1.1.3. Some models of customer satisfaction research and quality measurement
Service volume:
1.1.3.1. American Customer Satisfaction Index (ACSI):
In the American satisfaction index (ACSI) model, perceived value is influenced by perceived quality and customer expectations. Then, customer expectations have a direct impact on perceived quality.
Customer satisfaction index consists of factors (variables), each factor is made up of many specific elements characteristic of the product or service.
Customer satisfaction is defined as a comprehensive assessment of the use of a service or after-sales activity of a business and this is the core point of the CSI model (customer satisfaction index model).
Surrounding this variable is a system of causal relationships originating from initial variables such as:
Customer expectations, corporate and product image, perceived quality and perceived value of the product or service are related to outcome variables of satisfaction such as customer loyalty or customer complaints.

Figure 4: US customer satisfaction index model
(American Customer Satisfaction Index – ACSI)
1.1.3.2. European Customer Satisfaction Index (ECSI) model:
The EU Country Satisfaction Index (ECSI) model has certain differences. Compared to ACSI, product and brand image has a direct impact on customer expectations. In this case, customer satisfaction is the combined impact of four factors: image, perceived value, and perceived quality of both tangible and intangible products. Normally, the ACSI index is often applied to the public sector, while the ECSI index is often applied to measure products and industries.

Figure 5: Customer satisfaction index model of EU countries
(European Customer Satisfaction Index – ECSI)
The strength of this approach is that it immediately shifts the consumer experience, facilitating the study of the causal relationship between factors that create customer satisfaction and loyalty. Therefore, the first goal of the CSI approach is to explain customer loyalty to a business, a country in general or a product in particular through the customer satisfaction index when directly or indirectly affected by the image, expectations, perceived quality and perceived value of that product and service.
