    Optimizing Demand Planning Process: Challenges, Benefits, and Improvement potentials within Judgment Forecast Adjustments2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of the thesis is to explore optimization of the demand planning process with focus on the judgmentally adjusted forecasting approach. The exploration of the system operator perspectives was focused upon for potential optimization actualization. As demand planning is an essential supply chain management process, this thesis contributes to the supply chain management literature and practice by supporting improved sustainable balancing of supply and demand plans. This retains sustainability implications, thus also contributing to the domain of sustainable supply chain management.

    Method: A case study research design was applied involving a large Swedish manufacturer that utilizes the forecasting approach in question. Data collectiontechniques involving participant observations, several types of interviews, anddocument analysis were utilized. Analysis methods included reiterative thematic analysis and Design of Experiment. Software based coding through mixed inductive and deductive approach was conducted for deriving themes and variables which werefurther analyzed by full factorial simulation experiments.

    Findings: Several themes were identified in the data in which challenges, benefits, and improvement potentials were identified and encapsulated in a framework based on system operator perspectives. Through statistical experimental analysis, it appeared that taking these system operator perspectives into consideration for demand planning process optimization can constitute promising potentials. These include correctidentification of relevant refinement variables for enhancing the system forecast adjustments quality.

    Implications: Identifying challenges leads to mitigation. Understanding benefits allows for enhancement. Exploring improvement potentials leads to actualization. Hence, the demand planning process, in regard to this approach, would be optimized. With optimization, it would be easier to maintain the right levels of inventory, order numbers and quantities, and transportation miles, while increasing service levels by minimized backorders. Therefore, sustainability is to be supported by minimized costs and elevated service levels (economic sustainability), enhanced operational and logistics planning (environmental sustainability), and taking workers’ perspectives into consideration to improve their work task and serve customer needs better (social sustainability).

    Limitations: As is the case with research involving interviews, participant perspective involves perception filters that can dim the objectivity of the findings. This, however, was mitigated by applying quantitative data gathering and analysis. The forecasting approach explored is especially suitable for planning demand of components like spare parts. Similarly, other types of assortments and forecasting approaches can be explored for demand planning process optimization.

    Lean implementation in the geriatric care sector in Sweden2015In: International Journal of Six Sigma and Competitive Advantage (IJSSCA), ISSN 1479-2494, E-ISSN 1479-2753, Vol. 9, no 1, p. 56-71Article in journal (Refereed)
    Abstract [en]

    The aim of this research is to examine how lean has been implemented in the geriatric care sector in a municipality in Sweden. The research focuses on implementation experiences and challenges encountered. The research method used is a case study using interviews and observations for data collection. The findings indicate that there are many advantages of lean in the geriatric care sector, such as better communication, organisation and workflow. The lean implementation worked as an eye-opener and created a situation, where the employees realised a great deal of waste in the daily operations. In addition, lean tools helped to reduce the waste. The findings also indicate that there are some challenges of lean in the geriatric care sector, such as the difficulty to create long-lasting lean commitment. A lack of follow-ups, decreasing interest from senior management and lack of a holistic view were the main issues in the case organisation.

    Kartläggning av sjukfrånvaro på en distributionscentral2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this study is to identify patterns in the absence due to illness at a distribution center with higher absence due to illness compared to other companies in the same industry, and to investigate how managers work with routines for absence due to illness. To achieve the purpose, it has been divided into two research questions:

    1. Which patterns in absence due to illness can be found at a distribution center with higher sick leave compared to other companies in the same industry?

    2. How do managers work with routines regarding the absence due to illness at a distribution center with higher sick leave compared to other companies in the same industry?

    Method – Theories about sick leave, work environment, psychosocial health, motivation, organization and leadership were collected to fulfil the purpose of the study. A case study was carried out to collect empirical data on the basis of interviews and document studies which then were compared with the theory for further analysis.

    Findings – The study identifies patterns that were found after mapping the statistics of the absence due to illness on the case company. The result shows that women have higher absence due to illness than men, mostly younger women and older men. Permanent and temporary employees have more absence due to illness than workers on deputy posts and that employees who have worked one to three years have more absence due to illness than other groups. The mapping also shows that employees have the highest sick leave in the fall, on Mondays and only one day is most prevalent. There are clear routines regarding sick leave and rehabilitation at the case company. Improvements can be made with the documentation in the web-portal for sick leave, how the first day reporting sick should be done, and that a comprehensive action plan could be designed for managers to use. The study shows that the managers who are committed and have a higher focus on creating a good group dynamic through activities generally have lower absence due to illness. By creating a satisfying work environment where employees have the opportunity to participate, influence, take responsibility, develop and be seen and heard can therefore improve productivity, motivation and workplace health.

    Implications – A mapping of absence due to illness can improve the same work on other companies and create a greater understanding of why some groups have higher absence due to illness in the workplace than others. This case study also shows that the work environment, motivation and leadership are essential to encourage health in the workplace which can be applied on companies in several sectors.

    Limitations – Deviation may have occurred as a large amount of data during the study was processed. To do a mapping is considered generalizable but the result may differ between companies, therefore is the study not applicable in all contexts. The authors consider however that the study could be applied in general to other businesses as work environment and absence due to illness is an issue in all industries.

    Att upptäcka överfall med hjälp av en mobilenhets GPS: En experimentell studie om hur väl en mobilenhets GPS kan upptäcka fysiska överfall2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose - To avoid a manual interaction required to activate an assault alarm in today'ssolutions, the purpose of this study is to investigate how well it is possible to detect aphysical assault using a mobile device's GPS.

    Method - An experimental study where the study's experiment was designed after atheoretical framework was established where previous studies on GPS accuracy havebeen reported. The experiment is then tested using three different use-cases for whenan alarm should be triggered or not.

    Results - The results of the study indicates that GPS functionality for detecting physicalassaults works to varying degrees. To detect if a user deviates outside a certain radiuson a route, the best possible outcome has an 80% positive predictive value. When itcomes to detecting whether the user has not moved on the route, the result shows thatall tests have a result with a sensitivity of 100%.

    Conclusion - The study's conclusion shows that it is considered possible to use the GPSto detect the scenarios where the user has suffered an “immobilization reaction” duringan assault to avoid the manual interaction that today's solutions require. However, thepositive predictive value is too low to be considered to meet the requirement to detectassaults in the scenarios the user deviates from the route.

