The promise of immutable documents to make it easier and less expensive for consumers and producers to collaborate in a verifiable way would represent an enormous progress, especially as companies strive for establish service contracts which are based on the flow of many small transactions using machine-to-machine communication. The blockchain technology logs these data, verifies the authenticity and make them available for service offers. This work deals with an architecture enabling to setup order processing between consumers and produceers using blockchain. In this way, the technical feasibility is shown and the special characteristics of blockchain production networks will be discussed.
Im Anschluss an eine theoretisch fundierte und zugleich praxisnahe und umfassende Darstellung des gesamten Event-Marketing und -Management untersucht Gerd Nufer die bislang noch wenig erforschte Wirkungsweise des innovativen Kommunikationsinstruments und geht dabei vertiefend auf das Zustandekommen eines Imagetransfers von einem Event auf eine Marke bzw. ein Unternehmen ein. Abschließend werden dauerhafte Markenerlebniswelten als aktuelle Weiterentwicklungen des Event Marketing vorgestellt. Das Buch bietet eine theoretisch fundierte und zugleich praxisnahe, umfassende Darstellung zum gesamten Event-Marketing und -Management. Darüber hinaus untersucht Gerd Nufer die bislang noch wenig erforschte Wirkungsweise des innovativen Kommunikationsinstruments und geht dabei vertiefend auf das Zustandekommen eines Imagetransfers von einem Event auf eine Marke bzw. ein Unternehmen ein. Abschließend werden dauerhafte Markenerlebniswelten als aktuelle Weiterentwicklungen des Event-Marketing vorgestellt.
Purpose of the research paper is to illuminate the subject of assortment policy in the German fashion e‐commerce market. A short literature review is conducted in order to set up a system of characteristics to contemplate assortments on a strategic level. In a second step, structured observations are conducted to quantitatively analyze and compare the assortments of the leading online fashion retailers within Germany. Based on literature, the following characteristics for a classification of assortments can be identified: assortment structure, assortment size, assortment width, assortment depth, assortment consistency and rotation, price level, quality mix, fashion degree as well as the mix of private labels and manufacturer brands. Furthermore, the results of the empirical analysis show that there are currently five leaders within the nalyzed market: Amazon, Otto, Zalando, Baur and About You. Among these five market leaders, Amazon positions itself as a retailer that not only offers an enormous assortment size, but also the lowest entry prices as well as the broadest price dispersion. Through the development of the system of characteristics for assortment analysis and the examination of the current market environment, the findings of this paper contribute to the current state of the art in both theoretical and practical aspects.
Anhand von drei empirischen Studien zeigt Christina Kühnl, wie Unternehmen ihren Innovationsprozess optimieren bzw. wie sie die Adoption einer Innovation in ihrer Organisation sicherstellen können. Dabei vergleicht sie die Erfolgsfaktoren von Produkt- und Dienstleistungsinnovationen unter Berücksichtigung nichtlinearer Effekte, identifiziert unternehmensinterne Erfolgsfaktoren und verdeutlicht, welchen Einfluss das soziale Umfeld auf die individuelle Adoptionsentscheidung ausübt.
Die Lage der öffentlichen Haushalte ist aufgrund der Finanz- und Wirtschaftskrise seit geraumer Zeit angespannt. Bereits während des Bundestagswahlkampfs sowie nach dem Wahlsieg der christlich-liberalen Koalition im Jahr 2009 gab es eine hitzige Debatte über die Vereinbarkeit von Steuersenkungen und nachhaltigen öffentlichen Finanzen. Im vorliegenden Beitrag wird die Frage der Finanzierbarkeit von Steuererleichterungen durch zukünftiges Wirtschaftswachstum diskutiert. Auf Basis aktueller Daten und modelltheoretischer Simulationsberechnungen wird ein wirtschaftspolitisch gangbarer Weg zur Umsetzung des Koalitionsvertrages aufgezeigt.
Maintainability assurance techniques are used to control this quality attribute and limit the accumulation of potentially unknown technical debt. Since the industry state of practice and especially the handling of service- and microservice-based systems in this regard are not well covered in scientific literature, we created a survey to gather evidence for a) used processes, tools, and metrics in the industry, b) maintainability-related treatment of systems based on service orientation, and c) influences on developer satisfaction w.r.t. maintainability. 60 software professionals responded to our online questionnaire. The results indicate that using explicit and systematic techniques has benefits for maintainability. The more sophisticated the applied methods the more satisfied participants were with the maintainability of their software while no link to a hindrance in productivity could be established. Other important findings were the absence of architecture-level evolvability control mechanisms as well as a significant neglect of service-oriented particularities for quality assurance. The results suggest that industry has to improve its quality control in these regards to avoid problems with long living service-based software systems.
To bring a pattern-based perspective to the SOA vs. microservices discussion, we qualitatively analyzed a total of 118 SOA patterns from 2 popular catalogs for their (partial) applicability to microservices. Patterns had to hold up to 5 derived microservices principles to be applicable. 74 patterns (63%) were categorized as fully applicable, 30 (25%) as partially applicable, and 14 (12%) as not applicable. Most frequently violated microservices characteristics werde Decentralization and Single System. The findings suggest that microservices and SOA share a large set of architectural principles and solutions in the general space of service-based systems while only having a small set of differences in specific areas.
Digital Enterprise Architecture allows multiple viewpoints on a company’s IT landscape. To gain valuable information out of huge amounts of operational data, it is indispensable to have both an understanding of the operations architecture and an engine capable of managing Big Data. The mechanism of understanding huge amounts of data is based on three main steps: collect, process and use. The main idea is focused on extracting valuable information out of Big Data to make better design decisions. The Elastic Stack is an open-source solution to comfortably and quickly handle Big Data scenarios.
Enterprise Governance, Risk and Compliance (GRC) systems are key to managing risks threatening modern enterprises from many different angles. Key constituent to GRC systems is the definition of controls that are implemented on the different layers of an Enterprise Architecture (EA). As part of the compliance aspect of GRC, the effectiveness of these controls is assessed and reported to relevant management bodies within the enterprise. In this paper we present a metamodel which links controls to the affected elements of an EA and supplies a way of expressing associated assessment techniques and results. We complement the metamodel with an expository instantiation in a cockpit for control compliance applied in an international enterprise in the insurance industry.
The unprecedented acceleration in the dynamics of economic development and its dependence on global interactions makes predicting the future especially difficult. Nevertheless, an examination of long-term trends provides an opportunity to begin a discussion about what reality could await us tomorrow and how we want to deal with it. With this food-for-thought paper, the member institutes of the Fraunhofer Group for Innovation Research wish to present a selection of the trends that are destined to have a significant impact on innovation systems in the period leading up to 2030. Based on these trends, the paper derives theses for innovation in the year 2030 and describes the resulting tasks for business, politics, science and society.
