Mystery Shopping
Mystery shopping is a form of measuring the quality of service or its compliance to regulations. In this survey, the researcher takes on the role of a given person (usually the client). Playing the activities (e.g. willingness to buy goods or lodging a complaint) planned before and playing specific roles (e.g. an aggressive client), the mystery shopper observes the behavior of the surveyed person unconscious of the fact that she or he participates in a survey. The training function of mystery shopping is to use it as a mechanism of initial analysis allowing to recognize the typical behavior of people included in the development process.
