信息技术对金融服务业的影响

信息技术对金融服务业的影响
How Financial Firms Decide on Technology(Abstract)
The financial services industry is the major investor in information technology(IT) in the U.S. economy; the typical bank spends as much as 15% of non-intereste expenses on IT. A persistent finding of research into the performance of financial institutions is that performance and efficiency vary widely across institutions. Nowhere is this variability more visible than in the outcomes of the IT investment decisions in these institutions. This paper presents the results of an empirical investigation of IT investment decision processes in the banking industry. The purpose of this investigation is to uncover what, if anything, can be learned from the IT investment practices of banks that would help in understanding the cause of this variability in performance along with pointing toward management practices that lead to better investment decisions. Using PC banking and the development of corporate Internet sites as the case studies for this investigation, the paper reports on detailed field-based surveys of investment practices in several leading institutions.

1.0 Introduction

　　Information technology(IT) is increasingly critical to the operations of financial services firms. Today banks spend as much as 15% of non-interest expense on information technology. It is estimated that the industry will spend at least $21.1 billion on IT in 1998, and financial institutions collectively account for the majority of IT investment in the U.S. economy. In additon to being a large component of the cost structure, information technology has a strong influence on financial firms operatons and strategy. Few financial products and services exist that do not utilize computers at some point in the delivery process, and a firms'information systems place strong constraints on the type of products offered, the degree of customization possible and the speed at which firms can respond to competitive opportunities or threats.

　　A persistent finding of research into the performance of financial institutions is that performance and efficiency varies widely across institutions, even after controlling for factors such as size(scale), product breadth(scope), branching behavior and organizational form(e.g. stock versus mutual for insurers; banks versus saving & loans). Given the central role that technology plays in these institutions, at least some of this variation is likely to be due to variations in the use and effectiveness of IT investments. While some authors have argued that the value of IT investment has been insignificant, particularly in services, recent empirical work has suggested that IT investment, on average, is a productive investment. Perhaps more importantly, there appears to be substantial variation across firms; some firms have very high investments but are poor performers, while otheres invest less but appear to be much more successful. Brynjolfsson and Hitt found that as much as half the returns to IT investment are due to firm specific factors.

　　One potentially important driver of differences in IT value, and of firm performance more broadly, is likely to be the decision and management peocessed for IT investments. Horror stories of bad IT investment decisions abound. Consider the example of the new strategic banking system(SBS) at Banc One(American Banker 1997). Banc One Corp. and Electronic Data Systems Corp. agreed last year to end their joint development of this retail banking system after spending an estimated $175 million on it. As stated in the American Banker article, SBS"was just so overwhelming and so complete that by the time they were getting to market, it was going to take too long to install the whole thing," said Alan Riegler, principal in Ernst & Young's financial services management consulting division. However, not all the stories are negative. New IT systems are playing a vital role in reshaping the delivery of financial services. For example, new computer-telephony integration(CTI) technologies are transforming call center operations in financial institutions. By investing in technology, more and more institutions are moving operations from high-cost branch operations to the telephone channel,where the cost per transaction is one-tenth the cost of a teller interaction. This IT investment not only reduces the cost of serving existing customers, but also extends the reach of the institution beyond its traditional geographic boundaries.

　　In this paper, we utilize detailed case studies of six retail banks to investigate several interrelated questions:

　　１.What processes do banks utilize to evaluate and manage IT investments?
　　２.How well do actual practices align with theoretical arguments about how IT investments should
　　　 be managed?
　　３.What impact does that management of IT investments have on performance?

How Financial Firms Decide on Technology(Part Two)
For the first question, we develop a structured framework for cataloging IT investment practices and then populate this framework using a combination of surveys and semi-structured interviews. We then compare the results of this exercise with a synthesis of the literature on IT decision making to understanding how practices vary across firms and the extent to which this is consistent with "best practices" as described in previous literature. Finally, we will compare these processes to internal and external performance metrics to better understand which sets of practices appear to be most effective.

　　To make these comparisons concrete, we examine both the general decision process as well as the specific processes used for two recent IT investment decisions :the adoption of computer-based home banking (PC banking), and the development of the corporate web site. These decisions were chosen because they were recent and are related but provide some contrast; in particular, PC banking is a fairly well defined product innovation, while the corporate web presence is more of an infrastructure investment which is less well-defined in terms of objectives and business ownership.

　　Overall, we find that while some aspects of the decision process are fairly similar across institutions and often conform to "best practice" as defined by previous literature, there are several areas where there is large variation in practice among the banks and between actual and theoretical best practice. Most banks have a strong and standardized project management for ongoing systems projects, and formal structures for insuring that line-managers and systems people are in contact at the initiation of technology projects. At the same time, many banks have relatively weak processes(both formal and informal) for identifying new IT investment opportunities, allocating resources across organizational lines, and funding exploratory or infrastructure projects with long term or uncertain payoffs.

　　The reminder of this paper is organized as follows. Section 2 describes the previous literature on performance of financial institutions and the effects of IT on performance. Section 3 describes the methods and data. Section 4 describes the current academic thinking on various components of the decision process and compares that to actual practices at the banks we visited. Section 5 describes the results of our in-depth study of PC banking projects and the summary, Section 6 contains a similar analysis for the Corporate Web Site and discussion and conclusion appear in Section 7