    System properties to address the change propagation in product realization2020In: Transdisciplinary engineering for complex socio-technical systems – Real-life applications: Proceedings of the 27th ISTE International Conference on Transdisciplinary Engineering, Warsaw, Poland, 1-10 July 2020 / [ed] J. Pokojski, M. Gil, L. Newnes, J. Stjepandić & N. Wognum, Clifton, VA: IOS Press, 2020, Vol. 12, p. 343-352Conference paper (Refereed)
    Abstract [en]

    Demanding markets and complex products are only some of the reasons that make changes and variations inevitable through different stages of product realization. From early phases of product development to downstream production phase, these changes or variations cause failure either directly or by propagating to other phases, triggering more fluctuations like the well-known butterfly effect. In this paper, first, the definition of changes in product realization will be reviewed and then different papers and their classification on change related system properties (illites) will be discussed and compared. It was argued that considering a system-level view, one could trace these propagations in the systems as a result of not being robust, flexible, or adaptable, etc. Some of the ambiguity in this semantic field demonstrated and most repeated definitions are identified as the unanimous and agreed-upon definitions in the literature. In the end, a historical comparison of the three identified properties presented. The results of this study help us to understand the multidisciplinary nature of these propagations and identify their stemming turbulent environment. This will be used as a foundation for forthcoming research either to prevent these propagations or utilize their attributes in the product realization.

    Produktutveckling i stadens tjänst: en explorativ studie om design av souvenirer2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    It is increasingly important for cities to attract visitors, potential new residents and businesses. Jönköping is one of the cities working with place marketing, a strategy that intends to mediate a positive image of the city, in order to accomplish just that.

    People often have a need to preserve the memory of a trip into something tangible. Anyone visiting Jönköping encounters a souvenir choice, much like the one in many other cities. Linked to the idea of positive place marketing, our work aims to investigate how we as product developers can create a product that en¬hances the image of Jönköping based on the thought that all residents are con¬sig¬nors. Accordingly, we develop three different products from the residents' own image of the city.

    Our research questions are:

    Based on the photographs, what image of Jönköping do the ambassadors mediate of their own city?

    As designers, what in Jönköping's history versus the image of Jönköping today, can we seize in order to give products for visitors a sense of authenticity?

    As designers, how can we use knowledge of place branding in the development of souvenirs?

    We performed interviews within three different aspects: history, souvenirs and place branding, all focused on the city of Jönköping. The interviews and a work-shop formed the basis for the further design process.

    This work has resulted in three products: the matchbox Det nya Jönköping i en historisk förpackning, highlights an important part in the city's history and becomes a conversation piece. Lek dig genom Jönköping want to show visitors what the city offers, and distinguish it from others, from the on-site. Detaljerna gör staden is an every¬day object and function can get residents to begin to discover the details of their own city.

    Through the use of knowledge and theories of place branding and souvenirs, we would argue that we have found a way to actually catch the residents' image of the city in a number of products. We also believe that it would be able to apply this type of project in other locations to create more authentic and at the same time innovative souvenirs.

    Artificial intelligence in banking: A case study of the introduction of a virtual assistant into customer service2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The usage of artificial intelligence in banking is an important theme within entrepreneurial research. The purpose of the study was to analyse the motivations, challenges and opportunities for Swedish banking institutes to implement artificial intelligence based solutions into their customer service process. The research is based on a case study of the Swedish banking institute Swedbank AB, who introduced an AI based virtual assistant (Nina) to deal with customer requests. For the qualitative study, interviews with Swedish banking customer and experts were conducted. Further, to understand the managerial motivations of Swedbank, a theory of Moore (2008) regarding innovation management was applied. The findings display that Nina improved the service spectrum of Swedbank with the potential of decreasing costs, while maintaining customer satisfaction. Further, the results displayed a high acceptance of new technologies from the customer perspective. This provides the foundation for Swedbank to introduce further artificial intelligence based services. Banking institutes and other service oriented organisations with high customer interaction can use the implications of the thesis when considering to more effectively handle customer requests.

    Glödljus vs. LED-ljus: En rumslig analys av ljuskvalitén i hemmiljö2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are still too many households in Sweden that use mostly incandescent light for lighting, using incandescent or halogen bulbs. This causes a substantial part of the unnecessary surplus of carbon-dioxide that is one of the reasons for global warming. Therefore, this degree project aims to promote a greener environment by studying and paying attention to factors that have an influence in the lighting context.

    The purpose of this degree project is to gain a better understanding of how the LED light is experienced in a home environment. The work will show how LED light source's current quality is evaluated based on individual room experiences, and if additional quality improvements are needed. The objective is to turn the public's attitude in a more positive direction where LED can contribute to a more ecologically sustainable environment.

    To investigate how LEDs are perceived in home environments an experimental study was performed which was based on the following research questions: How is LED light quality experienced compared to halogen light, how is personal wellbeing perceived in relationship to halogen and LED light, how are room experience and room character affected if halogen light is replaced by LED light in a home environment and are there any differences in these experiences between lighting designers and non lighting designers?

    Two identical test-rooms were used. They were identical in size, interior design and lighting design. Halogen bulbs were used in one room and LED lights were used in the other room. A survey was used to get answers to the questions above. The results have been analyzed and detailed room analysis was also made.

    The results showed that the light, regardless of light-source, influenced the participant's well-being and their room experience in different ways, depending on the occupational group they belonged to. It was also found that the difference in quality of light between halogen light and LED light is no longer significant. The presently available LED lights are improving and are worthy replacements for incandescent and halogen lamps.

    Internet of Equipment: Enhancing customer value and experience2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Organizations are continuously challenged to create differentiated customer value and experience to increase profitability and gain competitive advantage. At the same time, the fast-paced advancement of technologies provides the opportunity to the organizations to create a differentiated customer value by offering innovative products and services. Internet of things (IoTs) is one such emerging technology that brings within itself opportunities and challenges to be addressed. However, so far research has not sufficiently followed how the utilization of IoTs can enhance customer value and experience.

    Purpose: The purpose of conducting this study is to explore how the utilization of IoTs enhance customer value and experience in an equipment manufacturers context and what are the associated opportunities and challenges. The study also aims to contribute to gap identified in the literature about how organizations can utilize IoTs to enhance customer value and experience.

    Method: The qualitative study utilized a single instrumental case study to explore the research questions. The data is collected by conducting semi-structured in-depth interviews.

