The tension between the two megatrends of digitization and servitization leads to new hybrid market offerings, so-called smart services. Corresponding business models and value networks fundamentally differ from traditional ones. Developing smart services requires an advanced management of business models and new competences in young disciplines, while their provision requires new internal and external organizational structures or processes. To strengthen their competitive position, manufacturing companies need to extend their business model portfolios and adapt their value networks. However, the highly complex transformation of value creation especially challenges small and medium-sized companies due to limited competences and resources. They must consider opening their boundaries and collaborating with partners. In this chapter, we introduce a basic framework for designing smart services and present a methodology for the planning of a smart service business integrating external partners. The methodology is structured into five phases: Examination of smart service portfolio, analysis of business models and environment, business model portfolio planning, competence identification and analysis, and value creation planning. The methodology is explained by an example on cable marker printers.","lang":"eng"}],"publication":"Managing Digital Open Innovation","doi":"10.1142/9789811219238_0010","language":[{"iso":"eng"}],"series_title":"Open Innovation: Bridging Theory and Practice","date_updated":"2022-01-06T06:54:26Z","publication_status":"published","year":"2020","title":"Planning a Smart Service Business Integrating External Partners","author":[{"id":"43136","first_name":"Christian","orcid":"https://orcid.org/0000-0001-7992-6399","last_name":"Koldewey","full_name":"Koldewey, Christian"},{"id":"33669","last_name":"Reinhold","first_name":"Jannik","full_name":"Reinhold, Jannik"},{"full_name":"Dumitrescu, Roman","first_name":"Roman","last_name":"Dumitrescu","id":"16190"}],"publication_identifier":{"isbn":["978-981-121-923-8"]},"citation":{"mla":"Koldewey, Christian, et al. “Planning a Smart Service Business Integrating External Partners.” <i>Managing Digital Open Innovation</i>, edited by Pierre-Jean Barlatier and Anne-Laure Mention, vol.

However, research on ambidextrous service innovation is scarce. We provide a systematic literature review based on the concepts of ambidexterity, offering two contributions. First, research strands are disconnected, emphasizing either exploration or exploitation of service innovation, despite an organizations’ need to accelerate innovation cycles of exploring and exploiting services. Second, a new framework for ambidextrous service innovation is provided, inspired by the dynamism and generative mechanisms of the ontologically related concept of organizational routines. The framework adopts the perspective of a mutually constitutive relationship between exploring new and exploiting current resources, activities, and knowledge. The findings remedy the scattered literature through a coherent perspective on service innovation that responds to organizations’ needs and guides future research."}],"quality_controlled":"1"},{"publication_status":"published","date_updated":"2022-01-06T07:04:21Z","title":"Service Function Chaining Across OpenStack and Kubernetes Domains","year":"2019","author":[{"id":"60845","full_name":"Razzaghi Kouchaksaraei, Hadi","last_name":"Razzaghi Kouchaksaraei","first_name":"Hadi"},{"full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger","id":"126"}],"doi":"10.1145/3328905.3332505","language":[{"iso":"eng"}],"abstract":[{"text":"Remarkable advantages of Containers (CNs) over Virtual Machines (VMs) such as lower overhead and faster startup has gained the attention of Communication Service Providers (CSPs) as using CNs for providing Virtual Network Functions (VNFs) can save costs while increasing the service agility. However, as it is not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs is proposed. To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments.

In a multi-method study that includes conceptual research and qualitative data from in-depth interviews, we conceptualize “smart service” and “smart service systems” based on using smart products as boundary objects that integrate service consumers’ and service providers’ resources and activities. Smart products allow both actors to retrieve and to analyze aggregated field evidence and to adapt service systems based on contextual data.

A triadic constellation may arise in the context of services for animal companions, for example, when veterinarians provide counsel and treatment to the animal companion and its owner. Through interviews with both owners of animal companions and providers of services for animal companions, this study explores typical constellations and characteristics of the three relationships in this service triad. In line with balance theory, the results show that four distinct types of triadic relationships exist in services for animal companions: the harmonious, the dysfunctional, the challenging, and the doubtful triad.

Recombinant innovation refers to reusing and integrating resources that were previously unconnected. In an age of networked products and data, we can expect that many service innovations will be based on adding, dissociating, and associating existing value propositions by accessing internal and external resources instead of designing them from scratch. The purpose of this paper is to identify if current service engineering approaches account for the mechanisms of recombinant innovation and to design a method for recombinant service systems engineering. In a conceptual analysis of 24 service engineering methods, the study identified that most methods (1) focus on designing value propositions instead of service systems, (2) view service independent of physical goods, (3) are either linear or iterative instead of agile, and (4) do not sufficiently address the mechanisms of recombinant innovation.

