How to Turn a 5-Minute Customer Call Into a Publish-Ready Case Study
How to Turn a 5-Minute Customer Call Into a Publish-Ready Case Study
A practical walkthrough of the 5-question voice interview structure that turns a brief customer conversation into a complete, publish-ready case study.
The Old Way vs the New Way
Traditional: identify customer, email, wait 2 weeks, schedule 45-minute Zoom (rescheduled twice), conduct interview, send to writer, wait for draft, review, get customer approval, wait again. 6-8 weeks.
New: send customer a link, they answer 5 questions by voice on their own time (5 minutes), AI generates a structured draft, you edit and publish. 1-3 days.
Preparing Your Questions
Before sending the interview:
- ●Review the customer's account data. Know their company, industry, and which features they use.
- ●Prime the customer. "This will take about 5 minutes and we'll ask about results you've seen."
The 5-Question Voice Interview Structure
Question 1: "Tell us about your company and your role. What was your situation before using [product]?" → Maps to Company Background + Situation
Question 2: "What specific problem made you start looking for a solution?" → Maps to Challenge (the trigger event and pain)
Question 3: "Why did you choose [product] over other options?" → Maps to competitive differentiation
Question 4: "What specific results have you seen? Can you share numbers?" → Maps to Results (the most important question)
Question 5: "Would you recommend [product]? What would you tell someone in a similar role?" → Maps to closing quote
What AI Extracts
A well-built system extracts:
- ●Key metrics and numbers
- ●Direct quotes (cleaned of filler words)
- ●Narrative structure mapped to case study format
- ●Company details from context
- ●Emotional language that captures authentic voice
Editing and Polishing (15-30 minutes)
- ●Verify metrics. Quick email: "You mentioned 35% increase — can we use that number?"
- ●Tighten quotes. Clean up while preserving their actual voice.
- ●Add context. Fill in product feature names and industry terminology.
- ●Write the headline. Use the primary metric.
