    The effectiveness of coping strategies used by entrepreneurs and their impact on personal well-being and venture performance2010Ingår i: Zbornik Radova Ekonomskog Fakulteta u Rijeci : ÄRasopis za Ekonomsku Teoriju i Praksu, ISSN 1331-8004, E-ISSN 1846-7520, Vol. 28, nr 2, s. 193-220Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper analyzes effectiveness of coping strategies that entrepreneurs use to daily manage work related stress. Coping is the process of expending efforts to solve personal and interpersonal problems and reducing stress induced by unpleasant and stressful situations. Two broad strategies of coping are identified; problem-based coping refers to a cognitively-based response behavior that includes efforts to alleviate stressful circumstances while emotion-based coping involves behavioral responses to regulate the affective consequences of stressful events. The purpose of this research is to analyze relationships among the coping strategies used by entrepreneurs and a set of antecedents influencing the selection of coping strategies. The methodology used is based on structural equation modeling and empirical data of 469 entrepreneurs from two European countries. Our results show that problembased coping facilitates well-being and venture performance. In addition, our findings also support interaction effects of founder centrality and contextual conditions of venturing on the extent entrepreneurs engage in coping. We believe that our insights can help in training entrepreneurs in the development of effective coping strategies that are context dependent. In specific, our results suggest entrepreneurs to engage in problem-focused strategies when they want to effectively address the economic aspects of their lives whereas when they engage in emotionbased strategies they seem to increase the self-knowledge they need to start subsequent ventures and facilitate learning from failure. Future studies on coping strategies could study the interplay of coping strategies used to resolve challenging social situations that various stakeholders of practicing entrepreneurs impose.

    The nonlinear behaviour of a pantograph current collector suspension1999Ingår i: Proceedings of the 1999 ASME Design Engineering Technical Conferences, 1999Konferensbidrag (Refereegranskat)
    Abstract [en]

    The pantograph-catenary system is a critical component for trains required to run at higher speeds. The pantograph often includes nonlinear characteristics and the scope of this work is to investigate if nonlinear dynamic phenomena can occur in an existing design. A model of a pantograph suspension subsystem has been developed according to physical parameter values of the head suspension of the Schunk WBL88/X2 pantograph, providing electric power to the Swedish high-speed train X2. Studies of the system response for different force excitation show both harmonic, subharmonic and chaotic behaviour for the investigated parameter regions.

    Modelling and simulation of catenary-pantograph interaction2000Ingår i: Vehicle System Dynamics, ISSN 0042-3114, E-ISSN 1744-5159, Vol. 33, nr suppl, s. 490-501Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Modelling and simulation of the dynamic behaviour of catenary-pantograph interaction is an important part when assessing the capability of a current collection system for railway traffic. The large variation in infrastructure characteristics in different countries and railway companies, different types of traffic, designs of pantographs etc. makes it almost impossible to develop a final simulation model of such a system. Instead, it would be favourable to have a tool that has the ability to set up models of such systems, choose relevant detail of the models, run simulations and finally visualize the results. To make the tool useful for engineers, design experts as well as simulation experts, the functionality of the tool must be worked out. Aspects on computer simulation such as developed models, simulation methods and computer tools are presented. The aim is to develop a scenario that considers different designs, models, solution methods and user levels. The scenario focuses on how to structure the use of simulation of dynamics in catenary-pantograph development. A scenario is sketched built on different user levels, a modular structure and a structure for information management

    Retrospective relational sensemaking in R&D offshoring2017Ingår i: Industrial Marketing Management, ISSN 0019-8501, E-ISSN 1873-2062, Vol. 63, s. 205-216Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To address the increasing relational challenges in international R&D collaboration, the present study develops a framework for understanding retrospective relational sensemaking in R&D offshore relationships. Using a comparative case study methodology, this study analyzes relational data from 56 interviews regarding four R&D offshore relationships between two large Swedish multinational companies and four R&D offshore partners. This study contributes to existing sensemaking theory by constructing a framework for retrospective relational sensemaking, including triggers and the phases of enactment, selection, and retention, to improve relational learning in R&D offshore relationships.

