    Living lab: An open and user-centric design approach2010Ingår i: Information and communication technologies, society and human beings: theory and framework, Hershey, PA: Information Science Reference, 2010, s. 190-207Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    In this chapter we focus on a new research area, Living Lab that introduces new ways of managing innovation processes. A Living Lab can be viewed as both an innovation milieu and an innovation approach, and the aim of this chapter is to clarify these two perspectives, as well as to illustrate how they can enrich each other. This is done by presenting one Living Lab milieu, Botnia Living Lab, and its key components; and one Living Lab approach, FormIT, and its key principles. The presentation is done on two levels, one general level and one case specific level. The case focuses on involving citizens in the design of an e-service aimed to increase their influence in a municipality and its development. Through this we learnt that the key components of a Living Lab constitutes important structures that enhance the process and as such the principles

    The elusive nature of user needs in existing information systems literature2007Ingår i: Information Management in the Networked Economy - Issues and Solutions: Proceedings of 8th IBIMA Conference / [ed] Khalid Soliman, International Business Information Management Association (IBIMA), 2007Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper, we present a new approach to facilitate the process of eliciting user needs in the information systems development context. Today is has become important to study users and their needs since products or services that contribute to fulfill an unsatisfied need have a high probability to succeed on the market. Hence, identifying and designing for user needs is imperative in innovation projects. We have identified two missing issues within the existing literature concerning user needs and systems development. Firstly, there are no consistent frameworks or categorizations of different types of needs, and secondly, there are no descriptions of how to proceed in the process of eliciting and analyzing user needs. Hence, the purpose of this paper is to present a theory of human motivation and behavior which we use as a framework to elicit and understand user needs. We have found different strengths with this framework such as the facilitation for the analyst to find divergent views of the same need and as well as needs that were solutions to another need. In addition, divergent views of the same need became obvious when we applied this framework. A drawback we have observed by using the framework is the possibility that a need is forced into a box, thereby risking missing its actual meaning.

    User expressions translated into requirements2010Ingår i: Human Technology, ISSN 1795-6889, E-ISSN 1795-6889, Vol. 6, nr 2, s. 212-229Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Grounding the development of mobile and ubiquitous services on actual needs and behaviors of users, rather than on designers intuition, is a well established tradition today. However, gathering data about users in different contexts usually result in large amounts of data that have to be analyzed and translated into requirements. This is a crucial process in the development cycle and its outcome is usually very dependent on the preconceptions of the developers or researchers. Despite this strong element of subjective influence the translation process is seldom made transparent. Nor are the user needs related to psychological discussions and existing taxonomies. The aim of this paper is, therefore, to contribute to the field by presenting a process for translating user expressions to needs and later to requirements using Reiss taxonomy of human needs as a theoretical base. Using this translation process we were able to identify two hierarchical levels of needs: needs of a service and needs in the service. The process also made it possible for us to see needs hidden in general expressions and to reformulate them accordingly. Further, it generated a clear traceability from user expressions to requirements, and finally, confirmed the importance of focusing on, and understanding, the situated needs of users.

    Analyzing Product-Service Systems conceptual design: the effect of color-coded 3D representation2013Ingår i: Design Studies, ISSN 0142-694X, E-ISSN 1872-6909, Vol. 34, nr 6, s. 763-793Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The paper presents the testing activity of a color-coded 3D visualization approach, developed to enhance the designers’ awareness during the conceptual design of a Product Service System (PSS). Protocol analysis is applied to eight design sessions to compare the behavior of different design teams when featuring printouts of color-coded CAD models, instead of spreadsheets with numerical tables, as carrier of value-related information. The analysis focuses on the time spent on the different activities during the sessions, highlighting the problem solving strategies and the consideration of PSS related aspects. The analysis shows that design teams featuring printouts of color-coded CAD models made a more extensive use of information during problem analysis, following a more structured design process, than teams using spreadsheets.

