How to create target personas that actually drive decisions
A practical guide to building user personas based on real research data, not assumptions. Learn what makes a persona useful versus decorative.
By Idea Research team
Every product team has personas. Few product teams actually use them.
The problem isn't personas themselves—it's how they're created. Too many personas are based on assumptions rather than research, filled with irrelevant details, and filed away never to be seen again.
This guide will help you create target personas that actually inform product decisions.
What makes a useful persona?
A good persona is a tool for decision-making. When you're debating a feature, you should be able to ask "What would [Persona] think about this?" and get a useful answer.
This requires personas that are:
- Based on research: Real data about real users, not assumptions
- Specific enough to be useful: "Busy professional" isn't specific enough
- Focused on relevant details: Their favourite coffee doesn't matter unless you're building a coffee app
- Distinct from each other: If two personas would make the same decisions, you only need one
How to research your personas
Start with what you know
Before conducting new research, gather existing data:
- Customer support tickets and common questions
- Sales call notes and objections
- Analytics data on user behaviour
- Reviews and feedback from current users
Conduct user interviews
Talk to 5-10 people from each potential segment. Focus on:
- Their goals and what they're trying to achieve
- Their current process and pain points
- How they evaluate and choose solutions
- What constraints they face (time, budget, skills)
Look for patterns
As you analyse your research, look for clusters of users who share similar goals, behaviours, and constraints. These clusters become your personas.
What to include in a persona
Keep personas focused on information that affects product decisions:
- Role and context: What do they do? What's their environment?
- Goals: What are they trying to achieve?
- Pain points: What frustrates them about current solutions?
- Decision criteria: How do they evaluate options?
- Constraints: What limits their choices?
Skip the stock photo and fictional name unless they genuinely help your team remember the persona. Focus on the details that matter.
Keeping personas alive
Personas are only useful if people actually use them. Some ways to keep them relevant:
- Reference them in product discussions and planning sessions
- Update them as you learn more about your users
- Use them to evaluate new feature ideas
- Share quotes and insights from real users who match each persona
Using AI to explore personas
AI-powered tools can help you explore how different personas might respond to your product. By creating synthetic users based on your persona research, you can:
- Test messaging and positioning with different segments
- Identify questions and objections each persona might have
- Explore edge cases and scenarios you hadn't considered
- Validate assumptions before talking to real users
This doesn't replace research with real users, but it helps you move faster and think more deeply about different perspectives.