    Conclusion: The study reveals that the utilization of IoTs can significantly improve customer value and experience in many ways. This may involve enabling user to monitor, control and optimally use the equipment, sharing useful information, allowing value co-creation and synergistic values and finally by providing autonomous equipment’s or solutions. However, the study also reveals that the utilization of IoTs also pose certain challenges along with the opportunities which must be carefully evaluated.

    Abstract [en]

    The result of an increased population is, among other things, that there is more traffic. This can cause delays for the blue light personnel, as the risk of accidents or obstacles on the way to the accident site also increases. 

    The goal of the report is to study two different lighting solutions that interact with emergency staff and how it operates in the fields. One aims to be able to provide blue light personnel with more light on the roads during calls with the help of a GPS function, connected luminaires and lighting control. The second solution refers to the police being able to provide public places with more light if necessary. In order to investigate as much of the area as possible in which the emergency personel operates, the possibility of providing emergency personnel with the function of increasing the light level on both selected roads and public places, such as squares, is being investigated during calls. The report will also examine the strengths and weaknesses of the various functions. The methods used to answer the research questions are interviews and document collection. 

    Results show that in a connected smart city, lighting contributes to collaboration with emergency staff, luminaires can become information carriers and control of these can take place both directly from the emergency vehicle as well as remotely or automatically.The report mentions a specific traffic lighting solution and systems called chaos lighting. The system functions are used both when an accident occurs and for preventive purposes. The primary purpose of the systems is to minimize accidents and crime. 

    The two systems have similarities and differences. The basic principle of both functions is the same, they enhance selected places with more light to facilitate accessibility for emergency staff and reduce accidents and other disturbances.

    Förslag på effektiv materialstyrning2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Då konkurrensen på marknaden ökar måste företag se över sina kostnader för att kunna bli effektivare och attraktivare för kunden. En effektiv lagerstyrning har en betydelsefull inverkan på verksamheters lönsamhet och kombinationen av effektivitetsvariablerna kapitalbindning, kundservice och kostnader kan orsaka målkonflikter samt komplex lagerstyrning.

    Syftet med denna rapport är att utreda och föreslå förslag på materialanskaffningsprinciper som kan effektivisera företagets nuvarande lagerstyrning med hänsyn till säkerhetspolicy, genomsnittlig kapitalbindning samt lagerhållningskostnad per år.

    För att uppnå syftet har litteraturundersökningar gjorts parallellt med empiriska utredningar på det aktuella företaget. Datainsamlingen har skett utifrån intervjuer, observationer samt datainsamling ut företagets affärssystem. De metoder som därefter har används för att frambringa ett resultat är grundade på beprövade teorier.

    Ur företagets artikelsortiment har 1716 artiklar analyserats och klassificerats utifrån en ABC-analys med flera kriterier, volymvärde samt antal uttag från lager år 2011. Ur klassificeringen har nio olika delgrupper fastställts och artikelgrupperna har därefter analyserats vidare i syfte att få fram en lämplig materialstyrningsprincip för respektive grupp. Tjugo representativa artiklar har valts ut för djupare analys med avsikt att jämföra de föreslagna styrningsprinciperna med företagets nuvarande i avseende på genomsnittlig kapitalbindning i färdigvarulagret samt lagerhållningskostnad per år.

    Rapportens slutsats är att om företaget ändrar sin nuvarande lagerstyrning och tillämpar de föreslagna styrningsprinciperna för respektive artikelgrupp skulle besparingar göras på de analyserade artiklarna. Den genomsnittliga kapitalbindningen skulle därmed sänkas med 85 % och lagerhållningskostnaden skulle reduceras med 82 %

    Levels of Interaction in Supply Chain Relations2007Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    To be able to retain the manufacturing industry durably, in Europe in general and in Sweden in specific, manufacturing companies have to be competitive also on the global market. One way for companies to realize this ambition is to interact with suppliers and customers in different kinds of supply chains. In the dyadic relation between two companies, three different levels of interaction have been identified. To be able to enhance the competitiveness instead of requiring excess workload, the level of interaction has to be adequate for the specific company and their market conditions.

    The aim of this thesis is to clarify the characteristics of supply chain interaction, both in terms of different levels of interaction and concerning the factors affecting the appropriate level of interaction. A basic prerequisite to enable companies to select an appropriate level of interaction within their supply chain is also to clarify the present use of terminology.

    This research is conducted through theoretical studies. The theoretical findings are synthesized in order to fulfill the research objective.

    Characteristics of supply chain interaction in terms of affecting categories and factors are identified. The factors are sorted according to the category they support. An interaction framework that can be used to gain an overview over the categories and factors affecting the level of interaction in a specific situation is developed.

    The resulting interaction framework is aiming at industry applicability but is based only on theoretical studies (which in turn are based on empirical data).

    The aim is to support the interaction level decision for, primarily, small and medium sized manufacturing companies in order to increase their competitiveness.

    Despite the amount of research within the supply chain area, the question how companies should select the way to interact within their supply chain has so far been left unanswered. In this thesis, a number of categories and factors that affects the appropriate level of interaction are identified and listed.

    Purpose – The purpose of this report is to find out which frameworks and methods are most popular and most widely used, as well as web developers' views on the hamburgermenu.

    Method – In order to answer the questions in our report we used the methods quantitative statistical processing, quantitative analysis of data collected via survey and qualitative interviews with web developers. The study was conducted to find out which frameworks and methods are most popular and used most, as well as how web developers look at the hamburgermenu. This was done by analyzing the popularity and usage of different frameworks as well as interviewing web developers who work with it daily.

    Findings – The results of the report are based on the data collected through the processing of the statistics, the analysis of the survey, and the interviews performed. The result shows which frameworks are most popular and those that are most used. The following list shows the ranking:

    Most popular:

    1. Bootstrap
    2. Semantic UI
    3. Materialize
    4. Material Design Lite
    5. Foundation

    Most used:

    1. Bootstrap
    2. Foundation
    3. Materialize
    4. Material Design Lite
    5. Semantic UI

    The results of the interviews showed that most of the web developers interviewed used a framework when they created a website, either an existing or one of their own. It was also a practice to use the same framework in the company, although the way it was used was different from developer to developer. All developers had a mobile-first thought in mind, although it was not always a priority.

    It was also found in the study that everyone had a basic idea behind the choice of framework, but only one who had performed a study on which one would suit them best.

    All web developers interviewed thought that the hamburger menu was boring and bad from a user experience perspective. But everyone also agreed that because it is so widely used and has been for a couple of years, users have learned what it means and therefore fulfills its purpose.

