TL;DR: In this article, a mathematical framework for assessing the value of customer satisfaction is proposed, which enables managers to determine which customer satisfaction elements have the greatest impact, and how much money should be spent to improve particular satisfaction elements.

TL;DR: In this article, the authors present the "return on quality" approach, which is based on the assumptions that quality is an investment, quality efforts must be financially accountable, it is possible to spend too much on quality, and not all quality expenditures are equally valid.
Abstract: Many companies have been disappointed by a lack of results from their quality efforts. The financial benefits of quality, which had been assumed as a matter of faith in the “religion of quality,” are now being seriously questioned by cost-cutting executives, who cite the highly publicized financial failures of some companies prominent in the quality movement. In this increasingly results-oriented environment, managers must now justify their quality improvement efforts financially. The authors present the “return on quality” approach, which is based on the assumptions that (1) quality is an investment, (2) quality efforts must be financially accountable, (3) it is possible to spend too much on quality, and (4) not all quality expenditures are equally valid. The authors then provide a managerial framework that can be used to guide quality improvement efforts. This framework has several attractive features, including ensured managerial relevance and financial accountability.

TL;DR: It is shown that some of the most common beliefs about customer-perceived quality are wrong, and a useful simplification of reality is provided that successfully predicts many aspects of the dynamics of consumer response to quality.
Abstract: We show that some of the most common beliefs about customer-perceived quality are wrong For example, 1) it isnot necessary to exceed customer expectations to increase preference, 2) receiving an expected level of bad service does not reduce preference, 3) rational customers may rationally choose an option with lower expected quality, even if all nonquality attributes are equal, and 4) paying more attention to loyal, experienced customers can sometimes be counter-productive These surprising findings make sense in retrospect, once customer expectations are viewed as distributions, rather than simple point expectations That is, each customer has a probability density function that describes the relative likelihood that a particular quality outcome will be experienced Customers form these expectation distributions based on their cumulative experience with the good or service A customer's cumulative expectation distribution maybe conceptualized as being a predictive density for the next transaction When combined with a diminishing returns (ie, concave) utility function, this Bayesian theoretical framework results in predictions of: (a) how consumers will behave over time, and (b) how their perceptions and evaluations will change In managerial terms, we conclude that customers consider not only expected quality, but also risk This may help explain why current measures of customer satisfaction (which is highly related to expected quality) only partially predict future behavior We find that most of the predictions of our theoretical model are borne out by empirical evidence from two experiments Thus, we conclude that our approach provides a useful simplification of reality that successfully predicts many aspects of the dynamics of consumer response to quality These findings are relevant to both academics and managers Academics in the area of customer satisfaction and service quality need to be aware that it may be insufficient to measure only the point expectation, as has always been the standard practice Instead it may be necessary to measure the uncertainty that the customer has with respect to the level of service that will be received Due to questionnaire length constraints, it may not be practical for managers to include uncertainty questions on customer satisfaction surveys Nevertheless it is possible to build a proxy for uncertainty by measuring the extent of experience with the service/good, and this proxy can be used to partially control for uncertainty effects The findings of the study were obtained using 1) an analytical model of customer expectation updating, based on aset of assumptions that are well-supported in the academic literature, and 2) two behavioral experiments using human subjects: a cross-sectional experiment, and a longitudinal experiment Both the analytical model and the behavioral experiments were designed to investigate the effects that distributions of expectations might have, and especially the effects that might deviate from the predictions that would arise from a traditional point expectation model The behavioral experiments largely confirmed the predictions of the analytical model As it turned out, the analytical model correctly (in most cases) predicted behavioral effects that contradict some of the best-accepted "truisms" of customer satisfaction It is now clear that a more sophisticated view of customer expectations is required-one that considers not only the point expectation but also the likelihood across the entire distribution of possible outcomes This distinction is not "just academic," because it results in predictable behavior that deviates significantly from that which was traditionally expected based on simpler models

TL;DR: In this article, a collection of customer satisfaction measures around the managerial processes themselves is organized, which forms a natural bridge from the customer to management and allows management to track the impact of quality improvements all the way from internal process measures to overall customer satisfaction and market share.
Abstract: Too often, quality programs fail to improve quality because they concentrate on internal processes which do not affect the customer. This is at least partially due to the alienation of marketing from the quality movement, a situation for which both sides are partially at fault. Ideally, marketing should serve as the eyes and ears of the organization, linking the external customer to managerial processes. One way to do this is to organize the collection of customer satisfaction measures around the managerial processes themselves. This forms a natural bridge from the customer to management and allows management to track the impact of quality improvements all the way from internal process measures to overall customer satisfaction and market share.

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.
