Open-Ended Questions
– Open-ended interview questions allow interviewees to respond how they wish, and to what length they wish

detail– May take too much time – May lose control of the interview

Chapter 5: Interviewing
Closed Interview Questions
• Closed interview questions limit the number of possible responses
• Closed interview questions are appropriate for generating precise, reliable data which is easy to analyze
• The methodology is efficient, and it requires little skill for interviewers to administer

Closed Interview Question Example
• On average, how many call does the call centre receive monthly?
• List your top 2 priorities for improving the technology infrastructure.
• Which of the following source of info is most valuable to you:– Completed customer complaint form– Email complaint from customers who visit the

Chapter 5: Interviewing
Probing Questions
• Probing questions elicit more detail about previous questions
• The purpose of probing questions is to get more meaning, clarify or explain interviewee’s point

Chapter 5: Interviewing
Probing Question Example
• Why?• Can you give an example?• Will you elaborate on that for me?• What makes you feel that way?

Chapter 5: Interviewing
Question Pitfalls
• Avoid leading questions that imply an answer– “You agree with other managers that inventory
control should be computerized, don’t you?”
• Avoid asking two questions at once– What decisions are made during a typical day and
how do you make them?
• These questions should be avoided because interviewees may answer only one question,

Chapter 5: Interviewing
Question Sequencing
• There are three basic ways of structuring interviews:– Pyramid Structure
• starting with closed questions and working toward open-ended questions
– Funnel Structure• starting with open-ended questions and
working toward closed questions
– Diamond Structure• starting with closed, moving toward open-
ended, and ending with closed questions

Chapter 5: Interviewing
Pyramid Structure
• Begins with close-ended questions• Expands by allowing open-ended
questions and more generalized responses
• Is useful if interviewees need to be warmed up to the topic or seem reluctant to address the topic

Chapter 5: Interviewing
Pyramid Structure Interview Example

Chapter 5: Interviewing
Funnel Structure
• Begins with generalized, open-ended questions
• Concludes by narrowing the possible responses using closed questions
• Provides an easy, non-threatening way to begin an interview
• Is useful when the interviewee feels emotionally about the topic

Chapter 5: Interviewing
Funnel Structure Interview Example

Chapter 5: Interviewing
Diamond Structure
• A diamond-shaped structure begins in a very specific way
• Then more general issues are examined

interviewee's interest and attention through a variety of questions
