Decision Points
Layout Approach Selection
IF content-heavy (blog, documentation, learning platform)
├─ 12-column grid system
├─ High text density with clear hierarchy
└─ Consistent gutters for readability
IF marketing/conversion focused (SaaS, e-commerce landing)
├─ Hero-section-first design
├─ Asymmetric layouts allowed for drama
└─ Large whitespace to guide attention
IF e-commerce/catalog heavy
├─ CSS Grid auto-fit for products
├─ Card-based layouts
└─ Filter/search prominence
IF dashboard/app interface
├─ Sidebar + main content
├─ Data density prioritized
└─ Navigation always accessible
IF editorial/magazine style
├─ Mixed grid systems
├─ Large images with pull quotes
└─ Visual variety over consistency
Color Palette Strategy
IF B2B/Enterprise audience
├─ Blue primary (trust, professional)
├─ Neutral-heavy palette
└─ Minimal accent colors
IF Consumer/Lifestyle brand
├─ Warmer primaries (orange, green, purple)
├─ Seasonal accent options
└─ Emotionally-driven choices
IF High-traffic/accessibility-critical
├─ 4.5:1 contrast minimum enforced
├─ Color-blind tested combinations
└─ Dark mode variants required
Visual Hierarchy Decision Tree
IF user goal = immediate action (signup, purchase)
├─ Hero CTA above fold (mandatory)
├─ Single primary action per page
└─ Visual weight on conversion elements
IF user goal = content consumption
├─ Content preview/summary first
├─ Multiple engagement paths okay
└─ Reading experience optimized
IF user goal = exploration (portfolio, catalog)
├─ Grid/gallery layout primary
├─ Quick scanning optimized
└─ Thumbnail → detail flow
Failure Modes
Design by Committee Syndrome
- Symptoms: Multiple visual styles on same page, conflicting brand messages, no clear design system
- Detection Rule: If you see 3+ different button styles or font families on one page
- Fix: Establish design principles document, enforce single source of truth, get stakeholder buy-in on constraints
Decoration Over Function
- Symptoms: Animations without purpose, visual elements that don't aid comprehension, slow loading due to graphics
- Detection Rule: If you can't explain why each visual element helps the user accomplish their goal
- Fix: Remove elements that don't serve user needs, justify every animation with user benefit
Mobile Afterthought Pattern
- Symptoms: Horizontal scroll on mobile, tiny touch targets, desktop navigation on small screens
- Detection Rule: If mobile version requires zooming or horizontal scrolling to use
- Fix: Start mobile-first, test on actual devices, ensure 44px minimum touch targets
Low Contrast Accessibility Failure
- Symptoms: Light gray text (#999) on white, poor readability in sunlight, user complaints about text visibility
- Detection Rule: If any text fails WCAG 4.5:1 contrast ratio when tested
- Fix: Use contrast checker tools, test in bright light conditions, provide high-contrast mode option
Information Architecture Collapse
- Symptoms: Users can't find primary content, navigation doesn't match mental models, high bounce rates
- Detection Rule: If users can't complete primary task within 3 clicks or 30 seconds
- Fix: User journey mapping, card sorting for navigation, prominence for key actions
Worked Examples
Example 1: SaaS Dashboard Redesign
Context: B2B analytics platform, users spend 2+ hours daily in interface
Decision Process:
- Audience Analysis: Power users who value efficiency over aesthetics
- Layout Choice: Sidebar navigation (always accessible) + main content area
- Color Strategy: Blue primary (#2563eb) for trust, minimal accents to reduce cognitive load
- Hierarchy: Data tables get most space, actions are secondary but accessible
Key Design Decisions:
- Dense information display (8px spacing scale)
- High contrast text (#1f2937 on #ffffff)
- Consistent button sizing (40px height for easy clicking)
- Status indicators use semantic colors (green=good, red=alert)
Outcome Validation:
- Task completion improved 23%
- User-reported "ease of use" increased
- Support tickets about navigation decreased 40%
Example 2: E-commerce Product Page
Context: Fashion retailer, mobile-first audience (70% mobile traffic)
Decision Process:
- Traffic Pattern: Mobile browsers, quick decision makers
- Layout Choice: Single-column mobile, two-column desktop
- Visual Priority: Product images > price > reviews > specifications
- Conversion Elements: Add to cart sticky on mobile, prominent but not pushy
Key Design Decisions:
- Hero product image fills screen width on mobile
- Price in large, bold typography immediately visible
- Reviews summary above product details
- Size/color selectors with immediate visual feedback
Novice vs Expert Approach:
- Novice would: Put all product info above fold, use small product images
- Expert catches: Users need large images to evaluate fashion, price-conscious audience needs reviews validation early
Measurable Results:
- Mobile conversion rate increased 31%
- Average session duration increased (users exploring more products)
- Cart abandonment decreased 18%

NOT-FOR Boundaries
Do NOT use this skill for:
- Deep typography decisions (line-height calculations, character spacing) → use typography-expert
- Color theory mathematics or palette generation → use color-theory-palette-harmony-expert
- Design system token architecture or CSS variables → use design-system-creator
- Retro or historical design styles → use windows-3-1-web-designer
- Native mobile app interface design → delegate to native-app-designer
- Detailed accessibility audits → use accessibility-expert
- Animation and micro-interaction specifications → use motion-design-expert
Boundary indicators:
- If user asks for specific font pairing recommendations → typography-expert
- If user needs HSL color calculations → color-theory-expert
- If user wants CSS architecture advice → design-system-creator
- If user needs WCAG compliance checklist → accessibility-expert
