Data governance - Concept
Single Source of Truth
(Single source of truth)
The agreed place people use when they need a particular fact or figure
What's it for?
Gives everyone one agreed place to use when different copies of an important fact disagree.
For example…
Revenue for board packs always comes from the finance system of record, not from each region's favourite spreadsheet
Finance agrees that the general ledger is the SSOT for official revenue figures, even though CRM and reporting systems hold copies
Think of it like…
It's the official clock on the station wall: if everyone's watch differs, trains disagree; one reference keeps the system moving together
