The quality of insights you gain from user interviews largely depends on the questions you ask. Crafting and asking effective questions is a skill that can significantly enhance the value of your user interviews.
Open-ended questions are invaluable in user interviews. They elicit detailed, thoughtful responses and allow participants to express themselves freely. Rather than asking, "Do you like our product?" try, "Can you tell me about your experience using our product?" This approach gives participants the opportunity to discuss various aspects of their experience—both positive and negative.
Be careful to avoid leading questions that might influence the participant's response. A question like "Don't you think our new feature is great?" suggests a desired answer. Instead, ask "What are your thoughts on our new feature?" This neutral phrasing allows the participant to share their honest opinion.
Focus on actual behaviors rather than hypotheticals. People are often poor predictors of their own future behavior, so asking "Would you use this feature?" might not yield accurate insights. Instead, ask about past behaviors: "Can you tell me about the last time you encountered this problem?" This grounds the discussion in real experiences rather than speculation.
The "5 Whys" technique can be particularly effective in getting to the root of an issue. By asking "why" up to five times in response to each answer, you can uncover deeper motivations and underlying causes of behaviors or opinions. For example:
- "Why did you choose our product?"
- "Why was ease of use important to you?"
- "Why were you looking to save time?"
- "Why were you taking on additional projects?"
- "Why was career advancement a priority for you at that time?"
This line of questioning might reveal that a user chose your product not just because it was easy to use, but because they were ultimately looking for career advancement opportunities.
Storytelling prompts can elicit rich, contextual information. Ask participants to describe specific experiences in detail. For instance, "Could you walk me through your most recent online product purchase?" This narrative approach often uncovers details that might not surface in response to more direct questions.
Contrast questions can be useful in understanding preferences and trade-offs. Asking "How does this process compare to how you did it before?" can highlight the relative strengths and weaknesses of different approaches or products.
Finally, don't underestimate the power of silence. After a participant answers, wait a few seconds before asking the next question. Often, they'll fill the silence with additional, valuable information. This technique can lead to some of the most insightful comments in an interview.
