Conducting Effective User Interviews

Talking to customers sounds easy, but doing it in a way that yields unbiased, actionable insights is a science. People naturally want to please you, and if you ask them about the future, they will lie (unintentionally). To get the truth, you must focus on the past and present.

The Golden Rule: Don't Ask About the Future

If you ask a user: "Would you buy a tool that automatically generates reports?", they will say: "Yes, definitely!". It costs them nothing to say yes. However, when you launch it and charge $20/month, they disappear.

Instead, ask about their past behavior: "Tell me about the last time you had to create a report. Walk me through exactly what you did, step-by-step."

Avoid Leading Questions

A leading question guides the user toward a specific answer. Look at these contrasts:

Leading (Bad)	Neutral (Good)
"Do you find our current checkout page frustrating?"	"Walk me through your experience during your last checkout."
"Would you use a feature that does X?"	"How do you currently handle X? What challenges do you face?"

The Five Whys Technique

To get to the root cause of a user's behavior, use the "Five Whys" technique developed by Sakichi Toyoda. Keep drilling down until you reach the underlying emotional or structural reason for their action:

1. "Why did you export the spreadsheet manually?" Because the report was missing data.
2. "Why was it missing data?" Because the database doesn't sync in real time.
3. "Why does it need to sync in real time?" Because I have to show live metrics to my VP at 9 AM.
4. "Why do you need live metrics?" Because he makes daily spending changes based on them.
5. "Why does he make daily changes?" Because our ad campaigns fluctuate rapidly and we lose money if we don't adjust them. (Ah! The real problem is financial loss due to slow ad budget adjustment, not just a spreadsheet export!)