    Value assessment capabilities in early PSS development: a study in the aerospace industry2012Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Providing added value to standalone products by adding services is at the core of product service systems (PSS) offered in manufacturing industries. Providing PSS requires a change not only in the way products are sold, but also in the way they are designed and developed. Engineers need to assess the value of a forthcoming PSS solution as soon as possible in the design process, addressing service-related issues that often fall outside their technical horizon and are challenging to seamlessly translate into the product technical requirements. The aim of the thesis is to investigate the early stages of aerospace product development, proposing methods and tools in order to improve the decision-making process, by enhancing the awareness of engineers and designers about the value contribution of different design alternatives. This academic work was performed through action research in close collaboration with major European aerospace manufacturers, research centers, and academic institutions conducting research in product development. The thesis first depicts the current practices and limitations of value assessment in early design stages, describing the increasing complexity of the aerospace development projects. Improvements for current practices are proposed in terms of developing value assessment capabilities coupled with requirements analysis and enhancing communication of the expected value contribution of a forthcoming solution.Second, this thesis proposes a conceptual approach aiming to enhance the communication between engineers and designers of the value-related aspects of a solution in early design stages. This approach allows for the visualization of the results of a value assessment activity using color-coded features on the product computer aided design (CAD) model. The characteristic of the approach is to allow for the simultaneous visualization of value scores and knowledge maturity in a unique representation. The approach is meant to increase the awareness about the multifaceted aspects of the value assessment of different designs, promoting tradeoff and impact analysis.In conclusion the thesis summarizes the findings of the empirical analysis, showing the need to complement requirements information with the assessment of value and knowledge maturity, and proposing color coded CAD models as technological enabler for the communication of the outcomes of the value assessment. Finally guidelines for future research are provided.

    Value Driven Design: a methodology for value-oriented decision making in preliminary design2013Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Making design decisions during preliminary design of a complex product, such as an aircraft, is a difficult activity. Numerous teams, acting on a global scale, take part in such design activities, approaching the problem from different perspectives and at different levels of granularity. Based on their position in the supply chain, design teams can focus either on the product as a whole, on its service-related aspects, or on the design of specific components of the product itself. The complexity of the design causes design teams to often base decisions on flawed or incomplete information, since stakeholders’ needs and perceptions are difficult to predict and communicate among teams. Such situations make it problematic for the developers to understand which design concept would be the most valuable to develop.Through collaboration with major European aerospace manufacturers, this research has highlighted the limits of current product development practices in addressing the promotion of more value-oriented design decisions in preliminary design This thesis has investigated the meaning of value in preliminary design decision-making and proposed a way forward towards its assessment and communication, introducing a value-oriented perspective to decision-making. This thesis builds on the Value Driven Design (VDD) concept increasingly discussed in the aerospace industry. VDD, in its original formulation, promotes the use of the mathematical optimization of a value function to select the most valuable design concepts. VDD is debated in literature, and an established VDD theory is not present. Contributing to such debate, this thesis proposes a Value Driven Design methodology for decision making in preliminary design that goes beyond the concept of mathematical optimization of a single value function. It considers the value of a design concept as encompassing stakeholders’ needs that are not always quantitatively quantifiable in a mathematical function, giving up with the idea of obtaining an absolute numerical measurement for value. The methodology takes the standpoint of an aircraft sub-system manufacturer. It merges concepts available in literature (i.e. Value Creation Strategy, Knowledge Maturity, Customer-Oriented Design Analysis) with the approaches developed from the findings of the empirical study. The methodology is based on correlating value aspects at different supply chain levels, assessing the maturity of the knowledge and computing the value of a design alternative compared to a baseline and a target. The use of colored features in CAD models to enhance the communication of value-related information is also proposed, and preliminary tested.Finally, guidelines for value assessment and visualization in preliminary design are provided, and the contributions to the VDD field are discussed together with the industrial implications of the methodology.

