Intraday Stock Price Effects of Ad Hoc Disclosures: The German Case
In: Working Paper Series: Finance and Accounting Goethe-University Frankfurt/Main Nr. 145
Category: Working papers [Find it]
AbstractThis paper examines intraday stock price effects and trading activity caused by ad hoc disclosures in Germany. The evidence suggests that the observed stock prices react
within 90 minutes after the ad hoc disclosures. Trading volumes take even longer to adjust. We find no evidence for abnormal price reactions or abnormal trading volume
before announcements. The bigger the company that announces an ad hoc disclosure, the less severe is the abnormal price effect following the announcement. The number of analysts is negatively correlated to the trading volume effect before the ad hoc disclosure. The higher the trading volume on the last trading day before the announcement, the greater is the price effect after the ad hoc disclosures and the greater the trading
volume effect.

The Role of Experience for Outsourcing Evaluation

Category: Publications in scientific journals [Password Protected Download] (Please contact the author)
AbstractHow can outsourcing be used to improve financial processes and what role does managers’
experience with outsourcing play for outsourcing decisions?
An empirical survey with CFOs
of Germany’s Fortune 1,000 firms (non-banks) reveals that
- there are substantial efficiency potentials in the financial chain of many firms,
- outsourcing these secondary processes is still quite rare, and
- prior outsourcing experience of managers has a strong impact on the evaluation of the
competencies of external service providers: an experienced manager is more likely to
appreciate the provider’s skills, someone without outsourcing experience presumes the
higher competencies inhouse.

AbstractWhat are future requirements for ERP solutions for SMEs? The following research paper focuses on identifying possible new interfacial areas between banks and SMEs. New banking services could be embedded into SMEs’ information systems to support their financial processes such as cash management, reconciliation, customer management and asset management. We develop a framework and a methodology for our empirical explorative research. They are intended to be the foundation for investigating both, financial processes within SMEs, as well as firms’ willingness to adopt new services offered by financial service providers. Furthermore, first results from four case studies indicate some promising results. They also show particular problems from granting a bank access to SME-internal systems.

An approach for the Management of Service-oriented Architecture (SoA) based Application Systems
In: Enterprise Modelling and Information Systems Architectures (EMISA 2005); Klagenfurt, Austria
Category: Proceedings
AbstractFlexible business processes are a key success factor for enterprises to succeed in globalised markets. The Service-oriented Architecture (SoA) concept is very well suited to support flexible business processes and application systems because capabilities (in form of services) can be composed in the most efficient way to achieve a high level of agility. However, the management of SoA-founded application systems is often neglected. Thus, we present an approach that enhances the traditional SoA concept by additional management functionality, e.g. monitoring mechanisms and SLA management. As a validation of our concept we introduce WSQoSX, a prototypical implementation based on Web Services.

The Influential Role of Perceived Risks versus Perceived Benefits in the Acceptance of Business Process Outsourcing: Empirical Evidence from the German Banking Industry
In: Working Paper
Category: Working papers
AbstractBusiness process outsourcing (BPO) has been suggested as one of the biggest areas of growth in the outsourcing market. Nevertheless, many organizations are still reluctant to outsource business processes that are part of their core business. In order to help overcome this divergence between expectations and reality, we systematically analyze the factors that form an organization’s attitude towards BPO as well as their intention to adopt BPO. We develop a BPO adoption model which is based on the argument that BPO poses both risks and benefits and that decision makers need to balance both before adopting BPO. The model is tested based on data that was collected in the German Banking Industry. Altogether 218 data points on the perceptions of business managers in the four areas of transaction processing (credits, securities, domestic payments, and foreign exchange/money market) were available for model testing via Partial Least Squares. The results show that the intention to outsource these IT-intensive business processes is strongly influenced by the manager’s attitude towards BPO. Other non-rational factors play a minor role. Only peer influences in the banking industry were found to significantly influence intentions. Around 77 percent of the variations in attitude are explained by perceived risks and perceived benefits. The perceived benefits have a much stronger influence on BPO acceptance than risks. This indicates that risks may be somewhat underrepresented in the adoption process. Moreover, it is instructive to note that the ability to focus on core competencies is the strongest advantage for BPO, followed by quality improvements and cost transparency. Interestingly, anticipated cost reductions have less influence than the previous three factors, and access to better resources plays no role in attitude formation. On the other hand, overall BPO risks are clearly dominated by financial risks. Strategic risks are also important and, to a lesser extent, performance risks, while psychosocial risks and privacy risks are not significant predictors. These findings support the recommendation that providers of BPO services should emphasize risk mitigation proposals in their offerings.

