    Recombinant Service Systems Engineering
    (Business & Information Systems Engineering: Vol. 60, No. 5, 2018) Beverungen, Daniel; Lüttenberg, Hedda; Wolf, Verena
    Although many methods have been proposed for engineering service systems and customer solutions, most of these approaches give little consideration to recombinant service innovation. 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. The paper discusses how these deficiencies can be remedied and designs a revised service systems engineering approach that reorganizes service engineering processes according to four design principles. The method is demonstrated with the recombinant design of a service system for predictive maintenance of agricultural machines.

    Requirements Engineering für Product Service Systems
    (Wirtschaftsinformatik: Vol. 53, No. 6, 2011) Berkovich, Marina; Leimeister, Jan Marco; Krcmar, Helmut
    Produzierende und dienstleistende Unternehmen bieten immer häufiger kundenspezifische Problemlösungen in Form von integrierten Bündeln aus Hardware, Software und Dienstleistungen an, die Product Service Systems (PSS) oder hybride Produkte genannt werden. Eine erfolgreiche Entwicklung eines PSS basiert auf einem tiefgehenden Verständnis der an die Lösung gestellten Anforderungen, weswegen das Requirements Engineering (RE) eine zentrale Rolle im Entwicklungsprozess von PSS spielt. Der Artikel untersucht den State of the Art des RE für PSS auf Basis einer Literaturanalyse in den drei an ihrer Entwicklung beteiligten Domänen Produkt-, Software- und Dienstleistungsentwicklung. Hierzu werden Kriterien, die ein RE-Ansatz für PSS erfüllen muss, aus den Eigenschaften von PSS und den Aufgabenbereichen des RE im Lebenszyklus von PSS abgeleitet. Basierend auf diesen Kriterien werden führende Arbeiten des RE auf ihre Eignung für PSS überprüft. Eine der wichtigsten Erkenntnisse ist, dass Ansätze zum integrierten/domänenübergreifenden RE für PSS fast gänzlich fehlen. Darüber hinaus ist zu erkennen, dass der Reifegrad der RE-Ansätze in den unterschiedlichen Domänen stark variiert. Die untersuchten Ansätze greifen in hohem Maße auf Konzepte und Lösungsmerkmale der jeweiligen Domäne zurück, sodass eine Übertragung auf andere Domänen weitgehend unmöglich ist. Die hier vorgestellte Literaturanalyse schafft eine notwendige Grundlage für erfolgreiches RE für PSS und insbesondere für Arbeiten, die eine konzeptionelle und logische Verbindung zwischen den Anforderungsmodellen der Produkt-, Dienstleistungs- und Softwareentwicklung aufstellen wollen, um hierdurch ein durchgängiges und integriertes RE für PSS zu ermöglichen.AbstractIn recent years, manufacturing companies and service providers have moved towards offering customer-specific problem solutions. These integrated bundles usually consist of hardware, software, and service components and are called product service systems (PSS) or hybrid products. Since the success of the resulting solution depends on the understanding of all requirements, requirements engineering (RE) has become a key factor. The article analyzes the state of the art of RE for PSS based on an extensive literature review in the domains of product-, software-, and service engineering. For this, criteria are derived from the characteristics of PSS and from the task area of RE in the life cycle of PSS. Based on these criteria we analyze the most established RE approaches for their suitability for PSS. An important finding is that integrated/interdisciplinary approaches for RE are missing. Moreover, the maturity of RE approaches in the three domains varies significantly. All analyzed approaches heavily rely on concepts and solution characteristics of their own domain so that a transfer to other domains is hardly possible. This literature review lays the foundation for successful RE for PSS and especially for future research aiming at combining and integrating RE approaches and models of product-, software-, and service engineering. Such requirement models could connect concepts of single domains and enable an integrated and seamless RE for PSS.

    User-Centered Requirements for Augmented Reality as a Cognitive Assistant for Safety-Critical Services
    (Business & Information Systems Engineering: Vol. 65, No. 2, 45017) Bräker, Julia; Osterbrink, Anna; Semmann, Martin; Wiesche, Manuel
    Augmented reality (AR) is widely acknowledged to be beneficial for services with exceptionally high requirements regarding knowledge and simultaneous tasks to be performed and are safety-critical. This study explores the user-centered requirements for an AR cognitive assistant in the operations of a large European maritime logistics hub. Specifically, it deals with the safety-critical service process of soil sounding. Based on fourteen think-aloud sessions during service delivery, two expert interviews, and two expert workshops, five core requirements for AR cognitive assistants in soil sounding are derived, namely (1) real-time overlay, (2) variety in displaying information, (3) multi-dimensional tracking, (4) collaboration, and (5) interaction. The study is the first one on the applicability and feasibility of AR in the maritime industry and identifies requirements that impact further research on AR use in safety-critical environments.
