Agent Perspective
"I used to spend half my day on password resets and basic questions. Now I handle interesting problems that actually use my expertise." — Senior Support Agent
"The suggested responses save me so much typing, and they're usually 80% right. I just personalise and send." — Support Agent
Lessons Learned
What Worked
- Agent-first approach built trust
- Gradual rollout prevented disruption
- Human oversight maintained quality
- Regular knowledge base updates essential
Challenges Overcome
- Initial agent scepticism (addressed through involvement)
- Hallucination risks (mitigated with review)
- Edge case handling (clear escalation paths)
Recommendations
For similar implementations:
- Start with agent assistance before customer-facing
- Keep humans in the loop for quality
- Invest in knowledge base quality
- Set clear escalation criteria
- Measure and iterate continuously
Conclusion
ChatGPT augmented rather than replaced the support team, improving both efficiency and quality. Success came from careful implementation with appropriate human oversight.
