    Enterprise architecture as an instrument of strategic control
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Hartmann, Beate
    Enterprises compete in high dynamic and fast changing markets. Reacting quickly and flexibly to market changes is a crucial competitive advantage for an enterprise. Therefor premises of strategic planning and achievement of strategic goals have to be controlled permanently and in a systematic way. Strategic control which is part of strategic management monitors premises of the corporate strategy and the environment of the enterprise in order to evaluate whether the strategic positioning is still appropriate or whether the strategy has to be adopted due to changes in constraints. This paper shows how the enterprise architecture of an enterprise can be used as an instrument of strategic control. Strategic control is characterized by a high demand on information. Hence one needs to know where needed information is to gather. Enterprise architecture which is enriched by results and information of strategic management process is a helpful instrument in delivering information respectively the source of gathering information used in strategic control. In particular for each enterprise architecture layer a proposal is given how strategic control can be supported.

    Some guidelines for the conception of domain-specific modelling languages
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Frank, Ulrich
    While the potential prospects of domain-specific modelling languages (DSML) are undisputed, the design of a DSML faces specific challenges that have raised only little attention so far. They relate to the boundaries between a DSML and corresponding models as well as to the question how specific a DSML should be. Addressing these challenges does not only contribute to the development of meta modelling methods, it also relates to judging the economics of a DSML. This paper suggests guidelines to support typical decisions that occur with the design of a DSML. They mainly concern the level of abstraction a potential language concept should be defined on. The guidelines are not intended to serve as recipes for design, but rather to improve the transparency of design decisions.

    Understanding IT-management and IT-consulting teaching as product-service system: application of an engineering model
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Boehm, Matthias; Stolze, Carl; Thomas, Oliver
    In this research-in-progress paper we conceptualize the teaching of IT-Management and IT-Consulting as a hybrid package of products (resources) and services (teaching). This understanding offers a new perspective on teaching approaches and creates new opportunities for all stakeholders. Following a wellestablished procedure model for product-service systems (PSS) engineering, we derive the customer requirements to the hybrid package. Than a product model is developed. Based on these findings, an Education Integration Platform Solution (EIPS) is prototypically designed. Finally, a conclusion and outlook are given.

    Process model verification with SemQuu
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Fellmann, Michael; Thomas, Oliver
    In this contribution, we present an overview of our ongoing work in developing an integrated tool support for semantic process model verification. We present some of the requirements and insights gained by the implementation of a platform for semantic process model verification. The platform is based on OWL and SPARQL and provides for a user-friendly way of semantic model verification. First empirical evaluations have been very promising and confirm that the tool can be used to effectively query and verify semi-formal process knowledge.

    Introducing a co-creation perspective to service business models
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Zolnowski, Andreas; Semmann, Martin; Böhmann, Tilo
    Due to the growing importance of services for many companies and the resulting transformation of product based business models to service based business models, the paper focuses on the link between business models and services. For this purpose the business model canvas of Osterwalder is adapted to address the shortcoming relating to co-creation of extant business models.

    Developing a cloud provider selection model
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Repschläger, Jonas; Wind, Stefan; Zarnekow, Rüdiger; Turowski, Klaus
    Recently, a growing development and use of Cloud computing services has been observed. Especially modeling cross-organizational cooperation and the respective provider comparison are gaining importance. Despite initial positive results, it is challenging in theory and practice to find an appropriate provider matching the individual requirements. Moreover, the comparison process is complicated by a number of new entrants as well as offers of non-transparent services, which sometimes differ significantly. Due to the lack of adequate possibilities to compare and classify Cloud providers we are presenting in this paper a provider independent classification model for Infrastructure as a Service (IaaS). For this purpose, the target dimensions for Cloud Computing from a customer perspective were defined, based on expert interviews, an international literature review and a Cloud provider market (IaaS and hosting) analysis.

    Modeling choreographies: BPMN 2.0 versus BPEL-based approaches
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Kopp, Oliver; Leymann, Frank; Wagner, Sebastian
    Choreographies capture the collaboration aspects between two or more processes. Explicit choreography notations have been included in the upcoming version 2.0 of the Business Process Model and Notation language (BPMN 2.0). This paper presents a first evaluation of the choreography modeling capabilities of BPMN 2.0 and presents a summary of the evaluation of BPEL-based approaches. The result is that BPMN 2.0 does not support reference passing and is tightly tied to technical configurations.

    Towards automated financial process auditing: aggregation and visualization of process models
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Mueller-Wickop, Niels; Schultz, Martin; Gehrke, Nick; Nüttgens, Markus
    Internal and external auditors face an enormous amount of financial entries in accounting information systems. For many reasons - like legal regulations - a process-oriented view of these entries is urgently needed in order to understand the way financial entries are produced in accounting information systems and to infer the underlying processes. Traditional modeling languages focus on processes but pay no regard to the financial value-flows. Furthermore, automated process retrieval approaches only reconstruct single process instances, which need to be aggregated for reasons of comprehensibility, simplification and clearness. The paper wants to close this gap and integrate the process with the accounting perspective followed by an aggregation of single process instances. As a result we present a visualization form capable of integrating the financial view with process flows. In this way, auditors are able to trace how balance sheet items have been produced in the system during the fiscal year.

    Applying soft systems methodology in enterprise architecture creation workshops
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Nakakawa, Agnes; Bommel, Patrick van; Proper, Erik
    Lack of effective involvement of stakeholders is one of the main drawbacks of enterprise architecture initiatives. Ongoing attempts to overcome this involve using Collaboration Engineering to develop a collaboration process that enterprise architects can execute to facilitate collaborative sessions with stakeholders during architecture creation. However, a field study evaluation of this process revealed that it offered inadequate support for stirring vigorous and rigorous discussions during activities that required organizing and assessing problem or solution aspects that resulted from brainstorming activities. Since Soft Systems Methodology (SSM) helps to structure rational thinking about messy situations, its techniques can be adapted to supplement the design of the collaboration process with support for triggering discussions and creating a shared understanding and vision among stakeholders. This paper therefore presents a script that shows how this can be done, and discusses its evaluation in a real case.

    Enriched service descriptions using business process configurations
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) AbuJarour, Mohammed; Awad, Ahmed
    Service descriptions play a crucial role in Service-oriented Computing (SOC), e.g., for service discovery, service selection, service composition, etc. However, it has been observed that service providers – the main source of service descriptions - typically release poor service descriptions, i.e., mostly technical-oriented descriptions. Several approaches have been proposed to tackle this problem by enriching poor service descriptions with additional information from other sources, e.g., communities or domain experts. In this work, we propose a novel approach to generate additional information about web services based on the configurations of their consuming business processes. For instance, we can extract annotations and context information for web services based on the configurations of their consuming business processes. In this paper, we introduce our proposed approach and its architecture based on the open-source online modeling platform Oryx and our public service registry Depot.
