# Persona-Based Design Testing Test the interface through the eyes of 5 distinct user archetypes. Each persona exposes different failure modes that a single "design director" perspective would miss. **How to use**: Select 2–3 personas most relevant to the interface being critiqued. Walk through the primary user action as each persona. Report specific red flags — not generic concerns. --- ## 1. Impatient Power User — "Alex" **Profile**: Expert with similar products. Expects efficiency, hates hand-holding. Will find shortcuts or leave. **Behaviors**: - Skips all onboarding and instructions - Looks for keyboard shortcuts immediately - Tries to bulk-select, batch-edit, and automate - Gets frustrated by required steps that feel unnecessary - Abandons if anything feels slow or patronizing **Test Questions**: - Can Alex complete the core task in under 60 seconds? - Are there keyboard shortcuts for common actions? - Can onboarding be skipped entirely? - Do modals have keyboard dismiss (Esc)? - Is there a "power user" path (shortcuts, bulk actions)? **Red Flags** (report these specifically): - Forced tutorials or unskippable onboarding - No keyboard navigation for primary actions - Slow animations that can't be skipped - One-item-at-a-time workflows where batch would be natural - Redundant confirmation steps for low-risk actions --- ## 2. Confused First-Timer — "Jordan" **Profile**: Never used this type of product. Needs guidance at every step. Will abandon rather than figure it out. **Behaviors**: - Reads all instructions carefully - Hesitates before clicking anything unfamiliar - Looks for help or support constantly - Misunderstands jargon and abbreviations - Takes the most literal interpretation of any label **Test Questions**: - Is the first action obviously clear within 5 seconds? - Are all icons labeled with text? - Is there contextual help at decision points? - Does terminology assume prior knowledge? - Is there a clear "back" or "undo" at every step? **Red Flags** (report these specifically): - Icon-only navigation with no labels - Technical jargon without explanation - No visible help option or guidance - Ambiguous next steps after completing an action - No confirmation that an action succeeded --- ## 3. Accessibility-Dependent User — "Sam" **Profile**: Uses screen reader (VoiceOver/NVDA), keyboard-only navigation. May have low vision, motor impairment, or cognitive differences. **Behaviors**: - Tabs through the interface linearly - Relies on ARIA labels and heading structure - Cannot see hover states or visual-only indicators - Needs adequate color contrast (4.5:1 minimum) - May use browser zoom up to 200% **Test Questions**: - Can the entire primary flow be completed keyboard-only? - Are all interactive elements focusable with visible focus indicators? - Do images have meaningful alt text? - Is color contrast WCAG AA compliant (4.5:1 for text)? - Does the screen reader announce state changes (loading, success, errors)? **Red Flags** (report these specifically): - Click-only interactions with no keyboard alternative - Missing or invisible focus indicators - Meaning conveyed by color alone (red = error, green = success) - Unlabeled form fields or buttons - Time-limited actions without extension option - Custom components that break screen reader flow --- ## 4. Deliberate Stress Tester — "Riley" **Profile**: Methodical user who pushes interfaces beyond the happy path. Tests edge cases, tries unexpected inputs, and probes for gaps in the experience. **Behaviors**: - Tests edge cases intentionally (empty states, long strings, special characters) - Submits forms with unexpected data (emoji, RTL text, very long values) - Tries to break workflows by navigating backwards, refreshing mid-flow, or opening in multiple tabs - Looks for inconsistencies between what the UI promises and what actually happens - Documents problems methodically **Test Questions**: - What happens at the edges (0 items, 1000 items, very long text)? - Do error states recover gracefully or leave the UI in a broken state? - What happens on refresh mid-workflow? Is state preserved? - Are there features that appear to work but produce broken results? - How does the UI handle unexpected input (emoji, special chars, paste from Excel)? **Red Flags** (report these specifically): - Features that appear to work but silently fail or produce wrong results - Error handling that exposes technical details or leaves UI in a broken state - Empty states that show nothing useful ("No results" with no guidance) - Workflows that lose user data on refresh or navigation - Inconsistent behavior between similar interactions in different parts of the UI --- ## 5. Distracted Mobile User — "Casey" **Profile**: Using phone one-handed on the go. Frequently interrupted. Possibly on a slow connection. **Behaviors**: - Uses thumb only — prefers bottom-of-screen actions - Gets interrupted mid-flow and returns later - Switches between apps frequently - Has limited attention span and low patience - Types as little as possible, prefers taps and selections **Test Questions**: - Are primary actions in the thumb zone (bottom half of screen)? - Is state preserved if the user leaves and returns? - Does it work on slow connections (3G)? - Can forms leverage autocomplete and smart defaults? - Are touch targets at least 44×44pt? **Red Flags** (report these specifically): - Important actions positioned at the top of the screen (unreachable by thumb) - No state persistence — progress lost on tab switch or interruption - Large text inputs required where selection would work - Heavy assets loading on every page (no lazy loading) - Tiny tap targets or targets too close together --- ## Selecting Personas Choose personas based on the interface type: | Interface Type | Primary Personas | Why | |---------------|-----------------|-----| | Landing page / marketing | Jordan, Riley, Casey | First impressions, trust, mobile | | Dashboard / admin | Alex, Sam | Power users, accessibility | | E-commerce / checkout | Casey, Riley, Jordan | Mobile, edge cases, clarity | | Onboarding flow | Jordan, Casey | Confusion, interruption | | Data-heavy / analytics | Alex, Sam | Efficiency, keyboard nav | | Form-heavy / wizard | Jordan, Sam, Casey | Clarity, accessibility, mobile | --- ## Project-Specific Personas If `CLAUDE.md` contains a `## Design Context` section (generated by `teach-impeccable`), derive 1–2 additional personas from the audience and brand information: 1. Read the target audience description 2. Identify the primary user archetype not covered by the 5 predefined personas 3. Create a persona following this template: ``` ### [Role] — "[Name]" **Profile**: [2-3 key characteristics derived from Design Context] **Behaviors**: [3-4 specific behaviors based on the described audience] **Red Flags**: [3-4 things that would alienate this specific user type] ``` Only generate project-specific personas when real Design Context data is available. Don't invent audience details — use the 5 predefined personas when no context exists.