    Framtidens Norrbotten: Fem scenariobeskrivningar över länets utveckling2016Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Föreliggande rapport utgör en framåtriktad analys av de regionala förutsättningar som rapporterats inom projektet Regional förnyelse, som finansierats av Länsstyrelsen i Norrbottens län och Luleå tekniska universitet (LTU). Utifrån de studier och rapporter som bidragit till en ökad förståelse kring länets möjligheter och utmaningar resonerar vi i den här studien om möjliga framtidsscenarier för Norrbotten. Vår målsättning är inte att förutspå den regionala utvecklingen utan att i stället lyfta fram ett antal scenarier som det regionala utvecklingsarbetet kan leda till. Syftet blir att skapa ett diskussionsunderlag som kan vara till nytta för framtida utveckling av regionala strategier såsom exempelvis den regionala utvecklingsstrategin och den regionala innovationsstrategin. Regionala strategierDen regionala utvecklingsstrategin ingår i EU:s och Sveriges strategier för hållbar tillväxt och är styrande för de mer operativa programmen i länet. Strategin binder samman planeringsprocesser som har betydelse för en hållbar tillväxt och kan därigenom underlätta samverkan inom och mellan länen. Strategin utgör och ett strategiskt underlag i förhandlingar mellan länet och regeringen och även vid överläggningar på EU-nivå.Den regionala analysen av Norrbottens förutsättningar för utveckling och potential för tillväxt resulterade i fem strategiska områden där ett antal prioriterade åtgärder anges. De största utmaningarna är den demografiska utvecklingen och den framtida kompetensförsörjningen. Avgörande för regionens tillväxt är att det finns arbetskraft och kompetens som matchar arbetslivets behov. Med en allt äldre befolkning ökar försörjningsbördan och det blir allt svårare att upprätthålla välfärden med minskade skatteunderlag.Regionala analyserEtt flertal rapporter och studier har författats inom ramarna för projektet Regional förnyelse. Näringslivsanalyser och analyser av internationell handel stödjer att det finns goda förutsättningar för tillväxt inom länets företag. Företagarna beskriver kompetensförsörjning som en av de största utmaningarna för att uppnå planerad tillväxttakt. Regionala scenarierUtifrån de regionala analyserna har fem scenarier, i form av framtidsbilder, målats upp. Avsikten med scenarierna är att beskriva hur regionala insatser och utveckling kan skapa alternativa framtider för Norrbotten. Avsikten med scenarierna är således inte att förutspå regionens framtida utveckling utan snarare peka på hur olika typer av regional utveckling kan skapa olika förutsättningar. De scenarios som diskuteras i denna rapport är:— Scenario I: Basindustriregionen— Scenario II: Kunskap, kreativitet och kommunikation som regional drivkraft— Scenario III: Förändrat globalt klimat med nya möjligheter— Scenario IV: Smart specialisering baserad på relaterad variation— Scenario V: Diversifiering efter en nationell genomsnittsmodell

    Design investments in small wood manufacturing companies: problems and possibilities of using design expertise in product development2005Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Previous research has shown that effective use of design by small companies can contribute positively to business performance and competitiveness. The Swedish wood manufacturing industry is facing intensified global competition. In many, especially smaller, companies the struggle for their survival involves an imperative to find new ways of development in order to increase profit. Design and product development are traditionally given low priority in many companies, but design investments are now seen as an important opportunity to create competitive advantages for small wood manufacturing companies. Until today, however, very little research has been published addressing product development and design in small wood manufacturing companies. The main purpose of this research was to document how small wood manufacturing companies invest in design and use professional design skills in product development. More specifically the objectives were: to examine how the product development process of a design project is carried out to identify success factors and problems occurring during the project process to compare company managers' and design consultants' perspectives on how they view the problems and opportunities of a design project. The results are presented in three papers based on two multiple case studies of small wood manufacturing companies in Sweden. In the first study, presented in paper A, data was collected from nine wood manufacturing companies located in the county of Norrbotten. Papers B and C were based on the second study, which comprised four small wood manufacturing companies, located in the counties of Norrbotten and Småland, together with their associated design consultants. Data collection methods in both studies involved mainly semi-structured interviews complemented by questionnaires, an approach chosen to achieve both broad and deep understanding of each studied case. The results indicate that using design experts in product development can be of importance for creating a competitive edge for small manufacturers if used efficiently. Design investments cannot be considered a guarantee for success, however, and it should be clear that small wood manufacturers, also ones of similar size and structure, face different needs for design and possess different competence to manage design effectively. Product development processes were seen to depend widely on the existing conditions and hence vary from project to project. No formalized methods were used in the studied design projects and processes were managed more or less on an ad hoc basis. Limited resources concerning finances, personnel and design competence, together with a lack of planning and process structure, were seen to affect the project outcome negatively, whereas previous design experience, management by the designer when a company lacked experience, external financing, and a good relationship and tight communication between the company and the designer were identified as success factors. Differences in project perspective, experience level, and starting points cause managers and designers to take different views on problems and opportunities occurring in a design project and therefore cause communication difficulties and affect project cooperation negatively. It seems that to get these perspectives to meet is a large challenge to achieve successful cooperation.

