    Beyond Enterprise Architecture Modeling – What are the Essentials to Support Enterprise Transformations?
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Labusch, Nils; Aier, Stephan; Winter, Robert
    In recent years, many different modeling techniques and languages were developed in order to allow for an efficient and appropriate enterprise architecture management (EAM). Recently, EAM is no longer only seen as a means to ensure business/IT alignment but further as a means to support fundamental changes of the organization, often called enterprise transformation (ET). In a joint project with a group of practitioners we aim at developing a framework that provides guidance on how EAM can support such ETs and thus leverage the benefit of modeling. Our design results after more than one year of research reveal different types of EAM, areas of action in ETs and ET activities that can be supported by EAM. The findings show that modeling techniques or languages should focus on constructs like transitions, benefits or risks in order to increase their value for ET support.

    BPMN 2.0 Serialization - Standard Compliance Issues and Evaluation of Modeling Tools
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Geiger, Matthias; Wirtz, Guido
    Business Process Model and Notation (BPMN) 2.0 process models are used more and more, both in practice as in academia. Although academic research mainly focuses on sophisticated semantic checks and extensions there still exist problems in the basic usage of BPMN. This paper investigates issues in BPMN model serializations which arise as a result of the complexity and inconsistency of the standard document. We present a set of serialization constraints as a starting point for sophisticated compliance checks on serialized BPMN models. Furthermore, these constraints are used to perform an evaluation of current modeling tools. This evaluation reveals that the creation of standard compliant models is still a non-trivial endeavor.

    Can boundary objects mitigate communication defects in enterprise transformation? Findings from expert interviews
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Abraham, Ralf; Niemietz, Hella; Kinderen, Sybren de; Aier, Stephan
    Inappropriate communication is a major threat to enterprise transformations. While enterprise architecture (EA) models may be helpful to support communication, these models are often tailored to the needs of specialists like enterprise architects. Based on empirical data from 12 expert interviews, we analyze how EA models can become boundary objects that span knowledge boundaries and alleviate communication defects among heterogeneous stakeholder groups in enterprise transformations. We contribute a framework that maps six communication defects to three knowledge boundaries and to 12 boundary object properties as a foundation for future EA model design. Our findings also indicate that EA models alone are not sufficient for overcoming communication defects, but that facilitators like architects are needed in addition.

    Cognitive Efficient Modelling Using Tablets
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Stark, Jeannette; Burwitz, Martin; Braun, Richard; Esswein, Werner
    Recently, conceptual modellers have to choose between modeling tools running on tablets or in a common PC environment. This choice has some implications on how cognitive efficient the modeling process is. While using touch input (given on a tablet) eyes and hand are directly coordinated, which supports human gaze behaviour. On the contrary, modelling with a mouse (given in a common PC environment) does not allow direct eye-hand coordination and therefore needs additional effort to coordinate eye and hand. This effect is investigated within a two-group laboratory experiment using BPMN as a modeling language and thus assesses if modeling on tablet is cognitive efficient. Furthermore, we derive assumptions how improve cognitive efficiency of modeling tools.

    Do We Need a Standard for EPC Modelling? The State of Syntactic, Semantic and Pragmatic Quality
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Fellmann, Michael; Bittmann, Sebastian; Karhof, Arne; Stolze, Carl; Thomas, Oliver
    The quality determination of business process models is a complex and demanding task. In literature, a plethora of different quality criteria can be identified and are respectively used by practitioners. The selection of quality criteria depends on the one hand on the respective preferences of the individual modeller. On the other hand, it is prescribed by the modelling language in use, as it has embodied specific criteria e.g. based on its syntax. For the widespread EPC, no comprehensive overview of existing aspects for the evaluation of an EPC model's syntactic, semantic and pragmatic quality exists. With this investigation, we present such an overview and put the identified aspects into a holistic perspective based on the identified and relevant literature.

    Guidelines for Education in Business and Information Systems Engineering at Tertiary Institutions
    (Business & Information Systems Engineering: Vol. 59, No. 3, 2017) Jung, Reinhard; Lehrer, Christiane
    The paper presents guidelines for education in business and information systems engineering (BISE) at tertiary institutions, which were designed by a working group comprising domain experts, both from academia and practice. The guidelines contain the learning outcomes in Bachelor’s and Master’s degree programs, in particular, the key subject-specific, social, and personal skills needed by BISE graduates. Moreover, corresponding occupational profiles, the specific skills required, as well as the essential and typical learning content for BISE education are described. Furthermore, detailed recommendations for the design of Bachelor’s and Master’s degrees curricula and sub-curricula in BISE, business administration, and computer science, respectively, are provided. The presented guidelines serve several purposes. Providing common directions for BISE education is aiming to support personnel in charge of curriculum development and to assist students in program and career choice.

    Human-oriented challenges of social BPM: an overview
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Pflanzl, Nicolas; Vossen, Gottfried
    Social BPM is the practice of actively involving all relevant stakeholders into BPM through the use of social software and its underlying principles. This allows enhancing the correctness, completeness, and usefulness of process models and instances by leveraging the domain and method knowledge of the entire business community. However, the large number and variety of contributors and contributions also results in a number of challenges, which will be examined in this paper.
