Key Decisions¶

Decision 1: Auto-respond or review first?¶

Chosen: Auto-respond immediately - Reason: Customer satisfaction (instant response) - Risk: 5% incorrect responses (but better than 6-hour wait) - Mitigation: AI includes "Let us know if this helped" feedback

Decision 2: Always generate AI response?¶

Chosen: Yes, for all tickets - Reason: No extra cost (LLM is fast) - Benefit: Support team has context regardless - Safety: AI response marked as "Suggested", human reviews

Decision 3: Track AI effectiveness¶

Metrics: - Did customer reply to AI? (No = resolved) - Did customer escalate? (Yes = AI failed) - Customer satisfaction score on auto-response

Monitoring¶

Key Metrics: - Auto-resolution rate: Target 50%+ - Customer satisfaction with AI response: Target >4/5 - First-response time: Target <2s - Cost per ticket: Monitor trend