    An integrated design evaluation system supporting thermal-structural iterations1998Ingår i: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 6, nr 3, s. 179-187Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In the design of high temperature components, design evaluation often requires an iterative procedure between thermal fluid and thermal structural simulations An integrated computer system providing an iterative environment for the multidisciplinary simulations re quired has been developed. The system supports iterations between thermal fluid and thermal structural simulations using two different commercial simulation packages. Traditionally, fluid and structural analysis have been simulated separately and analysis of coupled prob lems has required special, multidisciplinary simulation packages which are seldom used in early stages of design. Improving the infrastruc ture for data exchange between separate computer applications is one way to significantly reduce the lead time for design iterations. This reduction in lead-time allows multidisciplinary effects to be accounted for in early stages of design. The design system is demonstrated on an exhaust manifold, where the thermal interaction between fluid and structure is of significant importance. The commercial simulation tools have been integrated to demonstrate the effect of automised data flow on design methodology, i.e , de sign iterations. This integration method makes use of existing features in the simulation packages and uses an export file format as the neu tral exchange format. In this way, the integrated system is simple and fast to develop which is preferred in small prototype systems and de velopment project Database integration supports a tighter integration, but requires more development effort. For design systems, where several design tools need to communicate, standardised information management procedures are preferable, following the ideas of the STEP framework.

    Overcoming barriers to sustainable product-service systems for non-assembled products: A case study within the renewable energy industry2019Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Purpose – The purpose of this study is to increase knowledge regarding sustainable product-service systems (SPSS) barriers and solutions for non-assembled products. To answer this purpose, we developed the following research questions: (1) what barriers do providers face when utilizing SPSS in a non-assembled product context and (2) what solutions can be used to overcome these barriers?

    Method – This study was conducted as an abductive case study within SPSS in the renewable energy industry. We interviewed a total of 20 respondents from 16 different companies operating in China, Cyprus, and Sweden. Each respondent was chosen based on their experience and knowledge within the area.

    Findings – The findings are summarized in a framework that links the identified barriers with specific solutions. In brief, finding stakeholders for large and long-term investments was identified as a major barrier while educating stakeholders was suggested as a common solution.

    Theoretical and practical implications The results disqualify two of the barriers in the existing literature while suggesting that varying market conditions is a new barrier. Furthermore, the study provides new insights to the existing literature and presents a framework that managers can use to matchmake SPSS-barriers with solutions.

    Limitations and future research – The study is limited to a case study focused on barriers and solutions for SPSS-providers. As a result, future research is suggested to validate the findings in another context and among other stakeholders.

    Road grip test in Arjeplog2008Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The Swedish road administration sees a need to improve the road grip estimation capacity for the Swedish road system. The challenge is to find methods to measure road grip fast and reliable. There where six different system types at the tests in Arjeplog, three continuous, two system measuring road grip through deceleration and one system based on GPS and accelerometers. Two system types used air craft runway tires. The other systems used either studded winter tires or friction winter tires. Test runs where performed and road grip where recorded for three different surface types, old system 2000 ice, polished ice and new system 2000 ice. Weather data was collected during the three days. It is clear that all systems can detect changes in road grip. It is clear that continuous systems hold an information advantage over the sequence oriented systems. For measurements of road grip on winter roads, we recommend that rubber compounds adapted for cold conditions are used, as the resolution of the road grip measurement where better. In extreme condition like on polished ice, studded winter tires increase the road grip significantly.

