Smart Service Innovation: Organization, Design, and Assessment

Anke, Jürgen 27 January 2023 (has links)
Background: The emergence of technologies such as the Internet of Things, big data, cloud computing, and wireless communication drives the digital transformation of the entire society. Organizations can exploit these potentials by offering new data-driven services with innovative value propositions, such as carsharing, remote equipment maintenance, and energy management services. These services result from value co-creation enabled by smart service systems, which are configurations of people, processes, and digital technologies. However, developing such systems was found to be challenging in practice. This is mainly due to the difficulties of managing complexity and uncertainty in the innovation process, as contributions of various actors from multiple disciplines must be coordinated. Previous research in service innovation and service systems engineering (SSE) has not shed sufficient light on the specifics of smart services, while research on smart service systems lacks empirical grounding. Purpose: This thesis aims to advance the understanding of the systematic development of smart services in multi-actor settings by investigating how smart service innovation (SSI) is conducted in practice, particularly regarding the participating actors, roles they assume, and methods they apply for designing smart service systems. Furthermore, the existing set of methods is extended by new methods for the design-integrated assessment of smart services and service business models. Approach: Empirical and design science methods were combined to address the research questions. To explore how SSI is conducted in practice, 25 interviews with experts from 13 organizations were conducted in two rounds. Building on service-dominant logic (SDL) as a theoretical foundation and a multi-level framework for SSI, the involvement of actors, their activities, employed means, and experienced challenges were collected. Additionally, a case study was used to evaluate the suitability of the Lifecycle Modelling Language to describe smart service systems. Design science methods were applied to determine a useful combination of service design methods and to build meta-models and tools for assessing smart services. They were evaluated using experiments and the talk aloud method. Results: On the macro-level, service ecosystems consist of various actors that conduct service innovation through the reconfiguration of resources. Collaboration of these actors is facilitated on the meso-level within a project. The structure and dynamics of project configurations can be described through a set of roles, innovation patterns, and ecosystem states. Four main activities have been identified, which actors perform to reduce uncertainty in the project. To guide their work, actors apply a variety of means from different disciplines to develop and document work products. The approach of design-integrated business model assessment is enabled through a meta-model that links qualitative aspects of service architectures and business models with quantitative assessment information. The evaluation of two tool prototypes showed the feasibility and benefit of this approach. Originality / Value: The results reported in this thesis advance the understanding of smart service innovation. They contribute to evidence-based knowledge on service systems engineering and its embedding in service ecosystems. Specifically, the consideration of actors, roles, activities, and methods can enhance existing reference process models. Furthermore, the support of activities in such processes through suitable methods can stimulate discussions on how methods from different disciplines can be applied and combined for developing the various aspects of smart service systems. The underlying results help practitioners to better organize and conduct SSI projects. As potential roles in a service ecosystem depend on organizational capabilities, the presented results can support the analysis of ex¬ternal dependencies and develop strategies for building up internal competencies.:Abstract iii Content Overview iv List of Abbreviations viii List of Tables x List of Figures xii PART A - SYNOPSIS 1 1 Introduction 2 1.1 Motivation 2 1.2 Research Objectives and Research Questions 4 1.3 Thesis Structure 6 2 Research Background 7 2.1 Smart Service Systems 7 2.2 Service-Dominant Logic 8 2.3 Service Innovation in Ecosystems 11 2.4 Systematic Development of Smart Service Systems 13 3 Research Approach 21 3.1 Research Strategy 21 3.2 Applied Research Methods 22 4 Summary of Findings 26 4.1 Overview of Research Results 26 4.2 Organizational Setup of Multi-Actor Smart Service Innovation 27 4.3 Conducting Smart Service Innovation Projects 32 4.4 Approaches for the Design-integrated Assessment of Smart Services 39 5 Discussion 44 5.1 Contributions 44 5.2 Limitations 46 5.3 Managerial Implications 47 5.4 Directions for Future Research 48 6 Conclusion 54 References 55 PART B - PUBLICATIONS 68 7 It Takes More than Two to Tango: Identifying Roles and Patterns in Multi-Actor Smart Service Innovation 69 7.1 Introduction 69 7.2 Research Background 72 7.3 Methodology 76 7.4 Results 79 7.5 Discussion 90 7.6 Conclusions and Outlook 96 7.7 References 97 8 Iterative Uncertainty Reduction in Multi-Actor Smart Service Innovation 100 8.1 Introduction 100 8.2 Research Background 103 8.3 Research Approach 109 8.4 Findings 113 8.5 Discussion 127 8.6 Conclusions and Outlook 131 8.7 References 133 9 How to Tame the Tiger – Exploring the Means, Ends, and Challenges in Smart Service Systems Engineering 139 9.1 Introduction 139 9.2 Research Background 140 9.3 Methodology 143 9.4 Results 145 9.5 Discussion and Conclusions 151 9.6 References 153 10 Combining Methods for the Design of Digital Services in Practice: Experiences from a Predictive Costing Service 156 10.1 Introduction 156 10.2 Conceptual Foundation 157 10.3 Preparing the Action Design Research Project 158 10.4 Application and Evaluation of Methods 160 10.5 Discussion and Formalization of Learning 167 10.6 Conclusion 169 10.7 References 170 11 Modelling of a Smart Service for Consumables Replenishment: A Life Cycle Perspective 171 11.1 Introduction 171 11.2 Life Cycles of Smart Services 173 11.3 Case Study 178 11.4 Discussion of the Modelling Approach 185 11.5 Conclusion and Outlook 187 11.6 References 188 12 Design-integrated Financial Assessment of Smart Services 192 12.1 Introduction 192 12.2 Problem Analysis 195 12.3 Meta-Model Design 200 12.4 Application of the Meta-Model in a Tool Prototype 204 12.5 Evaluation 206 12.6 Discussion 208 12.7 Conclusions 209 12.8 References 211 13 Towards a Cost-Benefit-Analysis of Data-Driven Business Models 215 13.1 Introduction 215 13.2 Conceptual Foundation 216 13.3 Methodology 218 13.4 Case Analysis 220 13.5 A Cost-Benefit-Analysis Model for DDBM 222 13.6 Conclusion and Outlook 225 13.7 References 226 14 Enabling Design-integrated Assessment of Service Business Models Through Factor Refinement 228 14.1 Introduction 228 14.2 Related Work 229 14.3 Research Goal and Method 230 14.4 Solution Design 231 14.5 Demonstration 234 14.6 Discussion 235 14.7 Conclusion 236 14.8 References 237

