Quizplus · Accepted Answer

A questionnaire allows for the efficient collection of information from many different people in a standardized way. It also enables anonymity for respondents, which may increase response rates and honesty in their answers. Interviews can be time-consuming and may not be practical to conduct with a large number of people. Observation by the analyst may not capture all relevant information, and system documentation may not involve input from individual users.
