Beiträge zur Industrialisierung von Finanzprozessen durch Web Services – Externes Straight Through Processing für Master-KAGen

In: Information Management & Consulting 19 (2004) Sonderausgabe, S. 64-72

Category: Publications in journals

Abstract

Zunehmender Kostendruck sowie Liberalisierungen in der Finanzwelt wie insbesondere das Zulassen der Auslagerung von Dienstleistungen für Kreditinstitute durch das BaFin haben Outsourcing erneut zu einer zentralen CIO-Aufgabe gemacht. Für institutionelle Anleger bedeutet dies neue Gestaltungsmöglichkeiten und hat die Master-Kapitalanlagegesellschaft (Master-KAG) zu einem der spannendsten Trends im Asset Management gemacht. Doch vor der Realisierung der mit dem Aufbrechen und Neugestaltung der Finanzwertkette verbundenen Potenziale ist die Herausforderung zu meistern, die komplexen Interaktionen zwischen allen Beteiligten durch flexible und effiziente IuK-Architekturen zu unterstützen und damit eine nachhaltige Wettbewerbsposition in diesem schwierigen Wachstumsmarkt aufzubauen.

In diesem Beitrag werden nach einer kurzen Einführung in das Master-KAG-Konzept zunächst betriebswirtschaftliche und technische Herausforderungen wie z. B. STP-Fähigkeit (Straight Through Processing) diskutiert und konkrete Lösungsanforderungen abgeleitet. Anhand einer Fallstudie mit der Allianz Dresdner Asset Management, Spezialfonds-Marktführer mit 12,5 Mrd. Master-KAG-Fondsvermögen, wird eine konkrete web-service-basierte Umsetzung vorgestellt. Insbesondere durch die mit Web Services einhergehende Möglichkeit, unterschiedliche Beteiligte sehr einfach in einen gemeinsamen Prozess einzubinden kann analog zu früheren Erfahrungen mit EDI im Supply Chain Management ein Beitrag zu einer Industrialisierung von Finanzprozessen erfolgen.

A Real Options Approach to Outsourcing Decisions under Uncertainty

In: EFL Quarterly; Frankfurt

Category: Other publications

Abstract

The financial services industry is operating in highly volatile markets. To consider the impact of uncertain market environments on in- and outsourcing decisions, we introduce a real options based decision support model. We apply the model to an IT infrastructure outsourcing decision and determine - based on cost savings resulting from outsourcing and option values accounting for uncertainty - different “trigger” output volumes which indicate if in- or outsourcing is preferable. Finally we show that the model can also be transferred to sourcing decisions of transaction based business processes like clearing and settlement of securities.

Financial Transaction Outsourcing - an attribute-based view

Category: Miscellaneous

Abstract

This paper analyses the relevant criteria that a process qualify to be characterized as an “on-demand process”. The election of some process attributes shall help suppliers to transform their applications into "on-demand services". By developing a list of the characteristic attributes of an “on-demand process” a qualification for singular/compound sourcing to a service platform is identified and validated against an example of a payment process, in particular of financial transaction processing, which is modelled with UML (Unified Modeling Language). Hence it is shown a possible way to transform processes into "on-demand applications"

A Framework for Classifying the Operational Risks of Outsourcing

In: Proceedings of the Eighth Pacific-Asia Conference on Information System (PACIS); Shanghai

Category: Proceedings [Password Protected Download] (Please contact the author)

Abstract

Operational risk and outsourcing are two major topics on today's agenda of top executives, especially in the banking industry. This paper introduces a framework to classify operational risk in outsourcing in a way that generates quantifiable output for measurement purposes. The authors developed a matrix system that deploys a catalogue of sources of risk and a mu-tually exclusive yet exhaustive system of measurable impact areas. It is shown that this framework adds to the understanding of operational risk as its application enhances trans-parency through the transformation of often vague risk descriptions to quantifiable risk indi-cators. An overview of the current IS literature on risks in outsourcing combined with a criti-cal assessments of deficiencies for transparent risk classification serves as a input for the classification process.

Benchmarking Financial Chain Efficiency – the Role of Economies of Scale for Financial Processes

In: Proceedings of the Eighth Pacific-Asia Conference on Information System (PACIS 2004); Shanghai

Category: Proceedings

Abstract

While many firms have used advancements in information and communication technology to optimize their supply chain and primary processes, there is still a substantial efficiency poten-tial associated with financial processes. A main hypothesis is that an industrialization of the financial chain by standardizing as well as internal and external systems integration can offer great efficiency potentials due to economies of scale. In this paper, based on an empirical survey with Fortune 1,000 CFOs, a benchmark of the in-voicing process in these firms reveals to what extent economies of scale can explain the sub-stantial efficiency discrepancies.

