- ZeitschriftenartikelConcepts for Modeling Smart Cities(Business & Information Systems Engineering: Vol. 64, No. 3, 2021) Bastidas, Viviana; Reychav, Iris; Ofir, Alon; Bezbradica, Marija; Helfert, MarkusThe rapid increase and adoption of new Information Technologies (IT) in Smart Cities make the provision of public services more efficient. However, various municipalities and cities deal with challenges to transform and digitize city services. Smart Cities have a high degree of complexity where offered city services must respond to the concerns and goals of multiple stakeholders. These city services must also involve diverse data sources, multi-domain applications, and heterogeneous systems and technologies. Enterprise Architecture (EA) is an instrument to deal with complexity in both private and public organizations. The paper defines the concepts for modeling Smart Cities in ArchiMate, guided by a design-oriented research approach. Particularly, the focus of this paper is on the concepts for modeling city services and underlying information systems which are added to the EA metamodel. The metamodel is demonstrated in a real-world case and validated by Smart City domain experts. The findings suggest that these concepts are essential to achieve the Smart City strategy (e.g., city goals and objectives), as well as to meet the needs of different city stakeholders. Furthermore, an extension mechanism allows addressing the alignment of business and IT in complex environments such as Smart Cities, by adjusting EA metamodels and notations. This can help cities to design, visualize, and communicate architecture decisions when managing the transformation and digitalization of public services.
- ZeitschriftenartikelDie Bedeutung des Alignment von IT und Fachressourcen in Finanzprozessen Eine empirische Untersuchung(Wirtschaftsinformatik: Vol. 48, No. 5, 2006) Beimborn, Daniel; Franke, Jochen; Gomber, Peter; Wagner, Heinz-Theo; Weitzel, TimKernpunkteIn diesem Beitrag wird im Rahmen einer empirischen Studie mit den 1.000 größten deutschen Banken gezeigt, wie im Zusammenspiel von Fach-und IT-Ressourcen und dem Alignment beider Bereiche die Geschäftsprozessleistung positiv beeinflusst werden kann. Es zeigt sich insbesondere, dasssowohl IT-Ressourcen als auch fachliche Ressourcen einen positiven Einfluss auf die Prozessleistung aufweisenAlignment als eigenständiger Faktor einen singulären Wertbeitrag aufweistauch eine sehr gute IT Schwächen auf Seiten der Fachabteilungen nicht kompensieren kann und ein Geschäftswertbeitrag durch IT somit auch maßgeblich von Faktoren abhängt, die häufig nicht im Einflussbereich der IT liegen.AbstractImportance of the Alignment of IT and Business Resources in Financial Processes — An Empirical Study How do firms realize business value from deploying IT in business processes? Based on the Resource-based View and insights from recent literature on IT/business alignment, we argue that actual usage and the alignment of IT and business units are important prerequisites for a superior performance of IT-intensive business processes. In this paper, a causal model on the joint impact of IT usage, IT/business alignment and business resources on business process performance is proposed and empirically validated using data from Germany’s 1.000 largest banks.It turns out that the perceived performance of the focal business process, as predicted in the theoretical model, strongly depends on IT/business alignment. The empirical analysis also shows that business resources have a large impact and that even a superior IT cannot compensate business resource deficiencies. The results thereby provide support for important propositions of the literature on alignment from a process perspective and contribute to common knowledge that the business value of IT should not be assessed without evaluating and controlling for business resources as a complementary factor.
