High-quality data and valid results depend primarily on the skills and the accuracy of the interviewers. Intensive training, qualification and monitoring of the interviews are thus the key factors on the way to gathering reliable data.
Each new interviewer at Trend Test first passes through a one-hour application meeting and a full-day training following the content: Fundamentals of market research, communication techniques, handling of the Quancept software. Prior to the first actual assignment, interviewers carry out test interviews. All interviewers are carefully coached in the first days and subsequently receive permanent personal support from our supervisors according to the guidelines from ISO 20252.