    A need-based approach to product development2007Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    In manufacturing industry, a developing view of life-cycle commitments has in turn triggered an interest in development processes for incorporated physical artefacts. In fact, this new scenario is an expansion of the core manufacturing business such that not only the manufactured artefact but also its functionality can be contracted for. Thus, an emphasis on development of goods becomes an emphasis on development of goods and services combined - a functional product. Such development process is not straightforward since goods and services might otherwise be developed in distinct ways. A service, for instance, is performed as an activity and is partly co- produced with the user and/or customer. Based on this it can be argued that a service is also oftentimes partly customized in some sense. A core competence within the strand of service development would therefore have to be an understanding of customers needs. In contrast, within the strand of product development a core competence is to transform a market opportunity into an engineered physical product ready to launch. Each of these strands builds on different logics in the development processes. Within a Functional Product Development process an integration of these two worlds - the understanding of needs and the development of a physical product - is expected to support the design of physical artefacts aimed for life-cycle commitments. Embarking from an assumption that an understanding of customers', users' and/or peoples' needs is likely to provide useful insights into Functional Product Development processes, this thesis aims to shed light on input into early phases of product development. Previous studies, presented in the appended papers, indicate that ‘needs' - which people cannot readily articulate - are not fully recognized in product development literature or explicitly managed in industry. Thus, building on the results from these studies, the work in this thesis elaborates essentially on two theoretical knowledge domains, i.e., product development and Needfinding. In Needfinding, a main principle is to look for needs, not for solutions. To do so, the methods to generate customer information are focused on data related to what people actually are striving to achieve when taking actions. Hence, goals, contexts, actions and behaviours matter and are probed for by the Needfinding team. A common approach is a combination of methods relying on observations and interviews. In practice, the way in which the study is undertaken will be context dependent. The search for data should be performed by a multidisciplinary team, in which the idea is that designers should participate. In view of the identified differences it can be concluded that the input from a needs-based approach differs in terms of the kind of data that would result in a need statement. Such an approach provides rich and contextual information about people's activities and goals, while a typical product development approach provides rich and detailed information about the products that customers use. Thus, a need-based approach supports innovative and new products and traditional product development seems to support improvement of existing products. Yet both are important to develop functional products. The challenge of integrating the two stances is identified as related to cultural and historical formative issues. Designers are well acquainted with product improvement from a technical point of view, but needs identification is likely to require a non-trivial shift in perspective and in particular will rely on a broadly sociological ability - the ability to observe human beings.

    Functional product development: an explorative view2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Embodied in the concept of functional products is a shift in view for manufacturing companies as providers of physical artefacts to service providers. Furthermore, differentiation by offering added value, increased commitment towards customers, life-cycle commitment for the physical artefact and close collaboration between manufacturing companies are characteristics of the concept of functional products. On a business level, the concept of functional products are expressed as total offers, integrated solutions and/or functional sales. On a product development level, the integration of hardware, software and service aspects is identified. Accordingly, from one viewpoint the concept of functional products leads to a transition view and from another viewpoint the concept of functional products leads to an integration view. A shift in view and integration seem to be in opposition to each other. The purpose of this thesis is to explore what new approaches in product development are motivated by the concept of functional products. To understand the concept of functional products, the differences between hardware and service aspects have to be understood. A knowledge perspective frames the study. The focus is upon hardware and service knowledge. The work in this thesis approaches the concept of functional products from a product development perspective i.e. a development of physical artefacts viewpoint, bringing in service management literature. The studies are delimited to manufacturing companies acting in a business-to-business environment. The research strategy used encompasses an interpretive approach and qualitative material is generated in both interviews and meetings with industry people. Two perspectives emerge in the theoretical framework, a hardware perspective and a service perspective. A transition or a shift in view from a hardware perspective to a service perspective can take place on a business level, whereas on a product development level an integration view is necessary. The ability to alternate between a service perspective including needs analysis and a hardware perspective including solutions has been presented. Thus, the importance of understanding needs is recognised for functional product development. New approaches for product development are found concerning integration of knowledge, collaboration and reflective approach to services. An open-minded approach to products where new products and offerings can emerge has also been discussed.