    Assessing the value of product service systems alternatives: a conceptual framework2011Ingår i: Design Principles and Practices: An International Journal, ISSN 1833-1874, Vol. 5, nr 5, s. 655-672Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The paper proposes a conceptual framework, linking value-oriented criteria, simulation approaches and knowledge sources, to support the value-driven assessment of Product/Service Systems in the preliminary product development phase. The paper describes the peculiarities of the Multi Attribute Decision Making (MADM) problem in the PSS domain, identifying relevant categories of criteria to guide the preliminary value assessment of Product/Service Systems. Each criteria has been analyzed and linked to the appropriate simulation method, and each method has been further associated to people/roles in the Virtual Enterprise who might possess relevant knowledge to populate the models. The value assessment of an aircraft engine component has been used as case study for the definition of the value attributes. The list of generic value-related criteria, coupled with the respective simulation approaches has to be considered the main result of the paper.

    Effectiveness of colour-coded CAD models value visualisation in PSS conceptual design2013Ingår i: Product-Service Integration for Sustainable Solutions: Proceedings of the 5th CIRP International Conference on Industrial Product-Service Systems, Bochum, Germany, March 14th - 15th, 2013 / [ed] Horst Meier, Berlin: Springer Science+Business Media B.V., 2013, s. 495-506Konferensbidrag (Refereegranskat)
    Abstract [en]

    During the 3rd CIRP IPS2 conference an approach toward communicating the value contribution of different PSS design alternatives using colour-coded CAD models was presented. Building on this work, the paper presents and discusses the results of the testing activity undertaken to verify the effectiveness of the colour-coding approach. The paper describes the setting and the findings of a series of PSS Design Experiments involving 8 design teams composed by master students in product development. Through the application of protocol analysis to the recorded design sessions, the paper compares the behavior of the design teams when using colour-coded CAD models, instead of QFD-like numerical tables, for value communication in PSS conceptual design.

    Abstract [en]

    The paper proposes an approach to increase the decision makers’ awareness at the gate, when evaluating PSS design alternatives from a lifecycle and value oriented perspective. The paper illustrates a lightweight value visualization tool, running on top of existing CAD systems, supporting value visualization of a given part or assembly, thanks to color coding. Information from value assessment is in this way translated into visual features of the CAD 3D model. Despite the approach is still on a start-up phase, an early mock-up of the tool has been developed and applied to a real aircraft engine component, in order to verify the feasibility of the approach.

    Value visualization in product service systems preliminary design2013Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 53, s. 103-117Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Emerging from a study in the European aerospace industry, this paper identifies a gap in the way value-related information is communicated to designers of hardware in the preliminary stages of Product Service System (PSS) design. To fit this gap a Lifecycle Value Representation Approach, named LiVReA, that uses color-coded 3D CAD models to enable value information to be translated into visual features, is presented. Such approach aims at enhancing designers’ awareness of the value contribution of an early design concept on the overall PSS offer by complementing requirements-based information with criteria reflecting the fulfillment of customers and system value. The paper details the development of the approach, its underlying rationale, the results of preliminary validation activities and the potential for industrial application in the light of the currently available PSS representation tools.

    Enhancing intra-cognitive communication in product design with color-coded CAD models: a visualization approach2012Ingår i: Proceedings of the 3rd IEEE International Conference on Cognitive Infocommunications: CogInfoCom 2012, Piscataway, NJ: IEEE Communications Society, 2012, s. 487-492Konferensbidrag (Refereegranskat)
    Abstract [en]

    Empirical investigation in the European aerospace industry has shown major drawbacks in the way design teams share information about the value contribution of a solution during early design stages. Across functions and organizations, design teams collaborate mainly using the contractual requirements as a basis, lacking of recording and communicating the contextual knowledge and the overall intent of product and service development projects. The paper proposes an approach that uses color-coded 3D CAD models for intra-cognitive communication of such value-related information to enhance the decision-making process in design. The paper first introduces the concept of product service systems and the benefits provided by visualization, afterwards it describes how value visualization can be implemented in a CAD 3D environment. A case study derived from the aerospace industry is presented to provide an example of application of the approach in a real industrial environment.

