Businesses have always had a rough time attempting to understand exactly what their customers think about their product, especially criticism. Of course, ultimately a company will see the results in the form of reduced sales, but by the time this happens, it is usually too late to do anything. No mid-course correction can be made. A business has already lost a great deal of money.

A customer satisfaction survey is a metric that helps companies and/or employees gauge the satisfaction level of their customers. In short, it is a questionnaire that is sent out to customers asking them about their experience. Depending on how the survey is designed, customers can convey their opinions by providing ratings, answering multiple choice questions, by filling out text boxes, or even by giving vocal feedback.
