The advantage of self-administered questionnaire in this case is that it is cheap and easy to administer, fast, preserve confidentiality, is anonymous and can be completed at respondent’s convenience and can be administered in a standard manner. Questionnaires are best used in collecting factual data and in this case those are employees preferences.
