Problem

LLMs can produce confident but incorrect answers when they are disconnected from governed content, source metadata, and the workflow context of the person asking the question.

Approach

Designed a RAG approach that organizes source documents, metadata, embedding strategy, retrieval ranking, prompt grounding, and human review paths before exposing answers in support workflows.

Architecture

The architecture separates content ingestion, metadata tagging, embedding generation, vector retrieval, answer generation, source citation, and feedback capture so each layer can be evaluated independently.

Outcome

  • Improved trust in AI-generated answers
  • Created a repeatable pattern for customer and internal support use cases
  • Made knowledge gaps visible before AI rollout
  • Reduced the risk of deploying a generic chatbot disconnected from business context

Lessons learned

  • RAG quality depends on content structure, metadata, and evaluation as much as model choice.
  • Support use cases need clear escalation paths when retrieval confidence is low.
