- KonferenzbeitragBeyond 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, RobertIn 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.
- KonferenzbeitragBPMN 2.0 Serialization - Standard Compliance Issues and Evaluation of Modeling Tools(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Geiger, Matthias; Wirtz, GuidoBusiness 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.
- KonferenzbeitragCan 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, StephanInappropriate 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.
- KonferenzbeitragCognitive Efficient Modelling Using Tablets(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Stark, Jeannette; Burwitz, Martin; Braun, Richard; Esswein, WernerRecently, 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.
- KonferenzbeitragDo 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, OliverThe 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.

- KonferenzbeitragHuman-oriented challenges of social BPM: an overview(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Pflanzl, Nicolas; Vossen, GottfriedSocial 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.
- KonferenzbeitragA hybrid OLAP & OLTP Architecture Using Non-Relational Data Components(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Benker, ThomasRelational database systems are still the first choice for the realization of business application systems. They are used as operational databases to persist business process data or as the basis for data warehouse systems. In recent years, the NoSQL-movement proposed a number of new non-relational data stores because of changing requirements of Web 2.0 applications and related limitations of relational systems. We argue that these new systems can also be used in OLTP- and right-time OLAP-scenarios. We demonstrate how enterprise application systems can be realized based on concepts of the NoSQL-movement. We propose an architecture that enables the deployment of an appropriate data model to a certain business domain and the integration of OLTP- and OLAP-functionality. Components of the architecture are suited to enhance business data with analysisrelevant information and to perform analysis tasks. To demonstrate the application of the architecture and its analytic features, we introduce a short case study.
- KonferenzbeitragOn the cognitive understanding of types in modeling languages(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Linden, Dirk van der; Proper, HenderikWe investigate how enterprise modelers see common types (e.g., actor, event, process) used in most modeling languages in terms of their semantic feature structure (e.g., is human, is material). We hypothesize that modelers have specific interpretations for some of these common types that affect their range of conceptually valid instantiations (e.g., actors should not be instantiated as human things). Based on two exploratory psychometric studies performed with enterprise modeling practitioners and computing science students we discuss the way these typical interpretations affect their $model(ing)$ semantics (e.g., results typically having to be modeled as well-described and non-natural entities, restrictions typically as logical necessities), and what consequences these findings have for modeling languages and the use and creation of models themselves, especially in an inherently collaborative effort like enterprise modeling. We conclude by arguing that insights into these conceptualizations are likely useful and should receive more attention and studies.
- KonferenzbeitragOntology-Based Assistance for Semi-Formal Process Modeling(Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Fellmann, Michael; Zarvic, Novica; Sudau, AnneleneThe construction of semi-formal process models is a difficult task due to the complexity of today's business processes. In this contribution, we devise an ontology-based assistant for semi-formal process modeling. The assistant is intended to support the modeler in creating high quality process models with less time and effort by reusing knowledge captured in a reference ontology. At first, we derive functionalities for such an assistant. We then show how the approach can be implemented and integrated into an existing modeling tool. Finally, we describe an experimental evaluation of the approach.