    Assessing the value of sub-system technologies including life cycle alternatives2011Ingår i: Glocalized Solutions for Sustainability in Manufacturing: Proceedings of the 18th CIRP International Conference on Life Cycle Engineering, 2011, s. 669-674Konferensbidrag (Refereegranskat)
    Abstract [en]

    Emerging from an industrial case study in the aerospace industry, the paper proposes an approach to evaluate subsystem technology concepts from a life cycle perspective. The approach is composed by 5 main phases that aims to drive product designers towards more value-oriented design decisions. It is shown how different life cycle alternatives, such as the selling of a Product-Service- System instead of a traditional product, deeply impact the value of design alternatives. The described approach has been developed in collaboration with industrial partners and represents a potential instrument to enhance value-driven product design.

    Using 3D CAD models for value visualization: an approach with SIEMENS NX HD3D Visual Reporting2014Ingår i: Computer-Aided Design and Applications, ISSN 1686-4360, Vol. 11, nr 3, s. 284-294Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Recent literature in Systems Engineering has suggested the use of “value” to drive decision-making activities during preliminary design. Here the choice of a technology for a system/component is often oriented by the outcomes of a value analysis. However, to correctly evaluate design trade-offs, a visual link has to be established between these results and the product requirements/geometry. The paper proposes the use of color-coded 3D CAD models to support the visualization of value analysis results in a Stage-Gate® process. The approach has been developed and exemplified within a case study related to the design of an aero-engine component, and has been demonstrated using SIEMENS NX HD3D Visual Reporting. Eventually, the paper presents the results of verification activities conducted in academia.

    Value-oriented concept selection in aero-engine sub-systems design: the EVOKE approach2013Ingår i: 23rd Annual International Symposium of the International Council on Systems Engineering, INCOSE 2013: Philadelphia, PA, 24-27 June 2013, 2013, Vol. 2, s. 977-991Konferensbidrag (Refereegranskat)
    Abstract [en]

    The design of complex systems requires detailed analysis to be moved earlier in the design process. Value Driven Design methodologies extend the Requirements Management and Systems Engineering processes to reduce time and costs needed to identify the right solution direction to be pursued in detailed design. Emerging from the findings of an EU FP7 research project, the paper describes an approach for preliminary concept selection, named EVOKE, that uses value as a basis for decision. EVOKE enables quick value analysis to be executed by component manufacturers by taking as input a set of value dimensions and drivers communicated by the system integrators, together with information about the high-level engineering characteristics of the sub-systems under consideration. The approach and its technological enablers are described in detail through the use of a case study related to the design of new intermediate compressor case for turbofan engines.

    Abstract [en]

    The development of complex products, characterized by long lifecycles and deep supply chains, requires enhanced capabilities to assess, in an early design stage, the value of a solution not merely from a requirement fulfillment perspective. The paper proposes a conceptual scenario, described in terms of activities, inputs, outputs, actors and mechanisms, which details how aircraft components can be developed and assessed with a focus on their value contribution at system level. The scenario proposes a set of methodological and technological tools needed to enable value assessment in preliminary design, and has been created and preliminary validated together with major European aerospace manufacturers. The importance of being able to communicate the lifecycle value contribution of design solutions during the development work emerged clearly from the study. In this spirit, an approach to visualize such contribution directly in a 3D CAD model (across a set of value criteria, dimensions and drivers) has been proposed and it is currently under development.

    PLM paradigm: how to lead BPR within product development field2009Ingår i: Computers in industry (Print), ISSN 0166-3615, E-ISSN 1872-6194, Vol. 60, nr 7, s. 476-484Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The design and implementation of a PLM solution in a cross-company environment is a complex and labour intensive operation, which is often coupled with a Business Process Re-engineering (BPR) project to better deploy technologies as well as methodologies and to target the system implementation on the real company needs. Enterprise Modelling (EM) languages are typically used to collect and share process knowledge among the BPR participants. Plenty of techniques are actually available at this scope and it is not always easy to understand how to select and use them in the different steps of re-engineering. The main purpose of this paper is to perform a qualitative analysis of three well known EM languages (IDEF, UML and ARIS) and to propose a new methodology, based on their integrated use, supporting BPR efforts in the Product Development domain.

