How to Build a Reliable Enterprise Knowledge Assistant with RAG
Improve internal search and customer answers with retrieval-augmented generation, citations and a disciplined evaluation process.
By Gristip Engineering Team
A knowledge assistant becomes useful when it answers from approved information and shows where the answer came from. Retrieval-augmented generation, or RAG, can provide that grounding—but only when document quality, access control and evaluation are treated as product features.
How to prepare knowledge for retrieval
Start with a defined audience and a curated set of current documents. Remove duplicates, keep ownership metadata and divide content by meaning rather than arbitrary character counts. Retrieval quality usually improves more from better content than from changing models.
- Preserve titles, dates, departments and permission labels.
- Create a process for removing outdated content.
- Use hybrid keyword and semantic search where exact terms matter.
Evaluate answers before employees depend on them
Build a test set containing easy questions, ambiguous requests, missing answers and permission-sensitive examples. Measure retrieval relevance, citation correctness and whether the assistant refuses when evidence is insufficient.