    Implications – The use of the results is primarily linked to individuals or companies that work with web development, but can also be used by private individuals. For the report's primary target group, the results will give an increased understanding of the most used framework and an increased understanding of why these are used. Private individuals can use the result in the same way.

    Limitations – The limitations we receive in this study are that we cannot make any conclusions about companies and web developers in other parts of the country using the same framework or methods as the local ones we interviewed. Nor can we make any conclusions about why Bootstrap is the most popular and most widely used framework. We can only speculate why with the empirical we gathered through the interviews.

    A major limitation is also the lack of interviews when we only got answers from 6 of the 10 companies we contacted, of whom 4 would like to participate in the interview. More general conclusions could have been drawn if more companies had been interviewed.

    Keywords – Framework, Web Development, Responsive Web Design, Interaction Design, User Experience, Bootstrap, Foundation, Materialize, Material Design Lite, Semantic UI

    Successfully Implementing Environmental Sustainability Strategies: Important affecting and enabling factors2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this research is to investigate how organizations successfully can implement sustainability strategies. To fulfill the purpose, three research questions were established:

    1. What factors are important to consider when implementing environmental sustainability strategies?
    2. How do these factors affect the implementation of an environmental sustainability strategy?
    3. How can these factors enable a successful implementation of sustainability strategies?

    Method – To achieve the purpose of this study, a case study has been conducted at an organization where empirical data has been collected through interviews, observations, and document analyses. Further, a literature review was carried out to establish a theoretical framework. The empirical data and theoretical framework have been compared and analyzed in order to answer the research questions and fulfill the purpose.

    Findings – The findings provided six important factors in the implementation of environmental sustainability strategies: organizational structure, organizational culture, internal communication, management control, leadership, and employee motivation. The factors affect the implementation by hindering and facilitating alignment, common understanding, efficient communication, employee involvement and motivation. Further, the factors can enable a successful implementation by creating a mutual understanding of the strategy's vision and goals and establishing an organizational alignment in relation to the strategy. Last, the research indicates that a holistic consideration of these factors is needed.

    Implications – The research did not contribute to new theories, however, it provided increased knowledge on various factors that affect and enable environmental sustainability strategy implementation. Further, the research suggests that the factors should be considered holistically and simultaneously to achieve organizational alignment and mutual understanding.

    Limitations – The study is a single case study where one organization has been explored and a limited number of interviews have been conducted. The credibility of the study is believed to have increased further if multiple organizations had been studied with more interviews.

    AB Småland: En undersökning om kanaler för återbruk åt AB Småland samt möjligheter med miljömärkningar för kommersiell handel.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sustainable development has for a long time been a much spoken topic worldwide and so in Sweden. Sustainable development is about creating a social economic and cultural development and to ensure human well-being in balance with the earth´s ecological system. Nowadays sustainable consumption is also a much spoken topic. Sustainable consumption is about how humans consume, what humans consume and in what way. This means that we carefully need to choose what products to buy and use them as long as they are still alive. Because of human’s unsustainable way of using the resources from earth, we now need to stop using the linear economy and start using the circular economy. This will lower the environmental effect.

    This study aimed to investigate how AB Småland, a company in Malmö, can get customers to hand in furniture to the store for reusing. The company wants to expand their business by collecting second-hand furniture from costumers. In turn, they will sell these furniture at the company’s own auctions. The students' work was to help AB Småland to see what is required of them to get this process working, to get a flow with recycled furniture. The study included an investigation of the Miljönär-Vänlig labels’ options to facilitate consumers to make better choices for a more sustainable consumption in the future. To do research on how consumers think and act was relevant to understand why these behaviors occur in order to understand the value of marketing sustainability. The study also included previous research in the area.

    The study’s two issues:

    [1] How can AB Småland get customers to hand in furniture to the store for recycling? [2] Can a label like Miljönär-Vänlig help consumers to understand the concept for stores that work with sustainability?

    To answer the first issue of the study the students gathered data through interviews with companies that work with the durability to take note of how they solved it. To be able to answer the second issue of the study the students carried out a web survey in which the purpose was to gather information about consumers' attitudes to sustainability and their consequences of consuming. In order to underpin both issues, literatures were used and were carefully chosen to answer the purpose of the study.

    The report presents the results for the study’s two issues that both have all three data collection methods proving them.

    The result from the study’s’ first issue shows that AB Småland should focus a lot on the preparatory work and strategies that will be required to get their new part of the business to be profitable. They have got help with some parts through the proposal of a business model, SWOT analysis, competitive analysis, how to design the "Re-Mill tab" on the website, which the students produced.

    The result from the study’s’ second issue shows that Miljönär-Vänlig is a label that is not suitable for AB Småland in the current situation because it is for those operations where the main part of the business is about "fix, borrow and reuse" in order to minimize waste. It can be a good tool for stores, which work with environmental issues, in order to help the consumer make better choices. But AB Småland can create an own label that shows customers how the company works with sustainable products.

    To get AB Smålands new part of the business profitable, they should consider that it requires thorough preparation. Time is of essence and other resources are needed and the work should not be rushed. Before they start this process, AB Småland should establish and clearly review policies and their business model so everyone in the company can be initiated.

    The students have come to the conclusion that AB Småland has to work with their marketing in order to reach consumers and help them understand the company’s values and concepts.

    Easier travelling with babies in cities, in collaboration with Thule Sweden AB.2020Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Master thesis carried out in collaboration with Thule Group during spring 2020 as part of the Industrial Design Master at Jönköping University. The work aims to develop a new concept idea related to "Active with kids" and focused on the Southern Europe market (Spain). The goal of the project is to improve the parental active experience in metropolitan areas concerning strollers or their accessories. The product proposal will fit and express Thule vision and brand language. This project is written in the field of industrial design; therefore, we will go over the usual design process: empathize, define, ideate and prototype. The project will be done individually, however, the beginning of it (empathize and define), will be carried out in pairs between Nerea Cuello and Berta Cester, to achieve broad research and obtaining two different products within a similar market. The project starts with a design brief formulated by the company and continues into understanding the problem by investigating the brand, the user, the market, and other interesting factors. Continuing with an ideation phase that explores different problems and ideas. The process will end with a final concept presented as a physical prototype. The final result is a new concept solution for easier travelling with babies in urban cities, improving parents' lifestyles when they cannot use or find it difficult to use a stroller

    Barriers in the Initial Acceptance Phase to Life-Cycle-Assessment: A Case Study of a Swedish Manufacturer2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Sustainability and sustainable manufacturing has grown in importance in recent years, and more legislation and demands are put on organizations to show how their operations affect the environment. Life cycle assessment is a proactive and efficient sustainability tool to report a company’s effects on the environment. Nevertheless, life cycle assessments of products and organizations are complex and require significant resources. Therefore, the purpose of this study is to investigate what potential barriers can occur within the initial acceptance phase when implementing life cycle assessment in the manufacturing industry.

