Determine the goals of creating questionnaires: First and foremost, determine the objective of creating a questionnaire: Is it for market research purpose? Do you intend to collect customer feedback? Or is it a part of routine employee engagement surveys? Hence, deciding the objective keeps you focused and narrows down your efforts while creating questions.
Brainstorming the right questions: Herein, you need to decide the type of questions, questionnaire length, etc. Make sure that you have a balanced mix of both open-ended and closed-ended questions in your questionnaire. This keeps the audience engaged throughout the exercise. Similarly, make the questionnaire length short with just 8-10 questions to avoid audience fatigue.
