Definition

Retrieval-augmented generation, or RAG, is a method where an AI system retrieves relevant information before generating a response or taking an action.

01

Why Retrieval Augmented Generation (RAG) matters at work

RAG can make AI more useful with company-specific knowledge without requiring a model to be retrained. It is especially helpful when the source material changes often, such as policies, project status, or product documentation.

02

A practical workplace example

Example

When asked about a customer’s contract terms, an AI retrieves the current signed agreement and uses it to prepare a response.

03

What teams should evaluate

  1. 01

    Track source ownership, freshness, access controls, and retention instead of treating every connected document as equally trustworthy.

  2. 02

    Evaluate retrieval and citation quality separately from the final answer so missing context is not mistaken for a model failure.

  3. 03

    Protect confidential and personal information throughout indexing, retrieval, logging, and deletion workflows.