AbstractAuf Grundlage einer empirischen Studie des E-Finance Lab mit den größten 519 deutschen Kreditinstituten zeigen die Autoren, dass
- über die Hälfte der Institute mit den eigenen Kreditprozessen und der Zinsmarge nicht zufrieden ist
- ein Drittel den Anteil der gewinnbringenden Kundenbeziehungen nicht kennt
- nur 7% den gesamten Kreditprozess durch ein einziges System abwickeln und nur 22% der Institute elektronische Kreditakten haben
- Vertriebsmitarbeiter weniger als die Hälfte ihrer Arbeitszeit mit Kunden verbringen.
Outsourcing wird dabei als wichtiger Trend gesehen, aktuell indes zurückhaltend betrieben. Im Rahmen der erwarteten Segmentierung der Bankenlandschaft möchten sich 9 von 10 Banken auf den Vertrieb spezialisieren. Allerdings sind die Bereitschaft zum Fremdbezug von Leistungen und der Vorbereitungsstand gering. So haben erst 46% der Privatbanken Outsourcing-Optionen bewertet, 31% der Genossenschaftsbanken und nur 22% der Landesbanken/Sparkassen.
Das Buch zeigt operationelle Verbesserungspotentiale für alle Teile des Kreditprozesses auf und identifiziert Ansätze für eine bessere Konfiguration der zugrunde liegenden Prozesskette im Spannungsfeld von Eigenerstellung und Outsourcing.

IT Performance Management - Methodology, Metrics and Application
In: 3rd Conference on Performance Measurement and Management Control (EIASM); Nice/France
Category: Proceedings
AbstractAs many organizations search for ways to compete more effectively in today’s ever-growing markets, managers are increasingly focusing on internal services. One internal service function that has especially gained a lot of attention is Information Technology (IT) due to the enormous size of its expenditure. Increasingly, decision authorities within private and public sector companies are insisting that IS executives provide hard facts on IT mission and performance. Key performance indicators, governance structures, and new reference models (e.g. CobiT) are aimed at demonstrating how well the IT department and relating processes perform and improve over time. In this context, “IT governance” has evolved as a challenge to provide a management control system that aims to annul various frequently found disadvantages of uncoordinated decisions, lack of transparency and insufficient alignment between business and IT goals.
Based on a comprehensive analysis of current performance management frameworks, we have designed and deployed an IT management scorecard within a Major European Financial Institution. The paper provides valuable insigths concerning the different implementation steps of IT scorecards and related problems.

The Role of IT Business Alignment for Value Creation: A Multiple Case Study among German Banks
In: Proceedings of the 26th International Conference on Information Systems (ICIS05); Las Vegas, Nevada
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractThe ways in which IT creates business value is a key question in IS research and practice. In this paper, we aim to help reveal the role of alignment between IT and business resources in business value creation. In particular, we propose that the contribution of IT to business process performance should be investigated in the context of actual IT usage, with IT business alignment as a moderating variable. Also, IT flexibility should be explicitly considered. Using five case studies from the German financial services industry based on a causal model of IT business value creation reveals that the process of IT business value creation indeed strongly depends on the alignment between business and IT. But it also turns out that actual presence of business competencies is crucial and that even superior IT cannot compensate for business competency deficiencies.

