Loft Industries sells roof trusses to contractors and builders and is currently looking for honest feedback on its services. However, in the past, most of its efforts to procure feedback from customers did not yield any meaningful data. According to the marketing managers of Loft Industries, feedback was more polite than honest. Which of the following contact methods should Loft Industries most likely use to maximize its chances of receiving honest and impersonal feedback?
A) online focus groups
B) telephone interviews
C) mail questionnaires
D) group interviews
E) personal interviews

Given that the company needs honest and sincere feedback regarding the quality of its products, and that its clients have so far not given the desired answers due to their education and lack of critical focus as a way to avoid hypothetical conflicts, the correct way to obtain honest and impersonal feedback regarding the quality of their products would be through mail questionnaires.

This is so because through these questionnaires, direct contact between the members of the company and its clients would be avoided, making the criticism or assessment much less personal for the client, which could be expanded without fear of possible reproach on the part of the members of Loft Industries. In this way, a space of sincere expression would be generated that would allow an objective assessment on the part of the clients.