Abstract

While many firms have used advancement in information and communication technology to optimize their supply chain and primary processes, there is still a substantial efficiency potential associated with financial processes. In this paper, a conceptual framework for a systematic financial chain management is developed. Based on this, an empirical survey with the Fortune 1,000 enterprises of Germany shows that while outsourcing of the financial chain is still quite rare it can be successfully used to focus on core competencies. A main finding is that CFOs tend to systematically overestimate the quality of their financial processes and especially the firm’s competencies compared to external experts. This is an important cultural barrier to a value redesign that could offer substantial efficiency improvements.

Make, Buy or Share - Combining Resource Based View, Transaction Cost Economics and Production Economies to a Sourcing Framework

In: WIRTSCHAFTSINFORMATIK 46 (2004) 3

Category: Publications in scientific journals

Abstract

In this paper a sourcing decision framework is developed combining the resource based view transaction cost economics and production economies. The combined theories are used to provide a sequential application of the main arguments of resource based view, transaction cost theory and production cost theory to decide on making, buying or sharing an activity. A further key contribution of this paper is the introduction of share as an alternative to make or buy. Share means the bundling of resources between competitors and reflects the importance of cooperation between competitors as a way of improving the efficiency of production. The developed framework regards IT as a portfolio of activities and can be used to evaluate which IT activities should be produced internally and whether cost savings expected from IT outsourcing may be realizable.

Strategic Sourcing in Banking - A Framework

In: Proceedings of the 12th European Conference on Information Systems; Turku, Finnland

Category: Proceedings [Password Protected Download] (Please contact the author)

Abstract

The banking landscape in Europe and Germany has a polypolistic market structure with an average vertical range of integration of 80%, implying high process redundancies. Accumulating processes for standardized products is one way to achieve efficiency improvements. “Smart sourcing” can change the production mix of banks lead to a concentration of processes. A challenge is the lack of consistent frameworks for the banking industry to systematically support the sourcing decision process. In this paper, drawing on the resource based view and transaction cost economics it is shown that, in addition to a make or buy decision, co-operation between competitors should be included into a sourcing analysis as the third alternative. To support the decision on making, buying or sharing an activity, a quantitative analysis of each activity of the banking value chain is necessary. We propose an analysis framework based on a generic banking value chain. Since the recent literature mostly focuses only on the outsourcers’ case, a formalized model is developed to consider both the objective function of the out- and the insourcer. Since the market might restrict sourcing options, as there may be no providers of relevant activities, it can be shown that “sharing” as part of a co-opetition concept instead of buy or make can be a way to break up the value chain. The framework thus supports decision makers to approach an optimal degree of vertical integration for both market sides.

Financial-Chain-Management: Ein generisches Modell zur Identifikation von Verbesserungspotenzialen

In: WIRTSCHAFTSINFORMATIK 46 (2004) 2

Category: Publications in scientific journals [Password Protected Download] (Please contact the author)

Abstract

Die Finanzprozesse in vielen Unternehmen bieten als typischer Sekundärprozess erhebliches Optimierungspotenzial. Eine empirische Untersuchung bei den 1.000 größten deut-schen Unternehmen (ohne Banken, Versicherungen) zeigt, dass die Finanzprozesse ein Viertel der IT-Budgets verbrauchen, allerdings 2 von 3 CFOs mit diesen nicht zufrieden sind. Die in diesem Beitrag entwickelte generische Financial-Chain bietet Ansatzpunkte für Verbesserungen in der Financial-Chain.

• Neben den Teilprozessen Qualifikation, Finanzierung, Preisfindung, Absicherung, Reklamation und Zahlung bietet die Rechnungsstellung das höchste einzelne Verbesserungspotenzial.
• 28% aller Rechnungen werden begründet reklamiert. 83% aller Reklamationen beruhen auf Preisfehlern. Eine interne Integration der Preis- und Rechnungsstellungssysteme kann die hiermit verbundenen erheblichen Kosten einsparen helfen.
• Deutsche KMUs versenden im Durchschnitt 86% ihrer Rechnungen per Post, deutsche Großunternehmen (im Geschäftskundenbereich monatlich knapp 70.000) 67%. Dabei liegen die Kosten je Rechnung bei den Großunternehmen bei durchschnittlich € 15,5, im Gegensatz zu € 2 beim elektronischen Rechnungsversand.

In Analogie zu dem güterwirtschaftlich geprägten Supply-Chain-Management zielt das Financial-Chain-Management auf die Erschließung der durch interne und externe Prozessintegration möglichen Verbesserungspotenziale bei Finanzprozessen.
