounds of the recording technology used. As new cost-effective digital recording technologies are introduced to the marketplace, this becomes a salient issue to understand for producers and production teams. In order to define cameras’ image quality capacities, three almost identical short fiction film sequences were tested on a young audience in a comparative blind test. Surprisingly, the result unambiguously showed that most viewers preferred the film recorded on an iPhone. Based on Barbara Maria Stafford's theoretical framework on the cognitive work of images and theories that concern ecological moving image theory, the analysis of this article aims to explain the reception study's result by illuminating the sublime and ambiguous figure–ground constellation of the iPhone video and its cognitive ramifications.

    Media instructions and visual behavior: An eye-tracking study investigating visual literacy capacities and assembly efficiency.2014Ingår i: Analyzing Cognitive Processes during Design: Proceedings of the HBiD 2014, 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    This pilot study aims at illuminating human visual behavior in the interaction with pictorial instructions. The study is a multi disciplinary effort and is informed by the connection between gaze and attention as well as certain aspects of the Visual Literacy field and reveals a few basic visual behavior tendencies related to certain specific pictorial instruction types. By doing so, it is also an evaluation of the usefulness of a methodological framework consisting of six measures.The analysis of this paper is primarily based on eye-tracking data. In addition, an observed assembly that generated video and sound recordings is also part of the method. In the study 12 Film/TV- production students (out of which there is complete data from 9 informants) interacted with three types of types of visual instructions of the same assembled object, a solar powered toy.

    How gaze time on screen impacts the efficacy of visual instructions2018Ingår i: Heliyon, ISSN 2405-8440, Vol. 4, nr 6, artikel-id e00660Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article explores whether GTS (gaze time on screen) can be useful as an engagement measure in the screen mediated learning context. Research that exemplifies ways of measuring engagement in the on-line education context usually does not address engagement metrics and engagement evaluation methods that are unique to the diverse contemporary instructional media landscape. Nevertheless, unambiguous construct definitions of engagement and standardized engagement evaluation methods are needed to leverage instructional media's efficacy. By analyzing the results from a mixed methods eye-tracking study of fifty-seven participants evaluating their visual and assembly performance levels in relation to three visual, procedural instructions that are versions of the same procedural instruction, we found that the mean GTS-values in each group were rather similar. However, the original GTS-values outputted from the ET-computer were not entirely correct and needed to be manually checked and cross validated. Thus, GTS appears not to be a reliable, universally applicable automatic engagement measure in screen-based instructional efforts. Still, we could establish that the overall performance of learners was somewhat negatively impacted by lower than mean GTS-scores, when checking the performance levels of the entire group (N = 57). When checking the stimuli groups individually (N = 17, 20, 20), the structural diagram group's assembly time durations were positively influenced by higher than mean GTS-scores.

    Abstract [en]

    A growing population of elderly people with an extensive knowledge of ICT is to be expected - a generation that has several decades of daily experience from using computers, cell phones and other devices at work situations and in their spare time. Today the discussion of elderly people and technology is dominated by the perception that the elderly are comparatively inexperienced with regard to digital technology. The challenge for the future is, however, to overcome the gradual loss of the senses with the help of technical devices that fulfill the needs of older technologically mature users.

    The perception of aging and use of robots2018Ingår i: Lecture Notes in Computer Science, Volume 10926, 2018, s. 30-39Konferensbidrag (Refereegranskat)
    Abstract [en]

    The implications of robots’ design for their acceptance in nursing settings, particularly for elderly people and those involved in their care, have not been thoroughly considered from an information design perspective. This research gap is addressed here, as such a perspective enables consideration of several important socio-cultural aspects of robots, including potentially significant elements of visual culture. Since all these aspects influence views of robots as aids for elderly people, there is a need to understand how robots’ design (in terms of appearance) and perceptions of aging influence intended elderly users, their relatives, caregivers and decision-makers. Robots materialize digital technology, both metaphorically and literally. AI and embedded systems enable robots to act, but the shape and materials selected to make them influence our interactions with them. Thus, as shown in this paper, application of an information design perspective can provide deeper insights about the influences of current and historical culture and media on both the perceptions and experiences of aging, and relations of these perceptions and experiences to the acceptance (or lack of acceptance) of robots as tools for nursing old people.

