    A Product-Service System Proposal for Agile Modelling Method Engineering on Demand: ADOxx.org
    (Digital Enterprise Computing (DEC 2017), 2017) Efendioglu, Nesat; Woitsch, Robert; Utz, Wilfrid; Falcioni, Damiano
    The importance of Modelling Method Engineering is equally rising with the importance of domain specific modelling methods and individual modelling approaches. In order to capture the most relevant semantic primitives that address domain specifics needs, it is necessary to involve both, method engineers as well as domain experts. Due to complexity of conceptualization of a modelling method and development of regarding modelling tool, there is a need of a guideline-, corresponding tools- and services-bundle supporting actors with different background along this complex process. Based on practical experience in business, more than twenty EU projects and other research initiatives, this paper introduces a product-service system to support the conceptualization of a modelling method on demand. The proposed product-service system is introduced and evaluated by three EU-funded research projects in the domain of multi-stage manufacturing, e-learning and cloud computing as well as additionally by an in-house development project in the area of decision modelling extensions. The paper discusses the evaluation results and derived outlooks.

    Appflation - A phenomenon to be considered for future digital services
    (Digital Enterprise Computing (DEC 2015), 2015) Benzerga, Sheherazade; Pretz, Michael; Riegg, Andreas; Bounfur, Ahmed; Reimann, Wilfried
    In recent years, the society has experienced a remarkable change that induced shifts in behavior of people and companies. This effect is reinforced by the evolution of current and the emergence of new technologies such as Smartphones. In this paper it is aimed to contribute to the establishment of a research area for both academic and industrial researchers on what will be described in the following as appflation. First a brief evaluation of the effects of mobile devices and application services on the ongoing digital transformation and the customer/company relationship is provided. Second a definition of appflation is given and the origin and impact of this phenomenon is analyzed by considering the customer and the company side. This analysis is supported by a survey amongst Smartphone users, generally confirming that amongst a vast number of installed apps only a very small number actually is used. Additionally, this survey was used to briefly analyze the usage behavior of the participants in relation to the so called primary IT trends. Finally, in order to encourage researchers to advance the field future areas of interest are identified and drivers that will affect the appflation phenomenon in the future are outlined.

    Application of process mining for improving adaptivity in case management systems
    (Digital Enterprise Computing (DEC 2015), 2015) Heber, Eberhard; Hagen, Holger; Schmollinger, Martin
    The character of knowledge-intense processes is that participants decide the next process activities on base of the present information and their expert knowledge. The decisions of these knowledge workers are in general non-deterministic. It is not possible to model these processes in advance and to automate them using a process engine of a BPM system. Hence, in this context a process instance is called a case, because there is no predefined model that could be instantiated. Domain-specific or general case management systems are used to support the knowledge workers. These systems provide all case information and enable users to define the next activities, but they have no or only limited activity recommendation capabilities. In the following paper, we present a general concept for a self-learning system based on process mining that suggests the next best activity on quantitative and qualitative data for a given case. As a proof of concept, it was applied to the area of insurance claims settlement.

    Applying the Minimal Cost of Change Approach to inductive Reference Enterprise Architecture Development
    (Digital Enterprise Computing (DEC 2017), 2017) Timm, Felix; Sauer, Valentina
    Enterprise architectures (EA) help organizations to analyze interrelations among their strategy, business processes, responsibilities, application landscape and information structures. Such ambitious endeavors can be supported by using reference models for EAM. Although research thoroughly addresses the development of reference models, the characteristics of EA models are not investigated in this context. Our work therefore applies one approach for inductively constructing reference process models to the EA domain. We thus contribute to the reference modeling research field in general and its application to development of reference enterprise architectures in detail.

    Automatisiertes Data Discovery innerhalb eines Provisionierungstools
    (Digital Enterprise Computing (DEC 2015), 2015) Bonhorst, Heiko; Kopf, Patrick; Meawad, Fekkry
    Das Provisioning Tool automaIT wurde prototypisch um die Möglichkeit eines Data Discovery erweitert, mit dem Ziel nicht durch automaIT verwaltete Systeme anbinden und steuern zu können. Daten aus dem Data Discovery werden mittels dem Tool Facter gesammelt und können dynamisch in ausführbare Modelle von automaIT integriert und ausgewertet werden. Dadurch kann der Verlauf weiterer Provisionierungsschritte gesteuert werden, ohne dass es eines manuellen Eingriffs bedarf.

    Bottom-up EA Management Governance using Recommender Systems
    (Digital Enterprise Computing (DEC 2015), 2015) Govedarski, Konstantin; Hauptman, Claudius; Schweda, Christian
    Enterprise Architecture (EA) Management is an activity that seeks to foster the alignment of business and IT, and pursues various goals further operationalizing this alignment. Key to effective EA Management is a framework that defines the roles, activities, and viewpoints used for EA Management in accordance to the concerns that the stakeholders aim to address. Consensus holds that such frameworks are organization-specific and hence they are designed in governance activities for EA Management. As of today, top-down approaches for governance are used to derive organization-specific frameworks. These usually lack systematic mechanisms for improving the framework based on the feedback of the responsible stakeholders. We outline a bottom-up approach for EA Management governance that systematically observes the behavior of the actors to learn user concerns and recommend appropriate viewpoints. With this approach, we complement traditional top-down governance activities.

    Building Brand Love: A Dynamic Capabilities Approach
    (Digital Enterprise Computing (DEC 2017), 2017) Rossmann, Alexander; Wilke, Tim
    This paper investigates the impact of dynamic capabilities (DC) on brand love. From a resource-based view, there is little clarity vis-à-vis the specific capabilities that drive the ability to create brand love. This paper focuses on three research questions: Firstly, which dynamic capabilities are relevant for brand love? Secondly, how strong is the impact of certain dynamic capabilities on brand love? Thirdly, which conditions mediate and moderate the impact of specific dynamic capabilities on brand love? Data from a multi-method research approach have been used to identify the specific capabilities that corporations need, to enhance brand love. Furthermore, a standardized online survey was conducted on marketing executives and evaluated by structural equation modeling. The results indicate, that customer expertise plays a major role in the relationship between dynamic capabilities and brand love. Furthermore, this relationship is more important in markets that have a low competitive differentiation in products and services.

    Challenges with Problem Exploration and Validation in the B2B Domain
    (Digital Enterprise Computing (DEC 2017), 2017) Bohn, Feline; Glasbrenner, Annika; Tränkle, Sascha
    Developing new products and services, which create value for customers in dynamic business environments, is highly challenging. A deep understanding of potential customers and their problems is required before deciding which features or capabilities to develop. In order to gain a better understanding of the problems it is helpful to engage with potential customers, ask them about their pains and listen closely to what they say. Lean and agile product management approaches provide techniques for exploring problems, revealing the underlying problem-related assumptions, and validating problems. Until now, these methods have been mainly used in Business-to-Consumer (B2C) domains. There is a lack of reported experience and knowledge about challenges when applying problem exploration and validation techniques in the Business-to-Business (B2B) domain. This article presents a case study about a product development effort in a large IT company offering software-intensive products and services in the B2B domain. The objective of the study is to identify the B2B-specific challenges with respect to problem exploration and validation. Results from the case study show that the huge number of various problems and their variations in B2B contexts, partially caused by different company environments, makes it difficult to identify the most relevant problems and to align them with a suitable customer segment. By utilizing an approach that iterates problem exploration and problem validation, it is possible to create a ranked problem list that can support customer segmentation and guide the product development.
