Current State Analysis
─────────────────────────────────────────
□ Document existing test coverage
□ Identify maintenance pain points
□ Calculate current testing costs
□ Define success metrics

Pilot Phase Timeline (4-6 weeks)
────────────────────────────────────────────────────
Week 1-2:  Tool setup and integration
Week 3-4:  Convert 20-30 critical tests
Week 5:    Train team on new workflows
Week 6:    Measure results and plan expansion

ROI Formula
────────────────────────────────────────────────────
Time Savings:
  Manual test creation: 20h → 4h = 16h saved
  Weekly maintenance: 15h → 3h = 12h saved
  Monthly savings: (16 + 12×4) = 64 hours

Cost Savings:
  QA Engineer Rate: $50/hour
  Monthly savings: 64h × $50 = $3,200
  Annual savings: $3,200 × 12 = $38,400

Investment:
  AI Testing Tool: $500/month = $6,000/year
  Training & Setup: $5,000 (one-time)
  
First Year ROI:
  Savings: $38,400
  Cost: $11,000
  Net Benefit: $27,400
  ROI: 249%