Use cases for traceability systems : An explanatory case study about the application areas for QR codes

Strömberg, Oliver January 2023 (has links)
The customer concept becomes more intertwined with the provider of products as serviceoriented business models is offered to the customer. This shift is referred as servitization in which innovation occurs in the company processes by shifting focus from providing products to providing product service systems (PSS). However, the servitization of the manufacturing industry has been slow compared to other sectors and there are many barriers to overcome for the transformation. Use phase data could be used as an enabler to resolve barriers to PSS. The collection of use phase data could be done through the usage of automatic identification technologies like QR codes. Despite the promising opportunities with collection of use phase data there are many challenges. Among them are the identification of use cases for the data. This study therefore aimed to identify both use cases and needed use phase data when collecting data using QR codes.  The manufacturing company Bosch Rexroth AB and their service department were chosen as a case study company, to establish their view on the use cases for QR codes. Additionally, a literature review identified the use phase data need for each use cases derived from the theory. The collected data was analyzed through an explanation building analysis in which plausible and rival explanations to the result was brought up. This resulted in five identified use cases for QR codes and from the use cases one identified need for use phase data. The identified use cases mainly providing value to the provider were derivation of new products or services and improvement of current products or services. The identified use cases mainly providing value to the external customer were the offering of predictive maintenance, the assistance in operations and the creation of a digital passport or image. The identified use phase data need was service data but also additional product related data that does not concern use phase of the products was also needed for the use cases.

Guan, Hao 14 October 2019 (has links)
Au cours des deux dernières décennies, l'économie industrielle a fait un pas dans l'économiedes services. De nombreuses illustrations témoignent de cette évolution comme le montrent lesnouveaux modèles d’affaires mis en oeuvre par les industriels. Ceux ci sont de plus en plusnombreux à passer de la logique traditionnelle axée sur la vente de s produits à la lo gique« servicielle » qui se focalise sur les effets utiles et la performance d’usage de la solution par lesparties prenantes . Dans ce contexte, les systèmes produits services (PSS) sont considérés commel’ une des mises en oeuvre possibles de la servitisat ion des entreprises manufacturières qui, desurcroît, s’annonce comme une possibilité prometteuse au plan du développement durable. Les PSSattire nt en conséquence l'attention de nombreux praticiens et chercheurs en raison de leur potentiel àsatisfaire le s exigences des clients par des solutions plus économiques, plus personnalisé e s et plusdurables. Cependant, dans le marché actuel, la plupart des solutions PSS sont poussées par lesfournisseurs en fonction de leurs propres capacités et de leur potentiel interne d'innovation sanstenir compte, la plupart du temps d es utilisations et d es valeurs réelles que représentent les offresproposées aux bénéficiaires. Il en résulte que les fonctionnalités des offres, souvent modulaires(différents scénarios de combinaisons de produits et de services ), sont parfois inutiles, parfoisredondantes et qu’ une grande quantité de déchets est produite lors de la production et de la mise enoeuvre de ce type de solution s ; ce qui est antinomique avec l’effet recherchéCet te thèse associe un concept complémentaire au concept de PSS existant pour obtenir unPSS orienté client (COPSS) qui se concentre sur les exigences des clients et leur satisfaction, sur laperformance économique de la solution, sur les autres exigences des fournisseurs de la solution,ainsi que sur la performance de la solution en terme de développement durable. A fin de concevoirdes solutions COPSS répondant véri table ment à ce cahier des charges , un cadre de conceptionintégré basé sur une approche tridime nsionnelle d'ingénierie simultanée est proposé. Selon ce cadre,la solution est construite en considérant simultanément la conception de la solution (offre COPSS),la conception des processus et d u réseau support à cette offre. C e cadre adopte plus précisé ment lapersonnalisation de masse comme méthodologie de conception de base pour concevoir l es offres etles processus supports et l’ architecture multi agent AGORA pour concevoir le réseau support. Afind’être éprouvé, le cadre proposé est mis en oeuvre sur un cas d’application / The world industrial economy has been witnessing to step into service economyduring last two decades. Evidence can be easily found to prove it, such as the shift ofmore and more manufacturers from traditional product centric logic intoservice oriented logic, sharing economy’s growth in popularity over the last severalyears, changing their business model and renting the usage of the p roduct theymanufacture, etc. Product Service Systems (PSS), under this context, are seen as onesolution to help companies to address the servitization process. PSS captures a lot ofpractitioners and researchers’ attention because of its potential to sat isfy customers’requirements of more economical, more c ustomized and more sustainable services inthe modern service economy context. However, in the current marketplace, most PSSsolutions are pushed by providers based on their own capabilities and their internalpotential for innovations and unfortunately, they most of the time ignore real usagesand values for beneficiaries.