    Method: This research project is a single case study of a Swedish manufacturing company. The theory was deduced from literature where eight internal factors influencing the implementation of tools and systems created a foundation for data collection and analysis. Five semi-structured interviews and unstructured observations have been conducted to collect empirical data.

    Findings: Nine second-order themes of factors influencing the project as barriers have been identified that construct the three aggregate dimensions ̈Lack of management support ̈, ̈Lack of resources ̈, and ̈Lack of interdepartmental coordination ̈. From the empirical findings, it is also suggested that the three aggregate dimensions are interrelated. The interrelationships are later used to find three change suggestions to mitigate the barriers by using the relationships between the dimensions and targeting as many barriers as possible. Namely, ̈educate top management ̈, ̈enhance the education of project participants ̈, and ̈spend more time on project planning ̈.

    Implications: This study provides a deeper and more detailed understanding of different barriers within the initial acceptance phase of a project. It also gives further insights into various interrelationships between barriers and how one dimension can influence the other in both positive and negative ways. Furthermore, this study's findings can guide managers and practitioners in preparing for a project aiming to implement a tool or a system.

    Limitations: As in all interpretative research, the interpretations of the empirical data are based on subjective thoughts influenced by the researcher’s positionality, the relationships with the participants, and preconceived perceptions. Furthermore, this research project is a single case study, and the results apply to this case. The findings cannot be statistically generalizable, meaning that the theories and themes created in this report should not be seen as absolute truths but instead as suggestive theories within the field.

    Virtual influencers: Anonymous celebrities on social media2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Virtual influencer is a new phenomenon operating on social networks. Since this is new, there is not a lot of research about that field. Therefor the purpose of this study is to get a better understanding about virtual influencers and how they operate on instagram. Which will be done by identifying which key factors that needs to be considered in the process of creation and management of a virtual influencer.

    Experiment has been used as a method. A virtual character has been created as well as its account on instagram. During 2 months, data has been collected and has revealed that there are different factors that can impact the creation and management of a virtual influencers account. The key factors that have been identified are the realism of the character, the changing algorithm of instagram as well as the accounts content itself. Firstly, the character should be realistic but the fictional part of it should be at least noticeable in order to generate curiosity. Secondly, the instagram algorithm makes a difference if it is managed right. The last key factor is the content of the account itself; it needs to be adapted to the audience and the content in the posts as well as the overall aesthetic of the feed need to be visually appealing in order to raise interest.

    External Social Capital for Post-Campaign Commercialization: A multiple case study on Crowdfunded Sustainability-oriented ventures.2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sustainable entrepreneurs are a relatively new breed of entrepreneurs who use innovations to tackle environmental and societal challenges. Because their ventures focus on sustainable value creation rather than financial performance, crowdfunding is a novel method of fundraising that helps these sustainability-oriented ventures get the capital they need through campaigns conducted on online reward-based crowdfunding platforms such as Kickstarter and Indiegogo. There is adequate research about their funding, but little investigation exists about how they commercialize their ventures post-campaign. We believe that the social capital theory provides a promising lens to deeply understand this period. In particular, this paper argues that social capital arising from outside of the crowdfunding platforms (i.e. external social capital) has a strong influence on the overall post-campaign commercialization activities, which include the broad categories of continued production, logistics and marketing. A qualitative abductive case study research with five crowdfunded ventures offering sustainability-oriented products is conducted in order to derive a deeper understanding about this niche. Findings are compared with current literature in order to reveal that two particular dimensions of social capital play the most crucial role in post-campaign commercialization- External Relational and External Cognitive. These dimensions involve different relational and cognitive facets that come into play between the sustainable entrepreneurs and the external social capital, facilitating the post-campaign commercialization process.

    Dating of fashion plates (1820-1880) using transfer learning: Recognition of the year of origin of fashion plates2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Fashion history is an integral subfield of history as a whole. Fashion plates provide important evidence of what fashion once looked like and as such are a valuable window into the lives of the people in ages past. The rise of digitization opens new avenues for aiding historians in the dating of fashion plates; following on from this, digitization also brings a greater need for artworks to be digitized and AI can be utilized in order to keep up with the demand. This provides unique challenges such as gathering data and working with a relatively limited database. Due to the lack of prior research into the subject of dating fashion plates using Artificial Intelligence (AI), said application of AI in the dating process could help future historians automate the task. Transfer learning can help streamline the dating process of fashion plates. I used several approaches with three different models (ResNet101, NasNetMobile, and InceptionV3) and achieved the best mean absolute error of 2.8 years in a range of 60 years using NasNetMobile with a simple output layer and no fine-tuning.

    Abstract [en]

    Transportation of heavy objects can lead to back injury. High Performance batteries must be handled with care. Therefore, the focus on the product development process is on ergonomics and safety.The present report presents the product development process of a mobile battery systemfor Globe Technologies. It presents the literature review of load carriage systems and ergonomics. The project followed a double diamond design approach to come up with a proposed concept design, presented to the company with a CAD model and physical prototype.The design process started with the finding of a product opportunity. The need to transport the batteries used to power Globe Technology’s battery-powered power tools. The weightof the batteries posed a challenge, ranging from 2.2 to 3.5 kg each.The product concept was developed in 7 cycles of alternating ideation and workshopscarried out at Globe Technology’s offices in Jönköping. The proposed solution is a 3-part system of two battery cases that can hold 3 batteries each, a backplate to which the cases are mounted, and a harness that consists of padded straps and a hip belt. The final concept was considered satisfactory and the product design process valuable. However, further detailing and testing would be necessary before having a viable product for manufacturing.

    Supply Chain Integrations viktiga principer2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this study is to explore the concept, Supply Chain Integration (SCI) based on a buyer-seller perspective. To fulfil the aim, three research questions have been formulated:

    • Which principles are important within the concept of SCI and how does the buyer and seller relate to them?
    • Which challenges does the buyer and seller identify when working with integration?
    • How does the buyer and seller work with integration?

