User Mental Model Research

Step 1: Card Sorting Studies

Understand how users naturally group and categorize your content:

// card-sorting-setup.js - Digital card sorting implementation
class CardSortingStudy {
  constructor(items, participants) {
    this.items = items;
    this.participants = participants;
    this.results = [];
  }
  
  // Open card sort - users create their own categories
  openCardSort() {
    return {
      instructions: `
        Group these features into categories that make sense to you.
        Create your own category names.
        Think about how you would expect to find these features.
      `,
      items: this.items,
      allowCustomCategories: true,
      minCategories: 3,
      maxCategories: 8
    };
  }
  
  // Closed card sort - predefined categories
  closedCardSort(categories) {
    return {
      instructions: `
        Place each feature into the category where you would expect to find it.
        Each feature must go into exactly one category.
      `,
      items: this.items,
      categories: categories,
      allowCustomCategories: false
    };
  }
  
  // Analyze card sorting results
  analyzeResults(sortingResults) {
    const analysis = {
      commonGroupings: this.findCommonGroupings(sortingResults),
      categoryNames: this.analyzeCategoryNames(sortingResults),
      outliers: this.findOutliers(sortingResults),
      confidence: this.calculateConfidence(sortingResults)
    };
    
    return this.generateRecommendations(analysis);
  }
  
  findCommonGroupings(results) {
    const pairFrequency = new Map();
    
    results.forEach(result => {
      result.categories.forEach(category => {
        const items = category.items;
        // Count how often items appear together
        for (let i = 0; i < items.length; i++) {
          for (let j = i + 1; j < items.length; j++) {
            const pair = [items[i], items[j]].sort().join('-');
            pairFrequency.set(pair, (pairFrequency.get(pair) || 0) + 1);
          }
        }
      });
    });
    
    // Return pairs that appear together frequently
    return Array.from(pairFrequency.entries())
      .filter(([pair, frequency]) => frequency >= results.length * 0.6)
      .sort((a, b) => b[1] - a[1]);
  }
}

Step 2: Task Analysis Framework

// task-analysis.ts - User task analysis framework
interface UserTask {
  id: string;
  name: string;
  frequency: 'daily' | 'weekly' | 'monthly' | 'occasional';
  importance: 'critical' | 'important' | 'nice-to-have';
  complexity: 'simple' | 'moderate' | 'complex';
  currentSteps: string[];
  painPoints: string[];
  idealSteps: string[];
}

interface TaskFlow {
  taskId: string;
  steps: TaskStep[];
  decisionPoints: DecisionPoint[];
  alternativePaths: AlternativePath[];
}

class TaskAnalyzer {
  analyzeTasks(tasks: UserTask[]): TaskAnalysis {
    return {
      primaryTasks: this.identifyPrimaryTasks(tasks),
      taskFrequency: this.analyzeFrequency(tasks),
      complexityMapping: this.mapComplexity(tasks),
      commonPaths: this.findCommonPaths(tasks),
      navigationRequirements: this.deriveNavigationNeeds(tasks)
    };
  }
  
  identifyPrimaryTasks(tasks: UserTask[]) {
    return tasks
      .filter(task => 
        (task.frequency === 'daily' || task.frequency === 'weekly') &&
        (task.importance === 'critical' || task.importance === 'important')
      )
      .sort((a, b) => {
        const frequencyScore = { daily: 4, weekly: 3, monthly: 2, occasional: 1 };
        const importanceScore = { critical: 3, important: 2, 'nice-to-have': 1 };
        
        const scoreA = frequencyScore[a.frequency] * importanceScore[a.importance];
        const scoreB = frequencyScore[b.frequency] * importanceScore[b.importance];
        
        return scoreB - scoreA;
      });
  }
  
  deriveNavigationNeeds(tasks: UserTask[]) {
    const needs = {
      quickAccess: [],
      contextualActions: [],
      deepNavigation: [],
      searchRequirements: []
    };
    
    tasks.forEach(task => {
      if (task.frequency === 'daily') {
        needs.quickAccess.push(task.name);
      }
      
      if (task.complexity === 'complex') {
        needs.deepNavigation.push(task.name);
      }
      
      if (task.currentSteps.length > 5) {
        needs.searchRequirements.push(task.name);
      }
    });
    
    return needs;
  }
}

Step 3: Mental Model Mapping

# Mental Model Research Template

## User Interview Guide

### Background Questions
1. How do you currently accomplish [task]?
2. What tools do you use?
3. Where do you expect to find [feature]?
4. How do you organize similar items in other apps?