In order to check, before embarking on a full-scale implementation, if the system will satisfy initial expectations, physical prototypes (Pilots) have to be tested in a near real usage environment to obtain qualitative and quantitative information for the final tuning activity. This paper proposes a methodology to guide this Pilot specifications definition process. The main aim of the roadmap proposed is to support the KMS design team in configuring a Pilot solution able to provide valid feedbacks of final system behaviour both from a software and non-software point of view.On one side the methodology guides the definition of Pilot implementation specifications from a technical perspective. It helps engineers and knowledge experts in selecting, refining, merging and cascading down the initial heterogeneous Pilot high level objectives to a lower level, and in elaborating a functional description of the KMS prototype. It proposes, moreover, a structured framework to classify KMS' performance indicators to help the Pilot task force in properly carry out the validation task.The methodology, on the other side, pushes the design team in considering those behavioural and methodological issues that arise from the necessary change in work practice as a result of implementing the KMS within a Virtual design environment. In parallel with the definition of technical specifications, the roadmap supports knowledge experts in developing and testing a set of Knowledge Management guidelines, intended as a list of Best Practices and Lesson Learned aiming to help users in utilizing the potentialities of the new solution.The methodology has been developed within the European project VIVACE to support the design and implementation of a new KEE system in the aeronautical domain.

    Social technologies for cross-functional product development: SWOT analysis and implications2012Ingår i: 45th Hawaii International Conference on System Science (HICSS), Los Alamos, Calif.: IEEE Communications Society, 2012, s. 3918-3927Konferensbidrag (Refereegranskat)
    Abstract [en]

    Innovation is triggered by the cross-pollination of fields and disciplines. In product development, this means bringing together people with different expertise to develop breakthrough product and service offers. In spite of their great potential, cross-functional efforts are not yet adequately supported from a knowledge perspective, asking for a more open and bottom-up open approach to knowledge management. The paper aims to investigate how social technologies can enhance collaboration and knowledge sharing in complex, cross-functional and cross-organizational product development projects. It initially highlights the role of weak ties as enablers for more innovative design processes, especially when manufacturing companies move towards developing integrated offers mixing hardware, software and services. Emerging from data collected in two case studies conducted within the European aeronautical industry, it applies the Strength-Weaknesses-Opportunities-Threats (SWOT) framework to highlight how tools such as wikis, blogs, forum and microblogs can shorten and increase the quality of early design decisions. Furthermore it elaborates on how the design team can enhance its perception of the needs to be addressed and leverage its capability to develop solutions for the task at hand.

    Criteria for assessing the value of Product Service System design alternatives: an aerospace investigation2011Ingår i: Functional thinking for value creation: Proceedings of the 3rd CIRP International Conference on Industrial Product Service Systems / [ed] Jürgen Hesselbach; Christoph Herrmann, Springer Science+Business Media B.V., 2011, s. 141-146Konferensbidrag (Refereegranskat)
    Abstract [en]

    Growing from data collected within a major EU research project in the aerospace domain, the paper proposes a candidate approach to assess the value of Product Service System design alternatives in a preliminary design phase. A framework composed of six main families of value criteria is proposed to support the product/service development team in evaluating the responsiveness and trade-off between alternative designs that target lifecycle commitment, withrespect to the impact on perceived values and stated needs and expectations. A visualization approach is also proposed to quickly communicate the value contribution of the design alternatives at the decision gate.

