The performance impact of business process standardization – An empirical evaluation of the recruitment process
In: Business Process Management Journal (BPMJ), 16(1), pp. 29-56
Category: Publications in scientific journals
AbstractPurpose – The purpose of this paper is to show if business process standardization (BPS) has an impact on business process performance and should be considered as both a valid business process management (BPM) measure and a regular driver of process success.
Design/methodology/approach – An empirical analysis based on data from 156 firms is used to evaluate the hypothesis that process standardization positively impacts business process time, cost, and quality.
Findings – First, the paper proposes a model and empirical operationalization to analyze the impact of process standardization on process performance. Second, empirical analysis shows that BPS has a decisive impact on process performance (R 2 = 61.9 percent). Precisely, there is a significant impact
on process time, cost, and most notably on quality. The results indicate that the impact is strongest in services firms and varies subject to a firm’s strategy type.
Practical implications – The results suggest that BPS should regularly be considered a prime action item and major tool in a firm’s BPM toolbox.
Originality/value – The paper is among the first to empirically show the vital impact of process standardization on performance. For academics and practitioners interested in BPM and the value impact of processes, the results suggest adding process standardization as a regular argument into research on and management of business processes.

Recruiting Trends 2010 - Eine empirische Untersuchung mit den Top-1.000-Unternehmen aus Deutschland sowie den Top-300-Unternehmen aus den Branchen Automotive, Finanzdienstleistung und IT
Category: Working papers
AbstractTrotz der aktuellen Wirtschaftslage erwartet über ein
Drittel der Top-1.000-Unternehmen aus Deutschland
einen Anstieg der Mitarbeiterzahlen im Jahr 2010.
Auch wenn dieser Anteil geringer ist als in den Prognosen
der vergangenen Jahre, lässt das Ergebnis
dennoch auf eine vergleichsweise optimistische Grundstimmung
bei den Studienteilnehmern schließen. Eine
problemlose Realisierung dieses Mitarbeiterzuwachses
wird jedoch schwierig, da die Unternehmen davon
ausgehen, dass 36,6 Prozent der prognostizierten
Vakanzen nur schwer und 4,1 Prozent gar nicht besetzt
werden können. Damit bleibt die Rekrutierung qualifizierter
Mitarbeiter auch im Jahr 2010 eine der größten
Herausforderungen für die Personalbeschaffung deutscher
Großunternehmen. Weitere Herausforderungen
für das Recruiting, wie der sinnvolle Einsatz von Web
2.0-Anwendungen und die Veränderung der deutschen
Hochschullandschaft durch den Bologna-Prozess,
werden ebenso wie das Thema Rekrutierungscontrolling
im Rahmen dieser Studie angesprochen und
analysiert.
Mit Blick auf die Trends der vergangenen Jahre zeigt
sich, dass im Personalmarketing immer mehr Stellenanzeigen
im Internet geschaltet werden. Dabei wurden
in diesem Jahr 62,9 Prozent aller Vakanzen in Internet-
Stellenbörsen und erstmals mehr als 90 Prozent auf
der Unternehmens-Webseite veröffentlicht. Insgesamt
gehen 72 Prozent aller realisierten Einstellungen auf
einen Stellenanzeige im Internet zurück. Im Bewerbungseingang
beläuft sich der Anteil elektronischer
Bewerbungsverfahren (E-Mail- und Formularbewerbung)
auf 65,6 Prozent. Damit folgen die Bewerber der
Präferenz der Unternehmen, von denen 48,2 Prozent
die Bewerbung per standardisiertem Webformular und
28,3 Prozent die Bewerbung per E-Mail bevorzugen.
Die vorliegenden „Recruiting Trends 2010“ sind der
achte Ergebnisbericht dieser jährlich durchgeführten
Studienreihe des Centre of Human Resources Information
Systems (CHRIS) der Universitäten Bamberg
und Frankfurt am Main. Die Studie wurde wie auch
in den vergangenen Jahren von der Monster Worldwide
Deutschland GmbH unterstützt. Die zusätzliche
Befragung der Top-300-Unternehmen aus drei ausgewählten
Branchen sowie die Vorstellung interessanter
Praxisbeispiele im Rahmen von vier Fallstudien helfen,
langfristige Trends in der Rekrutierung deutscher Großunternehmen
besser zu verstehen und entsprechende
Handlungsempfehlungen für das Recruiting von 2010
abzuleiten.

Proposing a theoretical model for IT governance and IT business alignment
In: 42nd Hawaii International Conference on System Sciences (HICSS-42); Waikoloa (HI), USA
Category: Proceedings
AbstractThis paper suggests to extend the view that strateg-ic alignment is a core IT governance issue and post-ulates that considering operational alignment as well offers more precise insights into how governance mechanisms influence business process performance.
Theoretically combining findings from IT value, IT business alignment and IT governance research, we show the tantamount role of top executive support and operational alignment from a governance perspective. Empirical data from 82 firms show, among others, that the impact of IT governance mechanisms on success is mediated by strategic and operational alignment.

AbstractIt is increasingly acknowledged that generating value from IT requires strategic and operational IT business alignment. But it
remains difficult to provide concrete suggestions on what drives alignment in day-to-day business. Thorough process
documentation might enable cross-departmental transparency and thereby serve as an antecedent of operational alignment.
We suggest that business process documentation is a straightforward and actionable antecedent of operational IT business
alignment. Using data from 200 US and German banks it is shown that indeed documentation strongly drives operational
alignment, but surprisingly only in US banks. The implications and avenues for further research on operational alignment are
discussed.

AbstractIT business alignment is widely acknowledged as an important driver for effectively applying information systems in a business context and for increasing the performance of the supported business process. But how does this structural integration of enterprise systems and business processes change when firms outsource the provision of their IT? We empirically compare how the value impact of structural IT business alignment on core financial processes in banks with an internal IT is different from banks that have their enterprise systems outsourced. It turns out that outsourcing substantially changes the ways operational alignment influences business process performance.

Drivers and Inhibitors of SOA Business Value – Conceptualizing a Research Model
In: Proceedings of the 14th Americas Conference on Information Systems (AMCIS 2008); Toronto, Canada
Category: Proceedings
AbstractWhat is the business value of Service Oriented Architecture? Although the SOA paradigm has become quite evident in IS
literature, a comprehensive model of the SOA business value is still lacking. Based on a literature review and on a multitheoretical foundation, drawing on the adoption of innovations literature and on the resource-based view as well as on resource dependency theory, we attempt to develop a research model which captures the business value of SOA, applicable to empirical research in subsequent studies.

Network effects as drivers of individual technology adoption: Analyzing adoption and diffusion of mobile communication services
In: Information Systems Frontiers, 10 (4), pp. 415-429
Category: Publications in scientific journals
AbstractAdoption research has largely ignored the dynamic impact of network effects on technology adoption and diffusion. For example, some technologies become more attractive the more social peers use them as well. But adoption at the same time increases the value for the peers and thereby their adoption decisions as well. Unfortunately, interdependencies like these make adoption and diffusion patterns very complex.
Drawing on network effect theory, we develop an adoption and diffusion model that explicitly considers the role of direct and indirect network effects for individual technology adoption, using mobile commerce adoption as application example. By applying a simulation approach we can exemplify and analyze the fundamental adoption dynamics given rise to by network effects. We thereby propose a way of how to incorporate network effects into adoption research and disclose the role of the technology diffusion lifecycle for individual adoption.

What is process standardization?
In: Proceedings of the 2008 International Conference on Information Resources Management (Conf-IRM); Niagara Falls, Ontario, Canada
Category: Proceedings
AbstractStandards and standardization have
played an important role in the evolution of
information and communication technology. In parts
of the literature on standardization and especially
among practitioners we see a new theme emerge:
business process standards. While there seems to be a
consensus on the desirability of process standards, the
concept has not yet been fully developed, and there is
even less of a clear definition let alone a systematic
understanding of the how and why of its value impact
than with data and communication standards.
In this paper, we suggest a process standardization
construct and the associated value dimensions and
report on a process standardization effort in a large
multinational services firm that reveals how the
theoretical considerations translate into concrete
business value.