### Category Exploration
1. "If you were organizing a filing cabinet for this app, what would the main folders be?"
2. "What would you put together vs. keep separate?"
3. "What names would make sense to you for these groups?"

### Task Flow Exploration
1. "Walk me through how you would [accomplish goal]"
2. "What would you do if you got stuck?"
3. "What shortcuts would save you time?"

## Analysis Framework

### Common Patterns
- How do users group related items?
- What terminology do they use naturally?
- What are their expectations for navigation depth?
- Which tasks do they want quick access to?

### Mental Model Conflicts
- Where do user expectations differ from business logic?
- Which features don't fit cleanly into user categories?
- What causes confusion in current systems?

Hierarchy Design and Organization

Step 1: Content Inventory and Audit

// content-inventory.js - Systematic content analysis
class ContentInventory {
  constructor() {
    this.content = [];
    this.taxonomy = {};
    this.relationships = new Map();
  }
  
  auditContent(siteMap) {
    const inventory = {
      pages: this.catalogPages(siteMap),
      features: this.catalogFeatures(siteMap),
      contentTypes: this.identifyContentTypes(siteMap),
      relationships: this.mapRelationships(siteMap)
    };
    
    return this.analyzeInventory(inventory);
  }
  
  catalogPages(siteMap) {
    const pages = [];
    
    const traverse = (node, path = '') => {
      pages.push({
        url: node.url,
        title: node.title,
        path: path,
        level: path.split('/').length - 1,
        contentType: this.identifyPageType(node),
        trafficVolume: node.analytics?.pageviews || 0,
        conversionRate: node.analytics?.conversions || 0,
        userRating: node.feedback?.averageRating || 0,
        searchQueries: node.search?.topQueries || []
      });
      
      if (node.children) {
        node.children.forEach(child => {
          traverse(child, `${path}/${child.slug}`);
        });
      }
    };
    
    traverse(siteMap);
    return pages;
  }
  
  analyzeInventory(inventory) {
    return {
      hierarchyDepth: this.calculateAverageDepth(inventory.pages),
      contentDistribution: this.analyzeDistribution(inventory.pages),
      orphanedContent: this.findOrphanedContent(inventory.pages),
      duplicateContent: this.findDuplicates(inventory.pages),
      underperformingContent: this.identifyUnderperformers(inventory.pages),
      navigationGaps: this.identifyNavigationGaps(inventory)
    };
  }
  
  generateRecommendations(analysis) {
    const recommendations = [];
    
    if (analysis.hierarchyDepth > 4) {
      recommendations.push({
        type: 'hierarchy',
        priority: 'high',
        issue: 'Navigation too deep',
        recommendation: 'Flatten hierarchy by promoting important child pages'
      });
    }
    
    if (analysis.orphanedContent.length > 0) {
      recommendations.push({
        type: 'content',
        priority: 'medium',
        issue: 'Orphaned content found',
        recommendation: 'Create navigation paths or consolidate content'
      });
    }
    
    return recommendations;
  }
}

Step 2: Information Hierarchy Design

/* hierarchy-design.css - Visual hierarchy implementation */

/* Clear hierarchy levels */
.nav-level-1 {
  font-size: 18px;
  font-weight: 600;
  color: var(--text-primary);
  padding: 12px 16px;
}

.nav-level-2 {
  font-size: 16px;
  font-weight: 500;
  color: var(--text-secondary);
  padding: 8px 24px;
  border-left: 2px solid var(--border-light);
}

