Loyalty business model

A model by Kaj Storbacka, Tore Strandvik, and Christian Grönroos (1994), the service quality model, is more detailed than the basic loyalty business model but arrives at the same conclusion.^[1] In it, customer satisfaction is first based on a recent experience of the product or service. This assessment depends on prior expectations of overall quality compared to the actual performance received. If the recent experience exceeds prior expectations, customer satisfaction is likely to be high. Customer satisfaction can also be high even with mediocre performance quality if the customer's expectations are low, or if the performance provides value (that is, it is priced low to reflect the mediocre quality). Likewise, a customer can be dissatisfied with the service encounter and still perceive the overall quality to be good. This occurs when a quality service is priced very high and the transaction provides little value.


This loyalty business model then looks at the strength of the business relationship; it proposes that this strength is determined by the level of satisfaction with recent experience, overall perceptions of quality, customer commitment to the relationship, and bonds between the parties. Customers are said to have a "zone of tolerance" corresponding to a range of service quality between "barely adequate" and "exceptional". A single disappointing experience may not significantly reduce the strength of the business relationship if the customer's overall perception of quality remains high, if switching costs are high, if there are few satisfactory alternatives, if they are committed to the relationship, and if there are bonds keeping them in the relationship. The existence of these bonds acts as an exit barrier. There are several types of bonds, including: legal bonds (contracts), technological bonds (shared technology), economic bonds (dependence), knowledge bonds, social bonds, cultural or ethnic bonds, ideological bonds, psychological bonds, geographical bonds, time bonds, and planning bonds.


This model then examines the link between relationship strength and customer loyalty. Customer loyalty is determined by three factors: relationship strength, perceived alternatives and critical episodes. The relationship can terminate if:


The final link in the model is the effect of customer loyalty on profitability. The fundamental assumption of all the loyalty models is that keeping existing customers is less expensive than acquiring new ones. It is claimed by Reichheld and Sasser (1990) that a 5% improvement in customer retention can cause an increase in profitability between 25% and 85% (in terms of net present value) depending upon the industry. However, Carrol and Reichheld (1992) dispute these calculations, claiming that they result from faulty cross-sectional analysis.^[2]


According to Buchanan and Gilles (1990),^[3] the increased profitability associated with customer retention efforts occurs because:


For this final link to hold, the relationship must be profitable. Striving to maintain the loyalty of unprofitable customers is not a viable business model. That is why it is important for marketers to assess the profitability of each of its clients (or types of clients), and terminate those relationships that are not profitable. In order to do this, each customer's "relationship costs" are compared to their "relationship revenue". A useful calculation for this is the patronage concentration ratio. This calculation is hindered by the difficulty in allocating costs to individual relationships and the ambiguity regarding relationship cost drivers.

Satisfaction-profit-chain (SPC) model[edit]

The satisfaction-profit chain is a model that theoretically develops linkages and then enables researchers to test them statistically for a firm using customer data (both from surveys and other sources). The satisfaction-profit-chain was tested in the context of banking industry showing that product and services improvements indeed were associated with customer perceptions, which led to beneficial customer behaviors such as repurchase, and desirable financial outcomes such as increased sales and profitability ^[4] The satisfaction-profit-chain, as a methodology for managing customer loyalty and firm profitability, is also applicable in business-to-business markets, irrespective of whether the B2B firm sells goods and/or services.


The satisfaction-profit-chain refers to a chain of effects whereby increased performance on key attributes leads to improvements in overall satisfaction, which in turn affects loyalty intentions and behaviors. The increased customer loyalty is shown to affect short- and long-term financial outcomes including sales, profitability, and stock price. More recently, some studies show that especially in the context of services such as retailing and financial services, employee satisfaction can play a critical role in enhancing customer loyalty. This happens because both customer satisfaction and employee satisfaction can mutually reinforce each other, and promote stronger customer loyalty. More specifically, for a given level of overall satisfaction, customer loyalty is disproportionately stronger when customers perceive that employees are also satisfied.


The SPC model has become the basis of a large body of empirical research showing the strong impact of customer satisfaction on customer loyalty. Research has clearly shown that one of the best ways to increase customer loyalty—measured as repurchase intentions and/or repurchase behavior—is by increasing customer satisfaction (more satisfied customers are more loyal, in general).^[5][6][7] Though the relationship is positive, research shows there are many differences:


1) The effect of customer satisfaction on customer loyalty can vary based on customer demographics and segments, such that it is stronger for some demographic groups and segments than others.^[6][8]


2) The effect of customer satisfaction and customer loyalty, and subsequent financial outcomes for firms, can vary based on industry. Specifically, factors such as—goods versus services industry, degree of competition or concentration in the industry, the utilitarian or hedonic nature of products, and customers' switching costs can affect the nature (non-linearity) and strength of the link between customer satisfaction and customer loyalty.^{[9][10][11][7]}


3) The measurement of loyalty—especially for customers is multi-faceted. Customer loyalty includes a variety of outcomes—intentions and behaviors associated with repurchase including word-of-mouth,^[12][13] complaint behaviors,^[14] share-of-wallet or the relative proportion of purchasing from a single firm relative to customer's total purchasing,^[15] and likelihood to recommend.^[16]


4) Customer loyalty is influenced, not only by customer satisfaction but also employee satisfaction. Customer loyalty is a function of customer satisfaction. In many firms, especially service-oriented industries such as retailing, health-care, financial services, education, and hospitality the level of satisfaction experienced by front-line employees is a critical component. The level of employee satisfaction influences customer satisfaction as shown in a large-scale study of managers, front-line employees, and customers of a DIY retailer in Europe:^[17] results showed that managers affected overall job-satisfaction of front-line employees, which in turn affected the satisfaction of customers they interacted with. Most surprisingly, the level of customer loyalty was much higher among those customers who were themselves more satisfied, but also interacted with more satisfied employees. Highly satisfied customers who dealt with relatively less satisfied employees were relatively less loyal.
