A. Pre-test the questionnaire
1. Show it to colleagues and key decision-makers. Are the questions and responses valid and reliable? Are they appropriate? Are they both necessary and sufficient?
2. Administer the questionnaire to a small number of people who resemble or are drawn from the population of interest, but it does not have to be a random sample. Measure how much time it takes to complete each questionnaire. Debrief the respondents (and the interviewers if applicable) after they complete the questionnaire. Analyze the information provided to clarify directions, question wording, or response categories where necessary. Revise as needed.
B. Pilot Study
A pilot study is a dress referral of the full project, including the questionnaire, the interviewers, and all other aspects. Often a sample of 30-50 responses are obtained, coded, and analyzed. Questions that are not providing useful data are discarded, and the final revisions of the questionnaire are made.