    Abstract [en]

    This work is part of a study where a descriptive and a prescriptive approach have been used. This paper deals with the descriptive part and discusses views on decision support in product development to identify factors of relevance to con-sider when designing computer-based decision support for total offers. Providing services in form of physical artefacts offered as ‘functions per unit’ is at the heart of total offers. The intention is to provide customers with functions in time and place ‘as-needed’, based on a life-cycle commitment. This new scenario is found in manufacturing industry in addition to a traditional view on selling hardware and providing aftermarket activities. Total offers gain access to possibilities to ‘design in’ value added characteristics into the physical artefact, e.g., maintenance, moni-toring, training and abilities to upgrade and/or remanufacture. Computer tools is commonly used to supply design teams with information which is relevant, correct and in time to support resolutions, yet to support a GO/NO GO decision for total offers contemporary tools seems to be insufficient. Relevant factors to take into consideration are to support learning and provide the decision makers with insights in a number of plausible ‘what-if’ scenarios to im-prove the solution space.

    Abstract [en]

    Product development processes are commonly represented in sequential models covering the necessary stages from planning to product rollout, while processes to take needs into the development activities show other aspects, namely that understanding needs requires, for a product developer, additional skills. In our curricula for engineering design education we apply some aspects of design thinking to bring together (a) business savvy, in terms of understanding people’s needs as market opportunities, and (b) product development process, in terms of team-based creativity and collaborative skills, with (c) the basic engineering knowledge. This is a demanding aim, much because the approaches, methods and mindsets differ widely from what the students are used to. Hence, in this paper we elaborate on our efforts to educate engineers in design thinking to provide insights into some challenges for engineering design.  Three key challenges are identified, (1) integrative approaches are not straightforwardly implemented, (2) training of ‘soft’ capabilities to provide a change in thinking, and (3) social competence to make use of design thinking.

    Abstract [en]

    In our view, close collaboration in joint work meetings has gained limited attention from universities. Our vision for promoting innovative forms of academia-industry collaboration is to bridging meeting content, goal and physical domains to facilitate the meetings and everyday interactions of creative and innovative teams. This paper provides an outline of how an emerging approach for team innovation encourages a reorganization of research and development work, as well as provides a new rational for the design and use of collaborative work spaces. The opportunity to dedicate a room, i.e., a boiler room, for creative collaborative meetings occurred when our offices was going to be refurbished. The space, i.e., the physical constraints of the room, was given. Structurally, it is a typical squared room, nothing remarkable about that. However, by observing and talking about our own collaboration and meetings a set of needs was identified. For the boiler room these needs was captured in the words static and flexible. On the foundation of these words the boiler room has been furnish. A furniture FocIn-FocOut was designed to guide people into different modes. The rationale for the boiler room has been made visible and thereby, also the notion of place as a cultural phenomena.

    Abstract [en]

    There are three dimensions of sustainability: environmental, economic, and social. One important task is to integrate them so as to identify how more sustainable paths can be identified, assessed, and decided upon. Previous research has identified systems thinking as a key to achieving this. The purpose of the paper is to build on these ideas and to propose an initial framework that demonstrates the potential of incorporating soft systems methodology and a theory of modalities, introducing aspects in addition to environmental, economic, and social ones. Moreover, theoretical exploration shows that understanding different predispositions, or worldviews, are vital to creating shared and purposeful actions. This paper expresses the intentions of a pre-study, and the ideas are far from mature; however, the importance of collaboration in shared and more sustainable actions is the basis for an industry-wide initiative called the Construction Climate Challenge (CCC).

    A quest for knowledge?2011Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Today, a new knowledge economy and more service-based offerings are commonly mentioned as a challenge for manufacturing companies. This challenge addresses the companies’ knowledge base and the traditional engineering expertise areas. The report starts from an assumption that there are differences in how knowledge is managed, as well as differences in the intentions to why it is managed. Based on this assumption, the purpose in the report is two-folded. First, the purpose is to conceptualize different facets of knowledge within a framework of technical product development. Second, the purpose is that the report serves as a trigger for discussions and reflections on existing practices in industrial workshops. So, despite that the report does not provide the “right” answers to these questions; they still guide the work in our research:• What is actually managed in every-day engineering project work?• And, for what purposes?The work accounted for in the report comes from a literature review and our jointefforts in understanding the research area from a theoretical perspective. First general views on knowledge is presented, including its classification in different ways, compared to information and data, as well as its division into tacit and explicit knowledge, or practical skills and theoretical knowledge. Human factors, including how people search for information, is also presented. Then a more explicit focus on technical knowledge is presented, showing the shift from knowledge as an artefact to a social and personal perspective in recent years. This also encompasses discussing the capabilities and knowledge of an engineer. A contribution of this report is the conceptualization of different facets of engineering knowledge; especially the more social aspects of engineering knowledge have been highlighted.