AbstractWhat is the impact of business process standardization on BPO success? This paper argues that there is a direct impact of process standardization on BPO success, due to production cost economies, and also an indirect effect via improved contrac-tual and relational governance resulting from better monitoring opportunities and facilitated communication and coordination. This threefold impact of standardization on BPO success is empirically confirmed using data from 335 BPO ventures in 215 German banks.

Password protected due to former publication, please contact the author
AbstractMany business processes are relying on a smooth and flexible IT support. A major finding of IS research is that in order to generate value from IT the complementarities between IT and non-IT resources need to be understood and orchestrated. Especially, IT Business Alignment has been found to be a key driver of both, IT value and business process quality. But how to achieve alignment?
We present the results of a longitudinal case study in a globally active firm from the aerospace industry that shows how a new CEO implemented better business processes by increasing alignment. The results show an enhancing relationship between business and IT resources and concretize key findings from the resource based view. Overall, the case contributes by indicating that business value accrues from a simultaneous change of IS and business practices that was enabled by an increase in the level of IT business alignment.

Decision support for team staffing: An automated relational recommendation approach
In: Decision Support Systems (DSS) vol. 45 (3), pp. 429-447, doi:10.1016/j.dss.2007.05.005
Category: Publications in scientific journals
AbstractSelecting individuals for teams is only rarely supported by Information Systems. Existing systems only consider whether a person has the required technical skills and abilities for a job. Another important aspect is neglected - the match between the person and the team members in terms of interpersonal compatibility.
We present a decision support system based on a relational recommendation approach for providing an automated pre-selection of candidates that fit best with future team members. The relational recommender contributes to theory by proposing an IS-supported relational approach to team staffing and to practice by offering time and cost savings for HR professionals.

Kritische Erfolgsfaktoren in Finanzprozessen - IT-Management und Alignment im Kreditprozess der 1.000 größten Banken in Deutschland
Category: Working papers
Abstract Management Summary
Aufgrund einer Befragung der 1.020 größten Banken Deutschlands (Rücklaufquote 13,3%,
repräsentativ bzgl. Bilanzsumme) zum Kreditgeschäft mit kleinen und mittleren Unternehmen
(KMU) untersucht diese Studie Fragen zum geeigneten Einsatz von IT- und Fachressourcen
und zu kritischen Erfolgsfaktoren im KMU-Kreditprozess. Befragt wurden die für diesen
Geschäftsprozess verantwortlichen Entscheider. Dabei bestätigte sich die Grundvermutung,
dass insbesondere Abstimmungsprozesse zwischen Fachabteilungen und der IT einen wichtigen
Erfolgsfaktor für die Leistung des Geschäftsprozesses darstellen.
*Kreditprozess:* Das betreute KMU-Kreditvolumen der befragten Banken beläuft sich im
Schnitt auf 580,7 Mio. EUR und setzt sich aus 2030 Krediten zusammen. Im Mittel erzielen
die befragten Institute eine Zinsmarge von 1,68% (Zinsmarge = Differenz zwischen
Kundenzinssatz und fristenkongruentem Interbankenzinssatz) für KMU-Kredite guter Bonität.
*IT:* Neben der Kernapplikation zur Unterstützung des KMU-Kreditprozesses nutzen 17,9%
eine elektronische Kreditakte und ein Fünftel ein Workflow-Management-System (bei
weiteren 45% geplant). In allen Teilen des Kreditprozesses werden von der Mehrheit eine
intensivere IT-Unterstützung sowie Funktionserweiterungen bei der Kernapplikation
gewünscht.
*Alignment:* Die Zusammenarbeit der Fachbereiche Markt und Marktfolge wird in der Regel
als gut eingeschätzt und es gibt viele formelle und informelle Beziehungen. Die
Abstimmung zwischen IT- und Fachabteilungen ist dagegen deutlich problematischer. Neben
kaum stattfindender gegenseitiger Beratung zwischen diesen beiden Bereichen sind die IT-
und/oder Geschäftsstrategie entweder nicht explizit vorhanden oder nicht gegenseitig
bekannt. Dabei zeigt sich, dass in Banken mit intensiveren Kommunikationsbeziehungen
zwischen IT- und Fachabteilungen beispielsweise änderungsanfragen deutlich schneller
umgesetzt werden können. Ebenso sehen nur 38,1% Vertrauen und Respekt zwischen beiden
Seiten; diese werden jedoch in der Literatur als wichtige Vorbedingung für erfolgreiche
Zusammenarbeit beschrieben. Entsprechend sind die Fachabteilungen mit der Umsetzung von
Change Requests an der Kreditapplikation unzufrieden und empfinden die Reaktion der
IT-Einheit auf änderungsanfragen als unflexibel (63,9%) und die Umsetzung als langsam
(60,9%) und teilweise auch als nicht effektiv: Nur 29,4% empfinden die Umsetzungen von
Change Requests als nützlich. Wird die Applikation von einem externen Dienstleister
bereitgestellt, so sind diese Bewertungen noch schlechter.
*Prozessqualität:* Die Mehrheit ist tendenziell zufrieden mit dem KMU-Kreditprozess. Es
besteht jedoch insbesondere im Bereich Problemkredite und in der Intensivbetreuung
Verbesserungspotenzial. Im Hinblick auf interne Leistungsparameter ist vor allem die
mangelnde Kenntnis von Prozesskosten ein Problem. Nur etwa ein Viertel der antwortenden
Banken kennt die Kosten für die Bearbeitung eines KMU-Kredites, die bei durchschnittlich
1.357,60 EUR liegen. Wiederum ein Viertel dieser Banken gab sogar Kosten von über EUR
2.000 an. Ebenso ist bemerkenswert, dass Firmenkundenberater im Durchschnitt lediglich
34,5% ihrer Arbeitszeit im direkten Kontakt mit Kunden verbringen. Die Analyse zeigt
weiterhin, dass Banken mit geringer Prozessdurchlaufzeit auch geringere Stückkosten
haben. Die mittlere Durchlaufzeit (Einreichung aller notwendigen Unterlagen durch den
Kunden bis zur Kreditzu- oder -absage) liegt bei einem Standardkredit bei 8,06
Arbeitstagen und bei 14,25 Arbeitstagen für komplexe Finanzierungen. Dabei können durch
eine Verkürzung der Durchlaufzeit um einen Tag im Durchschnitt Kosteneinsparungen von EUR
117 bei Standardkrediten und von EUR 59 bei komplexeren Finanzierungen erzielt werden.
Die Umsetzung eines Change Requests der Art "Hinzufügen eines neuen Datenfeldes" dauert
im Durchschnitt 16,5 Wochen, die Berücksichtigung eines aufgrund regulatorischer Vorgaben
geänderten Arbeitsablaufes durchschnittlich 9,9 Wochen; die Schwankungsbreite beider
Werte ist jedoch recht groß. Dabei ist in Banken mit gutem IT-Business-Alignment die
Reaktionsgeschwindigkeit der IT-Abteilung höher.
*Outsourcing:* Die generelle Einstellung gegenüber der Auslagerung von Teilen des
KMUKreditprozesses ist negativ. Interessanterweise sind Nutzungsintensität der IT,
Automatisierungsgrad der Geschäftsprozesse, Anzahl an Medienbrüchen sowie die
Einschätzung der Kompetenz und Innovationsfähigkeit des IT-Personals davon unabhängig, ob
die IT intern betrieben wird oder ausgelagert wurde. Einzig die Einschätzung der
IT-Flexibilität wird von Banken, die ihre Kernapplikation ausgelagert haben, deutlich
schlechter beurteilt.
*Wettbewerb:* Jede Bank sieht sich durchschnittlich 3-4 Wettbewerbern gegenüber. Speziell
in regionalen Märkten mit einer hohen Anzahl an Wettbewerbern zeigen sich eine hohe
Wettbewerbsintensität und ein niedriger preislicher Handlungsspielraum der befragten
Banken. Im Durchschnitt erreichen die Kreditinstitute in ihrem relevanten Markt einen
Marktanteil von 37,5%.
*Prozessgestaltung:* Auch wenn die Ausgestaltung des Kreditprozesses von den Banken
derzeit nicht als Wettbewerbsfaktor gesehen wird, zeigt die Studie, dass diejenigen
Banken, die dies dennoch tun, höhere Marktanteile haben und zufriedener mit der
Profitabilität ihres Kreditgeschäftes sind. Diese Gruppe zeichnet sich auch dadurch aus,
in den letzten Jahren verstärkt Marktanteile hinzu gewonnen zu haben. Insgesamt zeigt
sich, dass die Kompetenz der Fachseite den höchsten Anteil an einer
überdurchschnittlichen Prozessleistung besitzt, die IT allerdings deutliche Unterstützung
leisten kann. Während es keinen Einfluss der Institutsgröße auf die Prozessqualität gibt,
hat auch die Flexibilität der Fachabteilung einen direkten Einfluss auf die
Wettbewerbsposition. Der folgende Abschnitt bietet einen genaueren überblick über die
Ergebnisse der Studie. Bei Fragen oder Anregungen freuen wir uns auf ihre Rückmeldung

