CASE STUDY OF ELECTRONIC BANKING AT MERIDIAN BANCORP

The paper illustrates âbusiness value linkage impact analysisâ, a new method for measuring the business value of information technology (IT), in the context of a case study of electronic banking operations at Meridian Bancorp, a large commercial bank. Management science models were constructed to gauge the impact of automated teller machines (ATMs) on branch teller labour productivity and retail deposit market share, and the potential for substitution of labour by ATMs is shown. Econometric estimation of the models yielded the following results: the efficiency of teller labour was found to decline in the presence of a branch ATM; a bank's ATM network decision was shown to be an important determinant of the relative size of the retail deposit market it could capture in south-east Pennsylvania; membership in the regionally dominant MAC ATM network leveraged retail deposit market share when a clear majority of local branches and ATMs were members of a regionally smaller, competing network: and high-density ATM deployment did not lead to increases in the overall size of the deposit market.Information Systems Working Papers Serie

THE BUSINESS CASE FOR AUTOMATING SOFTWARE METRICS IN OBJECT-ORIENTED COMPUTER AIDED SOFTWARE ENGINEERING ENVIRONMENTS

This paper makes the business case for automating the collection of software metrics for gauging development performance in integrated computer aided software engineering (CASE) environments that are characterized by an object-oriented development methodology and a centralized repository. The automation of function point analysis is discussed in the context of such an integrated CASE environment (ICE). We also discuss new metrics that describe three different dimensions of code reuse -- leverage, value and classification -- and examine the p,ossibility of utilizing objects as means to estimate software development labor and measure productivity. We argue that the automated collection of these software metrics opens up new avenues for refining the management of software development projects and controlling stra-egic costs.Information Systems Working Papers Serie

AUTOMATED SOFTWARE METRICS, REPOSITORY EVALUATION AND SOFTWARE ASSET MANAGEMENT: NEW TOOLS AND PERSPECTIVES FOR MANAGING INTEGRATED COMPUTER AIDED SOFTWARE ENGINEERING (I-CASE)

Automated collection of software metrics in computer aided software engineering (CASE) environments opens up new avenues for improving the management of software development operations, as well as shifting the focus of management's control efforts from "software projectâ to "software assets" stored in a centralized repository. Repository evaluation, a new direction for software metrics research in the 1990s, promises a fresh view of software development performance for a range of responsibility levels. We discuss the automation of function point and code reuse analysis in the context of an integrated CASE (I-CASE) environment deployed at a large investment bank in New York City. The development of an automated code reuse analysis tool prompted us to re-think how to measure and interpret code reuse in the I-CASE environment. The metrics we propose describe three dimensions of code reuse -- leverage, value and classification -- and we examine the value of applying them on a project and a repository-wide basis.Information Systems Working Papers Serie

QUANTIFYING THE BUSINESS VALUE OF INFORMATION TECHNOLOGY: AN ILLUSTRATION OF THE 'BUSINESS VALUE LINKAGE' FRAMEWORK

Senior management's ability to gauge the business value of investments in information technology (IT) has been seriously hampered by a lack of analytic tools to conduct sound performance assessment. In this paper, we present a conceptual framework called a "business value linkage" that is used to represent the processes by which the direct outputs of an IT are transformed within the firm and its operating environment into enhanced revenues, reduced costs and new strategic opportunities to increase market share. Utilizing appropriate modeling and econometric methods, we illustrate our approach by analyzing several hard-to-measure aspects of the business value of automated teller machines (ATMs) in retail electronic banking. The results show that the hardest to measure impacts in some cases can have the greatest business value.Information Systems Working Papers Serie

FACTORS AFFECTING SOFTWARE MAINTENANCE PRODUCTIVITY: AN EXPLORATORY STUDYl

Systems developers and researchers have long been interested in the factors that affect software development productivity. Identification of factors as either aiding or hindering productivity enables management to take steps to encourage the positive influences and to eliminate the negative ones. This research has explored the possibility of developing an estimable model of software development productivity using a frontier estimation method. The approach taken is based upon output metrics for the entire project life-cycle, and includes project quality metrics. A large number of factors potentially affecting software maintenance productivity were included in this initial investigation. The empirical analysis of a pilot data set indicated that high project quality did not necessarily reduce project productivity. Significant factors in explaining positive variations in productivity included project team capability and good system response (turnaround) time. Factors significantly associated with negative variations in productivity included lack of team application experience and high project staff loading, The use of a new structured analysis and design methodology also resulted in lower short term productivity. These preliminary results have suggested a number of new research directions and have prompted the data-site to begin a full scale data collection effort in order to validate a model of software maintenance productivity