     

    Method –  To fulfil the aim and answer the research questions, a qualitative approach has been adapted to the study with the help of an inductive approach. This means that the results of the theoretical framework and the empirical data have been analyzed based on SCI:s principles and challenges.

     

    Findings – The study shows that the concept must be established and distinguish the important principles within the subject to be able to facilitate the concept practically in a business. The most central part of the results appears to be the requirement settings that have a major impact on the integration. Companies must therefore take this into consideration.

     

    Implications – The concept SCI is very vague because many researchers use older sources that are still up to date. This indicates that it is a difficult concept to determine and where new research shows what has already been established by older sources. The theoretical implication with the study has been to identify the important principles for SCI, which can be further managed in later research. The study contributes to increased understanding of how a successful SCI can be achieved and how it can be further developed to create a more realistic concept. The empirical implication of the study is that companies should create a greater understanding of the concept SCI in order to create an interdependent relationship between a buyer and a seller in a supply chain.

     

    Limitations – The study has generated a more general result. The reason for this is that the study focused on three case companies their perspective on subject SCI. The companies operate in different industries and because of that, very general information has been collected which leads to the general result.

     

    Keywords – Supply chain integration, key principles, consensus, long-term relationship, information sharing, power, requirements.

    Förståelse för materialflödets påverkan vid maskininvestering: Process för utredning av materialflödets påverkan vid investering i alternativ produktionsutrustning i små- och medelstora tillverkande företag2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – In order for companies to remain competitive there is a need for constant improvements and an alternative is to invest in new production equipment. It is essential to evaluate the investment appraisals impact on the material flow, since an inadequatedecision might result in devastating consequences. Hence, the purpose of the study is to develop a process that existing manufacturing SMEs can use to evaluate how the material flow is affected of investments in alternative production equipment. Based on this purpose, three research questions were formulated as:

    1. What factors affect the material flow when investing in alternative production equipment in existing manufacturing SME?
    2. How do these factors affect the material flow when investing in alternative production equipment in existing manufacturing SME?
    3. What steps should a process for investigating the material flow contain when investing in alternative production equipment?

    Method – To achieve the purpose of this study two methods were used where a case study has been conducted to answer research questions 1 and 2, and analytical conceptual research was used to answer research question 3. Empirical data has been collected through the three data collection techniques interview, observation, and document study. Further, a literature review has been carried out which was the basis for the theoretical framework. To answer the research questions and fulfill the purpose, the theoretical framework and the collection of empirical data have been analyzed and compared with each other through pattern matching.

    Findings – The study resulted in the process, known as the PUMPI process, which investigates the material flow when investing in alternative production equipment. In addition, 7 main factors and 17 sub-factors were identified to be evaluated according to the created process together with a value flow analysis. Based on the study's analysis, the process was identified as containing five steps that investigate the material flow and result in a decision basis for the investment. The basis for the decision should be supplemented with other perspectives, such as the capital budget, so that the decision taken is well-founded.

    Implications – The study provided both practical and theoretical implications. Through the development of the process, that fulfills the purpose of the study, a process was added to the existing ones in the area, which also bridges the gap that exists in the area of material flow – investment - process. Furthermore, the study also made a practical contribution where SMEs can use PUMPI to investigate the impact of the material flow when investing in alternative production equipment.

    Limitations – The study was a single case study where a limited number of interviews and observations were conducted, which may have affected the credibility of the study. Furthermore, the study was limited to examining the material flow, where the information flow and the financial flow were excluded.

    Värdeflödesanalys i ett råmaterialflöde: En fallstudie där icke-värdeskapande aktiviteter och dess orsaksfaktorer identifieras2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose with this study is to map a raw material value flow analysis and identify non-value-creating activities and propound suggestions for improvement.

    Method – The study is a case study based on an inductive approach with quantitative elements. The used methods is of a qualitative character since the study is based on interviews and interpretation based on observations of the basic data collection. The data collection has been done through literature studies, interviews, observations and document studies. In order to achieve high credibility, it has been important that the design of interview questions can be linked to fulfillment of the purpose. This work was done to minimize the risk of systematic errors.

    Findings – The study's results are based on a mapping of a flow where a current analysis was carried out to then later end in a value flow analysis. Based on the value flow analysis, it appeared that a shortage in the flow was high levels of waste. The largest identified waste was a lack of quality, mainly due to the production of defective products. This shortcoming also affects large parts of the flow. The measures proposed in the study are to implement standards through a change in the culture of the company, and to continue to work on continuous improvements.

    Implications – The result, which shows the importance of working with streamlining waste, which in this case leads to a lack of quality, mainly in the form of production of defective products. The study can be seen as a practical contribution to manufacturing companies, by embracing these proposals for action, it should generate a better consensus on the quality of the business. Also a theoretical contribution where further research could look at how to technically and psychologically implement a change like this.

    Limitations – It can be difficult to generalize the results as this is a study conducted as a one-case design. Furthermore, it is also complex to investigate and develop a study that shows how quality is linked to corporate culture.

    Framtagning av ekodesignat produktförslag för Ekdahls möbler2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A balance between sustainable development, classic design and uniqueness can help to reduce today’s consumption. The concept of eco-design includes a product's environmental impact throughout its life cycle without compromising with other components such as quality, cost and design. Creating an innovative eco-designed product without compromising makes it highly attractive and easier for the customer to choose the right product resulting in high customer value where it will live through generations.

    The purpose of the study was to develop a unique eco-designed product suggestion, for the client Ekdahls möbler, that will be used and appreciated by many generations in which the following questions were answered;

    [1] What common factors of success represent classically designed seating furniture?

    [2] How can a unique eco-designed seating furniture be developed?

    To answer the first question of the study a document investigation followed by a connection matrix was done to determine common success factors of classically designed chairs. An interview was conducted to analyze and strengthen the success factors. The result showed that the following success factors were crucial for a classically designed seating furniture; unique, comfortable, qualitative, aesthetic, creative and user friendly which constitute the design language of the final product proposal. To answer the second question of the study a design process was applied in which the integration of eco-design tools in the form of status analysis, requirements specification, functional and lifecycle analysis and the eco strategy wheel created an environmental and tailored process for the development of the study’s product proposals.'

    By following the design process’s every step thoroughly with supplementation of integrated tools for eco-design not only a unique development process was created, but also a unique project towards an eco-designed product. Uniqueness is the success factor valued most. By living up to it as well as the other factors for success in the final product proposal, an opportunity to become desirable in the market was created and thus also increase the longevity of the product.The product radiates classic and distinctive design where the love for natural materials and quality are central. Through its optimization of environmental impact and its unique design language it is a product to proudly live with through several generations.

