- ZeitschriftenartikelDesigning the Shift from Information Systems to Information Services Systems(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Ralyté, Jolita; Khadraoui, Abdelaziz; Léonard, MichelService-oriented paradigm is emerging as a promising solution to handle enterprise information systems (IS) complexity, interoperability, and evolution issues. However, the shift from a conventional IS architecture to a service-oriented one is not an easy task. Various approaches have been proposed in the literature and most of them deal with either business strategic service design or a technical level IS transformation and migration. There is a need for approaches forming the link between these two levels and designing the information level transformations. In the paper, the concepts of information service and information services system (ISS) are promoted and three different ways to design information services and ISS are proposed taking into account enterprise legacy IS evolution. The three approaches are illustrated with examples taken from industrial projects and case studies.
- ZeitschriftenartikelThe Development and Experimental Evaluation of a Focused Business Model Representation(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Roelens, Ben; Poels, GeertBusiness models (BM) are the central concept to understand the business logic of an organization. Enterprise modeling contributes to the conceptualization of BMs by providing explicit representations. A proper BM representation helps to increase the understanding and communication about the underlying knowledge for the stakeholders within a company. However, the existing enterprise modeling languages have a different and partial focus on the BM concept due to their various backgrounds. This prevents the large-scale adoption of these representations in practice. Therefore a focused BM viewpoint is developed, which explicitly facilitates the understanding about the underlying BM components. To this end, existing diagrams of the value delivery modeling language were adapted to prescriptions of the physics of notations, which is a normative theory for cognitive effectiveness of diagrammatic representations. The effect on the understanding was evaluated by an experiment with 93 master students. The results confirm the research hypothesis that the new BM viewpoint increases the understanding of the modeled BM components.
- ZeitschriftenartikelCapability Driven Development: An Approach to Designing Digital Enterprises(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Bērziša, Solvita; Bravos, George; Gonzalez, Tania Cardona; Czubayko, Ulrich; España, Sergio; Grabis, Jānis; Henkel, Martin; Jokste, Lauma; Kampars, Jânis; Koç, Hasan; Kuhr, Jan-Christian; Llorca, Carlos; Loucopoulos, Pericles; Pascual, Raul Juanes; Pastor, Oscar; Sandkuhl, Kurt; Simic, Hrvoje; Stirna, Janis; Valverde, Francisco Giromé; Zdravkovic, JelenaThe need for organizations to operate in changing environments is addressed by proposing an approach that integrates organizational development with information system (IS) development taking into account changes in the application context of the solution. This is referred to as Capability Driven Development (CDD). A meta-model representing business and IS designs consisting of goals, key performance indicators, capabilities, context and capability delivery patterns, is being proposed. The use of the meta-model is validated in three industrial case studies as part of an ongoing collaboration project, whereas one case is presented in the paper. Issues related to the use of the CDD approach, namely, CDD methodology and tool support are also discussed.
- ZeitschriftenartikelCrossing the Line: Overcoming Knowledge Boundaries in Enterprise Transformation(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Abraham, Ralf; Aier, Stephan; Winter, RobertEnterprise transformations are fundamental changes in an organization. Such changes typically affect different stakeholder groups (e.g., program managers, business managers) that exhibit a significant diversity regarding their members’ knowledge, goals, and underlying assumptions. Yet, creating shared understanding among diverse stakeholder groups in transformations is a main antecedent for success. The paper analyzes which properties of enterprise architecture models contribute to syntactic, semantic, and pragmatic capacities which helps to create shared understanding among stakeholder groups involved in enterprise transformation. The differences among stakeholder groups are assessed through the lens of knowledge boundaries, and enterprise architecture models are assessed through the lens of boundary objects. A research model is developed and empirically tested that describes which boundary object properties are required to overcome three progressively complex knowledge boundaries – syntactic, semantic, and pragmatic. The findings show which boundary object properties contribute to a respective capacity needed to overcome each of the three knowledge boundaries. Specifically, the results show that for (1) a syntactic capacity, concrete and modular enterprise architecture (EA) models are helpful; (2) a semantic capacity, visual EA model properties are relevant, and (3) a pragmatic capacity, broad stakeholder participation is conductive.

- ZeitschriftenartikelCapturing Enterprise Data Integration Challenges Using a Semiotic Data Quality Framework(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Krogstie, JohnEnterprises have a large amount of data available, represented in different formats normally accessible for different specialists through different tools. Integrating existing data, also those from more informal sources, can have great business value when used together as discussed for instance in connection to big data. On the other hand, the level of integration and exploitation will depend both on the data quality of the sources to be integrated, and on how data quality of the different sources matches. Whereas data quality frameworks often consist of unstructured list of characteristics, here a framework is used which has been traditionally applied for enterprise and business model quality, with the data quality characteristics structured relative to semiotic levels, which makes it easier to compare aspects in order to find opportunities and challenges for data integration. A case study presenting the practical application of the framework illustrates the usefulness of the approach for this purpose. This approach reveals opportunities, but also challenges when trying to integrate data from different data sources typically used by people in different roles in an organization.

- Zeitschriftenartikele3service: A Critical Reflection and Future Research(Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Razo-Zapata, Iván S.; Gordijn, Jaap; Leenheer, Pieter; Wieringa, RoelCommercial services are of utmost importance for the economy. Due to the widespread use of information and communication technologies, many of these services may be delivered online by means of service value networks. To automate this delivery, however, issues such as composition, integration, and operationalization need to be addressed. In this paper, the authors share their long-term vision on composition of service value networks and describe relationships with fields such as cloud computing and enterprise computing. As a demonstration of the state of the art, capabilities and limitations of e3service are described and research challenges are defined.