.nav-level-3 {
  font-size: 14px;
  font-weight: 400;
  color: var(--text-tertiary);
  padding: 6px 32px;
}

/* Maximum depth indicator */
.nav-max-depth {
  position: relative;
}

.nav-max-depth::after {
  content: '';
  position: absolute;
  right: 8px;
  top: 50%;
  transform: translateY(-50%);
  width: 4px;
  height: 4px;
  background: var(--warning);
  border-radius: 50%;
}

/* Hierarchy relationship indicators */
.nav-parent {
  position: relative;
}

.nav-parent::before {
  content: '';
  position: absolute;
  left: 8px;
  top: 0;
  bottom: 0;
  width: 1px;
  background: var(--border-light);
}

.nav-children {
  margin-left: 16px;
  border-left: 1px solid var(--border-light);
}

Step 3: Progressive Disclosure Implementation

// progressive-disclosure.ts - Feature revelation system
interface FeatureConfig {

          threshold: 7,
          description: 'After 1 week of usage'
        }
      ]
    });
    
    // Advanced features - revealed when user is ready
    this.addFeature({

          description: 'When explicitly requested'
        }
      ]
    });
  }
  
  checkFeatureAvailability(userId: string, featureId: string): boolean {
    const feature = this.features.get(featureId);
    const progress = this.userProgress.get(userId);
    
    if (!feature || !progress) return false;
    
    // Check prerequisites
    const prerequisitesMet = feature.prerequisites.every(prereq => 
      progress.completedFeatures.includes(prereq)
    );
    
    if (!prerequisitesMet) return false;

Navigation Design Patterns

Step 1: Primary Navigation Structure

<!-- primary-navigation.html - Main navigation structure -->
<nav role="navigation" aria-label="Main navigation">
  <div class="nav-container">
    <!-- Logo/Home -->
    <div class="nav-brand">
      <a href="/" class="brand-link" aria-label="Home">
        <img src="logo.svg" alt="NudgeCampaign">
      </a>
    </div>
    
    <!-- Primary navigation items -->
    <ul class="nav-primary" role="menubar">

    </ul>
    
    <!-- Secondary navigation -->
    <div class="nav-secondary">

          <img src="avatar.jpg" alt="User avatar">
        </button>
      </div>

Step 2: Breadcrumb Implementation

// breadcrumbs.js - Dynamic breadcrumb generation
class BreadcrumbManager {

    `;
  }
}

Search and Findability

Step 1: Search Architecture Design

// search-architecture.ts - Comprehensive search system
interface SearchableContent {
  id: string;
  type: 'page' | 'feature' | 'content' | 'help';
  title: string;
  description: string;
  keywords: string[];
  category: string;
  url: string;
  priority: number;
  lastModified: Date;
}

class SearchArchitecture {
  private searchIndex: SearchableContent[] = [];
  private searchConfig = {
    fuzzyThreshold: 0.7,
    maxResults: 10,
    categoryWeights: {
      'page': 1.0,
      'feature': 0.9,
      'content': 0.8,
      'help': 0.7
    }
  };
  
  buildSearchIndex() {
    // Index all searchable content
    this.indexPages();
    this.indexFeatures();
    this.indexHelpContent();
    this.indexUserContent();
  }
  
  indexPages() {
    const pages = this.getAllPages();
    pages.forEach(page => {
      this.searchIndex.push({
        id: page.id,
        type: 'page',
        title: page.title,
        description: page.description,
        keywords: page.extractKeywords(),
        category: page.category,
        url: page.url,
        priority: page.importance,
        lastModified: page.updatedAt
      });
    });
  }
  
  search(query: string, filters?: SearchFilters): SearchResult[] {
    const normalizedQuery = this.normalizeQuery(query);
    const results = this.searchIndex
      .map(item => ({
        item,
        score: this.calculateRelevanceScore(item, normalizedQuery)
      }))
      .filter(result => result.score > 0)
      .sort((a, b) => b.score - a.score)
      .slice(0, this.searchConfig.maxResults)
      .map(result => ({
        ...result.item,
        relevanceScore: result.score,
        highlightedTitle: this.highlightMatch(result.item.title, query),
        highlightedDescription: this.highlightMatch(result.item.description, query)
      }));
    
    return this.applyFilters(results, filters);
  }
  
  calculateRelevanceScore(item: SearchableContent, query: string): number {
    let score = 0;
    