    Abstract [en]

    Automotive industries are constantly working to streamline their warehousing operations, as disruptions and wastes can have negative effects on parameters such as lead time, warehouse space and utility of warehouse resources. Performance and efficiency in material flow have therefor had a negative impact on the total cost of products handled in the warehouse area. The purpose of this case study is thus to analyze the material flow from goods reception to picking location and identify any disruptions and wastes to suggest improvements. The case study has been conducted on an automotive industry’s warehouse operation.

    The approach adopted in the case study is deductive with methods of data collection via observations, semi-structured interviews and company documentations. This enabled the authors to be able to process both qualitative and quantitative data in the study to present a relevant analysis and discussion. This case study demonstrates that fixing disruptions and wastes in a material flow is a constant process, laying down also the importance of identifying the root cause that can be the cause of several disruptions and wastes, not only in one area but in several different sections of the material flow. Furthermore, it is presented how the material flow can be handled based on the influencing factors of disruptions and wastes as identified in the study, to aid in shorter lead times and reduced cost. One of the findings in the case study is the possible elimination of unnecessary transport that occurs due to lack of information among employees regarding the utilization of storage space in the storage area. By eliminating this waste, it contributes to cost savings, shortened lead times and less environmental impact. The case study also identifies that a root cause may be the basis for several deviations in a material flow, so when handling a root cause several disturbances and wastes can be eliminated.

    During the case study, the authors' observations in the case company were limited because of the prevailing pandemic that caused a visitor ban in the case company during planned observation occasions, thus less observations than planed have occurred.

    Exploring Online Music Listening Behaviors of Musically Sophisticated Users2019In: ACM UMAP 2019 Adjunct - Adjunct Publication of the 27th Conference on User Modeling, Adaptation and Personalization, 2019, p. 33-37Conference paper (Refereed)
    Abstract [en]

    Due to the rise of available online music, a lot of music consumption is moving from traditional offline media to online sources. Online music sources offer almost an unlimited music collection to its users. Hence, how music is consumed by users (e.g., experts) may differ from traditional offline sources. In this work we explored how musically sophisticated users (i.e. experts) consume online music in terms of diversity. To analyze this, we gathered data from two different sources: Last.fm and Spotify. As expertise is defined by the ubiquitousness of experiences, we calculated different diversity measurements to explore how ubiquitous (in terms of diversity) the listening behaviors of users are. We found that different musical sophistication levels correspond to applying diversity related to specific kind of musical characteristics (i.e., artist or genre). Our results can provide knowledge on how systems should be designed to provide better support to expert users.

    Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.

    This study examines if lighting should be adapted after the individuals’ need or if a general value can be found that will cover every individuals’ need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1’s recommendations.

    The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience. The test subjects did perform a test where they estimated their individual need for lighting in office environments regarding lighting for workplace and its surroundings. Every test subject carried out the test where they repeated the same attempt three times, to establish if the individual lighting need oscillated or if it was constant, whereupon the results were analyzed, compiled and compared to standard SS-EN 12464-1.

    The results show that the minim- and maxim value for the test subjects is between 70 – 4300 lux. The result varies with different parameters such as sex, age and glasses/lenses. We could also state that the relationship between workplace- and surrounding light levels is slightly higher than what standard SS-EN 12464-1 recommends, which should be taken into consideration when planning future lighting constructions.

    Based on the results in this study, our conclusion is that standard SS-EN 12464-1 does not cover the needs on the comfort levels that the test subjects indicated. The values that the test subjects indicated differ from the values that standard SS-EN 12464-1 recommends.

    Since there is a huge spread of the experienced need for lighting between individuals and age groups, we draw the conclusion that general values of measure can’t be applied as a standard on neither workplace- nor surrounding light levels. To fulfill the needs that users have, the lighting construction should be adapted for the individual and give a lighting flood that will fill the individual needs for workplace lighting.

    Abstract [en]

    This study is a bachelor thesis that has been carried out as a part of the course in Product Development with focus Lighting Design at Jönköping University, School of Engineering spring term 2018. Every outdoor environment is unique as the seasons and the developing day which in turn makes it complex. The public urban space is frequently used by its inhabitants and visitors throughout the day. The function of lighting is therefore essential for the individual's role of wanting and daring to reside in the urban spaces also during the evening. By emphasizing the spaciousness and atmosphere of different environments along the room and the individual, more comfortable and safe places can be created for both meeting and staying on. The purpose of this study has been to get a profound understanding of how different individuals experience of spatiality and atmosphere with varied light distribution in a public exterior urbanspace. By conducting an experimental full-scale situation on a walkway/avenue in the central parts of Jönköping, four different light scenes could be studied in the same exterior room. This enabled credible and comparable data to be retrieved and then analyzed. The study results show that the human experience is individual and that its movement patterns in a room vary, depending on how the light is set. Further factors as gender, past experiences and site design contributes to how a room is experienced between individuals. It has emerged from the study that whether or not a room is viewed from within or from without perspective, the experience among the participants is perceived equally. Depending on how an environmental dimension is accentuated in terms of its height, width and depth, the perception of the actual creation of the room can be influenced. An even contrast between light and dark creates a more inviting impression, which can contribute to an increased sense of security and facilitate orientation.

    Additive Manufacturing enabled Digital Inventory: Perceived Benefits & Challenges2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Industry 4.0 brings new technologies said to improve organizations’ supply chain performance. Additive manufacturing (AM) and information and communication technologies have received much attention in recent years. A combination of the two has recently surfaced in literature and captured the interest of large manufacturing organizations such as Siemens Energy. Namely, AM-enabled Digital Inventory (DI).

    Problem: AM is considered a new manufacturing method and is still under development, thus, industries have yet to realize AM’s full potential. DI has been presented as a suggested tool to maximize AM’s potential. However, existing research on DI is scarce. For manufacturers to properly evaluate DI and decide on implementation more information is needed.

    Purpose: To aid decision-makers in the navigation of DI implementation, we have conceptually explored practitioners' perceptions of the DI concept and related benefits and challenges. To ultimately allow organizations to obtain the full potential of AM, and thereby increase supply chain performance and remain competitive in the transition to Industry 4.0.

    Method: Ontology – Relativism, Epistemology – Constructivism, Qualitative, Inductive, Exploratory, Single-case study, 8 semi-structured interviews, 10 semi-structured group interviews, Snowball sampling, Purposive sampling, Thematic analysis.