    Place innovation: using design thinking in live cases2016Ingår i: Proceedings of NordDesign 2016 / [ed] Boks, C; Sigurjonsson, J; Steinert, M; Vis, C; Wulvik, A, 2016, Vol. 2, s. 398-317Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper presents a study based on two views, i.e. innovation in teams of non-designers and live case interactions. This means that a diverse set of roles are involved in the innovation activities that originate from real regional situations. The application area relates to design and development of destinations, e.g. regions, tourism and attractive places. This study focuses on two main issues, namely (a) is it possible to make non-designers momentarily become design thinkers, and (b) is it possible to produce ideas and 'out-of-the-box' views in groups consisting of non-designers within a short timeframe? The purpose of this paper is thus to illustrate and explain these issues in order to contribute to a live case platform for collaborative innovation among society, trade and industry, and universities. The empirical data from four workshops, in total engaging 179 participants, shows that there are several challenges related to the efforts to transfer techniques and methods for design thinking and innovation into the heads and hands of non-designers. For example, trade and business can rarely allocate regular working hours for participatory design thinking, so they act based on traditional professional roles. Also, sessions turn into (unproductive) discussions if the participants are not firmly facilitated and encouraged. Bringing in live cases through the participation of mixed teams places additional requirements on innovation research in respect of implementation and packaging for practical uses.

    Abstract [en]

    Regional research project are, as is also regional industry, highly need-based. That is, understanding the stakeholders' (or customers') real challenges and related needs is important. This study is based on interviews with SMEs in the Northern parts of Finland, Norway and Sweden, but also on available innovation agendas and strategies for each country. The differences among the companies in those regions bring forward distinct needs, while many experience similar challenges, for example low population density, long distances and a high dependency on basic industries. Innovation is identified as a key driver of regional growth and competitiveness. SMEs rarely employ the term innovation to describe their activities, but rather stress 'knowing the customer' as important. This indicates one of the challenges to implement innovation strategy as a driver for growth and competitiveness

    Abstract [en]

    A new vision in manufacturing is to develop product-service integrated value solutions. Today, few firms have fully realized this vision because they are not able to support the reasoning in the early stages of design. The purpose of this paper is to discuss engineers' cognitive challenge when replacing the core product rationale with value logic. The paper problematizes engineering design by dividing knowledge into the categories technically constructed (explicit) and socially constructed (tacit). In doing so, this study contributes the assumed effects of a perspective shift that could guide the development of computational tools.

    Innovation is vital to companies, but also difficult to perform since there are many ways to approach the subject. Typically, a balance between all issues related to innovation is suggested in literature. The empirical study presented in this paper elaborates on two strategies for innovation projects, namely to exploit existing solutions and to explore a market to develop breakthrough solutions. This is done for the purpose to discuss management implications, and thereby also make those transparent for innovation projects. The result indicates that managerial implications for radical innovation projects are to provide internal legitimacy for the projects intentions, to provide for a clear view of balancing aspects by using concepts that fit into opposite ends on a continuum, and to preserve a rich information base about users.

    A service perspective on product development: towards functional products2005Ingår i: Proceedings of 12th International Product Development Conference: IPDM, 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    Functional products are understood as a combination of hardware, software and services. Based on interviews with employees in manufacturing firms the notion of functional product development is described. The purpose has been to explore the differences between a service perspective and a core product perspective and highlight changes in the management of product development processes that are motivated by the notion of functional products. Exploring the differences between the two perspectives has identified a gap of how the product is viewed at the business level and technical development levels. The integration of services into the hardware development process in the form of a customised product or product life cycle has been highlighted. Internal and external communication about needs has been identified as useful.

