  • FAQ optimization from common queries
  • Weekly updates with new information

Quality Controls

Ensuring accuracy:

  • Human review of chatbot escalations

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:

  1. Start with agent assistance before customer-facing
  2. Keep humans in the loop for quality
  3. Invest in knowledge base quality
  4. Set clear escalation criteria
  5. 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.
