of high fineness, or at one of the relatively low.
When is rigorously carried out, sales analysis
allows the exact knowledge of the volume of
products sold, the tourist turnover recorded on
each product and each unit of sales and for
specified time periods, as well as estimating the
effectiveness of each operation in hand. Such an

meaning that not every travel agency has a system
of evidence sufficiently precise and capable of

b) Analysis of the information collected during the
taste of consumers, which presents the advantage
of obtaining timely and relevant data. The use of
such methods is affected but usually costs quite

those who make up the Panel and manage. It
