TL;DR: Findings indicate that SERVQUAL suffers from a number of conceptual and empirical difficulties and that some alternative to difference scores is preferable and should be utilized and caution should be exercised in the interpretation of IS-SERVQUAL difference scores.
Abstract: A recent MIS Quarterly article rightfully points out that service is an important part of the role of the information systems (IS) department and that most IS assessment measures have a product orientation (Pitt, et al. 1995). The article went on to suggest the use of an IS-context-modified version of the SERVQUAL instrument to assess the quality of the services supplied by an information services provider (Parasuraman, et al. 1985, 1988, 1991). However, a number of problems with the SERVQUAL instrument have been discussed in the literature (e.g., Babakus and Boller 1992; Carman 1990; Cronin and Taylor 1992, 1994; Teas 1993). This article reviews that literature and discusses some of the implications for measuring service quality in the information systems context. Findings indicate that SERVQUAL suffers from a number of conceptual and empirical difficulties. Conceptual difficulties include the operationalization of perceived service quality as a difference or gap score, the ambiguity of the expectations construct, and the unsuitability of using a single measure of service quality across different industries. Empirical problems, which may be linked to the use of difference scores, include reduced reliability, poor convergent validity, and poor predictive validity. This suggests that (1) some alternative to difference scores is preferable and should be utilized; (2) if used, caution should be exercised in the interpretation of IS-SERVQUAL difference scores; and (3) further work is needed in the development of measures for assessing the quality of IS services.

TL;DR: In this paper, the authors examined the need for IS assessment and suggested a comprehensive IS assessment framework linked to organizational performance using existing IS assessment theory as a base and incorporating measurement concepts from other disciplines.
Abstract: Information Systems IS managers are under increasing pressure to justify the value and contribution of IS expenditures to the productivity, quality, and competitiveness of the organization. This paper examines the need for IS assessment and suggests a comprehensive IS assessment framework linked to organizational performance using existing IS assessment theory as a base and incorporating measurement concepts from other disciplines. The existing models of IS success are updated to include the emerging IS success dimensions of service quality and work group impact and provide a comprehensive method for organizing the various measures of IS success. In addition, many new measures from recent research are presented to supplement the lists supplied by previous research. Additional research is suggested to advance the IS assessment contingency theory. Such a theory has the potential to contribute to the quality and productivity of the IS function and the larger organization by providing feedback to manage and improve the IS function to better meet the needs of the organization.

TL;DR: Surprisingly, the results of the current analysis showed no significant link between IT capability and firm performance with data from the 2000s.
Abstract: Several studies support the positive link between information technology capability and firm performance, including Bharadwaj (2000) and Santhanam and Hartono (2003), which appeared in MIS Quarterly. We conducted a study to see if this link is still statistically significant. It is now over a decade since the first study was published, during which several significant developments in the IT industry have taken place. Unlike the 1990s, when proprietary information systems prevailed, the 2000s are characterized by more standardized and homogeneous information systems and with the rapid adoption of ERP and web technologies. Thus, we attempted to reexamine the link between IT capability and firm performance with data from the 2000s. Surprisingly, the results of our current analysis showed no significant link between IT capability and firm performance. Contrary to earlier studies, IT leader firms in our study didn't show better financial performance than control firms. We discuss several possible causes for the change in findings and present an in-depth comparison in business performance between the two groups--IT leader and control--over a period extending from 1991 to 2007.

TL;DR: It is found that service convenience, Web site service quality, and risk are significant factors affecting consumers' satisfaction level, which in turn affects intention, suggesting that managers need to understand e-convenience from the consumers' perspective.
Abstract: E-service is an emerging and rapidly evolving area as demonstrated by new technological innovations introduced to improve e-service. Motivated by the growing interest in online commerce, we focus our research questions on examining the factors that contribute to e-service, the relationships among these factors and the consumers' attitude toward e-service. To explore answers to our research questions, we developed an e-service model. Specifically, our proposed model consists of such constructs as individual differences, e-service convenience, Web site service quality, risk, e-satisfaction, and intention. We develop an e-service quality survey instrument and use empirical data to validate the instrument. The results of our empirical study validate our eight hypotheses. We confirm seven of the eight hypotheses. One hypothesis that tested individual differences and service convenience was not confirmed. However, we found that service convenience, Web site service quality, and risk are significant factors affecting consumers' satisfaction level, which in turn affects intention. The findings suggest that managers need to understand e-convenience from the consumers' perspective. In order to provide better services for users, companies need to invest in Web site service quality design and evaluation, and at the same time, control the perceived risk associated with using it.

TL;DR: This book by a teacher of statistics (as well as a consultant for "experimenters") is a comprehensive study of the philosophical background for the statistical design of experiment.
Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

TL;DR: This paper discusses many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to the original model.
Abstract: Ten years ago, we presented the DeLone and McLean Information Systems (IS) Success Model as a framework and model for measuring the complex-dependent variable in IS research. In this paper, we discuss many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to our original model. Based on our evaluation of those contributions, we propose minor refinements to the model and propose an updated DeLone and McLean IS Success Model. We discuss the utility of the updated model for measuring e-commerce system success. Finally, we make a series of recommendations regarding current and future measurement of IS success.

TL;DR: Deming's theory of management based on the 14 Points for Management is described in Out of the Crisis, originally published in 1982 as mentioned in this paper, where he explains the principles of management transformation and how to apply them.
Abstract: According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.
