- ZeitschriftenartikelApplication of Enterprise Models for Engineering Enterprise Transformation(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Aier, Stephan; Gleichauf, BettinaEnterprise models constitute a valuable basis for enterprise transformation because they usually represent a widely accepted image of an enterprise. Practitioners often put a lot of effort in the creation and maintenance of such models that therefore represent a significant investment. However, so far the information contained in enterprise models is to a large extend ‘dateless’ which means it is hardly used to describe the transformation itself consistently. Therefore we propose a method to systematically derive an enterprise transformation model based on existing models representing enterprise structures at different points in time. The result of the method application is a set of project outlines derived from enterprise models. In order to generalise our approach to a multiperiod transformation model capable of coping with dynamic changes and plan deviations we propose a respective conceptual system. Our research artefact (the method) is finally demonstrated in a case study.
- ZeitschriftenartikelBusiness Process Decomposition - An Approach Based on the Principle of Separation of Concerns(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Caetano, Artur; Silva, António Rito; Tribolet, JoséThe functional decomposition of a business process breaks it down into progressively less granular activities. Decomposition contributes to the modular design of a system, the reuse of its parts and to its overall comprehensibility. But achieving these qualities requires a business process to be decomposed consistently, which implies it is always split into an identical set of activities according to a specific purpose, regardless of the modeller’s and modelling context. This paper describes an application of the principle of role-based separation of concerns to consistently decompose a business process into its constituent atomic activities, thus separating its distinct features and minimising behaviour overlap. An activity is abstracted as a collaboration between role types that are played by entities. The decomposition method successively separates the overlapping roles until an activity is specified as a collaboration of an orthogonal set of role types. The method facilitates the consistent decomposition of a business process and the identification of its atomic activities. The relevance of the method is assessed through a number of scenarios according to the guidelines of design science research.
- ZeitschriftenartikelBusiness Process Extensibility(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 3, 2010) Balko, Sören; Hofstede, Arthur H.M. ter; Barros, Alistair; Rosa, Marcello La; Adams, MichaelVendors provide reference process models as consolidated, off-the-shelf solutions to capture best practices in a given industry domain. Customers can then adapt these models to suit their specific requirements. Traditional process flexibility approaches facilitate this operation, but do not fully address it as they do not sufficiently take controlled change guided by vendors’ reference models into account. This tension between the customer’s freedom of adapting reference models, and the ability to incorporate with relatively low effort vendor-initiated reference model changes, thus needs to be carefully balanced. This paper introduces process extensibility as a new paradigm for customising reference processes and managing their evolution over time. Process extensibility mandates a clear recognition of the different responsibilities and interests of reference model vendors and consumers, and is concerned with keeping the effort of customer-side reference model adaptations low while allowing sufficient room for model change.
- ZeitschriftenartikelConstructing a Semantic Business Process Modelling Language for the Banking Sector - An Evolutionary Dyadic Design Science Approach(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Becker, Jörg; Thome, Irina; Weiß, Burkhard; Winkelmann, AxelThe need to extensively model business processes for multiple purposes (e.g., documentation, compliance management, analysis and optimisation etc.) is of major relevance to banks. Efficiently modelling and automatically analysing business process models not only in a syntactical but also in a semantic way becomes increasingly important in order to save costs during process model construction and achieve additional value from process modelling initiatives. In this article, we introduce a domain-specific semantic business process modelling language (BPML), which supports efficient modelling and semantic analysis needs of banks. We do this by adapting an existing domain-specific BPML from the public sector and applying an evolutionary design science research approach that covers several design science cycle iterations. We triangulate and evaluate the final design science artefact (a new semantic BPML for banks) with the help of a multi-method approach using interviews, round table discussions, document analysis, literature analysis and two in-depth case studies from a specialised bank and a universal bank in the financial sector.
- ZeitschriftenartikelDomain Level Specification of Parameterisable Business Components(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 2, 2010) Ackermann, Jörg; Turowski, KlausCombining software components from different vendors to customer-individual business application systems requires sophisticated techniques to specify the components. If a component can be parameterised, its parameterisation properties must be included in the specification. That is the topic of an ongoing research project. This paper discusses how parameterisation issues can be specified on domain level – that is how to describe parameterisable business terms and business tasks as well as parameterisation effects for a functional expert.

- ZeitschriftenartikelA Framework for Clarifying Service-Oriented Notions - How to Position Different Approaches(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Terlouw, Linda I.; Dietz, Jan L.G.Definitions on Service-Oriented Architecture (SOA) and Service-oriented Design (SoD) are often not clear or even contradictory, which makes it hard to compare the various methodologies. We apply the Generic System Development Process (GSDP), a conceptual framework for developing systems of any kind, and specialise it for service-orientation. Using the resulting Service-Oriented Development Process, we position seven state-of-the art methodologies for service-orientation based on two criteria. One is the coverage of the system development process. The other criterion is the depth in which each of the development phases are dealt with.
- ZeitschriftenartikelHow to Preserve Agility in Service Oriented Architectures - An Explorative Analysis(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 2, 2010) Aier, Stephan; Schelp, JoachimAlthough companies introduced enterprise application integration (EAI) a couple of years ago, the complexity of corporate application landscapes is ever increasing. The current wave of technology being introduced into these application landscapes are service oriented architectures (SOA). Not unlike EAI before the introduction of these technologies is associated with re-use of software components and reaping cost cutting potentials. But when looking at the still increasing complexity of application landscapes following the introduction of SOA, the re-use and cost cutting arguments lead to disappointment. However, SOA offers a great potential to increase corporate agility. In order to gain and preserve corporate agility it is necessary to explicitly manage enterprise architecture. This paper discusses the problems of re-use and cost cutting expectations in SOA and contrasts them with the potentials related to make sustainable contributions to corporate agility. Structures, processes, and instruments to realise these potentials are discussed with reference to a literature review as well as to selected case studies.