AbstractPurpose of this paper
The goal of this paper is to identify core IT value drivers in firms and to
model them as an IT production function to help disclose and measure the IT
value creation process and to guide managers in seeking adequate ways of employing
the IT resource.
Design/methodology/approach
Based on a critical review of the literature on the resource-based view, an
IT value framework based on the constructs IT capability, resource, and routine
is developed and then formalized as an IT production function.
Findings
Organizational routines are decisive for turning firm resources into an IT capability
and in turn into better business process performance. We show how the IT value
creation process in general and routines in particular can be measured and formalized.
Practical implications
As the interaction between IT and business units is crucial for IT value generation,
or-ganizational routines provide for important knowledge flows that turn firm
resources into value generating capabilities. We propose a concrete method to
measure and evaluate these routines and thereby contribute to making the IT
resource controllable.
What is original/value of
paper
Our main contribution is the identification and analytical formalization of
the role of rou-tines for IT value creation. We show how insights from the resource-based
view, micro-economic theory (Cobb-Douglas/CES production function), and Granovetter's
strength of ties argument can be used to describe, measure, and guide IT value
creation and to develop an IT production function.

The Impact of Operational Alignment on IT Flexibility - Empirical Evidence from a Survey in the German Banking Industry
In: 13th Americas Conference on Information Systems (AMCIS 2007); Keystone (CO), USA
Category: Proceedings
AbstractAlignment and IT flexibility have been found to be crucial for a firm’s long-term success in many indus-tries. This paper investigates how alignment and flexibility are interrelated at an operational level. Based on a survey with Germany’s Top 1,000 banks we show on a business process level that shared knowledge and mutual understanding (as dimensions of alignment) between IT unit and business department have a positive impact on IT flexibility. On the other hand, higher degrees of communication between business and IT units do not correlate with higher IT flexibility.

The Influence of Alignment on the Post-Implementation Success of a Core Banking Information System: An Embedded Case Study
In: 40th Hawaii International Conference on Information Systems; Hawaii
Category: Proceedings
Password protected due to former publication, please contact the author
AbstractThe literature suggests that the success of an information system among others depends on its utilization. In this paper, we argue that operational IT business alignment is an important driver of system usage and thereby of the market success of the supported business process.
Using an embedded case study in four branches, the back office, and the IT department of a retail bank, many findings of the recent alignment literature can be supported. Using a strict business process perspective, we also offer new insights by showing that alignment is important for IS success in operations as well and positively influences post-implementation IS usage. In particular, mutual understanding between the units and shared domain knowledge not only between IT and business but also between different business units supported by the same core IS turned out to be very important factors of IS usage that have so far been neglected.

AbstractAre standardized business processes less risky to outsource? Despite the importance of both areas, neither the outsourcing nor standardization literature has so far offered a conclusive picture of the value of standards to outsourcing. We aim to provide an exploratory first step by suggesting that process standards have a positive impact on business process outsourcing (BPO) risk.
Theoretically drawing from perceived risk theory and the theory of reasoned action we develop a model of BPO risk and empirically show that indeed risk perception is higher for less standardized processes. Using data from 126 German banks, it turns out that financial and performance risks of BPO significantly differ between high- and low-standardized processes and are consistently higher for less standardized processes. While this work is very exploratory and the findings are quite preliminary, they are very encouraging as they indicate promising further research into the value of standards for business processes and outsourcing.

AbstractThe ability to outsource IT has been suggested as a major driver of IT productivity. At the same time, the literature on the business value of IT suggests that IT business alignment and IT flexibility are important drivers for the performance of IT. But what is, then, the impact of outsourcing on these key value drivers? In this paper, we empirically show that firms with internal IT exhibit significantly better IT business alignment and IT flexibility.

Strategies to Boost Standard Diffusion in Communication Networks - Insights from Network Effect Theory
In: Proceedings of the Special Interest Group on Adoption and Diffusion of Information Technology (DIGIT) Pre-ICIS Workshop; Milwaukee, USA
Category: Proceedings
AbstractIT standards are subject to network effects which establish challenges concerning a successful diffusion of standards. A renowned example is a mobile service provider trying to establish a network of customers while potential user often wait until the network is sufficiently large in terms of other users (direct network effect) or content available (indirect effect). Despite the potential benefits to adopters and providers, there is still much uncertainty on the differential impact of direct and indirect network effects on the diffusion of standards and their impact on successful diffusion strategies to establish a user base. Our research questions thus are:
(a) …what are the adoption drivers of IT standards and
(b) …how can providers influence these drivers to develop an installed base?
Based on network effect theory, we propose a formal model that simultaneously considers the different effects of direct and indirect network effects on the diffusion of communication standards. Using com-puter-based simulations we can show that IT providers could exploit the alternating impact of direct and indirect network effects at different diffusion stages to successfully establish an installed base. This has fundamental implications for the provider’s pricing and market strategy.

AbstractWie kann die Ressource IT wertschaffend eingesetzt werden? Auf der theoretischen Grundlage des Resource-based View of IT sowie der Alignment-Literatur argumentieren wir, dass die tatsächliche Nutzung der IT sowie das Zusammenspiel zwischen IT und Fachabteilungen grundlegend für die Leistung von IT-intensiven Geschäftsprozessen sind. Das entwickelte Wirkmodell wird in einer Studie unter den 1.000 größten Banken Deutschlands empirisch untersucht.
Es zeigt sich, dass die Leistung des untersuchten Geschäftsprozesses, wie hypothetisiert, stark von einem Alignment zwischen der IT- und der Geschäftsdomäne abhängt. Ebenso wird deutlich, dass ein bestimmtes Ausmaß fachlicher Ressourcen entscheidend ist und auch eine herausragende IT-Ausstattung und -Unterstützung keine Mängel hinsichtlich dieser fachlichen Ressourcen ausgleichen kann. Die Ergebnisse bestätigen damit wichtige Einsichten der Literatur zu Alignment auch auf Prozessebene und zeigen im Gegensatz zu bestehender Literatur theoretisch wie empirisch, dass der Wertbeitrag der IT nicht ohne Berücksichtigung der Nicht-IT-Fachkompetenz untersucht werden kann.

