Customer satisfaction has become one of the main objectives in all areas of business, especially the tourist trade. One of the most difficult problems is to know how to obtain this satisfaction, which involves identifying customers' needs and desires, and transferring them to our product or service specifications. In order to ascertain the consumer voice, we can ask consumers directly, or thy to deduce their requirements by indirect methods. Statistical design of experiments (SDE) is considered to be a powerful tool for evaluating the revealed importance that not only shows the weight of the most relevant aspects but also that of their interactions. The aim of this paper is to show SDE's application in designing a tourist route. It also makes suggestions and offers directions for future applications, focusing in particular on marketing services.
