We can see them in many public places, such as service desks in hotels, service desks in shopping malls and business halls, tables and cards in restaurants, and pages in magazines. Generally, customers are required to choose 1-5 in terms of hygiene, quality, price, service speed and attitude. The content of comment cards is relatively short, and most of them can be viewed by customers. The suggestion box is a way for customers to record according to their own feelings. As a suggestion box, we often find that it has become a space for consumers to vent their dissatisfaction. We should find the cause of the problem from the customer's complaints in order to find a solution.

Second, the website survey

Internet is a good tool to measure customer satisfaction. With the continuous progress of technology, it is very convenient to establish a website, which can understand customers' expectations of products or services through customer feedback and enhance the insight of enterprises on product improvement. Many companies mark related websites on invoices and brochures, and encourage customers to participate in customer satisfaction surveys online. Frequently asked questions when using the website for investigation generally include the professional level of staff, service waiting time, cleanliness and price of facilities. The website will encourage customers to provide suggestions to improve their services or products. Network survey is not only low-cost, but also makes customers more free in time selection and easier to think. Now many enterprises have established their own official websites on FACEBOOK and Weibo, hoping to communicate with customers better, which is also a good way to promote themselves.

Third, telephone survey.

Many enterprises conduct telephone surveys through call centers. Considering the patience of customers, the questionnaire design is valid within 15 minutes. Although telephone survey is more expensive than the first two, it increases the emotional communication of many customers and makes it easier for customers to get formal pleasure. Especially after receiving services or buying products, the survey not only leaves a deep impression on customers, makes them feel valued, but also solves some problems in time. Some enterprises conduct telephone surveys through a third party, so it is necessary to train the interviewer's business knowledge or have a good process to help customers ask questions in time during the telephone survey.

Fourth, customer interviews.

Interviews will take up a lot of customers' time, and due to the limitation of time and place, such interviews are the most difficult and costly. But what is certain is that some customers are willing to communicate and provide suggestions for improvement. Listen to customers' views and feelings on brand, quality, service and business process through interviews, and also discuss customers' needs and expectations reflected by the first three research methods. To realize enterprise value, we should proceed from customer demand, realize customer satisfaction and pursue customer loyalty.