The Influence of Perceived Risks on Banking Managers' Intention to Outsource Business Processes - A Study of the German Banking and Finance Industry
In: Journal of Electronic Commerce Research (JECR); Volume 7, Number 2, pp. 78-96
Category: Publications in scientific journals [Find it]
AbstractInformation Technology (IT) is a key productive factor in the banking and finance
industry (BFI) as almost the entire production and delivery of services can
in principle be digitized. Driven by cost pressure and new competitors, outsourcing
IT together with the relevant business processes is a promising way to focus
on core competencies and to restructure the corporate value chain.
While there is a rich literature on the risks and benefits of IT outsourcing,
little is known about the next step of business process outsourcing
(BPO) and especially the associated risks. Our main hypothesis is that the perceived
risks associated with BPO strongly influence the intention of managers to outsource
business processes. Based on an empirical survey of BFI managers covering 90%
of the cumulated German BFI balance sheet, it is shown that
- perceived risk does indeed have a significant impact on managers' attitudes
towards BPO and that these attitudes strongly influence the outsourcing decision.
- Financial risks turn out to be a major risk facet, exerting pressure on
banks which decide solely in terms of potential cost savings.
- In addition, the high importance of performance risk requires banks to
invest in sophisticated vendor management.

AbstractStrategic alignment deals with the capability of IT to both shape and support business strategy. It can be interpreted as an organizational learning process that combines business and IT knowledge to support business objectives and can positively affect organizational profitability by creating superior strategies that achieve a competitive advantage. These strategies have to be implemented, because strategies are only effective when they are translated into actions readily. Therefore, in this paper we introduce the concept of operational IT business alignment, reflecting the functional integration at the structural level and representing the link between business and IT structure. Using structural equation modeling and data from 136 banks we show that operational IT business alignment positively impacts dynamic IT and business capabilities and in turn strategic alignment and firm performance.

Social Interaction as Constituting Element of Routines: Incorporating Social Network Analysis into IS research
In: forthcoming in 12th Americas Conference on Information Systems (AMCIS 2006); Acapulco, Mexico
Category: Proceedings
AbstractOrganizational routines known from the Resource-based View (RBV) are considered elementary for IT value creation as they determine the efficiency with which firms transform inputs to outputs.
As routines are socially complex patterns of inter-action, we incorporate findings from the literature on the Resource-based view and Social Network Analysis to disclose the social formation of organizational routines as a constituting element. Our model extends the central findings of the RBV by considering the impact of the social embeddedness of a firm’s employees using Granovetter’s strength of ties argument. The proposed model can be used for a sensitivity analysis regarding the impact of different interaction patterns between and among organizational units on business process performance. The model provides good support for the effects cited in the literature and is illustrated by a case.

AbstractThere is a general consensus among practitioners and researchers alike that IT business alignment improves business performance. Alignment mostly is researched at a strategic level, but has to be implemented in daily operations to be effective. Therefore, in this paper we introduce the concept of operational IT business alignment, reflecting the functional integration at the structural level and representing the linkage between business and IT structure. Using structural equation modeling and data from 136 banks we show that operational IT business alignment positively impacts IS usage and IT flexibility and in turn process performance. Furthermore it is shown that the effect of IT business alignment strongly depends on the type of business strategy a bank follows.

Designing a process-oriented framework for IT performance management systems
In: The Electronic Journal Information Systems Evaluation, (EJISE), Vol. 8 , Issue 3, 219-228
Category: Publications in scientific journals
AbstractIn recent years, control and governance of internal services such as Information Technology (IT) have become quite critical in organisations due to the enormous size of their expenditure. As a result, managers have faced growing pressure to measure the performance of IT departments. Several concepts have been developed during the last few years such as IT governance, IT scorecards, and benchmarking that have been considered by IT and business execu-tives. But surprisingly, a recent study by the IT Governance Institute (ITGI) that covered 335 CEOs and CIOs in 21 countries, reported “while more than 91 percent of executives recog-nize that information technology (IT) is vital to the success of their businesses, more than two-thirds of CEOs are not comfortable answering questions about governance and control over their IT processes.” The study validates that the major problem continues to be “the inadequate view of how well IT is performing” (ITGI, 2004). Hence, decision-makers and stakeholders within private and public companies are insisting that IT executives provide hard facts on mission and IT performance. As such, a promising performance management system is required: setting performance targets, designing efficiency and effectiveness measure, systematically and accurately measuring outcomes, and then using the results for fact-based decision-making.
This paper shows, which concepts and frameworks currently exist to measure the performance of the IT department and its delivered IS services. We discuss how a performance management system might be designed and implemented with the purpose to monitor and improve the IT function within a major financial institution in Europe. Finally, this paper pro-vides lessons learned and some recommendations for further research in the area of IT performance management.

A Unified Economic Model of Standard Diffusion: The Impact of Standardization Cost, Network Effects and Network Topology
In: Management Information Systems Quarterly (MISQ), Volume 30, Issue SPEC. ISS., 2006, pages 489-514
Category: Publications in scientific journals
AbstractThis paper is motivated by the following question: what drives the diffusion of a communication standard and what diffusion results can we expect? Past literature provides many instructive but mostly unrelated answers. Frequent findings are startup problems, penguin effects, and tendencies towards monopoly. But substantial problems in applying the models to concrete standardization problems reveal that the dynamics are probably more complex. Not all networks are ultimately conquered by a single standard once it has attracted a certain number of users. And not all diffusion results are either complete or no standardization.
We address the question of the conditions of particular diffusion behaviors by developing a formal standardization model that captures all fragmented phenomena in a unified approach. Drawing from findings of other research we incorporate the structure of the underlying user network as an important determinant for diffusion behaviors. The approach allows us to disclose varying conditions that generate frequently observed standardization behaviors as special parameter constellations of the model. Using equilibrium analysis and computer simulations we identify a standardization gap that reveals the magnitude of available standardization gains for individuals and the network as a whole. The analysis shows that network topology and density have a strong impact on standard diffusion and that the renowned tendency towards monopoly is far less common. We also report how the model can be used to decide on corporate standardization problems.

AbstractRecommendation systems are widely used on the Internet to assist customers in finding the products or services that best fit with their individual preferences. While current implementations successfully reduce information overload by generating personalized suggestions when searching for objects such as books or movies, recommendation systems so far cannot be found in another potential field of application: the personalized search for subjects such as applicants in a recruitment scenario. Theory shows that a good match between persons and jobs needs to consider both, the preferences of the recruiter and the preferences of the candidate. Based on this requirement for modeling bilateral selection decisions, we present an approach applying two distinct recommendation systems to the field in order to improve the match between people and jobs. Finally, we present first validation test runs from a student experiment showing promising results.

Game Theoretical Analysis of Cooperative Sourcing Scenarios
In: Proceedings of the 39th Hawaii International Conference on System Sciences; Kauai, USA
Category: Proceedings [Find it]
AbstractA possible trend in outsourcing, cooperative sourcing is the merging of similar processes by several firms. For example, several banks could merge their payments proc-esses and the underlying IT to jointly realize economies of scale. But what are conditions of stable outsourcing coali-tions? And how to allocate costs within the outsourcing value web?
In this paper we present a micro economic model for analyzing cooperative sourcing decisions. Using a game-theoretical equilibrium analysis, distribution rules of co-operative sourcing benefits are evaluated and necessary condition for stable sourcing cooperations are identified. We formally prove that only a proportional allocation of costs will regularly lead to stable coalitions. Still, a game theoretic experiment indicates that deciders not knowing about the results are more likely to choose inefficient allo-cations leading to instable sourcing networks.

Using case studies in three branches of a retail bank employing identical information systems, many findings of the alignment literature can be supported. The cases also add new insights by showing that alignment is important in operations as well, and that alignment positively impacts IT usage. Especially mutual understanding between the business units and the IT unit turned out to be the single most important factor of IT usage that resulted from frequent interaction and, as far as the IT unit is concerned, from the business orientation of the IT personnel.

An empirical survey with CFOs

- 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.

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.

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.