    Abstract [en]

    The adaptation of Product/Service-System calls for new development models. On one side this businesses give the manufacturing firm possibilities to redesign, upgrade and replace the discrete device that provides the performance their customers are asking for. On the other side, this new situation has to address aspects that are normally not addressed in early product development, i.e., services. In this chapter, we will elaborate on product and service development processes models, as well as system models to propose a frame of reference for multiple perspectives on PSS development. These perspectives are people, product and process. Also, this chapter puts forward implications for the development of PSS models.

    Abstract [en]

    Product-Service Systems (PSS) has now for more than a decade been a research interest in Europe and Japan. The research aims to support manufacturing industries’ ability to provide value in terms of a service offer to its customers, simultaneously taking a more holistic approach to eco-sustainability. The idea of providing customer benefits in parallel with robust products is not new, yet equipping engineers to integrate a radical innovation and service perspective in the early design stages is received as fairly radical. Prevailing methods, tools and design thinking are barriers that prevents approaching PSS by the necessary integration of several, but distinct, logics.Due to the inclusion of both product development and service development in development of PSS, at least, two schools of thoughts exist within the research field of PSS development. Namely, one based on product development rationality and one based on service provision reasoning. In general, such a situation would be a base for a conflict where the debate focuses, which strand that should be more valid than the other. However, if so, this would certainly not benefit the need for cross-disciplinarily research of PSS. The purpose in this paper is two-fold; first, to describe PSS research efforts by acknowledging both the product and the service perspective, second to explore and discuss future directions and by that identify “white spots” on the map which may be seen as relevant to bridge the integration gap.

    Abstract [en]

    The extension of businesses to incorporate the provision of function as a service in supplement to standalone products is an ongoing movement in manufacturing industry. In short, this means that the development intent should be guided by the need of ‘performance in use’ that the customer wants, e.g. thrust rather than an engine. By this, the established knowledge base challenges the development team.This paper embarks from the assumption that there are three main challenges, i.e. (1) innovation activities, (2) customer data acquisition and (3) the transformation of data into design information. The purpose is to discuss knowledge sharing activities to contribute to product-service innovation. In this study it has been found that contemporary data acquisition activities filter out important dimensions of knowledge. Thus, does not provide a sound base for service provisions.

    Abstract [en]

    “Listen closely to your customers, and you are more likely to design products that actually meet or even exceed their needs.”: Such statements have come to dominate company innovation strategies in the last decade, but in reality involving customers in product development is not as straightforward as it sounds. Customers, it is becoming clear, cannot always express their needs adequately. Especially, in the case of innovative products where the starting position by definition includes no existing solution, applying a user-orientated approach is paramount. We argue that techniques for ‘needfinding’ must be the point of departure. This has importance both in terms of methodological issues – how to find customer needs? – and for organizational work – who should be engaged in finding customer needs? In our view, engineers must be involved in identifying and understanding those needs. We have learnt through a series of studies, that structured needfinding by engineers during the earliest phases of product development could better support the process of identifying needs and thereby guide design projects. In this way, two basic problems are overcome. Firstly, identifying needs which are otherwise difficult to articulate becomes possible. Secondly, translation difficulties between customers and engineers are eradicated

    Need driven product development in team-based projects2007Ingår i: Design for society: knowledge, innovation and sustainability ; ICED '07 - Paris, 16th International Conference on Engineering Design ; 28 - 30 August 2007, Paris, France ; conference proceedings, Paris, 2007Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, practical activities of needfinding - an intertwined approach to identifying needs and to visualizing idea concepts in early design - are described and discussed. This is done primarily to gain an increased understanding of the various representations of user needs that are fed into the fuzzy front-end activities of team-based product innovation projects. The empirical basis comes from a study of an eight-month collaborative product development project, performed under realistic conditions by MSc students in close collaboration with their client.Focusing closely on customers and their needs is encouraged within the conceptual framework of Integrated Product Development and is increasingly highlighted as a key enabler in the design of truly innovative products. Despite the fact that identified customer needs are considered as the initial and primary input into such an innovation process, it can be argued that the design teams do not commonly have a sufficient understanding of customer needs and they do not normally interact with customers in their environment. Besides focusing on measurable aspects of user behaviour and requirements, a traditional approach to identifying and managing customer needs usually includes several interpretive stages before being handed over to the design team. In the context of innovative products, the identification and definition of customers and their needs is a non-trivial and difficult exercise. It involves, we suggest, not only needfinding but also the definition of ‘those who might need the product’, users and customers to co-evolve iteratively in the early phases of design.