    Improving Quality in Higher Education by using Living Lab Methods2019Ingår i: Proceedings of the OpenLivingLab Days Conference: Co-creating Innovation: Scaling-up from Local to Global, 2019, s. 394-407Konferensbidrag (Refereegranskat)
    Abstract [en]

    This conceptual paper presents a Living Lab model of how university, societyand organisation may strengthen the co-creation capacity on regional and international level to improve quality in higher education. Our conclusions are that successful co-creation between universities and society/organizations is built on mutual contribution, knowledge sharing as well as engagement from all involved. Here, living lab methods can help improve quality. Further, from a university perspective, a challenge is to keep the engagement in the project from all involved, and to assure an equal status between stakeholders. This calls fora skill in how to conduct project in co-creation with several partners. A skill that has to be taught to students as well as to teachers and researchers.

    Teachers' Role in Blended Learning: The Emperor's new Clothes?2017Ingår i: PROCEEDINGS OF THE 16TH EUROPEAN CONFERENCE ON E-LEARNING (ECEL 2017) / [ed] Mesquita, A Peres, P, ACAD CONFERENCES LTD , 2017, s. 163-168Konferensbidrag (Refereegranskat)
    Abstract [en]

    From a theoretical perspective, this paper problematizes the future role of teachers in higher education, especially in the Swedish context, placing opportunities and raised challenges by blended learning in a historical context of distance education. Distance education was introduced in the late 19th century and has been offered by two main actors in Sweden: the correspondence school Hermods and universities. It has been viewed as a part of life-long learning, a concept introduced in the 1960s. The correspondence schools offered elementary education courses, and in-service training for various professions, while universities largely focused on higher education but also provided education or training commissioned by other organizations. Recently, the teaching requirements and role of the teacher in distance education have changed dramatically, from formulating exercises and commenting on students' work to giving videotaped lectures in English for an open audience. However, there is still a lack of appropriate guidance for teachers on effective pedagogical practice in the new settings. Specifically, there is an increasing need to support teachers in designing and creating effective videotaped lectures that are accessible for a dispersed audience. The TED talks seem to provide a role model for performance as a lecturer, but the average teacher hardly has time to both prepare regular face-to-face lectures and distance lectures, e.g. extensively rehearse before recording. The paper discusses how the challenges of future roles of teachers can be met when lecturing in front of a camera.

    Abstract [en]

    Purpose – Strategic changes in an organization will face challenges not only related to the changes as suchbut also with regard to how the vision of the future is interpreted and understood by the organization.Visual management is a field of research that could contribute to change management research as a meansto facilitate management of the dynamics in a change process and to facilitate the process ofcommunication. The purpose of this paper is to problematize episodic change processes with regard tocommunication and to contribute with a proposed model on how to facilitate dynamic strategic changemanagement using visual management.Design/methodology/approach – The paper uses an interdisciplinary approach by linking changemanagement literature to visual communication to be used for visual management.Findings – A proposed model presents how a dynamic episodic change process can be managed in terms ofvisual management, potential pitfalls to avoid, and what ambidextrous capabilities are needed throughout thecomplete episodic change.Research limitations/implications – The proposed model is still yet theoretical, based on a literaturereview of dynamic change management and visual communication. Future research will validate the model inpractice to confirm its robustness.Practical implications – An implementation of visual management in Kotter’s (1995) eight steps on how tostrategically manage change in combination with theories on ambidexterity and episodic change is suggested.Originality/value – The paper contributes to how visual management can support change management bycombining visual communication and change management.Keywords Quality management, Change management, Strategic planning, Operations management,Visual management, Visual

    Showing Action in Pictures2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    One challenge for the global market is to overcome communication problems of different kinds. The largest communication problem is language, people speak different languages and have limited knowledge in other languages. This problem is central in manuals and instructions for assembly and installations. One hopeful solution is that pictures can replace verbal instructions. In this paper we will discuss how illustrations in flat perspective can be useful for showing action in drawings.

