The face to face inquiry: Except in the case of requirement of the research or in case of a request by a customer, the face to face questionnaire is the most frequently used technique.
The inquiry opposite in face is generally realized by the visit of the interviewer at home to optimize the conditions of signing of the questionnaire, by avoiding influences and the drawbacks of questionnaires led in the street or in the professional place.
Interviews are also led in rooms in neutral premises, in the case of testing products (notably food requiring very definite conditions of conservation), or for quantitative tests of commercials.
The phone inquiry: Our team of quantitative studies is more and more sought to lead phone inquiries, notably for studies of satisfaction, on the basis of listings supplied by the customer. This method provides a better mastery of the operation and an unmistakable saving of time, especially when it is a question of covering remote geographic zones, or of getting in touch with very definite professional sectors.
The mail inquiry: This inquiry bases also itself on referees' addresses listings. It is rarely used by El Amouri Institute due to the weak rate of return, and the way of an auto-administered questionnaire. This method is adopted on inquiry and in case of simple questionnaires and of relatively flexible delays. Quantitative observations: A lot of useful information for marketing can be obtained by observing only people or phenomena rather than by proceeding by interviews. To be reliable and to reach the objectives, this technique requires a good training of the investigators called to give evidence of an excellent mastery of the object of the study and its end. The degree of structuralization of the observation and of the used tool is dependent on the degree of understanding of the studied phenomenon. The study generally bases itself on a railing elaborated in a special way to minimize the risks of subjectivity.