Category: Chapter in book
AbstractDie vorliegende Arbeit befasst sich mit einem neuen Modellierungs- und Analysekonzept für Geschäftsprozesse, das aus zwei Unternehmenstheorien, der Resource-based Theory (RBT) und der Competence-based Theory (CBT), entwickelt wurde. Das Konzept versteht sich als eine zu den traditionellen, prozessbasierten Darstellungs- und Analysetechniken komplementäre Methode, die das Management bei der strategischen Entscheidungsfindung – z. B. über das Outsourcing bestimmter Teilprozesse – unterstützen soll. Das als „Capability Map“ bezeichnete Konzept bietet einen neuartigen Ansatz zur strategischen Evaluierung der Komponenten von Geschäftsprozessen und erlaubt deren Darstellung als ein Netzwerk von sog. Capabilities. Unter dem Begriff „Capability“ verstehen wir das Leistungsvermögen (materielle und immaterielle sowie intellektuelle Ressourcen) eines Unternehmens, eine gewisse Geschäftsfunktion auf beliebiger Granularitätsebene auszuführen. Die Anwendung der Capability Map auf die Prozesse einer deutschen Universalbank zeigen die Nutzenpotenziale dieses neuen Konzeptes auf.

The Impact of Perceived Risk on the Capital Market's Reaction on Outsourcing Announcements
In: 9th Pacific Asia Conference on Information Systems; Bangkok, Thailand
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractOutsourcing has become a widely accepted option in strategic management which, as every business venture, bears chances and risks. Supplementing the popular area of research on the merits of outsourcing, this paper examines how stockholders rate the corporate sourcing decision with regard to the perceived risk they associate with this transaction. Using event study methodology and multivariate cross-sectional OLS-regression, we analyze a sample of 182 outsourcing transactions of the global financial services industry between 1998 and 2004 in order to investigate the risk-specific drivers of excess returns to shareholders. The analysis studies the impact of risk-specific independent variables which include the transaction size, length, outsourced business functionality, and experience with outsourcing. Our findings indicate that risk-mitigating strategies have significant explanatory power, indicating that capital market’s reaction to an outsourcing announcement might at least partly be forecasted. Results show a positive correlation of market reaction and business process outsourcing of financial services companies. We also find strong evidence indicating that capital markets react positively towards relative large transactions compared to the market capitalization of the outsourcing firm. For service providers our results show that traditional IT-related sourcing projects or insourcing of administrative processes has a significant positive correlation with market reaction.

The Influence of Perceived Risk and Perceived Usefulness on Manager's Attitude Towards Business Process Outsourcing
In: Proceedings of the Eleventh Americas Conference on Information Systems; Omaha, NE, USA
Category: Proceedings
AbstractAlthough the financial services industry is a large buyer of outsourcing services, it still lags behind other industries especially regarding business process outsourcing (BPO). This research in progress asks why. The main hypothesis is that subjectively perceived risk is decisive for senior management's attitude towards BPO. A causal model will be developed, derived from Perceived Risk Theory and a review of the literature on the usefulness of outsourcing. Using the model, the influence of different risk and utility facets on the attitude towards BPO is assessed. The next research step will be an empirical test of the model.

Drivers and Inhibitors for Outsourcing Financial Processes – A Comparative Survey of Economies of Scale, Scope, and Skill
In: Proceedings of the Eleventh Americas Conference on Information Systems (AMCIS 2005); Omaha, Nebraska, USA
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractEconomies of scale, scope, and skill are known to be major drivers or inhibitors for outsourcing business processes. This paper presents a comparative analysis of economies of scale, scope, and skill achievable by outsourcing financial processes in non-banks and banks based on two empirical studies conducted with Fortune 1,000 non-banks and Fortune 500 banks in Germany. It can be shown that industrialization tendencies within the credit business in banks are in parts broader sophisticated than within financial processes of other industries. Credit process managers estimate economies of scale and skill achievable by outsourcing to be higher than chief financial officers do. Furthermore, economies of scope, which inhibit selective sourcing, are evaluated as being less problematic. As a result, the credit process managers’ disposition to outsource (parts of) primary financial processes in banks is higher compared to the CFOs’ attendance to outsource parts of their secondary financial processes in non-banks. In accordance with common knowledge, economies of scale and skill are identified as drivers for outsourcing business processes while economies of scope represent an inhibitor. In contrast to common knowledge, our studies suggest German banks being on the way to industrialization and modularization.