Rapid advances in information technology allow for designing novel information systems that enable entirely new configurations of service systems. In turn, Service Science also leaves its mark on the design, adoption, and use of information systems and technology.

Organizations that formerly concentrated on transactional sales thus confront a new challenge associated with managing service usage—retention and extracting value from investments in smart technology. This study combines a marketing and an information systems perspective in a field study conducted jointly with a large European car manufacturer. Understanding the renewal decision for IT-based service contracts requires knowledge from both disciplines. The paper shows that combining behavioral predictor variables stemming from marketing research and technology-related perceptual variables stemming from technology acceptance research increases the explanatory power and prediction accuracy of forecasting models for customer renewal decisions. Specifically, the authors show that perceptions of usefulness become more important the longer customers use IT-based services and the more services they use within the service contract.","lang":"eng"}]},{"author":[{"full_name":"Larivière, Bart","last_name":"Larivière","first_name":"Bart"},{"first_name":"David","last_name":"Bowen","full_name":"Bowen, David"},{"full_name":"Andreassen, Tor W","last_name":"Andreassen","first_name":"Tor W"},{"full_name":"Kunz, Werner","last_name":"Kunz","first_name":"Werner"},{"first_name":"Nancy J","last_name":"Sirianni","full_name":"Sirianni, Nancy J"},{"full_name":"Voss, Chris","first_name":"Chris","last_name":"Voss"},{"id":"36392","first_name":"Nancy","last_name":"Wünderlich","full_name":"Wünderlich, Nancy"},{"full_name":"De Keyser, Arne","first_name":"Arne","last_name":"De Keyser"}],"year":"2017","status":"public","title":"“Service Encounter 2.0”: An investigation into the roles of technology, employees and customers","article_type":"original","date_updated":"2022-01-06T07:01:30Z","publication_status":"published","_id":"4949","language":[{"iso":"eng"}],"publisher":"Elsevier","page":"238--246","user_id":"37741","citation":{"bibtex":"@article{Larivière_Bowen_Andreassen_Kunz_Sirianni_Voss_Wünderlich_De Keyser_2017, title={“Service Encounter 2.0”: An investigation into the roles of technology, employees and customers}, number={79}, journal={Journal of Business Research}, publisher={Elsevier}, author={Larivière, Bart and Bowen, David and Andreassen, Tor W and Kunz, Werner and Sirianni, Nancy J and Voss, Chris and Wünderlich, Nancy and De Keyser, Arne}, year={2017}, pages={238--246} }","ama":"Larivière B, Bowen D, Andreassen TW, et al. “Service Encounter 2.0”: An investigation into the roles of technology, employees and customers. <i>Journal of Business Research</i>. 2017;(79):238--246.","mla":"Larivière, Bart, et al. “‘Service Encounter 2.0’: An Investigation into the Roles of Technology, Employees and Customers.” <i>Journal of Business Research</i>, no. 79, Elsevier, 2017, pp. 238--246.","short":"B.

However, as we argue in this paper, existing MAVT-based methods for measuring attribute importance weights do not fit the shopping tasks for which recommender systems are typically used. These methods assume well-trained decision makers who are willing to invest time and cognitive effort, and who are familiar with the attributes describing the available alternatives and the ranges of these attribute levels. Yet, recommender systems are most often used by consumers who are usually not familiar with the available attributes and ranges and who wish to save time and effort. Against this background, we develop a new method, based on a product configuration process, which is tailored to the characteristics of these particular decision makers. We empirically compare our method to SWING, ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory experiment with 153 participants. Results indicate that our proposed method performs better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms of cognitive load, and that participants were faster with our method than with any other method.

In the B2C field, studies of self-service technology show that perceived risk is an important factor influencing the use of service technology. Though prior research explores different risk types that emerge in consumer settings, risk perception in the B2B setting lacks a detailed examination of different risk types influencing technology-based service adoption. Data from 49 qualitative interviews with providers and customers in two different B2B industries inform this study. The findings emphasize the importance of functional and financial risks in a B2B context and show that business customers' personal and psychological fears hinder their use of technology-based services. Results highlight differences in risk perception and evaluation between customers and providers."}]},{"citation":{"bibtex":"@article{Praetorius_Al-Kabbani_Bohndick_Hilkenmeier_König_Müsche_Sommer_Klingsieck_2016, title={Spielend Lehrer/in werden: problembasiertes Lernen mit virtuellen Schülerinnen/Schülern. }, volume={11}, number={3}, journal={Zeitschrift für Hochschulentwicklung}, author={Praetorius, Saskia and Al-Kabbani, Daniel and Bohndick, Carla and Hilkenmeier, Johanna and König, Sebastian T. and Müsche, Hannah S. and Sommer, Sabrina and Klingsieck, Katrin B.}, year={2016}, pages={213–245} }","ama":"Praetorius S, Al-Kabbani D, Bohndick C, et al.