    Introducing PSS thinking in product-based organizations: a case study in the Swedish manufacturing industry2010Ingår i: Industrial product-service systems (IPS²): proceedings of the 2nd CIRP IPS² Conference [2010, Linköping, 14-15 April] / [ed] Tomohiko Sakao, Linköping: Linköping University Electronic Press, 2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    For traditional product-based companies PSSs represent a huge jump in the dark. Thus the introduction of PSS-like features, aiming to extend the artefact-based offering, is done gradually in the earliest stages, focusing on some value-adding aspects while excluding others. The main aim of this paper is to understand how the transition to PSS is initiated from a company perspective and how these PSS embryos are supported in everyday design activities. The authors have conducted a case study in the Swedish manufacturing industry to collect issues, challenges and opportunities related to the development of service-based offering in their early beginning. As a result they introduce the concept of knowledge-intensive products, seen as an intermediate step towards the full integration of products, software and services, and discuss their implication from a product development point of view.

    Needs and requirements: how TRIZ may be applied in product-service development2009Ingår i: Proceedings of the 2nd Nordic Conference on Product Lifecycle Management - NordPLM'09 / [ed] Johan Malmqvist; Göran Gustafsson, Göteborg: Chalmers tekniska högskola.

    Abstract [en]

    In Product-Service Systems development, understanding of the customers' use of goods seems vital, since the product per se is not sold but rather the performance it brings to the customers' processes in terms of added value. This changed business scenario insists on an integration of a service and a product perspectives in early design phases. However, the approaches to understand customers diverge. In this paper, a need matrix, from the economic theory of needs, and a requirement matrix, from the TRIZ methodology, are used to elaborate on integration aspects to understand customer statements. The comparison of these matrixes made the distinct logics apparent, and gave an indication for the necessity of another type of specification for PSS products. Also, the knowledge base for PSS methodologies has to be extended to encompass a part that visualizes non measurable aspects such as needs.

    Abstract [en]

    The emerging industrial business partnerships, which feature cross-functional and cross-company development efforts, raise the barrier for the establishment of effective knowledge sharing practices in the larger organization. This chapter aims to highlight the role of knowledge as a key enabler for effective engineering activities in the light of such emerging enterprise collaboration models. Knowledge Enabled Engineering (KEE) is presented as an approach to enhance the extended organization’s capability to establish effective collaboration among its parts, in spite of different organizational structures, technologies or processes. KEE is analysed in its constituent parts, highlighting areas, methods and tools that are particularly interesting for leveraging companies’ knowledge sharing capabilities.

    Abstract [en]

    This paper analyzes the knowledge sharing process that characterizes Product Service Systems (PSS) design, drawing on data from an in-depth study in the Swedish manufacturing industry. It categorizes and describes the most relevant knowledge sharing barriers affecting early PSS development phases, discussing them in terms of capabilities to be included in a knowledge engineering system to fulfil the increasing need for knowledge in product-service design. To cope with these barriers, the authors introduce the concept of Engineering 2.0, which borrows the general Web 2.0 concept and translates it into engineering terms, going into the details of how functional product development may benefit from the possibility to integrate bottom-up and "lightweight" knowledge sharing techniques with traditional PLM/PDM/CAD solutions, and highlighting the most relevant challenges for the Engineering 2.0 research.

    Engineering 2.0: an approach to support cross-functional teams in overcoming the knowledge sharing barriers in PSS design2011Ingår i: International Journal of Product Development, ISSN 1477-9056, E-ISSN 1741-8178, Vol. 15, nr 1/2/3, s. 115-134Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The paper discusses the key enabling mechanisms introduced byWeb 2.0 technologies that can support Product Service Systems (PSSs)development teams in increasing the quality of early design decisions.The paper collects success stories and lessons learned from two empirical casestudies in the aeronautical supply chain, and from a set of questionnairesforwarded to major automotive manufacturers, about the implementation ofEngineering 2.0 tools, such as wikis, blogs and forums, to overcomeknowledge-sharing barriers between cross-functional design teams. The studyreveals that bottom-up and lightweight technologies can enable theimplementation of more value-driven development processes, providing meansfor locating expertise in the extended organisation, for capturing the ‘context’of the information managed, and for assessing and validating knowledge assetsin a more collaborative fashion. Eventually, it points to the most relevant issuesthat currently prevent the implementation of Web 2.0 technologies in a productdevelopment setting.