Some Economics of Vertical Standards: Integrating SMEs in EDI Supply Chains
In: EM - Electronic Markets (15:4), pp. 313-322
Category: Publications in scientific journals
AbstractDespite the benefits associated with vertical communication standards like EDI or WebEDI, their diffusion among SMEs has failed to a surprising extent. Accordingly, SME integration into value chains is still a critical issue for IS research on standards diffusion. Goal of this contribution is to disclose the reasons for the slow diffusion of EDI and WebEDI among SMEs and to propose concrete solutions. Based on an empirical survey among SMEs in the German office supply industry, economic and technical obstacles to standard diffusion are identified. First, it is shown that EDI and especially WebEDI solutions are simply economically dominated by a widespread practice in SMEs which is using a Fax for business document exchange. Second, as many SMEs do not employ automated material management systems, they lack the necessary technical preconditions for economically viable EDI. Third, based on these findings a concrete EDI solution is delineated that accounts for the economic and technical particularities constraining SMEs. The proposed solution is successfully applied in the office supply industry today and enables SMEs to reap the benefits of bidirectional EDI while avoiding the expensive investments in EDI converter systems that have so far restrained them from participating in vertical standardization.

AbstractIn this paper we present a novel automated recommendation approach to support the selection of individuals to teams. Recent organizational trends show an increasing importance of team-based work structures and more and more companies use this team-focused structure with the hope to increase organizational effectiveness.
Whereas traditional selection systems are focused on finding a match between job requirements and individuals’ abilities, these systems need to be changed in order to reflect the enhanced requirements when selecting individuals to work in teams. This is important as teamwork requires interaction among its members and not just co-action.
Our approach is therefore based on two dimensions. First, people need to be matched to jobs for which they possess the right knowledge, skills and abilities to fulfill all tasks. Second, people need to fit with the other people they are supposed to work with in terms of interpersonal compatibility.
Based on an adapted probabilistic latent aspect model and a trust computational model we present a first prototype aiming to support the systematic selection of individuals to form effective teams.

AbstractThe skills and abilities of a company’s employees are a prerequisite for the enterprise to be innovative. In case the know-how needed to accomplish certain tasks is not available internally or cannot be developed within reasonable time, the company needs to address to the external labor market, e.g. by recruiting experts possessing the skill sets required. However, for rare candidate profiles there exists intense competition on the labor market. Thus, the ability to act within short periods of time when interacting with candidates becomes crucial. In the past, multiple elements of IS support provided many different benefits to improve the recruitment process. However, little research to date exists on what forms of IS support are adapted for what application scenarios within the recruitment arena. Therefore, this paper analyzes how the recruitment process can be optimized and what different levels of E-Recruitment adoption can be identified. We present results from quantitative and qualitative research showing that E-Recruitment functionality can be found in most companies nowadays ranging from isolated solutions for singular activities to integrated end-to-end solutions. Based on these findings we derive managerial guidelines for the management of projects in the E-Recruitment field.

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.

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.

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.

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.

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.

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.

AbstractResearch in information sciences in recent years has dealt
with how to support collaborative work across time,
space and organizational boundaries. However, this
research neglected the question of how information
systems can contribute right at the beginning of virtual
work in the design phase of the team. Team configuration
can be modeled as a two-dimensional matching problem:
individuals need to be brought together (1) with tasks for
which they posses the competencies to carry them out and
(2) with other individuals with whom they are able to
collaborate successfully. It is understood that multiple
dimensions of human as well as social capital and here
especially of trust play an important role in the
underlying decision process. Based on existing research
in multiple fields we develop a framework permitting to
establish successful virtual partnership. We present an
implementation of this framework together with first
promising validation results of the approach chosen.

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
AbstractZunehmender 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.

AbstractEiner Umfrage unter den Top-1.000-Unternehmen in Deutschland (ohne Banken) zufolge verbrauchen die Finanzprozesse in vielen Unternehmen ein Viertel der IT-Bufgets und bieten als typischer Sekundärprozess erhebliches Optimierungspotenzial. Die Autoren entwickeln eine empirisch fundierte generische Financial Chain und identifizieren Ansatzpunkte für Verbesserungen durch ein systematisches Financial Chain Management.
Tatsächlich sind die Verbesseungspotenziale durch interne und externe Vernetzung erheblich. So wickeln zwei Drittel der Unternehmen den Versand ihrer bis zu 4 Millionen Rechnungen jeden Monat über die Post ab. Dabei liegen die Kosten je Rechnung bei durchschnittlich 15,5 EUR, im Gegensatz zu 2 EUR beim elektronischen Rechnungsversand.
Die empirische Untersuchung sowie Fallstudien zeigen Verbesserungspotenziale in der Financial Chain, Einsparungen durch Shared Service Factories und Outsourcing, Wege zu einem Straight Through Processing sowie Ansätze zur Reduktion der Rechnungs- und Reklamationskosten.

AbstractWhile 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.

Strategic Sourcing in Banking - A Framework

Password protected due to former publication, please contact the author
AbstractThe 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.

AbstractDie 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.

Economics of Standards in Information Networks

Category: Book
Password protected due to former publication, please contact the author
AbstractStandards play a prominent role in systems characterized by interaction. In information systems, standards provide for compatibility and are a prerequisite for collaboration benefits. More generally speaking, standards constitute networks. In this work, a standardization framework based on an analysis of deficiencies of network effect theory and a game theoretic network equilibrium analysis is developed. Fundamental determinants of diffusion processes in networks (e.g. network topology, agent size, installed base) are identified and incorporated into a computer-based simulation model. As a result, typical network behaviour (specific diffusion patterns) can be explained and many findings from traditional network effect theory can be described as special cases of the model at particular parameter constellations (e.g. low price, high density). On this basis, solution strategies for standardization problems are developed, and a methodological path towards a unified theory of networks is proposed.

AbstractManagement-Zusammenfassung
Die Verwendung von Informationstechnologie in der Personalbeschaffung bietet Großunternehmen wie auch
kleinen und mittleren Firmen eine Vielzahl von Chancen. Unabhängig von der Unternehmensgröße werden
die Möglichkeiten zu Kostensenkungen im Personalmarketing durch das Schalten von Stellenanzeigen in
Online-Kanälen bereits intensiv genutzt.
Für Großunternehmen rückt zunehmend die effiziente Abwicklung interner Prozesse in den Vordergrund.
Zwei Drittel der befragten Unternehmen stimmen der Aussage zu, dass die Abläufe im Recruiting insgesamt
verbessert werden könnten. Die Nutzung von elektronischen Bewerbungskanälen und Bewerberdatenbanken
leistet hier wertvolle Beiträge. Auch über die interne oder externe Bündelung von Teilprozessen kann eine
drastische Reduzierung von Kosten und Prozesszeiten erzielt werden. Die Fallstudie mit Microsoft Deutschland
zeigt, welche Chancen im Outsourcing von Geschäftsprozessen liegen und wie mit der IT-gestützten, unternehmensübergreifenden
Kooperation mit externen Dienstleistern ein viel versprechender Weg in der Personalbeschaffung
gegangen werden kann.
Neben Kürzungen bei Kosten und Prozesszeiten kann Internet-Technologie helfen, die Passgenauigkeit im
Auswahlprozess zu steigern. Grundlage hierfür ist eine hohe Liquidität an elektronisch verfügbaren, strukturierten,
entscheidungsrelevanten Informationen. Die Fallstudie mit der BMW Group illustriert, wie der Automobilhersteller
dem Ziel der Steigerung der Matching-Qualität mit der Einbindung einer Kompetenzhierarchie
in seine webbasierte Recruiting-Lösung einen bedeutenden Schritt näher gekommen ist.
Auch der Mittelstand hat die Vorteile des Internets für die Personalbeschaffung erkannt. Hier dominiert die
Notwendigkeit, kostengünstig die Reichweite der Personalmarketing-Maßnahmen zu erhöhen. Dabei spielt
die Möglichkeit, potenzielle Kandidaten über Internet-Stellenbörsen auf das eigene Unternehmen und seine
Internet-Präsenz aufmerksam zu machen, eine wichtige Rolle. Werden elektronische Kanäle im Personalmarketing
verwendet, bietet es sich an, in einem nächsten Schritt digitale Bewerbungsverfahren und elektronische
Kommunikationskanäle in der Interaktion mit den Bewerbern zu fördern.
Überblick über die Ergebnisse der Studien
Die vorliegende Untersuchung „Recruiting Trends 2004“ besteht aus zwei Studien. Um einen Überblick über
die Verwendung des Internets und andere Trends in der Personalbeschaffung zu gewinnen, wurden sowohl
die 1.000 größten deutschen Unternehmen wie auch 1.000 Mittelständler befragt. Beide Befragungen wurden
durch Fallstudien mit ausgewählten, auf dem Gebiet der modernen Personalbeschaffung innovativen Unternehmen
ergänzt.

