What is the role of questionnaire in a customer survey?

Open ended and multiple questions.

Either type of question (open-ended,close-ended) can be used in a wide variety of scenarios. However, if you're looking for a guide to liken these types of questions to, you can think of close-ended questions as multiple choice questions on a school exam and open-ended questions as short responses and essay questions on an exam.

Open-ended Questions

Open-ended questions require a response with more depth and a lengthier response. Open-ended questions are also helpful in finding out more about a person or a situation, whether it's during an interview, at a party, or when getting to know a new friend.

Close-ended Questions

Close-ended questions can be answered in only one word or very short phrase. Close-ended questions can also be used in the situations mentioned above, although they have the potential to end the conversation.

Here are examples of close-ended questions in these types of situations:

• Would you like vanilla ice cream?
• Have you ever met Joe before?
• Where did you go to college?
• What is your best quality?
• Are you happy?
• Do you enjoy your car?
• Does your brother have the same interests as you?
• Do you have a pet?
• Do you like animals?
• When is your birthday?
• Do you like rain? 

Now, here's some examples of these close-ended questions turned into open-ended questions - to keep the conversation going:

• What is your favorite flavor of ice cream and why?
• How did you meet Joe?
• What do you feel was most beneficial about your college experience?
• How can your top qualities help our company to thrive and grow?
• What are some of the things that bring you the most joy?
• Why did you decide to purchase a Volvo?
• What interests do you and your brother share, and which interests do you not share?
• Do you have a pet and what is your pet like?
• Do you like animals and why?
• When is your birthday and how do you like to celebrate?
• Do you like rain and what do you usually do during rain storms?

Hi Sir

In most cases open ended and multiple choice questions would do. But when the answer  would affect the self respect of the customer , when an honest answer may not be forthcoming ( for example – If I am asked do I use branded products my answer would be yes but actually I may not be able to afford the brand and may go for an unbranded product. ) In these circumstances I think

• Word association • Sentence completion • Story completion • Picture • Thematic Apperception test would be more useful to get the correct information.