    Abstract [en]

    The aim of the paper is to discuss the rising potential of social software to increase the knowledge management capabilities of virtual product development teams. It presents six fundamental transitions, elaborated from the empirical findings, which justify the rise of a more bottom-up, social creation and sharing of engineering knowledge in the virtual organisation. The study suggests that traditional engineering knowledge management approaches alone are not sufficient to support development activities in the virtual organisation, and that such teams display an increasing demand for social, comparatively lightweight and remixable platforms for bottom-up, social creation and sharing of knowledge.

    Abstract [en]

    In Product Service Systems development, understanding the customer use of goods is vital, since the product per se is not sold but rather the performance it brings to the purchaser in terms of added value. Moving away from offering just a product or service to become a provider of "integrated solutions" implies inevitable changes in the interaction with the customer as well as in the way knowledge is managed and shared in the cross company environment. The main aim of this paper is, on one hand, to provide examples of how Product-Service Systems raise the demand on such cross-functional knowledge sharing; on the other hand it aims to point out a set of requirements for the successful development of Knowledge Enabled Engineering systems able to support a PSS paradigm in a Virtual Enterprise context.

    Brand equity in the professional service context: Analyzing the impact of employee role behavior and customer–employee rapport2011Ingår i: Industrial Marketing Management, ISSN 0019-8501, E-ISSN 1873-2062, Vol. 40, nr 7, s. 1093-1102Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The study examines whether factors related to customers' perception of employees' behavior in terms of customer perceived role ambiguity, role overload and customer–employee rapport influence the development of brand equity in the professional service context. 632 customers of one of the Big Four auditing companies participated in the study. The results of structural equation modeling show negative effects of role ambiguity and role overload on brand associations, perceived quality and brand loyalty, which constitute brand equity. The findings indicate a positive effect of customer–employee rapport on the enhancement of B2B brand equity. However, the negative influences of role ambiguity and role overload on customer–employee rapport transfer detrimental indirect effects on brand equity. The study contributes to an understanding of how the real interaction between service providers and customers can influence brand equity in the professional service setting.

    Abstract [en]

    The main purpose of this study is to investigate the effects of buyer-seller interdependencies on the formation of brand equity in the B2B context. The study demonstrates that a higher level of dependency, experienced by the multi-services buyers compared to the uniservice buyers, affects overall brand equity developed towards the seller. By considering the hierarchy of effects between the brand equity dimensions, the study shows that the factors capturing the interdependencies have a significant impact on brand loyalty of the multiservice buyers. The study contributes to branding research by evaluating the impact of buyer-seller dependency on B2B brand equity.

    Abstract [en]

    Managers’ use of auditors in decision processes is well known in theaccounting literature, but little is known about owner-managers in innovativefirms and their acquisition of accounting knowledge through direct contactswith external auditors. We conducted a multiple embedded study of exploratorycharacter based on 21 interviews with owner-managers and external auditorsconnected to six innovative firms. We show that owner-managers in innovativefirms apply informal management control in early phases of the innovationprocess and thus also rely heavily on external auditors for such purposes.However, management’s acquisition of accounting knowledge may contributeover time to the development of a more formalised control system as theircompetence increases. This study suggests that a competence-based view maybe useful for understanding the role of accounting and external auditors ininnovative firms’ management control systems.

    Enabling variation of manufacturing process parameters in early stages of product development2006Ingår i: Proceedings of IMECE 2006, American Society of Mechanical Engineers , 2006, Vol. IMECE2006-14459, s. 1165-1173Konferensbidrag (Refereegranskat)
    Abstract [en]