AbstractIn this paper, a method for determining the equilibrium under which firms will cooperate concerning their standardization decisions is developed.
From a theoretical perspective, the network ROI concept is aimed at synchronizing local and global efficiency disturbed by network effects by explicitly determining the value impact of standardization and using it for optimizing enterprise internal decisions concerning standards (i.e. internalizing network effects). From a managerial perspective, ROI based methods are reasonably simple and especially widely accepted. Since the costs of solution determination are considered (by a “virtual instance”), the concept might be applied by a cost center unit responsible for standardization. Methodologically, the solution is developed using basic game theory to understand the discrepancy between local and global efficiency in standardization decisions and later applied to a network of six enterprises as part of an extensive case study.

AbstractWährend in vielen Branchen im Rahmen des Supply-Chain-Management erhebliche Effizienzpotenziale vor allem durch die Orchestrierung der Güter- und Informationslogistik realisiert werden konnten, finden sich bei Finanzprozessen noch ungenutzte Potenziale. Die Financial-Chain, die den Fluss der Finanzströme in und zwischen Unternehmen repräsentiert und ein Viertel der gesamten IT-Budgets verbraucht, ist in vielen Branchen noch wenig optimiert. Zwei von drei CFOs der deutschen Top-1.000-Unternehmen sind entsprechend nicht „zufrieden“ mit ihren Finanzprozessen, und die Hälfte hat bei sich bereits Verbesserungspotenziale identifiziert. Insgesamt ist der Blick auf Finanzprozesse stärker durch die Aufbauorganisation als den eigentlichen Prozessfluss bestimmt.
Das größte interne Optimierungspotenzial wird in den Teilprozessen der Quali-fikation (Identitäts- und Bonitätsprüfung) und Rechnungsstellung gesehen. Allerdings sieht über die Hälfte der CFOs das wesentlich größere externe Optimierungspotenzial in der besseren Verzahnung ihrer Finanzprozesse mit Partnern und Kunden.
Die Verbesserungspotenziale innerhalb der Prozesse der Financial-Chain lassen sich in drei Kategorien einteilen:
- Qualität der Prozesse durch bessere Informationen zur Risikoreduktion
- Dauer bis eine Rechung durch die Kunden bezahlt wird
- Kosten, die bei Bearbeitung einer Rechnung anfallen
Ein durchgängiger elektronischer Fluss der Finanzströme ermöglicht, die Qualität der Prozesse zu erhöhen. So sind beispielsweise alle relevanten Daten zur Qualifizierung der Kunden vorhanden und es sind exakte und schnelle den Kunden betreffende Analysen (Identitätsprüfung, Bonitätsprüfung) durch die zeitnahe Verfügbarkeit von Daten möglich.
Eine Reduzierung des DSOs – Dauer, bis die Kunden ihre Rechungen begleichen (Days-Sales-Outstanding) - stellt eine Kennzahl für die Durchlaufzeit der Financial-Chain dar. So wird der DSO durch eine vermehrte Nutzung interner Daten im Rahmen der Qualifizierung reduziert und ermöglicht es so den Unternehmen, das gebundene Working Capital anderweitig einzusetzen. Ebenfalls wirken verschiedene Zahlungsinstrumente (z.B. Lastschrift) unterschiedlich verringernd oder erhöhend auf den DSO.
Die Kosten können durch einen erhöhten Einsatz der elektronischen Rechnung gesenkt werden. Ebenfalls reduzieren einzelne Eingangskanäle für Reklamationen die Prozesskosten.
Ein bemerkenswertes Problem und gleichzeitig ein wichtiger Lösungsansatz ist die schlechte Dokumentationslage. Nicht einmal jedes vierte Unternehmen hat durchgängig dokumentierte Finanzprozesse, was nach Meinung über der Hälfte der CFOs eine notwendige Vorbedingung zur Erschließung von Optimierungspotenzialen darstellt, sei es durch eigene Shared-Service-Organisationen oder Outsourcing.
Unternehmen, die bereits eigene Erfahrungen mit Outsourcing von Teilen der Financial-Chain gemacht haben (16%), stehen dieser Alternative deutlich positiver gegenüber und schätzen auch das Knowhow des Sourcingpartners viel höher ein als Unternehmen ohne bisherige Outsourcing-Projekte, welche die höchste Prozesskompetenz bei sich wähnen. Ebenso sind Outsourcing-erfahrene Unternehmen positiver in der Beurteilung des Outsourcing von Teilprozessen der Financial-Chain, nur jeder fünfte berichtet von gescheiterten Projekten. Mögliche operative Kosteneinsparungen liegen, bezogen auf die aktuellen Kosten, intern durch Shared-Service-Organisationen (zentrale Prozessbündelung) bei 13,7% und extern durch Business-Process-Outsourcing (BPO) bei 10,3%. Nichtsdestoweniger ist Outsourcing in der Financial-Chain bislang eher die Ausnahme, und es wird für die nächste Zukunft nicht erwartet, dass sich der Trend zur Auslagerung verstärkt.
Wichtige Verbesserungsansätze im Rahmen eines Financial-Chain-Management umfassen eine durchgängige Prozessdokumentation, das Outsourcing von Teilprozessen (z. B. Finanzierung oder Rechnung) an Experten (z. B. Finanzdienstleister) sowie die Möglichkeit, zukünftig große Teile der Financial-Chain an externe Partner (z. B. Banken als Sourcingpartner) auszulagern.

AbstractDie Philosophie des Supply-Chain-Management (SCM) hat durch eine Orchestrierung der Güter-, Finanz- und Informationsflüsse Effizienzpotenziale erschließen können. Während traditionelles SCM erfolgreich vor allem auf die Güter- und Informationslogistik fokussiert, finden sich bei Finanzprozessen noch ungenutzte Potenziale. Dieser Beitrag zeigt auf Grundlage einer empirischen Untersuchung die Integrationsproblematik in der Financial-Chain (FC) bei deutschen Top-1.000-Unternehmen auf. Nicht ausreichend integrierte Systeme sind der Hauptgrund für Rechnungsreklamationen und damit ein vermeidbarer Hauptkostentreiber. Hierauf aufbauend wird skizziert, wie eine skalierbare bedarfsgerechte Integration im Rahmen eines XML-Warehouse realisiert werden kann.

AbstractIn Informationsnetzen wie Intranets, Supply Chains oder EDI-Netzwerken stellen Standards Kompatibilität her und sind damit Grundlage der Realisierung von Kooperationsvorteilen. Standards konstituieren Netzwerke. Entsprechend bilden Entscheidungen über den Einsatz von Standards einen wichtigen Aufgabenbereich des betrieblichen Informationsmanagements.
In diesem Beitrag wird argumentiert, dass die Entwicklung einer hierfür anwendbaren, umfassenden Netzwerktheorie als eine Kernaufgabe der Wirtschaftsinformatik angesehen wird. Ein vielversprechender Rahmen wird in der Erweiterung eines grundsätzlich ökonomisch (nutzen- und gleichgewichtstheoretisch) fundierten Vorgehens um interdisziplinäre Beiträge wie z. B. aus der Soziologie sowie um das Forschungsparadigma der Agent-Based Computational Economics (ACE) gesehen. Damit können insbesondere die institutionelle Einbettung der sozioökonomischen Netzwerkakteure sowie beschränkte Akteursrationalität und damit die komplexen gegenseitigen Abhängigkeiten von Mikro- (Akteur) und Makrostruktur (Netz) berücksichtigt werden.

