Design 9: Enterprise knowledge assistant
Words made simple
A few useful meanings before you read the explanation.
- RAG
- Find relevant information first, then give it to a model to help answer the question. The answer is only as reliable as the information and checks used.
- Retrieval
- Finding and fetching information that is useful for the current question.
- Grounding
- Connecting an answer to supplied evidence, such as a policy document or a verified database result.
More words from this lesson
- Authentication
- Checking who a user or service is, such as by verifying a login session.
Overview
- A permission-aware assistant over many organizational sources and users.
- It requires identity-linked document access, freshness, and trustworthy source references.
Why this matters
Employees cannot manually search every wiki, drive, and internal manual efficiently.
An everyday example
An enterprise librarian knows which archives each employee may read.
A technical example
Sync documents and permissions, retrieve only eligible active versions, and recheck access on source open.
How it works
- Connect approved sources
- Sync content/ACLs
- Index
- Authenticate query
- Filter/retrieve
- Cite
- Monitor/revoke.
Architecture and flow
Enterprise sources + ACLs → versioned index → identity-aware retrieval → grounded answer.
The insurance assistant example
Claims staff access internal process manuals while customers only access permitted policy sources.
When to use it
Multiple private knowledge sources with maintained permission mappings.
When to avoid it
Do not index everything into one shared corpus without revocation and deletion propagation.
Interview answer
“Enterprise RAG is as much an identity and content-lifecycle system as a generation system.”
Benefits, trade-offs, and production considerations
- Measure ACL sync lag, index freshness, failed connectors, source availability, and unknown answers.
- A fast, relevant answer is still a failure if the source was unauthorized.
