Retrieval-augmented generation (RAG) lets an AI assistant search approved business information and use the retrieved material when composing an answer. It is useful when responses must reflect current policies, product documentation or internal knowledge that a general model does not reliably know.

What business leaders should know
The business problem
Retrieval-augmented generation (RAG) lets an AI assistant search approved business information and use the retrieved material when composing an answer. It is useful when responses must reflect current policies, product documentation or internal knowledge that a general model does not reliably know.
The practical challenge is to achieve more grounded, traceable answers while controlling the risk of retrieving outdated or unauthorized information. Success depends on well-governed source content, clear ownership and evidence from the operating workflow—not tool adoption alone.
A controlled operating flow
- Ingest and segment approved content
- Create searchable representations
- Retrieve relevant passages
- Generate an answer using that context
- Return citations and capture feedback
Start with test one trusted document collection. Confirm well-governed source content before committing to scale, test the highest-risk assumption in a bounded pilot, and review progress using the listed outcome and quality KPIs.
Where it can help
Potential value
What it cannot reliably do
When should you use it?
Use RAG when trusted information changes regularly or must remain private and source-aware.
When should you not use it?
Do not add RAG when a small deterministic FAQ or database query solves the need more reliably.

Data / inputs required
Security & privacy
Preserve document-level permissions, encrypt stores, filter sensitive data and test for cross-user leakage.
Cost factors
Main factors are content preparation, retrieval infrastructure, model usage, permissions and ongoing evaluation.
Use outcome and quality KPIs
An internal HR assistant answers policy questions from approved handbooks and links employees to the exact policy section.

Retrieving outdated or unauthorized information
What determines the cost?
Main factors are content preparation, retrieval infrastructure, model usage, permissions and ongoing evaluation.
How should success be measured?
Use the KPIs listed on this page, compare them with a pre-project baseline and review quality as well as speed.
Does this remove the need for people?
No. Good implementation redesigns work, keeps accountable owners and uses human judgement where context, exceptions or impact require it.