AbstractThe emerging penetration of IT architectures with XML leads to increasing XML data volumes. Available tools often fail in realizing scalable XML processing for large XML data volumes. This paper introduces Infonyte-DB, a persistent XML Processor that economizes on system resources and allows processing large XML data volumes. Based on concrete application scenarios it is illustrated how Infonyte-DB can be deployed for XML based web services, technical documentation, and mobile information management.

AbstractIn this paper, an analogy between IT firm valuation and IS valuation is used to learn from how investment banking professionals cope with the renowned valuation problem. It becomes clear that theoretically sound approaches like the discounted cash flow might be inappropriate to determine the true value of a software company. Especially for IT valuation, real options approaches are a promising way of capturing the “true” underlying value to new technologies. Unfortunately, as expert interviews reveal, the importance of this approach in investment banking practice is negligible.

AbstractSearching for and selecting qualified partners is a core task in many business contexts.
Empirical research among Germany’s top 1,000 firms discloses that internet-
based platforms are effectively used as a personnel marketing channel but
cannot increase the matching quality between jobs and candidates. Using erecruitment
as an example, we show how the matching quality can be substantially
improved by means of a probabilistic latent aspect model developed in this
paper. The underlying method incorporates findings from collaborative filtering
and hybrid approaches to automated recommendation and is based on a model of
personal attributes derived from research on team building and work psychology.

AbstractResearch problems in ICT networks often comprise coordination problems of information infrastructures and require state-of-the-art methods of coping with complex system dynamics. Especially, relevant economic network analysis is increasingly challenged to transcend “reductionist economic agendas” and incorporate findings from other disciplines. Recent trends of trying to bridge existing theoretical gaps in disciplinary research approaches by integrating the findings of other scientific disciplines reinforce the role of IS in establishing a sound theory of (social, economic) networks.
Based upon efforts towards extending an economic view on networks, in this paper the paradigm of agent-based computational economics is proposed as a possible methodological path towards developing a unified perspective on network research.

Password protected due to future submission, please contact the author
AbstractIn this paper, some of the main results of an interdisciplinary research project on standards are presented and integrated into a single framework of technology diffusion. Based on network effect theory and diffusion theory, we present an agent-based simulation model that extends the traditional economical network perspective by incorporating structural determinants of networks (centrality, topology/density) from sociology and geography and individual decision making on the part of prospective technology users under realistic informational assumptions. Based upon these models, decision behavior in terms of the selection of standards and the diffusion of technological innovations in networks can be described. The model has so far served as both, a tool for developing and evaluating network strategies in practical application like EDI networks or corporate directory service planning as well as for providing theoretical insights into standardization problems and possible solutions.

AbstractIneffiziente Abwicklungsprozesse, die weltweite Beschleunigung der Abwicklungsgeschwindigkeit sowie steigende Transaktionsvolumina machen eine umfassendere Automatisierung des grenzübergreifenden Wertpapiergeschäfts erforderlich. Verschiedene Standards, meist auf der Grundlage von XML, buhlen um die Rolle als globaler bankenweiter Kommunikationsstandard.
Das Ziel des vorliegenden Beitrages ist die Analyse des Status Quo des XML-Einsatzes innerhalb und zwischen Banken sowie der Bedeutung und Akzeptanz der Initiativen zur Entwicklung und Etablierung branchenweiter Standards für ein straight through processing. FpML, FIX, SWIFT und ISO 15022 werden als die bedeutendsten Standards angesehen. Viele Banken sehen bei der XML-Verwendung derzeit noch Probleme in der Dokumentengröße (Bandbreite) und –verarbeitungsgeschwindigkeit, gehen aber ausnahmslos von XML als zukünftigem Datenformat aus. Insgesamt wird aus inhaltlichen wie politischen Gründen ISO 15022 als zukünftig dominanter Standard erwartet.

AbstractNetworks utilizing modern communication technologies can offer competitive advantages to those using them wisely. But due to the existence of network effects, planning and operating cooperation networks is difficult. In this paper, the strategic situation of individual agents deciding on network participation is analysed. A systematic equilibrium analysis using computer-based simulations reveals principal solution scenarios for network agents and shows that network cooperation problems might frequently be not as difficult to resolve as often feared. In particular, strategic situations are identified showing that a majority of individuals might be better off getting the optimal solution from a central principal and that in many cases simple information intermediation can solve the start-up problem notorious in network economics.

AbstractCollaboration is vital for the survival of companies in today’s fast moving economy and,
therefore, finding and matching partners is an important task. This is true for many different
scenarios ranging from companies building consortiums over organizations frequently
staffing project teams to the recruitment of new employees. An empirical survey among the
Top 1000 companies in Germany on state-of-the-art recruitment practices shows that the
Internet is already heavily used to attract and identify large sets of potential partners or
applicants. However, the selection of the most suitable candidates from this pool by
predicting the quality of the resulting partnership is only merely supported by information
technology. Building on existing research in the fields of team building and information
systems, we first outline the enhanced information requirements for online partner matching
compared to partner information currently available on the Internet. Based on this, we then
delineate how recommendation systems can assist in improving matching quality by
incorporating relational information when bringing partners together online.

AbstractNetworks utilizing modern communication technologies can offer competitive advantages to those using them wisely (e.g. enterprises). Besides technical and organizational issues there are prob-lems concerning planning and operating networks due to an asymmetry of costs and benefits among the network agents making the development of internalization strategies difficult.
Goal of this paper is to systematically identify the strategic decision situation of individual agents as a foundation for cooperation strategies aimed at exploiting network benefits.
A systematic analysis of decision errors of agents in networks using computer-based simulations reveals principal solution scenarios and shows that network cooperation problems might frequently be not as difficult to resolve as often feared using comparatively simple strategies.

AbstractThe diffusion of innovations has long been a research domain in IS research. Yet, there is no sound theory nor practice to fully understand the complex mechanisms behind networks of users who are tied together by compatibility requirements as is frequently witnessed in information and communication networks. The goal of this paper is to identify key determinants of the technology battle between WAP and i-mode that is recently raging between German cellular service providers and to propose a possible diffusion path.
By adapting an existing network model of technology diffusion, key influences are identified and incorporated into a computer-based simulation model. In doing so, trade-offs like better presentation quality on i-mode cellular clients vs. higher service costs compared to WAP applications can be modeled to propose a systematic sensitivity analysis of factors influencing the success of the respective mobile technologies and associated services. Not at least, the simulation model supports mobile services providers to customize their prices for a faster market penetration through regarding not only indirect (WAP, i-mode) but also direct network effects (SMS, i-mail) as crucial factors for adopters.

AbstractStandards play a prominent role in systems characterized by interaction. In information systems, standards provide for compatibility and are a prerequisite for collaboration benefits. More generally speaking, standards constitute networks. In this work, a standardization framework based on an analysis of deficiencies of network effect theory and a game theoretic network equilibrium analysis is developed. Fundamental determinants of diffusion processes in networks (e.g. network topology, agent size, installed base) are identified and incorporated into a computer-based simulation model. As a result, typical network behaviour (specific diffusion patterns) can be explained and many findings from traditional network effect theory can be described as special cases of the model at particular parameter constellations (e.g. low price, high density). On this basis, solution strategies for standardization problems are developed, and a methodological path towards a unified theory of networks is proposed.

AbstractElectronic Data Interchange (EDI) has been used in businesses for over 40 years to reduce the costs of document processing. In this paper, we analyze the use of EDI in the European automotive industry depending on company-size and region. Even though EDI is strongly used by the European manufactures and suppliers, our empirical results show a clear trend that future Internet-based solutions for exchanging business documents and to support collaborative supply-chain business scenarios will significantly exceed the current level of EDI.

AbstractAccording to the network effect literature, network externalities lead to market failure due to Pareto-inferior coordination results. We show that the assumptions and simplifications implicitly used for modeling standardization processes fail to explain the real-world variety of diffusion courses in today's dynamic IT markets, and we derive requirements for a more general model of network effects. We argue that agent-based computational economics provides a solid basis for meeting these requirements by integrating evolutionary models from game theory and institutional economics.

