    A new paradigm for the continuous alignment of business and IT: combining enterprise architecture modelling and enterprise ontology
    (Elsevier, 2016) Hinkelmann, Knut; Gerber, Aurona; Karagiannis, Dimitris; Thönssen, Barbara; van der Merwe, Alta; Woitsch, Robert [in: Computers in Industry]
    The paper deals with Next Generation Enterprise Information Systems in the context of Enterprise Engineering. The continuous alignment of business and IT in a rapidly changing environment is a grand challenge for today’s enterprises. The ability to react timeously to continuous and unexpected change is called agility and is an essential quality of the modern enterprise. Being agile has consequences for the engineering of enterprises and enterprise information systems. In this paper a new paradigm for next generation enterprise information systems is proposed, which shifts the development approach of model-driven engineering to continuous alignment of business and IT for the agile enterprise. It is based on a metamodelling approach, which supports both human-interpretable graphical enterprise architecture and machine-interpretable enterprise ontologies. Furthermore, next generation enterprise information systems are described, which embed modelling tools and algorithms for model analysis.

    An agile and ontology-aided modeling environment
    (Springer, 2018) Laurenzi, Emanuele; Hinkelmann, Knut; van der Merwe, Alta; Buchmann, Robert Andrei; Karagiannis, Dimitris; Kirikova, Marite [in: The Practice of Enterprise Modeling. 11th IFIP WG 8.1 Working Conference, PoEM 2018, Vienna, Austria, October 31-November 2, 2018, proceedings]
    Enterprise knowledge is currently subject to ever-changing, complex and domain-specific modeling requirements. Assimilating these requirements in modeling languages brings the benefits associated to both domain-specific modeling languages (DSMLs) and a baseline of well-established concepts. However, there are two problems that hamper the speed and efficiency of this activity: (1) the separation between the two key expertise: language engineering and domain knowledge, and (2) the sequential modeling language engineering life-cycles. In this work, we tackle these two challenges by introducing an Agile and Ontology-Aided approach implemented in our Modeling Environment - the AOAME. The approach seamlessly integrates meta-modeling and modeling in the same modeling environment, thus cooperation between language engineers and domain experts is fostered. Sequential engineering phases are avoided as the adaptation of the language is done on-the-fly. To this end, a modeling language is grounded with an ontology language providing a clear, unambiguous and machine-interpretable semantics. Mechanisms implemented in the AOAME ensure the propagation of changes from the modeling environment to the graph-based database containing the ontology.

    Business Process as a Service (BPaaS): The Smart BPaaS Design Environment
    (2016) Woitsch, Robert; Hinkelmann, Knut; Juan Ferrer, Ana Maria; Yuste, Joaquin Iranzo; Karagiannis, Dimitris; Schlamberger, Niko [in: Proceedings of CAiSE 2016 Industry Track]
    This paper introduces the project idea of Business Processes as a Services (BPaaS) that is worked out in the H2020 project CloudSocket. Concept models and semantics are used to align domain specific business processes with executable workflows that are deployed and in production in a multi-cloud environment. The Business Process Management System Paradigm (BPMS) is requesting the functional capabilities of the so-called BPaaS Environments (i) design, (ii) allocation, (iii) execution and (iv) evaluation, which technically compose the CloudSocket Broker platform. This paper introduces first findings of aligning customers’ business needs with BPaaS cloud offerings using a model-based approach.

    Business Process Flexibility and Decision-aware Modeling - The Knowledge Work Designer
    (Springer, 2016) Hinkelmann, Knut; Karagiannis, Dimitris; Mayr, Heinrich C.; Mylopoulos, John [in: Domain-Specific Conceptual Modeling]
    This chapter describes the Knowledge Work Designer, a modelling method for knowledge work. It is based on two principles: (1) the separation of business logic and process logic and (2) the support of both structures and unstructured knowledge. Process logic can be represented in a structured way in BPMN and in a non-structured way with CMMN. For real processes there is no strict separation between structured processes and cases. Therefore the Knowledge Work Designer offers a deep integration of BPMN and CMMN. Business logic can be represented in a structured way using decision tables. Unstructured business logic can be represented in documents. The separation of business logic and process logic allows for simpler process model and easier maintenance.

    PROMOTE - Methodologie und Werkzeug für geschäftsprozessorientiertes Wissensmanagement
    (Springer, 14.05.2002) Hinkelmann, Knut; Karagiannis, Dimitris; Telesko, Rainer; Abecker, Andreas; Hinkelmann, Knut; Maus, Heiko; Müller, Heinz Jürgen [in: Geschäftsprozessorientiertes Wissensmanagement. Effektive Wissensnutzung bei der Planung und Umsetzung von Geschäftsprozessen]
    Erfolgreiches Wissensmanagement setzt voraus, dass es in die tägliche Arbeit integriert ist, wie sie durch die Geschäftsprozesse eines Unternehmens vorgegeben wird. Wissensmanagement muss deshalb als integraler Bestandteil von Geschäftsprozessen und deren Gestaltung betrachtet werden. Wissen ist für ein Unternehmen relevant, wenn es die Geschäftsprozesse verbessert. In diesem Buch werden praxisrelevante Techniken und Vorgehensweisen beschrieben, mit deren Hilfe relevantes Wissen identifiziert, gesichert und gezielt zur Bearbeitung von Prozessaktivitäten bereitgestellt werden kann.
