- ZeitschriftenartikelSemantic Annotations of Enterprise Models for Supporting the Evolution of Model-Driven Organizations(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 5, 2018) Fill, Hans-GeorgIn model-driven organizations enterprise models are used to represent and analyze the current and future states of aspects such as strategies, business processes or the enterprise architecture. Thereby, the scope of representation and analysis depends on the used modeling method. Although adaptations of modeling methods are frequently conducted to meet requirements emerging from business changes, such modifications may not be favorable due to potential side effects on other enterprise systems, e.g. through inconsistencies with existing standards and resulting conflicts in algorithmic processing. In the paper at hand we therefore propose the use of semantic annotations of enterprise models for dynamically extending the representation and analysis scope of enterprise modeling methods. Through a loose-coupling between enterprise models and formal semantic schemata, additional information can be represented and processed by algorithms without changes in the original modeling language. In this way, the evolution of information requirements of an organization can be satisfied while maintaining the consistency of the used enterprise modeling languages. For illustrating the feasibility of the approach we describe a use case from the area of risk management. The use case is realized using the SeMFIS platform that supports the annotation of enterprise models and the subsequent machine-based analysis of annotations.
- ZeitschriftenartikelA Classification Framework for Service Modularization Methods(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 14, 2018) Pöppelbuß, Jens; Lubarski, AleksanderService modularity has been suggested as a promising concept that can resolve the dilemma between increasing diversification of customer demands and the provider’s need for standardization and efficiency gains. Despite having been in the center of attention amongst service researchers for the past decade, service modularity still remains a rather theoretical concept with little application in practice. Previous publications have contributed conceptual and enterprise modeling methods to achieve modular service architectures by both adjusting product modularization methods to the service domain as well as designing new ones specifically for services. However, up to date, there exists no framework that would systematize and classify these methods concerning their premises as well as underlying modularity principles and objectives. The main contribution of this paper is the development of a framework that can be used to classify existing and future methods for service modularization based on two key dimensions, i. e., the phases of the modularization process and the types of structuring the modular architecture. The developed framework further points out which phases of the overall modularization process are still underdeveloped and how future research can contribute to making service modularity more accessible for practitioners.
- Journal EditorialIntroduction to the Special Issue on Model-Driven Organisations(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 3, 2018) Clark, TonyModern organisations are faced with the very challenging problem of rapidly responding to continual external business pressures in order to sustain their competitiveness or to effectively perform mission-critical services. Difficulties arise because the continual evolution of systems and operational procedures that are performed in response to external pressures eventually lead to suboptimal configurations of systems and processes that drive the organisation.
- ZeitschriftenartikelManaging the Procurement Process in Service Portals – An Automated Matching Approach with Demand-Side Management Methods(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 15, 2018) Behrens, Dennis; Gerwig, Carola; Schoormann, Thorsten; Knackstedt, RalfBecause of technological changes (e. g., Web 2.0 and the Internet of Things), service portals like MyHammer, Blauarbeit, and Amazon Home Services become increasingly important for research and practice. To increase the efficiency of service offers, new procurement methods that link service providers and service consumers are necessary. This article uses a scheduling approach that has been applied primary in the context of energy management: Demand-Side Management (DSM). Generally, DSM methods can be used to shift energy demand to favorable timeslots (e. g., lower-cost timeslots or those that help the energy supplier) to achieve goals like a flattened load profile, minimized costs, and grid reliability. In doing so, we argue that the basic concept of DSM is transferable to enable automatic matching of service offers and demands in a service portal. To explore potential benefits and drawbacks, we analyze service portals, including their functionalities and information needs, and compare them with the approaches offered by DSM. Then a mathematical model of an existing DSM approach is used to model the requirements of service portals. As a result, we conclude that DSM strategies can be useful in automating the procurement procedure in service portals, which facilitates more efficient and effective service offers and executions.
- ZeitschriftenartikelProduct-Service-System – What and why Developers can learn from Mass Customization(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 16, 2018) Gembarski, Paul Christoph; Lachmayer, RolandDespite their very similar objectives, delimitations or associations between the two business types of mass customization and providers of product-service-systems (PSS) cannot be found in literature. In the following article, both business types are compared with each other and mapped into a common businesstypological framework, the product-process-baseline-change matrix. Following that, the development of PSS is characterized especially with regard to the (re-)configurability of PSS over the life-cycle. Since product configuration is one of the key tools in the development and the customer co-design process in mass customization, its application to PSS is evaluated and present PSS-configuration approaches are discussed.
