CHECK PROCESSING AS AN INFORMATION MANAGEMENT ACTIVITY: CRITICAL REVIEW AND RESEARCH AGENDA

Current management science models fail to adequately recognize that treasury management related to check payments has largely become an information management activity. Check processing operations lack the flexibility to capture information which can be used by treasury managers to make the most effective utilization of check-related funds. This argument is developed by examining the fit between management science models and check processing practice in the U.S. banking industry, as well as at the Federal Reserve Bank, in view of the changes that information technology has wrought and the problems it has the potential to solve. We critique models for inbound and outbound check processing and treasury management for checks, and conclude that models which link check processing and treasury management models hold out significant promise for improving management control.Information Systems Working Papers Serie

Moment method analysis of linearly tapered slot antennas: Low loss components for switched beam radiometers

A Moment Method Model for the radiation pattern characterization of single Linearly Tapered Slot Antennas (LTSA) in air or on a dielectric substrate is developed. This characterization consists of: (1) finding the radiated far-fields of the antenna; (2) determining the E-Plane and H-Plane beamwidths and sidelobe levels; and (3) determining the D-Plane beamwidth and cross polarization levels, as antenna parameters length, height, taper angle, substrate thickness, and the relative substrate permittivity vary. The LTSA geometry does not lend itself to analytical solution with the given parameter ranges. Therefore, a computer modeling scheme and a code are necessary to analyze the problem. This necessity imposes some further objectives or requirements on the solution method (modeling) and tool (computer code). These may be listed as follows: (1) a good approximation to the real antenna geometry; and (2) feasible computer storage and time requirements. According to these requirements, the work is concentrated on the development of efficient modeling schemes for these type of problems and on reducing the central processing unit (CPU) time required from the computer code. A Method of Moments (MoM) code is developed for the analysis of LTSA's within the parameter ranges given

ON THE NEED FOR TOOLS TO SUPPORT SEARCH IN SOFTWARE REUSE: A Perspective Paper Presented to Seer Technologies, Inc.

Software reuse in the presence of a repository and object-based CASE tool is likely to be "biased." Prior research (Banker, Kauffman and Zweig, 1991) showed that a developer will be: most likely to reuse her own objects; somewhat less likely to reuse objects developed by her project team members; and, even less likely to reuse objects stored in the repository, but developed elsewhere in the corporation. This paper characterizes this problem in terms of three familiarity biases: personal bias, project bias and time bias. In the presence of these biases it is appropriate to deploy tools that support the search for software reuse, so that they may be overcome. However, the tools that are chosen or created for this purpose must adequately treat the technical and cognitive fundamentals for individual developers, and recognize the organizational and economic perspectives of a firm that wishes to maximize the business value of its software development activities.Information Systems Working Papers Serie

CUSTOMER ACCESS INFORMATION TECHNOLOGY (CAIT) DEPLOYMENT EVALUATION

Customer access information technology offers great potential benefits to both the organization and its customers. However, managers lack methods for evaluating these technologies and determining whether conditions exist for success. We propose a model from Marketing Science which captures factors influencing the success of a CAIT. The factors include value platform features - features of the CAIT, and location strategy features - features of the environment into which the CAIT is deployed. This model is applied to home banking, providing insights as to types of systems most likely to be successful.Information Systems Working Papers Serie
