RAG Development: Build a Source-Update Process First
A RAG product is only as useful as the information it retrieves. Before tuning prompts or choosing a vector database, decide who owns source material and how the system learns that something changed.
Name the Sources and Owners
List which documents, records, and knowledge bases are in scope. For each, record an owner, update frequency, access rule, and retirement condition. This prevents a useful pilot from quietly becoming a search layer over stale files.
Define the Update Workflow
An update should be traceable: source changes, content is checked, indexes are refreshed, and representative questions are retested. Include a process for removals, because obsolete or withdrawn content can be as harmful as missing content.
| Event | Required action |
|---|---|
| Source changes | Refresh and test affected answers |
| Source is retired | Remove it from retrieval |
| Answer is challenged | Inspect cited source and update path |
Test Retrieval Separately From the Model
Keep a small evaluation set of real questions and expected evidence. Test whether the right source is found before judging the wording of the answer. How to update knowledge in a RAG application and measuring answer quality provide useful next steps.

Why does a RAG system need a source-update process?
Retrieval quality depends on current, well-owned source material. Without updates, the product can return obsolete guidance even if its retrieval and model behaviour are otherwise sound.