The role of alignment for strategic information systems: extending the resource-based perspective of IT
In: Proceedings of the Eleventh Americas Conference on Information Systems (AMCIS 2005); Omaha, Nebraska, USA
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractThe importance of strategic information systems in the financial industry is documented in many studies. But still there is a virulent lack of frameworks to explain the profit impact of IT in general and to guide firms in exploiting the IT resource as a source of competitive advantage.
By incorporating findings from different research strands on the resource based view (RBV) and the strategic alignment literature we elaborate key concepts potentially leading to a sustained competitive advantage. These concepts are explicitly modeled and integrated into a financial services production function using the well-developed instruments of microeconomic theory. Especially interactions between the IT and business domain are found to be a key success driver. Supported by four case studies from the financial services industry it is shown how IT business alignment positively impacts process quality and in turn establishes a competitive advantage. Our findings suggest that the exploitation of strategic information systems in the sense of achieving a sustainable competitive advantage requires establishing an organizational routine of cross-departmental interaction.

An Architecture for a QoS driven composition of Web Service based Workflows
In: Networking and Electronic Commerce Research Conference (NAEC 2005); Lake Garda, Italy
Category: Proceedings
AbstractIn times of globalisation and internationalisation enterprises have to establish flexible business processes to react to dynamically changing markets and to satisfy sophisticated customers. IT architectures that support the integration of legacy systems as well as the collaboration with business partners are a key success factor for flexible business processes. Thus, we present an approach to support flexible business processes by the means of a Service-oriented Architecture (SoA). Web Services as a realization of a Service-oriented Architecture gain more and more in importance to implement business processes. We address Quality of Service (QoS) as crucial for a sustainable success of Web Service based workflows. Thus, we designed and implemented a Web Service architecture with comprehensive QoS support. The selection of a particular Web Service depends on its QoS properties that must be guaranteed in Service Level Agreements (SLAs). The compliance with such SLAs is monitored by a component of the architecture as well.

AbstractWebservices as a technology to enable distributed business processes gain in importance. However, the support of Quality of Service (QoS) is crucial in this context. Thus, we present an integrated Webservice architecture with comprehensive QoS support. The architecture we introduce in this paper supports the assessment of Webservices to assure that only Webservices will be used in critical business processes that satisfy the requirements defined by the user. The selection and execution of a certain Webservice depends on its QoS-properties that must be guaranteed in Service Level Agreements (SLAs). The compliance with SLAs is monitored by the system as well. Furthermore we introduce a prototypical implementation of our Webservice architecture.

Sourcing, Risk and the Financial Market
In: Proceedings of the 13th European Conference on Information Systems; Regensburg
Category: Proceedings
AbstractOutsourcing has become a commonly accepted alternative of strategic management. But how do stockholders rate the corporate decision to divest parts of the former business? We study the stock market reaction of outsourcing announcements of the global financial services industry, using event study methodology and multivariate cross-sectional regression analysis. We analyze a sample of 162 outsourcing transactions between 1997 and 2004 in order to investigate the drivers of excess returns to shareholders of outsourcers and insourcers in the global financial services industry. The analysis studies the impact of independent variables, the driving factors. Our findings indicate that many of these factors have significant explanatory power, indicating that capital market’s reaction to an outsourcing announcement might at least partly be forecasted. Partnering with experienced service-providers significantly benefits the outsourcer. Evidence indicates that insourcers significantly benefit from large deals and transactions relating to traditional IT processes.

