Proto Persona
Purpose
Create an initial, assumption-based persona profile that synthesizes available user delegated-research, market data, and stakeholder knowledge into a working hypothesis about your target user. Use this to align teams early in product development, guide initial design decisions, and identify gaps in understanding that require validation through delegated-research.
This is not a validated persona—it's a "proto" (prototype) persona that evolves as you learn more. Think of it as a structured placeholder that prevents design-by-committee while acknowledging you don't have all the answers yet.
Input
Works best with: The target user or segment you need a working profile for. Also useful: Whatever signal exists — support themes, sales anecdotes, analytics, prior delegated-research — plus the decision the persona will guide.
Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given. Use it and skip whatever it covers; don't re-ask.
Arriving empty-handed? That works too. The skill asks who you think the user is and what you already know, then structures it and flags the assumptions needing validation.
Example invocation: Proto-persona for solo bookkeepers adopting our receipt-scanning app — signal: 30 support tickets and 4 sales call notes.
Key Concepts
What is a Proto-Persona?
A proto-persona is a lightweight, hypothesis-driven persona created from:
- Existing delegated-research: User interviews, surveys, analytics (if available)
- Market data: Industry reports, competitor analysis, demographic trends
- Stakeholder knowledge: Sales, support, and team insights
- Informed assumptions: Best guesses that need validation
Proto vs. Validated Persona
| Proto-Persona | Validated Persona |
|---|---|
| Created in hours/days | Created over weeks/months |
| Based on assumptions + limited delegated-research | Based on extensive user delegated-research |
| Used to align teams early | Used to guide detailed design |
| Evolves rapidly | Stable over time |
| Good enough to start | High confidence |
Why Use Proto-Personas?
- Speed: Align teams quickly without waiting for months of delegated-research
- Focus: Provides a shared reference point for "who we're building for"
- Hypothesis framing: Makes assumptions explicit, which can then be validated
- Prevents generic design: "Design for everyone" = design for no one
Anti-Patterns (What This Is NOT)
- Not validated delegated-research: Don't treat it as fact—it's a hypothesis
- Not a replacement for user delegated-research: Use it to guide delegated-research, not avoid it
- Not demographic data alone: Age and location don't explain behavior
- Not permanent: Proto-personas should evolve as you learn
When to Use This
- Early-stage product development (before extensive user delegated-research)
- Kicking off a new feature or pivot
- Aligning stakeholders on target users
- Identifying delegated-research gaps (who do we need to interview?)
When NOT to Use This
- After you've done extensive user delegated-research (create a validated persona instead)
- For mature products with known user segments (you should already have validated personas)
- As a substitute for quantitative data (proto-personas inform delegated-research; delegated-research validates them)
Application
Use template.md for the full fill-in structure.
Step 1: Gather Available Context
Before creating a proto-persona, collect:
- User delegated-research: Interview notes, survey results, support tickets
- Analytics: Usage data, demographics, behavioral patterns
- Market data: Industry reports, competitor user bases
- Stakeholder insights: Sales/support/CS teams who interact with users
- Product context: What problem are you solving? (reference
skills/problem-statement/SKILL.md)
If missing context: Don't fabricate—note gaps and plan delegated-research to fill them.
Step 2: Define the Persona's Identity
Name
Give the persona an alliterative, memorable name (makes it easier to reference).
### Name
- [Alliterative name, e.g., "Manager Mike," "Startup Sarah," "Enterprise Emma"]
Quality checks:
- Memorable: Can the team recall it easily?
- Not generic: Avoid "User 1" or "Persona A"
Bio & Demographics
Describe who this person is in the real world.
### Bio & Demographics
- [Age range]
- [Geographic location]
- [Social status (married, single, family, etc.)]
- [Online presence (active on LinkedIn, avoids social media, etc.)]
- [Leisure activities]
- [Career status (job title, industry, seniority)]
Quality checks:
- Behavioral, not just demographic: Don't stop at "30-40 years old, lives in SF"—add "Works remotely, active in Slack communities, juggles 3 side projects"
- Context-relevant: Only include demographics that influence product decisions
Example:
- "35-45 years old, lives in urban areas (NYC, SF, Austin)"
- "Director-level at mid-sized tech companies (50-500 employees)"
- "Active on LinkedIn and Twitter, attends 2-3 conferences per year"
- "Married with young kids, values work-life balance"
- "Plays rec sports on weekends, listens to business podcasts during commute"
Step 3: Capture Their Voice
Quotes
Use real or representative quotes that reveal how they think and speak.
