PublicationApplying Design Research Artifacts for Building Design Research Artifacts: A Process Model for Enterprise Architecture Planning(Springer, 2010-06-04)
;Zhao, J. LeonEnterprise architecture (EA) describes the fundamental structure of an organization from business to IT. EA as a practice as well as a research topic has been around for several years. However, existing methods largely neglect the existence of time which is essential in order to systematically approach EA planning. The article at hand builds a process model for EA planning as a de-sign research artifact. We therefore use another more general design research artifact a method for process engineering in order to systematically build our proposed planning process. From a design science research (DSR) perspec-tive we demonstrate, how elements of the DSR knowledge base can be applied to create new DSR artifacts and how DSR might build a toolbox as it is availa-ble in other mature engineering disciplines.Type: conference paperVolume: LNCS 6105Scopus© Citations 11 -
PublicationProcess Performance Management - Identifying Stereotype Problem Situations as a Basis for Effective and Efficient Design Research(Springer, 2010-06-04)
;Zhao, J. LeonJust recently many organisations get involved with process performance management (PPM). It appears, however, that PPM initiatives confront organisations with multi-faceted and complex challenges that call for a detailed problem analysis before any solution is eveloped. In this paper we introduce two patterns for identifying stereotype problem situations in design research (DR) and apply one to the field of PPM. The application gives detailed insights into typical PPM problem situations and illustrates the usefulness of our approach.Type: conference paperVolume: LNCS 6105Scopus© Citations 4 -
PublicationA Methodology for Content-Centered Design of Ambient Environments(Springer, 2010-06-05)
;Janzen, Sabine ;Zhao, J. LeonThe design of ambient environments does not depend on technical issues exclusively but also on social aspects. There are several design specifications for ambient environments and corresponding development principles, a design method should address. In this paper, we review design methodologies concerning the coverage of existing design principles and their applicability for ambient environments. Because unprecedented, we introduce a methodology for Content-Centered Design of Ambient Environments (CoDesA) and apply this method in parts to an ambient bath environmentType: conference paperVolume: LNCS 6105Scopus© Citations 11 -
PublicationSystematization of Maturity Model Extensions(Springer, 2010-06-04)
;Lahrmann, Gerrit ;Marx, Frederik ;Zhao, J. LeonIn order to identify and explore the strengths and weaknesses of particular initiatives, managers in charge need to assess the maturity of their efforts. For this, a wide range of maturity models has been developed, but there is no detailed methodical guidance how to extend these models. Therefore, we present a systematization of maturity model extensions.Type: conference paperJournal: Lecture Notes in Computer Science (LNCS)Volume: 6105Scopus© Citations 36 -
PublicationSystematic development of business-driven requirements - using next-generation EIS design as an example(Springer, 2010-06-04)
;Marx, Frederik ;Zhao, J. LeonDespite many improvements to IT support for executives, they still complain that executive information systems (EIS) bear little relevance to their management task and fail even more to accommodate their working style. This indicates that business issues should more strongly drive requirements for next-generation EIS. The article contributes to such an EIS design by systematically developing requirements criteria that are more business driven than the state-of the-art. To do so, requirements lists of EIS, structural models of user satisfaction and technology acceptance are evaluated with criteria derived from the requirements engineering discipline. The findings show a dual gap: as the rigor of the models increases, they become less relevant for practice. In comparison, the requirements lists emonstrate relevance, but do not evidence strong rigor. To bridge this gap, this article applies the principle of economic efficiency to balance scientific rigor with relevance for practice. The findings should lead to better next-generation EIS design and should also be applicable to IS in general.Keywords: requirements engineering, next-generation executive informationsystems (EIS), principle of economic efficiencyType: conference paperVolume: LNCS 6105Scopus© Citations 8 -
PublicationRelevance through Consortium Research? Findings from an Expert Interview Study(Springer, 2010-06-04)
;Zhao, J. LeonThe Information Systems (IS) community is discussing the relevance of its research. Design-oriented IS research is considered a promising approach since it combines practical relevance and scientific rigor. Only limited guidance, however, is available for the researcher to gain access to and exchange knowledge from the practitioners’ domain. This is surprising insofar as the IS “ecosystem” is under change and research and innovation largely takes place in the practitioners’ community. Consortium research addresses the issue of getting access to and exchanging knowledge from the practitioners’ community. It supports the development of artifacts and is characterized by close cooperation between the university and its partners in all stages of the design-oriented research process, practical validation of research results with partner companies, and a focus on the practical benefits of the research, with all research activities being funded by the consortium partners. The research question posed in this paper is what consortium research contributes to design-oriented IS research against the background of the aforementioned phenomena. The paper presents the findings from an expert interview study among professors of the German-speaking IS community in Europe.Type: conference paperVolume: LNCS 6105Scopus© Citations 16 -
PublicationUse Cases for Business Metadata - A Viewpoint-Based Approach to Structuring and Prioritizing Business Needs(Springer, 2010-06-04)
;Stock, Daniel ;Zhao, J. LeonBusiness metadata plays a crucial role in increasing data quality of information systems (IS) especially in terms of data believability, ease of understanding, and accessibility. Despite its importance business metadata is primarily discussed from a technical perspective, while its business value is scarcely addressed. Therefore, this article aims to contribute to the further development of existing design approaches by explicitly accounting for the use cases of business metadata. In the course of this article a conceptual framework of use cases is developed, which can be applied in identifying the respective informational requirements a business metadata system needs to satisfy. The framework is structured along the stages of data processing: data consumption, data staging, and data production. A banking case is presented that demonstrates how this conceptual framework has successfully been applied in practice.Type: conference paperVolume: LNCS 6105 -