- ZeitschriftenartikelAn Approach to Flexible Multilevel Modelling(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 10, 2018) Macías, Fernando; Rutle, Adrian; Stolz, Volker; Rodriguez-Echeverria, Roberto; Wolter, UweMultilevel modelling approaches tackle issues related to lack of flexibility and mixed levels of abstraction by providing features like deep modelling and linguistic extension. However, the lack of a clear consensus on fundamental concepts of the paradigm has in turn led to lack of common focus in current multilevel modelling tools and their adoption. In this paper, we propose a formal framework, together with its corresponding tools, to tackle these challenges. The approach facilitates definition of flexible multilevel modelling hierarchies by allowing addition and deletion of intermediate abstraction levels in the hierarchies. Moreover, it facilitates separation of concerns by allowing integration of different multilevel modelling hierarchies as different aspects of the system to be modelled. In addition, our approach facilitates reusability of concepts and their behaviour by allowing definition of flexible transformation rules which are applicable to different hierarchies with a variable number of levels. As a proof of concept, a prototype tool and a domain-specific language for the definition of these rules is provided.
- ZeitschriftenartikelCapability-based Communication Analysis for Enterprise Modelling(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 4, 2018) Pastor, Oscar; Ruiz, Marcela; Koç, Hasan; Valverde, FranciscoCapability-oriented enterprise modelling can provide effective solutions to face changing business context. In the business domain, the notion of capability has gained a lot of attention since it guides the activities of service specification and design. Simultaneously, the research community has been promoting the integration of model-driven development (MDD) approaches with enterprise modelling to support the link between enterprise and software specifications. This integration has becoming vital to ensure the traceability of enterprise models and software implementations, acceleration of software time to market, quality assurance, and enterprise model evolution support. The capability-driven development (CDD) method has been recently developed and applied in various industrial use cases. But, the link between the CDD method and strong funded MDD approaches has not been explored. In this paper we explore the integration of the CDD method with the Communication Analysis method (a communication-oriented business process modelling method), which is supported by means of MDD frameworks. Among the advantages to add the communicational perspective to the CDD method, we want to highlight the possibility to offer a high level analysis of business process models that focus on the communications between different organisational actors, as so as to offer further transformation facilities into software components. With this integration, we give the first steps to offer automation facilities to capability-driven environments.
- ZeitschriftenartikelThe Next Generation – Design and Implementation of a Smart Glasses-based Modelling System(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 18, 2018) Metzger, Dirk; Niemöller, Christina; Jannaber, Sven; Berkemeier, Lisa; Brenning, Lukas; Thomas, OliverTechnical services in innovative business models are becoming increasingly complex. Thus, comprehensive IT-support is crucial for service delivery. Content for those IT-support systems is captured by modelling relevant service processes. Aside the intangibility and integrativity, services are characterized by the complexity of their structure. So, the traditional modelling approaches executed by modelling experts are challenging. To overcome those challenges, we developed a concept to model service processes at the point-of-service while executing the service itself. The process executer (e. g. the technician) is empowered by smart glasses that do not limit his scope of actions. Additionally, the glasses guide through the (runtime) modelling and allow easy capturing of service processes during the execution. We followed a design science-oriented approach. First, we identified relevant process blocks from literature for runtime modelling (analysis). Afterwards, we built related software components for the process blocks (design). We do so by proposing an implementation and an architecture for a smart glasses-based modelling system. Finally, we evaluated the concept by prototyping and demonstrating the system by means of a real-world service process (evaluation). Our approach tackles challenges on how new technology can enhance the modelling at the point-of-service, which process blocks are relevant and how domain experts can be integrated into the modelling process itself. The practical implications are towards new chances of capturing processes.
- ZeitschriftenartikelWhat we know and what we do not know about DMN(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 2, 2018) Figl, Kathrin; Mendling, Jan; Tokdemir, Gul; Vanthienen, JanThe recent Decision Model and Notation (DMN) establishes business decisions as first-class citizens of executable business processes. This research note has two objectives: first, to describe DMN's technical and theoretical foundations; second, to identify research directions for investigating DMN's potential benefits on a technological, individual and organizational level. To this end, we integrate perspectives from management science, cognitive theory and information systems research.
- ZeitschriftenartikelEnterprise Modeling in Support of SOA Migration Analysis(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 1, 2018) de Kinderen, Sybren; Kaczmarek-Heß, MonikaThis paper shows how enterprise modeling can support a Service-Oriented Architecture (SOA) migration analysis in terms of (1) IT infrastructure understanding, (2) identifying and refining candidate services by means of analyzing both the current IT infrastructure capabilities and business concerns, as well as (3) understanding how candidate services build on the current IT infrastructure. Based on requirements derived from a conducted literature study on SOA analysis and SOA migration projects, we identify the Multi-Perspective Enterprise Modeling (MEMO) method as a suitable language family to support a SOA migration analysis. Furthermore, we extend MEMO's language for IT infrastructure modeling, called ITML, with concepts central to SOA migration, and show how the modeling language can support key phases of a SOA migration project. We also provide a threefold evaluation of our SOA migration modeling approach by means of (1) application to documented SOA migration projects, (2) a scenario-based comparison with ArchiMate, another language that is a promising candidate for a SOA migration analysis, and (3) an assessment against the identified requirements. Finally, we discuss corresponding software tool support.
