Not every document needs to be connected on day one. Start with the sources your team already treats as the single source of truth — policy documents, a well-maintained wiki, or a canonical spreadsheet.
Grounding quality improves faster from a small set of trusted sources than from a large set of inconsistent ones.
As confidence grows, additional sources can be layered in, with each one scoped to the AI employees that actually need it rather than shared indiscriminately.