    Using VR to improve the design of assembly tasks and increase task efficiency2018Ingår i: Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018, The Design Society , 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we discuss how theories of vision, touch, sound, and learning behavior can form a basis for the development of a testbed through which real-life task performance can be compared with task performance in a Virtual Reality (VR) environment. By taking a multisensory approach, it will be possible to simulate the functionalities of a real training setting in a VR environment. Approaching this problem from a theoretical perspective, we will view it from a new angle and discuss whether we can enhance and nuance feedback in the virtual experience through the use of ambient media like sound, scent, heat, and wind. Sound may hold a great potential here. For visual perception, it is not only crucial that we can see relationships but that we are also able to search for patterns that we recognize. If an object is taken outside its context, its meaning can easily shift. To see is to search for patterns, but vision is also dependent on our experience of other senses. We can imagine how a given surface might feel by looking at a representation of the object, and this is because of previous tactile experiences with similar objects. From a technical perspective, integrating sound in a virtual environment is a straightforward process. Research shows that the process of learning a series of physical actions can be enhanced when it occurs in parallel with verbal or written information. In the literature, this phenomenon is described in terms of enactment or subject-performed tasks. Based on theories regarding vision, touch, sound and learning behavior, we suggest the design of a testbed that can be used in a pilot study aimed at increasing knowledge on how VR and AR can support learning in an assembly or installation context in order to produce guidelines for such an environment.

    Approaching the Reduction of Uncertainty in Production System Design through Discrete-Event Simulation2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    The presence of uncertainties associated to the introduction of novelty and significant change challenge manufacturing competitiveness. Addressing this issue, the purpose of this qualitative case study is to examine the uncertainties reduced by Discrete Event Simulation (DES) use during the design of a production system when significant changes are introduced at a manufacturing company. The results of this paper, based on empirical findings from a Swedish manufacturing company, reveal the presence of eight different uncertainties affecting the design of a production system including state, technical, environmental, systemic, temporal, structural, epistemic, and definitional. Empirical results also show how DES contributed to reducing technical, structural, epistemic, and definitional uncertainties. This paper contributes to existing knowledge by proposing a model that aids decision makers anticipate the type of uncertainty faced and the suitability of DES use as an uncertainty reducing activity during significant change introduction in the design of a production system.

    Production control mechanisms in a convergent production line2013Ingår i: Hamburg International Conference of Logistics 2013, Lohmar , 2013, s. 319-332Konferensbidrag (Refereegranskat)
    Abstract [en]

    One of the critical elements that managers face in manufacturing companies is to find an appropriate Production Control Mechanism (PCM) for their shop floor. There are many different PCMs and each of them has different performance depending on the situation. A convergent production line is a situation that rarely has been studied from this perspective. This study compares three kind of PCM that are identified as suitable for such a complex production line: POLCA, CONWIP and m-CONWIP. Extendsim simulation software was employed for discrete event simulation in order to compare performance of the considered PCMs in a convergent production line producing one type of product. The results indicate that the studied PCMs show distinct different performance in the various configurations of the convergent production line. The simulation shows (a bit surprisingly) that POLCA has the best performance in the considered situation and m-CONWIP has the worst performance. However, in an even more complex situation with more product types, the performance of POLCA would be under question. The study complements previous studies on PCM applicability and configuration, and has a strong industrial implication for the increased emphasis on decision support for operations management in a resource efficient production setting.

    Attribute Control Chart Development by Evidential Reasoning2014Ingår i: Proceedings of The 3rd international workshop and congress on eMaintenance, 2014, s. 37-40Konferensbidrag (Refereegranskat)
    Abstract [en]

    Attributes charts are commonly used in monitoring quality characteristics of the proportion type and these charts assume that the monitored characteristics are binomially distributed. Classical control charts need to certain and precise data. However, in practice, quality experts express their opinion in imprecise form, which in turn, add more uncertainty and ambiguity. It is essential to properly represent and interpret uncertain information to evaluate product items. In this paper, the evidential reasoning (ER) based approach has been developed for supporting this uncertainty. So the belief multinomial p-control chart is introduced for monitoring the production process in the uncertainty condition, using evidence theory and the belief structure. A numerical example showing production process evaluation is examined by using the ER approach. The results show the proposed approach, is effective not only for reducing production defective but also for increasing the certainty in interpreting of quality variables (data).

