Measuring the Efficiency of Service Delivery Processes: With Application to Retail Banking Journal of Service Research
Do Better Customers Utilize Electronic Distribution Channels: The Case of PC Banking
Firms are increasingly implementing electronic distribution strategies to augment existing physical infrastructure for product and service delivery. However, to date there has been little systematic study on how these distribution channels affect customer profitability. In this study, we explore the revenue enhancement potential for electronic delivery in retail banking by comparing customers who utilize personal-computer based home banking ("PC Banking) to other bank customers. Our results, based on case studies and detailed customer data from four institutions, suggest that while PC banking customers appear to be more profitable, most of the differences are due to unobservable characteristics of these customers that were present before PC banking was adopted. Demographic characteristics and changes in customer behavior following the adoption of the product account for only a small fraction of the overall differences. We conclude that, at least to date, the primary potential value of the product is in the retention of high value customers rather than cost savings or incremental sales. Our results also suggest that it is important to distinguish behavioral changes from pre-existing customer characteristics when evaluating the impact of added electronic delivery channels.
Measuring Aggregate Process Performance Using AHP
When one undertakes a benchmarking study, it is quite typical to collect performance data on a set of business processes from a variety of organizations. While one can compare efficiency on a process-by-process level, how can one compare the overall efficiency of one organization versus another using this process-level data? This note presents a methodology that combines tournament ranking and AHP approaches to create a ranking scheme that deals explicitly with missing data and ties in the tournament scheme.AHP, Benchmarking, Process Efficiency
Projections onto Efficient Frontiers: Theoretical and Computational Extensions to DEA
Data Envelopment Analysis (DEA) has been widely studied in the literature since its inception in 1978 and is a key analytical technique used in Wharton's performance analysis for retail delivery systems. The methodology behind the classical DEA, the oriented method, is to hold inputs (outputs) constant and to determine how much of an improvement in the output (input) dimensions is necessary in order to become efficient. The authors extend this methodology in two substantive ways. First, a method is developed that determines the shortest projection from an inefficient DMU to the efficient frontier in both the input and output space simultaneously, and second, introduces the notion of the "observable" frontier and its subsequent projection. The observable frontier is the portion of the frontier that has been experienced by other DMUs, and thus the projection onto this portion of the frontier guarantees a recommendation that has already been demonstrated by an existing DMU or a convex combination of existing DMUs. A numerical example is used to illustrate the importance of these two methodological extensions.
Process Variation as a Determinant of Service Quality and Bank Performance: Evidence from the Retail Banking Study
Conventional wisdom in retail banking states that firm performance is dependent on higher average process performance. This paper refutes conventional wisdom and provides empirical evidence, which demonstrates that low process variation contributes significantly to firm performance. More specifically, this paper examines the effect of process variation, caused by process variability, on service quality and financial performance, as measured by customer satisfaction and price-to-earnings ratio. This paper estimates process variation and reveals large variation in rocesses, reflecting large variation in firm strategy and process design. The data is from the
Effective Call Center Management: Evidence from Financial Services
Call centers are quickly becoming the major point of contact for serving customers and generating new revenue in a variety of industries. No where is this growth in the importance of call centers more apparent than in the financial services industry. This paper presents the results of a survey of the management of call center operations at major financial service firms. The results clearly indicate the importance of human resource management practices and technology in creating high-performance call center environments.