Sourcing von Finanzprozessen – Ein Modell zur simultanen Bewertung von Economies of Scale und Scope
In: Internationale Tagung Wirtschaftsinformatik (WI 2005); Bamberg
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractWährend viele Unternehmen Fortschritte in der IuK-Technologie zur Automatisierung ihrer primären Prozesse, zu einer internen und externen Vernetzung und letztlich zur Neuaufteilung und Optimierung der gesamten Wertschöpfungskette genutzt haben, wurden Sekundärprozesse selten als eigener Optimierungsgegenstand betrachtet. In einer empirischen Studie zu sekundären Finanzprozessen in den 1.000 größten deutschen Unternehmen (ohne Banken und Versicherungen) wird gezeigt, dass vor einer Outsourcing-Entscheidung kulturelle Hürden der Entscheider zu überwinden sind. Es zeigt sich insbesondere, dass die individuelle Outsourcing-Erfahrung der entscheidenden Manager von Bedeutung ist und dass Economies of Scale und Scope getrennt betrachtet und damit mögliche Trade-offs häufig ignoriert werden. Zur Erweiterung der reinen Outsourcing-Entscheidung im Hinblick auf viel versprechende Modelle des kooperativen Outsourcing wird untersucht, wer geeignete Partner für eine selektive Auslagerung von Teilprozessen durch eine Kreuzung der eigenen Wertschöpfungskette mit derjenigen des Partners (Value Chain Crossing) sein können. Aufbauend auf diesen empirischen Ergebnissen wird ein Simulationsmodell vorgestellt, welches insbesondere die simultane Betrachtung verschiedener Einflussfaktoren der Outsourcing-Entscheidung erlaubt.

Integrated Decision Model for Credit Product Outsourcing
In: WIRTSCHAFTSINFORMATIK 47 (2005) 2, S. 109-117.

AbstractThe European banking landscape seems to be evolving from a highly vertically integrated banking landscape into a value network of specialized banks. This can also be seen in the credit product indus-try where consumer credit specialists take over portfolios from other banks. While decision models for IS, operations and production outsourcing are discussed in the literature, we lack a model for credit product outsourcing which reflects the change of risk capital as discussed in the literature about credit sales. In combining these two literature strands, we develop a model to determine whether it is beneficial to internally produce or externally source a credit product.

The Impact of IT On Competitive Advantage: A microeconomic approach to making the resource-based view explicit
In: 13th European Conference on Information Systems; Regensburg
Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractHow can an organization establish an efficient IS resource? Over the years, the resource-based view (RBV) has provided important insights into the value creation by IT. Unfortunately, large parts of the literature suffer from broad and ambiguous constructs that are problematic to validate and difficult to concretely apply. Furthermore, the transmission from IT resources on one side to competitive advan-tage on the other is not yet sufficiently understood. Goal of this paper is to clarify some of the often used constructs and build a framework for the transmission from the endowment with resources to the achievement of competitive advantage.
In this paper, we aim to contribute to this research strand in two ways. First, a model incorporating many isolated findings from the RBV is developed. Reflecting the need for a process view as proposed by large parts of the alignment and strategic management literature, this is integrated into a single process framework of analysis. Second, by developing a microeconomic IT service production function incorporating organizational routines the transmission from IT resource to better business process performance is explicated, allowing simultaneous parameter sensitivity analysis and contributing to making the RBV applicable and open for empirical research.

Die Evolutionsschritte zum E-Enterprise: Standardisierung, Vernetzung und Kooperationsstrategien

Category: Chapter in book
AbstractModerne netzwerkartige Unternehmensformen von Supply Webs über flexible Unternehmensallianzen bis hin zu letztlich völlig dezentralen und hochmodularen Dienstearchitekturen als Grundlage für Ad-hoc-Supply-Chains oder ein „Real Time Enterprise“ erfordern eine gezielte Vernetzung zwischen einer Vielzahl von Akteuren zur systematischen Ausbeutung von Skaleneffekten. Dabei gibt es netzwerkspezifische Koordinationsprobleme, die aus der Existenz von Netzeffekten resultieren und besondere Anforderungen an eine schlagkräftige IT-Governance stellen.
In diesem Beitrag wird gezeigt, dass die Philosophie des „Real Time Enterprise“ technische und kulturelle Herausforderungen an die Unternehmensführung stellt. Eine ökonomische Analyse von Vernetzungsgleichgewichten am Beispiel Straight Through Processing im grenzüberschreitenden Wertpapierhandel verdeutlicht, welche Herausforderungen Vernetzungsprozesse mit sich bringen. Computersimulationen zeigen vielversprechende Resultate bezüglich der Lösbarkeit "klassischer" Netzwerkprobleme wie insbesondere des Start-up-Problems und unterstreichen den Wert moderner Strategien wie insbesondere der Coopetition.

AbstractDie Verflechtung von Industrie- und Handelsunternehmen mit Finanzdienstleistern wächst. Ebenfalls nimmt die Industrialisierung der Finanzwelt stetig zu. Das aus dem Supply Chain Management hervorgehende Financial Chain Management adressiert Fragestellungen der Finanzflüsse in und zwischen Industrie- und Handelsunternehmen sowie Finanzdienstleistern. Um zielgerichtet Verbesserungspotenziale in den Finanzflüssen zu realisieren, spielt die Identifizierung der maßgeblichen Werttreiber eine entscheidende Rolle. Basierend auf einer empirischen Studie unter den 1.000 umsatzstärksten Industrie- und Handelsunternehmen in Deutschland werden exemplarisch für die Financial Chain Werttreiber aufgezeigt. Für die Teilprozesse Qualifikation und Rechnungsstellung zeigt sich, dass eine Reduktion der Prozessdauer den Unternehmenswert signifikant erhöhen kann.

AbstractFinancial institutions are part of the backbone of modern nations in the same way electrical power grids and trans-portation infrastructures are. Therefore, breakdowns of single banks or whole financial centers could have a mas-sive impact not only on the affected banks but also on the entire economy (systemic risk). As financial institutions rely heavily on information technology (IT), this is one of their major risk categories. Despite its importance, the research on identifying and mitigating the operational risks associated with IT is still quite immature in theory and in practice, leaving managers without sound decision support. Based on an overview of relevant threats and their possible impacts, this paper derives requirements for a sound decision support system supporting operational risk management in IT.

Globalization and E-Business Application Adoption and Usage: Comparing Germany in a Global Context

AbstractAfter a certain time lag, the diffusion of information systems and e-business applications among German industries seems to be successful in catching-up leading countries such as Scandinavia or the US. In an empirical survey with 903 firms in four countries, more than one third of all firms responded that the implementation of e-business contributed substantially to improve existing operational processes and to expand markets. Although e-business technologies may be available theoretically in all industries and firms, a sustainable impact on business processes depends on the extent and number of deployed e-business applications. A further prerequisite for efficient usage is the consistent and broad integration of applications. On a macroeconomic level, different economic environments and specific national drivers have a significant influence on the diffusion and resulting impact of e-business applications among the industries analyzed.

Category: Proceedings [Password Protected Download] (Please contact the author)
AbstractThis paper investigates the link between IT and firm performance by combining different theoretical perspectives and emphasizing the role of routines in IT-Business alignment. The basic concept of routines is operationalized and presented in an algebraic form allowing for explicit modeling and using of findings from the literature on the resource based view (RBV) and IT-Business alignment.
How to use IT to gain a sustainable competitive advantage and in turn a plus in firm performance is a key question in IS research. This paper examines the RBV and alignment literature and elaborates the importance of routines in both perspectives. The results show routines are a basic underlying concept to understand the linkage between IT resources and firm performance. This basic concept is operationalized showing the functional relationships known from literature. The paper therefore advances theory and informs practice by combining different theoretical perspectives and making them explicit.

The Impact of Reputation on Supply Chains: An Analysis of Permanent and Discounted Reputation

AbstractIn long-term, recurring contractual relationships, which are common in the B2B-arena, reputation and trust play a crucial role. This analysis investigates the joint impact of reputation and price-based ranking of suppliers on the material flow in the supply chain. Positive reputation proves to be a key factor in reaching dominating market positions, which illustrates the importance of building brand awareness in all stages of a supply chain. Through our simula-tion, it will be observed that the ranking of suppliers by reputation-based choice has a stabilizing effect on the material flow in the supply chain. A strong reputation component in the individual choice stimulates the formation of monopolies, while the discount of reputation imposes a countertendency on this effect. The Bullwhip Effect, another phenomenon that carries a countertendency to the reputation-based monopoly effect, is observed to be even stronger for members of tiers with a high fluctuation of order rates.