    // Title match (highest weight)
    if (item.title.toLowerCase().includes(query.toLowerCase())) {
      score += 10;
    }
    
    // Exact title match
    if (item.title.toLowerCase() === query.toLowerCase()) {
      score += 20;
    }
    
    // Description match
    if (item.description.toLowerCase().includes(query.toLowerCase())) {
      score += 5;
    }
    
    // Keywords match
    const matchingKeywords = item.keywords.filter(keyword =>
      keyword.toLowerCase().includes(query.toLowerCase())
    );
    score += matchingKeywords.length * 3;
    
    // Apply category weight
    score *= this.searchConfig.categoryWeights[item.type];
    
    // Apply priority boost
    score *= (1 + item.priority * 0.1);
    
    return score;
  }
  
  // Smart search suggestions
  generateSuggestions(partialQuery: string): SearchSuggestion[] {
    const suggestions = [];
    
    // Popular searches
    const popularSearches = this.getPopularSearches();
    const matchingPopular = popularSearches.filter(search =>
      search.toLowerCase().startsWith(partialQuery.toLowerCase())
    );
    
    suggestions.push(...matchingPopular.map(search => ({
      type: 'popular',
      text: search,
      icon: '🔥'
    })));
    
    // Content matches
    const contentMatches = this.searchIndex
      .filter(item => 
        item.title.toLowerCase().includes(partialQuery.toLowerCase())
      )
      .slice(0, 5)
      .map(item => ({
        type: 'content',
        text: item.title,
        url: item.url,
        icon: this.getTypeIcon(item.type)
      }));
    
    suggestions.push(...contentMatches);
    
    return suggestions.slice(0, 8);
  }
}

Step 2: Contextual Search Implementation

// contextual-search.js - Context-aware search
class ContextualSearch {
  constructor() {
    this.contextStack = [];
    this.userPreferences = {};
  }
  
  // Adjust search based on current context
  contextualizeSearch(query, currentContext) {
    const contextualResults = {
      immediate: [],      // Results from current section
      related: [],        // Results from related sections
      global: []          // Results from anywhere
    };
    
    // Boost results from current context
    if (currentContext.section === 'campaigns') {
      // Prioritize campaign-related results
      contextualResults.immediate = this.searchInSection(query, 'campaigns');
      contextualResults.related = this.searchInSection(query, 'contacts');
    }
    
    // Add global results
    contextualResults.global = this.globalSearch(query)
      .filter(result => 
        !contextualResults.immediate.some(r => r.id === result.id) &&
        !contextualResults.related.some(r => r.id === result.id)
      );
    
    return this.combineContextualResults(contextualResults);
  }
  
  // Smart search shortcuts
  parseSearchShortcuts(query) {
    const shortcuts = {
      'c:': 'campaigns',
      'contact:': 'contacts', 
      'a:': 'analytics',
      'help:': 'help'
    };
    
    for (const [shortcut, context] of Object.entries(shortcuts)) {
      if (query.startsWith(shortcut)) {
        return {
          context,
          query: query.substring(shortcut.length).trim()
        };
      }
    }
    
    return { context: null, query };
  }
  
  // Recent search tracking
  trackSearch(query, results, userAction) {
    this.userPreferences.recentSearches = this.userPreferences.recentSearches || [];
    
    const searchRecord = {
      query,
      timestamp: Date.now(),
      resultsCount: results.length,
      clickedResult: userAction.clickedResult,
      successful: userAction.foundAnswer
    };
    
    this.userPreferences.recentSearches.unshift(searchRecord);
    this.userPreferences.recentSearches = 
      this.userPreferences.recentSearches.slice(0, 20);
  }
}