    Conclusion: With this research, we were able to establish that the DI concept should function as a system that allows for easier sharing and access of information. Benefits found: Process optimization, reduced risk, and cost, further development, and increased competitiveness. Challenges found: rules and regulations, change management, operations issues, strategy, profitability, system issues, and post-processing. Ultimately, to obtain the benefits, trade-offs in lead time, capacity cost, and inventory costs need to be considered. Before calculations can commence components suitable to include in a DI needs to be established.

    Abstract [en]

    This paper shows how instructions for the inspections of the lifting tools at Abetong were made. The most important is how the company can ensure that every lifting tool is inspected. The work was carried out at three of Abetongs factories. Abetong makes precast concrete elements, which makes them use liftingtools as a part of their daily work; most of the lifting tools are custom made for the concrete industry.

    A numeric system for the lifting tools was formed and partially implemented. A small investigation to find companies which could do the annual inspections was made. A specification for this was also written. An instruction for the daily inspection of the lifting tools was made. A signing list will be put up at each working area to ensure that the daily inspections are being done. The lifting yokes which lacks label will be risk analysed, this creates some questions about whether this is aloud.

    Abstract [en]

    Abstract 

    Purpose – The purpose of the study was: Understand how system suppliers' projects differ in terms of their complexity and propose guidelines for improved project management. The purpose was broken down into two questions. 

    [1] How do system suppliers' projects differ in terms of their complexity?

    [2] What guidelines can be given based on project complexity for improved project management of system suppliers?

    Method – The choice of method for this study is based on a qualitative case study. The study was conducted at a system supplier. The empirical data was collected through observations and interviews, and then analyzed with theories. 

    Results – The first research question was answered by identifying factors in the system manufacturer's project that caused complexity, combined with factors identified in the research. The second research question was answered by developing guidelines to better manage the complexity of projects, mainly through better management of communication.

    Implications – For system suppliers who have difficulties with project work or feel that their project work would be facilitated by some type of improvement work, this study can be used as a basis for the work. Theories used are generally linked to project work, how it should be managed and carried out when several projects are carried out simultaneously.

    From a practical perspective, this study lays a foundation for how system suppliers can begin to improve their management of projects. The theory this study has contributed is how projects can look like for a system supplier and divided them into different factors based on complexity.

    Limitations – The study has identified factors on projects from an employee perspective in a company. The study is also limited by the fact that the guidelines identified have not been implemented in the case company. Based on this, no conclusions can be drawn about the effect of the guidelines.

    Problem och problemhantering i orderprocessen - För företag som tillverkar kundanpassade produkter med höga kravspecifikationer2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this thesis is to highlight the challenges that exist within an order fulfillment process, in companies that produce customer adapted products with high requirement specifications and how to manage these challenges. The purpose was decomposed into three questions, that all demanded an answer before the thesis could be considered as finished.

    1. How is an order fulfillment process designed in companies that produce customer adapted products with high requirement specifications?

    2. Which problems can be found in the order fulfillment process for companies that produce customer adapted products with high requirement specifications?

    3. How can these problems be managed and thereby achieve a more efficient order fulfillment process in companies that produce customer adapted products with high requirement specifications?

    Method – The thesis empirical data was collected from a case study on the company Mastec Components AB. The data came through interviews, observations and document studies. From that data the best fitted theories were decided, so it became possible to analyze the empiric data with the theories, by comparing them to each other. The thesis result was then able to get from that analyze.

    Findings – Each company’s order fulfillment process is unique, but it is possible to illustrate a general picture of order fulfillment process in companies that produce customer adapted products with high requirement specifications. Because of that every order fulfillment process is unique; its problems also are unique, but you can sort these problems into the general categories: variety, not value added activities and lacking exchange of information. If the problem unique, so is there solutions, but the thesis shows that the solution propositions also can be sorted into more general categories: eliminate waste, standardize and to streamline the exchange of information.

    Implications – This thesis implication is that you can´t, with 100 % certainty, point out any specific problem or solutions to the problems that could be transferred into other order fulfillment processes in companies that produce customer adapted products with high requirement specifications. What this thesis shows instead is that there are more general problems and solutions that can be used.

    Limitations – This thesis is limited because of its propositions of solutions just is propositions. Even if the propositions probably solves most of the problems, they are not tested and therefore you can´t say that they are really working.

    Keywords – Order fulfillment process, process mapping, variety, not value adding activities, standardization, eliminate waste, exchange of information

    Manufacturing strategy in SMEs and its performance implications2015In: Industrial management & data systems, ISSN 0263-5577, E-ISSN 1758-5783, Vol. 115, no 6, p. 1004-1021Article in journal (Refereed)
    Abstract [en]

    Purpose– West European manufacturing has been going through challenging times after the global financial crisis of 2008-2009. Some countries (e.g. Sweden and Germany) have recovered from the crisis, while in others problems and job loss still persist. One of these problem countries is Finland. The purpose of this paper is to examine manufacturing strategy priorities and their performance implications in this country.

    Design/methodology/approach– During the spring of 2014, a web-based survey was conducted, targeting Finnish manufacturing companies. In this study we focus on small- and medium-sized (SMEs) companies and link survey responses to financial performance data, which is available in audited annual reports.

    Findings– Research results indicate that SME manufacturers in Finland put less emphasis in new product development, broadness of product line and after sales service, while showing high priority in delivery speed and punctuality. As the manufacturing strategy dimensions are connected to audited financial data, regression analyses reveal that superior quality is at central place for achieving higher revenues and profits. After sales service has a positive impact on revenues and new product development ability is connected to higher profits. Managing quality to meet specifications (minimum quality level), leads only into higher employment. Some evidence is shown in support of flexibility in terms of product changes having negative impact on revenue, while volume flexibility is connected to lower profits.

    Research limitations/implications– This research is limited to a single country, and is cross-sectional in nature. The primary data were combined with profit and loss statements in order to reduce common method bias.

    Practical implications– It is evident that SMEs may adapt their manufacturing strategy, with emphasis on superior quality together with properly managed after sales service and new product development activity. However, it is worrying that head count in manufacturing SMEs is not connected to same factors, as are revenue and profit. It is suggested that flexibility in labour contracts and other regulatory support measures are needed to support flexible manufacturing.

    Originality/value– Advanced economies and their remaining manufacturing companies have been receiving minor levels of interest in research. This is especially the case with SMEs, where this research tries to fill important research gap.