- WorkshopbeitragDigitales Kompetenzverzeichnis mit Technologien des Semantic Web(Proceedings of DELFI Workshops 2019, 2019) Konert, Johannes; Buchem, Ilona; Stoye, JonathanKompetenzen, die als Dispositionen zur Bewältigung von komplexen Anforderungen verstanden werden können, sind aufgrund indirekter Messbarkeit und der Abhängigkeit von Handlungskontexten schwer so zu definieren, dass sie maschinell erkannt, verknüpft und auf ihre Ähnlichkeit untersucht werden können. Ein erster Schritt ist die Modellierung und Verfügbarkeit in digitaler Form mittels semantischer Strukturen. Der Beitrag stellt zunächst verschiedene Sichtweisen auf die Modellierung von Kompetenzen vor, um dann für flexible Graphen-basierte Strukturen das Anwendungsszenario des EU Erasmus+ Projektes Open Virtual Mobility (OpenVM) vorzustellen, in welchem nachgewiesene Kompetenzen mittels digitaler Kompetenznachweise auf der Basis des Standards Open Badges ausgewiesen werden. Open Badges verweisen auf die in einem digitalen Kompetenzverzeichnis abrufbaren Kompetenzspezifikationen. Der Fokus liegt im Folgenden auf den Anforderungen an ein solches semantisches Verzeichnis, den gewählten Technologien und dem Umfang des entstandenen Prototyps, der im Rahmen des Projektes OpenVM eingesetzt wird.
- ZeitschriftenartikelReg3DFacePtCd: Registration of 3D Point Clouds Using a Common Set of Landmarks for Alignment of Human Face Images(KI - Künstliche Intelligenz: Vol. 33, No. 4, 2019) Bagchi, Parama; Bhattacharjee, Debotosh; Nasipuri, MitaThe present work proposes a new method Reg3DFacePtCd for registration of point clouds. The key contribution of the present method is that an unknown face in 3D point cloud form is given to the system and is registered to the already existing known 3D face point clouds using a fast 3D face registration method. The novelty of the present technique is that at first the alignment and registration parameters are found out by initially registering eight key points of the unknown source model to that of the known model. Next, the rest of the point clouds of the unknown model are registered to that of the known model using the same parameters found as above. The main method used for alignment is iterative closest point (ICP) using point-based technique followed by registration in the least squares sense. Mainly there are two significant contributions. Firstly, we have developed a new mathematical model facial landmark point based model across poses to obtain the target or the known model to which all the unknown models will be registered. Secondly, a novel way to accelerate point cloud matching by reducing the number of points has been proposed. Using a small number of points necessarily would speed up the registration process but may inculcate errors. So, to determine the registration quality of the fundamental eight key points on which the entire registration process is based, a new robust metric namely ICV (ICP certainty vector) consisting of several key components have been used. Finally, we have addressed several important face registration issues like pre-processing, convergence and quality of registration of the entire facial point cloud based on the eight key points. Extensive experimentation on Frav3D, GavabDB, and the Bosphorus databases on a high-performance computing environment show the novelty and robustness of the method.
- KonferenzbeitragTowards Aligning Business Models with Business Processes: A Tool-based Approach(Modellierung 2020, 2020) Schoormann, Thorsten; Hagen, Simon; Brinker, Jonas; Wildau, Sebastian; Thomas, Oliver; Knackstedt, RalfIn an increasingly dynamic environment, organizations need to be able to constantly adapt their business model. When making decisions in terms of adapting a business model, the operative structures that help to implement these adaptations need to be considered as well. Changes in both layers, the business model as well as the business processes, have immediate impacts on each other, and thus, should be aligned in order to allow more informed decision making. In this article, we report on a research project that explores how business models and processes can be aligned by iteratively building and evaluating a prototypical software platform. Doing this, this study contributes to the design of software that facilitates the alignment of both layers as well as provides a foundation for deriving more advanced knowledge such as in the form of design principles.
- KonferenzbeitragVisual cryptography applied to fingerprint features as a solution for pre-alignment(BIOSIG 2011 – Proceedings of the Biometrics Special Interest Group, 2011) Bringer, Julien; Chabanne, HervéVisual cryptography enables to derive from an image two shares that give separately no information on the original image while leading back to the image by superimposition of the shares. In this work, we apply this technique to fingerprint features for enabling an alignment of a reference and a fresh images. The idea is to use an encrypted share derived from the reference data as a kind of reference grid for pre-alignment of the fresh data on it. Following the principle of visual cryptography, it also ensures a storage protection when data are stored in separate locations.
