Question: How many customers do you need to interview in order to develop a high quality buyer persona?
- About 15
- One or two
- All of them
- Approximately 20% of your customer database
Explanation
Interviewing about 15 customers provides a sufficient sample to identify patterns in goals, challenges, and behaviors without being unmanageable. This number balances depth of insight with practical feasibility and allows for meaningful persona development. Insights from these interviews are combined with data to create accurate and actionable buyer personas. Sampling a representative group ensures relevance across the broader customer base.
Why the other options are incorrect
B) One or two interviews do not provide enough perspective to develop a reliable persona.
C) Interviewing all customers is unnecessary and impractical for persona creation.
D) Using 20% of the database is often excessive and may not yield additional useful insights beyond a smaller, representative sample.
