Definition: Single Source of Truth

What is a single source of truth?

A single source of truth (SSoT) is the designated authoritative data source where all of a company's important data are aggregated and stored. Instead of data being scattered across different systems and departments, an SSoT pulls that information together into a single location where it can be managed easily and consistently.

This centralized "master data source" acts as the single, definitive source of data for the entire organization and ensures everyone is viewing the same, up-to-date information rather than conflicting data from multiple silos. Teams from any part of the business can easily access and rely on this trusted reference when they need the latest, most accurate information for confident, data-driven decision-making.