The Impact of Outsourcing on IT Business Alignment and IT Flexibility: A Survey in the German Banking Industry In: 12th Americas Conference on Information Systems (AMCIS 2006); Acapulco, Mexico [Protected Download] AbstractThe ability to outsource IT has been suggested as a major driver of IT productivity. At the same time, the literature on the business value of IT suggests that IT business alignment and IT flexibility are important drivers for the performance of IT. But what is, then, the impact of outsourcing on these key value drivers? In this paper, we empirically show that firms with internal IT exhibit significantly better IT business alignment and IT flexibility. |

Cospeaker(s): Wagner, H. Alignment and flexibility in the credit business of german banks In: E-Finance Lab Jour FIxe; Universität Frankfurt AbstractIn the research model presented in this speech, the impact of IT-flexibility on the overall profitability of a bank is investigated. On one hand, IT-flexibility drives (ex ante) flexibility costs for establishing a highly flexible IT-infrastructure (which consist of technical and human capabilities) and lowers (operating) change costs by being able to more easily readjust the IT infrastructure. On the other hand, a higher IT-Flexibility in conjunction with an internal fit (business-IT alignment) fosters internal business process performance in IT-intensive processes. The alignment between both departments is hypothesized to play a crucial role in realizing superior internal performance in order to gain a competitive advantage.
This speech presents results of a quantitative empirical study and several qualitative case studies in the german banking industry and addresses the research question whether flexibility and alignment have a substantial effect on business process performance and assist banks in gaining a competitive advantage. Furthermore, the role of flexibility as a prerequisite of succesfully integrating outsourcing vendors is addressed.

Bridging the Assimilation Gap: A User-Centered Approach to IT Adoption in Corporate HR Processes In: Eleventh Americas Conference on Information Systems (AMCIS 2005); Omaha, NE, USA AbstractThe successful adoption of IT innovation and the attraction of qualified human resources are both crucial for organizational performance. However, there is still surprisingly little research at the intersection of both fields: <i>the adoption, diffusion and infusion of IT within corporate HR processes</i>. This is astonishing as evolving IT support in recent years has substantially transformed HR processes showing attractive optimization potentials. <br><br>In this paper, we apply findings from theory and own qualitative and quantitative research to the recruitment process. We present a stage model for the e-HR field and argue that with changing forms of IT support different theoretical models and constructs need to be applied. Also, as soon as locus of adoption and impact begin to deviate an assimilation gap emerges. We therefore adopt a user perspective and show how HR and IT managers can overcome this gap in order to successfully infuse IT in corporate recruitment processes. |

Cospeaker(s): Franke, J. Sourcingoptionen für IT-Dienstleister in der Financial Chain: Ergebnisse einer Studie zum Financial Chain Management In: T-Systems E-Finance Lab Tagung; Universität Frankfurt AbstractViele Unternehmen haben die umfangreichen Fortschritte der Informations- und Kommunikationstechnologie verwendet, um ihre Primärprozesse und die zugehörige Supply Chain zu optimieren. Erhebliche Effizienzpotenziale findet man demgegenüber bei Finanzprozessen. Auf der Grundlage eines Framework für Financial Chain Management haben wir 2004 eine Umfrage unter den 1.000 größten deutschen Unternehmen (ohne Banken und Versicherungen) durchgeführt, die erhebliche ungenutzte Potenziale und den Bedarf nach zusätzlichen Finanzdienstleistungsprodukten am Markt offen legt.
Ein Beispiel ist die Rechnungserstellung: mehr als 8% aller Rechnungen sind inkorrekt, häufig auf Grund falscher Preisangaben, was wiederum auf nicht oder zu wenig integrierte Systeme zur Preisermittlung und zur Rechnungsschreibung zurückzuführen ist. Doch nicht nur die interne Integration derartiger Systeme ist vonnöten, z. B. um das aufwändige Behandeln von Einsprüchen zu reduzieren. Auch die zwischenbetriebliche Integration zeigt erhebliche Potenziale. Deutsche Klein- und Mittelstandsunternehmen versenden 86% ihrer Rechnungen per gelber Post an ihre Kunden, wie aus anderen Studien bekannt ist. Bei den hier untersuchten Fortune-1.000-Unternehmen beträgt dieser Anteil (immer noch) 67%, wobei insgesamt Durchschnittskosten in Höhe von € 15,5 pro Rechnung anfallen, während elektronisch versendete Rechnungen im Durchschnitt mit € 2 zu Buche schlagen.
Die Studie zeigt weiterhin, dass selten Outsourcing von Finanzprozessen betrieben wird, wiewohl es mit Blick auf eine Fokussierung auf Kernkompetenzen eingesetzt werden könnte. Dabei tendieren die befragten Finanzvorstände zu einer Überschätzung der Qualität ihrer Finanzprozesse und der diesbezüglichen Kompetenzen ihres Unternehmens im Vergleich zu externen Spezialisten, was offenbar eine wichtige kulturelle Barriere zur Auslagerung von Teilen der Financial Chain darstellt. Für einige der Finanzprozesse werden Banken und IT Service Provider als Wunschpartner angesehen, was neue Produkte und neue Märkte eröffnet.
Insgesamt sehen wir ein „Value Chain Crossing“, also das Kreuzen der primären und sekundären Finanzprozesse, als viel versprechenden Ansatz für die nächste Zukunft. Ergänzend zeigen wir erste Ergebnisse unserer Studie mit den deutschen Top 500 Banken zur Zukunft des Kreditprozesses. |

Cospeaker(s): Wagner, H. Modeling the impact of alignment routines on IT performance: an approach to making the resource based view explicit In: 38th Hawaii International Conference on System Sciences (HICSS 38); Hilton Waikoloa Village, Big Island, Hawaii, USA 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.

Cospeaker(s): Keim, T. An Integrated Approach to Online Partnership Building In: 38th Hawaii International Conference on System Sciences (HICSS 38); Hilton Waikoloa Village, Big Island, Hawaii, USA AbstractResearch in information sciences in recent years has dealt with how to support collaborative work across time, space and organizational boundaries. However, this research neglected the question of how information systems can contribute right at the beginning of virtual work in the design phase of the team.
Team configuration can be modeled as a two-dimensional matching problem: individuals need to be brought together
(1) with tasks for which they posses the competencies to carry them out and
(2) with other individuals with whom they are able to collaborate successfully.
It is understood that multiple dimensions of human as well as social capital and especially of trust play an important role in the underlying decision process.
Based on research in multiple fields we develop an approach permitting to establish successful virtual partnerships. We present its implementation together with first promising validation results. |

Financial Chain Management: an Empirical Analysis of Sourcing and Partnering Potentials In: Louisiana State University (LSU); Baton Rouge, USA AbstractWhile 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.

Financial Chain Management and Outsourcing In: IBM Industry Solutions Lab; IBM Research Laboratory Zurich, Switzerland AbstractWhile many firms have used advancements in information and communication technology to optimize their supply chain and primary processes, there is still a substantial efficiency potential associated with financial processes. We introduce our framework for a financial chain management. Based on this, a 2004 empirical survey with the Fortune 1,000 enterprises (non-banks) of Germany showed that substantial efficiency potentials are unused. One example is invoicing. More than 8% of all invoices are incorrect, mostly due to faulty prices. Thus, an internal integration of the systems used for pricing and invoicing can substantially cut down the associated costs of claim management. But integrating the invoicing systems with external partners is also important. German SMEs mail 86% of all invoices to customers. In Fortune 1,000 enterprises it is 67%. Here, overall average costs per invoice are € 15,5 in contrast to € 2 for electronic invoices. Our analysis also shows that while outsourcing of financial chain processes 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 chain redesign and substantial efficiency improvements. It turns out that for some financial processes banks and IT service providers are seen as sourcing partners of choice, establishing a new market potential for these firms. Complementing this work we also present first results of our recent survey with Germany’s Top 500 banks on credit process efficiency and sourcing potentials. |