### Quotes
- "[Quote 1 revealing what they say, feel, or think]"
- "[Quote 2 revealing frustrations or motivations]"
- "[Quote 3 revealing attitudes or beliefs]"
Quality checks:
- Authentic: Use real quotes from interviews/support tickets if available
- Revealing: Quotes should expose mindset, not just facts ("I need better tools" is weak; "I'm drowning in manual work and can't focus on strategy" is strong)
Example:
- "I spend 10 hours a week in status meetings that could be emails."
- "I'm tired of tools that promise automation but require a developer to set up."
- "My team expects me to have answers immediately, but I'm constantly searching for data."
Step 4: Document Their Context
Pains
What problems or frustrations does this persona experience? (Reference skills/jobs-to-be-done/SKILL.md for structure.)
### Pains
- [Pain point 1 related to the problem space]
- [Pain point 2 related to the problem space]
- [Pain point 3 related to the problem space]
Quality checks:
- Specific: "Frustrated with tools" is vague; "Spends 3 hours/week manually copying data between tools" is specific
- Related to your product: Focus on pains your product could address
What is This Person Trying to Accomplish?
What behaviors, actions, or outcomes are they pursuing?
### What is This Person Trying to Accomplish?
- [Behavior or outcome 1]
- [Behavior or outcome 2]
- [Behavior or outcome 3]
Quality checks:
- Observable: Can you see this behavior? ("Get promoted" is internal; "Deliver projects 2 weeks ahead of schedule" is observable)
- Outcome-focused: Not tasks ("use dashboards") but results ("make data-driven decisions faster")
Goals
What are their wants, needs, dreams?
### Goals
- [Goal 1: want, need, or dream]
- [Goal 2: want, need, or dream]
- [Goal 3: want, need, or dream]
Quality checks:
- Short-term and long-term: Include tactical goals ("ship feature by Q2") and aspirational goals ("become VP within 3 years")
- Personal and professional: "Spend more time with family" can be as relevant as "increase team productivity"
Step 5: Understand Their Influences
Decision-Making Authority
Do they have the power to buy your solution?
### Attitudes & Influences
- **Decision-Making Authority:** [Yes/No + context (e.g., "Has budget authority up to $10k, needs exec approval above that")]
Quality checks:
- Procurement reality: If they're a user but not a buyer, note who approves the purchase
Decision Influencers
Who influences their decisions?
- **Decision Influencers:** [Who influences this person? (e.g., "Boss, peers in industry Slack channels, analyst reports")]
Quality checks:
- Specific: Not just "their manager"—name the types of influences (peer recommendations, Gartner reports, Twitter threads, etc.)
Beliefs & Attitudes
What beliefs and attitudes shape their decisions?
- **Beliefs & Attitudes:** [Beliefs/attitudes that impact decisions (e.g., "Skeptical of tools that require training," "Values data-driven decision making")]
Quality checks:
- Relevant to adoption: Focus on beliefs that affect whether they'd use your product
Step 6: Validate and Iterate
- Share with the team: Does this persona resonate? Do they recognize this person?
- Identify gaps: What don't we know? (Add "[ASSUMPTION—VALIDATE]" tags where uncertain)
- Plan delegated-research: Use the proto-persona to guide who to interview next
- Evolve it: As you learn, update the proto-persona (or graduate it to a validated persona)
Examples
See examples/sample.md for full proto-persona examples.
Mini example excerpt:
### Name
- Manager Mike
### Quotes
- "I spend more time in status meetings than actually building product."
Common Pitfalls
Pitfall 1: Demographics Without Behavior
Symptom: "28 years old, lives in NYC, has a dog"
Consequence: Demographics don't explain why someone would use your product.
Fix: Add behavioral context: "Works remotely, active in 5 Slack communities, values async communication tools."
Pitfall 2: Treating Proto-Persona as Fact
Symptom: "Manager Mike would never use feature X because he hates complexity"
Consequence: You're treating an assumption as validated delegated-research.
Fix: Add "[ASSUMPTION—VALIDATE]" tags and plan interviews to test hypotheses.
Pitfall 3: Creating 10 Proto-Personas
Symptom: Trying to model every possible user type upfront
Consequence: Analysis paralysis. Teams can't focus on a primary user.
Fix: Start with 1-2 proto-personas (primary + secondary). Add more as you validate and expand.
Pitfall 4: Fabricating Quotes
Symptom: Quotes that sound like marketing copy: "I love products that delight me!"
Consequence: Fake personas lead to fake empathy.
Fix: Use real quotes from interviews, support tickets, or sales calls. If you don't have quotes yet, note "[PLACEHOLDER—NEEDS RESEARCH]."
Pitfall 5: Never Validating
Symptom: Proto-persona created 6 months ago, never updated
Consequence: You're designing for a hypothesis that may be wrong.
Fix: Plan delegated-research sprints to validate key assumptions. Evolve the proto-persona as you learn. Graduate it to a validated persona when confidence is high.