Interference cancellation for collocated wireless radios

Raghavan, Anand 29 June 2007 (has links)
The area of deterministic noise cancellation in mobile radio communication systems is investigated and analyzed. Several interoperation problems in the mobile wireless radio space are identified and interference concerns for the Bluetooth - WLAN networks are characterized and quantified in the physical layer. A mathematical framework has been created for describing interference in the 2.4 GHz band. An adaptive noise suppression system has been developed that is able to alleviate the encroachment of the aggressor signal on the victim without sacrificing any of the original signal. This system is demonstrated to improve the victim SNR in a spread spectrum communication scenario. The research is extended to construct an interference canceller that is easy to assimilate into existing RF front-ends. A low-power small form-factor analog active canceller has been designed in 0.18-ìm Si-CMOS IC technology that delivers adequate noise suppression performance while operating in the RF domain. This includes novel implementations of phase rotator circuits based on delay interpolation and an integrated low-current quadrature modulator-based continuously variable analog phase shifter. This canceller is capable of up to 30 dB of in-band cancellation for the Bluetooth - WLAN problem. Other versions of the canceller are configured to protect GPS and DVB-H receivers from unintentional radiators transmitting in the vicinity. These demonstrate noise mitigation of at least 15 dB in their respective bands while generating very low broadband noise at the output. A simple low-power mixed-signal automatic control mechanism is also developed to operate the canceller adaptively. The work described in this dissertation advances the state-of-the-art in the area of mobile wireless radio coexistence.

Assessment of building service systems process integration applying exergy critrerion / Pastato inžinerinių sistemų procesų integravimo vertinimas taikant eksetrgijos kriterijų

Biekša, Darius 05 June 2008 (has links)
A significant part of world energy consumption balance, approx. 40 %, is utilized in buildings. Maintenance of comfortable conditions and improvement in the living, working or recreational environment is a desire for every human. Therefore it is no surprise that there has been a sudden increase in scientific research in the field of building’ energy efficiency. Despite the relevance of the problem there is no sustaining methodology for evaluating building’ energy efficiency by applying sustainable energy development approach. The majority of the researchers don’t assess different potential of the analyzed energy flows nor systems operational regimes. The aim of the work is to evaluate the possibilities for applying exergetical process and system integration method in the design, operation and normalization of the office building service systems: to prepare design solutions that increase buildings’ service systems’ thermodynamical efficiency and covers individual processes and elements’ chain systems. The thesis is divided into the introduction and three main chapters, conclusions, a list of literature and a list of publications. In this work the building service systems’ analysis incorporates three interconnected methods: system analysis, life cycle and thermodynamical analysis. Application of system analyses enables an estimation of service system’s elements (subsystems) and their interconnections. Life cycle analysis allows estimation of total exergy demand through the...