    Functional product innovation: reaping the benefits of simulation driven design2007Ingår i: Knowledge Sharing and Collaborative Engineering: Proceedings of Fourth IASTED International Conference on Knowledge Sharing and Collaborative Engineering, KSCE 2006 / [ed] M.

    Abstract [en]

    Despite a tradition in selling and developing physical artefacts while viewing services as add-ons, the view on products in Swedish industry extends to include total offers, i.e., service provision. The service providing companies take extended long-term responsibilities regarding the physical artefact and the agreed upon functions. The changed business scenario affects product development, in particular the early phases. A life-cycle perspective, cross-company collaboration and customer needs are issues to take into consideration early on in product development. An extended enterprise business model is presented in this paper to give a notion of the changed input for product development. This is done for the purpose of discussing a simulation driven design approach in relation to a vision for functional product innovation. In an engineering design environment, computational support is commonly used to provide a basis for decisions in product development. In this paper we suggest a new, and additional, way to think about design and to use simulations. We suggest that simulations should be used to drive, and not only verify, the design of a product, and thereby also nurture innovations.

    Engineering design research methodologies in Product-Service Systems: when the complex gets tough2017Ingår i: The 21th International Conference on Engineering Design (ICED17): 21-25 August 2017, University of British Columbia, Vancouver, Canada : proceedings of ICED17 / [ed] Kim H.,Kokkolaras M.,Fadel G.,Van der Loos M.,Skec S.,Oehmen J.,Maier A.M.,Salustri F., The Design Society, 2017, Vol. 3, s. 351-258Konferensbidrag (Refereegranskat)
    Abstract [en]

    The research field of Product-Service Systems (PSS) emerged within the engineering design field to address sustainability and radically lower environmental impact from production and product use stages. PSS research has progressed insights of the industrial phenomena, but are often grounded in either product or service development, and the sustainability perspective had diminished over time. The deviation from what was intended might depend on research methodologies that do not meet the requirements of PSS multidisciplinary research. Some reflections of our research and craftsmanship are thus needed, which is also the purpose of this paper. PSS are used in the paper as a framework to highlight some of the facets of engineering design research activities. The paper suggests that multidisciplinary research has to manage different methodologies and different theories, this can be achieved if underlying assumptions are made transparent and if contradictions between those and the conclusions are discussed. Finally, the paper make an effort to encourage discussions about research methodologies to improve not only research but also implementation in industry.

    Abstract [sv]

    De tre delarna i hållbarhetsperspektivet, dvs. ekologiska, ekonomiska och sociala, bör ses som en integrerad helhet, men det är också det som är utmaningen. Projektet söker undersöka och exemplifiera olika intressenters perspektiv och därmed den kunskapsbas de tar med sig in i en produktutvecklingsprocess. Projektet syftar till att demonstrera hur olika intressenters värden stödjer eller inte stödjer en hållbar utveckling.

    Knowledge exchange challenges within the extended enterprise2005Ingår i: 15th International Conference on Engineering Design - ICED 05: 15 - 28 August 2005 / [ed] Andrew Samuel; William Lewis, barton: Institution of Engineers, Australia , 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    The notion of functional products changes the existing relationship between manufacturing companies. The integration of hardware, software and services in functional products calls for close collaboration with companies having complementary skills. When employees from different companies are involved, strategic resources such as knowledge are shared. From an engineering design perspective, knowledge sharing supported by software systems are useful, though it seems like functional product development insists on integrating multifunctional skills and this is likely to affect the design of software systems. The objective in this paper is to explore knowledge sharing challenges between manufacturing companies, striving to create close functional product collaboration, and hence understand aspects in the design of software systems. In this paper the focus is on Knowledge Based Engineering (KBE) systems, these are considered to be internal engineering specific tools, while collaboration and need for knowledge sharing calls for coupled KBE systems between partners. In this context, knowledge sharing challenges within the extended enterprise are recognised to issues about who to trust and what and how to share. This affects how tightly coupled KBE systems can be. In general, this paper contributes to the ongoing discussion concerning collaboration issues in concurrent engineering design, but especially to the overall understanding of what new demands on KBE systems that are motivated by functional product collaboration.