    Challenges with Supplier Involvement in Product Development: A Supplier’s Perspective2019Ingår i: Proceedings of the International Conference on Engineering Design, ISSN 2220-4334, E-ISSN 2220-4342, Vol. 1, nr 1, s. 2179-2188Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Studies of supplier involvement in product development have revealed potential benefits including faster time to market, reduced cost and increased quality. However, existing literature has mainly focused on the customer's perspective on advantages, disadvantages and factors to be considered when involving suppliers in product development. This paper addresses the supplier's perspective by answering following research question: How do challenges that originate from involvement in customer's product development affect a supplier? The question is answered through a single case study at a supplier that develops and manufacture products primary used in capital goods. Thirteen challenges are identified, classified as being internal or external, and categorised into five areas: (A) Customer requirements, (B) Information exchange between customer and supplier, (C) Product variety management, (D) Design- manufacturing integration and (E) Processes and work instructions. The findings suggest that internal challenges need as much attention as external ones that originate from the customer. Also, an indication of when the challenges affect the supplier during product development is presented.

    Supporting Decision-Making in the Design of Production Systems: A Discrete Event Simulation perspective2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Manufacturing companies are introducing process innovations, namely new production processes or technologies, to achieve increased competitiveness. Production systems design can ensure the fulfillment of process innovations. However, literature shows that the staff responsible for the design of production systems face unfamiliar circumstances, lack of consensus or understanding (equivocality), and absence of information (uncertainty). Hence, manufacturing companies find it difficult to support decision-making in the design of production systems leading to increased competitiveness. One way to support decision-making during production systems design is through discrete-event simulation (DES). However, there is limited understanding of the application of DES in decision-making support, in this context.

    Therefore, the purpose of this thesis is to support decision-making through DES in the design of production systems involving process innovations. To this end, the thesis reviews the current understanding of production system design, including decision-making and DES. This thesis adopts a qualitative case study method to extract empirical data from three production systems design projects of a manufacturing company in the heavy vehicle industry.

    The thesis offers several contributions. Firstly, the findings identify the conditions of use, challenges, requirements, and activities essential for the utilization of DES during production system design related to process innovations. These important findings are critical for supporting decision-making when manufacturing companies renew their production processes. Secondly, this thesis reveals that determining the conditions of use of DES for supporting decision-making rests on the structuredness of a decision (e.g. its degree of equivocality or analyzability), and the quantitative or qualitative nature or DES models. Thirdly, the results describe four novel findings about the challenges undermining the use of DES including equivocality, uncertainty, and the lack of a structured approach and the absence of resources for DES use. Fourthly, the results reveal three requirements necessary for the use of DES including analyzing information consensus, specifying the activities of conceptual models, and coordinating DES models with the information needs. Fifthly, this thesis provides three valuable findings describing additional activities in the design of production systems related to defining the objectives of DES models, and facilitating a structured approach and the management of resources for the use of DES.

    This thesis present a framework that contributes to the use of DES for decision-making support at manufacturing companies. Based on this framework, managers of those companies can supervise formal activities involving the use of DES in production systems design.

    Challenges of Discrete Event Simulation in the Early Stages of Production System DesignIngår i: International journal of industrial engineering, ISSN 1072-4761, E-ISSN 1943-670XArtikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study analyzes the challenges of applying discrete event simulation in the early stages of production system design. Highlighting the implications of new production processes and technologies leading to improved competitiveness, this study provides novel contributions to the understanding of discrete event simulation based on three case studies of the transformation of legacy production systems in the heavy vehicle industry. The findings of this study show that equivocal or ambiguous understanding about new production processes or technologies, and uncertainty about necessary data input and the interrelation of subsystems in production, are critical in addressing discrete event simulation-related challenges. These findings highlight the need for an established process to manage assumptions and simplifications during the design, development, and deployment of discrete event simulation models as a countermeasure against uncertainties, improving manufacturing system design and practice.