    Currently, mechanical design of aero engine structural components is defined by dimensioning of Design Parameters (DP's) to meet Functional Requirements (FR's). FR's are typically loads, geometrical interfaces and other boundary conditions. Parameters from downstream processes are seldom actually seen as DP's. This paper proposes that downstream process parameters are treated as DP's which calls for engineering methods that can define and evaluate these extended set of DP's.Using the proposed approach manufacturing process alternatives can be used as DP's in early stages of product development. Both the capability to quantitatively assess impact of varying manufacturing DP's, and the availability of these design methods are needed to succeed as an early phase design method. One bottleneck is the preparation time to define and generate these advanced simulation models.This paper presents how these manufacturing process simulations can be made available by automating the weld simulation preparation stages of the engineering work. The approach is based on a modular approach where the methods are defined with knowledge based engineering techniques-operating close to the CAD system.Each method can be reused and used independently of each other and adopted to new geometries. A key advantage is the extended applicability to new products, which comes with a new set of DP's.On a local level the lead time to generate such manufacturing simulation models is reduced with more than 99% allowing manufacturing process alternatives to be used as DP's in early stages of product development.

    Multidisciplinary design tool for conceptual design and evaluation2005Ingår 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 actual product ownership often remains with the manufacturer as functional (total care) products emerge in aerospace business agreements. The business risk is then transferred to the manufacturer why downstream knowledge needs to be available in the concept phase to consider all product life cycle aspects. The aim of this work is to study how a multidisciplinary design tool can be used to embed downstream processes for conceptual design and evaluation allowing simulation of life cycle properties. A knowledge enabled engineering approach was used to capture the engineering activities for design and evaluation of jet engine component flanges. For every design change, cost of manufacturing operations, maintenance and performance aspects can be directly assessed. The design tool assures that the engineering activities are performed accordingly to company design specification which creates a better control over the process quality. It also creates a better understanding enabling the engineers to optimize the concept in real time from an overall product life cycle view. The new tool will be the base for optimize the total product system and will be used not only between companies but also between product development departments in large global companies.

    Searching wide or deep?: absorptive capacity, slack resources and the role of external search in small firm growth2011Ingår i: Frontiers of Entrepreneurship Research, ISSN 0740-7416, Vol. 31, nr 15Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Firms often conduct external search for new opportunities, but not all search leads to growth. Integrating traditional explanations of search from behavioral theory with biological foraging models, we explain how absorptive capacity together with financial slack influence breadth or depth of search. Our findings from 291 small Swedish technology firms indicate that higher absorptive capacity increases search. Absorptive capacity had a stronger effect on breadth of search than for depth of search. We find that only depth of search leads to higher growth for small firms. Further, financial slack strengthened the absorptive capacity and search depth relationship of search relationship, but weakened the relationship between absorptive capacity and breadth of search. The findings are consistent with foraging models that account for resource availability.

    Assessment of eco-labelling criteria development from a strategic sustainability perspective2011Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 19, nr 14, s. 1631-1638Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To turn current patterns of consumption and production in a sustainable direction, solid and understandable market information on the socio-ecological performance of products is needed. Eco-labelling programmes have an important role in this communication. The aim of this study is to investigate what gaps there may be in the current criteria development processes in relation to a strategic sustainability perspective and develop recommendations on how such presumptive gaps could be bridged. First a previously published generic framework for strategic sustainable development is described and applied for the assessment of two eco-labelling programmes. Data for the assessment is collected from literature and in semi-structured interviews and discussions with eco-labelling experts. The assessment revealed that the programmes lack both an operational definition of sustainability, and a statement of objectives to direct and drive the criteria development processes. Consequently they also lack guidelines for how product category criteria might gradually develop in any direction. The selected criteria mainly reflect the current reality based on a selection of negative impacts in ecosystems, but how this selection, or prioritization, is made is not clearly presented. Finally, there are no guidelines to ensure that the criteria developers represent a broad enough competence to embrace all essential sustainability aspects. In conclusion the results point at deficiencies in theory, process and practice of eco-labelling, which hampers cohesiveness, transparency and comprehension. And it hampers predictability, as producers get no support in foreseeing how coming revisions of criteria will develop. This represents a lost opportunity for strategic sustainable development. It is suggested that these problems could be avoided by informing the criteria development process by a framework for strategic sustainable development, based on backcasting from basic sustainability principles.