The stakes of circulation in sustainable societies : logistics and functional economy / Les Enjeux de la circulation dans les sociétés durables : logistique et économie de fonctionnalité

Dente, Sébastien 11 September 2013 (has links)
Les économies circulaires et de fonctionnalité sont souvent présentées comme des stratégies prometteuses quant à leur capacité à résoudre les problèmes environnementaux associés aux systèmes de production et de consommation actuels. Cependant, malgré les consommations d’énergie et émissions croissantes associées à la mondialisation de nos systèmes modernes, la question de la circulation reste peu abordée. Le présent travail s’attache à combler ce manque en analysant les effets de la représentation des activités humaines et des processus de circulation sous le champ de la durabilité. En s’intéressant ainsi au triptyque durabilité/chaîne d’approvisionnement/ économies circulaires et de fonctionnalités, le présent travail montre notamment la barrière à la durabilité que constitue la représentation standardisée de l’espace et du temps associée à la convention économique actuellement dominante. Ainsi, l’approche en circuit fermé de l’économie circulaire et l’approche servicielle de co-production associée à l’économie de fonctionnalité ne s’avèrent être des stratégies efficacement durables que si une approche spécifique des ressources et de la demande y est associée. Ce point a notamment été développé à travers un modèle logistique qui montre par rapport à un scénario logistique de référence une augmentation de 5% des émissions de CO2 liés au transport de marchandises entre régions françaises pour une approche générique de l’économie de fonctionnalité contre une diminution de 3% des émissions dans le cas d’une approche spécifique / Functional and circular economies are often presented as promising strategies to address the environmental issues associated with our modern production/consumption systems. Within these systems, the circulation processes themselves are usually poorly addressed, in spite of the increasing energy consumption and emissions associated with logistics under the current trends of globalization. The present thesis aims at filling this gap by analyzing the relationship between the representation of human activities and circulation processes and the issue of sustainability. Dealing with the triptych sustainability/supply chain management/circular and functional economies, the thesis shows that the standardized representation of space and time in the current dominant economic conventions acts as a barrier to the development of truly sustainable circulation processes. It finds that the closing loop approach of the circular economy and the product/service approach of the functional economy require specific definitions and policy measures for resources and demand, so that they can be considered as real sustainable strategies. This necessity to develop specific new approaches was further supported with evidence from a new logistics and freight transportation model for France. The model indicates that a generic approach towards a functional economy would lead to 5% increase of CO2 emissions (associated with French interregional traded tons) while a targeted approach would lead to a 3% reduction in comparison to the reference logistics scenario

Consumer Acceptance, Barriers and Success Factors of Peer-to-Peer Carsharing in Perspective of Connected Car Services and Autonomous Vehicles

Amann, Volker 01 July 2017 (has links) (PDF)
Until now, car ownership has been a symbol of wealth and personal freedom. The high value of the car in society has been enforced by the powerful automotive industry with their well-funded marketing budgets. Currently, there are one billion cars worldwide, possibly increasing to 2,8 billion by 2050. However, the awareness of the negative consequences of car ownership on the environment, cities, and individuals in terms of reduced personal and financial freedom is increasing. The trend towards collaborative consumption involving activities like sharing and trading is leading to a shift from ownership to the access of goods and services. In this context, carsharing is receiving more and more attention and the number of users for B2C carsharing models is increasing exponentially. The least-developed business model with the biggest opportunities in terms of environmental benefits is peer-to-peer carsharing (P2P carsharing). Providers face daunting problems in reaching critical mass, due to a lack of consumer acceptance. Academic contributions on the topic are rare. The goal of this dissertation is to capture the acceptance factors, barriers and success factors for P2P carsharing. Additionally, the phenomenon is explored within the perspective of disruptive technologies, including the connected car and autonomous vehicles. A comprehensive literature review including collaborative consumption, carsharing, and in particular P2P carsharing, has been conducted. A mixed-method approach has been used. Qualitative interviews with leading academic and industry experts in the field of collaborative consumption and shared mobility, as well as a focus group discussion, have been executed. In the quantitative survey, the identified factors have been integrated into the Technological Acceptance Model (TAM), the theoretical foundation of the work. A representative survey was conducted in Austria with 801 respondents. The results were generated by applying a partial least squares analysis. Results show that the TAM model, including the extensions, appeared to be applicable. In particular, people with an innovative mindset are open to the usage of the business model. The main motivational factors for participating are economic, utility and enjoyment. The personal attachment towards one's own car remains one of the main barriers, next to fear of sharing and loss of convenience. Success factors in increasing acceptance are - among others - trust, value-added services and keyless car exchange. The preferred usage model for autonomous vehicles tends to be ownership. Even though the awareness of P2P carsharing is rather low among the Austrian population, 13,6% state that they would use the service. Sharing one's privately owned autonomous vehicle with others met with even higher levels of approval from the respondents. The extension of the TAM, as well as its application to a new field outside information system (IS) research, can be viewed as the major academic contribution of this work. Practical implications for P2P carsharing providers and the automotive industry include strategic recommendations regarding the current disruptive trends within the automotive industry. In particular, concrete measures have been identified to scale the business model by addressing new customers and reducing the identified barriers by providing extensive knowledge of relevant success factors.