    Towards a Reduction of Uncertainty in Production System Design Decisions2016Ingår i: Swedish Production Symposium 2016 SPS 2016, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    A tenet of production system design is to increase a manufacturing company’s competitiveness by introducing novel processes, technologies, and products. However, uncertainties exist regarding the actual benefits that can be attained when novelty and change are introduced into a production system. Addressing this issue, this paper explores how manufacturing companies can reduce uncertainties that challenge production system design decisions when significant changes are introduced into the production system. A real-time case study at a Swedish manufacturing company that decided to change its existing product specific assembly system to a multi-product assembly one was performed. Empirical results identify uncertainties challenging production system design configuration, and the activities targeting reduction of uncertainty. To extend current theory, empirical case study data is synthesized with current findings in production system design decisions, and uncertainty reduction in product design decisions. The paper concludes that information acquisition, uncertainty prioritization, project member background, and complexity of change influence uncertainty reduction in production system design decisions. Managerial implications highlight the importance of information acquisition and a structured approach when reducing uncertainties necessary to achieve an efficient and effective production system design. Thus, academic approaches to uncertainty reduction could benefit manufacturing practice.

    What guides information consensus? Approaching the reduction of equivocality in process innovationsIngår i: International Journal of Manufacturing Research IJMR, ISSN 1750-0591Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study investigates the achievement of information consensus and the reduction of equivocality in process innovations. Drawing on the operations management literature, a new framework to guide information consensus in the reduction of equivocality in process innovations is proposed. The analysis is based on a real-time case study in the heavy vehicle industry. The results show that information consensus is not achieved by a single event, but active work towards this goal is necessary, and a clear set of pre-requisites is needed for achieving information consensus. The concepts of strategic objective, decision areas, and external and internal fit are identified as pre-requisites for achieving information consensus about the purpose, characteristics, and functionalities of process innovations.

    A Virtual Verification Approach Towards Evaluating a Multi-Product Assembly Systems2014Ingår i: Swedish Production Symposium 2014 SPS 2014, Göteborg, Sweden, 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Growing operational complexity and higher variety of products require flexibility in assembly. Despite its many benefits flexibility is a complex concept that requires evaluation to harness its full potential. This study uses virtual verification tools as enablers of the decision making process for production system design of a flexible multi-product assembly system. A case study approach analyses a flexible assembly concept for the earth moving equipment industry through a visual and a discrete event simulation model. The paper also discusses the challenges faced by virtual verification tools when applied to the evaluation of flexible assembly systems.

    Simulation-based Optimization for Facility Layout Design in Conditions of High Uncertainty2018Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 72, s. -339Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite the increased use of Simulation based Optimization, the design of facility layout is challenged by high levels of uncertainty associated with new production processes. Addressing this issue, this paper aims to understand the conceptual modeling activities of Simulation-based Optimization for facility layout design in conditions of high uncertainty. Based on three in-depth case studies, the results of this paper show how characterization criteria of production systems can be used in conceptual modelling to reduce uncertainty. These results may be essential to support managers and stakeholders during the introduction of new production processes in the design of facility layouts.

    Revisiting challenges in using Discrete Event Simulation in early stages of Production System Design2018Ingår i: International conference of advances in production management systems APMS, Springer, 2018, Vol. 535, s. 534-540Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents challenges of using discrete event simulation when supporting decision in early stages of production system design, when significant changes are introduced. It was based on three real-time case studies performed at one manufacturing company during 2014-2016. Challenges in the cases were mapped to previous literature, pointing out discrepancies and highlighting three additional challenges, specifically related to issues in the early stages of the pro-duction system design process. The significant change introduced to the assembly system, and the early phases of evaluation put significant challenges to the use of discrete event simulation and the study points out further efforts needed to support manufacturing companies under change, with an established industrial structure and legacy systems to consider.

    Simulation in the Production System Design Process of Assembly Systems2015Ingår i: Winter Simulation Conference 2015 WSC15, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Effective production systems are necessary for companies to achieve competitiveness in manufacturing, and the production system design process is fundamental to meet this goal. Discrete event simulation is a tool that can support the production system design process. However, few empirical studies have shown the use of this tool prior to the verification of an already chosen alternative, or an implemented production system solution. There is a need to explore how discrete event simulation can be used in the production system design process. A case study at a global manufacturing company, that used this tool in the design of its assembly system, is presented. The results of this study show where and for what purpose were the DES models used for in the production system design process. This study concludes that DES can support this activity and suggestions for future research are made.