Performance in Consumer Financial Services Organizations: Framework and Results from the Pilot Study
Financial services comprise over 4 percent of the gross domestic product of the United States and employ over 5.4 million people. By offering vehicles for investment of savings, extension of credit and risk management, they fuel the modern capitalistic society. While the essential functions performed by the organizations that make up the financial services industry have remained relatively constant over the past several decades, the structure of the industry has undergone dramatic change. Liberalized domestic regulation, intensified international competition, rapid innovations in new financial instruments and the explosive growth in information technology fuel this change. With this change has come increasing pressure on managers and workers to dramatically improve productivity and financial performance. This paper summarizes the first year of a multi-year effort to understand the drivers of performance in financial services organizations. Financial services are the largest single consumer of information technology in the economy, investing $38.7 billion dollars in 1991 (National Research Council, 1994). While this investment has had a profound effect on the structure of the industry and the products it provides, its effect on financial performance of the industry remains elusive. Why this "productivity paradox" (Brynjolfsson and Hitt,1993) exists is an important part of this project. The authors describe the differences in productivity in services from manufacturing. In the service world, the consumer co-produces the product with the firm, ofte nadding labor to the creation of the service. In addition, the scope of the service enterprise typically is quite vast, with components of the service production process being both producers and deliverers of the service. In addition, the quality of the services provided is forever changing. Thus, the authors suggest that productivity gains from human resource improvements or technology investments may not show up in standard performance measures, but may rather be used to improve the quality of the service provided. What appears to be a stagnation in productivity may actually be an increase in value delivered to the customer. Delivering value to the customer may provide the institution with sales opportunities and much needed information about the institution's customer base. The pilot survey conducted by the authors examines the relationship between technological advancement and the relational part of service delivery by studying time spent with the customer in relation to technological sophistication and time spent on the entire delivery process. The authors adopt the view that processes are the central "technology" of an organization. As with any technology, the process must be maintained. After a process has reached its useful life, it should be scrapped or rebuilt. Thus, the authors suggest that researchers should take a life-cycle view of processes when undertaking efficiency studies. The authors rely heavily on a process-oriented methodology in their analysis of performance drivers in financial services. The study does not focus on traditional measures of productivity or financial performance. Rather, the authors base comparisons on intermediary measures which evaluate the drivers of performance from the perspective of all participants in the co-productive process. This pilot study starts with consumer financial services and in particular, retail banking. The authors review the relevant literature on financial services performance and then propose a conceptual framework for the study. The framework assumes that industry conditions and firm strategy are given. The authors focus is to examine the components of performance that managers can affect, given a strategy and industry operating conditions. Thus, their initial focus is guided by their desire to direct attention to issues of implementation and their effects on performance. The authors attempt to bridge the gap between traditional productivity measures and difficult-to-measure financial performance by developing a set of value creation components as an intermediary set of performance indicators. Based on pilot interviews, these indicators reflect effective performance in ways that are more meaningful than the more traditionalmeasure of productivity, as they are the goals toward which bank management strives. The key values the study attempts to measure are customer convenience, precision, efficient cost structure, adaptability and market penetration. The survey conducted by the research team benchmarks two types of management decisions that are presumed to drive these outcomes. The first set of management choices are implementation choices, human resources choices, technology implementation processes and product/servicedelivery processes. The second set of choices relates to management infrastructure, resource management processes, the information architecture of the firm, the performance management and control systems and the organizational structure of the firm. Based on interviews and the work of previous productivity studies, the research team developed a pilot survey focused on the practices of the functional areas, business lines, product groups and the retail distribution network. The pilot measured the outcomes and choices made by managers in seven large commercial banks. The pilot results will lead to a large scale survey of practices for the entire retail banking sector. Based on early pilot results, the researchers concluded that managers in consumer financial services firms typically assume that improvement in one area of performance is largely at the expense of decreased performance in other areas. The authors believe this is only partly true. Based on the pilot results, the authors believe that better management practices can move outcomes in a number of areas simultaneously. Through effective process design, use of technology and management of human resources, institutions can improve performance in multiple categories. The successful financial services organizations will be those which find processes and practices that enhance multiple measures of performance. The results of the large scale survey of practices will be available in early 1996.
Inside the Black Box: What Makes a Bank Efficient?
A decade of econometric research has shown that X-efficiency dominates scale and scope as the drivers of inefficiency in the U.S. banking industry. However, this research falls short in explaining the causes of the high degree of X-efficiency in the industry. This paper summarizes a four-year research effort to understand the drivers of this inefficiency. Key findings from this research, based on the most comprehensive studies to date of management practices in the retail banking industry, give insight into the drivers of X-efficiency. The paper provides a comprehensive framework for the analysis of X-efficiency in financial services. This paper was presented at the Wharton Financial Institutions Center's conference onRetail Banking, Services, Efficiency, Technology Management, Human Resource Management
Do Better Customers Utilize Electronic Distribution Channels? The Case of PC Banking
Many service firms are pursuing electronic distribution strategies to augment existing physical infrastructure for product and service delivery. But little systematic study has been made for whether and how characteristics or behaviors might differ between customers who use electronic delivery systems and those who use traditional channels. We explore these differences by comparing customers who utilize personal-computer-based home banking (PC banking) to other bank customers. Case studies and detailed customer data from four institutions suggest that PC banking customers are apparently more profitable, principally due to unobservable characteristics extant before the adoption of PC banking. Demographic characteristics and changes in customer behavior following adoption of PC banking account for only a small fraction of overall differences. It also appears that retention is marginally higher for customers of the online channel
Ultralight vector dark matter search using data from the KAGRA O3GK run
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM
