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. 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.
