## Business Impact Analysis

### Problem Identified (Business Impact Score: 9/10)

**Mobile User Abandonment Due to Poor Mobile Experience**

**Symptoms:**
- High bounce rates on mobile devices (75%+ exit without interaction)
- Touch targets too small causing accidental taps and user frustration
- Horizontal scrolling required on narrow screens breaking user flow
- No mobile-optimized navigation or interaction patterns
- Poor accessibility for mobile users with disabilities

**Financial Impact:**
- **Lost Mobile Traffic:** 60% of WordPress users on mobile devices experiencing poor UX
- **Reduced Conversions:** Mobile users 3x less likely to engage with data tables
- **Support Costs:** 40% of mobile-related support tickets cite usability issues
- **Competitive Disadvantage:** Falling behind mobile-first competitors like AG-Grid Mobile

**Root Cause:**
TableCrafter was designed primarily for desktop users with:
1. Fixed-width layouts not optimized for mobile viewports
2. Touch targets below WCAG accessibility standards
3. No mobile-specific interaction patterns (swipe, tap, pinch)
4. Horizontal scrolling as only solution for wide tables
5. Desktop-first responsive design approach
